Thoroton Rd. RO# :000550 <br /> Lodi, CA.,95242 <br /> San Joaquin CountyPublic Health Services,Environmental Health Division (PIS-EHD) <br /> has reviewed a recently submitted report for the site across the road from you and brings to <br /> your attention some concerns. <br /> The offsite subsurface investigation for the Flag City Chevron station just east of your site <br /> has detected elevated concentrations of petroleum at the west end of your site,near your <br /> above ground storage tanks (AGT). The Total Petroleum Hydrocarbons as Diesel(TPH d) <br /> detected in the groundwater from MW-13B and the MtBE detected in the groundwater from <br /> MW-13A indicate that an isolated source maybe causing this impact to the groundwater in <br /> this area. <br /> PHS-EHD discussed this information with the Central Valley Regional Water Quality <br /> Control Board (CVRWQB) and since this new plume is so close to your drinking water well, <br /> it is necessary to immediately investigate the subsurface conditions in this area. Of particular <br /> concern is the `oil-water separator'located near these monitoring wells and the proximity of <br /> the product lines that come from the AGTs and proceed to your dispenser area. <br /> You are hereby directed to submit a work plan,soil boring/well permit application, <br /> and$89 permit fee to PHS-EHD by August 31, 2000 that proposes boring locations <br /> for delineating the lateral and vertical extents of this contamination. <br /> With both'IPH d and MtBE detected in the groundwater at these monitoring wells,the <br /> proposal should take into consideration that more than one pipeline may be leaking or your <br /> oil-water separator may be allowing captured spilled fuel from the island area to escape to <br /> the environment. Tightness tests may be necessary to show that these systems are not <br /> leaking. <br /> PHS-EHD has noticed that three (3) steel drums labeled"Hazardous Materials" are still <br /> located at the truck entrance to your site. These barrels are to be properly disposed of <br /> immediately and the completed and signed manifest is to be forwarded to PHS-EHD when <br /> the transport to an approved facility is completed. <br /> A Division of San Joaquin County Health Care Services <br />
