The accidental spill from a holding pond at the Standard Mine reclamation project west of Crested Butte is not expected to have any negative impact on the town’s drinking water.
The spill occurred late Wednesday and is believed to have involved approximately 2,000 gallons of water and gray-colored sediment. An EPA contractor accidentally released the sediment into Elk Creek as he was dewatering a sediment pond. Based on the neutral pH levels, the quantity of water released, and flow levels downstream in Coal Creek, the Town of Crested Butte did not close its water intakes. Subsequent investigation found no visible plume or signs of significant impacts in downstream locations. All work on the sediment pond is complete. The EPA continues to coordinate closely with Crested Butte officials on this matter.
