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 <br /> Canadian lynx, the Colorado squawfish, Grey Wolf, razorback sucker, bonytail chub, and humpback <br /> chub. There is federally designated critical habitat along the Yampa River for these four species of <br /> fish. <br /> Description of the Operation and Reclamation Plans <br /> The PSC has been in temporary cessation since January of 2017. Coal has been mined from the <br /> Wadge coal seam using underground room and pillar methods. Pillars will not be removed. <br /> Depending on favorable economics, a full-scale longwall miner would be approved in future <br /> revisions. <br /> Operations during the first five-year permit term of the PSC involved construction of the portal face- <br /> up area, construction of surface facilities, and the development of mains, submains, and four sections <br /> 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 active <br /> operation. <br /> Should the mine restart operations, continuous miners will develop the workings, and conveyor <br /> belts will transport coal and development waste rock to the surface. From the portal area, <br /> conveyors on the surface will transport the coal and waste rock to a handling/stockpile area where <br /> the material will be loaded into haul trucks. Coal will be transported to either off-site customers or <br /> to the Foidel Creek Mine (C1982056) for beneficiation. Surface runoff from all disturbed areas will <br /> be channeled to sediment control ponds, with the exception of the runoff from small <br /> warehouse/shop area where alternative sediment control measures will be employed. Under <br /> approved Technical Revision TR09,the hydrologic monitoring schedule has been reduced to provide <br /> the basic ongoing information required by the DRMS and WQCD. Once the mine comes out of <br /> temporary cessation, which is required for both mining and reclamation, the previous operational <br /> level monitoring would resume. Both monitoring schedules for active status and temporary <br /> cessation status are presented in Table 2.04.7-T9. <br /> Upon completion of underground mining at PSC, the following reclamation tasks will be performed on <br /> surface disturbances: portals will be sealed, structures will be demolished and transported for disposal <br /> off-site, the surface will be regraded to approximate original contour, drainage will be re-established, <br /> topsoil from the stockpile will be replaced on disturbed areas to a minimum depth of 12 inches, and <br /> seeding and shrub transplants will take place providing erosion control and for supporting the post <br /> mining land uses of rangeland, wildlife habitat, and recreation. <br /> Page 10 of 27 <br />
