Hickenlooper <br />Governor <br />Mike King <br />Executive Director <br />Loretta E. Pineda <br />Director <br />The Division received Sage Creek Coal Company's (SCC) application for a minor revision (MR-03) <br />on June 3, 2011. The application was determined to be complete on June 10, 2011. The Colorado <br />Division of Reclamation, Mining and Safety has completed its adequacy review of the proposed minor <br />revision. Please respond to the following comments or concerns as necessary: <br />1. The proposed Map 2.05.3 M1B Mine Facilities Map (North End) displays the revised <br />disturbance boundary in the area of Haul Road B. Map MIB also shows that Haulroad B has <br />shifted to the west in the area of the proposed disturbance boundary. This shift in the location <br />of Haul Road B is in conflict with the location delineated on the approved Map M1B in the <br />permit. <br />This Haul Road B location change also creates a conflict with the approved Map 2.05.3 M 1 A <br />Mine Facilities Map (South End), as the change in haul road location does not match up with <br />the haul road B location in Map MIA. The conflict between approved Map MIA and proposed <br />Map M 1 B also affects the disturbance boundary location. Please provide a discussion or a <br />revised map M1B to reflect the correct location of Haul Road B or M1A to reflect the new <br />location of Haul Road B and the new Disturbance Boundary. <br />2. Proposed Map 2.05.3 M 1 B identifies a drainage channel in the middle of Haul Road B. It <br />appears that this channel should be on either the east or west side of the Haul Road. The <br />approved Map 2.05.3 M 1 B delineates this channel on the west side of the Haul Road. Please <br />revise proposed Map 2.05.3 M1B to reflect the correct location of this drainage channel. <br />Please feel free to contact me with any questions at (303) 866-3567 ext 8134. <br />Sincerely, <br />raon?nmental Protection Specialist <br />Office of Office of <br />Mined Land Reclamation Denver • Grand Junction • Durango Active and Inactive Mines
