This case meets all of the required criteria of the Policy. A summary evaluation of <br /> compliance with the Policy is shown in Attachment 1: Compliance with State Water Board <br /> Policies and State Law. The Conceptual Site Model upon which the evaluation of the case has <br /> been made is described in Attachment 2: Summary of Basic Case Information (Conceptual <br /> Site Model). Previous Recommendations are included in Attachment 3: Previous <br /> Recommendations. Highlights of the case follow: <br /> This case is an active commercial petroleum fueling facility in Stockton. An unauthorized release <br /> was reported in June 1997 followed by the removal of three gasoline USTs in February 1998. An <br /> unknown volume of impacted soil was excavated, disposed offsite, and replaced with clean fill in <br /> 1998. Dual phase extraction was conducted between January 2011 and present for a total of <br /> 7,518 hours, which has extracted 199,330 gallons of groundwater and 5224 pounds of total <br /> petroleum hydrocarbons as gasoline (TPHg). The rate of TPHg removal in December 2012 was <br /> approximately 7 pounds per day. Since 1998, 16 groundwater monitoring wells have been <br /> installed and monitored. According to groundwater data, water quality objectives have not been <br /> achieved in the source area. <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 defined plume boundary. No other water supply <br /> wells have been identified within 1,000 feet of the defined plume boundary in files reviewed.
