The site will no longer be operated as a <br /> gasoline service station. The site is bound by an alley to the north,Lodi Avenue to the south, a <br /> ` residential area to the west, and Cherokee Lane to the east. As part of the divestment activities, <br /> all USTs, dispensers, and associated piping were removed from the site. The piping and <br /> dispensers were removed on August 15, 2002, and the USTs were excavated and removed on <br /> ` October 22, 2002. <br /> UST REMOVAL ACTIVITES <br /> Excavation and removal of the USTs, dispensers and piping was performed by K.E. Curtis <br /> Construction Company of Lathrop, California, from August 15, 2002 through October 22, <br /> 2002. The excavated USTs consisted of one split (10,000-gallon and 12,000-gallon capacity) <br /> L fiberglass UST and one 20,000-gallon fiberglass UST. The excavated USTs appeared to be in <br /> good condition, with no apparent holes or cracks visually noted during removal. Excavated soil <br /> was field-screened with a photoionization detector (PID) to determine if impacted soil was <br /> ►� present. No impacted soil was observed or indicated by the PID during the excavation and <br /> removal activities. The removed USTs and piping were transported to Norcal Waste Systems <br /> Pacheco Pass Landfill in Gilroy, California, for proper disposal. Excavation and sampling <br /> r activities were observed and approved by Mr. Dennis Catanyag of the San Joaquin County <br /> Environmental Health Department(SJCEHD). <br /> L <br /> URS Corporation <br /> Crown Corporate Center <br /> V 2870 Gateway Oaks Drive,Suite 300 <br /> Sacramento,CA 95833 <br /> Tel:916.679.2000 <br /> Fax:916.679.2900 K:U5 BP ARCO\00434\UST Removal\UST removal report.doc <br />
