The addendum changes the methodology to destroy the 3 deeper <br /> wells using pressure grouting instead of over drilling. The pressure grouting methods <br /> incorporate the San Joaquin County Well Standards (February 2005) , as discussed between <br /> Frank and Roger Lucich. <br /> Please let us know if you have any questions. We are still planning to commence the well <br /> destruction work this Wednesday (June 4) , so your prompt review and approval of this work <br /> plan is appreciated. <br /> Thanks <br /> Mark <br /> -----Original Message----- <br /> From: Kristin Shelton [mailto:Kshelton@waterboards.ca.gov] <br /> Sent: Thursday, May 29, 2008 8:54 AM <br /> To: Wuttig, Mark/THO <br /> Cc: Lucich, Roger/BAO; OsbornS@kindermorgan.com; fgirardi@sjcehd.com <br /> Subject: Re: Holt Well Destruction <br /> Hello Mark - <br /> As we discussed the morning, I concur with your proposal to pressure grout N-21, N-22, and <br /> N-23 in place. KMEP should remove the top five feet of casing as required by SJCEHD and <br /> obtain the appropriate well <br /> destruction permits. <br /> Kristi Shelton <br /> Water Resources Control Engineer <br /> California Regional Water Quality Control Board - Central Valley <br /> Phone: 916-464-4819 <br /> Fax: (916) 464-4797 <br /> Email: kshelton@waterboards.ca.gov <br /> >>> <Mark.Wuttig@CH2M.com> 5/27/2008 4:42 PM >>> <br /> Kristi, <br /> As we discussed, we are currently working with San Joaquin County Environmental Health <br /> Department (EHD) to obtain their required permits for destruction of the 10 soil vapor <br /> extraction wells (VEW-1 through <br /> VEW-10) and 3 deeper groundwater monitoring wells (N-21, N-22, N-23) at the Holt Release <br /> Site. The wells are being abandoned in accordance with CH2M HILL's work plan (dated <br /> November 1, 2007) as conditionally approved by the RWQCB. We are scheduled to perform the <br /> well destruction activities next week from June 4-6. Gregg Drilling and Testing is <br /> scheduled to perform the work under our oversight. <br /> We are requesting a change in well destruction methodology for the 3 deeper wells. Our <br /> work plan stated that we would over-drill the wells and grout the original boreholes to <br /> surface. This is feasible for the shallow SVE wells but not the deeper wells. The deeper <br /> wells are constructed with 8-5/8" steel conductor casings grouted inside 15" <br /> diameter boreholes to approximately 301 . The 2" PVC well casings are grouted inside the <br /> 8-5/8" conductor casing. Removal of the 8-5/8" <br /> 2 <br />
