the Colorado squawfish, razorback sucker, bonytail chub, and humpback chub. There is federally <br /> designated critical habitat along the Yampa River for these four species of fish. <br /> Description of the Operation and Reclamation <br /> The PSCM has been in temporary cessation since January of 2017. Coal has been mined from the <br /> Wadge seam using underground room and pillar methods. Pillars will not be removed. Depending on <br /> favorable economics, a full-scale long wall mine would be approved in future revisions. <br /> Operations during the first five-year permit term of the PSCM involved construction of the portal face- <br /> up area, construction of surface facilities, and the development of mains, submains, and four sections of <br /> entries. Much of the portal face-up area and support structures were constructed in or on backfilled spoil <br /> reclaimed under the Seneca II permit. Topsoil has been salvaged and stockpiled onsite. Surface <br /> facilities include a variety of buildings, roads, and other structures for supporting an underground mine <br /> operation. Surface drainage passes through ditches and sediment control ponds before discharging to <br /> Little Grassy and Grassy Creeks. Mine water is pumped from sumps in the portal area and discharged to <br /> pond 002. This water would be used as dust control during times of operation. <br /> Once the mine restarts operations, continuous miners will develop the workings, and conveyor belts will <br /> transport coal and development waste rock to the surface. From the portal area, conveyors on the surface <br /> will transport the coal and waste rock to a handling/stockpile area where the material will be loaded into <br /> haul trucks. Coal will be transported to either off-site customers or to the Foidel Creek Mine <br /> (C1982056) for beneficiation. Surface runoff from all disturbed areas will be channeled to sediment <br /> control ponds, with the exception of the runoff from the small warehouse/shop area where alternative <br /> sediment control measures will be employed. Under approved Technical Revision TR09, the hydrologic <br /> monitoring schedule has been reduced to provide the basic ongoing information required by the DRMS <br /> and WQCD. Once the mine comes out of temporary cessation, which is required for both mining and <br /> reclamation, the previous operational level monitoring would resume. Both monitoring schedules for <br /> active status and temporary cessation status are located in Table 2.04.7-T9. <br /> Upon completion of underground mining at PSCM,the following reclamation tasks will be performed on <br /> surface disturbances: portals will be sealed, structures will be demolished and transported for disposal off- <br /> site, the surface will be regraded to approximate original contour, drainage will be re-established, topsoil <br /> from the stockpile will be replaced on disturbed areas to a minimum depth of 12 inches, and seeding and <br /> shrub transplants will be performed for providing erosion control and for supporting the post mining land <br /> uses of rangeland, wildlife habitat, and recreation. <br /> Section II - Revisions to the Permit <br /> The following revisions have been submitted since the last midterm review of the Peabody Sage Creek <br /> Mine permit application package. <br /> CO10 <br /> e <br /> 1313 Sherman Street, Room 215, Denver, CO 80203 P 303.866.3567 I `�' O <br /> �`1876� <br />
