portal at the D/E outcrop to ramp down to the :B seam reserves ac depth (300
feet below the surface). Access co the reserves from across the river is
• also not likely due co the 100-year floodplain and existing rights-of-way.
This alternative was considered but not analyzed.
In the unlikely situation that another poztal is constzucted,
approximately 40 acres would be disturbed. An additional environmental
analysis (NEPA) must be completed to determine the impacts resulting from
the proposed disturbance of a new portal and related surface facilities and
structures. This EA does not analyze the impacts of the construction of a
new portal. Additional stipulations and mitigation could be reouired upon
the completion of Che NEPA analysis. Areas stipulated as No Surface
Occupancy or designated Unsuitable for Coal mining as listed in Section V
of this EA could not be considered for any future proposed surface
facilities/portal, unless a waiver, exception, or modification were
granted.
Alternative One - Provosed Action
The proposed action is to offer for competitive lease 2769.67 acres of
federal coal, the Box Canyon Tract, containing approximately 37 million
tons of recoverable reserves. The coal reserves are in the B and D/E seams
of the Mesaverde formation. Leasing the coal would allow for t:.~ most
efficient development of federally owned coal.
1"he applicant's lease application was amended to include an additional
453,67 acres lying along the southern boundary of the application area as
. wel' as 40 acres lying east of Sylvester Culch. The additional area was
incorporated into tha tract in order co ensure all federal coal for which
there were adequate data were included to avoid a potential bypass tract in
the future. The applicant's proposed action as amended by the BLK is the
Bureau's and USFS's preferred action.
Reasonably Foreseeable Developmenr
A reasonably foreseeable development (RFD) scenario was developed
based on expansion of Mountain Coal Company's present operations. This
scenario is used to estimate the surface impacts of the mining of the coal
on the Box Canyon tract. The RFD does~not suggest specific locations for
potential surface facilities beyond indicating a general area of
anticipated occurrence. Thus, the RFD does not provide a basis for a
site-specific discussion of environmental consequences.
Subsurface Development
The coal reserves could be mined from the applicant's existing
operation, the West ELk Hine. The tract lies to the east of a block of
existing federal coal leases held by Mountain Coal Company; the existing
leases are operated as the West Elk t1ine. Production from the Wesc Elk
Hine was approximately 3 million tons in 1993, 1.4 million cons in 1992,
716,000 tons in 1991 and averaged 560.000 tons in the years 1989 to 1990.
Access to the reserves on the proposed tract is limited by previous
mining in the D/E seam, mining conditions and lack of B seam outcrop. The
best access to the tract is `rom the West Elk Hine. The workings of the
• mine would be extended to the east,
