Department of Natural Resources ~ ,. .; ;, 1313 Sherman Street, Room 423 Denver, CO 80203-2273 RE: Snowmass Coal Company, Reconstruction of Refuse Site Sedimentation Pond, Permit No. 77-313 Dear Mr. Liddle: When I started working for Snowmass Coal in August of 1982, construction was under way on the new refuse area sediment pond. During the construction project, we experienced an unusual number of days of rain and snowfall. While the rain and snow was not heavy it persisted for three or four days at a time. We found that it was almost impossible to achieve the 95% compaction of the lifts due to the high moisture content of the soil. In addition, our heavy equipment used to construct the pond were constantly becoming stuck in the mud and snow. These factors forced us to delay construction of the pond for two or three days after every percipitation event in order to let the soil dry up. When I took over Craig Sherwood's position here at Snowmass, I was un- aware of the time limit that you stated in your letter of May 10, 1982. I did not become aware of this time limit until I discussed the situation with you last week. I realize that you are concerned about the runoff next spring. Therefore, I hereby submit the following plan to allow Snowmass Coal extra time in which to complete the pond. Since the pond is almost completed except far the spillways and a little more earthwork, Snowmass Coal proposes to have a registered engineer certify the existing portion of the pond. The ditches and culverts now leading to this pond will be checked weekly to make sure they are not obstructed. When the spring runoff has started, the water level of the pond will be checked every day. As soon as the water level reaches 80% of its existing volume, the water will be pumped from the pond into a water truck. The water truck will then truck the water to one of the other disturbed water ponds (Pl or P9), and discharge its water. As soon as it is feasibly possible, the pond will be completed to the specifications it was designed to.
