Proposed Plan Fort Segarra Flamingo Bay Landfill and Test Areas April 2020 Water Island, U.S. Virgin Islands U.S. Army Corps of Engineers, Formerly Used Defense Sites Program Proposed Plan for the Fort Segarra Flamingo Bay Landfill and Test Areas Munitions Response Site 01, Water Island, U.S. Virgin Islands Formerly Used Defense Sites Project Number I02VI097701 April 2020 Text in bold italics indicates that a word or phrase is included in the glossary at the end of this Proposed Plan. INTRODUCTION AND PURPOSE The U.S. Army Corps of Engineers (Corps) is present- ing this Proposed Plan to allow the public the oppor- tunity to review and comment on the recommended ac- tion for Fort Segarra Flamingo Bay Landfill and Test Areas (Munition Response Site 01) and to encourage community participation in the environmental process. This Formerly Used Defense Site, comprising 17 acres, is in the southern portion of Water Island in the U.S. Virgin Islands (see Figure 1). The U.S. Virgin Is- land government and private individuals and businesses own the land comprising Water Island. The anticipated future use is the same (residential with some commer- cial and government use). Based on the findings of the Remedial Investigation and previous studies, the Corps has determined there is no hazard or risk to people or the environment from munitions, munitions constitu- ents (the metals and explosives that comprise muni- tions), chemical warfare materiel, or chemical agents associated with Fort Segarra. This Proposed Plan provides a brief description of the Remedial Investigation. It also provides the basis for supporting the selection of the Preferred Alternative. The Corps will select a final remedy for the site after reviewing and considering the information submitted during the public comment period. The Corps may modify the Preferred Alternative or select another re- sponse action based on new information or public com- ments. Therefore, we encourage the public to review and comment on this Proposed Plan. The Corps is required under the Comprehensive Environmental Response, Compensation, and Liabil- ity Act to issue this Proposed Plan and seek public comment and participation under Section 300.430(f)(2) of the National Oil and Hazardous Substances Pollution Contingency Plan. The Reme- dial Investigation report, which was prepared based on information contained in historical documents and previous studies, forms the basis for the Proposed Plan recommendation. This Proposed Plan sum- marizes information that can be found in greater detail in the Remedial Investigation report and other project documents available for review at the Formerly Used Defense Site Program website: www.saj.usace.army.mil/FortSegarra.

The Corps will consider the public comments on the Preferred Alternative before select- ing and approving a final remedy for the Fort Segarra Flamingo Bay Landfill and Test Areas. The Army is the lead agency for the For- merly Used Defense Sites Program. The Corps, on behalf of the Army and the De- partment of Defense, is the executing agent for the program and is responsible for envi- ronmental restoration of properties that were formerly owned, leased, or otherwise possessed by the United States under the ju- risdiction of the Secretary of Defense. The Corps is responsible for investigating, re- porting, and implementing remedial action for Fort Segarra. The U.S. Virgin Islands Department of Planning and Natural Resources is the regu- latory agency for this project. Representa- tives from the agency reviewed the Reme- dial Investigation report and agreed with its conclusions and recommendations. The Remedial Investigation report is part of the Administrative Record file that contains the documents used in making decisions for Fort Segarra. The Administrative Record file is available for review at the Fort Segarra website (www.saj.usace.army.mil/FortSegarra). This Proposed Plan identifies and provides the basis for selection of the Preferred Alternative. The pur- poses of this Proposed Plan are to: • Provide information about the site, its history, and current and future use. • Identify and describe the Preferred Alternative and explain the reasons for the preference. • Encourage public review and comment on the alternative described. • Provide information on how the public can be involved in the decision-making process.

Con- struction of Fort Segarra started in 1944, with a battery on the southern tip of Water Island to defend the Roosevelt Roads Naval Facility on Puerto Rico. While the concrete gun positions and supporting build- ings were completed, the guns were never installed, and the fort was deactivated in 1946. The U.S. Army Chemical Corps used portions of Wa- ter Island from 1948 to 1950 for limited testing and stor- age of chemical munitions as part of the San Jose Pro- ject. Six tests were con- ducted on Water Island. These included tests with bombs filled with chemical agents. In 1950, the San Jose Project operations were moved to Dugway Proving Ground in Utah. Fort Segarra Flamingo Bay Landfill and Test Areas is comprised of four non-con- tiguous areas that were used in conjunction with the mili- tary’s testing activities on Water Island. The four ar- eas include the Flamingo Bay Landfill Area and Test Areas 4, 5, and 8. In 1952, Water Island was permanently transferred to the U.S. Department of the Interior, who subse- quently leased the island to a private party for two 20-year terms for development as a resort area. The Water Island Hotel was in use from 1954 until 1989, when Hurricane Hugo badly damaged the hotel and it never reopened. After transfer of Water Island from the U.S. Department of the Interior to the U.S. Virgin Islands government in 1996, the hotel and associated structures were demolished. In November 2014, a lease was issued for a new hotel/resort development at the former hotel location and in other ar- eas of Water Island, including Test Areas 4 and 5 and the Flamingo Bay Landfill Area. Additional resi- dential development has also taken place on the island over the last 10 years. The current residential and planned hotel/resort use is expected to remain the same in the future. In September 2017, Hurricanes Irma and Maria caused wide-spread damage to the island. Previous Studies and Investigations The Corps completed a series of studies and investigations at the site to determine the potential presence of munitions, munitions constituents, chemical warfare materiel, and chemical agents following the Figure 3: Fort Segarra Flamingo Bay Landfill and Test Areas Site Details Proposed Plan Fort Segarra Flamingo Bay Landfill and Test Areas April 2020 Water Island, U.S. Virgin Islands Comprehensive Environmental Response, Compensation, and Liability Act process, including the fol- lowing. • Inventory Project Report (1989) – This report documents that 500 acres at Water Island were eli- gible for the Formerly Used Defense Sites Program. While the visual survey completed in con- junction with the report did not identify evidence of munitions, munitions constituents, chemical warfare materiel, or chemical agents, it recommended that an investigation be conducted at the Flamingo Bay Landfill Area where several possible chemical bombs were found in 1966. • Archives Search Report (1991) – The Corps completed this report to determine if sites used by the U.S. Army Chemical Corps for the San Jose Project, including Water Island, were contami- nated by munitions or chemical warfare materiel. The report provides a description of the site, history of use, and findings for the visual survey and interviews conducted for the report. While no physical evidence or documentation was found indicating the presence of munitions or chemi- cal warfare materiel, the report determined there was a potential for their presence and recom- mended additional investigations. • Photo Analysis (1991) – The Corps analyzed aerial photographs from 1948, 1954, and 1958 and determined that there was only one area identified, located in Test Area 5, which may have been used for testing and possible disposal. • Scoping Study (1993) – This document provides additional information regarding the U.S. Army Chemical Corps’ activities at the site based on archival research and interviews with former Chemical Corps personnel. The interviews indicate that the six tests conducted at Fort Segarra in conjunction with the San Jose Project were controlled, well-documented, and decontamination occurred after each test. Furthermore, the types and limited numbers of test items used allowed for easy removal after the testing was complete. The study confirmed that chemical warfare ma- teriel was removed following completion of the project, no further investigation was needed for most areas at Water Island, and an additional investigation was recommended for only Test Ar- eas 4 and 5 and the Flamingo Bay Landfill Area. • Site Characterization - Phase I Remedial Investigation Report (1995) – Site characterization and debris removal operations were conducted in 1993 and 1994 at Water Island, including at Test Areas 4, 5, and 8, and the Flamingo Bay Landfill Area. The characterization activities included surface inspections, magnetometer sweeps and surveys, and investigation to find munitions and chemical warfare materiel, and soil sampling for chemical agents. While there were no muni- tions, chemical warfare materiel, or munitions debris found and no chemical agents were de- tected in the surface soil samples, an additional investigation was recommended for portions of Test Areas 4 and 5, and the Flamingo Bay Landfill Area. • Historical Photo Analysis (2001) – The Corps analyzed historical aerial photographs of Water Island to identify areas where chemical warfare materiel testing potentially took place, with a fo- cus on Test Areas 4 and 5 and the Flamingo Bay Landfill Area. • Revised Archives Search Report (2002) – This report summarizes the additional archival re- search, interviews, aerial photographic analysis, and a site visit that focused on historical muni- tions and chemical warfare materiel use at the site. Although potential munitions related activi- ties were noted for two batteries and Test Area 4, the report confirms that guns were never in- stalled at the batteries and munitions and munitions debris were not found at Test Area 4. No further action was recommended for munitions. The report also documents the chemical warfare materiel used and removed from the site in conjunction with the San Jose Project and concluded that there was no contamination associated with the U.S. Army Chemical Corps’ activities. Proposed Plan Fort Segarra Flamingo Bay Landfill and Test Areas April 2020 Water Island, U.S. Virgin Islands • Engineering Evaluation/Cost Analysis (2005) – This evaluation and analysis included soil sam- pling at Test Areas 4, 5, and 8, and the Flamingo Bay Landfill Area, including 46 test pits, 17 trenches, 88 soil samples, and 8 background soil samples. No munitions or chemical warfare materiel were identified, and the only chemical warfare materiel-related items were scrap metal found at the Flamingo Bay Landfill Area. No munitions constituents or chemical agents were detected in the soil samples. • Engineering Evaluation/Cost Analysis Action Memorandum (2006) – This memorandum recom- mended removing the scrap metal identified at the Flamingo Bay Landfill Area during the 2005 investigation and implementing site-wide institutional controls for Fort Segarra. • Site Specific Final Report (2009) – This report documents removal of the scrap metal from the Flamingo Bay Landfill Area and installation of two signs describing the historical chemical war- fare materiel testing done on Water Island as site-wide institutional controls. • Five-Year Review Report (2012) – This report concluded the activities the Corps completed, in- cluding removing the scrap metal and installing the signs, were protective of human health and the environment. The report also documented that there were no reported incidents involving munitions, chemical warfare materiel, or munitions debris at the site during the five-year review period. • Revised Inventory Project Report (2013) – This document revised the Inventory Project Report to change the size and scope of Munitions Response Site 01 to 17.1 acres and added Test Areas 4, 5, and 8 to the Flamingo Bay Landfill Area. • Site Specific Final Report (2016) – This report documented the replacement of the two informa- tional signs on Water Island. Additional historical documents and studies were also completed for the site, including the following. • San Jose Project Progress Reports (1947-1950) – The progress reports document the chemical warfare materiel testing completed from November 1947 through March 1950, including testing that took place at Water Island. • Navy Report Regarding Ordnance Discovery at Flamingo Bay Landfill (1966) – The Navy Re- port noted several metal objects found during a dredging operation at the Flamingo Bay Landfill Area in 1966. The metal objects were identified as possible chemical bombs. The report stated there was no noticeable release of chemical agent. • Environmental Assessment (1995) – This report presented the findings from a site inspection of Test Areas 4 and 5 and the Flamingo Bay Landfill Area. While abandoned vehicles and house- hold and construction debris were noted in multiple locations, no munitions or chemical warfare materiel were observed. • Preliminary Assessment (2001) – The Department of Interior completed a Preliminary Assess- ment on non-munitions related activities at the site from 1952 to 2001. Although non- munitions related activities did not require further investigation, soil sampling was recommended in con- junction with the site’s former use for chemical warfare materiel testing. • Site Investigation Report (2004) – The Department of Interior conducted a Site Investigation in conjunction with the fieldwork for the 2005 Engineering Evaluation/Cost Analysis. They col- lected soil samples from Test Areas 4, 5, and 8 and the Flamingo Bay Landfill Area and ana- lyzed them for explosives, chemical agents, and other non-munitions related chemicals. The re- sults indicated there was no potential risk to human health or the environment in Test Areas 4, 5, and 8, and the Flamingo Bay Landfill Area, and no further investigation was required. Proposed Plan Fort Segarra Flamingo Bay Landfill and Test Areas April 2020 Water Island, U.S. Virgin Islands Based on the historical documents and previous studies, there is no evidence of munitions use at Fort Segarra. The guns were never installed; there is no documentation of conventional munitions use, and neither munitions nor munitions debris has been found within Flamingo Bay Landfill and Test Areas. Since there is no evidence of munitions use, there is no source for munitions constituents. Historical documents indicate that only six chemical warfare materiel tests were completed or partially completed on Water Island before the testing program was moved to Utah. Chemical warfare materiel associated with the testing included chemical-filled bombs and smoke pots. Although a few suspected chemical warfare materiel-related items were found within Fort Segarra, the items did not contain chemical agents and were removed; none have been found since 1994. Remedial Investigation While numerous studies and investigations had been conducted, a Remedial Investigation was needed, as required by the Comprehensive Environmental Response, Compensation, and Liability Act. As such, the Remedial Investigation report was prepared to document the types, densities, and distribution of, or in the case of Fort Segarra, the lack of evidence of munitions, chemical warfare materiel, munitions con- stituents, and chemical agents. The Remedial Investigation was completed using the information pre- sented in the previous studies and investigations; no additional field work was needed. The Remedial Investigation substantiates the conclusion that munitions, chemical warfare materiel, munitions constitu- ents, and chemical agents do not exist within Flamingo Bay Landfill and Test Areas and, since there is no source, pathways for receptors are incomplete. More specifically, no munitions or munitions constituents are expected at Fort Segarra since construc- tion of the fort was not completed prior to the end of World War II, and no guns were installed. Addi- tionally, no training using munitions was conducted on Water Island. Chemical agent and munitions constituent sampling has confirmed that no chemical agents and explo- sives are present, and metals are not present above regulatory screening values. Although limited chem- ical warfare materiel and chemical agent use is documented, previous studies and investigations con- firmed that the few chemical warfare materiel-related items found on Water Island were free of chemical agents. These items were removed and disposed of offsite. As such, no chemical warfare materiel or chemical agents remain at Fort Segarra. SCOPE AND ROLE OF THE RESPONSE ACTION The overall remedial strategy for Fort Segarra is to eliminate unacceptable risks to human health and the environment due to the military’s past use of the site. Because there is no evidence of munitions or chemical warfare materiel at the Flamingo Bay Landfill and Test Areas, no response action is required. SUMMARY OF SITE RISKS Based on the Remedial Investigation, there is no unacceptable risk to human health or the environment attributable to the Department of Defense at the Fort Segarra Flamingo Bay Landfill and Test Areas. Hazards and risks were evaluated based on the potential for people and the environment to be exposed to munitions, munitions constituents, chemical warfare materiel, and chemical agents. The potentially ex- posed population includes all those who pass through, work in, or visit the area. REMEDIAL ACTION OBJECTIVE Since no remedial action is required, there is no remedial action objective. SUMMARY OF ALTERNATIVES The Preferred Alternative for this site is No Action. The Corps did not develop or evaluate other alter- Proposed Plan Fort Segarra Flamingo Bay Landfill and Test Areas April 2020 Water Island, U.S. Virgin Islands natives because there is no unacceptable risk to human health or the environment attributable to the De- partment of Defense. This alternative means that the Corps will not take any action, and if the Preferred Alternative of No Action is implemented, the use of the site will continue in its current condition. EVALUATION OF ALTERNATIVES There are no risks to human health or the environment attributable to the Department of Defense within Flamingo Bay Landfill and Test Areas. For this reason, the only recommended alternative is No Action. Development or evaluation of other alternatives was not required. PREFERRED ALTERNATIVE No Action is the Preferred Alternative for Flamingo Bay Landfill and Test Areas. It is appropriate be- cause there are no hazards or risks to human health or the environment attributable to the Department of Defense. COMMUNITY PARTICIPATION The Corps is requesting public comments on this Proposed Plan. Comments will be accepted through- out the public comment period (from May 28, 2020 through July 6, 2020).
