RULE 4 PERFORMANCE STANDARDS <br />4.11 Coal Processing Waste <br />Colowyo does not have a coal preparation facility, therefore the requirements of certain parts of this <br />Section are not applicable to Colowyo. <br />4.11.1 Burning <br />(Not Applicable) <br />4.11.2 Burned Waste Utilization <br />(Not Applicable) <br />4.11.3 Return to Underground Workings <br />(Not Applicable) <br />4.11.4 Disposal of Noncoal Waste <br />Noncoal, nonhazardous solid waste, such as garbage, used tires, etc., is stored in a controlled manner <br />around the operation in various waste receptacles and waste locations. Periodically the waste is disposed <br />of in the backfill area of the pit and covered with a minimum twenty-five feet of overburden material. No <br />waste is allowed on the bottom of the backfill area or below the anticipated groundwater level of <br />backfilled areas. <br />Facility structures including but not limited to concrete foundation will be demolished in-place and <br />covered with a minimum of six feet of suitable material. The area will be regraded to blend with the <br />surrounding topography followed by topsoil and seeding as described in the reclamation plan. All <br />demolition materials related to sedimentation ponds will be placed within the ponds a covered with a <br />minimum of six feet of suitable material or transported to the pit area during the reclamation process. <br />Noncoal, nonhazardous solid waste is regulated under the Moffat County Special Use permit identified in <br />Section 2.03.10. <br />Nonhazardous used oil and grease, flammable liquids, etc. are stored in a tankfarm facility located near <br />the shop facilities. <br />Colowyo's status as a conditionally exempt small quantity generator of hazardous materials essentially <br />indicates that Colowyo generates negligible amounts of hazardous waste. The limited amount of <br />hazardous waste is handled according to applicable State and Federal requirements. <br />Waste water from toilets, sinks, and showers will be disposed of by means of septic tanks, underground <br />leach fields and evaporation ponds. <br />Portable self-contained toilets will be located around the operation. These portable toilets will be serviced <br />periodically and the waste hauled from the mine for disposal. <br />4.11.5 Dams and Embankments <br />(Not Applicable) <br />Rule 4 Performance Standards 4.11-1 Revision Date: 6/23/08 <br />Revision No.: MR-91
