D-portal Pond 1 (DP-1) -this pond serves as the main sediment control structure to catch and contain runoff from the general mine facilities area (D-portal area). At the time of evaluation, the pond resembled a wetland as there was plenty of vegetation (cattails, etc.) and the mine representative indicated that it was nearing time to clean the pond out. Nevertheless, the pond was in compliance with the approved permit and State regulations. There was no indication of seepage on the dam adjacent to the pond and there was no discharge from the 8-10 foot culvert on the dam side of the pond that drains into Scullion Gulch. The emergency spillway of the pond was also cleaz and there was no evidence of erosion or contribution of suspended solids to stream flow. For clarification purposes, the mine representative stated that the B portal is part of the D-portal Area. 2. General Facilities Area and Fan -all runoff for this area reports to DP-1; there were no indications of erosion or sediment deposition. 3. Underground Laydown Area -the runoff for this area also reports to DP-1; there were no indications of erosion or sediment deposition. The adjacent drainage ditch, which also runs to DP-1, was dry as was the ditch on the other side of the road. The DMG representative reminded mine staff that the ditches were to be kept clear of trash and debris. 4. Wash Plant Pad Area -previously, OSM had taken issue with erosion in the ditch leading from this area to DP-1. As a result, the operator has added cobblestone rip-rap to stabilize the ditch. OSM was satisfied with this mitigation effort and no erosion or siltation concerns have occurred since. 5. Moon Lake Laydown Area -runoff form this area reports to DP-1 and no erosion or siltation concerns were identified. 6. Sewage Treatment Plant Process Pond 1 (PP1) -this pond catches runoff from the surrounding area and water from the plant is also pumped to the pond. The pond was fairly full of water (ducks were on the pond) and there were no signs of discharge. If a discharge does occur, it is shipped underground to the "D" mine workings. Overland Conveyor System -Transfer Station No. 1 (TS-1) -the conveyor system was evaluated from the general facilities area to the Railroad Loadout Facility. At TS-1, runoff reports to a grassy area which serves as a "grass filter." The main concern with the transfer stations, or the points where the conveyor belt turns over and runs back to the mine and processing facilities, involves fugitive coal and fugitive coal dust. However, the conveyor itself is covered to control and minimize the potential for impacts associated with fugitive coal. Consequently, TS-1 was very clean with very little coal on the ground and even less potential for dust. The culvert underlying the road next to the conveyor was dry and the surface of the "pooling area" at the mouth of the culvert was cracked.
