PG&E is proposing to abandon the wells by pressure grouting with <br /> neat cement to the surface. A wellhead pressure of 25 psi will be applied and maintained <br /> for 5 minutes to assure proper sealing. The top three feet of soil will be removed during <br /> the excavation of the well box. <br /> My understanding is that the permit to abandon the wells through San Joaquin County will <br /> cost $375, which we will pay by credit card. Based on soil confirmation sampling <br /> conducted after a remedial removal action, the site has very low concentrations of TPH <br /> below RWQCB action levels. In July 2008, RWQCB concluded that the site does not <br /> present a risk to either human health or the environment and issued a conditional No <br /> Further Action (NFA) for the site. A final NFA determination by RWQCB will be granted <br /> after the onsite monitoring wells have been properly abandoned. To support the SJC <br /> permit application to abandon the monitoring wells please find attached the following: <br /> 1. Signed permit application and Master File Record. <br /> 2. RWQCB NFA Letter, July 2008. <br /> 3. Letter to the RWQCB with an estimate of contaminants remaining in soil and <br /> groundwater, April 2008. <br /> 4. Request for NFA, August 2004, with analytical data and site figures. <br /> 5. Well construction details <br /> Please feel free to contact me if any additional information is needed. <br /> Thank you! <br /> 6r– 4-vJ)reSSare csrom-�- <br /> Michael Schulman <br /> Senior Scientist P2 I <br /> Parsons M LJ l <br /> 2121 North California Blvd, Suite 500 /YttA).X � <br /> Walnut Creek, CA 94596 <br /> Office: (925) 941-3735 <br /> Fax: (925) 979-9781 <br /> michael.schulman@parsons.com 01Jt( ba rc <br /> pZ3 — Sec Sc, [ olwr ]•. i w <br /> p,hl�s<<�on o� EttO�+�C <br /> 9/16/2008 <br />
