Three Former Vapor Extraction Wells October 12,2010 <br /> Former Nestle USA,Inc.Facility,Ripon,CA <br /> .r.i. <br /> tlSurveyed location for VE-4,facing southeast. 4Surveyed location for VE-11, facing south. <br /> a New fence (installed May 2010) across former <br /> location of VE-12. The foreground "X" marks the <br /> geodetic survey. The "X" directly under the fence <br /> marks the GPR anomaly. The patched area was <br /> left behind in May 2010 from a fence post which <br /> was moved. <br /> PROPOSED ACTIONS FOR VE-4, VE-11, AND VE-12 <br /> 1) ECM is proposing a 5-foot by 5-foot excavation to a depth of 5 feet bgs in the location of each of <br /> the three former well locations identified during the geodetic survey/GPR search. <br /> 2) If ECM locates any of the missing VE wells during this excavation effort: <br /> a. ECM will stub up the well locations to above ground surface and backfill around the <br /> stubbed-up locations. <br /> b. The locations will be sealed to protect from surface water infiltration and coned to <br /> prevent vehicular damage. <br /> c. ECM will obtain the necessary well destruction permits form SJC-EHD. <br /> d. Prior to commencing decommissioning activities with a California licensed driller, <br /> ECM will contact SJC-EHD to notify the inspector of the work start date. <br /> e. ECM will notify SJC-EHD within 24-hours of the need for a grout inspection. <br /> 3 <br />
