M 2004-078 <br />Dear Ms. Cmshy: <br />Danna Ortiz and Mark Reiner, both employees of Civil Resources, LLC, supplied us with a copy <br />of portions of the Permit Application for-the Lupton Lakes Resource pit. Items included were <br />----- - --- - <br />- _ _ _ - - -- xhe.Reclamation-Plan,-the-Mrning~lan, and various mapsthatwere includ ~ the Pertnrt- - - - <br />Application. They also provided additional information concerning geology, geotechnical <br />conditions, dnil)ing logs, easements, material properties, and slope stability calculations justifying <br />the set back distances they are proposing for the mining excavation. <br />As stated in the objection letter, our primary concern at that time was predicated oa a lack of <br />information concerning the proposed mining operation. Ms. Ortiz and Mr. Reiner have been most <br />helpful in suppling information concerning the operation, <br />Conversations with DMG and Civil Resources have indicated that changes to the original <br />Application are being considered or have been made. However, to mitigate the possibility of <br />misunder'standings, the following comments have been predicated on the documems that we <br />currently have. When revised documents are provided, the concerns can be readdressed <br />considering the changed conditions. <br />AREA OF CONCERN: <br />EXISTING EASEMEN)'S <br />• Information supplied conceming easements states that an existing oil well on the Adams <br />property has a 50 foot easeme-rt along U5 Hwy. 8i. The maps locate the well and show a <br />gas line rurmir-g westerly from the well to the property line. The map doesn't indicate <br />where the easement is located, Does the }ine turn north or south on an easemem inside <br />the property line, or does it cross into the CDOT ROW7 Wili the proposed mining <br />operation cause the pipeline to be relocated? ff so, and if it crosses into CDOT ROW, <br />how will the relocation a$ect CDOT. If the easement is in the affected area, and if it is <br />left in place, will that increase the buffer between the excavation and the property line? <br />EXHIDTT D-MI1~11NG PLAN <br />• Paragraph (a) states that dewmtering trenches will be excavated down to ground water. <br />Vest hole logs indicate that ground water was located at 15 feet to 25 feeht down into the <br />gravel. It is assumed that the trenches will be dug oa the perimeter of the excavated area, <br />and if so will the back slopes be at the 0.5 to 1 shown in paragraph (b), or will the <br />
