Barton, P.G. <br /> Engineering Geologist <br /> California Regional Water Quality Control Board Central Valley Region, 11020 Sun Center <br /> Drive, Suite 200, Rancho Cordova, CA 95670 office (916) 464-4615 <br /> fax (916) 464-4704 <br /> >>> "Vicki McCartney [EH] " <vmccartney@sjcehd.com> 12/16/2011 11:45 AM <br /> Jim, <br /> An ozone bench scale test was completed at the West Clay Properties site located at 639 <br /> Clay Street in Stockton and you commented on the bench scale test in an email, dated 16 <br /> September 2005, to Bill Little at Advanced GeoEnvironmental, Inc. (AGE) . You copied Jeff <br /> Wong in the email since he was the case worker for this site at that time. I have a copy <br /> of your email if you need it. Our department approved an in-situ ozone injection pilot <br /> study by letter dated 17 April 2006. Ozone injections began in December 2006 and <br /> continued at this site through the fourth quarter 2009. Ozone injections were terminated <br /> at this site in January 2010 . <br /> Our department had asked AGE to provide a feasibility evaluation of ozone injection, air <br /> sparging, and chemical oxidation (such as Regenox) to remediate a another section of this <br /> same site where USTs were also removed. This new section is about 200 feet from the area <br /> where ozone was injected for approximately three years. <br /> Referring only to ozone injection, does your agency require additional evaluation of the <br /> effects of ozone to comply with the terms of General Waste Discharge Requirements and the <br /> Monitoring and Reporting Program or will the original bench scale results suffice? <br /> Vicki McCartney, Senior REHS <br /> San Joaquin County <br /> Environmental Health Department <br /> 600 East Main Street <br /> Stockton, California 95202 <br /> Phone: (209) 468-9852 <br /> Fax: (209) 468-3433 <br /> Email : vmccartney@sjcehd.com <mailto:vmccartney@sjcehd.com> <br /> 1 <br />
