PART I Page'6 of 20 ~ - <br />Permit No. COR-040000 <br />B. STORNIWATI'sR 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 <br />limitations guidelines contained in 40 CFR subchapter N. <br />Site Mao <br />Ea:dt plan shall provide a site map or maps which indicate at a minimum: <br />- mininglmilling site boundazies and access and haul roads; ' <br />- equipment storage, fueling and maintenance seas; <br />- materials handling areas: <br />- aze:u used for storage of overburden, materials, soils or wastes; <br />- aze:ts used for outdoor manufacturing, storage or disposal of materials; <br />- locuion of mine drainage or any other process water; <br />- tailings piles/ponds, both new and preexisting; <br />- mine drainage or any outer process water dischazge points; ' <br />- springs, streams, wetlands and other surface waters; and <br />- boundary of azea thaz contributes runoff to outfalls that aze subject to effluent limitations guidelines. <br />w <br />For those seas 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 azea of each stormwater outfall; t <br />- each existing structural control measure to reduce pollutants in stormwater nmoff; and • <br />- the location of impervious structures (e.g. pazlcing lots, roofs, etc.) <br />4. Stormwater Management Controls <br />i <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 corurols. The appropriateness and priorities of controls in the plan <br />shall reflect identified potential sources of pollutants at the mining site. The description of stormwater quality <br />controls shall 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 />organvation 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 <br />the facility's SWMP. <br />b. Identification of Potential Pollutant Sources and Best Management Practices -The SWMP shall identify <br />potential sources of pollutants az the site, and assess the potential of these sources to contribute pollutants to <br />stonnwater dischazges associated with mining activities. The SWMP mast also describe appropriate But <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 contribuimg <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 />
