Re: Sanborn Creek Mine (Permit No. C-S1-022)
Technical Revision Application No. 33 (TR-33)
Temporary Pond E As-Built and Reclamation Bond Estimate
Dear Sir or Madam:
The Division of Minerals and Geology hereby issues notice, in accordance with Title 34, Article 33, Section 116,
Paragraph 4, of the Colorado Revised Statutes, that on May 21, 1999, an application to revise coal mining operations
at the Sanbom Creek Mine was considered complete for the purposes of filing. The revision was submitted by
Oxbow Mining, Inc.. All review and comment periods as provided in the Act and the Regulations initiate from [his
date of filing.
This technical revision would approve the as-built certification and reclamation bond liability estimate for temporary
Pond E, which had been constructed as an emergency mine dewatering pond located adjacent to the North Fork of
the Gunnison River.
The underground coal mining operation is on land located immediately North of Somerset. The permit area is further
described as follows:
Portions of Section 31, Township 12 South, Range 90 West;
Portions of Sections 34, 35 and 36, Township 12 South, Range 91 West;
Portions of Sections I, 2, 3, 4, 5, all of 6 and 7, Portions North of the North Fork of the Gunnison River in Sections
8, 9, 10, portions of Sections 11, 12, and 17, Township 13 South, Range 90 West,
Portions of Sections I-3, I 1-13, Township 13 South, Range 91 West of the 6th P.tvi.
The above-mentioned tracts of land are shown on USGS 7.5 minute Quadrangle map of Somerset.
Because the above referenced technical revision application would incorporate additional lands into the permit area
or might otherwise alter previously approved permit conditions or mitigation measures, we are requesting your
agency's evaluation of the potential for impacts to threatened or endangered species of plants or animals, or wildlife
species otherwise protected by federal law.
In order for us to approve this revision, we are required to make a finding that "the activities would not affect the
continued existence of endangered or threatened species or result in [he destruction or adverse modification of their
critical habitats as determined under [he Endangered Species Act of 1973...." We request your review and
