ARCO Service Siation No. 2130 Page 3 of 3 <br /> 7906 North EI Dorado Street August 23, 2013 <br /> Stockton, California 95210 <br /> EHD records indicate the presence of 'nested ' wells installed using ten-inch augers. The <br /> EHD has found destruction results of nested wells are best obtained when augers larger in <br /> diameter than the original augers are used and centered on the deepest casing (which is <br /> off-center in the original borehole). The augers need to be sized sufficiently to reach out <br /> and remove all well casings, screens, filter packs, and grout sealant installed during <br /> construction . <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 Boring <br /> Permit Application form along with the encroachment permit, Master File Record form and <br /> appropriate fees for each parcel. The permit fee for the destruction of each well is $125, along <br /> with a $375 Inspection Activity fee per parcel. A review of the site records indicate that 20 <br /> monitoring wells, 11 vapor wells, 3 nested air sparge wells and 3 air sparge wells currently are <br /> Installed . A fee of $5, 375 . 00 (37 x $ 125 $375 x 2) will be required for the well destruction <br /> permits. (Please note that to determine the fees for nested wells, each nested well is considered <br /> as one well for permitting and fee purposes. ) <br /> If you have any questions or concerns regarding this letter, please contact Vicki McCartney at <br /> (209) 468-9852, or by email at vmccartney@sjcehd . com . <br /> Sincerely, <br /> Victoria L.
