D.C. 20314 DAEN-CWE-D 16 May 1975 MEMORANDUM FOR: SECRETARY OF THE ARMY SUBJECT: National Program of Inspection of Dams 1. I submit for transmission to the Congress my Report on the National Program of Inspection of Dams in response to Section 5 of the National Dam Inspection Act (Public Law 92-367). As directed by that section, it reports on the activities performed under the Act. The report submits an inventory of dams in the United States and recommendations for a comprehensive national program for the inspection and regulation of dams of the Nation, including the respective responsibilities which should be assumed by Federal, State and local governments and by public and private interests. 2. The activities performed in this study consisted of compiling the data for an inventory of dams; conducting a survey of each State and Federal agency's capabilities, practices and regulations in regard to the design, construction, operation and maintenance of dams; developing guidelines for the safety inspection and evaluation of dams; and formulating recommendations for a comprehensive national program for the inspection and regulation of the dams of the Nation. No inspections authorized by Public Law 92-367 have been performed due to limited funding and the belief that such inspections of non-Federal dams should be accomplished by the concerned States as part of their normal responsibilities. 3. The National Dam inventory included in the report consists of data on 49,329 dams which are 25 feet or more in height or have a maximum impounding capacity of 50 acre-feet or more. The inventory data consist of the name of the dam or impoundment; the river or stream on which the dam is located; the type of dam; the year completed; purpose of the dam; the height and maximum storage capacity; the name, population and distance from the dam to the nearest downstream city, town or village; the down¬ stream hazard potential; the owner of the dam; and the Congressional District in which the dam is located. 4. The report presents the first Federal study of the safety of dams on a nationwide scale. It reveals that 20,000 of the 49,329 dams of the Nation are so located problems of the approximately that failure or vi DAEN-CWE-D SUBJECT: National Program of Inspection of Dams 16 May 1975 misoperation of the discharge facilities could result in loss of human life and appreciable or greater property damage. The report also finds that existing dam safety programs in most States and in some Federal agencies are either non-existent or inadequate to protect the public from the hazards created by dams. 5. The protection of human life and property from the hazards of dam failure or misoperation is deemed a governmental concern. Although the adequacy and safety of dams owned and operated by numerous governmental agencies, public and private organizations, and private individuals are the obligation of the owners, governmental inspection and regulation is considered necessary to insure the adequacy of design, construction and operation of dams. To further reduce the risk of failure or misoperation, continued surveillance of the dam and appurtenant works is necessary to detect conditions of structural distress or operational inadequacy and to provide a basis for timely initiation of restorative and remedial measures if necessary. 6. Regulatory agencies should be established to regulate all existing and future dams and reservoirs and such agencies should be provided with adequate personnel, financing and powers to enforce their rules and regulations and accomplish their regulatory functions. Such regulatory agencies should review and approve the plans and specifica¬ tions to construct, enlarge, modify, remove or abandon a dam or reser¬ voir; perform periodic inspections during construction; issue certificates of approval upon completion of construction; perform periodic safety inspections and evaluations; and issue notices for required remedial or maintenance work. 7. In Section 5(3) of Public Law 92-367, the Secretary of the Army is directed to report to the Congress his recommendations for a comprehensive national program for the inspection and regulation for safety purpose of dams of the Nation and the respective responsibilities which should be assumed by Federal, State and local governments and by public and private interests. The program I propose for your consideration consists of the following features: a. Implementation of the National Dam Safety Program as outlined in this report. The States and Territories should be encouraged to prosecute the recommended dam safety program encompassing all dams not under Federal authority. Federal agencies owning and operating dams, owning the land on which dams are located and the agencies having existing regulatory jurisdiction over dams should prosecute the recommended dam safety program for the dams under their jurisdiction. Vll DAEN-CWE-D SUBJECT: National Program of Inspection of Dams 16 May 1975 b. The inspection of all existing dams having a high or significant hazard potential should be conducted in accordance with the Recommended Guidelines for Safety Inspection of Dams within a reasonable and practi¬ cable time period after implementation of the National Dam Safety Program. c. Those Federal agencies possessing technical expertise and capa¬ bilities in dam design and construction should be authorized to furnish technical assistance and guidance, upon request, to the States concerning State programs and the elimination or mitigation of any hazardous con¬ ditions found by the States. d. Authority and funds should be provided the Chief of Engineers to maintain the National Dam Inventory. 8. The total cost of implementing and prosecuting a national dam safety program is difficult to forecast; however, evaluation of limited cost experience leads us to believe that the total annual program cost would be about $73,500,000 which represents an average of $1,500 per dam per year. About $65,500,000 would be the annual cost for the programs covering the 43,500 non-Federal dams and $8,000,000 for the 5,500 Federal dams. The cost of performing the initial inspections of the significant and high hazard potential dams would range between $5,000 and $10,000 per dam depending upon the dam's size and complexity. The total annual cost of the initial inspection of the significant and high hazard potential dams would average $30,000,000 if these dams are inspected over a five year period. About $27,000,000 of this average annual cost would be for the initial inspection of non-Federal dams. 9. I am pleased at the opportunity afforded by Public Law 92-367 to report on a proposed comprehensive national dam safety program for the purpose of protecting human life and property from the potential hazards created by dams. I commend the conclusions and recommendations of the report for your consideration in preparing recommendations to the Congress at the earliest practicable date. 10. The report has been coordinated with the States and interested Federal agencies and their comments and views are inclosed. Chief of Engineers viii > George C. Wallace governor State of Alabama GOVERNOR'S OFFICE MONTGOMERY April 11, 1975 > W. C. Gribble, Jr. Lieutenant General, USA Chief of Engineers Department of the Army Washington, D. C. 20314 Dear General Gribble: Thank you for the opportunity to comment on the report which you will submit to the Secretary of the Army as provided by The Dam Inspection Act, P.L. 92-367. The need for a comprehensive national program for the inspection of dams, and their regulation for safety purposes, was brought into sharp focus only two months ago here in Alabama. As you are probably aware, on February 10, 1975, the earthen dam at the Walter Bouldin Hydro Plant suddenly and un- explicably collapsed. Thankfully, there was apparently little property damage and no personal injuries in the areas located downstream as a result of this sudden dam failure. As your report indicates, a sizeable saving might have been realized had an adequate state and/or federal inspection program, in conjunction with the owner's,been in effect. I look forward to receiving a copy of the complete report, with Appendixes, as soon as it is available, and I wish to assure you that the State of Alabama is generally in favor of the proposals outlined in your report. With best regards, I am Sincerely yours, t IA George C. Wallace Governor ix IAUL H. CASTRO GOVERNOR IN REPLY REFER TO: • t- fo -m: <3,*, & I; Office of the Governor STATE HOUSE Phoenix, Arizona 85007 May 8, 1975 W. C. Gribble, Jr. Lieutenant General, U.S. Army Chief of Engineers Department of the Army Washington, D.C. 20314 ATTENTION: DAEN-CWE-0 Dear General Gribble: Thank you for the opportunity to review and comment on the report of the Corps of Engineers to Congress on the National Dam Inspection Program. We have followed with great interest activities leading to preparation of the report and are particularly concerned with how the recommendations might affect state responsibilities and our state safety of dams program. Arizona has had a safety of dams program for many years, but it was only recently that changes in both the managing agency and the funding level enabled us to undertake a program approaching that described in your report. I believe the state should protect its citizens from the type of hazard presented by an unsafe dam and was pleased to see the report recommends that the responsibility for safety of non-federal dams rest with the states. Another area of concern is that the proposed Guidelines for Inspection of Dams, once adopted, will become mandatory and standards to be applied to all dams. Although the report clearly sets forth the intent that the Guidelines serve as guides rather than rigid criteria, this concern and the concept are of sufficient importance to also be treated in the recommendations. l* X W. C. Gribble, Jr. May 8, 1975 Page #2 In Arizona there are a significant number of jurisdictional size, non-federal dams which are located on U.S. Forest lands. The owners of these dams are now subject to regulation by both the State and the Forest Service. In one case the owner has to be responsive on dam safety not only to the State and the Forest Service, but also to the Federal Power Commission. Because this kind of multi-agency regulation places an unnecessary burden of government control upon the dam owners, the concept of single agency control recommended in your report will provide definite improvement. However, the federal agencies whose regulatory control over non-federal dams presently overlaps that of the State do not appear, at this time, to have the technical staff necessary to execute a safety program at the level proposed in the report. If the single agency control recommendation is implemented, it would appear highly desirable to provide for program continuity by maintaining the state's program for these dams until the designated federal agencies have had time to institute an adequate program of their own. In summary, I consider that the overall impact of the recommendations will be beneficial and offer my support. We have enjoyed working with your staff and look forward to receiving the complete report with appendices. RHC/gc XI DEPARTMENT OF THE ARMY OFFICE OF THE CHIEF OF ENGINEERS WASHINGTON, D.C. 20314 REPLY TO ATTENTION OF: DAEN-CWE-D 15 May 1975 Honorable Raul H, Castro Governor of Arizona Phoenix, Arizona 850007 Dear Governor Castro: I thank you for your letter of 8 May 1975 regarding the Chief of Engineers report on the National Program of Inspection of Dams. Copies of your letter and this reply will be appended to the report as submitted to the Secretary of the Army. We agree with your view that the recommended guidelines for safety inspection of dams should not be made mandatory or establish standards to be applied to all dams. The Preface of the guidelines includes a statement that the establishment of rigid criteria or standards is not intended but rather outline the principal factors to be weighed in the determination of existing or potential hazards and to define the scope of the activities to be undertaken in the safety inspection of dams. Evaluation factors, considered reasonable, are included so that comparisons can be made with existing conditions. The present inadequacies of some Federal agencies as well as those of many States in performing dam safety functions are recognized. A primary objective of the recommended National Dam Safety Program is to improve the capabilities of all dam supervising agencies. Your comments and interest in the program are very much appreciated. Two copies of the completed report, with Appendixes, will be furnished the State of Arizona when the report is submitted to the Secretary of the Army.

General w. C. Gribble, Jr. Chief of Engineers Office of the Chief of Engineers Department of the Army Washington, D. C. 20314 Dear General Gribble: Governor Brown has requested that I reply to your letter of March 18, 1975, regarding the text of your report to the Secretary of the Army on the National Program of Inspection of Dams. As you know, California has an effective program in dam safety. I note that the report suggests regulation of dam construction and operation, for safety, patterned after our statutes and regulations. I concur in your general approach to the program for dam safety; that is, the primary responsibility for safety of non-Federal dams should be the states'. I do not concur in the conclusion that non- Federally-owned dams that are located on Federal lands or under the jurisdiction of Federal regulatory agencies be classified as Federal dams. Some of these Federal agencies do net have the expertise to properly judge the safety of these dams and must either develop the necessary expertise or contract to another Federal agency that is qualified. As the intent of the proposed program is to urge the states to pass the necessary legislation and to develop the exper¬ tise to administer a dam safety program, it would be appropriate for the states to approve the safety of all dams other than those specifically owned by a Federal agency. I believe that early implementation of the proposed "Phase I" in¬ spection of the national program is necessary as the first step ft xiii Lt. General W. C. Gribble, Jr. -2- toward assuring public safety from dam failure. The implementation of "Phase I" should be in close cooperation with the various states utilizing whatever information is already available at the State level. In California, our records on dam safety are sufficiently complete to preclude any additional expenditure by the Federal Government. Sincerely, Deputy Secretary for Resources v-^A Secretary for Resources xiv DEPARTMENT OF THE ARMY OFFICE OF THE CHIEF OF ENGINEERS WASHINGTON, D.C. 20314 IN REPLY REFER TO DAEN-CWE-D 15 May 1975 . Mrs. Claire T. Dedrick Secretary for Resources The Resources Agency of California Resources Building 1416 Ninth Street Sacramento, California 95814 Dear Mrs. Dedrick: We appreciate the letter from your agency dated 30 April 1975 (signed by Mr. Larry E. Moss) regarding the Chief of Engineers report on the National Program of Inspection of Dams. Copies of your letter and this reply will be appended to the report as submitted to the Secretary of the Army. In regard to the question of jurisdiction over private dams located on Federal lands, we believe that the Federal Government has a primary responsibility to insure that Federal lands are not utilized in a manner detrimental to the public's safety. I believe we can agree that such hazards could develop in those cases where a State does not have an adequate dam safety program and the appropriate Federal agency neglects its responsibility in this regard. A cooperative effort between Federal agencies and the States to promote the safety of private dams on Federal lands would appear appropriate and desirable. The present inadequacies of some Federal agencies as well as those of many States in performing dam safety functions are recognized. A primary objective of the recommended National Dam Safety Program is to improve the capabilities of all dam supervising agencies. Your comments are very much appreciated. Two copies of the completed report, with Appendixes, will be furnished the State of California when tne report is submitted to the Secretary of the Army. Sincerely yours, Major General, USA Acting(X3hief of Engineers xv ELLA GRASSO GOVERNOR April 28, 1975 W. C. Gribble, Jr., Lieutenant General Chief of Engineers Department of the Army Washington, D. C. 20314 Dear Lieutenant Gribble: Thank you for the opportunity to review and comment on the report prepared through the Chief of Engineers concerning a national program of dam inspection. I have asked our Department of Environmental Protection to review your report and their comments are set forth below. We appreciate the necessity for the Army Corps to conform with P. L. 92-367 and the criteria contained therein. However, the failure of dams smaller than those considered in the law could result in significant damages and possibly loss of life. According to the federal program summary, there are 676 dams of significance in Connecticut. Our program inventory shows approximately 1036 dams which could be considered to be a hazard to life and property. A central problem with dam regulatory programs is that methods of characterizing the degree of hazard a dam poses to life and property are not precise. Various experts have given conflicting opinions as to how "hazard" should be determined. It appears necessary to resolve this question by developing reasonably precise and accurate methods of evaluating hazard before continuing too far into phase II of the program, as the methodology may influence the data obtained in phase II. Phase I data exists on magnetic tape. In its present form it is not particularly useful to our state dam program. Is it possible to obtain information from the existing tape in processed form, i.e., sorted and listed by characteristics of the dams and impoundments? Also, can we add coded data to the tape such as date of last inspection, legal action pending, etc.? xvi W. C. Gribble, Jr., Lieutenant General Page -2- April 28, 1975 Phase II will require, in some cases, extensive expenditures for data gathering and evaluation. Have guidelines been prepared to assure the extent of evaluation will be uniform from investigator to investigator? Without detailed guidelines, conditions may develop which could result in excessive examinations of some structures and marginal examinations of others. Item 10-(5) on page 11 recommends that State regulatory agencies be authorized to perform required repairs if owners fail to do so. Connecticut is not able to bear this financial burden. A central problem is the high cost of design and construction. Has the Army Corps made estimates of annual expenditure that would be required to carry out this provision? Will federal funds be available to permit the State to assume this responsibility? Item 12, page 14, indicates about 11% of the subject dams are federal structures; 89% are non-federal structures. The proposed funding for the program shows just about the same breakdown of total anticipated funds. This seems unreasonable as the design and condition of federal dams should be generally excellent in view of the high standards followed in the planning, design and construction'phases, and the significant operation and maintenance funds these dams have received annually since their construction. Inspection and inventory should therefore be relatively inexpensive as compared to the non-federal dams. The cost-effectiveness of the proposed program as described in the last paragraph of section 13, page 15, will only be achieved if funding is obtained for any redesign, repair or removal indicated by inspections. The cost figures presented do not appear to reflect this vital aspect of the program. Our experience at the state level has been that high hazard and high cost of repair tend to go hand in hand, and that private property owners are no t capable of making the level of expenditure required to remove the hazard. Section 14, paragraph (a) again refers to establishing priorities on the basis of the degree of hazard. This can only be done if a generally accepted, precise method of determining hazard can be worked out. Section 15, paragraph (b) suggests it may be possible to fund the supervision of non-federal dams through state funds. We do not believe this is a reasonable assumption in view of our current state deficit and the competition for state funds by existing programs. XV1X W. C. Gribble, Jr., Lieutenant General Page -3- April 28, 1975 We believe the program outlined is necessary and important. The funding made available to conduct the phase I inventory has permitted Connecticut to update and revise our existing dam inventory and we are grateful for the assistance provided to perform this update. We look forward to the opportunity to participate in future phases of a program that will ultimately reduce the exposure of our citizens and others to the hazard of dam failures. With best wishes, Cordially, ELLA G^ASSO Governor xviii DEPARTMENT OF THE ARMY OFFICE OF THE CHIEF OF ENGINEERS WASHINGTON, D.C. 20314 REPLY TO ATTENTION OF: DAEN-CWE-D 12 May 1975 Honorable Ella Grasso Governor of Connecticut Hartford, Connecticut 06115 Dear Governor Grasso: I thank you for your letter of 28 April 1975 regarding my report on the National Program of Inspection of Dams. Copies of your letter and this reply will be appended to the report as submitted to the Secretary of the Army. The hazard classifications listed with the inventory data are tentative and it may be necessary to reclassify some of the dams when additional information becomes available. The inspection guidelines provide parameters for classifying dams with respect to both size and hazard potential and recognize the possibility that dams will need to be reclassified from time to time. It should be possible to retrieve inventory data in specific statistical forms. Procedures are now being developed so that this can be done to satisfy certain anticipated requirements. We would welcome your sugges¬ tions or comments pertaining to your needs in this regard. With respect to adding coded data to the inventory, this will be possible. Our report recommends that the inventory be maintained current and that authority and funds be provided the Corps of Engineers to carry on this work. Individual States might also be furnished copies of that portion of the master cape containing dams within their States so that they could add, revise or extract information directly. Recommended guidelines for safety inspections have been prepared and will be included in the report as Appendix D. A draft of the guidelines was published in the 28 August 1974 Federal Register (Volume 39, No. 168) for review and comment by all interested parties. We have not attempted to assess the total impact on economic resources of the follow on design and modification work. The information needed DAEN-CWE-D Honorable Ella Grasso 12 May 1975 for preparing such estimates can be developed only by the inspection program. We believe that the prosecution of that portion of the pro¬ gram concerned with non-Federal dams is a State responsibility. How¬ ever, your concern about the availability of Federal financial assistance will be made known to the Secretary of the Army by the inclusion of your letter with our report. While the condition of those Federal dams under the jurisdiction of Federal agencies having major responsibilities for dam construction should generally be much better than non-Federal dams, such would not be the case for the bulk of the 5,500 dams classified as non-Federal. Included in this category are private dams located on Federal lands and other dams under jurisdiction of Federal agencies lacking suitable capabilities in the field of dam design, construction and inspection. Your comments and interest in the program are very much appreciated. Two copies of the complete report, with Appendixes, will be furnished the State of Connecticut when the report is submitted to the Secretary of the Army.

Gribble, Jr. , USA Chief of Engineers Office of the Chief of Engineers Department of the Army Washington, D.C. 20314 Dear General Gribble: Thank you for your letter of March 18, 1975, requesting our comments on your report entitled, "National Program of Inspection of Dams", Volume I. We have read your report with great interest and find it very compre¬ hensive and factual. We have no recommended change for your report. We would like to take this opportunity, however, to thank the Corps of Engineers for preparing the inventory of dams in the State of Hawaii, which identified a total of 119 dams and reservoirs, most of which are considerably smaller than those throughout the nation. Only five of the reservoirs in the State have dams that exceed 23 feet in height. The construction of large dams in Hawaii has been a relatively minor concern and legislation on dam design, construction, operation and maintenance has not been provided for. The State, however, is reassessing its responsibility for regulation of dams. The extent of the State's involvement needs to be weighed against its financial resources to prosecute dam safety programs as recommended in your report. We thank you for the opportunity to review your report and we assure you that we are seriously considering the matter of a dam safety program for Hawaii. With warm personal regards, I remain, Yours very truly XXXI STATE HOUSE BOISE, IDAHO 83720 OF IDAHO BETPARTMENT OE WATER RESOURCES April 17, 1975 Mr. W. C. Gribble, Jr. Lieutenant General, USA Chief of Engineers Department of the Army Office of the Chief of Engineers Washington, D.C. 20314 Dear Mr. Gribble: This Department has been asked by Governor Andrus to respond to your March 18, 1975 request for comments on the report entitled "National Program of Inspec¬ tion of Dams, Volume 1". The people of Idaho agree whole-heartedly with the idea that regulation of dams is necessary to provide for public safety. For this reason, our 1969 state legislature revised Idaho's dam safety statutes to agree closely with what is now recommended by the USCOLD Model Law. It is our hope that any national effort to regulate dam safety be restricted to having each State conform to provisions of the USCOLD Model Law as set forth in Section 10.b of your report. Such action by the individual States would insure a sound approach to dam safety at a reasonable cost and effort. Dam safety regulation would remain where you indicated in Section 11.c that it should be - with the States. (Your proposed definition of a "Federal Dam" is so excessively broad that it certainly contributes nothing toward the idea of State control of dam safety.) While giving each State relative freedom to adopt measures it feels would be appropriate for its jurisdiction would result in great variation among the States, I cannot agree with Conclusion No. 3 in your report which implies that anything other than a unified approach nationwide would be inadequate. It would also appear reasonable that different standards for existing dams could be adopted than are applied to new facilities as long as safety were still the prime consideration. Technology has changed rapidly and features reasonable to request at a new facility may not warrant costly work to upgrade an old dam that is proven to be basically safe. Such costs could amount to a serious nationwide impact and should be considered carefully. The most effective way in which the Federal Government can insure that each State adopts reasonable controls is to provide training for State personnel and supplemental funding that would allow each State to be adequately staffed and equipped to do a good job. This would not be accomplished by having a Federal "superagency" step in with a massive program. Strong Federal support for State efforts to regulate all dams in each State appears to be the only realistic way xxiii Mr. W. C. Gribble, Jr. April 17, 1975 to provide safe dams at a reasonable cost to the public. Having one impartial agency in each State with the expertise to review safety at all dams would eliminate some of the obvious problems inherent in having some of the inadequately staffed Federal agencies not only design, construct, and operate a dam but also pass judgement on whether or not they have done a good job. In addition to the above comments regarding the proposed approach to the nationwide dam safety situation, I also have the following comments about specific sections of the report: Section 6: 1 am not aware of how the inventory was conducted in other States, but in Idaho, this Department provided most of the inventory data for all Federal dams after the Federal agencies failed to comply with your require¬ ments. Sections 7.b & 11.b: The report indicates that MESA has authority over mining impoundments to provide for safety of mines - what about public safety when no danger to the mine exists? Also, MESA's new authority over coal-waste deposits would apparently not affect current practices with regard to other types of mining which also utilize waste deposit areas. I would be interested in knowing what MESA's jurisdiction is over mining impoundments that were abandoned years ago and existing impoundments after mining ceases. Would such a dam still be considered a "Federal Dam" if MESA ceased exercising control over the operation? Section 13: From my understanding of the flooding that occurred in Rapid City in South Dakota, it appears very misleading to infer that such a situation would not have occurred with proper dam safety regulation. My understanding of the Rapid City flood is that it was caused by runoff exceeding normal spillway design standards. Significant damage would have occurred regardless of whether or not the dam had washed out. Tour "Guidelines for Safety Inspection of Dams" do not appear to agree with the iaua expressed here that you are working for a "program that would virtually eliminate all preventable dam failures". It would seem more accurate tc say the program should eliminate significant property damage or loss of life. Otherwise there would be no purpose in the Guidelines referring to hazard or size classifications. Every dam would be required to handle a Probable Max Flood - an unreasonable requirement in many cases. Thank you for the opportunity to comment on this report. xxiv AK.D :WRG:ldt DEPARTMENT OF THE ARMY OFFICE OF THE CHIEF OF ENGINEERS WASHINGTON. D.C. 20314 REPLY TO ATTENTION OF: DAEN-CWE-D 9 May 1975 Mr. A. Kenneth Dunn Administrator, Operations Division Department of Water Resources State House Boise, Idaho 83~20 Dear Mr. Dunn: I thank you for your letter of 17 April 1975 regarding the Chief of Engineers report on the National Program of Inspection of Dams. Copies of your letter and this reply will be appended to the report as submitted to the Secretary of the Army. The term "Federal Dams" was used to simplify the discussion of responsibility for supervising dam safetv. It is defined in the report as dams owned and operated by Federal agencies, dams located on lands under Federal jurisdiction, and dams under regulatory jurisdiction of Federal agencies. The inventory data indicate that only about 117. of all dams conforming to the height and capacity parameters of Public 1 aw 92-367 fall under this definition of "Federal Dams." The conclusion in paragraph 16a(3) of the report, which states a need for a unified approach to the dam safety problem, was based upon existing regulatory functions and practices in all the States and Federal agencies as revealed by the questionnaire survey. With few exceptions these practices and capabilities are considered inadequate, and we believe that improvement could best be attained through a concentrated national effort. Idaho has excellent legislative authority and perhaps one of the tetter existing surveillance programs; however, tne adeqnac of the reported $18,500 annual budget for supervising 433 dams and reservoirs could be questioned. The need for a unified effort in this reyard was also expressed by the participants at the Engineering Foundation Conferences at the Asilomar Conference Grounds on 23-28 September 19~3 and at: ilenniker, New Hampshire, 4-9 August 1974. xxv DAEN-CWE-D Mr. A. Kenneth Dunn 9 May 1975 We agree with your view that standards and design criteria for new dams should not be made mandatory for existing dams. To this end, inspection "guidelines" rather than "standards" were developed. The guidelines do not establish rigid criteria but rather outline principal factors to be weighed in determining existing or potential hazards and define the scope of activities to be undertaken in safety inspections. Evaluation factors, considered reasonable are included so that comparisons can be made with existing conditions. The report does not recommend the establishment of a Federal "superagency," but rather that the program be prosecuted by the individual States in the case of all dams not under Federal authority, and by the appropriate Federal agency for dams under its individual authority. Present inade¬ quacies of some Federal agencies as well as those of many States in per¬ forming dam safety functions are recognized. A primary objective of the recommended National Dam Safety Program is to improve the capabilities of all dam supervising agencies. The inventory data for Federal dams were, for the most part, supplied by the Federal agencies. However, where data were lacking or in need of verification, the States and private engineering firms collecting the data for non-Federal dams were contracted to obtain the supplemental information. Idaho's effort in this regard, I have been advised, was satisfactorily reimbursed. The failure to mention the help of States and private engineering firms in collecting the supplemental data for Federal dams was an oversight which we regret. I appreciate your bringing this to my attention in time to correct the report before its submission. In reply to your questions about the jurisdiction of MESA, our under¬ standing is that the present authority of that Agency with respect to mining impoundments is concerned with the safety of mines and coal miners on coal mine property only, and not the safety of the general public. Currently proposed revisions to regulations concerning coal refuse piles would not affect waste deposits from other types of mining. The question of abandoned coal refuse piles is being addressed in these proposed revisions; and MESA's or any other agency's control over abandoned waste embankments probably would depend upon the plans for abandonment, particularly with respect to whether or not provisions are made to prevent impoundment of water. All should recognize that the prosecution of the recommended dam safety program would require additional administrative authority for Federal agencies as well as additional legislative authority for many of the States. A more detailed discussion of your questions about current authorities of MESA may be obtained by writing to the Administrator, Mining Enforcement and Safety Administration, Washington, D.C. 20240. xx vi DAEN-CWE-D Mr. A. Kenneth Dunn 9 May 1975 While an event of disaster proportion probably would have occurred at Rapid City had the Canyon Lake Dam not failed, much of the damage and many of the deaths were attributed in news accounts to the failure. In this regard, I refer you to the 15 June 1972 issue of the Engineer¬ ing News-Record. The failure was also cited as one of the events leading to passage of P.L. 92-367, as attested by the Congressional Record-House, 24 July 1972, pages H6325 and H6827. It was also mentioned as a significant contributor to the disaster in the Com¬ mittee on Public Works Report No. 92-1232, National Program for Inspec¬ tion of Dams. The statement in paragraph 13 of the report about virtually eliminating all preventable dam failures was intended to relate to significant failures, such that would require disaster assistance (see parenthetical expression in same sentence). Your suggested clarification is very helpful and will be incorporated into the report. Your comments are very much appreciated.

Indiana has, for many years, operated programs involving the review and approval of plans for dams prior to construction; requiring professional certification of construction in accordance with approved plans; and conducting annual inspections for the purpose of ensuring proper maintenance and repair. I believe that such programs are reasonably adequate and, therefore, see no need for the imposition of federal legislation in this regard. I would add that if federal program requirements are imposed, then the federal government should provide adequate and continuing funding to the states to cover such costs. As a final note, I would add the observation that, in the light of the corps' recent assertion concerning expansion of their jurisdiction and of recent federal district court rulings, the states are having great difficulty in visualizing just what is meant by your recommendation (a) that "all states and territories should be encouraged to prosecute dam safety programs encompassing all dams not under federal authority" (emphasis added).

Fortunately the State of Iowa has had what we consider an effective regulatory program dealing with the review of applications and plans for structures of this nature. The state also has a limited in¬ spection and maintenance program in effect, but to comply with the proposed inspection program you have outlined a much greater effort would have to be made in this area. We hope that sufficient federal funding can be made available to the states to enable them to carry out their responsibility in connection with Public Law 92-367 and that sufficient advance warning could be provided to permit states to properly gear up to utilize federal funding for the inspection purposes.

This program has generated much interest in Kentucky because of the recognized need as well as the fact that our Department for Natural Resources and Environmental Protection obtained the inventory data for non-federal dams in Kentucky. They also previously reviewed and commented on the recommended guidelines for safety inspection of dams as presented in Appendix D of your report. The Commonwealth of Kentucky is in complete agreement with the conclusions and recommendations presented in your report and will support, in any way possible, a dam safety program developed in accordance with these recommendations. It must be noted that we feel that the recommendations should have been extended to cover the matter of funding for the program.

While Louisiana does not have an appreciable number of impound ments having a high hazard potential, we do recognize our re¬ sponsibilities in protecting the public and downstream improve ments. The State of Louisiana is fortunate in having an engi¬ neering agency, the Department of Public Works, that can admin ister such a program in our behalf.

Chief of Engineers Department of the Army Office of the Chief of Engineers Washington, D. C., 20314 Dear Mr. Gribble: After reviewing the National Program of Inspection of Dams, I find it to be a sensible approach to the maintaining of our dams in a safe condition. The safety of dams should, however, remain the responsibility of each state, supplemented with Federal financial and technical assistance for national conformity. The laws pertaining to dam safety in Maine are crisis-oriented, with limited control of dams and reservoirs in emergency situations caused by flooding. The State Inspector of Dams and Reservoirs only acts upon a complaint of ten resident tax¬ payers. The Maine Section of American Society of Civil Engineers has drafted dam safety legislation based on the U. S. Committee on Large Dams Model State Law to be submitted to the 107th Maine Legislature, which is presently in session. This proposed law should act in conjunction with PL 92-367.

I concur with all the recommendations contained on page 19 of the report. I am particularly pleased with your recognition of the State's responsibility, under the police powers of the State, to protect the health, safety and welfare of its citizens, in recommending the states carry out a dam safety program involving all non-Federal dams. However, I feel if such a program is to be implemented by the states, some financial assistance will need to be provided by Congress. I feel that Michigan's present dam safety statute, although de¬ ficient in some areas, is adequate to carry out a dam safety program of non-Federal dams in this State, as outlined in your report. As stated earlier, I feel that some financial assistance will be needed to implement such a program that would encompass the nearly 600 non-Federal Michigan dams. It is my recommendation that Congress implement a National Dam Safety Program as outlined. The disasters that have occurred as the result of dam failures in this nation in recent years, cer¬ tainly point out the need for such a program. Kind personal regards.

Chief of Engineers Department of the Army Office of the Chief of Engineers Washington, D.C. 2031U Dear General Gribble: A review of your report, "National Program of Inspection of Dam", Volume I, has been made. Contained in your report and particular interest to us was the proposed state supervision of inspection of non-Federal dams. Contained in this letter are comments on that proposal and comments on the existing laws under Minnesota Stat¬ utes and how both pertain to safety inspections of dams to ensure adequate protection to those endangered by failure of dams and reservoirs. Under Minnesota Statutes Chapter 105.£2, the Commissioner of Natural Resources is authorized upon complaint or upon his own initiative to examine any reservoir, dam, control structure, or waterway obstruction. Under Minnesota Statutes Chapter 105.U8, all dams owned by the State or erected upon lands owned or controlled by the State shall be maintained under the direction of the Commissioner of Natural Resources and the same shall be operated under his direction and control. In 1973 provisions were made under Minnesota Statutes to provide for a State program to repair and reconstruct dams owned by local units of government consisting of counties, cities, villages, or boroughs. On a cost-sharing basis, each year $125,000 is avail¬ able in grant-in-aid to those governmental units for dam repair and reconstruction. This Statute provides that the program be administered by the Commissioner of Natural Resources. Minnesota has approximately 600 dams in the category of non-Fed¬ eral dams which conform to the size requirements of the National Inventory of Dams. We have no program for systematic or regular safety inspections of these non-Federal dams. Contained in your report is an estimated cost of $1,500 per dam per year for the initial inspection. These costs do not include the costs of in-depth studies, investigations or analysis. With the Implementation of the National Program of inspection of dams the State of Minnesota would anticipate difficulties in allocat¬ ing personnel and funding of an adequate program. xLi AN EQUAL OPPORTUNITY EMPLOYER -2- April U, 1975 W. C. Gribble, Jr. In summary, under Minnesota Statutes the Commissioner of Natural Resources is authorized to inspect any dam in the State, but in¬ spections in most cases are made only after a request has been filed. The State of Minnesota makes a nominal amount of money ($125,000 per year) through grants-in-aid to local units of govern¬ ment for repair and reconstruction of dams. The State of Minne¬ sota has no on-going program for dam inspection. According to your estimated initial inspection cost of $1,500 per dam per year, inspection of Minnesota's 600 non-Federal dams would require an enormous amount of money. The State of Minnesota does not have the funds nor personnel to supervise the inactment of the Nation¬ al Program of Inspection of Dams. We recommend that Federal financial assistance be provided for the initiation and implemen¬ tation of National Program of Inspection of Dams. Yours very' truly. 7 V/v 0^1 ce<' ?^H.

Hollenstein Chief Hydrologist Division of Waters, Soils and Minerals Department of Natural Resources Centennial Building St. Paul, Minnesota 55155 Dear Mr. Hollenstein: I thank you for your letter of 4 April 1975 regarding my report on the National Program of Inspection of Dams. Your letter and this reply will be appended to the report when submitted to the Secretary of the Army. Your comment pertaining to the estimated cost of the initial inspections indicates that some clarification of the report is required. The average cost of $1,500 per dam per year pertains to the total cost of conducting the entire program which includes all functions of the regulatory agency. This average annual cost includes the cost of performing the periodic technical inspections of the significant and high hazard potential dams at five year intervals. Based upon the estimated number of dams in the significant and high hazard potential category in the entire nation, the average annual cost of performing the initial inspections represents about 40 percent ($600) of the estimated $1,500 average annual cost per dam to conduct the recommended program. Your comments are very much appreciated. Two copies of the complete report, with Appendixes, will be furnished the State of Minnesota when the report is submitted to the Secretary of the Army. Sincerely yours. CHRISTOPHER S. BOND GOVERNOR Executive Office State of Missouri Jefferson City April 18, 1975 Lt. General W. C. Gribble, Jr. Chief of Engineers Department of Army Office of the Chief of Engineers Washington, D. C. 20314 Dear General Gribble: Thank you for the opportunity to review and comment upon your report on the National Dam Inspection Program. The Inventory Program carried out in Missouri by state personnel is considered in the best interest of our state. Our Department of Natural Resources reports that the estimated unit costs of the "Phase I Inspection Program" appear somewhat high, principally because staff members indicate that they were able to identify hazardous dams and/or dams "needing additional investigation and study" during the course of their inventory work. We are opti¬ mistic that substantially less emphasis than indicated would be required in the initial phase of the inspection program in Missouri. The provision that Phase II investigation costs (in the case of an existing structure) are to be borne by the non-Federal owner is troublesome, however, we see no practi¬ cal alternative. Legislation currently under consideration by the Missouri General Assembly does not address this problem, although it provides for repair or demolition of hazardous structures, with the expense borne by the owner or by the state if the owner cannot be held responsible. The proposed legislation calling for a State Dam Safety Program is modeled after the USCOLD Model Law, and I am hopeful that it will progress through the legislature during the current session. xLiv Lt. General W. C. Gribble April 18, 1975 I urge the continuance of the National Dam Inventory Program so that the national effort can be current without major expenditure or significant lapse.

JUDGE GOVERNOR April 28, 1975 Mr. W. C. Gribble, Jr. Lieutenant General, USA Chief of Engineers Department of the Army Office of the Chief of Engineers Washington, D. C. 20314 Dear General Gribble: I have referred the report by the Department of the Army, entitled "National Program of Inspection of Dams" to the Director, Montana De¬ partment of Natural Resources and Conservation for review. I am pleased to report that he is in substantial agreement with this document and has submitted the following comments, in which I concur. Model Law - Montana does not have an effective dam safety law. The existing law contains no provisions for submission of plans and specifi¬ cations for approval prior to construction. It does permit inspections of dams when such action is deemed warranted, but provides no means of enforcement of remedial measures recommended. Montana supports the USCOLD Committee Model Law draft and the recommendation that the Federal Government provide incentives for passage of effective State Dam Safety Laws. Inventory of Dams - An inventory of dams would be of value to individuals, private organizations and public entities. However, without an effective dam safety law the state is hard pressed to maintain records on construction, rebuilding and removal of dams. Technical Capabilities - It is questionable whether there are sufficient numbers of engineers trained and experienced in design and construction of dams in this state to meet the initial demands of such a program. Economic Resources - Approximately 1,400 dams in Montana would come under the provisions of this model law. On the basis of estimates contained in the report the cost would be about 2.1 million dollars. Without state or federal subsidies considerable financial hardship could result to owners. This would be particularly true in the case of Phase II inspections. I wish to express my appreciation for the opportunity to review and comment on this report. vLvi cc: Gary Wicks . liiMi J.

C. 20314 Subject: Your DAEN-CWE-D Dear General Gribble: Thank you for providing me with a copy of your report to the Secretary of the Army to date with the National Dam Inspection Program and the Inventory of Dams authorized by Public Law 92-367 and an opportunity for our comments. I wish to affirm my views that this State should and will continue to assume the primary responsibility for the safety of non-federal dams in Nebraska. Most dams that have been constructed in Nebraska have been constructed by the Soil Conservation Service with significant amounts of federal funds provided; however, not in relative proportion with federal funds or state fees for inspection and maintenance. The Nebraska Department of Water Resources has the authority for inspecting dams in this State, and this Department reviews the pains for structural safety and has carried on an inspection program of the non-federal dams for approximately seven years. We have not carried on any inspection during construction of dams by the Department of Agriculture under the 566 program as this federal agency carries on the inspection during construction and during the first three years after the dams are turned over to an agency such as the water¬ shed districts. The watershed districts have now been brought under the authority of 24 natural resources districts which have been organized in Nebraska. xLvii Lieutenant General W. C. Gribble, Jr, April 23, 1975 He wish to emphasize that heretofore the filing fees for examination and approval of plans in Nebraska has not oeen adequate for the funding of inspections as you have suggested in the USCOLD Model Law as being an excellent example of an adequate inspection program. The Department of Water Resources has in the past budgeted for the purpose of inspection of darns, but these budgets must be increased if we are to meet the federal requirements as mentioned in Volume i per¬ taining to the "National Program of Inspection of Dams." We would hope that federal funds would be available, perhaps on a matching basis, to carry on the inspection program to provide incentives, quality control, procedures for consistency, technical advice and training of inspectors. I would appreciate the continuance of the Corps of Engineers to inform me as co the procedure for the National Dam Inspection Program.

A copy of your letter and this reply will be appended to the report as submitted to the Secretary of the Army. The Mining Enforcement and Safety Administration's responsibility in regard to tailings dams is outlined in the 1966 Federal Metal and Nonmetallic Mine Safety Act. This responsibility includes the safety of water and silt impoundments which may affect the safety of the mining operations and miners. The response to our questionnaire survey indicated that MESA inspects such dams as a regular part of mine inspections and also requires the dam operator to perform inspections at regular intervals. MESA also investigates any complaint concerning safety at mines. A more detailed description of the duties of MESA in this regard can be obtained by writing to the Assistant Administrator for Metal and Nonmetal Mine Health and Safety.

C. 2031A Dear General Gribble: This is in response to your letter dated March 18, 1975 requesting my comments to your report to Congress on the National Dam Inspection Program authorized by Pub 1ic Law 92-367• The State of New Hampshire presently has the authority and is regulating the construction, inspection, and operation of all non-federal dams. The New Hampshire Water Resources Board is administering all dam statutes and is presently conducting an active inspection program of all dams under the State's jurisdiction. Present State law and established criteria has basically the five regulatory functions as mentioned in your report. I am in basic agreement with your recommendation in that the health, safety and welfare of all State's citizens should be protected by adequate safeguards in dam construction, inspection and proper operation; but I would like to strongly emphasize that each state should have final authority and jurisdiction in any recommended legislative programs to Congress. Not having received Appendix D, Recommended Guidelines for Safety Inspection of Dams, I must make a reservation on a total approval of your recommendations as there may be procedures in the guidelines which are inconsistent with State law, established criteria and practices in the State. I concur with the resolutions adopted by the two national conferences of the Engineering Foundation recommending that the States be provided Federal financial assistance for the initiation and implementation of the dam safety programs. This cost-sharing by Federal authorities with States would be an added incentive to establish a suitable dam inspection program. My office would participate in a meeting with representatives from the Corps to discuss and review your recommended safety standard guidelines in relation to existing State laws and criteria.

Gribble, Jr. Chief of Engineers Department of the Army Office of the Chief of Engineers Washington, D.C. 20314 Dear General Gribble: Your 18 March 1975 letter requests Garments on the text of your report to the Secretary of the Amy on the National Program of Inspection of Dams authorized by Public Law 92-367. It is my position that the prosecution of a dam safety program for all non-federal dams is a state responsibility. Accordingly, I cannot concur in the concept that private developments on federal lands are ultimately the responsibility of the agency holding the land (see last paragraph, page 12 of text and recommendation (d), page 19). In New Mexico anyone proposing to construct structures to utilize public waters, regardless of location, must obtain a permit frcm the State Engineer before commencing construction and by law the State Engineer is responsible for insuring the public safety as it may be endangered by such works. Of course, this is not to preclude a cooperative effort between federal agencies and the State of New Mexico to insure the safety of dams. Except as noted above, I concur with your recommendations. Please feel free to call on me or S. E. Reynolds, New Mexico State- Engineer if you should desire further information. Liii DEPARTMENT OF THE ARMY OFFICE OF THE CHIEF OF ENGINEERS WASHINGTON, D.C. 20314 REPLY TO ATTENTION OF: DAEN-CWE-D 21 April 1975 Honorable Jerry Apodaca Governor of New Mexico Santa Fe, New Mexico 87503 Dear Governor Apodaca: I thank you for your letter of 31 March 1975 regarding my report on the National Program of Inspection of Dams. Your letter and this reply will be appended to the report as submitted to the Secretary of the Army. We agree that New Mexico has jurisdiction over the utilization of public waters and the authority to require a permit from the State Engineer before constructing a dam or impounding water on lands under Federal jurisdiction. We believe, however, that the Federal Government has the primary responsibility to insure that Federal lands are not utilized in a manner detrimental to the public's safety. I believe we can agree that such hazards could develop in those cases where States do not have an adequate dam safety program and the appropriate Federal agency neglects its responsibility in this regard. As you suggest, a cooperative effort between Federal agencies and the States to promote the safety of private dams on Federal lands would be appropriate and desirable.

Sincerely yours Liv Hugh L. Carey Governor State of New York Executive Chamber Albany 12224 April 18, 1975 Dear General Gribble: Thank you for your letter of March 18th enclosing your report on the National Dam Inspection Program. New York State recognizes the importance of the regulation and inspection of dams as they relate to public safety. The State has had dam safety laws dating back many years. Under existing statutes we have carried out, and are continuing to do so, a detailed review process involving the construction and recon¬ struction of dams. In addition, we have a program for the periodic inspection of existing dams in order to discover and correct conditions that might constitute a hazard to public safety. In comparing this State's existing program to the proposed national program, we find there is a great difference in the size limits of dams that are subject to inspection and regulation. We currently have approximately 7,000 dams in the State subject to regulation and inspection. Under the proposed national program, only 770 of the larger dams would be subject to such regulation and inspection. I am asking our Department of Environmental Conservation to review the National Dam Inspection Program as it relates to current staff capabilities, as well as to assess the impact of such a program on future staffing needs. The Department will be contacting your office shortly with additional comments. It is our intention to follow closely the reactions to the national program and to work closely with the various Federal agencies that can offer assistance in this field.

It certainly would prove beneficial if it could be implemented. It does, however, seem that even though the program as outlined is well founded that there would be some problems relative to financing and carrying out the program at this time without some very careful consideration on cost sharing provisions.

We appreciate the opportunity to review and comment prior to the transmittal of the report to the Secretary of the Army. The conclusions and recommendations, drawn on pages 16-17, are items which we do endorse as matters of governmental concern and jurisdiction, particularly in light of the most revealing figures gathered in the inventory. As indicated previously, the position of the State of Washington is one which favors a concept of shared responsibility between the states and the federal government, with the role of each clearly defined in enabling legislation. We maintain that state responsibility should prevail relative to nonfederal structures, and to the extent legally practicable on intrastate streams. Further, we would reiterate our previous position that adequate financing must be available to both state and federal authorities charged with admin¬ istering the program if it is to be effective. For the State of Washington to update and fully implement its existing statutes, some financial assis¬ tance would be helpful if not absolutely necessary. No less assurance should be provided to federal agencies owning or operating dams including the Federal Power Commission interest in licensed projects. We would suggest that one federal agency be given the responsibility for over¬ all program coordination and to provide liaison with the states in procedures and inspection results made at the federal level within each state.

Gribble, Jr. Lieutenant General, USA Chief of Engineers DAEN-CWE-D Office of the Chief of Engineers Washington, D. C. 20314 Re: National Safety of Dams Program P.L0 92-367 Dear General Gribble: With reference to your letter of 18 March 1975, requesting comments on the text of your report concerning the National Safety of Dams Program, we have the following to offer. In August of 1974, the states and various organizations were requested to review the July 1974 draft of the proposed inspection guidelines. At this time it is unknown what consideration was given to these comments. Therefore, our following remarks may or may not be complete. As you have mentioned, the states should have jurisdiction over dams within their boundaries except for federally owned dams or those on federal land. The apparent problem with this is the privately owned dams located on federal land could in some cases be required to use construction or repair techniques far more severe than any imposed by the states. This could only result in creating an adverse economic situation for these private owners. Assuming the September 1974 suggestion of the Western States Water Council to reinstate the paragraph: "...in cases where the hydrologic, hydraulic or stability criteria outlined herein conflict with criteria established by the state in which the dam is located, the state requirements shall pre¬ vail in safety evaluations of non-federal dams unless directed otherwise by the Governor." LXV page twc W. C. Cribble, Jr., Lt. Gen. USA April 16, 1975 was hollowed, then control of the privately owned dams on federal lands should be made to fall under state jurisdiction. It is realized that many states do not have adequate Safety of Dams laws. This serves to justify your idea that, "...safety must be evaluated in light of peculiarities and local conditions." The criteria used for inspections must be considered on a state by state basis. This state’s sparse population should not be made to conform with the more stringent controls necessary in the heavily populated states. Your cost projection of $5,000 to $10,000 per dam for Phase I inspections of high hazard dams causes me to wonder what- the cost of the highly technical Phase II might be. The performing of the National Safety of Dams inspection program and instigation of follow on programs by the states is, in fact, going to be quite expensive. In view of the development costs, most states' follow on Safety of Dams programs may take some years to become even partially active. The end result of the inspection program may in most cases provide an owner with an expensive repair bill. There should then be some consideration of providing this person with a means of financing at low interest rates. Without such a plan numerous owners will be in the position of trying to ignore a state directive to repair their dams, or placed in a very difficult financial situation. This would be a very serious problem for the states and the nation. In the cases where federal law could far exceed state laws, private owners on federal land might have no other choice than to sell or abandon their dams and livelihoods. Thank vou for the opportunity to review your text prior to submittal to the Secretary of the Army and the Congress. With best wishes, EH:d ta cc : George L.

Copies of your letter and this reply will be appended to the report as submitted to the Secretary of the Army. In formulating the recommended inspection guidelines careful attention was given to all comments received on the July 1974 draft. We recog¬ nized that some States may have established or will adopt inspection criteria incongruous in some respects with the guidelines and, therefore, we included in the Preface a statement that in such cases assessments of dam safety should recognize State requirements as well as guideline recommendations. This should create no problem in those instances where guideline recommendations are more stringent than State criteria because evaluation factors of the guidelines are intended to be flexi¬ ble and are presented principally as reasonable basis for assessing existing conditions. The major objectives of the guidelines are to outline principal factors to be weighed in determining existing or potential hazards and to define the scope of activities to be undertaken in safety inspections. The establishment of rigid criteria is not intended. In regard to the question of jurisdiction over private dams located on Federal lands, we believe that the Federal Government has a primary responsibility to insure that Federal lands are not utilized in a manner detrimental to the public's safety. I believe we can agree that such hazards could develop in those cases where States do not have an adequate dam safety program and the appropriate Federal agency neglects its responsibility in this regard. A cooperative effort between Federal agencies and the States to promote the safety of private dams on Federal lands would appear appropriate and desirable. Lxvii DAEN-CWE-D Honorable Ed Herschler 6 May 1975 The total impact of the recommended program on the economic resources of the Nation cannot be accurately assessed at this time. The informa¬ tion needed for such a forecast can be developed only by the inspection program. Recognizing that the costs of necessary in-depth studies and modifications to eliminate hazardous or potentially hazardous conditions may be substantial, the program benefits such as reductions in loss of life and property and minimization of social disruption and human suffering make a compelling case for implementing the recommended dam safety program. Your comments are very much appreciated. Two copies of the complete report, with Appendixes, will be furnished the State of Wyoming when the report is submitted to the Secretary of the Army.

BOX 4267 G.P.O. 00936 CABLE ADDRESS PRWRA April 8, 19 75 Lieutenant General W. C. Gribble Chief of Engineers Department of the Army Washington, D. C. 00910 Attention: DAEN-CWE-D Dear General Gribble: Your letter dated 18 March 19 75 addressed to the Honorable Rafael Hernandez Col6n, Governor of Puerto Rico, on the National Dam Inspection Program authorized by Public Law 92-367 accompanied by two copies of the text of your report to the Secretary of the Army has been referred to my office for review and comment. As you know, the Puerto Rico Water Resources Authority, a public corporation is the government instrumentality which has planned, constructed and operated nearly all, to be more specific twenty (20) of the 25 existing dams in Puerto Rico. These dams were originally intended for the utilization of water resources on the Island and served the three- * fold purpose of being sources of water supply and for irrigation for the generation of hydroelectric energy and for flood control. The other five remaining dams are being utilized and operated by the Aqueduct and Sewer Authority of Puerto Rico, another Commonwealth of Puerto Rico Government agency. As far as we know, any dams that may be planned and constructed in the future will be controlled and operated by the Commonwealth Government. At present we have a program for the inspection and maintenance of dams as explained in our letter to Major General D. A. Raymond, U. S. A. copy of which is enclosed herewith. This program has been carried out with very limited funds. Additional funds will be required to implement all aspects of the program on a more thorough basis and regularity. We have examined carefully the text of your Report to the Lxix General Gribble -2- April ,1975 Secretary of the Army on the National Program of Inspection of Dams and have found it very thorough and completely adequate in all phases covered. We would like to offer our comments on the subject of Responsi¬ bility for Supervision of Program as detailed in Paragraph II of Volume 1 of your report. Since our group of dams fall into the class covered by sub-paragraph c Non-Federal Dams as discussed on page 13 of said report, where it is stated that: "All dam owners, whether public of private interests, have the ultimate responsibility for safe structures and such responsibility needs to be adequately defined by State Legislation". It has been the intention of our Commonwealth Government to institute such legislation, but thus far it has not become possible due to certain limitations of economic nature. Up to now the inspection and mainte¬ nance of these hydraulic structures has been done as one of the many functions of our regular maintenance program, although we have had the technical assist¬ ance of trained personnel provided by the U. S. Bureau of Reclamation. It is my intention to recommend that the necessary legislation covering a program of dam safety be enacted and am looking forward to examine the USCOLD Model Law for State Supervision of Dams and Reservoirs (Appendix C) whenever this becomes available to help us in the preparation on the proposed legislative matters. 12. Cost of Program - We are in complete agreement as to the assumptions shown in your report concerning the cost of the program. 13 . Impact of Program - a) Technical Capabilities - The Commonwealth's Puerto Rico Water Resources Authority is confronted at present, with a shortage of qualified engineers in the design, construc¬ tion and operations of dams. What mostly concerns us today is the outcome of in-depth studies resulting from the initial inspection where the engineering of remedial works may become imperative. 15 . Financing of Program b) State Activities - The Commonwealth of Puerto Rico will be among the number of States that would face difficulties in allocating the funds, if not the technical Lxx 4 General Gribble -3- April 8, 1975 personnel, needed for their share of a national dam safety program as contemplated in your report. We strongly support your idea for incentives to be provided by the Federal Government to the States to implement their share of a national dam safety program. These incentives could be as grants from the Government through the proper Agencies, or as a low-interest, long-term loans to these States which lack the neces¬ sary economic resources. 16. Conclusions a) General The conclusions in General are most realistic and encompass the entire program in all aspects, which are of great and varying degrees. b) Safety Program The concepts as defined in (1), (2) and (3) are most adequate and we doubt that they could be improved in their extent. Same goes for sub-paragraph c on Supervision. 17. Recommendations - We are all whole heartedly in agreement with your recommendations from a to e. We would, however, like to suggest that a sentence be added at the end of paragraph c indicating that funds should also be assigned for financial aids to the States and the Commonwealth of Puerto Rico.

USA Chief of Engineers Department of the Army Office of the Chief of Engineers Washington, D. C. 20314 Dear General Gribble: We share your concern for the safety and welfare of our citizens and agree that the protection of human life and property from potential hazards created by dams and the water they impound is a governmental responsibility. The heavily populated central and northern portions of Guam have no streams with usable reservoir sites. The Navy's Fena Valley Reservoir is located on federal property in southern Guam. There are no developments downstream from the reservoir at this time, however, there are plans for subdivision developments in this area and we would want to be assured of the safety of this dam. The Government of Guam plans to construct a reservoir on the Ugum River to supplement the primary source of water supply available from the underground water lens in the north. We have a number of small water supply reservoirs in the south, however, these reservoirs are being phased out as we develop more dependable sources of water supply.

Deputy High Commissioner ADDRESS SAIPAN Lxxiii DEPARTMENT OF AGRICULTURE OFFICE OF THE SECRETARY WASHINGTON. D. C. 20250 Lt. General W. C. Gribble, Jr. Chief of Engineers Office of the Chief of Engineers Department of the Army Dear General Gribble: We appreciate having the opportunity to review and comment on the proposed National Program of Inspection of Dams. Comments from the Forest Service and Soil Conservation Service, as requested in your letters to them, are included in this response. As stated in our earlier letters (latest 11/22/74), we are very concerned with this subject. Agencies in the Department have some association, either past or currently, or some responsibility for more dams than any other Federal agency. We feel that a program is urgently needed to assure the protection of life and property that is or may be located below or adjacent to dams. The proposed program is well conceived and, we feel, establishes the guidelines needed for a sound dam safety program. It is essential that this program be assigned to and controlled by the respective states. It is requested that the proposed program be revised to require that private dams under permit or other right?located on Federal lands, be included in the states area of responsibility. This will provide dam owners and endangered citizens with a uniform approach to dam safety and will permit a complete state program. Federal dams, as described in the P.L. 92-367, should remain the responsi¬ bility of the Federal agency charged with management of the dam. The program should provide for a transfer of responsibilit}?’ from the state when a mutual understanding can be reached between the state and the concerned Federal land managing agency. (This may be necessary when private dams are located in restricted areas or on military reservations). We are concerned with the impact this proposed program may have on the resources of the state governments. This program will tax the financial and engineering resources of states and of the concerned Federal agencies. It is therefore essential that this program provide for a comprehensive implementation plan that establishes time frames, financial arrangements, and provisions for staffing adjustments. Such a plan must recognize both State and Federal problems and needs. April 1 8, 197b Lxxiv Lt. General W. C, Gribble, Jr. 2 Detailed comments on the report are enclosed. This is an important program and we are anxious to see it carried forward to implementation. Please call on us if we can be of further assistance. Sincerely, ROPERT W. LONG Assistant Secretary Enclosure Lxxv Detailed USDA Comments and Suggestions on National Program of Inspection of Dams, Vol. 1. 1. Page 11, item 5 - If Federal agencies are to be charged with regulating non-Federally owned dams, there may need to be major changes made in current agency policy. There are certain situations, for instance, thac of a dam under a privately ovrned easement within a National Forest, in XThich the exercise of regulatory authority could constitute a "taking*1 of private property for which the United States would have to pay just compensation. In order to avoid any legal uncertainties and in the interests of uniformity in this area, it would be preferable that the states exercise regulatory authority over non-Federally owned dams. 2. Page 12, last paragraph - Comment 1 applies to the dams referred to in this paragraph. 3. Page 18, 3rd paragraph, last sentence - This sentence clearly assigns to the states the responsibility for control of dams constructed with technical and financial assistance from the Soil Conservation Service (SCS). We agree fully with this concept. However, this does seem to establish, within the proposal, an apparent conflict. Many private dams constructed with assistance from SCS are installed on Federal lands. The first sentence in this paragraph assigns responsi¬ bility for these dams to the Federal land managing agency. We believe this apparent conflict can best be resolved by assigning responsibility for all private dams to the states, including those located on Federal lands. 4. Page 19, Recommendations - a. A recommendation on program implementation and financing is needed. This will support the discussion on this subject included in the report. b. Recommendation c. - We question if Federal agencies should be authorized to provide "technical assistance" to state governments. This is in conflict with the interest of consulting engineers and, involves Federal agencies directly in what is proposed to be a state program. c. Recommendation d. - As stated in our cover letter, we do not feel Federal agencies should be assigned responsibility for private dams that are located on their lands. The primary responsibility should rest with the state. Lxxvi DEPARTMENT OF THE ARMY OFFICE OF THE CHIEF OF ENGINEERS WASHINGTON. D.C. 20314 6 May 1975 Honorable Robert W. Long Assistant Secretary of Agriculture Washington, D.C. 20250 Dear Mr. Long: I thank you for your letter of 18 April 1975 regarding my report on the National Program of Inspection of Dams. Copies of your letter and this reply will be appended to the report as submitted to the Secretary of the Army. In regard to your request that the proposed program be revised to place in the States' area of responsibility private dams located on Federal lands, we believe that the Federal Government has a primary respon¬ sibility to insure that Federal lands are not utilized in a manner detrimental to the public's safety. Such hazards could develop where States do not have an adequate dam safety program and the appropriate Federal agency neglects its responsibility in this regard. We do, however, agree that the development of a mutual understanding and agreement between the State and Federal land managing agency with respect to safety supervision of private dams on Federal lands would be appropriate and desirable. The total impact of the recommended program on the economic resources of the Nation cannot be accurately assessed at this time. The informa¬ tion needed for such a forecast can be developed only by the inspection program. The impact on economic resources and technical capabilities to perform regulatory functions, including Phase I inspections, is discussed in paragraph 14 of the report. The technical inspection is an essential first step which will provide knowledge upon which each regulatory agency can then plan for an orderly prosecution of necessary in-depth studies and any follow on remedial work. The conflict in paragraph 16c (1) of the report concerning the supervision of privately owned dams, located on Federal lands and constructed with technical and financial assistance from the Soil Conservation Service was corrected. The last sentence of that paragraph was modified to Lxxvii DAEN-CWE-D Honorable Robert W. Long 6 May 1975 except from State jurisdiction those SCS dams under the regulatory jurisdiction of Federal agencies. I thank you for bringing this con¬ flict to our attention. Your comments are very much appreciated. Two copies of the complete report, with Appendixes, will be furnished the Forest Service, Soil Conservation Service and Department of Agriculture when the report is submitted to the Secretary of the Army.

C. 20314 Dear General Gribble: We have reviewed your report, "National Program of Inspection of Dams," and find it very adequate. We have one comment which concerns the paragraph entitled "(1) States." on page 18. There are a number of dams on Indian reservations, constructed by and under the jurisdiction of the Bureau of Indian Affairs, which were funded under the same authority as those funded by the Soil Conservation Service. These dams are subject to inspection under criteria prescribed by the Soil Conservation Service. We, therefore, suggest that on page 18, in the paragraph entitled "(1) Statesin the last sentence after the words, "Soil Conservation Service," and before the word, "should," the words "except those under the regulatory jurisdiction of Federal agencies," be inserted.

Chief of Engineers Lxxx United States Department of the Interior BUREAU OF RECLAMATION WASHINGTON, D.C. 20240 IN REPLY REFER TO! 510.2 430 APR 181975 Lieutenant General W. C. Gribble, Jr., USA Chief of Engineers Office of the Chief of Engineers Department of the Army Washington, D.C. 20314 Dear General Gribble: This is in response to your letter of March 18, 1975, requesting comments on the Corps of Engineers' report entitled National Program of Inspection of Dams, volume I. We have reviewed the report and our comments are as follows: 1. Paragraph 5, page 2—The report indicates that the lack of adequate funding was an instrumental factor in the decision not to inspect non-Federal dams. We believe it is extremely important that all dams in the United States be inspected, either by the Federal or State governments, and that the inspections be accom¬ plished within a reasonable time frame. We realize that new authorizing legislation would be required to accomplish inspections of non-Federal dams not performed by the States. 2. Paragraph 5, page 3, first sentence—The reference to section 233 of Public Law 92-367 seems to be in error. Also, we suggest iden¬ tification of the agency responsible for the inspections and appraisals of the coal mine refuse banks and impoundments. 3. Paragraph 9, page 9—We are in complete agreement with the need for a national program for the inspection and regulation of dams in the United States. The last sentence, first paragraph, page 8, indicates the probable need for revision of the program guidelines on the basis of experience. Statements on pages 17 and 19 indicate that most State programs and some Federal programs are deficient and that a unified approach to the safety of dams problem is needed. To ensure the expeditious accomplishment of a national program of inspection of dams, we believe authorizing legislation providing authoritative coordination or supervision is needed. Attached is a list of comments and suggestions directed toward such legislation. Lxxxi 4. Paragraphs 10c, page 11; 12, page 14; and 17e, page 19—We interpret the proposed inspection guidelines to require phase I inspections for only those dams in the potentially high-hazard categories. The "Inventory of Dams" required hazard classification but did not provide for field inspection to determine that classi¬ fication. The referenced paragraphs indicate that subsequent inspections will not include dams currently in a low-hazard classification, unless the dams are reclassified to a higher risk category in a subsequent inspection. We recommend that the report include a requirement for periodic field review of the hazard potential of all dams, including those initially determined to be in the low-hazard classification. 5. Paragraph lib, page 12, first partial paragraph—The statement regarding Reclamation dams should read, "... dams under the jurisdiction of the Bureau of Reclamation, . . . ." 6. Paragraph 15b, page 16—The report recognizes the possible need for incentives to encourage the States to implement their share of a national dam safety program; however, the report does not define incentives. Paragraph 13, page 14, suggests that the real incentive is provided the Federal Government rather than the States by the potential reduction of the need for Federal disaster assistance. It is questionable whether the States will support a program that does not provide them with adequate incentives. 7. Paragraph 17c, page 19—We concur in the recommendations that qualified Federal agencies should be authorized to furnish technical assistance and guidance to the States. Also, we believe that it would be appropriate for the Bureau of Reclamation to assist other Department of the Interior agencies. In either case, agreements with Reclamation to provide assistance would need to include con¬ sideration of additional staffing and funding. Sincerely yours Commissioner Enclosure Lxxxii COMMENTS AND SUGGESTIONS CONCERNING A COMPREHENSIVE, CONTINUING NATIONAL DAM SAFETY PROGRAM 1. A need exists for a comprehensive, continuing national program for dam safety. 2. A Federal office should be established for implementing a comprehensive, continuing national program. 3. The Federal office should have a relatively small but highly qualified staff to review periodically the effectiveness of the dam safety program of each State and Federal agency having dams under its jurisdiction. 4. Federal legislation should establish the functions, respon¬ sibilities, and authority of the Federal office for dam safety. 5. If the functions of the Federal office for dam safety are assigned to an existing Federal agency, there should be established in that agency a separate office or division for the purpose of performing those functions. 6. Federal legislation should provide general procedures and authority for the Federal office for dam safety to require corrective action when significant deficiencies in a State or Federal agency program are discovered. 7. The Federal office for dam safety should not be required to inspect and investigate dams, except to determine whether the State or other Federal agency has adequate procedures for such inspections and investigations. 8. A primary function of the Federal office for dam safety should be the development, dissemination, and updating of efficient and effective technical procedures for the various phases of safety inspection and investigation of existing dams. Expertise of the Bureau of Reclamation, the Corps of Engineers, engineering associa¬ tions, and State engineers should be utilized in the development of the technical procedures and implementing guidelines. Such procedures should provide adequate, practical criteria for use in the proper surveillance and evaluation of the structural, hydro¬ meteorological, hydraulic, seismic, operational, and maintenance aspects of all types and sizes of existing dams. 9. Another primary function of the Federal office for dam safety should be the development of national codes for the design and construction of dams and of guidelines for their adoption. In the development of the codes and guidelines, the ideas, opinions, and suggestions of the various Federal, State, and private interests having expertise in these technical fields should be solicited and Lxxxiii considered. The principal purpose of the codes should be to provide (for engineering entities involved in the design and construction of dams) minimum specifications essential for the safety of the structures in regard to materials, structural and hydraulic design criteria, hydrometeorological and seismic design procedures, and construction control. 10. An essential aspect of a comprehensive, continuing national program for dam safety is that each State be required by Federal legislation to establish and support an adequate staff for effective surveillance of dam safety procedures in the design, construction, operation, and maintenance of dams in the States. Each State should be required to adopt a minimum national code or an equivalent for the surveillance of design, construction, and operation and maintenance of dams. Lxxxiv REPLY TO ATTENTION OF: DAEN-CWE-D DEPARTMENT OF THE ARMY OFFICE OF THE CHIEF OF ENGINEERS WASHINGTON, D.C. 20314 9 May 1975 Honorable Gilbert G. Stamm Commissioner of Reclamation Department of the Interior Washington, D.C. 20240 Dear Mr. Stamm: I thank you for your letter of 18 April 1975 regarding the Chief of Engineers report on the National Program of Inspection of Dams. Copies of your letter and this reply will be appended to the report as submitted to the Secretary of the Army. The citation of Public Law 92-367 on page 3, paragraph 5 of the report is in error and will be corrected to Public Law 91-611. I thank you for bringing this to our attention. The field inspections of the coal mine refuse banks and impoundments were conducted by the Corps of Engineers in cooperation with State agencies and other appropriate Federal agencies. A board of review consisting of all participating agencies evaluated field inspection data. This board maintained liaison with the U.S. Department of the Interior Task Force for Studying Coal Waste Hazards. As indicated in those portions of the report cited in paragraph 4 of your letter, Phase I inspections are contemplated for the potentially high hazard and significant hazard categories of dams. This is not in conflict with paragraph 2.2 of the recommended inspection guidelines which provides that the inspection of dams possessing a hazard potential classified high or significant should be given first and second priorities, respectively, in the inspection program. The guidelines also recognize the necessity for reclassification of dams as additional information becomes available. The statement in the report regarding Reclamation dams will be revised as you suggest in paragraph 5 of your letter. Lxxxv DAEN-CWE D Honorable Gilbert G. Stamm 9 May 1975 With respect to your comments on program incentives, one incentive for the Federal Government is the potential reduction of the need for Federal disaster assistance. Other incentives for both Federal and State Governments, for which a monetary value cannot be accurately assigned, are the reductions in loss of human life and property and minimization of social disruption and human suffering due to dam failures. Your interesting comments concerning a Federal office for dam safety and other aspects of our report are very much appreciated.

The opportunity to review and comment on this important and timely program is appreciated. The U.S. Geological Survey agrees that criteria, standards, and regulations should be established so that the public and national interest is pro¬ tected. Your proposed program is a most logical first step toward that goal. The program, as presented in Volume 1, was reviewed by our Engineering Geology Branch and Conservation Division.

We have been pleased to collaborate with you in prepar¬ ing the inventory of those dams under license by the Federal Power Commission and those for which application for license has been filed. We have provided our comments on your pro¬ posed guidelines. We had only two significant comments on your last draft as contained in our letter of October 10, 1974. Those dealt with the size of the flood to be used for spillway adequacy evaluation and the consideration to be given to upstream flood control reservoirs„ I am sure you have given careful consideration to these comments. It is to be hoped that all Federal agencies involved in the supervision of design, construction, operation and main¬ tenance of dams could agree on the key standards of size classification, hazard potential classification, hydrologic evaluation guidelines and factors of safety. Having agreed among ourselves we would be better able to encourage the use of a uniform code of standards by the states and private firms. We recommend that your report to the Congress include a specific recommendation to this effect. t>~ Lxxxix -2- 4 We have one minor comment on your report. The title of paragraph lib. "Federal Dams" should preferably be "Federally Owned or Regulated Dams." Perhaps 15 percent of the 5,500 dams stated as being in this category are those licensed by the Federal Power Commission, but privately owned and operated. Again in paragraph 12, the 5,500 "Federal dams" should be changed to "Federally owned or regulated dams." We concur in and support the conclusions and recommenda¬ tions of your report. xc DEPARTMENT OF THE ARMY OFFICE OF THE CHIEF OF ENGINEERS WASHINGTON, D.C. 20314 REPLY TO ATTENTION OF: DAEN-CWE-D 7 May 1975 Mr. T. A. Phillips Chief, Bureau of Power Federal Power Commission Washington, D.C. 20426 Dear Mr. Phillips: I thank you for your letter of 10 April 1975 regarding my report on the National Program of Inspection of Dams. A copy of your letter and this reply will be appended to the report as submitted to the Secretary of the Army. Your comments of 10 October 1974 on the proposed inspection guidelines were given careful attention during the formulation of the present draft. Paragraph 4.3 was revised to include the need for an assessment of the impact of upstream flood control projects on peak flows or hydrograph analyses. However, we have retained the hydrologic evaluation guidelines listed in Table 3 of the July 1974 draft. The classifications of (1) small dams with high hazard potential, (2) intermediate dams with significant hazard potential and (3) large dams with low hazard potential represent a transition from the low risk combination of size and hazard potential, where a maximum flood of 1/2 PMF is recommended, to the high risk com¬ bination calling for the full PMF. We feel the recommended range of 1/2 PMF to PMF for these classifications provides the desired flexibility for selecting a flood size commensurate with the involved degree of risk at a specific project. We share your hope that all Federal agencies will agree on the prin¬ cipal provisions of the inspection guidelines. Although the recommended guidelines represent the consensus of the agencies and engineering organizations that reviewed and commented on the previous two drafts, we believe that as experience is gained with their use additional revisions will be needed. Thus a continuing updating effort is foreseen. As you have noted, our report uses "Federal Dams" to refer to all dams in which the Federal Government has a substantial interest. We believe xci DAEN-CWE-D Mr. T. A.

" We endorse the overall concept of a comprehensive National Dam Safety Program as outlined generally in the report. In commenting to General Morris on September 27, 1974, concerning the inspection guidelines, we suggested that they should be more flexible. We are glad to see that section 8 of the report now supports this viewpoint by pointing out that the guidelines "do not establish rigid criteria or standards but rather provide guidance on the scope of investigations. . . " and that they must be applied using competent, experienced engineering judgment. One additional comment concerns coal mine refuse piles and settling pond dikes which create impoundments incidental to their main function. Evidently the report considers these in the same category as dams which are engineered structures. It would seem advisable to treat x’efuse piles and dikes separately.

AUTHORITY This report is in response to Section 5 of the National Dam Inspec¬ tion Act (Public Law 92-367), approved 8 August 1972, which reads as follows: "Section 5. The Secretary shall report to the Congress on or before July 1, 1974, on his activities under the Act, which report shall include, but not be limited to - (1) an inventory of all dams located in the United States; (2) a review of each inspection made, the recommendations furnished to the Governor of the State in which such dam is located and information as to the implementation of such recommendation; (3) recommendations for a comprehensive national program for the inspection, and regulation for safety purpose of dams of the Nation, and the respective responsibilities which should be assumed by Federal, State and local governments and by public and private interests." 2. INTERIM REPORT A progress report on the activities authorized by Public Law 92-367 was furnished to the Congress by letter dated 24 July 1974. That letter reported the status of work on the dam inventory; the survey of State and Federal agencies' practices, capabilities and regulations concerning dam safety; and the guidelines for the safety inspection of dams. 3. SCOPE The activities performed under the program authorized by Public Law 92-367 have consisted of: (a) compiling the data for an inventory of Federal and non-Federal dams; (b) conducting a survey of each State and Federal agency's capabilities, practices, and regulations in regard to the design, construction, operation and maintenance of dams; (c) developing guidelines for the safety inspection and evaluation of dams; and (d) formulating recommendations for a comprehensive national pro¬ gram including the respective responsibilities which should be assumed by Federal, State and local governments and by public and private interests. This report submits the results of these activities. 1 4. BACKGROUND The Dam Inspection Act (P.L. 92-367) was enacted in the wake of several catastrophies due to dam failures and reflects the great concern of the public about dam safety. These events were the failures of the Canyon Lake Dam at Rapid City, South Dakota and the mine refuse embank¬ ment at Buffalo Creek, West Virginia. Also, the June 1972 hurricane named Agnes caused extremely heavy rainfall in the Northeastern region of the country resulting in unprecedented flooding which posed a serious threat to a large number of dams, some of which were overtopped or damaged, adding to the property damage otherwise caused by the flooding and further adding to the public's concern. While the safety of dams and the consequences of failure of a dam or the untimely release of its reservoir contents have previously been a concern of several States, Federal water resources agencies and national professional engineering societies, no Federal study of this problem has previously been conducted on a national scale. The only previously known study of States' practices and regulations pertaining to the construction, operation and maintenance of dams was conducted in 1965 by the United States Committee on Large Dams (USCOLD). The United States Committee on Large Dams, a member of the International Commission on Large Dams, is an organization of professional engineers, geologists and individuals and organizations concerned with the design, construction, operation and maintenance of dams and embankments for the impoundment of water. The published report "Supervision of Dams by State Authorities" did not cover the practices and regulations of the Federal agencies having dams under their jurisdiction. The report indicated that 27,914 dams were under the control of State authorities and that the supervision of dams was not exercised by all States. It further indicated that there were many differences and inadequacies in the manner in which the States were carrying out their responsibilities to the public for the safety of dams. 5. INSPECTIONS While the authorizing legislation provided for the inspection of non-Federal dams, no inspections have been performed due to limited funding and the belief that such inspections should be accomplished by the concerned States as part of their normal responsibilities. However, consistent with Corps of Engineers past practice, technical assistance and advice regarding measures to eliminate or mitigate hazardous conditions found by others have been given in response to 127 requests since implementation of the Act. The Corps has also responded to 10 requests for assistance in developing or strengthening State dam safety programs. *■ 2 In addition, inspections and appraisals of coal mine refuse banks and impoundments have been made in the Potomac, Susquehanna, Delaware and Ohio River basins in specific response to the 28 February 1972 Resolution of the Senate Committef on Public Works and were funded under the Strip Mine Study authorised by Section 233 of Public Law 91-611. These inspections have been completed at a total of 495 sites in Ohio, West Virginia, Virginia, Kentucky and Pennsylvania. Of these, 30 were classified as critically hazardous and 172 potentially hazardous, all requiring some corrective action. Where hazardous mine waste impound¬ ments have been identified they have been immediately reported to the concerned mine owners, State Governors and Federal agencies for corrective action. The necessary remedial work is the responsibility of the mine owners and is monitored by the States or the Mining Enforcement and Safety Administration of the Department of the Interior. 6. INVENTORY OF DAMS The National Dam Inventory included in Appendix F of this report con¬ tains data on approximately 49,000 dams, in the 50 States and 4 Terri¬ tories, which are 25 feet or more in height or have a maximum impounding capacity of fifty acre-feet or more. In conformance with Public Law 92-367 dams not in excess of six feet in height, regardless of storage capacity, or which have a storage capacity at maximum water storage elevation not in excess of fifteen acre-feet, regardless of height, are excluded from the inventory. The inventory data for non-Federal dams were obtained under direct State supervision in 37 States or Territories and in 14 others by private engineering firms under contracts with the Corps of Engineers. In the remaining 3, the Corps developed the inventories in-house. The inventory data for dams under the jurisdiction of Federal agencies and dams licensed by the Federal Power Commission were compiled by the Federal agency having jurisdiction over the dams and were furnished to the Corps of Engineers for inclusion in the national inventory. Where data on Federal dams were lacking, the States and private engineering firms collecting the data for non-Federal dams were contracted to obtain the supplemental information. The data were collected using the two part inventory form contained in Appendix F. All items of Part I of the inventory forms were obtained for each dam inventoried and only the items of Part II which were readily available were obtained. All data have been stored on magnetic tape in a master file for easy access and use by all interested agencies and organizations. The inventory data consist of the name of the dam or impoundment; the river or stream on which the dam is located; the type of dam; year completed; purpose of the dam; the height and maximum storage capacity; the name, population and distance from the dam to the nearest downstream city, town or village; the downstream hazard potential; 3 the owner of the dam; and the Congressional District in which the dam is located. The Governor of each State has been furnished a copy of that portion of the inventory containing the data for dams within his State. The inventory data indicate that only 18% of the dams have been inspected under existing State or Federal authority. The downstream hazard potential indicating potential loss of life or property resulting from failure of the dam or mis-operation of facilities has been recorded for 76% of the dams inventoried. Fifty (50) percent of the dams inven- toried are classified as having a low downstream hazard potential, with 11% having a high hazard potential and 157. having a significant hazard potential. No information is recorded on the hazard potential at the remaining 24% of the inventoried dams. 7. EXISTING REGULATORY FUNCTIONS AND PRACTICES To aid in formulating the recommendations for a comprehensive dam safety program, a questionnaire survey was made to learn each State and Federal agency's capabilities, practices, and regulations regarding the design, construction, operation and maintenance of dams. a. State Authorities All 50 States and 3 Territories responded to the questionnaire on Supervision of Dams by State Authorities. A tabulation of these responses is contained in Appendix A. The responses indicated that 11 States and Territories have no laws regarding any aspect of dam supervision. The legislative authority of many of the others is considered inadequate from the standpoint of establishing all activities necessary for dam safety. Twenty-four (24) indicated that their current dam safety regulations do not fully meet present needs and 20 stated that they have active plans to modify existing regulations. Forty-one (41) States and Territories require a permit or license to be issued prior to construction of a private dam; 36 require the review of plains and specifications prior to construction; and 23 provide on-site inspection by State personnel during construction. Thirty-two (32) States have authority to perform safety inspections after construction; however, in most cases firm schedules are not maintained. Many perform an inspection only when information is received that a hazardous condition might exist or under other special conditions. The responses further indicated that 54,195 dams are under State supervision and that $4,371,379 is the determinable approximate annual 4 budget of the State authorities directly related to dam and reservoir supervision. This number of dams is larger than that included in the inventory because in some cases State regulations encompass impound¬ ments which do not meet the Public Law 92-367 definition of "dam." There are great differences among the States in carrying out their responsibilities to the public for the safety of dams built within their jurisdictions. Many have inadequate statutes and others have inadequate staffs to enforce the statutes. Few States, if any, including those with adequate dam safety regulations, are prosecuting a program com¬ parable to that recommended in this report. Principally, this is due to the lack of funds and staff to perform inspection duties. It is apparent that increased activity in the regulation of the design, construction, operation and maintenance of dams is required and desired to protect life and property from potential hazards created by dams. b. Federal Agencies Twelve (12) agencies responded to the questionnaire on Supervision of Dams by Federal Agencies. A tabulation of these responses is contained in Appendix B. Three Federal agencies have regulatory authority over non-Federal dams. These agencies are the Federal Power Commission, the Corps of Engineers and the Mining Enforcement and Safety Administration of the Department of Interior. Under authority of the Federal Power Act the Federal Power Commission supervises the design, construction, operation and maintenance of dams under its jurisdiction. The Federal Power Act requires the licensing of hydroelectric power plants which (1) utilize surplus water from a Government dam; (2) occupy public lands or reservations; (3) are located on a navigable stream; or (4) produce energy which is transmitted across State lines, thus affecting inter¬ state commerce. A Corps of Engineers permit is required for those dams that fall under the authority of Section 9 of the River and Harbor Act of 1899. Section 9 of the River and Harbor Act prohibits the construction of any dam or dike across any navigable water of the United States in the absence of Congressional consent and approval of the plans by the Chief of Engineers and the Secretary of the Army. Where the navigable portions of the waterbody are wholly within the limits of a single State, the structure may be built under authority of the legislature of that State, if the location and plans or any modification thereof are approved by the Chief of Engineers and the Secretary of the Army. A separate Corps of Engineers permit is not required for licenses issued by the Federal Power Commission. Under the Corps of Engineers permit procedures, the design of the dam is the responsibility of the applicant. The Corps reviews the applicant's design to insure that good engineering 5 practices are applied. The construction, operation and maintenance of the dam must be in compliance with the permit, however the Corps does not provide direct supervision ov.r these activities. The third Federal agency having regulatory control of non-Federal dams is the Mining Enforcement and Safety Administration (MESA) of the Department of Interior. MESA's authority for dam safety is contained in the 1966 Federal Metal and Nonmetallic Mine Safety Act and the Federal Coal Mine Health and Safety Act of 1969. These Public Laws make MESA responsible for mining operations including water and silt impoundments which may affect the safety of mines. In January 1974 MESA proposed revisions to its regulations to provide additional requirements for the construction and maintenance of new and existing coal waste deposits and water and silt impounding structures to gain maximum assurances that such deposits or structures are stable and will not fail. A public hearing on these proposed changes was held 23 July 1974 in Charleston, West Virginia and the findings of the hearing were published in the Federal Register on 1 November 1974. The final revisions to the regula¬ tions are expected to be published in the near future. The Soil Conservation Service (SCS) provides technical assistance and financial support to local sponsors for the design and construction of dams. The local sponsors own and are responsible for the operation and maintenance of the dams. The operation and maintenance agreements with the SCS require annual and special inspections by the local sponsors, and the Soil Conservation Service participates in these inspections for the first three years after construction. If conditions warrant and the sponsor so requests, the Soil Conservation Service will provide technical assistance in dealing with special operating and maintenance problems. These dams are not Federal dams since the owner¬ ship and responsibility for operation and maintenance rests with the local sponsors after completion of construction. The Forest Service, Corps of Engineers, Bureau of Indian Affairs, Bureau of Land Management, Bureau of Reclamation, Bureau of Sport Fisheries and Wildlife, U.S. Geological Survey, Mining Enforcement and Safety Administration, Federal Power Commission, International Boundary and Water Commission and Tennessee Valley Authority have existing authority concerning the responsibility for safety of dams they own or operate or which are located on lands under their supervision. An exception to this is the case of dams located on lands within the National Forests under privately owned easements for which the Forest Service does not have specific jurisdiction. These Federal agencies discharge their safety responsibilities with varying capabilities and dissimilar manners. In general on-site inspection by agency personnel is required during construction and periodically thereafter. However, three agencies have no definite schedule for periodic inspections. 6 The dams under the jurisdiction of the Bureau of Reclamation, the Ten¬ nessee Valley Authority, the International Boundary and Water Commission and dams licensed by the Federal Power Commission, which are excluded from the inspection requirements of Public Law 92-367, and those owned and operated by the Corps of Engineers are presently being periodically inspected in accordance with existing agency regulations. The responses to the questionnaire further indicate that the deter¬ minable annual budget directly related to dam and reservoir safety supervision by Federal agencies is approximately $5,617,500 and that 16,473 dams, approximately 11,000 of which are not included in the definition of "dam" contained in Public Law 92-367, are under the jurisdiction of Federal agencies. Five (5) of the Federal agencies indicate that their current regulations pertaining to dam safety do not fully meet present requirements and plans are being made to modify existing regulations to improve and strengthen dam safety programs. These agencies are the Bureau of Land Management, Bureau of Sport Fisheries and Wildlife, U.S. Geological Survey, Mining Enforcement and Safety Administration, and the Corps of Engineers (regulations governing dam permits under Section 9 of the River and Harbor Act of 1899). 8. INSPECTION GUIDELINES Recommended technical guidelines for performing safety inspections of dams were drafted to outline principal factors to be weighed in identifying deficiencies and hazardous conditions. They were developed with the assistance of State agencies, other Federal agencies, profes¬ sional engineering organizations, and private engineers. These "Recommended Guidelines" are attached to this report as Appendix D. Since the scope and completeness of each investigation would depend upon the availability and suitability of engineering data, the validity of original design assumptions and the physical conditions at the dam, the guidelines provide for two phases of investigation. Phase I would be an inspection to assess the general condition of the dam and determine the need for any additional engineering investigations and analyses. It would consist of a visual examination of the dam and a review of available engineering data, including operating records. It is not intended that costly explorations or analyses would be per¬ formed during a Phase I inspection. Phase II investigations would be performed where the results of the Phase I inspection indicate the need for additional investigations and studies. Phase II would include, as required, all additional visual examinations, measurements, foundation exploration and testing, materials testing, hydraulic and hydrologic analyses, and structural stability analyses deemed essential to evaluate the safety of the dam. 7 The inspection guidelines do not establish rigid criteria or standards but rather provide guidance on the scope of investigations, both Phase I and Phase II, and present reasonable evaluation factors with which to compare existing conditions. Safety must be evaluated in light of peculiarities and local conditions at a particular dam and in recogni¬ tion of the many factors involved, some of which may not be precisely known. This can only be done by competent, experienced engineering judgement, which the guidelines are intended to supplement and not replace. Conditions found which do not meet guideline recommendations are to be assessed by the investigator as to their importance from the standpoint of the involved degree of hazard. Many deviations will not compromise project safety while others will involve various degrees of risk, the proper evaluation of which will afford a basis for priority of subsequent attention and possible remedial action. As experience is gained with use of the guidelines the need for revisions will become evident and a continuing updating effort is foreseen. The guidelines present only procedures for investigating and evaluating existing conditions. Their scope does not encompass the studies and engineering required for project modifications to correct deficiencies found by the investigation. 9. NEED FOR NATIONAL PROGRAM Any artificial barrier which impounds or diverts water creates a potential hazard to human life and property located downstream. The potential hazard is created by the possibility of a sudden release of the water behind the dam as a result of failure of the dam or mis- operation of the discharge facilities. This ever present potential hazard dictates that dams be properly designed, constructed, operated and maintained to reduce the risk of failure or mis-operation through¬ out the life of the dam. The United States Committee on Large Dams conducted a questionnaire survey of past dam failures (prior to 31 December 1972) within the United States. Results were recently published jointly by the American Society of Civil Engineers and the United States Committee on Large Dams in a report entitled "Lessons from Dam Incidents, USA," 1975, The report lists 39 major dam failures which resulted in complete abandonment of the dam, 37 major failures where the damage was success¬ fully repaired and the dam placed in operation again, and some 104 accidents which were prevented from becoming failures by expeditious remedial work or operating measures, such as drawing down the pool. In addition, some 171 other types of accidents or damages were reported which were considered not to affect the immediate public safety. It has long been recognized that the protection of the health, safety and welfare of its citizens is a governmental responsibility and, 8 therefore, the protection of human life and property from potential hazards created by dams and the water they impound is deemed a govern¬ mental concern. Although the adequacy and safety of dams owned and operated by numerous governmental agencies, public and private organi¬ zations, and private individuals are the obligations of the owners, the need for governmental regulation of some type to insure that the owners' obligations are properly carried out is considered evident. Similar social needs have long been recognized in building codes, elevator inspections, bridge inspections, and many other facets of modern life where governmental regulation has been found necessary to protect the public. A substantial number of Federal and State agencies as well as private engineering organizations agree that a national dam safety program should be implemented. P.L. 92-367 has been the stimulus for two national conferences of the Engineering Foundation (an endowed, non-profit organization which sponsors meetings designed to increase engineering knowledge) and for actions taken at several meetings of interested State organiza¬ tions. Engineering Foundation Conferences of national scope were held during September 1973 on "Inspection, Maintenance and Rehabilitation of Old Dams" and in August 1974 on "Safety of Small Dams." Resolutions adopted by participants at both Conferences emphasized the need for a dam safety program and recommended that such a program be financed on a Federal-State cost sharing basis. Copies of these resolutions are contained in Appendix E. Also in Appendix E are copies of pertinent resolutions adopted by (1) the Association of Western State Engineers at their 47th Annual Meeting on 30 August 1974; (2) the Western States Water Council at a L3 October 1972 Meeting; and (3) the Southern Environmental Resources Conference on 6 June 1974. These organizations support the view that the States should have primary responsibility for the safety of non- Federal dams and recommend that the States be provided Federal financial assistance for the implementation of dam safety programs. 10. ELEMENTS OF A NATIONAL PROGRAM The prosecution of a national dam safety program would require suitable legislation and regulations to define the scope of supervision and authority over dams and to empower designated agencies (Regulatory Agencies) to carry out regulatory functions. These functions would pertain to the design, construction, operation, maintenance, enlargement, modification, removal or abandonment of dams and reservoirs. a. Model Law Following the failure of several large dams in the United States and Europe, the United States Committee on Large Dams (USCOLD) under¬ took a survey of the practices and regulations of the States controlling 9 the design and construction of dams in the United States. Concerned with the apparent lack of adequate supervision of dams revealed by its survey, USCOLD appointed a committee of its members to draft a model law for State supervision of dams and reservoirs. The committee developed the text of a proposed model law which was circulated to the Governors of the 50 States and to other concerned State officials for review and comment. Based upon comments received from 47 States the model law was revised and subsequently printed and distributed in 1970 to the Governors of the 50 States and their respective officials responsible for supervision of dams. The published Model Law for State Supervision of Safety of Dams and Reservoirs which is contained in Appendix C is an excellent example of what is considered adequate legislation covering State authority over the supervision of dams and reservoirs. The USCOLD model law provides for the safety supervision of dams and reservoirs in all stages of design, construction, operation, main¬ tenance, enlargement, modification, removal or abandonment. It was intended that the Model Law be modified as required to fit the needs of individual States. b. Regulatory Functions Based upon the provisions of the USCOLD Model Law and the reported experiences of State and Federal agencies and private engineering organizations, the regulatory agency should perform the following functions to insure the adequacy of dams and reservoirs: (1) Review and approve the plans and specifications to construct, enlarge, modify, remove or abandon a dam or reservoir. The plans and specifications should be supported by engineering data, including design analyses, in sufficient detail to permit the regulatory agency to determine the safety, adequacy and suitability of the proposed action before the action is undertake!!. (2) Perform periodic inspections during construction for the purpose of insuring compliance with the approved plans and specifications. (3) Upon completion of construction, issue a certificate of approval. The owner would be required to submit to the regulatory agency the "as-built" drawings and other construction records such as foundation data and geological features, properties of embankment and foundation materials, concrete properties and construction history for review and approval. Upon approval of data and the determination of the adequacy of the structure, the certificate of approval would be issued permitting the owner to store water. 10 (4) Investigate the dam and reservoir at least every five years to determine their continued safety. The investigations should be detailed, systematic, technical inspections and evaluations to analyze and evaluate the hydraulic and hydrologic capabilities, structural stability and operational adequacy of the project features in order to determine if the dam and reservoir constitute a danger to human life or property. The Recommended Guidelines for Safety Inspection of Dams,contained in Appendix D, present technical procedures for performing safety investi¬ gations . (5) Issue notices when appropriate to require the owner of the dam and reservoir to perform necessary maintenance or remedial work, revise operating procedures or take other actions including breaching of the dam when deemed necessary. The regulatory agency, under the police power of the State, should enforce these notices and when emergencies exist have the work performed under its direction and supervision if the owner fails to do so. c. Initial Inspections Implementation of a periodic investigative program for existing dams would be accomplished by an intensive initial inspection effort. Essentially, this would consist of Phase I inspections to identify expeditiously those dams which may pose a hazard to human life or pro¬ perty. It is believed that a 5-year period would be a reasonable interval in which the estimated 20,000 dams in the significant and high hazard potential categories could be inspected effectively. When the results of the Phase I inspection indicate the need for additional investigations, the owner should be required, under super¬ vision of the regulatory agency, to have the additional investigations, Phase II, performed by qualified personnel. 11. RESPONSIBILITY FOR SUPERVISION OF PROGRAM a. General The division of jurisdiction of the Federal and State governments over the water resources of the Nation has been fairly well defined by existing laws and precedent. Discussion of the supervision of dams is simplified by placing the dams in two broad categories, i.e., Federal and non-Federal dams. In developing recommendations for a comprehensive national dam safety program several alternatives were considered for assigning supervisory responsibility for both Federal and non-Federal dams . 'b. Federal Dams There are approximately 5,500 dams conforming to the height and capacity requirements of Public Law 92-367 in this category. 'These are 11 dams located on lands under the jurisdiction of the Forest Service, U.S. Geological Survey, and Bureau of Indian Affairs; dams owned and operated by the Corps of Engineers and dams otherwise under the jurisdic¬ tion of the Corps of Engineers under authority of Section 9 of the River and Harbor Act of 1899; dams owned, operated and located on lands under the jurisdiction of the Bureau of Land Management; dams under the jurisdiction of the Bureau of Reclamation; dams owned and operated by the Bureau of Sport Fisheries and Wildlife, the International Boundary and Water Commission and Tennessee Valley Authority; dams under the juris¬ diction of the Mining Enforcement and Safety Administration under authority of the 1966 Federal Metal and Nonmetallic Mine Safety Act and the Federal Coal Mine Health and Safety Act of 1969; dams licensed by the Federal Power Commission under authority of the Federal Power Act; and dams located on lands of military installations and Federal prisons. While various alternatives regarding the responsibility for super¬ vising- the safety of Federal dams are available, only one alternative is deemed acceptable and practicable. This alternative would require the Federal agency owning or operating the dam, owning the land on which the dam is located, or which has existing regulatory jurisdiction over the dam to assume the responsibility. Other possible alternatives include (1) the designation of a single Federal agency to regulate all dams under Federal jurisdiction; (2) expansion of the existing regulatory authority of the Federal Power Commission, Mining Enforce¬ ment and Safety Administration and Corps of Engineers to cover all dams under Federal jurisdiction; and (3) assign the responsibility for the program to designated agencies which have the existing expertise and capabilities to conduct the program. The alternative considered most acceptable would assign responsi¬ bility for the dam safety program to the agency most familiar with the structure involved and would require no major shifts of project responsi¬ bilities among the Federal agencies. It would, however, require some revisions of agency administrative procedures and allocations of resources to implement the program. Those Federal agencies currently lacking technical expertise and capabilities to conduct the program could utilize upon request the existing expertise and capabilities of the Corps of Engineers, Bureau of Reclamation or others to assist in the implementation of a dam safety program. Some privately owned dams are located on Federally owned lands. These dams are largely located within National Forest boundaries and occupy Federal lands under various authorities. While the administra¬ tion of private developments on Federal lands generally is in coopera¬ tion with State and local authorities, the ultimate responsibility for public safety on Federal lands would appear to rest with the Federal 12 government. Hence it appears desirable to provide for supervision of such privately owned dams by the Federal agency most concerned. c. Non-Federal Dams The non-Federal dam category includes approximately 43,500 dams and reservoirs conforming to the height and capacity requirements of Public Law 92-367. These dams are owned and operated by numerous State and local governmental agencies, public and private organizations and private individuals and are not under the jurisdiction of the Federal government. In general the protection of the health, safety and welfare of its citizens has been recognized as a State responsi¬ bility in this country. Under this concept, as has been noted, the majority of the States and Territories have enacted laws recognizing the police powers of the State over the regulation of dams. Hence, a national program for dam safety should recognize the primacy of State authority in regulating non-Federal dams and seek to strengthen, not supplant, existing State efforts. Such a goal has been assumed in the recommendations of this report. While some local governmental agencies and public and private organizations may have a technical capability adequate for supervising dam safety, it appears appropriate that the final authority and responsibility rest with the State agency designated by the Governor. Thus the responsibility of local government and public and private interests will be primarily dictated by the legislation of each State. All dam owners, whether public or private interests, have the ultimate responsibility for safe structures and such responsibility needs to be adequately defined by State legislation. Where a State program for dam safety does not exist, one could be adopted by enactment of legislation similar to the USCOLD Model Law for State Supervision of Dams and Reservoirs (Appendix C). Changes in the Model Law to meet constitutional and legal requirements, the organiza¬ tional structure, and financial system of the State would be appropriate. The State regulatory agency would need to be provided with adequate personnel, financing, and powers to enforce its rules and regulations. 12. COST OF PROGRAM The total cost of implementing and prosecuting a national dairi safety program is extremely difficult to forecast because of uncertainties such as total number of dams to be investigated; the depth of investi¬ gations which would be found necessary; the amount of effort which would be involved in licensing and inspecting new construction. 13 including the review and approval of plans and specifications; and the supervision which would be needed in connection with repair and modifi¬ cations. Cost data on the programs of the State of California, the Tennessee Valley Authority, the Bureau of Reclamation and the Corps of Engineers show a wide range of costs and reflect different intensities and frequencies of inspections and different scopes of other regulatory activities. Although no direct cost comparisons can be made between the programs of these agencies and the recommended dam safety program, an evaluation of the available cost experience leads us to believe that the total annual program cost for the 49,000 dams would be about $73,500,000, which represents an average of $1,500 per dam per year. About $65,500,000 would be for the programs covering 43,500 non-Federal dams and $8,000,000 for the 5,500 Federal dams. These costs assume that periodic inspections would be conducted at five year intervals and would be made only for the dams with significant and high hazard potential. We estimate that about 20,000 dams are in these categories with about 9,000 being in the high hazard potential category and 11,000 in the significant hazard potential category. The cost of performing the initial Phase I inspections of significant and high hazard potential dams is expected to range between $5,000 and $10,000 per dam depending upon the dam's size and complexity. Assuming an average cost of $7,500 per dam, the total annual cost of the initial Phase I inspections of significant and high hazard dams should be about $30,000,000 if all these dams are inspected within a five-year interval. About $27,000,000 of this annual cost would be for the inspection of non-Federal dams. These estimates do not include the costs related to extensive in-depth studies, investigations or analyses required to evaluate deficiencies and hazardous conditions found by the regulatory agencies' investigations, nor the remedial work necessary to eliminate deficiencies or hazardous conditions. 13. COST-EFFECTIVENESS OF PROGRAM While it is not possible to demonstrate absolutely that the proposed inspection and regulation program is the most cost-effective solution to the national dam safety problem it appears that it is cost effective. The proposed program would require substantial expenditures; however, we believe that in the long run the program would require less expendi¬ ture than continuation of the status quo. Under present conditions, when a dam failure occurs extensive assistance is necessary in the form of services during recovery operations and in the form of disaster relief payments. 14 It is difficult to ascertain the total cost of disasters such as those which occurred at Buffalo Creek and at Rapid City; but surely the cost is in the tens of millions of dollars, if not in the hundreds of millions. An inspection and regulation program that would virtually eliminate all significant property damage or loss of life should, in time produce benefits (in terms of disaster assistance averted) that would exceed the cost of the program. These benefits, together with other benefits such as reductions in loss of life and property and minimization of social disruption and human suffering, make a compelling case for an inspection and regulation program. 14. IMPACT OF PROGRAM a. Economic Resources As indicated in paragraph 12 the impact of the proposed program on the economic resources of the Nation cannot be forecast at this time. However, as stated above the total annual expenditure of funds to perform regulatory functions only would be about $73,500,000. This sum includes, for the first five years, a recommended $30,000,000 annual expenditure for performing initial inspections of existing dams. The initial inspections would provide a better understanding of the scope and nature of the problem and would develop information upon which an accurate assessment of the impact on the owners of dams, both public and private, could be based. The increased costs to be borne by dam owners would include the additional studies and investigations found necessary by the initial inspections as well as any remedial work. While these expenses may be substantial to correct deficiencies and inadequacies due to past neglect, the impact could be tempered by prudent scheduling and the establishment of priorities based upon the relative degree of involved hazards. b. Technical Capabilities The impact of the proposed program on technical capabilities would be an increasing need for qualified engineers experienced in the design, construction and operation of dams. Based upon California's experience and a cursory review of capabilities of Architect-Engineer firms, a sufficient number of qualified engineers and technicians are available in the public and private sectors to staff adequately the required regulatory staffs and to accomplish the proposed initial inspections of existing dams within a 5-year period. Other needs of the program, including in-depth studies and the engineering of remedial works, are expected to be met by proper scheduling and an expansion of capabilities which would accompany increased experience and demand. 15 15. FINANCING OF PROGRAM As has been noted in responses by State agencies, implementing a national dam safety program as contemplated in this report would involve some financing problems for just the work of inspection and supervision by governmental agencies, neglecting any following costs for remedial work to correct conditions found in inspections. No comprehensive study has been made of the problems in financing inspection and super¬ vision activities. Hence, no recommendations are made in regard to such financing arrangements. Some of the considerations applying to the financing problem are as follows: a. Federal Agencies Several Federal agencies would require additional resources, both in funds and personnel, to implement their share of the national program contemplated in this report. However, once the program is adopted, it appears that each agency could obtain the needed resources through normal budgeting and appropriation procedures. For the Federal agencies having major responsibilities for dam construction and continuing supervision such resources should be adequate to permit, in addition to the implementation or continuation of a safety program for the dams for which the agency is responsible, the furnishing of technical assistance and guidance for State programs upon request. b. State Activities As a number of State representatives have indicated, it appears that some States would face difficulties in allocating the personnel and funds needed for their share of a national dam safety program as contemplated in this report. It may be possible that the proposed State supervision of non-Federal dams could be implemented with funding from the general resources of each State involved augmented perhaps with fees collected from the owner of each dam supervised. However, in light of the indications of funding problems already expressed and the past inaction of many States in the face of recognized dam safety problems, it may be considered desirable to provide incentives to the States to implement their share of a national dam safety program. 16. CONCLUSIONS a. General (1) Past incidents of dam failure have demonstrated that adequate attention has not always been given to the regulation of design, construction, operation and maintenance of dams. 16 (2) While the number of dams which are an actual hazard to human life or property is unknown, estimates based upon incomplete data from the inventory indicate that approximately 40°L of existing dams present a significant or high hazard potential to downstream areas. That is, about 20,000 dams are so located that failure would result in loss of life and damage to homes, buildings, public utilities, highways or railroads. Although only a relatively low number are believed to present a real hazard at this time, a program to identify critical situations and to monitor future developments is deemed essential. Changing condicions due to aging of structures and facilities and growth in downstream areas necessitate that continual surveillance be provided. (3) Dam safety programs in most States and in some Federal agencies having water resources responsibilities are either nonexistent or inadequate. The wide variations in practices, regulations and capabilities of supervising agencies attest to the need for a unified approach to the dam safety problem. (4) The Federal agencies have discharged their responsibilities for the safety of dams under their jurisdiction with varying degrees of effectiveness depending upon technical capabilities and financial resources. Excellent technical capabilities for supervision of dam safety exist with the Federal agencies whose primary respoxisibility is the development of water resources. The capabilities of these water resources agencies should be utilized by other agencies which do not have the same expertise and experience in the design, construction, operation and maintenance of dams. b. Safety Program (1) A dam is a complex structure whose safety and continuing adequacy involve the ability of the structure to interact with its foundation in withstanding applied forces which are dependent upon many variable conditions. A high degree of professional engineering performance is required to insure adequacy of design and construction. To further reduce the risk of failure or mis-operation, continued surveillance of the dam and appurtenant works is necessary to detect conditions of significant structural distress or operational inadequacy and to pro¬ vide a basis for timely initiation of restorative and remedial measures if necessary. (2) Based on past history, recommendations of States and technical societies, and the general public's apprehension as recognized by P.L. 92-367, it is evident that a comprehensive national dam safety program is needed in the United States to provide for consistent regulation of design, construction, operation and maintenance of dams. 17 (3) Authorities should be established to regulate the design, construc¬ tion, operation, maintenance, enlargement, modification, removal or abandonment of dams and reservoirs, and such authorities should be provided with adequate personnel, financing and powers to enforce their rules and regulations and accomplish their regulatory functions. The jurisdiction of regulatory agencies should cover all existing and future dams as defined by Public Law 92-367. These agencies should have authority to perform the five principal functions outlined in paragraph 10b. c. Supervision The adequate design, construction and surveillance of dams require professional engineering services. To insure that competent, professional attention is directed toward the question of dam safety, supervision of the recommended dam safety program should be placed under the jurisdiction of Federal and State agencies. (1) States Each State should have jurisdiction over all dams and reservoirs within its boundaries except for those owned or operated by an agency of the Federal government, those located on lands owned by an agency of the Federal government, and dams under the jurisdiction of (1) the Federal Power Commission under the authority of the Federal Power Act, (2) the Secretary of the Army under Section 9 of the River and Harbor Act of 1899, and (3) the Mining Enforcement and Safety Administration of the Department of Interior under authority of the 1966 Federal Metal and Nonmetallic Mine Safety Act and the Federal Coal Mine Health and Safety Act of 1969. Dams constructed with technical assistance and financial support of the Soil Conservation Service, except those under the regulatory jurisdiction of Federal agencies, should be under the jurisdiction of the States since the ownership and responsibility for operation and maintenance rest with the local sponsor after com¬ pletion of construction. (2) Federal Federal agencies should have jurisdiction over all dams and reservoirs excluded from the States' jurisdiction. d. National Dam Inventory The data compiled in the national dam inventory should be of value in all aspects of water resources development and should prove useful to public and private interests in planning of future developments, utilization of existing water resources, and in emergency situations such as floods. It is, therefore, deemed advisable that the inventory 18 be kept current. Updating the inventory could also facilitate the monitoring of frequency of inspections and transfers of ownership. 17. RECOMMENDATIONS a. A comprehensive National Dam Safety Program such as outlined in this report should be implemented. State responsibility, under the police powers of the State, to protect the health, safety and welfare of its citizens should be recognized and all States and Terri¬ tories should be encouraged to prosecute dam safety programs encompassing all dams not under Federal authority. b. Implementation of a National Dam Safety Program should be followed immediately by the inspection over a reasonable and practicable time period of all existing dams which have a hazard potential of high or significant, as defined in the Inspection Guidelines, Appendix D. c. Those Federal agencies possessing technical expertise and capabilities in the field of dam design and construction should be authorized to furnish technical assistance and guidance to the Stares, upon request, concerning State programs and the elimination or mitigation of any hazardous conditions which may be found by the States. d. Federal agencies owning and operating dams, owning the land on which dams are located, and the agencies having existing regulatory jurisdiction over dams should prosecute the recommended dam safety program for the dams under their jurisdiction. e. The Chief of Engineers, U.S. Army should be provided authority and funds to maintain current the National Dam Inventory. 19 APPENDIX A RESPONSES TO QUESTIONNAIRE ON SUPERVISION OF DAMS BY STATE AUTHORITIES Contents 1. Questionnaire 2. Responses to Questionnaire Page A-3 A-7 A-1 A survey of each State's and Territory's capabilities, practices and regulations regarding the design, construction, operation and main¬ tenance of dams was conducted by furnishing the Governor of each State and Territory the attached questionnaire on Supervision of Dams by State Authorities. Fifty-three of the 55 States and Territories responded to the questionnaire. The responses from each State and Territory to each of the questions contained in the questionnaire are tabulated on pages A-7 through A-165.

Please state any limitations or exceptions as to size, type, capacity, off-stream location, or class of ownership of dams (or reservoirs) subject to regulations. Alabama Alaska Arizona Arkansas California Colorado Connecticut Delaware Dam must be equal to or greater than 25 feet high or store greater than 50 acre-feet. Barrier less than 6 feet high or storage equal to or less than 15 acre- feet is non-jurisidctional. Permits required for dams which impound 20 acre-feet or more. No permit required for dams constructed by Corps of Engineers, dams which impound only diffused surface waters on land wholly owned by a "person", dams the height of which is at or below the ordinary high water mark on the stream, dams constructed off- stream and dams constructed prior to January 1, 1957. As defined in the code, a "dam" is 25 feet or more in height, storing 50 acre-feet or more. Exceptions include obstructions in canals, levees, highway and railroad fills, circular steel or concrete tanks, certain off- stream barriers for agriculture use, and certain spreading ponds. Any dam less than 10 feet in height -- less than 20 acre highwater surface area or less than 1,000 acre-feet capacity may be excepted -- provided it is less in all three categories. None Shall not apply to: (a) The landlord's right to place a dam across a gully on his property or across a stream that originates on his property where provision is made for continued established average minimum flow occurring for seven (7) consecutive days within the lowest flow year of record; or (b) the right to build and maintain a dam or construct a pond and divert water from any stream having a minimum flow of not more than one-half million gallons of water per day, and utilize up to three hundred sixty (360) acre inches of impounded water per year so long as such action does not affect the established average minimum flow in the stream below the dam at any A-43 10 (Continued) Delaware (Continued) time; or (c) ponds not larger than 60,000 square feet constructed for purposes of conservation, recreation, propagation, and protection of fish and wildlife, watering of stock, or fire protection. Florida DNR DPC Georgia Hawaii Idaho Illinois Indiana Iowa None There are no exceptions as to size, capacity, off- stream location or class of ownership. Chapter 17-9 F.A.C. applies only to the phosphate industry. However, the design criteria in Section 17-9.03 of Chapter 17-9 F.A.C. is used as a guide in insuring that significant impoundments used for treating and/or storing other waste- waters will not violate Chapter 17-3 F.A.C. - Pollution of Waters. Fills less than 10 feet in height (toe to maximum storage level) and which cannot impound 50 acre-feet of water are not classified as dams and are not subject to regulations. Highway fills and canal checks also exempt. None Prior approval of the Natural Resources Commission before construction unless all of following apply: (a) drain¬ age area above dam site less than one square mile, (b) height of dam above natural stream bed or lowest point in the valley less than 20 feet, (c) volume of impounded water to emergency spillway level less than 100 acre-feet, and (d) rights of other property owners not affected. Approval is required for any dam: (1) built for flood control purposes; (2) across any stream or water course which drains more than 5,000 acres; (3) that provides far more than 18 acre-feet permanent storage or more than 25 acre-feet combined permanent and temporary storage and (4) that is in an urban area and is 6 feet or more in height. A-44 10 (Continued) Kansas K.S.A. 82a-301 to 305 does not prohibit the placing in a purely private stream any dam not more than ten feet high and not impounding more than fifteen (15) acre- feet of water.

Louisiana None Maine Maryland Small dams having less than 1 square mile drainage area, less than 15 feet height and less than 12 acres surface area are exempt from permit provided plans and specifi¬ cations approved by Soil Conservation District and meet minimum standards of safety established by State. Massachusetts Not applicable to small dams, constructed for irrigation or for other purposes, the breaking of which would involve no risk to life or property, nor to standpipes or tanks, nor to a dam where the area drainage into the pond formed thereby does not exceed one square mile, unless the dam is more than ten feet in height above the natural bed of the stream at any point, or unless the quantity of water which the dam impounds exceeds one million gallons. Michigan Act 184 applies only to dams that impound over five (5) surface acres or over 5-foot of head. Minnesota Any dams constructed completely outside the beds of public water are exempt from these regulations. Mississippi Must be on stream flowing more than 1/2 MGD and dam must impound more than 300 acre-feet. Missouri Montana There are no limitations. A-45 10 (Continued) Nebraska Dam on an ordinarily dry watercourse for storing water for livestock purposes or for erosion control, with an impounding capacity of not to exceed fifteen acre-feet shall be exempt. Nevada Statutes apply to all dams in excess of 10 feet in height or having a storage capacity in excess of 10 acre-feet. The regulations do not apply to work constructed by the U.S. Bureau of Reclamation or the U.S. Army Corps of Engineers, but plans and specifications are required to be submitted by these two Federal agencies New Hampshire All structures require Board approval. New Jersey Exempts dams on any river or stream which will raise the waters less than five feet or the drainage area above the dam is less than one-half square mile in extent. If off stream no permit required. New Mexico Dams not subject to inspection are those constructed by the United States while under the supervision of the officers of the United States. Dams less than ten feet in height or impoundments containing less than ten acre- feet do not require a permit. Also, dams constructed solely for silt retention and which do not impound or divert water for beneficial use do not require a permit. New York Drainage area less than one square mile; or structure less than ten feet high; or ompoundment less than one million gallons. If any of these parameters are ex¬ ceeded, a permit is required. North Carolina a. Any dam constructed by the United States Army Corps of Engineers, the Tennessee Valley Authority, or any other department or agency of the United States govern¬ ment, when such department or agency designed or approved plans and supervised construction. b. Any dam or flood retarding structure constructed with financial assistance from the United States Soil Conservation Service, when said agency designed or approved plans and supervised construction. c.

C. Dams placed by the Chief in Class V under rule NRd-13-01. Dams may be placed in Class V when failure of the dam would result in property loss restricted almost entirely to the dam, and no loss of human life or hazard to health is envisioned. Only dams which are 20 feet or less in height, and have a storage volume of 50 acre-feet or less, and leave total drainage area of 100 acres or less, shall be placed in Class V. No dam shall be placed in Class V unless the applicant has submitted the preliminary report required by Rule NRd-5-03. Dams under 10 feet high and dams placed in Class V are exempt from the periodic inspection requirements under Section 1521.062. Conservancy district dams and soil and water conservation district assisted dams exempt from construction permit requirements are not exempted from periodic inspection requirements. The Board's responsibility over dams shall be limited to any artificial barrier, together with appurtenant works, which does or may impound or divert water and which either: (a) Is or will be 25 feet or more in height from the natural bed of the stream or water¬ course at the downstream toe of barrier or from the lowest elevation of the outside limit of the barrier, if it is not across a stream channel or watercourse, to the maximum possible water storage elevation; or (b) Has or will have an impounding capacity of 59 acre feet or more. A-48 10 (Continued) Oklahome (Continued) Any such barrier which is or will be not in excess of six (6) feet in height, regardless of storage capacity, or which has or will have a storage capacity not in excess of 15 acre-feet, regardless of height shall not be considered a dam. No obstruc¬ tion in a canal used to raise or tower water therein or divert water therefrom and no fill or structure primarily for highway or railroad traffic shall be considered a dam. Oregon All except: (1) any dam less than 10 feet high or impounding less than 3,000,000 gallons of water; (2) splash dams used for driving logs; (3) farm dikes constructed by individuals on own property and (4) ditches carrying less than 5.0 c.f.s. Pennsylvania A permit from the Department of Environmental Resources is required for the construction of a dam if the drain¬ age area (watershed) above the site of a proposed dam is one-half square mile (320 acres) or more, or if the dam would endanger life or property. However, no permit is required for a dam not exceeding 3 feet in height in a stream not exceeding 50 feet in width, where such dam is constructed for the sole purpose of creating a pool for fish and fishing purposes. Rhode Island Officially all dams are subject to regulation. No official definition of dam; however, we do operate under the unofficial concept that a dam is a structure capable of permanently impounding three (3) or more feet of water. South Carolina None - Bounds of Owners Land. South Dakota Federal Agency Construction (while still under supervision of that agency). Tennessee Limited to non-Federal dams 20 feet or more in height and/or 30 acre-feet in reservoir volume.

Under regulations of your State, please give definition of "Height of Dam" and "Reservoir Capacity." Alabama Alaska Arizona Arkansas California Colorado Connecticut Height - Maximum vertical distance from ground intercept of dam to spillway crest. Reservoir Capacity - storage volume to spillway crest. Height - the vertical distance from the lowest point of foundation surface to the top of dam. Reservoir Capacity - the acre-feet of normal storage below the normal retention level, including dead storage and excluding flood control storage. Height of Dam - is measured "from the natural bed of the stream or watercourse at the downstream toe of the barrier, or from the lowest elevation of the outside limit of the barrier, to the maximum possible water storage elevation." There is not statutory definition of Reservoir Capacity; in practice, it is the capacity in acre-feet at the maximum water storage elevation, including dead storage. Height of Dam - taken at center line at lowest point in valley to crest of dam. Capacity of Reservoir - from outlet invert to emergency spillway crest. Height of Dam - Maximum height of structure above natural ground at spillway level. Capacity of Reservoir Area times average depth. Delaware Not defined. Florida DNR DPC Georgia Hawaii None Not defined by Chapter 17-9 F.A.C. Idaho Height of Dam - Lowest point along downstream toe to maximum water storage. Reservoir Capacity - Volume of water stored below maximum storage elevation. A-54 12. Continued. 12 (Continued) Illinois Indiana Iowa Kansas Kentucky Louisiana Maine Maryland None Height of Dam is the number of feet vertical to top of dam from natural stream bed or lowest point on the valley floor. Reservoir Capacity is the volume of water impounded by the dam to the emergency spillway level. There is no regulation that define these terms. Height of Dam, however, is taken as the vertical distance between the top of the dam and the lowest point of the downstream toe of the embankment. Reservoir Capacity is broken into permanent and temporary storage. Permanent storage is the volume of water which is stored upstream from a dam or in an impoundment up to the level of the principal outlet works of the structure. Temporary storage is a volume of water measured in acre feet which may be stored upstream of a dam or impoundment above the level of the principal outlet works. Height of Dam - Vertical distance from stream bed elevation to elevation of lowest point in the top of the dam along the axis of the dam. Reservoir Capacity - Permanent -- storage in acre-feet at the elevation of the lowest ungated outlet; Detention -- storage in acre-feet between top elevation of permanent storage and crest elevation of emergency spillwayl Surcharge -- storage in acre-feet between crest elevation of emergency spillway and reservoir stage when emergency spillway is in operation. Height of Dam - Difference in elevation in feet between the emergency spillway crest and the lowest point in the original cross-section on the center line of the dam. Reservoir Capacity - Original capacity of the reservoir in acre-feet at the elevation of the crest of the emergency spillway. Not defined by law. N/A Height of Dam - Maximum vertical distance from stream bed to top of dam or spiliway wall. Reservoir Capacity - Volume from low point up to crest of overflow spillway. A- 55 12 (Continued) Massachusetts Michigan Minnesota Mississippi Missouri Montana Nebraska Nevada New Hampshire New Jersey New Mexico Height of Dam - More than 10 feet above the natural stream bed at any point. Reservoir Capacity - exceeds one million gallons. Act 184, PA 1963, as amended refers to "head of dam" which is defined in the statute as the difference in nearest 1/20 foot-between pond headwaters and down¬ stream tail water. No regulation N/A N/A Height of Dam - Twenty-five (25) feet or more in height from the natural bed of the strea or water¬ course measured at the downstream toe of the dam or dike or from the lowest elevation of the outside limit of the dam or dike if it is not across a stream or watercourse, to the maximum storage elevation. Reservoir Capacity - Has or will have an impounding capacity at the maximum water storage elevation of 50 acre-feet or more. Height of Dam - from top to lowest point of structure including piling. Reservoir Capacity - Total from stream bed to top of surcharge pool. Height of Dam - difference in elevation between stream bed at downstream toe of the dam and the crest of the dam. Reservoir Capacity - volume of water impounded behind the dam at the maximum operating level. No limit on height or reservoir capacity exempted.

A-105 25. How is enforcement of supervision achieved? Please explain., Alabama Alaska Arizona Arkansas California Colorado Connecticut Delaware Florida DNR DPC Georgia Hawaii Idaho Illinois By verbal or written order, or by civil court action if required. Any "person" who violates any provision of Act 81 of 1957 is subject to a penalty of not more than $500 a day for each day of such violation. Action may be brought by petition in Superior Court, alleging the violation or threatened violation and praying for relief by mandamus or injunction (article 5, Division 3 of the Water Code). The services of the Attorney General's office are generally used. A violator is guilty of a misdemeanor and is punishable by fine or imprisonment (Chapter 8, Division 3 of Water Code). Denial of storage -- very effective -- $200 per day fine for refusal to comply. Injunctions asked for at trial for fine. By statute, the owner of an unsafe dam may be ordered to repair or remove the structure. N/A Maintenance unadequacies found by the Department can be handled by "Letters of Warnings," "Letters of Violation," or "Notice and Orders." Normal inspections indicate whether or not problems have been allowed to develop. Owner is then required to correct problems. In some cases, the department requires periodic reports of conditions. A-106 25 (Continued) Indiana Iowa Kansas Kentucky Louisiana Maine Maryland Massachusetts (Chapter 84 Acts of 1961 Section 3) "The -- Commission shall, -, have jurisdiction and supervision over the - maintenance and repair of dams, levees, dikes, floodwalls and appurtenant works - and shall exercise care to see that such structures and appurtenances are maintained in a good and sufficient state of repair and/or operating condition to fully perform their intended purposes. The - Commission is authorized ---- to make, adopt and disseminate such rules, regulations and standards for maintenance and/or operation as may be necessary - Under the authority of 455A.33, the Council has the authority to maintain an action in equity to enjoin any person from constructing a dam, other than a dam constructed and operated under the provisions of Chapter 469, for which a permit has not been granted, and, further, has the power to remove or eliminate any dam in any floodway which adversely affects the efficiency of or unduly restricts the capacity of the floodway. In the case of milldams, Chapter 469 authorizes fines for noncompliance with its provisions and also provides for abatement of dams proven to be a nuisance. A condition of the permit issued by the Chief Engineer is as follows: The Chief Engineer reserves the right to require such changes in the maps, plans, profiles, and specifications as may be considered necessary, and further reserves the right to suspend or revoke this permit at any time, should such action be deemed necessary in the interest of public safety, or to prevent serious damage to property. Penalty of up to $1,000 per day for each day of a violation of KRS 151. N/A Structures are inspected by our staff when in the vicinity of the projects. Special inspections are made as the situation warrants. N/A A-107 25 (Continued) Michigan By litigation. Minnesota Through courts as a last result.

Nebraska Nevada If a hazardous situation develops, the State Engineer may issue a formal order regarding operation and maintenance. If there is insufficient time for the issuance of an order, he may lower the water level of the reservoir, completely drain the reservoir or take such other steps as may be necessary to safeguard life or property. New Hampshire Court action if required. New Jersey By direct contact with the owners and application of NJSA58:4-5. New Mexico New York N/A North Carolina Requirement is to maintain minimum flows - monitored by stream gaging by Water Quality Division. North Dakota N/A Ohio Orders are issued by the Chief, Division of Water. Where the construction permit has been issued and the work is not being-performed in accordance with approved A-108 25 (Continued) Ohio (Continued) plans, the Chief may order immediate compliance and suspension of all other work until compliance is effected. If the owner fails to comply, the permit may be revoked and the bond forfeited. The Chief may prohibit the retention of water behind any dam built in violation of Section 1521.06 and the Attorney General may bring an action for an injuction against any person to enforce an order. Under inspection of existing dams, the Chief may order the owner to perform such repairs, maintenance, or other remedial measures as may be necessary to safeguard life, health and property. There is a statutory provision for the State to remove or correct any unsafe structures and have the cost placed on the owner's tax duplicate by the County Auditor. Oklahoma Every person shall be guilty of a misdemeanor who violates any of the provisions of the law or of any order, rule, or regulation of the Board issued pursuant thereto, where acopy of the order, rule, or regulation has been served upon said persons by certified mail and said person fails to comply there¬ with within the time herein provided, or within ten (10) days of such service if not otherwise provided, in the event of a continuing violation, each day that the violation continues constitutes a separate and distinct offense.

Alabama N/A Alaska Arizona Dams built prior to present requirements are jurisdictional and require a permit but no fee is required. Arkansas Dams constructed prior to January 1, 1957 do not require a permit and; therefore, are not inspected. California The department shall require owners (of such dams) to perform at their expense such work or tests as necessary - to safeguard life and property. (Section 6381, of the Water Code). Colorado We inspect for safety and set storage depths. When the structure deteriorates, we order repairs and maintenance together with "as built" and new plans for the repair. Connecticut Periodic inspections. Delaware State policy not formulated at present. F lorida DNR DPC None at this time. All phosphate industry dams must comply with Chapter 17-9 F.A.C. Any inadequate dams are subject to any upgradings as needed to insure compliance with Chapter 17-3 F.A.C. Georgia Hawaii Idaho Visual inspections are made and if definite hazards exist, the department requires that they be corrected. The department does not really try to have all existing facilities conform completely to present criteria.

Kentucky The pre-permit structure can be inspected under authority of KRS 151.290. Louisiana None Maine N/A Maryland Section 17 of the law brings all dams under review and action by the State if found unsafe. Massachusetts Prior to transfer of jurisdiction to the Commissioner of the Massachusetts Department of Public Works, the County Commissioners were responsible for the review and approval of proposed dams, as well as the inspection of existing dams. At present the Commissioner does not have any specific policy with respect to dams previously constructed. Each dam requires inspection at least once every two years according to the statute. The current condition of each dam is evaluated, based upon visual inspection, and appropriate directives are indicated to the owner or caretaker. Michigan These dams fall under authority of Section 2c of Act 184. Public Acts of 1963, as amended. Minnesota Where the structure is of concern, the Department will take appropriate action to insure that unsafe features are corrected.

General Remarks Alabama Alaska Arizona Arkansas California Colorado Connecticut Delaware Florida The Arizona Water Commission assumed responsibility for supervision of the safety or jurisdictional dams in April 1971. Previously this function was administered by the State Highway Department since 1929. The Highway Department was hampered in their supervision of this function because of limited operating funds and personnel. Their function was of necessity, combined with other required Highway responsibilities; consequently, they were unable to devote full time to the supervision of dams program. The Arizona Water Commission has a permanent staff of registered engineers who have considerable experience in the design, construction and operation of dams. Their function is solely devoted to the supervision of dam safety program under the statutory regulations. (1) We do not issue permits. (2) The owner must have approval of plans and specifications prior to con¬ struction. Failure to comply may result in no storage or partial storage only, at most. (3) We find that restriction of storage is sufficient to bring about prompt compliance with repair and maintenance orders. The Water Resources Act of 1972 was amended by the 1973 Legislature giving the Department of Natural Resources (DNR) or Governing Board (s) of the five major water management districts, covering the land and water area of the State of Florida, authority to delineate areas within the district (s) wherein permits may be required for construction, alteration and operation of dams. In those cases where permits are A-160 40 (Continued) Florida Georgia Hawaii Idaho Illinois Indiana Iowa (Continued) required the Department or District (s) are required to make, at their expense, periodic inspections annually, or more frequently as deemed necessary,, At the present time the Department or water management districts do not have a program of supervision of dams. The Department of Pollution Control (DPC) has a program of inspections for phosphate sludge area levees and dam under the regulatory powers authorized for the Department of Pollution Control under the Department of Florida Air and Water Pollution Control Act, 403.061 (25), and rules of the Department of Pollution Control, Chapter 17-4, Permits, and Chapter 17-9, Minimum Requirements for Earthen, Dams Phosphate Mining and Processing Operations. Georgia has no regulatory agency or law governing the construction or maintenance of impoundments. The State Geological Survey are sometimes asked for geologic data to be incorporated for design purposes but have no further input. In Hawaii, construction of dams as well as other types of structures are regulated by local ordinances which are administered by County agencies. As to the specific function of dam supervision, there is no State office or agency assigned this responsibility. The counties do not have any programs, regulations, legislation or policy for the supervision of dams. Chapter 318, Acts of 1945 and Chapter 84, Acts of 1961 refer to the Indiana Flood Control and Water Resources Commission. In 1965 this commission, the Conservation Department and two other small agencies were combined into a new Department of Natural Resources and all duties, responsibilities, powers and authority were vested into the new Natural Resources Commission. In considering an application for a permit to construct a dam, the Resources Council evaluates the submitted plans and associated information to determine whether A-161 40 (Continued) Iowa (Continued) Kansas Kentucky Louisiana Maine Maryland Massachusetts Michigan Minnesota the design is in accordance with sound engineering practices. If there is any doubt as to the adequacy of the design, additional information may be requested or the applicant may be required to install monitoring equipment, keep construction records etc. In the case of post-statutory unauthorized dams, the owner can be required to supply the necessary engineering information needed to determine whether or not such a dam is a nuisance and should be repaired or abated. A nuisance created by a pre-statuatory dam can be abated upon proof by the Resources Council that a nuisance is being created. Budget limitations preclude the carrying out of a sound inspection program of even the Council approved structures, let alone the many pre-statutory structures in Iowa. Our present lack of control is of concern to us. Twice previously the Legislature has been asked to consider a program of dam safety legislation. Such legislation passed both houses in 1973, but failed for lack of funding. The burden of maintaining a dam in a safe condition is placed upon the owner. Inspections are made by State personnel; however, these have been made at irregular intervals. Permits issued by the State normally include a set of conditions which are agreed to by the applicant prior to the issuance of the permit. In issuing a permit in this manner, the permit is cailor made to the specific problems of any one dam. A-162 40 (Continued) Mississippi Missouri Montana Nebraska Nevada New Hampshire New Jersey New Mexico North Carolina North Dakota Ohio Oklahoma Oregon The State has initiated an inspection program for its own dams. One engineer has been designated as Dam Safety Engineer whose primary responsibility is to inspect State dams. New safety equipment has been purchased to make the inspections safer. The State is starting to get some of the repairs made that have been noted during the inspections of its own dams. The State inventory of dams has recently been updated to the current known data. The inventory has been put on computer with all known data. Rules and regulations relating to dam construction and dam safety are granted to the State Engineer under NRS 533.120(1) "The state engineer is empowered to make such reasonable rules and regulations as may be necessary for the proper and order execution of the powers conferred by law." In 1970 we reviewed our Dam Safety Law in comparison with a dam safety model law prepared by the U. S. Committee on Large Dams and also consulted with several members of the USCOLD Committee which drew up the model law. A- 163 40 (Continued) Pennsylvania Rhode Island South Carolina South Dakota Tennessee Plans are underway to introduce legislation patterned after USCOLD Model Law. Recent history of silt dam failure and other semi-liquid impoundment problems have made it necessary to include them within jurisdiction. Of the approximately 2,700 dams within our jurisdiction, approximately 500 are considered as major structures, i.e., their failure could imperil life or property. At the present, South Carolina has, with few exceptions, only common law regulation of dams and reservoirs. These statuatory exceptions pertain, for the most part, to obstruction of the free migration of fish and the resulting requirement for sluices. Other than nuisance remedies under common law, there are no statuatory provisions requiring safety in the design, construction, operation and maintenance of dams. Indirectly, however, several State agencies have some non-safety oriented control over dams and reservoirs, either through permit procedures in Corps of Engineers projects or through the quality of water withheld or discharged. The South Carolina Water Resources Commission is presently drafting comprehensive dam and reservoir legislation. The Commission's draft is calculated to cover all phases of safety oriented regulation. The South Carolina Water Resources Commission will soon complete and Inventory of Lakes for the State which are ten acres in surface area or larger. The Tennessee law and inspection program is completely new. No previous work on dam supervision and/or safety inspection has been carried out. An inventory of all existing non-Federal dams is being conducted. Safety inspections will be initiated after the inventory data is reviewed and proper planning can be carried out. Inspection requirements of the Corps of Engineers are needed prior to full development of the State plan.

Thus virtually all construction except private buildings is planned, financed, and operated by the Trust Territory using funds appropriated by the U. S. Congress. This includes all dams and reservoirs. The design of all dams built so far (since World War II) have been prepared by architectural/engineering consulting firms, and reviewed by Director of Public Works.

General Remarks USDA Forest Service We have several dams (over one thousand) on National Forest lands which have structural deficiencies. Most of these dams were built by other, i.e. miners, cattlemen, etc., and have been abandoned. Some are sizeable structures, and though they are usually in remote areas, they do pose a threat to life and property. We are not adequately financed to do a through job of inspection including the necessary monitoring to determine more precisely, the structural condition. We have grossly inadequate financing for any needed repair work. Soil Conservation Service SCS is not a regulatory agency, therefore many of the above questions are not applicable. Corps of Engineers Civil Works Regulatory Functions USDI Bureau of Indian Affairs Bureau of Land Management No BLM dams have gated outlet works and all dams reported here are generally small and barely meet the criteria for inclusion. Our dam construction program is currently at a standstill and it is unlikely that this status will change in the foreseeable future.

APPENDIX C ^ United States Committee On Large Dams of the International Commission On Large Dams MODEL LAW FOR STATE SUPERVISION OF SAFETY OF DAMS AND RESERVOIRS c-i This model law was prepared by the Committee on Model Legislation for Safety of Dams Alfred R. Golze', Chairman Nicholas L. Earbarossa L. Rees Erooks Wallace L. Chadwick Charles P. Corns Clifford J. Cortright Arthur P. Geuss Thomas G. Harton Clifford H. McConnell T. W. Mermel Karl V. Taylor M.

The objective of the Model Law is safety; protection of areas below a dam from the consequences of a failure of a dam and/or untimely release of its reservoir contents. Design and construction of a dam requires the highest degree of professional engineering performance. The foundation of the dam must be stable under all conditions and capable of carrying the weight of the structure. The dam must impound its reservoir water without undue strain and be safe under the application of external forces such as those resulting from earthquakes. The reservoir area must be water- retentive and free of the possibilities of dangerous slides. Dams and associated facilities must be maintained in excellent condition throughout their life. Operation and surveillance through the years must be conducted in such a manner that any change in the structure of the dam, including its foundation, can be detected promptly and corrections made. If abandoned at any time the dam must be removed or breached to eliminate any hazard to downstream areas. This Model Law provides a guide for states who wish to provide regulations to supervise these elements essential to safe dams and reservoirs. In developing this Model Law advantage was taken of the forty years of experience with the California statutes enacted in C-3 1929 following the failure of the St. Francis Dam with a heavy loss of life and major property damage. The original draft was prepared by a distinguished nationwide committee of professional engineers, experts in the design, construction and management of safe dams and reservoirs. It was submitted in draft form to the Governors of all fifty States for comment. Their comments and those of their staffs are reflected in this Model Law. This Model Law has not been prepared with the expecta¬ tion that it would be adopted without change by any state. Changes to meet constitutional and legal requirements, the organizational structure, and the financial system of the several states is to be expected. Supervision of dams in Federal ownership have been omitted from jurisdiction as the consent of Congress would be necessary to such supervision. In this connection see Arizona v. California, 2$3 u.s. 423. Some states may prefer to put some of the requirements into administrative or technical rules or regulations rather than into the statute itself to provide more flexibility. Experience has shown that incorporation in the basic law removes the require¬ ments from possible frequent changes by a succession of adminis¬ trators. The definition of a dam subject to jurisdiction (Sect. 1002) is expected to vary, state by state, to meet each state’s individual need. The fee schedule requirement (Chapter 6) likewise is optional by states. It is not intended to be of such magnitude as to make the supervision program self-supporting.

It is the intent of the Legislature by this Act to provide for the regulation and supervision of all dams and reservoirs exclusively by the State to the extent required for the protection of public safety. 1026. No city or county has authority, by ordinance enacted by the legislative body thereof or adopted by the people under the initiative power, or otherwise, to regulate, supervise, or provide for the regulation or supervision of any dams or reservoirs in this State, or the construction, maintenance, operation, or removal or abandonment thereof, nor to limit the size of dam or reservoir or the amount of water which may be stored therein, where such authority would conflict with the C-9 powers and authority vested in the Agency by this Act. This Act shall not prevent a city or county from adopting ordinances regulating, supervising, or providing for the regulation or supervision of dams and reservoirs that (a) are not within the StateTs jurisdiction, (b) are not subject to regulation by another public agency or body, or apply only to appurtenances such as roads and fences not germane to the safety of the structure. 1027. All plans and specifications for initial con¬ struction, enlargement, alteration, repair or removal of dams and supervision of construction shall be in charge of a civil engineer, licensed by this State, experienced in dam design and construction, assisted by qualified engineering geologists and other specialists when necessary. 1028. No action shall be brought against the State or the Agency or its agents or employees for the recovery of damages caused by the partial or total failure of any dam or reservoir or through the operation of any dam or reservoir upon the ground that such defendant is liable by virtue of any of the following: (a) The approval of the dam or reservoir, or approval of flood handling plans during construction. (b) The issuance or enforcement of orders relative to maintenance or operation of the dam or reservoir. (c) Control and regulation of the dam or reservoir. (d) Measures taken to protect against failure during an emergency. 1029. Nothing in this Act shall be construed to relieve an owner or operator of a dam or reservoir of the legal duties, C-10 obligations, or liabilities incident to the ownership or operation of the dam or reservoir. 1030. The findings and orders of the Agency and the certificate of approval of any dam or reservoir issued by the State are final and conclusive and binding upon all owners, and State agencies, regulatory or otherwise, as to the safety of design, construction, maintenance, and operation of any dam or reservoir. 1031. Nothing in this Act shall be construed to deprive any owner of such recourse to the courts as he may be entitled to under the laws of this State. 1032. All records of official actions of the Agency and its correspondence pertaining to the supervision of dams and reservoirs are public documents. 1033. All owners shall notify the Agency of any change in ownership of any dam or reservoir subject to this Act at the time the transfer of ownership occurs. Chapter 3. Administrative Provisions 1050. The Agency shall be administered and directed by a civil engineer, licensed by this State, experienced in the design and construction of dams and reservoirs, and it shall employ such clerical, engineering, and other assistants as are necessary for carrying on the work of dam and reservoir super¬ vision in accordance with this Act. 1051. When the safety considerations pertaining to a certificate of approval, dam, reservoir, or plans and specifica¬ tions require it, or when requested in writing to do so by the C-ll owner, the Agency may appoint a consulting board of two or more consultants not previously associated with the structure, to report to the Agency on its proposed action with respect to these considerations. 3052. The cost and expense of a consulting board if appointed on the request of an owner shall be paid by the owner. Chapter 4. Powers of the Agency Article 1.

Chapter 7. Inspection and Approval Article 1. New or Enlarged Dams and Reservoirs 1150. Immediately upon completion of a new dam and reservoir or enlargement of a dam and reservoir the owner shall give a notice of completion to the Agency, and as soon thereafter as possible shall file with the Agency a certificate signed by the responsible engineer supervising construction for the owner, certifying that, the project was constructed in conformance with approved plans and specifications, accompanied by supplementary drawings or descriptive matter showing or describing the dam or reservoir as actually constructed, which shall include but not be limited to the following: (a) A record of all geological boreholes and grout holes and grouting. (b) A record of permanent location points, benchmarks and instruments embedded in the structure. (c) • A record of .tests of concrete or other material used in the construction of the dam and reservoir. (d) A record of seepage flows and embedded instrument readings. C-22 1151. In connection with the enlargement of a dam and reservoir, the supplementary drawings and descriptive matter need apply only to the new work. 1152. A certificate of approval shall be issued by the Agency upon a finding by the Agency that the dam and reservoir are safe to impound water within the limitations prescribed in the certificate. No water shall be impounded by the structure prior to issuance of the certificate. Article 2. Certificates of Approval 1153. Each certificate of approval issued by the Agency under this Act may contain such terms and conditions as the Agency may prescribe’. 1154. The Agency may revoke or suspend any certificate of approval whenever it determines that the dam or reservoir constitutes a danger to life and property. Whenever it deems such action necessary to safeguard life and property, the Agency may also amend the terms and conditions of any such certificate by issuing a new certificate containing the revised terms and conditions. 1155. Before any certificate of approval is revoked by the Agency, the Agency shall hold a hearing. Written notice of the time and place of the hearing shall be mailed, at least twenty days prior to the date set for the hearing, to the holder of the certificate. Any interested persons may appear at the hearing an'd present their views and objections to the proposed action. Any petition to a court of appropriate jurisdiction to C-23 inquire into the validity of action of the Agency revoking a certificate of approval shall be commenced within thirty days after service of notice of the revocation on the holder of the certificate. Article 3• Repaired or Altered Dams and Reservoirs 1156. Immediately upon completion of the repair or alteration of any dam or reservoir, the owner shall give notice of completion to the Agency and as soon thereafter as possible shall file with the Agency a certificate signed by the responsible engineer supervising the work for the owner that the repairs or alterations were completed in accordance with the approved plans and specifications, accompanied by supplementary drawings or descriptive matter showing or describing the dam or reservoir as actually repaired or altered together with such maps, data, records, and information pertaining to the dam or reservoir as repaired or altered as the Agency requires. 1157. A certificate o£ approval shall be issued by the Agency upon a finding by the Agency that the dam and reservoir are safe to impound water within the limitations prescribed in the certificate. Pending issuance of a new certificate of approval, the owner of the dam or reservoir shall not, through action or inaction, cause the dam or reservoir to impound water beyond the limitations prescribed in the existing certificate. 115$. The certificate of approval shall supersede any previous certificate of approval issued for the dam or reservoir so repaired or altered. C-2'4 Article 4. Removal of Dams and Reservoirs 1159. Upon completion of the removal of a dam or complete drawdown of a reservoir such evidence as to the manner in which the work was performed and as to the conditions obtain¬ ing after the removal as the Agency requires shall be filed with the Agency. 1160. This evidence shall show that a sufficient portion of the dam has been removed to permit the safe passage of floods down the watercourse across which the dam was located, within flooding criteria required by the Agency, and that adequate provision has been made by the owner to prevent damage downstream from the remaining portion of the dam by subsequent flooding of downstream areas under such criteria. 1161. Before final approval of the removal of a dam or reservoir is issued, the Agency shall inspect the site of the work and determine that all danger to life and property as a result thereof has been eliminated. Article 5. Complaints as to Unsafe Conditions 1162. Upon receipt of a written complaint alleging that the person or property of the complainant is endangered by the construction, enlargement, repairs, alterations, maintenance, or operation of any dam or reservoir the Agency shall cause an inspection to be made unless the data, records, and inspection reports on file with it are found adequate to make a determina¬ tion whether the complaint is valid. H63. If the Agency authorizes an inspection the complainant shall deposit with the Agency a sum estimated by it C-25 to be sufficient to cover costs of the inspection. The Agency- may utilize independent consultants of its selection to make the inspection and a report to the Agency. 1164. If it is found that an unsafe condition exists, the Agency shall notify the owner to take such action as is necessary to render or cause the condition to be rendered safe, including breaching or removal of any dam found beyond repair, and any money deposited to secure an inspection shall be returned. 1165. If, after an inspection is made on account of a complaint, the complaint is found by the Agency to have been without merit, the cost therefor shall be payable into the Special Fund in State Treasury from the money deposited, with any excess returned to the complainant. The complainant will be provided with a copy of the official report of the inspection. Article 6. Inspection During Progress of Work 1166. During the construction, enlargement, repair, alteration, or removal of any dam or reservoir the Agency shall make eioher with its own engineers or by consulting engineers or engineering organizations, periodic inspections at State expense for the purpose of ascertaining compliance ’with the approved plans and specifications. The Agency shall require the owner to perform at his expense such work or tests as necessary, provide adequate supervision during construction by a civil engineer registered or licensed by the laws of this State, and to disclose information sufficient to enaole the Agency to determine that conformity with the approved plans and specifi¬ cations is b^ing secured. C-26 1167. If) after any inspections, investigations, or examinations, or at any time as the work progresses, or at any time prior to issuance of a certificate of approval it is found by the Agency that amendments, modifications, or changes are necessary to ensure "safety, the Agency may order the owner to revise his plans and specifications, provided, however, the owner may, pursuant to Section 1051, request an independent consulting board to review the order of the Agency. 1168. If conditions are revealed which will not permit the construction of a safe dam or reservoir the Agency’s approval shall be revoked. 1169. In the event that conditions imposed may be waived or made less burdensome in its judgment without sacri¬ ficing safety, the Agency may authorize an owner to revise the plans and specifications accordingly. 1170. If at any time during construction, enlarge¬ ment, repair, or alterations of any dam or reservoir the Agency finds that the work is not being done in accordance with the provisions of the original approved plans and specifications or in accordance with the approved revised plans and specifica¬ tions, it shall give a written notice thereof and order compli¬ ance by registered mail or by personal service to the owner. 1171. The notice and order shall state the particulars in which the original approved plans and specifications or the approved revised plans and specifications are not being or have not been complied with and shall order the immediate compliance with the original approved plans and specifications or with the 027 approved revised plans and specifications as the case may be. 1172. The Agency may order that no further work be done until such compliance has been effected and approved by the Agency. 1173 • A failure to comply with the approval and approved plans and specifications shall render the approval sub¬ ject to revocation by the Agency, if compliance is not made in accordance therewith after notice and order from the Agency as provided in this article. If compliance is not forthcoming in a reasonable time, the Agency may order the incomplete structure removed sufficiently to eliminate any safety hazard to life or property. Chapter 8. Maintenance, Operation and Emergency Work Article 1. Maintenance and Operation 1174* Supervision over the maintenance and operation of dams and reservoirs in this State, other than those owned by the Federal Government, insofar as necessary to safeguard life and property from injury by reason of the failure thereof is vested in the Agency. 1175. The Agency shall require owners or their agents to keep available and in good order records of original and any modification construction and to report annually with respect to maintenance, operation and engineering including piezometric data and geologic investigations.

The Agency, from time to time, but not less often than once every five years, either with its own engineers, or by consulting engineers or engineering organizations, shall make inspections of dams and reservoirs at State expense for the purpose of determining their safety but shall require owners to perform at their expense such work as may reasonably be required to disclose information sufficient to enable the Agency to deter¬ mine conditions of dams and reservoirs in regard to their safety and to perform at their expense other work which may reasonably be required, including installation of instruments necessary to secure maintenance and operation which will safeguard life and property. Article 2. Emergency Work 1177. The Agency shall be responsible for determining that an emergency exists and through normal disaster communica¬ tion channels shall warn the public, immediately employing any remedial means necessary to protect life and property, if in its judgment either: (a) The condition of any dam or reservoir is so dangerous to the safety of life or property as not to permit of time for the issuance and enforcement of an order relative to maintenance or operation. (b) Passing or imminent floods or any other condition which threaten the safety of any dam or reservoir. C-29 1178. In applying the remedial means provided for in this article, the Agency may in emergency with its own forces, or by other means at its disposal, do any of the following: (a) Take full charge and control of any dam or reservoir. (b) Lower the water level by releasing water from the reservoir. (c) Completely empty the reservoir. (d) Perform any necessary remedial or protective work at the site. (e) Take such other steps as may be essential to safeguard life and property. 1179. The Agency shall continue in full charge and control of such dam or reservoir, or both, and its appurtenances until they are rendered safe or the emergency occasioning the action has ceased and the owner is able to take back such opera¬ tions. The Agency's take over will not operate to relieve the owner of a dam or reservoir of liability for any negligent acts of the owner or his agents. 1180. The cost and expense of the remedial means provided in this article, including cost of any work done to render a dam or reservoir or its appurtenances safe, shall be collected by presentation of bills to owners in the same manner as other debts to the Stare are recoverable, provided that if such bills are not promptly paid by the owners the cost shall be recovered by the State from the owner by action brought by the Agency in a court of appropriate jurisdiction.

C-31 Chapter 10. Dams and. Reservoirs Existing Prior to the Effective Date of this Law Article 1. Dams and Reservoirs Completed Prior to Effective Date of this Lav/ 1200. Every owner of a dam or reservoir that falls within the definition of a dam or reservoir in this Act that V was completed prior to the effective date of this Law shall immediately file an application with the Agency for the approval of such dam or reservoir. 1201. A separate application for each reservoir and its dams shall be filed with the Agency upon forms to be supplied by it and shall include or be accompanied by such appropriate information concerning the dams or reservoir as the Agency requires. 1202. The Agency shall give notice to file an application to owners of such dams or reservoirs who have failed to do so as required by this article, and a failure to file within thirty days after such notice shall be punishable as provided in this Act. 1203. The notice provided for in this article shall be given by certified mail to the owner at his last address of record in the office of the county assessor of the county in which the dam is located and such mailing shall constitute service. 1204. The Agency shall make inspections of such dams or reservoirs -at State expense. 1203. The Agency shall require owners of such dams or reservoirs to perform at their expense such work or tests as C-32 'iS. may reasonably be required to disclose information sufficient to enable the Agency to determine whether to issue certificates of approval or to issue orders directing further work at the owner’s expense necessary to safeguard life and property. For this purpose, the Agency may require an owner to lower the water level of, or to empty, the reservoir. 1206. If, upon inspection or upon completion to the satisfaction of the Agency of all work that may be ordered, the Agency finds that the dam and reservoir are safe to impound water, a certificate of approval shall be issued. The owner of the dam or reservoir shall not, through action or inaction, cause the dam or reservoir to impound water following receipt by the owner of a written notice from the Agency that a certificate will not be issued because the dam or reservoir will not safely impound water. Before such notice is given by the Agency, the Agency shall hold a hearing. Written notice of the time and place of the hearing shall be mailed, at least twenty days prior to the date set for the hearing, to the owner of the dam or reservoir. Any interested persons may appear at the hearing and present their views and objections to the proposed action. Article 2. Dams and Reservoirs Under Construction Before Effective Date of this Law 1207. Any dam or reservoir that falls within the definition of a dam or reservoir in this Act and which the Agency finds was under construction and based on its findings not 90 percent constructed on the effective date of this Law C-33 shall, except as provided in Section 1208, be subject to the same provisions in this Act as a dam or reservoir commenced after that date. Every owner of such a dam or reservoir shall file an application with the Agency for the Agency's written approval of the plans and specifications of the dam or reservoir. 1208. Construction work on such a dam or reservoir may proceed, provided an application for approval of the plans and specifications therefor is filed, until a certificate of approval is received by the owner from the Agency approving the dam and reservoir or an order is received by the owner from the Agency specifying how the construction must be performed to render the dam or reservoir safe. After receipt of an order specifying how construction of the dam or reservoir must be performed, work thereafter must be in accordance with the order. 1209.. Such dams or reservoirs as are based on Agency findings 90 percent or more constructed on the effective date of this Law shall be subject to the same supervision as dams or reservoirs which were completed prior thereto. Article 3. Fees for Dams or Reservoirs Under Construction Before Effective Date of this Law 1210.

CORPS Of l; ^2SL», - PREFACE The recommended guidelines for the safety inspection of dams were prepared to outline principal factors to be weighed in the determination of existing or potential hazards and to define the scope of activities to be undertaken in the safety inspection of dams. The establishment of rigid criteria or standards is not intended. Safety must be evaluated in the light of peculiarities and local conditions at a particular dam and in recognition of the many factors involved, some of which may not be precisely known. This can only be done by competent, experienced engineering j.udgement, which the guidelines are intended to supplement and not supplant. The guidelines are intended to be flexible, and the proper flexibility must be achieved through the employment of experienced engineering personnel. Conditions found during the investigation which do not meet guideline recommendations should be assessed by the investigator as to their import from the standpoint of the involved degree of risk. Many deviations will not compromise project safety and the investigator is expected to identify them in this manner if that is the case. Others will involve various degrees of risk, the proper evaluation of which will afford a basis for priority of subsequent attention and possible remedial action. The guidelines present procedures for investigating and evaluating existing conditions for the purpose of identifying deficiencies and hazardous conditions. The two phases of investigation outlined in the guidelines are expected to accomplish only this and do not encompass in scope the engineering which will be required to perform the design studies for corrective modification work. It is recognized that some States may have established or will adopt inspection criteria incongruous in some respects with these guidelines. In such instances assessments of project safety should recognize the State's requirements as well as guideline recommendations. The guidelines were developed with the help of several Federal agencies and many State agencies, professional engineering organizations, and private engineers. In reviewing two drafts of the guidelines they have contributed many helpful suggestions. Their contributions are deeply appreciated and have made it possible to evolve a document representing a consensus of the engineering fraternity. As experience is gained with use of the guidelines, suggestions for future revisions will be generated. All such suggestions should be directed to the Chief of Engineers, U.S. Army, DAEN-CWE-D, Washington, D.C. 20314.

Purpose. This document provides recommended guidelines for the inspection and evaluation of dams to determine if they constitute hazards to human life or property. 1.2. Applicability. The procedures and guidelines outlined in this document apply to the inspection and evaluation of all dams as defined in the National Dam Inspection Act, Public Law 92-367. Included in this program are all artificial barriers together with appurtenant works which impound or divert water and which (1) are twenty-five feet or more in height or (2) have an impounding capacity of fifty acre-feet or more. Not included are barriers which are six feet or less in height, regardless of storage capacity, or barriers which have a storage capacity at maximum water storage elevation of fifteen acre-feet or less regardless of height. 1.3. Authority. The Dam Inspection Act, Public Law 92-367 (Appendix III), authorized the Secretary of the Army, through the Corps of Engineers, to i itiate a program of safety inspection of dams throughout the United States. The Chief of Engineers issues these guidelines pursuant to that authority. CHAPTER 2 - GENERAL REQUIREMENTS 2.1. Classification of Dams. Dams should be classified in accordance with size and hazard potential in order to formulate a priority basis for selecting dams to be included in the inspection program and also to provide compatibility between guideline requirements and involved risks. When possible the initial classifications should be based upon information listed in the National Inventory of Dams with respect to size, impoundment capacity and hazard potential. It may be necessary to reclassify dams when additional information becomes available. 2.1.1. Size. The classification for size based on the height of the dam and storage capacity should be in accordance with Table 1. The height of the dam is established with respect to the maximum storage potential measured from the natural bed of the stream or watercourse at the downstream toe of the barrier, or if it is not across a stream or watercourse, the height from the lowest elevation of the outside limit of the barrier, to the maximum water storage elevation. For the purpose of determining project size, the maximum storage elevation may be considered equal to the top of dam elevation. Size classification may be determined by either storage or height, whichever gives the larger size category. TABLE 1 SIZE CLASSIFICATION Category Impoundment Storage (Ac-Ft) Height (Ft) Small < 1000 and-^50 ^ 40 and 25 Intermediate ^ 1000 and< 50,000 40 and ^ 100 Large rh 50,000 ^ 100 2.1.2. Hazard Potential. The classification for potential hazards should be in accordance with Table 2. The hazards pertain to potential loss of human life or property damage in the area downstream of the dam in event of failure or misoperation of the dam or appurtenant facilities. Dams conforming to criteria for the lew hazard potential category generally will be located in rural or agricultural areas where failure may damage farm buildings, limited agricultural land, or township and country roads. Significant hazard potential category structures will be those located in predominantly rural or agricultural areas where failure may damage isolated homes, secondary highways or minor railroads D-8 or cause interruption of use or service of relatively important public utilities. Dams in the high hazard potential category will be those located where failure may cause serious damage to homes, extensive agricultural, industrial and commercial facilities, important public utilities, main highways, or railroads. TABLE 2 HAZARD POTENTIAL CLASSIFICATION Category Loss of Life (Extent of Development) Economic Loss (Extent of Development) Low None expected (No per¬ manent structures for human habitation) Minimal (Undeveloped to occasional structures or agriculture) Significant Few (No urban develop¬ ments and no more than a small number of inhabitable structures) Appreciable (Notable agriculture, industry or structures) High More than few Excessive (Extensive community, industry or agriculture) 2.2. Selection of Dams to be Investigated. The selection of dams to be investigated should be based upon an assessment of existing develop¬ ments in flood hazard areas. Those dams possessing a hazard potential classified high or significant as indicated in Table 2 should be given first and second priorities, respectively, in the inspection program. Inspection priorities within each category may be developed from a consideration of factors such as size classification and age of the dam, the population size in the downstream flood area, and potential develop¬ ments anticipated in flood hazard areas. 2.3. Technical Investigations. A detailed, systematic, technical inspection and evaluation should be made of each dam selected for investigation in which the hydraulic and hydrologic capabilities, structural stability and operational adequacy of project features are analyzed and evaluated to determine if the dam constitutes a danger co human life or property. The investigation should vary in scope and completeness depending upon the availability and suitability of engineering data, the validity of design assumptions and analyses and uhe condition of the dam. The minimum investigation will be designated Phase I, and an in-depth investigation designated Phase II should be D-9 I made where deemed necessary. Phase I investigations should consist of a visual inspection of the dam, abutments and critical appurtenant structures, and a review of readily available engineering data. It is not intended to perform costly explorations or analyses during Phase I Phase II investigations should consist of all additional engineering investigations and analyses found necessary by results of the Phase I investigation. 2.4. Qualifications of Investigators. The technical investigations should be conducted under the direction of licensed professional engineers experienced in the investigation, design, construction and operation of dams, applying the disciplines of hydrologic, hydraulic, soils and structural engineering and engineering geology. All field inspections should be conducted by qualified engineers, engineering geologists and other specialists, including experts on mechanical and electrical operation of gates and controls, knowledgeable in the investigation, design, construction and operation of dams. I D- 10 ( CHAPTER 3 - PHASE I INVESTIGATION 3.1. Purpose. The primary purpose of the Phase I investigation program is to identify expeditiously those dams which may pose hazards to human life or property. 3.2. Scope. The Phase I investigation will develop an assessment of the general condition with respect to safety of the project based upon available data and a visual inspection, determine any need for emergency measures and conclude if additional studies, investigation and analyses are necessary and warranted. A review will be made of pertinent existing and available engineering data relative to the design, construction and operation of the dam and appurtenant structures, including electrical and mechanical operating equipment and measurements from inspection and performance instruments and devices; and a detailed systematic visual inspection will be performed of those features relating to the stability and operational adequacy of the project. Based upon findings of the review of engineering data and the visual inspection, an evaluation will be made of the general condition of the dam, including where possible the assessment of the hydraulic and hydrologic capa¬ bilities and the structural stability. 3.3. Engineering Data. To the extent feasible the engineering data listed iii Appendix I relating to the design, construction and operation of the dam and appurtenant structures, should be collected from existing records and reviewed to aid in evaluating the adequacy of hydraulic and hydrologic capabilities and stability of the dam. Where the necessary engineering data are unavailable, inadequate or invalid, a listing should be made of those specific additional data deemed necessary by the engineer in charge of the investigation and included in the Phase I report. 3.4. Field Inspections. The field inspection of the dam, appurtenant structures, reservoir area, and downstream channel in the vicinity of the dam should be conducted in a systematic manner to minimize the pos¬ sibility of any significant feature being overlooked. A detailed check¬ list should be developed and followed for each dam inspected to document the examination of each significant structural and hydraulic feature including electrical and mechanical equipment for operation of the con¬ trol facilities that affect the safety of the dam. 3.4.1. Particular attention should be given to detecting evidence of leakage, erosion, seepage, slope instability, undue settlement, displace¬ ment, tilting, cracking, deterioration, and improper functioning of drains and relief wells. The adequacy and quality of maintenance and D-11 operating procedures as they pertain to the safety of the dam and operation of the control facilities should also be assessed. 3.4.2. Photographs and drawings should be used freely to record con¬ ditions in order to minimize descriptions. 3.4.3. The field inspection should include appropriate features and items, including but not limited to those listed in Appendix II, which may influence the safety of the dam or indicate potential hazards to human life or property. 3.5. Evaluation of Hydraulic and Hydrologic Features. 3.5.1. Design Data. Original hydraulic and hydrologic design assumptions obtained from the project records should be assessed to determine their acceptability in evaluating the safety of the dam. All constraints on water control such as blocked entrances, restrictions on operation of spillway and outlet gates, inadequate energy dissipators or restrictive channel conditions, significant reduction in reservoir capacity by sediment deposits and other factors should be considered in evaluating the validity of discharge ratings, storage capacity, hydrographs, routings and regula¬ tion plan. The discharge capacity and/or storage capacity should be capable of safely handling the recommended spillway design flood for the size and hazard potential classification of the dam as indicated in Table 3. The hydraulic and hydrologic determinations for design as obtained from project records will be acceptable if conventional tech¬ niques similar to the procedures outlined in paragraph 4.3. were used in obtaining the data. When the project design flood actually used exceeds the recommended spillway design flood, from Table 3, the project design flood will be acceptable in evaluating the safety of the dam. TABLE 3 HYDROLOGIC EVALUATION GUIDELINES RECOMMENDED SPILLWAY DESIGN FLOODS Hazard Size ^Spillway Design Flood (SDF) Low Small Intermediate Large 50 to 100-yr freq 100-yr to 1/2 PMF 1/2 PMF to PMF Significant Small Intermediate Large 100-yr to 1/2 PMF 1/2 PMF to PMF PMF (TABLE 3 Continued on next page) D-12 (TABLE 3 Continued) Hazard High Size ^Spillway Design Flood (SDF) Small 1/2 PMF to PMF Intermediate PMF Large PMF *The recommended design floods in this column represent the magnitude of the spillway design flood (SDF), which is intended to represent the largest flood that need be considered in the evaluation of a given project, regard¬ less of whether a spillway is provided; i.e., a given project should be capable of safely passing the appropriate SDF. Where a range of SDF is indicated, the magnitude that most closely relates to the involved risk should be selected. 100-yr = 100-Year Exceedence Interval. The flood magnitude expected to be exceeded, on the average, of once in 100 years. It may also be expressed as an exceedence frequency with a one-percent chance of being exceeded in any given year. PMF = Probable Maximum Flood. The flood that may be expected from the most severe combination of critical meteorologic and hydrologic conditions that are reasonably possible in the region. The PMF is derived from probable maximum precipitation (PMP), which information is generally available from the National Weather Service, NOAA. Most Federal agencies apply reduction factors to the PMP when appropriate. Reductions may be applied because rainfall isohyetals are unlikely to conform to the exact shape of the drainage basin and/or the storm is not likely to center exactly over the drainage basin. In some cases local topography will cause changes from the generalized PMP values, therefore, it may be advisable to contact Federal construction agencies to obtain the prevailing practice in specific areas. 3.5.2. Experience Data. In some cases where design data are lacking, an evaluation of overtopping potential may be based on watershed char¬ acteristics and rainfall and reservoir records. An estimate of the probable maximum flood may also be developed from a conservative, generalized comparison of the drainage area size and the magnitude of recently adopted probable maximum floods for damsites in comparable hydrologic regions. Where the review of such experience data indicates that the recommended spillway design flood would not cause overtopping additional hydraulic and hydrologic determinations will be unnecessary. D-13 3.6. Evaluation of Structural Stability. The Phase I evaluations of structural adequacy of project features are expected to be based princi¬ pally on existing conditions as revealed by the visual inspection, together with available design and construction information and records of perfor¬ mance. The objectives are to determine the existence of conditions which are hazardous, or which with time might develop into safety hazards, and to formulate recommendations pertaining to the need for any additional studies, investigations, or analyses. The results of this phase of the inspection must rely very substantially upon the experience and judgment of the inspecting engineer. 3.6.1. Design and Construction Data. The principal design assumptions and analyses obtained from the project records should be assessed. Original design and construction records should be used judiciously, recognizing the restricted applicability of such data as material strengths and permeabilities, geological factors and construction descrip¬ tions. Original stability studies and analyses should be acceptable if conventional techniques and procedures similar to those outlined in paragraph 4.4 were employed, provided that review of operational and performance data confirm that the original design assumptions were adequately conservative. The need for such analyses where either none exist or the originals are incomplete or unsatisfactory will be determined by the inspecting engineer based upon other factors such as condition of structures, prior maximum loadings and the hazard degree of the project. Design assumptions and analyses should include all applicable loads including earthquake and indicate the structure's capability to resist overturning, sliding and overstressing with adequate factors of safety. In general seepage and stability analyses comparable to the requirements of paragraph 4.4 should be on record for all dams in the high hazard category and large dams in the significant hazard category. This require¬ ment for other dams will be subject to the opinion of the inspecting engineer. 3.6.2. Operating Records. The performance of structures under prior maximum loading conditions should in some instances provide partial basis for stability evaluation. Satisfactory experience under loading con¬ ditions not expected to be exceeded in the future should generally be indicative of satisfactory stability, provided adverse changes in physical conditions have not occurred. Instrumentation observations of forces, pressures, loads, stresses, strains, displacements, deflections or other related conditions should also be utilized in the safety evaluation. Where such data indicate abnormal behavior, unsafe move¬ ment or deflections, or loadings which adversely affect the stability or functioning of the structure, prompt reporting of such circumstances is required without the delay for preparation of the official inspection report. D-14 3.6.3. Post Construction Changes. Data should be collected on changes which have occurred since project construction that might influence the safety of the dam such as road cuts, quarries, mining and groundwater changes. 3.6.4. Seismic Stability. An assessment should be made of the potential vulnerability of the dam to seismic events and a recommendation developed with regard to the need for additional seismic investigation. In general, projects located in Seismic Zones 0, 1 and 2 may be assumed to present no hazard from earthquake provided static stability conditions are satis¬ factory and conventional safety margins exist. Dams in Zones 3 and 4 should, as a minimum, have on record suitable analyses made by conven¬ tional equivalent static load methods. The seismic zones together with appropriate coefficients for use in such analyses are shown in Figures 1 through 4. Boundary lines are approximate and in the event of doubt about the proper zone, the higher zone should be used. All high hazard category dams in Zone 4 and high hazard dams of the hydraulic fill type in Zone 3 should have a stability assessment based upon knowledge of regional and local geology, engineering seismology, in situ properties of materials and appropriate dynamic analytical and testing procedures. The assessment should include the possibility of physical displacement of the structures due to movements along active faults. Departure from this general guidance should be made whenever in the judgment of the investigating engineer different seismic stability requirements are warranted because of local geological conditions or other reasons. D-15 CHAPTER 4 - PHASE II INVESTIGATION 4.1. Purpose. The Phase II investigation will be supplementary to Phase I and should be conducted when the results of the Phase I investigation indicate the need for additional in-depth studies, investigations or analyses. 4.2. Scope. The Phase II investigation should include all additional studies, investigations and analyses necessary to evaluate the safety of the dam. Included, as required, will be additional visual inspections, measurements, foundation exploration and testing, materials testing, hydraulic and hydrologic analysis and structural stability analyses. 4.3. Hydraulic and Hydrologic Analysis. Hydraulic and hydrologic capabilities should be determined using the following criteria and pro¬ cedures. Depending on the project characteristics, either the spillway design flood peak inflc.r or the spillway design flood hydrograph should be the basis for determining the maximum water surface elevation and maximum outflow. If the operation or failure of upstream water control projects would have significant impact on peak flow or hydrograph analyses, the impact should be assessed. 4.3.1. Maximum Water Surface Based on SDF Peak Inflow. When the total project discharge capability at maximum pool exceeds the peak inflow of the recommended SDF, and operational constraints would not prevent such a release at controlled projects, a reservoir routing is not required. The maximum discharge should be assumed equal to the peak inflow of the spillway design flood. Flood volume is not controlling in this situation and surcharge storage is either absent or is significant only to the extent that it provides the head necessary to develop the release capability required. 4.3.1.1. Peak for 100-Year Flood. When the 100-year flood is applicable under the provisions of Table 3 and data are available, the spillway design flood peak inflow may be determined by use of "A Uniform Technique for Determining Flood Frequencies," Water Resources Council (WRC), Hydrology Committee, Bulletin 15, December 1967. Flow frequency information from regional analysis is generally preferred over single station results when available and appropriate. Rainfall-runoff techniques may be necessary when there are inadequate runoff data available to make a reasonable estimate of flow frequency. 4.3.1.2. Peak for PMF or Fraction Thereof. When either the Probable Maximum Flood peak or a fraction thereof is applicable under the provi¬ sions of Table 3, the unit hydrograph - infiltration loss technique is generally the most expeditious method of computing the spillway design flood peak for most projects. This technique is discussed in the following paragraph. 4.3.2. Maximum Water Surface Based on SDF Hydrograph. Both peak and volume are required in this analysis. Where surcharge storage is signifi¬ cant, or where there is insufficient'discharge capability at maximum pool to pass the peak inflow of the SDF, considering all possible operational constraints, a flood hydrograph is required. When there are upstream hazard areas that would be imperiled by fast rising reservoirs levels, SDF hydrographs should be routed to ascertain available time for warning and escape. Determination of probable maximum precipitation or 100-year precipitation, whichever is applicable, and unit hydrographs or runoff models will be required, followed by the determination of the PMF or 100- year flood. Conservative loss rates (significantly reduced by antecedent rainfall conditions where appropriate)should be estimated for computing the rainfall excess to be utilized with unit hydrographs. Rainfall values are usually arranged with gradually ascending and descending rates with the maximum rate late in the storm. When applicable, conservatively high snowmelt runoff rates and appropriate releases from upstream projects should be assumed. The PMP may be obtained from National Weather Service (NWS) publications such as Hydrometeorological Report (HMR) 33. Special NWS publications for particular areas should be used when avail¬ able. Rainfall for the 100-year frequency flood can be obtained from the NWS publication "Rainfall Frequency Atlas of the United States," Technical Paper No. 40; Atlas 2, "Precipitation Frequency Atlas of Western United States;" or other NWS publications. The maximum water surface elevation and spillway design flood outflow are then determined by routing the inflow hydrograph through the reservoir surcharge storage, assuming a starting water surface at the bottom of surcharge storage, or lower when appropriate. For projects where the bottom of surcharge space is not distinct, or the flood control storage space (exclusive of surcharge) is appreciable, it may be appropriate to select starting water surface elevations below the top of the flood control storage for routings. Conservatively high starting levels should be estimated on the basis of hydrometeorological conditions reasonably characteristic for the region and flood release capability of the project. Necessary adjustment of reservoir storage capacity due to existing or future sediment or other encroachment may be approximated when accurate determination of deposition is not practicable. 4.3.3. Acceptable Procedures. Techniques for performing hydraulic and hydrologic analyses are generally available from publications prepared by Federal agencies involved in water resources development or textbooks written by the academic community. Some of these procedures are rather sophisticated and require expensive computational equipment and large data banks. While results of such procedures are generally more reliable than simplified methods, their use is generally not warranted in studies con¬ nected with this program unless they can be performed quickly and inexpen¬ sively. There may be situations where the more complex techniques have to be employed to obtain reliable results; however, these cases will be exceptions rather than the rule. Whenever the acceptability of procedures is in question, the advice of competent experts should be sought. Such expertise is generally available in the Corps of Engineers, Bureau of D-17 Reclamation and Soil Conservation Service. Many other agencies, educa¬ tional facilities and private consultants can also provide expert advice. Regardless of where such expertise is based, the qualification of those individuals offering to provide it should be carefully examined and evaluated. 4.3.4. Freeboard Allowances. Guidelines on specific minimum freeboard allowances are not considered appropriate because of the many factors involved in such determinations. The investigator will have to assess the critical parameters for each project and develop its minimum require¬ ment. Many projects are reasonably safe without freeboard allowance because they are designed for overtopping, or other factors minimize possible overtopping. Conversely, freeboard allowances of several feet may be necessary to provide a safe condition. Parameters that should be considered include the duration of high water levels in the reservoir during the design flood; the effective wind fetch and reservoir depth available to support wave generation; the probability of high wind speed occurring from a critical direction; the potential wave runup on the dam based on roughness and slope; and the ability of the dam to resist erosion from overtopping waves. 4.4. Stability Investigations. The Phase II stability investigations should be compatible with the guidelines of this paragraph. 4.4.1. Foundation and Material Investigations. The scope of the foundation and materials investigation should be limited to obtaining the information required to analyze the structural stability and to investigate any suspected condition which would adversely affect the safety of the dam. Such investigations may include borings to obtain concrete, embankment, soil foundation, and bedrock samples; testing specimens from these samples to determine the strength and elastic parameters of the materials, including the soft seams, joints, fault gouge and expansive clays or other critical materials in the foundation; determining the character of the bedrock including joints, bedding planes, fractures, faults, voids and caverns, and other geological irregularities; and installing instruments for determining movements, strains, suspected excessive internal seepage pressures, seepage gradients and uplift forces. Special investigations may be necessary where suspect rock types such as limestone, gypsum, salt, basalt, claystone, shales or others are involved in foundations or abutments in order to determine the extent of cavities, piping or other deficiencies in the rock foundation. A concrete core drilling program should be undertaken only when the existence of significant structural cracks is suspected or the general qualitative condition of the concrete is in doubt. The tests of materials will be necessary only where such data are lacking or are outdated. 4.4.2. Stability Assessment. Stability assessments should utilize in situ properties of the structure and its foundation and pertinent geologic D-18 information. Geologic information that should be considered includes groundwater and seepage conditions; lithology, stratigraphy, and geologic details disclosed by borings, Mas-built" records, and geologic interpre¬ tation; maximum past overburden at site as deduced from geologic evidence; bedding, folding and faulting; joints and joint systems; weathering; slickensides, and field evidence relating to slides, faults, movements and earthquake activity. Foundations may present problems where they contain adversely oriented joints, slickensides or fissured material, faults, seams of soft materials, or weak layers. Such defects and excess pore water pressures may contribute to instability. Special tests may be necessary to determine physical properties of particular materials. The results of stability analyses afford a means of evaluating the structure's existing resistance to failure and also the effects of any proposed modifications. Results of stability analyses should be reviewed for compatibility with performance experience when possible. 4.4.2.1. Seismic Stability. The inertial forces for use in the conven¬ tional equivalent static force method of analysis should be obtained by multiplying the weight by the seismic coefficient and should be applied as a horizontal force at the center of gravity of the section or element. The seismic coefficients suggested for use with such analyses are listed in Figures 1 through 4. Seismic stability investigations for all high hazard category dams located in Seismic Zone 4 and high hazard dams of the hydraulic fill type in Zone 3 should include suitable dynamic pro¬ cedures and analyses. Dynamic analyses for other dams and higher seismic coefficients are appropriate if in the judgment of the investigating engineer they are warranted because of proximity to active faults or other reasons. Seismic stability investigations should utilize "state- of-the-art" procedures involving seismological and geological studies to establish earthquake parameters for use in dynamic stability analyses and, where appropriate, the dynamic testing of materials. Stability analyses may be based upon either time-history or response spectra tech¬ niques. The results of dynamic analyses should be assessed on the basis of whether or not the dam would have sufficient residual integrity to retain the reservoir during and after the greatest or most adverse earthquake which might occur near the project location. 4.4.2.2. Clay Shale Foundation. Clay shale is a highly overconsolidated sedimentary rock comprised predominantly of clay minerals, with little or no cementation. Foundations of clay shales require special measures in stability investigations. Clay shales, particularly those containing montmorillonite, may be highly susceptible to expansion and consequent loss of strength upon unloading. The shear strength and the resistance to deformation of clay shales may be quite low and high pore water pres¬ sures may develop under increase in load. The presence of slickensides in clay shales is usually an indication of low shear stength. Prediction D-19 of field behavior of clay shales should not be based solely on results of conventional laboratory tests since they may be misleading. The use of peak shear strengths for clay shales in stability analyses may be uncon¬ servative because of nonuniform stress distribution and possible progres¬ sive failures. Thus the available shear resistance may be less than if the peak shear strength were mobilized simultaneously along the entire failure surface. In such cases, either greater safety factors or residual shear strength should be used. 4.4.3. Embankment Dams. 4.4.3.1. Liquefaction. The phenomenon of liquefaction of loose, saturated sands and silts may occur when such materials are subjected to shear deformation or earthquake shocks. The possibility of lique¬ faction must presently be evaluated on the basis of empirical knowledge supplemented by special laboratory tests and engineering judgment. The possibility of liquefaction in sands diminishes as the relative density increases above approximately 70 percent. Hydraulic fill dams in Seismic Zones 3 and 4 should receive particular attention since such dams are susceptible to liquefaction under earthquake shocks. 4.4.3.2. Shear Failure. Shear failure is one in which a portion of an embankment or of an embankment and foundation moves by sliding or rotating relative to the remainder of the mass. It is conventionally represented as occurring along a surface and is so assumed in stability analyses, although shearing may occur in a zone of substantial thickness. The circular arc or the sliding wedge method of analyzing stability, as per¬ tinent, should be used. The circular arc method is generally applicable to essentially homogeneous embankments and to soil foundations consisting of thick deposits of fine-grained soil containing no layers significantly weaker than other strata in the foundation. The wedge method is generally applicable to rockfill dams and to earth dams on foundations containing weak layers. Other methods of analysis such as those employing complex shear surfaces may be appropriate depending on the soil and rock in the dam and foundation. Such methods should be in reputable usage in the engineering profession. 4.4.3.3. Loading Conditions. The loading conditions for which the embank¬ ment structures should be investigated are (I) Sudden drawdown from spill¬ way crest elevation or top of gates, (II) Partial pool, (III) Steady state seepage from spillway crest elevation or top of gate elevation, and (IV) Earthquake. Cases I and II apply to upstream slopes only; Case III applies to downstream slopes; and Case IV applies to both up¬ stream and downstream slopes. A summary of suggested strengths and safety factors are shown in Table 4.

See Figures 1 through 4 for Seismic Coeffi¬ cients . Not applicable to embankments on clay shale foundation. Experience has indicated special problems in determination of design shear strengths for clay shale foundations and acceptable safety factors should be compatible with the confidence level in shear strength assumptions. Other strength assumptions may be used if in common usage in the engineering profession. The safety factor should not be less than 1.5 when drawdown rate and pore water pressure developed from flow nets are used in stability analyses. K^/lCy. is the ratio of horizontal to vertical permeability. A minimum of 9 is suggested for use in compacted embankments and alluvial sedi.ments. D-21 *** Use shear strength for case analyzed without earthquake. It is not necessary to analyze sudden drawdown for earthquake loading. Shear strength tests are classified according to the controlled drainage conditions maintained during the test. R tests are those in which specimen drainage is allowed during consolidation (or swelling) under initial stress conditions, but specimen drainage is not allowed during application of shearing stresses. S tests allow full drain¬ age during initial stress application and shearing is at a slow rate so that complete specimen drainage is permitted during the complete test. 4.4.3.4. Safety Factors. Safety factors for embankment dam stability studies should be based on the ratio of available shear strength to developed shear strength, S^: Sp = C + tan fa F . S . F . S . (1) C = cohesion fa = angle of internal friction () = normal stress The factors of safety listed in Table 4 are recommended as minimum accept¬ able. Final accepted factors of safety should depend upon the degree of confidence the investigating engineer has in the engineering data avail¬ able to him. The consequences of a failure with respect to human life and property damage are important considerations in establishing factors of safety for specific investigations. 4.4.3.5. Seepage Failure. A critical uncontrolled underseepage or through seepage condition that develops during a rising pool can quickly reduce a structure which was stable under previous conditions, to a total structural failure. The visually confirmed seepage conditions to be avoided are (1) the exit of the phreatic surface on the downstream slope of the dam and (2) development of hydrostatic heads sufficient to create in the area downstream of the dam sand boils that erode materials by the phenomenon known as "piping" and (3) localized concentrations of seepage along conduits or through pervious zones. The dams most susceptible to seepage problems are those built of or on pervious materials of uniform fine particle size, with no provisions for an internal drainage zone and/or no underseepage controls. D- 22 4.4.3.6. Seepage Analyses. Review and modifications to original seepage design analyses should consider conditions observed in the field inspection and piezometer instrumentation. A seepage analysis should consider the permeability ratios resulting from natural deposi¬ tion and from compaction placement of materials with appropriate variation between horizontal and vertical permeability. An under¬ seepage analysis of the embankment should provide a critical gradient factor of safety for the maximum head condition of not less than 1.5 in the area downstream of the embankment. F.S = ic/i = Hc/Db = Db ^ (2) H/Db h'C i = Critical gradient i = Design gradient H = Uplift head at downstream toe of dam measured above tailwater Hc Db Ym Yw The critical uplift The thickness of the top impervious blanket at the downstream toe of the dam The estimated saturated unit weight of the material in the top impervious blanket The unit weight of water Where a factor of safety less than 1.5 is obtained the provision of an underseepage control system is indicated. The factor of safety of 1.5 is a recommended minimum and may be adjusted by the responsible engineer based on the competence of the engineering data. 4.4.4. Concrete Dams and Appurtenant Structures. 4.4.4.1. Requirements for Stability. Concrete dams and structures appurtenant to embankment dams should be capable of resisting over¬ turning, sliding and overstressing with adequate factors of safety for normal and maximum loading conditions. D- 23 4.4.4.2. Loads. Loadings to be considered in stability analyses include the water load on the upstream face of the dam; the weight of the struc¬ ture, internal hydrostatic pressures (uplift) within the body of the dam, at the base of the dam and within the foundation; earth and silt loads; ice pressure, seismic and thermal loads, and other loads as applicable. Where tailwater or backwater exists on the downstream side of the structure it should be considered, and assumed uplift pressures should be compatible with drainage provisions and uplift measurements if available. Where applicable, ice pressure should be applied to the contact surface of the structure at normal pool elevation. A unit pres¬ sure of not more than 5,000 pounds per square foot should be used. Normally, ice thickness should not be assumed greater than two feet. Earthquake forces should consist of the inertial forces due to the horizontal acceleration of the dam itself and hydrodynamic forces resulting from the reaction of the reservoir water against the structure. Dynamic water pressures for use in conventional methods of analysis may be computed by means of the "Westergaard Formula'1, using the parabolic approximation (H.M. Westergaard, "Water Pressures on Dams During Earth¬ quakes," Trans., ASCE, Vol 98, 1933, pages 418-433), or similar method. 4.4.4.3. Stresses. The analysis of concrete stresses should be based on in situ properties of the concrete and foundation. Computed maximum com¬ pressive stresses for normal operating conditions in the order of 1/3 or less of in situ strengths should be satisfactory. Tensile stresses in unreinforced concrete should be acceptable only in locations where cracks will not adversely affect the overall performance and stability of the structure. Foundation stresses should be such as to provide adequate safety against failure of the foundation material under all loading conditions. 4.4.4.4. Overturning. A gravity structure should be capable of resisting all overturning forces. It can be considered safe against overturning if the resultant of all combinations of horizontal and vertical forces, excluding earthquake forces, acting above any horizontal plane through the structure or at its base is located within the middle third of the section. When earthquake is included the resultant should fall within the limits of the plane or base, and foundation pressures must be accept¬ able. When these requirements for location of the resultant are not satisfied the investigating engineer should assess the importance to stability of the deviations. 4.4.4.5. Sliding. Sliding of concrete gravity structures and of abutment and foundation rock masses for all types of concrete dams should be evaluated, by the shear-friction resistance concept. The available sliding resis¬ tance is compared with the driving force which tends to induce sliding to arrive at a sliding stability safety factor. The investigation should be made along all potential sliding paths. The critical path is that plane or combination of planes which offers the least resistance. D-24 4.4.4.5.1. Sliding Resistance. Sliding resistance is a function of the unit shearing strength at no normal load (cohesion) and the angle of friction on a potential failure surface. It is determined by computing the maximum horizontal driving force which could be resisted along the sliding path under investigation. The following general formula is obtained from the principles of statics and may be derived by resolving forces parallel and perpendicular to the sliding plane: % V tan (^ + ex, ) -f cA cosoc(l - tan b tan oc ) (3) where = Sliding Resistance (maximum horizontal driving force which can be resisted by the critical path) b = Angle of internal friction of foundation material or, where applicable, angle of sliding friction V = Summation of vertical forces (including uplift) c = Unit shearing strength at zero normal loading along potential failure plane A = Area of potential failure plane developing unit shear strength ii c" C* = Angle between inclined plane and horizontal (positive for uphill sliding) For sliding downhill the angle Oc is negative and Equation (1) becomes: R R V tan (b - c* ) + _cA_ cos\X (1 4- tan b tancx ) (4) When the plane of investigation is horizontal, and the angle CX is zero and Equation (1) reduced to the following: R^ = V tan b + cA (5) D- 25 \ 4.4.4.5.2. Downstream Resistance. When the base of a concrete structure is embedded in rock or the potential failure plane lies below the base, the passive resistance of the downstream layer of rock may sometimes be utilized for sliding resistance. Rock that may be subjected to high velocity water scouring should not be used. The magnitude of the downstream resistance is the lesser of (a) the shearing resistance along the continuation of the potential sliding plane until it daylights or (b) the resistance available from the downstream rock wedge along an inclined plane. The theoretical resistance offered by the passive wedge can be computed by a formula equivalent to formula (3): W c* c A W tan + c* ) __ cA_ _ cos^nCT - tan j5~tari oc'7 (6) passive resistance of rock wedge weight (buoyant weight if applicable) of downstream rock wedge above inclined plane of resistance, plus any superimposed loads angle of internal friction or, if applicable, angle of sliding friction angle between inclined failure plane and horizontal unit shearing strength at zero normal load along failure plane area of inclined plane of resistance When considering cross-bed shear through a relatively shallow, competent rock strut, without adverse jointing or faulting, W andcx may be taken at zero and 45°, respectively, and an estimate of passive wedge resis¬ tance per unit width obtained by the following equation: Pp = 2 cD (7) where D = Thickness of the rock strut 4.4.4.5.3. Safety Factor. The shear-friction safety factor is obtained by dividing the resistance Rp by H, the summation of horizontal service D-26 loads to be applied to the structure: Ss-f (8) H When the downstream passive wedge contributes to the sliding resistance, the shear fruction safety factor formula becomes: (9) H The above direct superimposition of passive wedge resistance is valid only if shearing rigidities of the foundation components are similar. Also, the compressive strength and buckling resistance of the downstream rock layer must be sufficient to develop the wedge resistance. For example, a foundation with closely spaced, near horizontal, relatively weak seams might not contain sufficient buckling strength to develop the magnitude of wedge resistance computed from the cross-bed shear strength. In this case wedge resistance should not be assumed without resorting to special treatment (such as installing foundation anchors). Computed sliding safety factors approximating 3 or more for all loading conditions without earthquake, and 1.5 including earthquake, should indicate satisfactory stability, depending upon the reliability of the strength parameters used in the analyses. In some cases when the results of comprehensive foundation studies are available, smaller safety factors may be acceptable. The selection of shear strength parameters should be fully substantiated. The bases for any assumptions; the results of applicable testing, studies and investigations; and all pre-existing, pertinent data should be reported and evaluated. CHAPTER 5 - REPORTS 5.1. General.

D-38 APPENDIX II INSPECTION ITEMS This appendix provides guidance for performing field inspections and may serve as the basis for developing a detailed checklist for each dam. 1. Concrete Structures in General. a. Concrete Surfaces. The condition of the concrete surfaces should be examined to evaluate the deterioration and continuing serviceability of the concrete. Descriptions of concrete conditions should conform with the appendix to ''Guide for Making a Condition Survey of Concrete in Service," American Concrete Institute (ACI) Journal, Proceedings Vol. 65, No. 11, November 1968, page 905-918. b. Structural Cracking. Concrete structures should be examined for structural cracking resulting from overstress due to applied loads, shrinkage and temperature effects or differential movements. c. Movement - Horizontal and Vertical Alignment. Concrete structures should be examined for evidence of any abnormal settlements, heaving, deflections, or lateral movements. d. Junctions. The conditions at the junctions of the structure with abutments or embankments should be determined. e. Drains - Foundation, Joint, Face. All drains should be examined to determine that they are capable of performing their design function. f. Water Passages. All water passages and other concrete surfaces subject to running water should be examined for erosion, cavitation, obstructions, leakage or significant structural cracks. g. Seepage or Leakage. The faces, abutments and toes of the concrete structures should be examined for evidence of seepage or abnormal leakage, and records of flow of downstream springs reviewed for variation with reservoir pool level. The sources of seepage should be determined if possible. h. Monolith Joints - Construction Joints. All monolith and construc¬ tion joints should be examined to determine the condition of the joint and filler material, any movement of joints, or any indication of distress or leakage. i. Foundation. Foundation should be examined for damage or possible undermining of the downstream toe. j D-39 j. Abutments. The abutments should be examined for sign of instability or excessive weathering. 2. Embankment Structures. a. Settlement. The embankments and downstream toe areas should be examined for any evidence of localized or overall settlement, depressions or sink holes. b. Slope Stability. Embankment slopes should be examined for irregu¬ larities in alignment and variances from smooth uniform slopes, unusual changes from original crest alignment and elevation, evidence of move¬ ment at or beyond the toe, and surface cracks which indicate movement. c. Seepage. The downstream face of abutments, embankment slopes and toes, embankment - structure contacts, and the downstream valley areas should be examined for evidence of existing or past seepage. The sources of seepage should be investigated to determine cause and potential severity to dam safety under all operating conditions. The presence of animal burrows and tree growth on slopes which might cause detrimental seepage should be examined. d. Drainage Systems. All drainage systems should be examined to determine whether the systems can freely pass discharge and that the discharge water is not carrying embankment or foundation material. Systems used to monitor drainage should be examined to assure they are operational and functioning properly. e. Slope Protection. The slope protection should be examined for erosion-formed gullies and wave-formed notches and benches that have reduced the embankment cross-section or exposed less wave resistant materials. The adequacy of slope protection against waves, currents, and surface runoff that may occur at the site should be evaluated. The condition of vegetative cover should be evaluated where pertinent. 3. Spillway Structures. Examination should be made of the structures and features including bulkheads, flashboards, and fuse plugs of all ser¬ vice and auxiliary spillways which serve as principal or emergency spillways for any condition which may impose operational constraints on the functioning of the spillway. a. Control Gates and Operating Machinery. The structural members, connections, hoists, cables and operating machinery and the adequacy of normal' and emergency power supplies should be examined and tested to determine the structural integrity and verify the operational adequacy of the equipment. Where cranes are intended to be used for handling gates and bulkheads, the availability, capacity and condition of the cranes and lifting beams should be investigated. Operation of control D-40 systems and protective and alarm devices such as limit switches, sump high water alarms and drainage pumps should be investigated. b. Unlined Saddle Spillways. Unlined saddle spillways should be examined for evidence of erosion and any conditions which may impose constraints on the functioning of the spillway. The ability of the spillway to resist erosion due to operation and the potential hazard to the safety of the dam from such operation should be determined. c. Approach and Outlet Channels. The approach and outlet channels should be examined for any conditions which may impose constraints on the functioning of the spillway and present a potential hazard to the safety of the dam. d. Stilling Basin (Energy Dissipators). Stilling basins including baffles, flip buckets or other energy dissipators should be examined for any conditions which may pose constraints on the ability of the stilling basin to prevent downstream scour or erosion which may create or present a potential hazard to the safety of the dam. The existing condition of the channel downstream of the stilling basin should be determined. 4. Outlet Works. The outlet works examination should include all structures and features designed to release reservoir water below the spillway crest through or around the dam. a. Intake Structure. The structure and all features should be examined for any conditions which may impose operational constraints on the outlet works. Entrances to intake structure should be examined for conditions such as silt or debris accumulation which may reduce the discharge capabilities of the outlet works. b. Operating and Emergency Control Gates. The structural members, connections, guides, hoists, cables and operating machinery including the adequacy of normal and emergency power supplies should be examined and tested to determine the structural integrity and verify the opera¬ tional adequacy of the operating and emergency gates, valves, bulkheads, and other equipment. c. Conduits, Sluices, Water Passages, Etc. The interior surfaces of conduits should be examined for erosion, corrosion, cavitation, cracks, joint separation and leakage at cracks or joints. d. Stilling Basin (Energy Dlssipator). The stilling basin or other energy dissipator should be examined for conditions which may impose any constraints on the ability of the stilling basin to prevent downstream scour or erosion which may create or present a potential hazard to the safety of the dam. The existing condition of the channel downstream of the stilling basin should be determined by soundings. D-41 e. Approach and Outlet Channels. The approach and outlet channels should be examined for any conditions which may impose constraints on the functioning of the discharge facilities of the outlet works, or present a hazard to the safety of the dam. f. Drawdown Facilities. Facilities provided for drawdown of the reservoir to avert impending failure of the dam or to facilitiate repairs in the event of stability or foundation problems should be examined for any conditions which may impose constraints on their functioning as planned. 5. Safety and Performance Instrumentation. Instruments which have been installed to measure behavior of the structures should be examined for proper functioning. The available records and readings of installed instruments should be reviewed to detect any unusual performance of the instruments or evidence of unusual performance or distress of the structure. The adequacy of the installed instrumentation to measure the performance and safety of the dam should be determined. a. Headwater and Tailwater Gages. The existing records of the head¬ water and tailwater gages should be examined to determine the relationship between other instrumentation measurements such as stream flow, uplift pressures, alignment, and drainage system discharge with the upper and lower water surface elevations. b. Horizontal and Vertical Alignment Instrumentation (Concrete Structures). The existing records of alignment and elevation surveys and measurements from inclinometers, inverted plumb bobs, gage points across cracks and joints, or other devices should be examined to determine any change from the original position of the structures. c. Horizontal and Vertical Movement, Consolidation, and Pore-Water Pressure Instrumentation (Embankment Structures). The existing records of measurements from settlement plates or gages, surface reference marks, slope indicators and other devices should be examined to determine the movement history of the embankment. Existing piezometer measurements should be examined 'to determine if the pore-water pressures in the embankment and foundation would under given conditions impair the safety of the dam. d. Uplift Instrumentation. The existing records of uplift measure¬ ments should be examined to determine if the uplift pressures for the maximum pool would impair the safety of the dam. e. Drainage System Instrumentation. The existing records of measure¬ ments of the drainage system flow should be examined to establish the D-42 normal relationship between pool elevations and discharge quantities and any changes that have occurred in this relationship during the history of the project. f. Seismic Instrumentation. The existing records of seismic instru¬ mentation should be examined to determine the seismic activity in the area and the response of the structures to past earthquakes. 6. Reservoir. The following features of the reservoir should be examined to determine to what extent the water impounded by the dam would constitute a danger to the safety of the dam or a hazard to human life or property. a. Shore line. The land forms around the reservoir should be examined for indications of major active or inactive landslide areas and to determine susceptibility of bedrock stratigraphy to massive landslides of sufficient magnitude to significantly reduce reservoir capacity or create waves that might overtop the dam. b. Sedimentation. The reservoir and drainage area should be examined for excessive sedimentation or recent developments in the drainage basin which could cause a sudden increase in sediment load thereby reducing the reservoir capacity with attendant increase in maximum outflow and maximum pool elevation. c. Potential Upstream Hazard Areas. The reservoir area should be examined for features subject to potential backwater flooding resulting in loss of human life or property at reservoir levels up to the maximum water storage capacity including any surcharge storage. d. Watershed Runoff Potential. The drainage basin should be examined for any extensive alterations to the surface of the drainage basin such as changed agriculture practices, timber clearing, railroad or highway con¬ struction or real estate developments that might extensively affect the runoff characteristics. Upstream projects that could have impact on the safety of the dam should be identified. 7. 'Downstream Channel. The channel immediately downstream of the dam should be examined for conditions which might impose any constraints on the operation of the dam or present any hazards to the safety of the dam. Development of the potential flooded area downstream of the dam should be assessed for compatibility with the-hazard classification. 8. Operation and Maintenance Features. a. Reservoir Regulation Plan. The actual practices in regulating the reservoir and discharges under normal and emergency conditions should be D-43 examined to determine if they comply with the designed reservoir regulation plan and to assure that they do not constitute a danger to the safety of the dam or to human life or property. b. Maintenance. The maintenance of the operating facilities and features that pertain to the safety of the dam should be examined to determine the adequacy and quality of the maintenance procedures followed in maintaining the dam and facilities in safe operating condition. « D-44 APPENDIX III Public Law 92-367 92nd Congress, H.

That Dr. Ellis L. Armstrong, his committee and participants in the Conference be complimented for the excellent technical program that was presented and that Dr. Sandford S. Cole and his staff be complimented for supporting the Conference and arranging for the physical facilities and social events. The foreign participants should be especially thanked for traveling the long distance to share their experiences with us. 2. That the determination of the adequacy of new and old dams be based on the application of current standards and methods and that all states should establish a procedure for review of plans and specifications and the issuance of licenses for the construction of new dams and major alterations of old dams. 3. That states should have prime responsibility for inspection and regulation of non-federal dams for safety and that adequate laws should be enacted by states. These laws should include provisions for the establishment of a state program with adequate funds for implementation. For uniformity, use of the concepts of the USCOLD model for the inspection and safety of dams is suggested as a basis for these new laws and for revision of existing laws. 4. That the Corps of Engineers and the Bureau of Reclamation be requested to furnish guidelines for the inspection of dams to interested engineers and that ASCE and USCOLD be requested to establish a joint committee for continuing the development of guidelines for the inspection of dams. 5. That the National Congress and State Legislative Bodies be urged to recognize the significance of well planned and executed inspection, maintenance and repair programs for old dams and that they provide effective financial assistance for such programs to the owners and to regulatory agencies entrusted with enforcement of the programs when the need for financial assistance has been demonstrated. 6. That the proceedings of this Conference be published. 7. That an Engineering Foundation Conference be organized within the next year for the express purpose of considering the unique problems of small dams, with special emphasis on licensing, inspection, maintenance and repair of these dams. 8. That an Engineering Foundation Conference be held two years hence for evaluating the progress made on these resolutions. Also that the chairman for the organizing committee of the next conference be selected within the next 60 days by the organizing committee of this Conference.

That states, in carrying out the prime responsibility for inspection and regulation of non-federal dams for safety, proceed to enact the necessary legislation and to implement promptly an orderly plan, including appropriate levels of funding, for a systematic approach to the inspection, evaluation, maintenance, and rehabilitation of dams across the Nation; 2. That the Secretary of the Army, in making his recommendation to Congress for a national program of inspection of dams in compliance with PL 92-367, include a provision for federal cost sharing. 3. To further the cause for the exchange of information and experience, State agency officials charged with dam safety be encouraged to form a national association. Be it further resolved that the Chairman of this Conference form an ad hoc committee to pursue this goal. 4. That the dissemination of information addressing the issues of dam safety and its relationship to protecting the public be accelerated. Therefore, the proceedings of the conference should be published. The Engineering Joint Council be requested to use its offices to involve its member societies in the issues of dam safety. The public should be made aware by an information program developed by the professional societies to the problems of dam safety. 5. The Engineering Foundation be requested to organize a conference in 1975 as resolved by the 1973 Engineering Foundation Conference on the Inspection, Maintenance and Rehabilitation of Old Dams. This conference should serve to evaluate the progress made on the 1973 and 1974 resolutions. Additional suggested conference topics are adequate funding, legislative support, legal liabilities and evaluation criteria. 6. That Conference Chairman, Commissioner Malcolm E. Graf, his committee, and participants in the Conference be commended for the excellent technical program that was presented and that the sincere appreciation of the conferees be expressed to Dr, Sandford S. Cole and his staff for supporting the conference and arranging for the physical facilities and social events.
