The Workplan proposes <br /> destruction of the existing twenty two monitoring wells (MW-1 through MW-22), seven soil <br /> vapor wells (VW-1 through VW-7), six ozone sparge wells (OW-1 R through OW-6), and one <br /> groundwater extraction well (EW-1) under San Joaquin County Environmental Health <br /> Department (SJCEHD) well destruction permits. Five of the monitoring wells will be over- <br /> drilled and the borings grouted up; the remaining wells will be pressure grouted. All well <br /> grouting will be inspected by SJCEHD, and the wells destruction will be done in accordance <br /> with the San Joaquin County Standards for Well Construction and Destruction. All associated <br /> underground piping, wiring, and remediation equipment will be removed, soil will be used to <br /> backfill the excavation trenches, and the surface repaired with either soil, asphalt or concrete <br /> as appropriate, to restore both onsite and offsite well locations to pre-existing conditions. <br /> The Workplan is approved as submitted. Please provide a letter report within thirty days of <br /> completion of fieldwork. Include documentation of disposal at a proper disposal facility of any <br /> investigative derived waste (contaminated soil cuttings) generated during the work. Also, <br /> provide SJCEHD and myself at least three working days notice, prior to start of fieldwork. <br /> If you have any questions, you may contact me at (916) 464-4615 or by e-mail at the following <br /> address: jbarton@waterboards.ca.gov. <br /> GAMES L.L.
