The site is a former <br /> Exxon service station and is located at 4444 North Pershing <br /> Avenue, Stockton, California. As part of our remediation <br /> plan, EA has proposed reinjecting treated groundwater to <br /> create a hydraulic barrier between the Exxon site and another <br /> apparent upgradient source of dissolved hydrocarbons. <br /> Following our conversation on May 31, 1991, regarding the role <br /> of the EPA in permitting the injection wells, it was indicated <br /> to me that the Regional Water Quality Control Board (RWQCB) <br /> can be the lead agency for obtaining the necessary permit. <br /> EPA review and concurrence of the permit application is <br /> expected before the reinjection can begin. I have been in <br /> contact with Ms. Pat Leary of the Central Valley RWQCB and <br /> will submit the Waste Discharge Application to Ms. Leary. <br /> Enclosed is a copy of the Workplan to remediate soil and <br /> groundwater at the former Exxon station. As I mentioned <br /> before, EA proposes to reuse the treated groundwater from the <br /> remediation system to reinject into the shallow upper aquifer. <br /> The workplan clearly defines the scope of work for the <br /> remediation system installation and operation. In order to <br /> add these injection wells to the EPA inventory, the soil <br /> boring logs, well completion diagrams and well locations are <br /> provided in the Workplan. <br />
