If these analyses show that the regraded topsoil material is unsuitable as a plant
growth medium, it will be enriched with appropriate fertilizer of a type and at a rate
recommended by the analyzing laboratory.
3. Revegetation Procedures.
a. General Description.
Revegetation of those areas disturbed by mining activities will be accomplished with
species native to the area or with other approved species that will support
post-mining land uses, which include cattle grazing and wildlife habitat.
During the mine life research is being conducted to determine the best procedures
for reclaiming and revegetating the unique terrain and soil conditions found in Coal
Basin.
In Coal Basin revegetation plans must address such varied disturbed areas as mine
portal areas, roads, coal refuse disposal areas, the rock tunnel portal areas and the
preparation plant area. All these areas are located at elevations ranging from 8,000
to 11,500 feet. The terrain is unusually steep and rugged, and the winters are long
and harsh.
Vegetation test plots were established in 1983 on steep spoil slopes at three
separate subalpine locations. The objective of the test plots is to help determine
how best to revegetate the steep slopes of benches and roads. Vegetation cover
and production were measured on August 13 and 14, 1987. The report, prepared
by Intermountain Soils, is contained in App V-E-4.
The normal period for favorable planting of seeds, seedlings or other plant materials
in Coal Basin is in the fall.
