The EHD has the following comments regarding the above referenced plan. <br />1. The plan lacks a drawing showing a typical LFG well/probes <br />2. The plan lacks a discussion and map surrounding land uses (residences and CYA). <br />3. The plan did not include any recent landfill gas monitoring results. <br />4. There are three wells that exceed the 1000 foot spacing that is required by Title 27 California Code <br />of Regulation (CCR), Section 20925. These wells are referred to as marginal (regarding spacing). <br />The plan asks for an exemption for the spacing on those wells, but he pian make little or no effort in <br />explaining why the exemption should be allowed. There is a residence directly across from GP -1 and <br />near GP- 25. Please include in your discussion the location of this residence. Title 27 CCR states <br />" (1) The lateral spacing benveen adjacent monitoring wells shall not exceed 1, 000 feet unless <br />the operator demonstrates to the satisfaction of the EA and CMIA based on the factors <br />specified in §20923(a)(2), that there is no potential for adverse impacts on the public health and <br />safehl and the environ►nent ji-om such wider spacing" <br />If you have any questions regarding this matter you can contact the at (209) 468-0332 <br />Sincerely, <br />Robert McClellon <br />Program Coordinator REHS <br />Cc: Loelilin Caffey, Allied Waste Services <br />Gino Yekta, CIWMB MSIOA-18 <br />Christine Karl, CIWMB MS I OA -15 <br />Tadese Gebre-Hawariat MSI OA -17 <br />
