(Claim 12886 and Case 2251 <br /> Jatin, <br /> In response to your email concerning the installation of additional extraction wells as opposed to using existing <br /> wells, the existing wells have two-inch-diameter casings and are screened from five to approximately twenty-five <br /> feet below surface grade(bsg) (below the impacted zone at approximately ten to fifteen feet bsg). The new <br /> extraction wells have a six-inch-diameter-casing and are screened to approximately fourteen feet bsg. Since <br /> the original wells are screened much deeper, the original wells would require removing groundwater below the <br /> impacted area. <br /> Vicki McCartney, Senior REHS <br /> San Joaquin County <br /> Environmental Health Department <br /> 1868 East Hazelton Avenue <br /> Stockton, California 95205 <br /> Phone: (209)468-9852 <br /> Email: vmccartnev(asicehd.com <br /> i9 <br /> From: Khandwala,Jatin@Waterboards [mailto:Jatin.Khandwala@waterboards.ca.gov] <br /> Sent: Tuesday, September 09, 2014 12:35 PM <br /> To: Vicki McCartney [EH] <br /> Subject: RE: Frontier Transportation -425 Larch,Tracy. (Claim 12886 and Case 2251 <br /> Sure, no problem. I am also going to ask 5 year grp to see if it qualifies for Low Risk Closure. Since it is <br /> transportation facility and there are no supply wells, it may qualify for low risk case. <br /> In addition,just curious about new extraction well install. I have not looked at the map yet. But would <br /> have been feasible to use existing MWs instead of installing a new extraction wells? That way they could <br /> have saved some funds. They only have $200K left(assuming LOW RISK closure fails). <br /> Jatin <br /> NOTE: For general status questions about reimbursement requests, budgets or budget change <br /> requests, appeals or general program information, please refer to the Fund's website at: <br /> www waterboards ca gov/water issues/programs/ustcf.
