SJCEHD is the regulatory agency that <br /> will be handling the well destruction permit(s) and inspections. <br /> have received a copy of your October 6, 2011 , Well Destruction Work Plan and <br /> noticed some concerns that you need to be aware of. Although the SJCEHD is <br /> not the lead agency, well installation and destruction falls under our jurisdiction. <br /> I've attached a copy of an email I sent in response to Melissa Straten's May 3, <br /> 2011 email and voice message to me regarding pressure grout well destructions. <br /> The only change in the information I included in the email response is a change <br /> in our fees. Destruction permits are now $375 per application-per parcel and <br /> $125 per well, pressure grout or over-bore. Based on 87 wells, our permit fee is <br /> $11 ,250. <br /> 1 was unable to discern if the 56 wells proposed in the work plan for pressure <br /> grouting qualify. I will need the most recent laboratory data from each well to <br /> determine this. The latest gw, soil, or vapor data will support conclusions that the <br /> well is "not in an area of known or suspected pollution/contamination..."as our <br /> Ordinance mandates. Lack of data, unknown well construction, obstruction to <br /> total depth of construction, or the presence of detectable concentrations in the <br /> newest/latest sample data disqualifies the well from pressure grouting. Over <br /> bore or wire line explosives are the only remaining options. <br /> Please provide lab data to support `contamination' conclusions or be prepared to <br /> drill out/wire-line the well(s). <br /> The Ordinance section numbers referenced in the email to Melissa Straten are <br /> available for your review at the following webpage. Monitoring well destruction <br /> procedures are included in the last chapter, #13. <br /> 10/14/2011 <br />
