PARTI <br />Page No. 9 <br />Permit No.: CO-0036251 <br />~. SPECIAL REQUIREMENTS <br />2. StormwaterReguirements <br />b. Stormwater Management Plan -Contents and Requirements (Continued) <br />iii) Site Map <br />Each plan shall provide a site map or maps which indicate at a minimiun: <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 azeas outside of the area that contributes runoff to outfalls that are subject to effluent limitations guidelines: <br />- an estimate of the duection(s) of surface flow; <br />- stormwater outfalls and an outline of the drainage azea of each stormwater outfall; <br />- each existing structural control measure to reduce pollutants in stormwater runoff; and <br />- the location of impervious stmctures (e.g. pazking lots, roofs, etc.) <br />iv) Stormwater Management Controls <br />The Cotter Corporation shall develop a description of stormwater quality controls appropriate for the site, and <br />implement such controls. The appropriateness and priorities of controls in the plan shall reflect identified potential <br />sources of pollutants at the mining site. The description of stormwater 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 SWMP and assisting the none 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 />storrriwater 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 nrhrimum, 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 />- crashing facilities or significant dust and particulate generating activities; <br />- on-site waste disposal practices; and <br />- stoclcpIles of overburden, raw material, intermediate products, byproducts, fuushed products or waste <br />products. <br />
