<br />• <br />Introduction <br />TAB 1 <br />Yoast Mule Permitting History <br />Seneca Coal Company (SCC) received State of Colorado approval to mine coal at the Seneca I Mine <br />in 1965, at the Seneca II Mine in 1981, at the Seneca II-W Mine in 1985, and at the Yoast Mine in <br />1995. All of the SCC operations are located in Routt County and are situated east and/or south of <br />the town of Hayden, Colorado. <br />The Yoast Mine is located approximately 4 miles southwest of the Seneca II Mine, 3.5 miles east of <br />the Seneca II-W Mine, and 7.3 miles southeast of the town of Hayden (see Figure 1-1, General <br />Location). Similar to the Seneca II and II-W mines, the coal produced at the Yoast Mine is hauled <br />over private and county roadways by a private hauler to the Hayden Station Power Plant. The <br />haulage distance is approximately 8 miles one way. <br />Permitting History <br />- SCC submitted an application for a new permit to the Division on November 16, 1994 and received <br />the proposed decision to approve on July 5, 1995 and was issued Permit No. C-94082. As shown in <br />the original application, SCC has had contractors inventory and study all the environmental <br />disciplines (i.e., soils, geology, vegetation, wildlife, hydrology, and archaeology) at the Yoast Mine. <br />Additionally, coal exploration at Yoast began in 1963 and continued during four major periods - <br />• 1963-65, 1980, 1988, and 1990-92. The information gained from these studies aided in the <br />development of both an economical and environmentally acceptable mining and reclamation plan. <br />Following is a listing of the technical revisions (TR), permit revisions (PR), and permit renewals (RN) <br />submitted over the history of the Yoast Mine. <br />a Technical Revision (TR-0~.) was submitted on October 8, 1995 and updated the hydrolagic <br />monitoring plan. The proposed decision to approve was issued on November 3, 1995. <br />® 'Technical Revision QTR-02,~ was submitted on December 18, 1995 and addressed the cover <br />standard for concentrated shrub stands.
