U.S. DEPARTMENT OF THE INTERIOR
OFFICE OF SURFACE MINING RECLAMATION AND ENFORCEMENT
FINDING OF NO SIGNIFICANT IMPACT
FOR
Colowyo Mine
Federal Lease C-29224
Mining Plan Decision Document
A. Introduction
Colowyo Coal Company submitted a permit application package (PAP)
for a permit revision for the Colowyo Mine to the Colorado Mined
Land Reclamation Division (NERD) under the Colorado State program
(30 CFR Part 906). The PAP proposes extending surface mining
operations into about 497 acres of Federal lease C-29224. The
proposed mining plan would cause about 230 acres of new surface
disturbance in the mining plan area.
Under the Mineral Leasing Act of 1920, the Assistant Secretary,
Land and Minerals Management must approve, approve with
conditions, or disapprove the mining plan modification for
Federal lease C-29224. Pursuant to 30 CFR Part 746, the Office
of Surface Mining Reclamation and Enforcement (OSM) is
recommending approval of this mining plan modification.
B. Statement of Environmental Significance of the Proposed Action
The undersigned person has determined that the approval of the
mining plan modification would not have a significant impact on
the quality of the human environment under section 102(2)(C) of
the National Environmental Policy Act of 1969 (NEPA), 42 U.S.C.
§§ 4332(2)(C), and therefore, an environmental impact statement
is not required.
This finding of no significant impact is based on the attached
environmental assessment prepared by OSM which identifies and
f discusses the environmental impacts of the proposed action.
