redeveloped as a Payless ShoeSource shoe store which operated until a corporate restructuring resulted in closure of the store in May 2017. The Phase I identified the following recognized environmental condition (REQ: • According to available historical sources, the Site was formerly occupied by two generations of gasoline service stations. The first service station was identified at the historical Site address of 1401 California Street and occupied a small portion of the Site in the northeast corner from at least 1935 until at least 1946. The 1940 aerial photograph depicted a structure within the northeastern corner of the Site which appears typical of a gasoline service station. The approximate location of the first service station in depicted in Figure 2. Partner obtained site plans showing that Shell Oil Company developed and operated a gasoline and service station covering a majority of the Site from at least 1968 until circa 1983. No information pertinent to the status of UST systems and/or the removal of USTs was identified on file with the State or local regulatory agencies consulted during and after completion of the Phase I. Additionally, no documentation was available indicating whether soil samples had been collected and analyzed for the presence of petroleum hydrocarbons, as this was not a common practice at the time the gasoline service stations were decommissioned. Based on the absence of documentation related to UST closure and removal, and the absence of previous subsurface investigations that could confirm the presence or absence of a release of hazardous substances and/or petroleum products from the former gasoline service station operations on the Site, the presence of the former gasoline service stations and presumed storage of petroleum products in USTs was considered a REC. Partner performed a Phase 11 Subsurface Investigation Report(Phase II), dated September 12, 2017. Partner performed the Phase II to identify the potential location of on-site LISTS,former tankholds, and/or other associated features and to investigate the potential impact of petroleum hydrocarbons and fuel-related VOCs to soil and/or groundwater as a consequence of a release or releases from the historical on-site gasoline service stations. The scope of the Phase 11 included a geophysical survey employing ground penetrating radar (GPR) for the purpose of identifying subsurface anomalies associated with the former gasoline station operations, and the advancement of five borings (B1 through B5) for the collection of representative soil and/or groundwater samples. The geophysical survey did not identify the presence of existing USTs, Additional Site Assessment Work Plan Heliostockton Property 434 Dr.Martin Luther King Jr.Boulevard Stockton,California Partner Project Number SM17-191672 RWQCB Case#:392004 January 9,2018 Page 4
