[II. Comments - Compliance Below are comments on the inspection. The comments include discussion of ooservations made during tfie inspection. Comments also describe any enforcement actions taken during the inspection and the facts or evidence supporting the enforcement action. sample will be analyzed at the Colorado Department of Health laboratories. The West Ridge pond contained water but was not discharging. The Center Ridge pond was discharging clear water, at a rate of approximately 100 gpm. The Moffat Pond was discharging clear water at a rate of approximately 150 gpm. There was a considerable amount of water flowing into the pond through dewatering of the Moffat pit. The pond is sized for dewatering the Moffat pit since water in the pit is not groundwater inflow, but is surface water runoff from lands included in the pond watershed. The operator was conducting NPDES sampling on the discharging ponds during the inspection. Berms and ditches designed to protect the hydrologic balance were inspected. NOV C-93-023 was issued for failure to pass disturbed area drainage through a sedimentation pond. The Trout Creek water pump disturbance area had no sedimentation control practices in place. Drainage from the pad was flowing directly to Trout Creek. Backfill and Grading was current (within two spoil ridges of the active pit) in the Moffat area. One dozer was working toward final grade in the West Ridge area. Explosives magazines were in good condition and were secured. No blasts were observed during the inspection. Support Facilities - The office, tipple, and loadout facilities were inspected. Culvert and ditch maintenance items were identified and the work carried out prior to the close of the inspection, with the exception of perimeter marker repairs. No other problems were noted in these areas. The shop buildings and yard were inspected. Surface water runoff was, for the most part, controlled by a berm on the east side, and ditches on the west side. A culvert was in place at the fuel pumps. There is currently no approved design for those structures. NOV C-93-025 was issued for failure to include descriptions and designs of each existing structure for which there are specific designs required. The approved plan shows only a berm on the west side of the coal stockpile. That berm was not constructed as designed, resulting in the issuance of NOV C-93-027, for failure to construct and maintain sediment control structures as designed. Snow removal equipment had pushed coal over the berm on the east side of the shop pad, into an undisturbed area. NOV C-93-026 was issued for failure to provide protection for topsoil and vegetation, and for a failure to retain sediment within disturbed areas. Edna Strip Mine 3 3/30/93 - 4/2/93
