I considered driving by this site today but time constraints prevented me from doing <br /> so. <br /> You mentioned that the first application of injecting five percent RegenOx will take place the third week of August. <br /> You will need a boring permit for the 5 boreholes to be injected. I will be on vacation from August 9th through <br /> August 17th, returning to work on August 20th, so I hope you plan to do the injections the week of August 20th. <br /> I will plan to be at the site on August 2nd for the sampling event. What time will the field technician be there? <br /> Our department has approved collecting ambient and indoor air samples every six months after the soil vapor <br /> intrusion mitigation system is in operation, but has not responded to AGE's recommendation to collect crawl- <br /> space samples every six months along with the ambient and indoor air samples. Please note that the <br /> Environmental Health Department approves the collection of the crawl-space sample every six months now that <br /> the system is in operation. <br /> Concerning the sites at 2353 Toste Road in Tracy and 1419 East Charter Way in Stockton, our department has <br /> discussed these sites with Jim Barton and I am preparing Case Closure Summaries for both sites to be sent to <br /> the Regional Board for closure concurrence. <br /> Best Regards, <br /> Vicki McCartney, Senior REHS <br /> San Joaquin County <br /> Environmental Health Department <br /> 1868 East Hazelton Avenue <br /> Stockton, California 95205 <br /> Phone: (209)468-9852 <br /> Email: vmccartney(cDsicehd.com <br /> From: Brian Millman [mailto:bmillman@advgeoenv.com] <br /> Sent: Thursday, July 26, 2012 1:46 PM <br /> To: Vicki McCartney [EH] <br /> Cc: Robert Marty <br /> Subject: LOP Site Updates, Scheduling, and Inquiries <br /> Vicki, <br /> We have not had any contact for a while so I would like to update you on work performed and <br /> upcoming and inquire about the status of a few sites. <br /> Weldon Church_(04 West Beverly Place, Tracy, CA)__ <br /> On 25 June 2012, the soil vapor intrusion mitigation system was installed in the crawl space at <br /> the site and has been operating since then. There was an initial delay in installing the system due <br /> 7/26/2012 <br />
