Soil analytical results for the two product USTs (Tank#1 and <br /> Tank#3) were provided to the EHD after their removals on January 24, 1989, but no soil <br /> analytical results are available for review for the waste oil UST (Tank#2) removed on <br /> September 16, 1986. The information is needed before your site can be considered for closure <br /> with no further action required(NFAR). <br /> If the 1986 soil analytical results for Tank#2 are available, please provide them to the EHD for <br /> review. If no results are available to demonstrate that an unauthorized release had not occurred <br /> from UST-2, additional limited groundwater sampling will suffice for evaluation of current <br /> groundwater conditions in the area of the former Tank#2. Groundwater samples should be <br /> collected from monitoring wells (MWs) MW-GT-16A and MW- 31. The groundwater samples <br /> must be analyzed by a California Department of Public Health-certified laboratory using EPA <br /> Method 8260B for volatile organic compounds and EPA Method 8270C for semi-volatile organic <br /> compounds. Please provide the requested information to the EHD by November 1, 2013. <br /> The Central Valley Regional Water Quality Control Board, in addition to the data related to <br /> waste oil USTs, is now reviewing the naphthalene data for sites impacted by diesel releases <br /> before issuing a concurrence letter for site closures. The EHD discussed this data need with <br /> your consultant, who at the request of the EHD was able to have the data extracted from recent <br /> groundwater monitoring events and provided the data to the EHD. The data demonstrates that <br /> naphthalene is not a significant concern on your site and no further analysis for this constituent <br /> is required. <br />
