Page 3 of 4 <br /> low <br /> ... <br /> Subject: RE: Weldon Church Crawl Space Air Sampling <br /> Hi Brian, <br /> According to the work plan that was approved by this agency, AGE proposed to collect indoor air <br /> samples and ambient air samples every six months after start-up of the vapor intrusion mitigation <br /> system. There was no mention of collecting a crawl space air sample. I have discussed this matter <br /> with Nuel Henderson and we both agree that indoor air, ambient air and at least one crawl space <br /> sample should be collected since it has been over a year since the vapor mitigation system began <br /> operating at the Weldon Church site at 104 West Beverly Place in Tracy. I definitely would like to be <br /> present when these air samples are collected. Thank you. <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: vmccartneyCasicehd.com <br /> d <br /> From: Brian Millman [mailto:bmillman(s:i)advgeoenv.com] <br /> Sent: Thursday, August 01, 2013 11:52 AM <br /> To: Vicki McCartney [EH] <br /> Subject: Weldon Church Crawl Space Air Sampling <br /> Vicki, <br /> Good afternoon Vicki, I would like to schedule a crawl space air sampling event at <br /> 104 West Beverly Place, Tracy, CA. The vapor mitigation system has now been <br /> operating for over a year (operation began in June 2012). The original plan was to <br /> collect a crawl space air sample after 6 months of operation and/or 1 year of <br /> operation; a sample wasn't collected after 6 months due to budget constraints. <br /> I have not scheduled the event with the property owner yet, but I did procure the <br /> equipment so it can be performed sometime next week. Do you want to be onsite for <br /> the sampling event/when I place the canister in the crawl space? If you do I will <br /> contact you either tomorrow or Monday to let you know what day it will be; if not, I will <br /> coordinate with the property and get it done sometime next week (but I will still <br /> contact you and tell you what day we will be placing the canister). <br /> Thanks, <br /> Brian W.
