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 azeas subject to effluent limitations <br />guidelines contained in 40 CFR subchapter N. <br />Site Map <br />Each plan shall provide a site map or maps which indicate at a minimum: <br />- mining/milling site boundazies and access and haul roads; <br />- equipment storage, fueling and maintenance azeas; <br />- materials handling azeas; <br />- azeas used for storage of overburden, materials, soils or wastes; <br />- azeas used for outdoor manufacruring, 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 dischazge points; <br />- springs, streams, wetlands and other surface waters; and <br />-boundary of area that contributes runoff to outfalls that aze subject to effluent limitations guidelines. <br />For those azeas outside of the azea that contributes runoff to outfalls that aze 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 azea of each stormwater outfall; <br />- each existing stmcrural control measure to reduce pollutants in stormwater runoff; and <br />-the location of impervious strucrures (e.g. pazking lots, roofs, etc.) <br />4. Stormwater Management Controls <br />Each mining operation certified under by this permit shall develop a description of stormwa[er 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 dischazges 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 />dischazges. At a minimum, each of the following shall be evaluated for the reasonable potential for contributing <br />pollutants to mnoff: <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 />
