• 4.1 I COAL PROCESSING WASTE <br />Colowyo does n-ot have a coal preparation facility, therefore the requirements of certain parts <br />of this Section are not applicable to Colowyo. <br />4.11.1 Burnine <br />(Not Applicable) <br />4.11.2 Burned Waste Utilization <br />(Not Applicable} <br />4.1 I.3 Return to Underground Workines <br />(Not Applicable) <br />4.11.4 Disnosal of Noncoal Waste <br />Noncoal, nonhazardous solid waste, such as garbage, used tires, etc., is stored in a controlled <br />manner around the operation in various waste receptacles and waste locations. Periodically <br />the waste is disposed of in the backfill area of the pit and covered with a minimum twenry- <br />five feet of overburden material. No waste is allowed on the bottom of the backfill area or <br />below the anticipated groundwater level of backfilled areas. <br />Facility structures including but not limited to concrete foundation will be demolished in- <br />place and covered with a minimum of six feet of suitable material. The area will be regraded <br />to blend with the surrounding topography followed by topsoil and seeding as described in the <br />reclamation plan. Alt demolition materials related to sedimentation ponds will be placed <br />within the ponds a covered with a minimum of six feet of suitable material or transported to <br />the pit area during the reclamation process. Noncoal, nonhazardous solid waste is regulated <br />under the Moffat County Special Use permit identified in Section 2.03.10. <br />Nonhazardous used oil and grease, flammable liquids, etc. are stored in a tankfarm facility <br />located near the shop facilities. <br />Colowyo's status as a conditionally exempt small quantity generator of hazardous materials <br />essentially indicates that Colowyo generates negligible amounts of hazardous waste. The <br />limited amount of hazardous waste is handled according to applicable State and Federal <br />requirements. <br />Waste water from toilets, sinks, and showers will be disposed of by means of septic tanks, <br />underground leach fields and evaporation ponds. <br />Portable self-contained toilets will be located around the operation. These portable toilets <br />will be serviced periodically and the waste hauled from the mine for disposal. <br />4.11-1 Revision Date: 9/1/05 <br />Revision No.: MR-74 <br />
