Main Street <br /> Stockton, CA 95202-3029 <br /> Subject: Well Decommissioning and Site Closure Report <br /> PG&E McDonald Island, California <br /> Dear Mr. Knoll: <br /> Please find attached the subject report for your records. This report was prepared by <br /> MSE Group, Pacific Gas and Electric's (PG&E) environmental consultant for the site, <br /> and is being submitted to document well and piezometer decommissioning and other <br /> site closure activities conducted at the PG&E McDonald Island Gas Storage Facility from <br /> May 2009 to September 2009. <br /> For over 13 years PG&E implemented the Monitcring and Reporting Program described <br /> in Waste Discharge Requirements Order No. 96-176 (WDR) issued by the California <br /> EPA Regional Water Quality Control Board — Central Valley Region (CVRWQCB). In <br /> April 2009 the agency rescinded the WDR, thereby concurring with PG&E's conclusion <br /> that contamination by WDR Constituents of Con,-,ern is not currently found in <br /> groundwater at the site or in soil and subsurface water within the footprint of the former <br /> Class II surface impoundments at the site. After WDR rescission, well decommissioning <br /> and site closure were approved contingent on work plan approval and permitting by Sari <br /> Joaquin County Environmental Health Department (SJCEHD). <br /> PG&E is gratified to have completed closure activities at this site and appreciates the <br /> cooperation by both CVRWQCB and SJCEHD. If you have any questions on this report <br /> please call either the undersigned at (925) 415-6381 or Dr. Robert Ellgas of MSE at <br /> (510) 383-9600. <br /> Sincerely, <br /> (li"" <br /> Anne P.
