' Bear Coal Company <br /> Stormwater Management Plan <br /> Page 3 ' <br />' <br /> 2 ) Unpaved road and disturbed areas on site will be <br /> watered or treated with chemical palliatives. <br />' Speeds are limited to 15 mph on all roads. <br /> 3) Vegetation will be the primary sediment control <br /> feature for stormwater runoff from the sediment <br />pond and topsoil pile outslopes. If rills occur on <br /> the slopes they will be repaired. Vegetation will <br /> be reseeded and mulched if necessary. <br /> <br /> 4) Sediment must be periodically removed from the <br /> sediment control structure. <br />' d. Good Housekeeping: The good housekeeping requirement for <br />this plan consists of performing the required preventive <br />maintenance as follows: 1) maintaining the sediment <br />control structure; and 2) maintaining water sprays and <br />surface moisture in the coal stockpiles and plant roads. <br />' e. Spill Prevention and Response Procedures: There are no <br /> areas where potential spills could occur outside of the <br /> portion of the operation that contributes runoff to areas <br />' subject to effluent limitation guidelines. <br /> f. Best Management Practices: <br /> 1) There are no areas where stormwater needs to be <br /> diverted away from material handling and storage <br /> areas to prevent stormwater contamination. <br />' <br /> 2) Materials handling and spill prevention practices <br /> are not required because there are no areas where <br /> potential spills could occur that would contribute <br /> pollutants to stormwater runoff. <br /> 3) Sediment and erosion prevention is required in two <br />' types of areas. The two areas include the haul <br /> road drainage and the drainage from the outslopes <br /> of the ponds and topsoil pile. <br />' The haul road drainage ditch collects runoff from <br /> the road and from drainage areas adjacent to the <br />' road. A ditch turnout is located where the ditch <br />exits the haul road an discharges down a bank and <br /> into the North Fork of the Gunnison River. The <br /> ditch turnout directs the stormwater flow from the <br />' haul road drainage ditch into a sediment fence, <br /> straw bale check dam or other similar structure. <br />;1 <br />~' <br />
