ti ~: Colorado Yampa Coal Company June 7, 1985 ~II II~II~II~~I~~ II~ CYCC 29588 Routt County Road #27, Oak Creek, CO 80467 • (303) 879-3800 RECEIVED Mr. Dan Mathews JUN 1 01985 Colorado Mined Land Reclamation Division 423 Centennial Building MINED LAND 1313 Sherman Street RECLAMATION DIVISION Denver, Colorado 80203 Re: Alleged N.O.V. C-85-045, Mine No. 3, Permit C-84-062 Dear Mr. Mathews: Colorado Yampa Coal Company (CYCC) is submitting the following informa- tion concerning the above referenced alleged violation which was issued to CYCC on May 24, 1985. The alleged violation was issued for "failure to con- struct sediment control facilities in compliance with approved design. Speci- fically, collection ditch P-1 along base of Middle Creek pit rough graded spoils has not been constructed and required dewatering device has not been installed in the Middle Creek Detention Basin." In light of the immediate review and cursory engineering designs recently conducted, it is evident that the presently approved sediment control facili- ties, ditch P-1 and the Middle Creek Detention Basin is not a practical long- term solution to the sediment control issue at the Middle Creek Pit area. CYCC requests that the abatement date of alleged violation C-85-045 be extended from June 20, 1985 to August 22, 1985. Justification for such re- quest is as follows: 1. The entire Middle Creek Pit area needs to be surveyed to establish present topography. 2. New engineering designs need to be developed for a new sediment control plan for the area. 3. The new sediment control plan needs to be submitted to and approved by CMLRD prior to implementation. 4. Evaluations of modified primary dewatering devises need to be con- ducted. 5. New engineering designs associated with the primary dewatering de- vise needs to be completed. 6. The new engineering designs associated with the primary dewatering devise needs to submitted to and approved by CMLRD prior to imple- mentation.
