Long Denver, COlOradO 80222 Division Duecto~ RE: Red Canyon Mine, CDPS ,i/ C-850020 File No. C-81-034 Dear Mr. Kubic: In a phone discussion of April 30, I described the situation regarding the sedimentation pond at the Red Canyon Mine near Cedaredge, operated by MINREC, INC. The Red Canyon Mine is a small underground coal mine, with approximately 20 acres of surface disturbance. The entire disturbed area with the exception of the sediment pond, a segment of access road, and various collection and diversion ditches, was regraded and seeded in 1988. The operator has recently applied for retention of the pond as a permanent impoundment for wildlife use. As I explained, the primary water source for the pond would be irrigation drainage water which is currently diverted around the pond. A section of the diversion would need to be re-routed to direct water into the pond, and we would like to have this work completed this year to evaluate functioning of the channel modification and impoundment prior to final bond release (anticipated in 1998). An effective vegetation cover has been established on the reclaimed site, and although the pond is still in .place, DMG approved sediment pond removal in 1992, based on sediment demonstrations made by the operator. Modification of the diversion to direct irrigation drainage water into the pond would seem to be precluded as long as the CDPS permit remains in effect. You indicated that since we determined that the pond is no longer necessary for sediment control, and its current and future use would be solely for agricultural or wildlife use, the operator would be eligible to request de-activation of the CDPS permit at this time, and the discharge permit could in fact be de- activated prior to final DMG bond release.
