II. Description of Operation Areas.
The Eastside Mine is located in West Central Colorado in Garfield
County. The main surface facilities area is located approximately
3.5 miles north of Silt, Colorado in the NE}`, Section 24, TSS, R92W
of the 6th Prime Meridan. The area is accessible from Interstate
70, then north of Silt via Garfield County Road 237. The Southern
Pacific railline follows the Colorado River and Interstate 70 from
Silt, Colorado to Rifle, Colorado.
The mining operation is located on the Grand Hogback. The general
topography in the vicinity of Eastside Mine ranges from 7800 feet
down to 6300 feet. The slopes range between 30$ to 50$. The main
feature in the area is Harvey Gap. This is an erosional feature
which cuts completely through the Grand Hogback. Smaller drainages
occur on both sides of Harvey Gap but do not cut completely through
the Grand Hogback. The entire area is extremely steep with some of
the resistant sandstones forming dip slopes over the area. The
Grand Hogback trends in an east-west direction with the major
drainages trending north-south.
The previously disturbed surface areas at the mining site are in a
transitional zone between the alluvial fill and the steep slopes
forming the Grand Hogback. Slopes within the mining site range
between ten percent (10$) to fifty percent (50$). The topography
of the area lends itself to very abrupt changes in slope.
The pre-mining land uses of the permit area are mining and
undeveloped land. Active mining, on an intermittent basis, has
occurred in the Harvey Gap area from the late 1800's until 1979.
The Grass Valley Reservoir located to the north of the permit area
is classified as a developed water resource. The Grass Valley
Reservoir is up drainage from the Eastside Mine.
There are no residences or commercial developments within a mile of
the mine. Cropland is located approximately 1.5 miles to the north
and to the south of the mine. Wildlife is generally found
throughout the permit area and adjacent areas. Mining has had no
significant impact on the wildlife except the loss of grazing from
the previously disturbed areas.
The area disturbed by the Eastside Mine surface operations and
facilities has little capability of being productive except as a
mining facility or wildlife grazing. The steep terrain and the
limited rocky nature of the soils in the area will not support any
type of ~_ _-----.
There are currently 299 acres permitted at the Eastside Mine. The
operation areas include the Haulage Road and the Surface Facilities
hrea (see Drawing: SWMP.DWG). The Haulage Road and the Surface
