Webber Lands Team Lead Western Area Power Administration P.O. Box 281213 Lakewood, CO 80228-8213 Re: Bowie No. 2 Mine (Permit No. C-1996-083) Technical Revision Application No. 66 (TR-66) Terror Creek Vent Shaft Dear Mr. Webber: Harris D. Sherman Executive Director Ronald W. Cattany Division Director Natural Resource Trustee The Division of Reclamation, Mining and Safety hereby issues notice, in accordance with Title 34, Article 33, Section 116, Paragraph 4, of the Colorado Revised Statutes, that on December 22, 2009, an application to revise coal mining operations at the Bowie No. 2 Mine was considered complete for the purposes of filing. The revision was submitted by Bowie Resources, LLC (BRL). All review and comment periods as provided in the Act and the Regulations initiate from this date of filing. In Technical Revision No. 66 (TR-66), BRL is proposing to construct a ventilation shaft for the Bowie No. 2 underground coal mine at a previously disturbed location just west of Terror Creek and just east of the Terror Creek road. The Curecanti-Rifle 230 kilovolt transmission line is located about 200 feet to the west of the proposed site. Attached is a portion of the map that was supplied in BRL's TR-66 submittal that shows the proposed site. The surface is managed by the Bureau of Land Management and leased to BRL under Federal Coal Lease COC-61209. The location of the vent shaft is the same as the location of the geotechnical drill hole that is being proposed in Technical Revision No. 65 (TR-65) and which WAPA was notified of in a letter dated December 11, 2009. The Division has forwarded WAPA's letter, dated December 22, 2009, to BRL as part of the review process for TR-65. The ventilation shaft proposed in TR-66 will be about 690 feet deep and have a finished diameter of 18.5 feet. The shaft will be bored from the bottom up so that the cuttings will remain underground. In order to minimize water infiltration, the shaft perimeter will be grouted before boring begins. In addition, the shaft lining will be grouted with shotcrete. An escape hoist and a nitrogen generation system, powered from within the mine, will be installed at the shaft site. No ventilation fan is planned at this time. The shaft and surface disturbances will be bonded for reclamation. The site is located in the SWASEA of Section 5, Township 13 South, Range 91 West. BRL is proposing to access the site from Steven's Gulch Road, then south on Terror Creek Road. The proposed site is less than 100 feet horizontally from the Terror Creek Road outside right-of-way so a public hearing can be requested to determine if the proposed project will protect the interests of the public and affected landowners.
