Re: Foidel Creek Mine, Permit No. C1982 -056, TR70, Adequacy
Dear Mr. Nettleton:
The Division received Twentymile Coal Company's (TCC's) application for a technical revision (TR70)
on November 20, 2009. The application was determined to be complete on November 30, 2009. No
concerns have been received from other agencies regarding this proposed revision. The SHPO provided a
letter to the Division on December 16, 2009, concurring that no historic properties are expected to be
affected by the activities proposed with TR70. This letter was forwarded to you on December 16, 2009.
The Division has reviewed the proposed revision and has the following concerns:
1. Please include the sediment ponds located at the 18 -Left ventilation site in Section 23 on Map 24.
2. Appendix A, revised page TR09 -70, does not include costs for reclamation of the entire proposed
disturbance. Although TCC proposes to backfill and grade the trench incrementally as the pipeline
installation progresses, TCC must include costs for reclamation of the entire length of the
disturbance. See estimate for TR69 pipeline installation. Please include costs for backfilling and
grading, and topsoil replacement for the entire proposed 75.2 acre disturbance.
3. References to Stream Buffer Zones of 50 feet are incorrect. Rule 4.05.18 defines stream buffer
zones as 100 feet, or greater, of a perennial, intermittent, or ephemeral steam. Fish Creek is a
perennial stream. Revised pages 4.05- 45.18, and 2.05 -50.7 indicate that sediment control
materials will be used at any location where the pipeline corridor is within 50 feet of Fish Creek.
Please bring this distance in compliance with Rule 4.05.18 and employ sediment control measures
within 100 feet of Fish Creek.
4.. TCC previously provided the Division with a copy of the Special Use Permit issued by Routt
County, PP2009 -008, for construction of surface facilities adjacent to Routt County Road No. 27,
and mining beneath Routt County Roads No. 27 and 33. Please provide evidence to the Division
that installation of a waterline beneath Routt County Road No. 27 is consistent with the Routt
County Special Use Permit, or provided evidence that Routt County has approved this activity
beneath the public roadway.
