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 (municipal or domestic <br /> well) , the extent of soil contamination, and the site' s clean up funding <br /> availability. <br /> Based upon the priority ranking, you will be directed to begin the required <br /> investigation. However, given the conditions for the 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 information 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 excavat on 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 sail. <br /> A Division of San 402quin County I <br /> e9th Care Services <br />
