1 <br /> t <br /> GEO-PHASE <br /> ENVIRONMENTAL <br /> Work Plan <br /> Former UPRR Service Yard ' <br /> 1004 E. Lindsay Avenue <br /> Stockton, CA <br /> (APN#.151-120-50) <br /> March 31, 2003 <br /> d <br /> Project No. 376.2 <br /> z 1.0 INTRODUCTION <br /> The site is located on the western two-thirds of the city block bounded by Lindsay Street, <br /> Miner Avenue, Union Street, and the active Union Pacific Railroad (UPRR) tracks. (See <br /> attached Maps for graphic details). It encompasses a total area of about 1.38 acres. This ' <br /> location exists in an industrial and commercial use area of central Stockton. A recent review <br /> { of various records suggests that a former underground tank site and a former rail spur require <br /> further investigation. San Joaquin County EHD records indicate that a former underground <br /> fuel tank was removed under permit in 1988. A confirmation soil sample contained Iow <br /> levels of Total Petroleum Hydrocarbons. In a follow-up letter, the EHD did not require <br /> additional work to investigate the release, but it also declined to issue a closure certificate. <br /> To obtain final closure of the former tank, we propose to install a soil boring through the <br /> C' former tank pit and to collect a sample of the underlying groundwater (estimated to be about <br /> 30 feet below grade). We also propose two soil borings to further assess soil conditions <br /> f under the former rail spur. <br /> 2.0 PROPOSED INVESTIGATION <br /> To assess sub-surface environmental conditions of a part of the Property, and to define the <br /> vertical extent of what appears to be a small release from a former underground tank, Geo- <br /> Phase Environmental Inc. proposes to install three Geo-Probe soil borings to collect soil and <br /> groundwater samples from the shallow sub-surface of the Property. One of the borings will <br /> be installed near the storage repair shop through the former tank pit, and two borings will be <br /> 2937 Veneman Avenue, Suite$240 Geo-Phase Environmental Inc.
