<br />Summary • <br />History of the Review Process, Description of Environment <br />and <br />Description of the Operation and Reclamation Plan <br />History of the Review Process <br />The Red Canyon Mine application was submitted to the Division on February 17, <br />1981 and deemed complete on February 27, 1981. A joint preliminary adequacy <br />letter conveying concerns identified by the Office of Surface Mining and the <br />Division was sent to Grand Mesa on May 8, 1981. Resolution of the <br />deficiencies noted during the review was required in order to make <br />determinations of compliance. The preliminary adequacy comments were <br />discussed and clarified at a meeting on June 10, 1981, between MLRD and OSM <br />staff members and Grand Mesa Coal Company representatives. Grand Mesa's <br />responses to the preliminary adequacy letter were received on August 31, 1981. <br />A number of significant hydrologic and alluvial valley floor (AVF) concerns <br />were discussed by the Division in a review letter of January 13, 1982. In <br />order to address the Division's concerns, Grand Mesa implemented field <br />investigations and analyses during the spring and summer of 1982. <br />Determinations and conclusions of the hydrologic study, entitled "Hydrology <br />and Alluvial Valley Floor Report, Red Canyon Mines" were submitted to the <br />Division on September 9, 1982, as Volume 8 of the permit application. <br />A draft findings document identifying remaining adequacy issues was prepared <br />on March 14, 1983. A mining and reclamation permit was issued on July 13, <br />1983. The applicant's final responses were received by the Division from <br />November, 1983, through March, 1984. <br />Grand Mesa Coal Company, a Colorado General Partnership involving Tremont Coal <br />Corporation, Eagle Mining Inc. and Pine Brook Mining Company, submitted a <br />permit renewal application on January 13, 1988 for the Red Canyon No. 1 and <br />Red Canyon No. 2 Mines. The managing agent for the partnership is Western <br />Associated Energy Corporation. <br />The Division sent out adequacy letters on February 18, 1988, March 23, 1988, <br />June 10, 1988, and June 24, 1988. These letters requested clarification or <br />additional information on matters related to the geochemistry of materials <br />found on site, the post-mining topography and its associated drainage, the <br />value of the bond, and consent documentation for undermining. These issues <br />were resolved in correspondence received on February 29, 1988, May 13, 1988 <br />and July 11, 1988, and contained in Technical Revisions 3 and 4. <br />-3- <br />
