The site is currently an operating Circle K Service Station and <br /> mini-mart. To meet 1998 UST standards, the USTs and product lines are being <br /> replaced. <br /> In accordance with the work plan on file with San Joaquin County Public Health <br /> Department,Environmental Health Division (SJCEHD) dated October 9, 1997, the <br /> following work will be performed: <br /> 1) the removal of the gasoline underground storage tanks (USTs) and associated product <br /> lines and dispensers; and 2) sampling of soil beneath these facilities to evaluate the <br /> presence of hydrocarbons in soil at the subject site; 3) pumping of groundwater(if <br /> encountered) from UST pit and collection of a groundwater sample; and 4) over- <br /> excavation of hydrocarbon impacted soil to the maximum depth of 25 feet. Applicable <br /> permits for the removal of USTs and product piping will be obtained by Tosco's <br /> contractor prior to the start of any work. New USTs and associated product piping and <br /> dispensers will be installed after the existing facilities are removed. <br /> Work will be performed during weekday daylight hours. Earth moving equipment may <br /> include a backhoe, an excavator, a loader, and other equipment as appropriate. <br /> Excavated soils and debris that contains petroleum hydrocarbons will be temporarily <br /> stored onsite for a maximum of 30 days and covered with plastic sheeting, or with <br /> approval from SJCEHD, hauled to Forward Landfill's holding cell for characterization <br /> prior to disposal at Forward Landfill. Excavation activities will be observed by <br /> SJCEHD and PACIFIC representatives. Soil samples will be collected and analyzed per <br /> SJCEHD requirements. Upon receipt of sample results, PACIFIC will prepare and <br /> submit to SJCEHD a letter report summarizing removal activities and sampling results. <br /> Work is anticipated to commence during October 1997. <br />
