PART I Page 6 of 20 <br /> Permit No. COR-040000 <br /> B. STORMWATER MANAGEMENT PLAN-ACTIVE MINES (cont.) <br /> 2. 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 limitations <br /> guidelines contained in 40 CFR subchapter N. <br /> 3. 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 to outfalls that are subject to effluent limitations guidelines. <br /> For those areas outside of the area that contributes runoff to outfalls that are subject to effluent limitations <br /> guidelines: <br /> - an estimate of the direction(s) of surface flow; <br /> - stormwater outfalls and an outline of the drainage area of each stormwater outfall; <br /> - each existing structural control measure to reduce pollutants in stormwater runoff; and <br /> - the location of impervious structures (e.g. parking lots, roofs, etc.) <br /> 4. Stormwater Management Controls <br /> Each mining operation certified under by this permit shall develop a description of stormwater quality controls <br /> appropriate for that site, and implement such controls. The appropriateness and priorities of controls in the plan shall <br /> reflect identified potential sources of pollutants at the mining site. The description of stormwater quality controls shall <br /> address the following 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 SWMP and assisting the mine operator in its implementation, <br /> maintenance, and revision. The activities and responsibilities of the administrator shall address all aspects of the <br /> facility's SWMP. <br /> b. Identification of Potential Pollutant Sources and Best Management Practices- The SWMP shall identify <br /> potential sources of pollutants at the site, and assess the potential of these sources to contribute pollutants to <br /> stormwater discharges associated with mining activities. The SWMP must also describe appropriate Best <br /> Management Practices (BMPs) to reduce the potential of these sources to contribute pollutants to stormwater <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; <br /> - on-site waste disposal practices; and <br /> - stockpiles of overburden, raw material, intermediate products, byproducts, finished products or waste <br /> products. <br />
