Submit a complete list of record owners of fee title and their trailing addresses to the <br /> EHD. A form has been enclosed for this purpose. Please submit the information at your <br /> earliest convenience. <br /> During the sixty-day public participation period, it is necessary to plan and prepare to execute <br /> the destruction of all wells installed as part of your site investigation and remedial action so that <br /> once responses received during the sixty-day public participation period have been properly <br /> addressed, well destructions can commence. <br /> Please submit a scope of work proposal that details the conditions and construction of the wells <br /> and the methods and materials to be used to destroy them. To be issued a well destruction <br /> permit, the proposal must address the concerns 'of the EHD and the San Joaquin County Well <br /> Standards requirements, such as: <br /> • Wells that have laboratory data from the last sampling event that demonstrate the <br /> presence of any contaminants of concern are to be destroyed by removing all the <br /> contents of the well (conductor casing; well casing, screen, filter pack, grout sealant); the <br /> cleared borehole is then to be sealed with neat cement from the bottom upward to the <br /> depth of three to five feet below grade. <br /> O All wells with unknown construction and/or located in an area of known or suspected <br /> contamination are to be destroyed by removing all the contents of the well (conductor <br /> casing, well casing, screen, filter pack, grout sealant); the cleared borehole is then to be <br /> sealed with neat cement from the bottom upward to the depth of three to five feet below <br /> grade. <br /> • Wells that have laboratory data from the last sampling event that report non-detectable <br /> concentrations of contaminants of concern and with acceptable laboratory detection <br /> limits, and are not in areas of known or suspected soil contamination, may be destroyed <br /> by pressure grouting form the bottom upward, while leaving the well casing in place. <br /> The top three feet or more of the well shall be drilled out with an auger that is at least <br /> one foot larger in diameter than the auger originally utilized to install the well, and the <br /> soil around the cut-off casing removed to the depth of an additional six inches below the <br /> new 'top' of the cut-off casing- The grout sealant shall spill out of the top of the well <br /> casing to form a mushroom cap seal with at least twelve inches of neat cement grout <br /> poured six inches above and six inches below the top of the cut-off casing. <br /> All groundwater displaced to the surface during grout installation shall be pumped out of <br /> the excavation to allow for EHD inspection and verification that the, well has been <br /> properly destroyed. Contaminated groundwater pumped out of the excavation shall be <br /> containerized for proper disposal. <br /> After the EHD has approved the well destruction scope of work proposal and the public <br /> participation comments have been properly addressed, you may submit an EHD Well and <br /> Boring Permit Application form along with a Master File Record form and appropriate fees for <br /> each parcel. The permit fee for the destruction of each well is $125, along with a $375 <br /> Inspection Activity fee. A review of the site records indicate that eleven monitoring wells <br /> currently are installed. A fee of $1,750.00 (11 x $125 + $375) will be required for the well <br /> destruction permits. <br />
