The San <br /> Joaquin County Environmental Health Department (SJCEHD) and the Central Valley Regional <br /> Water Quality Control Board (CVRWQCB) determined that "no further action is required" for <br /> the site and as such requested in a letter dated December 18, 2009 to abandon the existing <br /> monitoring wells at the site. <br /> SITE LOCATION <br /> The site is located on the east side of North West Lane at the intersection of Alpine Avenue in <br /> Stockton, California, as shown on Figure 2. The property is located in a mixed residential, <br /> commercial, and industrial area. The site is currently occupied by a retail gasoline fueling station <br /> and convenience store. <br /> SITE BACKGROUND <br /> In 1997, two 8,000-gallon and one 10,000-gallon underground storage tanks (USTs) and <br /> associated piping and fuel dispensers were removed from the locations shown on Figure 3. Soil <br /> samples were initially collected from the bottom of the tank excavation basin at depths ranging <br /> from 13 to 17 feet below ground surface (bgs). Soil samples were also collected from beneath <br /> the product dispensers and dispensing lines at depths of three to four feet bgs. Soil over- <br /> excavation activities were subsequently conducted on the northwest portion of the UST basin to a <br /> depth of approximately 24 feet bgs due to elevated levels of petroleum hydrocarbons. Analytical <br /> testing of the soil left in place indicated detectable concentrations of petroleum hydrocarbon <br /> constituents and fuel oxygenates, including methyl tert-butyl ether (MTBE) in several samples. <br /> Approximately 400 cubic yards (cy) of soil were removed in conjunction with the UST closure <br /> activity, which was disposed at Forward Landfill in Stockton, California. Three new 10,000- <br /> gallon USTs were installed in the former UST basin. New gasoline product dispensers were <br /> installed within the former western pump island area; however, the southern pump island was <br /> r <br /> Project No.54.26874.0001 <br />
