Since you've had communications <br /> with both AECOM (Chevron's consultant) and GeoCon (Stone <br /> Brothers' consultant), I've asked the two firms to work <br /> together on establishing the well abandonment protocol for this <br /> site. That way, you are speaking to Brenda (AECOM) and Josh <br /> (GeoCon) at the same time, eliminating the need to have the <br /> same conversation twice. <br /> Hope this helps streamline the abandonment process and leads to <br /> a clear idea of what is expected in the field. <br /> Thanks, <br /> Stephanie McKenna <br /> Project Manager - Marketing Business Unit <br /> -----Original Message----- <br /> From: Mike Infurna [EH] .[mailto_MInfurna@sicehd.com1 <br /> Sent: Wednesday, August 17, 2011 9:44 AM <br /> To: Jim Barton; McKenna, Stephanie <br /> Cc: Brenda Evans <br /> Subject: RE: 5400 Pacific Avenue Stockton <br /> Thank you Jim. <br /> Ladies and Gentleman, <br /> For your information, I have been in contact with Josh Ewert of <br /> GeoCon regarding which wells will be pressure grouted and which <br /> will have the contents removed. <br /> Including the requirement for monitoring wells #2, 3, & 11 as <br /> listed in the CVRWQCB August 17 letter, I have asked Josh to <br /> provide me a list of ALL of the wells for this site and a <br /> notation next to each as to the method of destruction he would <br /> like to use. I will review this proposal to see if the wells <br /> Josh has proposed for pressure grouting qualify. If they don't, <br /> they will be required to have the contents removed. To qualify <br /> for pressure grouting, the soil, gw, and vapor data indicating <br /> there is no residual contamination present must be available. <br /> Wells with NO data available will be considered UNKNOWN and not <br /> qualified for pressure grout. <br /> Typically, wells of unknown construction, obstructed, <br /> contaminated or in an area of known contamination*, or <br /> incapable of being properly pressure grouted must have the <br /> contents removed. The EHD is mandated by County Ordinance to <br /> require wells to have the contents removed (commonly noted by <br /> consultants and drillers as 'over-bored') if they do not meet <br /> 12/20/2011 <br />
