r F a <br /> REMEDIAL ACTION PLAN ADDENDUM#1 <br /> USA PETROLEUM STATION#65 <br /> FEBRUARY, 1996 <br /> Disposal of Excavated Soil (approx. 4,400 cubic yards) $400,000.00 <br /> Disposal of Demolition Debris, Asphalt and Concrete $ 10,000.00 <br /> The estimated cost for this RAA is estimated to be approximately $ 636,500.00. Please note that <br /> this cost does not include loss of revenue from suspension of retail activities at the site, or the cost <br /> to replace the station and appurtenances. This cost is in addition to the quarterly groundwater <br /> monitoring costs at the site. <br /> RESULTS OF WELL SURVEY <br /> Park approached the City of Lodi (City) to assess the presence of groundwater production wells <br /> in the vicinity of the site. The City indicated that seven groundwater wells were present within a <br /> one-mile radius of the site. The City provided the location and street address for each of the <br /> permitted groundwater wells. The groundwater wells identified by the City and during the <br /> reconnaissance survey are plotted on Figure 1. <br /> Park also performed a reconnaissance level survey in the proximity of the site to identify the <br /> presence of additional groundwater wells within the one-mile radius, but outside of the city limits <br /> to the west of the site. Park observed one potential groundwater well approximately 1,800-feet <br /> west of the site (Figure 1). <br /> DISCUSSION <br /> Since Park submitted the November 20, 1995 RAP, there has been significant activity in response <br /> to the October 16, 1995, Lawrence Livermore National Laboratory (LLNL), "Recommendations <br /> To Improve the Cleanup Process for California's Leaking Underground Fuel Tanks". Numerous <br /> agencies have commented in support of the recommendations in that document. During a <br /> February 6, 1996 telephone conversation with Ms. Margaret Lagoria from the PHS/EHD, Park <br /> was advised that the PHS/EHD had drafted a response to the LLNL report, and that it was being <br /> circulated for internal review. Since that date, Park has inquired as to the status of the document i <br /> and has requested a copy of the draft or final document as soon as it was available. <br /> An analysis of the site conditions and how they relate to the January 5, 1996, San Francisco <br /> Regional Water Quality Control Board's "Supplemental Instructions to State Water Board <br /> December 8, 1995, Interim Guidance on Required Cleanup at Low Risk Sites", suggests that the <br /> USA site may fall into the category of low risk sites. <br /> ff <br /> 4 <br />
