Aurora Street <br /> Stockton CA 95206 <br /> San Joaquin County Public Health Services, Environmental Health Division. <br /> (PHS/EHD) has recently reviewed the analytical results of the soil and/or G <br /> I water samples taken from beneath the undergroundl'storage tank(s) that were/was <br /> removed from this site on May 4, 1992.. <br /> The presence of contaminants at your facility exceed the allowable limits of <br /> leaching potential as recommended by the LUFT Manual 1. The former <br /> underground storage tank(s) (UST) cannot be recommended for final closure <br /> without further investigation to determine the full extent of the soil and/or . <br /> groundwater problem. <br /> PHS/EHD is providing you notification that an "Underground Storage Tank <br /> E Unauthorized Release (Leak) /Contaminated Site Report" has been filed pursuant l <br /> to Section 25295 of the Health and Safety Code (HSC) . ; The appropriate <br /> disclosure of a hazardous waste discharge pursuant to Section 25180.7 of the <br /> Health and Safety Code has been made, and the site ha6' been placed on the list <br /> of contaminated sites in San Joaquin County which is maintained by PHS/EHD. <br /> PHS/EHD has been designated by the State of California Water Resources Control <br /> Board (SWRCB) as the local agency overseeing the investigation of leaking <br />�. USTs. Pursuant to Section 25299 .37 (HSC) , "dischargers" must take corrective <br /> fI action in .response to the unauthorized release. ', <br /> Please be advised that PHS/EHD will be utilizing the SWRCB "Prioritization <br /> System for Leaking Underground Storage Tank Sites" ranking list in order to <br /> prioritize all the contaminated sites. The "Prioritization System{ has <br /> established criteria to distinguish between High Priority Sites, Moderate. <br /> Priority Sites, and Low Priority Sites. Site specific conditions which <br /> influence the placement within the ranking system�are,, for example, depth to <br /> groundwater, proximity to a drinking water source, (mun'icipal or domestic <br /> well) , the extent of soil contamination, and the sites clean up funding ' <br /> availability. <br /> Based upon the priority ranking, you will bedit c <br /> ted to begin the required <br /> investigation. However, given the conditions forlthe prioritization, wherever <br /> possible PHS/EHD will work with you to coincide enforcement directives in <br /> conjunction with secured clean up funding. If you have any questions, contact <br /> the PHS/EHD Site Mitigation Unit for further in£ormati'on at (209) 468-3450. <br /> If your tank removal was recent and you are not planning any remedial <br /> activities within 90 days, the tank excavation should be closed. It has been <br /> our experience that open tank excavations allow for rapid downward migration <br /> of contaminants. Contact the appropriate building department for specific <br /> requirements that may be necessary prior to filling with pea gravel and/or <br /> compacting the tank excavation with clean fill soil. <br /> A Division of San Joaquin County Health Care Services <br />
