Pineda Director The Division of Reclamation, Mining and Safety (DMG) hereby issues notice, in accordance with Title 34, Article 33, Section 118, Paragraph 3, of the Colorado Revised Statutes, that on June 28, 2010, an application to revise coal mining operations at the Seneca H Mine was considered complete for the purposes of filing. All review and comment periods as provided in the Act and the Regulations initiate from this date of filing. This revision application proposes a reduction in size of the Seneca H permit boundary. The proposed reduction is to accommodate the new Peabody Sage Creek Mine (PSCM) permit area, which will incorporate approximately 3, 011.9 acres of the original Seneca II permit area. The revised Seneca 11 permit area will retain 386.5 acres of the original permit area that includes 271.0 disturbed acres. The revised Seneca 11 mine permit boundary encompasses one isolated watershed and separates runoff from the Seneca H mine and the new PSCM permit area. The watershed discharges to pond 008, which is an approved NPDES discharge point. Proposed changes to the current permit boundary and associated changes to the operations and reclamation plans are set forth in a new volume to the permit application package titled "Permit Revision (PR-02) reduced permit area. The surface coal mining operation is on land located approximately 9 miles Southeast of Hayden, Colorado. The permit area is further described as follows: T5N, R87W; All of Sections 1, 2 and 12; Portions of Sections 3, 11 and 13 T6N, R87W; Portions of Sections 27, 34, 35 and 36 T5N, R86W; Portions of Sections 6 and 7. The above-mentioned tracts of land are shown on USGS 7.5 minute Quadrangle map of Milner & Mount Harris. No additional surface disturbance is proposed as a result of this revision application (the permit area would be reduced by over 3000 acres). The portion of the permit area that would be removed, has recently been permitted by Peabody Sage Creek Coal Company, as a part of the new Peabody Sage Creek Mine. Mining operations have been completed within the proposed reduced permit area, the entire area has been backfilled, Office of Office of Mined Land Reclamation Denver • Grand Junction • Durango Active and Inactive Mines
