This case does not meet all of the required criteria of the Policy. A summary <br /> evaluation of compliance with the Policy is shown in Attachment 1: Compliance with State <br /> Water Board Policies and State Law. The Conceptual Site Model upon which the evaluation of <br /> the case has been made is described in Attachment 2: Summary of Basic Case Information <br /> (Conceptual Site Model). Highlights of the case follow: <br /> This case is an active business. Excavation was conducted to a total depth of 15 feet during the <br /> tank removal in 1985 though the unauthorized release was not reported until April 1988. Soil vapor <br /> extraction was conducted between December 2010 and August 2011, which reportedly removed <br /> approximately 8,258 pounds of total petroleum hydrocarbons as gasoline (TPHg). Since 2004, six <br /> groundwater monitoring wells have been installed and regularly monitored. According to <br /> groundwater data, water quality objectives have been achieved or nearly achieved except in the <br /> source area well MW-5. <br /> The petroleum release is limited to the soil and shallow groundwater. According to data available <br /> in GeoTracker, there are no supply wells regulated by the California Department of Public Health <br /> or surface water bodies within 1,000 feet of the Site. No other water supply wells have been <br /> identified within 1,000 feet of the Site in files reviewed. Water is provided to water users near the <br /> Site by the Stockton East Water District and by the California Water Service. <br /> FELICIA MARCLS,CHAIR I THOMAS HOWARD,EXECUTIVE DIRECTOR <br /> 1001 1 Street,Sacramento,CA 95814 I Mailing Address:P.O.Box 100,Sacramento,C895812-0100 I www.waterboards,ca.gov <br /> a1 R C.aEO PAPER <br />
