WITH people living so <br /> close, a basement right next to the UST pit where people may live or work, and residual soil contamination still <br /> in the area, I'm curious how they will support NO potential for vapor migration affecting the public exists. <br /> mike. <br /> From: Sharla Hardy [mailto:Sharla.Hardy@ci.stockton.ca.us] <br /> Sent: Tuesday, December 14, 2010 10:59 AM <br /> To: Mike Infurna [EH] <br /> Subject: RE: Change Order complete for 601 Main Street LUFT site <br /> Mike, <br /> I've attached the proposal that the change order was based on. Does that seem adequate? <br /> Sharla Hardy <br /> Public Works, City of Stockton <br /> (209) 937-8374 <br /> >>> "Mike Infurna [EH]" <MInfurna@sjcehd.com> 12/14/2010 10:52 AM >>> <br /> Thank you Sharla. <br /> Has AGE discussed the vapor intrusion evaluation with you? UST closures must address the potential for <br /> residual contamination to migrate to the public in the form of soil vapors. It must be either shown (soil <br /> gas samples) or technically justified that any potential migration of contaminated vapors are not/will not <br /> reach the people in the apartments adjacent to the UST pit. <br /> Without actual remediation having occurred at this site, it can be assumed that soil contamination <br /> previously detected at the site still remains. <br /> Check with AGE please to see what plans are in the works..... <br /> thank you <br /> Mike Infurna <br /> 12/14/2010 <br />
