Purpose of analysis (specify whether Superfund enforcement or remedial action, RCRA, NPDES, etc.): TES V Enforcement, RI/FS Compliance 4. p*timated Date(s) of collection: The samples are scheduled to be collected during the week of September 28, 1992. 5. Estimated date(s) and method of shipment: Samples will be shipped the day they are collected via Federal Express All samples must be refrigerated at 4 degrees Celcius. The laboratory must have personnel available on Saturdays( except legal holidays) to receive, log in and refrigerate samples. The laboratory will be informed by 3 pm on Friday, if Saturday delivery is to be expected. The laboratory shall have all applicable USDA permits including the USDA Compliance Agreement and the Application and Permit to Move soil to allow entry of soil samples into the U.S. from the U.S. VIRGIN ISLANDS. These permits shall be signed by the approprite regulatory officials and legible copies of these documents must be provided to CDMFPC prior to the intial sampling date. 6. Number of days analysis and data required after laboratory receipt of samples: All samples must be analyzed within ten (10) days of verified time of sample receipt. A complete data package containing all the sample delivery groups(SDG's) associated with the case must be submitted in its entirety vithin thirty five(35) days of verified time of sample receipt of the last sample in the case. 7. Analytical protocol required (attached copy if other than a protocol currently used in this program): All samples must be prepared and analyzed per d;t protocols described in Section D, "Analytical Methods for Volatiles" of the current revision of the CLP RAS Statement of Work for Organics analysis OLM01.8, Rev.3/90. Any modifications of the specified procedures must be approved by SHO, prior to sample analysis. TUT 006 1373 - JUL-21-1993 13=39 FROH CDfl-FPC/NYC JQ ti-H-'-. KwHH 8. Special Technical instructions (if outside protocol requirements, specify compound names, CAS numbers, detection limits, etc.); The maximum number of samples in a sample delivery group is 20. All calibration, QA/QC procedures, and analytical procedures as specified in the current revision of the CLP RAS Statement of Work for Organics Analysis OLMO1.8, Rev 3/90 must be performed. In addition to this the laboratory must: 1. Perform Method detection limit studies for the analytes of interest as described in 40 CFR Pt 136, App.B(attached). 2. The analytes of interest must be included in. all calibration standards. 9. Analytical results required (if known, specify format for data sheets, QA/QC reports, Chain-Of-Custody documentation, etc.). If not completed, format of results vill be l«ft to program discretion. Submit all documentation including data sheets vith data results, laboratory duplicate and method blank results, QA/QC information, rav .data, calibration curves, SAS packing lists, chain-of-custody forms, SAS client request form, copy of airbill(s), sample tags, and all CLP deliverable? required for the VOA fraction. The laboratory must submit all supporting documentation to demonstrate the performance of the MDL studies. The complete EPA sample numbers as they appear on chain-of-custody and CLP paperwork, must be used in the raw data and on all data reporting forms. The entire data package must be paginated. Results are to be reported on CLP data forms modified to include the analytes requested in Section 2 of this SAS Request. The laboratory must submit a lab generasted mass spectrum for all compounds detected above and below the detectionn limit stated in the method. A written case narrative describing problems encountered in the receipt of samples or during preparation and analysis and the corrective actions taken must be provided( including telephone record logs, etc.). The case narrative should explain any deviations and their effect on the final results. The data package must be equivalent to the CLP RAS data package as specified in the Statement of Vork for Organics analysis OLH01.8, Rev 3/90. TUT 006 1372 JUL-21-1993 13:40 FROM CDM-FPC/NYC lu crri 10. Other (use additional sheets or attach supplementary information, as needed): The laboratory must provide a detailed example calculation that clearly demonstrates the manner in which the initial and final result vas derived. Where applicable, each component of the calculation must be explained (e.g., if the calculation includes a dilution factor, it must be clear vhere, vhy, and how each dilution occurred). The laboratory must supply any and all information required to produce during independent data reviev, all results reported by the laboratory. Submit sample preparation logs, the concentrations and amounts of standards added for all QC analyses. The laboratory's copy of the SAS request, along vith documentation of any communications vith SMO that resulted in the amendment of the SAS request must be included in the package. 11.

MTBE 10 ug/L* +/- 25% n-propylbenzene 10 ug/L* +/- 25% 1-2-dibromoethane 10 ug/L* +/- 25% * Although these detection limits have been specified, it is recognized that the laboratory vill perform Method Detection Limit studies as specified in Section 8 of this SAS request. 13. QC Requirements All QC requirements are per the current revision of the CLP RAS SOW for Organics OLM01.8, Rev 3/90. MTBE, n-propylbenzene, and 1,2-dibromoethane standards must be added to all calibration standards. System Monitoring Compounds (SMCs) should be added to all samples, blanks, matrix spike, and matrix spike duplicate prior to purging. The SMCs are used to evaluate the purge efficiency.

Action required if limits are exceeded Follow all actions specified in the current revision of the CLP RAS Statement of Work for Organics analysis OLM01.8, Rev 3/90. Failure to obtain method blank values less than the detection limit requires that all samples prepared with that method blank be re-prepared and re-analyzed. All blank data are to be reported and the necessity for re-analysis must be included in the narrative summary. If the duplicate results exceed control limits, re-analyze the sample and the duplicate. If re-analysis fails to produce results in control, contact SMO. Please return this request to the Sample Management Office as soon as possible to expedite processing of your request for special analytical services.
