ATC SITE SAFETY PLAN <br /> FACILITY BACKGROUND <br /> The subject property is located at 1661 Pacific Avenue in Stockton, California near the <br /> southwest corner of Pacific Avenue and Walnut Street. The property contains one existing <br /> structure on the northeast portion of the parcel and the remaining property consists largely <br /> of a parking lot and asphalt surfaced areas. The structure was formerly used as a Bank of <br /> America branch office and is approximately 10,757 square feet in size. The structure is <br /> currently unoccupied, however two automatic teller machines (ATMs) continue to service <br /> bank customers. <br /> In March 1998, ATC performed a Phase I Environmental Site Assessment (ESA) for the <br /> property and the adjacent northern property for SUSD to evaluate the feasibility of title <br /> transfers. <br /> Additionally, the ESA revealed that the former Unocal site to the north of the property has <br /> been adversely affected from on-site activities. Data collected during the ESA indicated soil <br /> and groundwater at the Unocal site has been impacted by leaking underground storage <br /> tanks used to store petroleum products at the site. Environmental investigations have been <br /> performed on the site however petroleum affected soil-and/or groundwater did not appear <br /> to have been fully defined or mitigated to the satisfaction of local and State regulatory <br /> agencies. <br /> WORK PLAN <br /> Task One: <br /> ATC will perform a limited soil gas survey of the site's suspect areas including the <br /> northeastern portion of the subject property bounding the former Unocal site and <br /> the former on-site dry cleaners and paint establishment on the southeastern portion <br /> of the property. Direct push technology will be employed to advance soil gas probes <br /> to desired depths where soil gas will be extracted and sampled. In areas of the <br /> property,which offer only limited access, hand tools will be utilized to drive the gas <br /> collection probe to desired depths. Following laboratory analysis of the collected <br /> soil gas samples, up to four additional soil borings will be advanced at the site to <br /> depths of approximately 20 feet bgs to collect groundwater confirmation samples. <br /> The placement of these borings will be based of the results of the soil gas samples. <br /> PAGE 4 <br />
