uJScc/F/LE <br />• <br />• <br /> <br />West Elk Coal Company, Inc. <br />Post Olfice Box 597 <br />So mersel. Colorado 81434 <br />Telephone 303 929 5015 <br />May 30, 1986 <br />Susan Mowry <br />Reclamation Specialist <br />Colorado Mined Land Reclamation Division <br />1313 Sherman Street <br />Denver, CO 80203 <br />Dear Susan: <br /> <br />West Elk Coal Company requests approval of a minor <br />revision to install a dewatering pipe in sediment <br />pond MB-5, Bear No. 1 portal area, to dewater the <br />pond to the North Fork of the Gunnison River. The <br />minor revision will be to CMLRD Permit C-007-80, Mt. <br />Gunnison No. 1 Mine. <br />The dewatering pipe will consist of a 75 foot long <br />steel pipe placed on a minimum grade of 0.58 and a <br />maximum grade of 1.08 and equipped with a manually <br />operated control valve. Revised attachments D and G <br />are enclosed and show the location and elevation of <br />the proposed dewatering pipe. <br />In addition to installing the dewatering pipe, the <br />emergency spillway will be relocated as shown on <br />revised Attachment D. The purpose of this relocation <br />is to prevent having to apply for an additional NPDES <br />discharge point. The existing spillway will be elim- <br />inated. A modification will be made to the NPDES <br />discharge point 009, Permit No. CO-0038776 to <br />relocate the sampling point. Per phone discussion <br />with Jon C. Kubic of the Colorado Department of <br />Health, it may take in excess of two months to <br />approve a modification of outfall 009. They will not <br />be able to determine exact timing until they have <br />looked at the request for modification. I will <br />forward the request for modification to the Colorado <br />Department of Health as soon as possible. <br />c~,1~0-6`tG3 <br />
