(AGE). The Workplan scope of work was <br />also reviewed for permitting and was approved by San Joaquin County Environmental <br />Health Department (SJCEHD) in an email to AGE and Regional Board staff on <br />29 January 2013. <br />The Workplan proposed destruction of forty eight (48) monitoring wells, thirty four <br />(34) soil vapor extraction remediation wells, fourteen (14) air sparge wells and one <br />(1) groundwater extraction well. Pressure grouting will be used to destroy MW-4, <br />MW-10 through MW-14, MW-21, and MW-29. The remaining wells are located in areas <br />of known contamination, and the SJCEHD required those wells to be destroyed by over- <br />drilling the casings to one foot deeper than maximum depth and grouting to surface with <br />neat cement. All surface remediation piping will be removed and underground piping <br />will be capped with grout. The remediation equipment will be salvaged or recycled. A <br />well destruction report will be submitted upon completion of fieldwork. <br />The Workplan is approved. Please submit the well destruction report by 10 May 2013 <br />or provide a rational for an extension with a schedule if unable to meet the 90-day <br />deadline by 25 February 2013. Provide SJCEHD and myself at least three working <br />days notice prior to commencement of fieldwork.
