UST removal activities were conducted under permit from San Joaquin County Environmental <br /> Health Department(SJCEHD). Soil over-excavation was performed as described in the over-excavation <br /> workplan dated August 6,2002. Copies of the permit and workplan are included in Attachment A. <br /> SITE BACKGROUND <br /> The site is located at 225 South Cherokee Lane in Lodi, California (Figure 1). The site was formerly <br /> operated as an ARCO service station with an AMIPM mini-mart. The site is bounded by an alley to the <br /> north, Lodi Avenue to the south, a residential area to the west, and Cherokee Lane to the east. As part <br /> of divestment activities, all USTs, dispensers, and associated piping were removed during the week of <br /> August 19, 2002. <br /> UST REMOVAL ACTIVITES <br /> Removal of four gasoline USTs, gasoline dispensers, and associated piping was performed by K.E. <br /> Curtis Construction Company of Lathrop, California, during the period of August 15, 2002, through <br /> August 20, 2002. The USTs consisted of four 10,000-gallon capacity fiberglass tanks. The excavated <br /> USTs appeared to be in good condition,with no apparent holes or cracks visually noted during removal. <br /> However, soil staining and a strong petroleum odor were observed in the northeast corner of the UST <br /> excavation. The removed USTs and product piping were transported to Norcal Waste Systems Pacheco <br /> Pass Landfill in Gilroy, California, for proper disposal. Excavation and sampling activities were <br /> observed and approved by Mr.Dennis Catanyag and Ms.Margaret Lagorio of the SJCEHD. <br /> URS Corporation <br /> Crown Corporate Center <br /> 2870 Gateway Oaks Drive,Suite 300 <br /> Sacramento,CA 95833 <br /> Tel:916.679.2000 <br /> Fax:916.679.2900 <br /> KA15 BP ARC0\00760\UST Removal\UST removal 2nd report.doc <br />
