PARTI <br />Page No. 27 <br />• Permit No.: CO-0000221 <br />the total acreage within the mine site-and an estimate of [he number of acres of disturbed area. A general description <br />of [he location of the mining site relative to major transportation routes and communities shall also be provided. <br />ii. Area Subject to Effluent Limitations Guidelines <br />Each plan shall describe the portion of the mining site which contributes runoff to areas subject to effluent <br />limitations guidelines contained in 40 CFR subchapter N. <br />iii. Site Map <br />Each plan shall provide a site map or maps which indicate at a minimum; <br />- mining/milling site boundaries and access and haul roads; <br />- equipment storage, fueling and maintenance areas; <br />- materials handling areas; <br />- areas used for storage of overburden, materials, soils or wastes; <br />- areas used for outdoor manufacturing, storage or disposal of materials; <br />- location of mine drainage or any other process water; <br />- tailings piles/ponds, both new and pre-existing; <br />- mine drainage or any other process water discharge points; <br />- springs, streams, wetlands and other surface waters; and <br />- boundary of area that contributes runoff [o outfalls that are subject [o effluent limitations guidelines. <br />For [hose areas outside of the area that contributes runoff to outfalls that are subject to effluent limitations guidelines <br /> - an estimate of the direction(s) of surface flow; <br /> - stormwater outfalls and an outline of the drainage area of each s[ormwater ou[fall; <br />• -each existing s[rucmral control measure to reduce pollutants in stormwater runoff; and <br />- the location of im <br />ervious structures (e <br />arking lots <br />roofs <br />etc <br />) <br /> p <br />.g. p <br />, <br />, <br />. <br /> iv. S[ormwa[er Management Controls <br /> Seneca Coal Company shall develop a description of s[ormwater quality controls appropriate for that site, and <br /> implement such controls. The appropriateness and priorities of controls in the plan shall reflect identified potential <br /> sources of pollutants a[ the mining site. The description of s[ormwater quality controls shall address the following <br /> minimum components, including a schedule for implementing such controls: <br /> a) SWMP Administrator -The SWMP shall identify a specific individual or individuals within the mining <br /> organization who is responsible for developing the S WMP and assisting the mine operator in its implementation, <br /> maintenance, and revision. The activities and responsibilities of [he administrator shall address all aspects of the <br /> facility's SWMP. <br /> b) Identification of Potenfial Pailutant Sources and Best Management Practices - The S WMP shall identify <br /> potential sources of pollutants at the site, and assess [he potential of these sources to contribute pollutants to <br /> stormwater discharges associated with mining activities. The SWMP must also describe appropriate Bes[ <br /> - Management Practices (BMPs) to reduce the potential of these sources to contribute pollutants to s[ormwater <br /> discharges. At a minimum, each of the following shall be evaluated for the reasonable potential for contributing <br /> pollutants to runoff. <br /> - loading and unloading operations, <br /> - outdoor storage of chemicals or equipment; <br /> - outdoor milling or processing activities; <br /> - historic mine drainage; <br /> - tailings ponds; <br /> - crushing facilities or significant dust and particulate generating activities; practices; and <br /> - stockpiles of overburden, raw material, intermediate products, byproducts, finished products or waste <br />• products. <br /> Factors to consider include the toxicity of the material; quantity of chemicals used; amount of material <br /> processed; the likelihood of contact with stormwater; and history of significant drainage, leaks or spills of toxic <br /> or hazardous pollutants. <br /> The description of the BMPs shall include: <br />
