or during baseflow periods (October through March). BRL will screen the intake pump in the East Fork of Terror Creek to protect Greenback Cutthroat Trout fry. • BRL will conduct fish, sediment and macroinvertebrate sampling every two years and twice following mining activities. Description of the Operation and Reclamation Plans Detailed information regarding the operation and reclamation plans for the Bowie No. 2 Mine is presented in Section 2.05 of the Bowie No. 2 Mine permit application document. Section 2.05 of the permit also contains numerous references to maps and other information related to the Bowie No. 2 Mine operations and reclamation plans, which are contained in various sections of the permit application document volumes. The following summary is derived from the information presented in the Bowie No. 2 Mine permit application document. Coal from the Bowie No. 2 Mine was originally extracted using the room and pillar mining method. Retreat mining of some of these sections has also occurred. Approval of Permit Revision No. 3 allowed the mining method to change to longwall mining. The D -2 coal seam was accessed from three (3) entries which were constructed at an elevation of 6880 feet above sea level. This is the elevation where the D -2 coal seam generally outcrops, within the Bowie No. 2 permit area, and this elevation is approximately 800 feet above the old State Highway 133. The main entries were driven down -dip to the north, with the sub -mains being driven east and west from the mains. The B -2 coal seam is currently being accessed through three (3) mine entries. The B -2 coal seam portals are located below and just to the east of the D -2 coal seam portals, at an approximate elevation of 6630 feet. The development mining and longwall mining of the B -2 coal seam were approved in Permit Revision No. 8. The B -2 coal seam mine plan was amended in Permit Revision No. 9. Mining of the B -2 seam was subsequently expanded with Permit Revisions 10, 11, 12, and 13. PR -14 will further expand B -2 seam mining to the north of existing operations. Currently, total annual coal production has been capped at 6 million tons per year. Production data from the Colorado Mine Safety and Training Program shows and average production rate of 3.5 million tons over the 2001 -2013 period. The mine facilities have been constructed near the old Bowie town site. Facilities include: • haul and access roads • conveyor belt system • vent shafts • truck loadout • unit train loadout • coal stockpiles • refuse piles • drainage and sediment control facilities, and • portable methane pumps used at gob vent boreholes. Coal travels by covered conveyor line from the B -2 coal seam portal bench to the D -2 coal seam Page 21 of 46
