Peabody Sage Creek Mine (C-2009-087) <br />MT- 2 <br />American peregrine falcon, ferruginous hawk, greater sage grouse, white-faced ibis, and northern <br />pocket gopher. Further habitat details are listed in Table 2.04.11-T6. <br />No federal threatened or endangered species were documented during the 2008 baseline surveys. <br />The USFWS has federally listed the following species as occurring within Routt County: the Canadian <br />lynx, the Colorado squawfish, razorback sucker, bonytail chub, and humpback chub. There is <br />federally 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 <br />face -up area, construction of surface facilities, and the development of mains, submains, and four <br />sections of entries. Much of the portal face -up area and support structures were constructed in or on <br />backfilled spoil reclaimed under the Seneca II permit. Topsoil has been salvaged and stockpiled <br />onsite. Surface facilities include a variety of buildings, roads, and other structures for supporting an <br />underground mine operation. Surface drainage passes through ditches and sediment control ponds <br />before discharging to Little Grassy and Grassy Creeks. Mine water is pumped from sumps in the <br />portal area and discharged to pond 002. This water would be used as dust control during times of <br />operation. <br />Once the mine restarts operations, continuous miners will develop the workings, and conveyor belts <br />will transport coal and development waste rock to the surface. From the portal area, conveyors on <br />the surface will transport the coal and waste rock to a handling/stockpile area where the material will <br />be loaded into haul trucks. Coal will be transported to either off-site customers or to the Foidel Creek <br />Mine (C1982056) for beneficiation. Surface runoff from all disturbed areas will be channeled to <br />sediment control ponds, with the exception of the runoff from the small warehouse/shop area where <br />alternative sediment control measures will be employed. Under approved Technical Revision TR09, <br />the hydrologic monitoring schedule has been reduced to provide the basic ongoing information <br />required by the DRMS and WQCD. Once the mine comes out of temporary cessation, which is <br />required for both mining and reclamation, the previous operational level monitoring would resume. <br />Both monitoring schedules for active status and temporary cessation status are located in Table <br />2.04.7-T9. <br />Upon completion of underground mining at PSCM, the following reclamation tasks will be performed <br />on surface disturbances: portals will be sealed, structures will be demolished and transported for <br />disposal off-site, the surface will be regraded to approximate original contour, drainage will be re- <br />established, topsoil from the stockpile will be replaced on disturbed areas to a minimum depth of 12 <br />Page 8 of 12 <br />
