I have attached our spreadsheet,which is on its way to you <br /> in hardcopy in our report of quarterly monitoring. At this time,we don't propose any further action, but this <br /> well is one that we watch closely. <br /> Please consider this the remediation plan, already implemented. <br /> Best regards, <br /> Mike Carroll <br /> W.Michael Carroll,PE <br /> Senior Civil Engineer,Public Works/Solid Waste <br /> 1810 E Hazelton Way <br /> Stockton,CA 95205 <br /> Phone(Direct):209-468-8504 <br /> Phone(Office Main):209-468-3066 <br /> Fax:209-468-3078 <br /> From: Natalia Subbotnikova [EH] [mailto:nsubbotnikova@sjcehd.com] <br /> Sent: Friday, July 13, 2012 1:53 PM <br /> To: Michael Carroll <br /> Cc: Robert McClellon [EH]; Joyesh Chandra <br /> Subject: Corral Hollow Landfill - GW-6 <br /> Importance: High <br /> Good afternoon Michael, <br /> Just a friendly reminder that Corral Hollow Landfill still under violation for T 27 CCR 20921 —Gas Monitoring and <br /> Control: <br /> Section 20921.
