portal at the D/E outcrop [o ramp down co the :B seam reserves ac depth (300 <br />feet below the surface). Access to the reserves from across the river is <br />. also not likely due to the 100-year floodplain and existing rights-of-way. <br />This alternative was considered but not analyzed. <br />In the unlikely situation chat another portal is constructed, <br />approximately 40 acres would be disturbed. An additional environmental <br />analysis (NEPA) must be completed to determine the impacts resulting from <br />the proposed disturbance of a new portal and related surface facilities and <br />structures. This EA does not analyze the impacts of the construction of a <br />new portal. Additional stipulations and mitigation could be reouired upon <br />the completion of the NEPA analysis. Areas stipulated as No Surface <br />Occupancy or designated Unsuitable for Coal mining as listed in Section V <br />of this EA could not be considered for any future proposed surface <br />facilitiesjportal, unless a waiver, exception, or modification were <br />granted. <br />Alternative One - Prooosed Action <br />The proposed action is co offer for competitive lease 2764.67 acres of <br />federal coal, the Box Canyon Tract, containing approximately 37 million <br />tons of recoverable reserves. The coal reserves are in the B and D/E seams <br />of the Mesaverde formation. Leasing the coal would allow for t.-.~ aost <br />efficient development of federally owned coal. <br />The applicant's lease application was amended to include an additional <br />453.67 acres lying along the southern boundary of the application area as <br />wel! as 40 acres lying east of Sylvester Gulch. The additional area was <br />incorporated into taa tract in order to ensure all federal coal for which <br />there were adequate data were included to avoid a potential bypass tract in <br />the future. The applicant's proposed action as amended by the BLY is the <br />Bureau's and USFS's preferred action. <br />Reasonably Foreseeable Development <br />A reasonably foreseeable development (RFD) scenario was developed <br />based on expansion of Mountain Coal Company's present operations. This <br />scenario is used co estimate the surface impacts of the mining of the coal <br />on the Box Canyon tract. The RFD does not suggest specific locations for <br />potential surface facilities beyond indicating a general area of <br />anticipated occurrence. Thus, the RFD does not provide a basis for a <br />site-specific discussion of environmental consequences. <br />Subsurface Develoomenc <br />The coal reserves could be mined Erom the applicant's existing <br />operation, the West Elk Mine. The tract lies to the east of a block of <br />existing federal coal leases held by Mountain Coal Company; the existing <br />leases are operated as the kest Elk (line. Production Erom the West Elk <br />Mine was approximately 3 million tons in 1993, 1.4 million tons in 1992, <br />716,000 tons in 1991 and averaged 560.000 tons in the years 1989 co 1990. <br />Access to the reserves on the proposed tract is limited by previous <br />mining in the D/E seam, mining conditions and lack of B seam outcrop. The <br />best access to the tract is from the Wes[ Elk Yine. The workings of the <br />. mine would be extended to the east. <br />6 <br />
