Technical Revision No. 01 (TR-01), Adequacy Review
Dear Mr. Cowman,
The Division received Sage Creek Coal Company's (SCC) application for a technical revision (TR-01)
on December 13, 2010. The application was determined to be complete on December 22, 2010. No
concerns have been received from other agencies regarding this proposed technical revision. The
Colorado Division of Reclamation, Mining and Safety has completed its adequacy review of the
proposed technical revision. Please respond to the following comments or concerns as necessary:
1. The first sentence of the initial paragraph on page 2.05-5 of the revised text discusses the
movement of coal from a small on-site storage stockpile to nearby customers. Map 2.05.3
MIA identifies two coal handling facilities areas labeled 17 and page 2.05-17 discusses two
stockpile locations. Please delineate which area, or both, that will be used for on-site
storage of coal.
2. The first sentence of the fifth paragraph on page 2.05-5 of the revised text states that, "New
surface facilities in Little Grassy Creek watershed will include the mine portal face-up area,
temporary topsoil and overburden stockpiles, a coal stock pile, and coal handling facilities."
Map 2.05.3 identifies two coal handling facilities, but no indication is given for the location of
the coal stockpile or if there will be coal stored at both coal handling facilities locations.
Please discuss and identify on Map 2.05.3 MIA the location of the coal stockpile(s).
3. The fourth paragraph on page 2.05-13, under the heading Material and Equipment Storage
Yards, states that, "Two material and equipment storage yards will be located near the portal
area," and the storage yards will cover an area of approximately 11.5 acres. According to the
proposed Map 2.05.3 MIA, there is only one material and equipment storage yard in the south
facilities area comprising approximately 4.0 acres. Please determine the correct number of
material and equipment storage areas and the appropriate acreage, and revise Map 2.05.3
MIA and page 2.05-13 accordingly.
4. The Transfer Building and Coal Stockpile is discussed on the proposed revised page 2.05-17.
The first sentence under the referenced heading states that, "Coal from the initial development
