Ground Zero Analysis, Inc. <br /> SITE SAFETY PLAN <br /> FACILITY BACKGROUND <br /> The parcels were previously part of a Closed, Illegal, and Abandoned (CIA) landfill site <br /> identified by the California Integrated Waste Management Board (CIWMB) as the Snyder <br /> Sanitaa Dump Site. An April 2003 report entitled Site Investigation, Santa Fe Road Disposal <br /> Site, County of San Joaquin, Final Report, summarized a site investigation conducted by the <br /> CIWMB. The objective of the CIWMB investigation was to 1) verify current ownership of all <br /> parcels previously operated as the Snyder Landfill, 2) to determine the horizontal and vertical <br /> extent of thewaste, 3) to characterize the waste via sampling and laboratory analyses, and 4) to <br /> determine the condition of the site with regard to applicable California Code of Regulation, Title <br /> 27 for site security, cover, and drainage and erosion control. The investigation consisted of <br /> excavating numerous trenches on several adjoining_parcels of land, characterizing the soil and <br /> debris encountered in the excavations, monitoring the air for potential contaminants, and <br /> collecting and analog numerous soil samples. No hazardous levels of metals, volatile organic <br /> constituents (VOCs), semivolatile organice constituents (SVOCs,), heave metals, or any other <br /> tested constituent of concern were detected in samples collected from the subject parcels. Based <br /> upon its investigation, the CIWMB concluded that the subject parcels maintained inadequate <br /> cover and drainage and erosion control and failed to meet site security standards outlined in Title <br /> 27. The CIWMB recommended that le above-ground surface wastes be disposed of at a <br /> permitted landfill, 2) buried wastes be consolidated, covered, and graded to meet State Minimum <br /> Standards of Cover, 3) the site be properly secured by fence andatg e to prevent access by <br /> unauthorized vehicles and persons, and 4) additional testing be conducted as necessary during <br /> remediation and appropriate action taken based upon laboratory results. <br /> In a letter dated September 18, 2003, the California Regional Water Quality Control Board, <br /> Central Valley Region(RCB) noted that the results of the investigation demonstrated that the <br /> wastes at the site do not have hazardous waste characteristics. RWQCB staff noted, however, <br /> that soluble lead concentrations in certain samples collected from Parcel 13 exceed the California <br /> Public Health Goal in Drinking water of 2 ug/1, and such soil should be considered designated <br /> waste. <br /> Tentative plans for site remediation of the parcels include excavating debris from certain areas of <br /> each parcel for off-site disposal, consolidating the remaining debris at selected portions of each <br /> parcel, constructingan n engineered cap over the consolidated debris, and providing adequate <br /> drainage/erosion control and site security. A workplan for overall site remediation will be <br /> submitted under separate cover. <br /> PAGE 3 <br />
