Monitoring Well Destructions Work Plan 7 September 2016 <br /> Former Holly Sugar Facility Page 2 <br /> 20500 Holly Drive <br /> Tracy, California <br /> Langan Project: 731575102 <br /> • Over-drilling four 4-inch diameter PVC wells to 21, 31, 36, and 45 feet below ground <br /> surface (bgs). <br /> • Over-drilling three 6-inch diameter PVC wells to 33, 35, and 100 feet bgs. <br /> • Tremie grouting each of the seven drilled-out wells to surface with neat cement grout. <br /> • Surface completion will consist of native soil from the well area. <br /> Our work plan includes the following assumptions: <br /> • Over-drilling and grouting the seven wells will be completed within 3'/2 days. <br /> • Cuttings generated during over drilling activities will be spread around the site. <br /> • Debris generated during well abandonment (grout, well casing, and well boxes) will be <br /> drummed up and disposed as construction waste or scrap metal, respectively, with no <br /> special handling requirements. <br /> REPORTING <br /> Langan will prepare a well destruction completion report that will describe the field activities <br /> and document the well destruction methods and procedures. The report will be submitted to <br /> the SJEHD for their files. <br /> SCHEDULE <br /> It is anticipated that the well destruction outlined in this work plan can be completed within <br /> approximately 3 weeks of receiving a permit from the SJEHD. <br /> If you have any questions, please do not hesitate to call. <br /> Sincerely yours, <br /> Langan Treadwell Rollo <br /> Tyler Houghton Jeffrey F.
