<br /> DOCUMENT REVIEW, NEW WEST PETROLEUM #1003 (AKA FLAG CITY SHELL),
<br /> 6437 NORTH BANNER STREET, LODI, SAN JOAQUIN COUNTY, CLEANUP AND
<br /> ABATEMENT ORDER R5•2007-0709 (CASE 391163)
<br /> 1 reviewed the Monitoring Well Destruction Work Plan (Workplan) submitted by email on
<br /> 31 July 2012 by Advanced Geo Environmental Inc. The Workplan proposed the
<br /> destruction of forty two (42) monitoring (MWs) and remediation (EWs or groundwater
<br /> extraction) wells per extensive discussions concerning well destruction methods with
<br /> the San Joaquin County Environmental Health Department and with their written
<br /> approval for the methods listed below. All wells will first have the well completions
<br /> remove to expose the casings. Wells MW-3B, MW-3C, MW-4C, MW-613, MW-6C,
<br /> MW-7B, MW-813, MW-2013, WE-813, and EW-913 will be destroyed by over-drilled to total
<br /> depth and tremie grouting to surface. Wells MW-1, MW-2, MW-3A, MW-513, MW-8A,
<br /> MW-913, MW-9C, MW-9D, MW-10A, MW-10B, MW-10C, MW-10D, MW-11 B, MW-12A,
<br /> MW-13A, MW-13B, MW-19A, MW-19B, EW-1 through EW-5, EW-6A, EW-7A, EW-713,
<br /> and EW-10A will be pressure grouted to surface. Wells MW-4A, MW-7A, and MW-20A
<br /> will first attempt to have the casing and cement grout pulled out and removed as one
<br /> intact unit and if successful, grouted to surface; however, if pulling out the wells casing
<br /> and cement grout as one intact unit is not entirely successful, the well(s) will be over-
<br /> drilled to total depth and grouted to surface. A well destruction report will be submitted.
<br /> The Workplan is approved. Since there was no schedule for the work as directed in my
<br /> 30 January 2012 letter, you will have until 2 November 2012 to submit a well
<br /> destruction report, or until 20 August 2012 to provide a rational for an extension with a
<br /> schedule if unable to meet the 2 November 2012 deadline. Please give the SJCEHD
<br /> and myself at least three working days' notice prior to initiating fieldwork. If you have
<br /> any questions, you can contact me at (916) 464-4615 or I can be reached by e-mail at
<br /> jbartonCcDwaterboards.ca.gov.
