7. What containment does the permittee have for materials used, processed or stored on site? A limited amount of coal was present in the central Ioadout facility. Runoff water from this area is diverted to sedimentation pond 10-A. No other storage facilities (e.g. diesel, solvents, etc.) were noted. Fuel for the equipment is provided by a tank truck. Are additional controls necessary? N Is the Materials Containment Plan adequate? N If no, explain. A materials containment plan was not available for review during the inspection. As construction just started, no stored chemicals were noted. A plan must be developed, implemented, and submitted to the Water Quality Control Division. If a plan was developed, the date it was submitted, and any updates, must be provided. 8. Describe the wastewater treatment processes: The wastewater treatment process consists of settling ponds. No chemical are proposed for use in the treatment process. Only three ponds were under construction at the time of inspection. The Colorado Division of Minerals and Geology requires that the soil for the ponds be compacted. Revegetation of the disturbed areas will be required. SECTION D: OPERATION/MAINTENANCE: 9. Evaluate the treatment facility. Include in this evaluation a discussion of any operation and maintenance problems: The settling ponds were dry as they were recently constructed and no significant precipitation had been received since then. Soil erosion into the settling ponds may make the Total Suspended Solids (TSS) difficult to control. Implementation of the soil erosion prevention practices should minimize the TSS impact. 10. How are solid wastes disposed? Could this disposal practice affect water quality, including groundwater? Please describe in detail. The coal is stored on-site until it is transported to the New Elk preparation plant. The mine overburden will would also be stored on-site as fill. It is not expected that these activities would pose a significant impact on the groundwater. 11. How are hazardous wastes disposed? Could this disposal practice affect water quality, including groundwater? Please describe in detail. No hazardous wastes were noted during the inspection. Solvents and oils from vehicle maintenance should be stored for recycling.
