This report has been <br /> prepared in accordance with guidelines for a no-further-action-request(NFAR)provided in California <br /> Regional Water Quality Control Board(RWQCB) guidelines, and in accordance with a letter dated May <br /> 26, 2009, from the San Joaquin County Environmental Health Department(SJCEHD)concurring with <br /> URS'recommendation that preparation of such a report is now appropriate. <br /> ` 1.1 PURPOSE <br /> This report summarizes site information relevant to obtaining closure for the Site. This information has <br /> been compiled from data developed from previous investigations at the Site conducted by URS,Dames& <br /> Moore,Kleinfelder, Lucy, and Bechtel National, Inc, <br /> 1.2 REPORT ORGANIZATION ' <br /> The format of this NFAR is based on the RWQCB guidance-document Tri-Regional Board Staff <br /> Recommendations for Preliminary Investigation and Evaluation of Underground Tank Sites, Appendix A <br /> - -Reports(RWQCB, 2004). Section 6.6 of that document lists 20 items of information that must be <br /> covered by an NEAR for cases where_ the concentration of remaining`constituents exceed water quality <br /> objectives.The following provides a brief narrative summafry: for each numbered item in Section 6.6, <br /> together with a reference to the section number of this NFAR that includes the supporting information. <br /> 1. Site history (Section 2.2,Site Use History and 2.3,Site Environmental Investigation History) and <br /> current site conditions (Section 3.3, Groundwater) <br /> i <br /> 2. Site geology and hydrogeology. (Section 3.1) <br /> F11 <br /> 3. Sensitive potential receptors including water supply wells and surface water (Section 3.2, <br /> Groundwater Use,Section 2.1,Site Setting) <br /> F7 - 4. Provide a map showing the location of water supply wells within 2,000 feet of the Site. (Section 3.2, <br /> L Groundwater Use) <br /> 5. Provide scaled maps of the area impacted showing locations of former and existing tank systems, <br /> excavation and sample locations, groundwater elevation contours, subsurface utilities,buildings, <br /> _- streets,and any nearby surface waters. (Figure 2,Site Map and Cross Section A A'Location, and <br /> Figure 4, Groundwater Elevation Contour Map,June 6,2009) <br /> f 6. Provide boring logs and cross sections to show Site lithology(Appendix A. Boring Logs, Figure 3, <br /> Litholo is Cross Section) <br /> ) <br /> 7. Report the volume of excavated soil disposed of off-site, or remaining on-site (Section 4.1, <br /> Corrective Actions) <br /> 8.
