iii ii iiu iii ~vcc Yampa Valley Coal Corporation 29588 Routt County Road X27 ,July 15, 1986 Oak Creek, Colorado 80467 (303) 879-3800 Mr. Dan Mathews Reclamation Specialist Colorado Mined Land Reclamation Division 423 Centennial Building 1313 Sherman Street Denver, Colorado 80203 RE: Response to Stipulation No. 15, Mine No. 3 Permit C-84-062 Dear Mr. Mathews: Stipulation 15 states that the permitee shall provide the Division, to be .incorporated into the permit document, a plan for controlling sediment from the distrubed area above the Homestead irrigation ditch. Colorado Yampa Coal Company (CYCC) will implement the same sediment control/soil stabilization measures for the small area exemption as it is for the balance of the approved Mine No. 3 reclamation plan. These measures are chiselling, seeding with a pastureland mixture and contour furrowing. All three of these soil stabilization practices were initiated in the fall of 1983, with the reconstruction of contour furrows occurring during each subsequent season. CYCC is confident that the reconstruction of contour furrows will satisfy CMLRD concerns, and suggests that during an upcoming inspection the CMLRD walk the small area exemption above the Homestead ditch. If the CMLRD still has serious concerns over this area a solution will be reached during the inspection and will be implemented prior to the next inspeciton. In regards to your letter dated April 4, 1985, suggesting straw bale berms above the small area exemption, CYCC feels that the poor success seen in our permanent gullies at Mine 1 and Eckman Park due to elk browsing does not justify continued use of straw bales. Other secondary sediment control practices are available to control sediment if the area shows significant sediment loss, however, this is not the case in the small area exemption.
