PART I <br />Page No. 22 <br />Permit No.: CO-0000213 <br />- all areas of soil disturbance <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 />- stonrnwater outfalls and an approximate outline of the areas draining to each outfall; <br />- each existing and new structural control measure to reduce pollutants in Stormwater runoff; <br />- the location of impervious structures (e.g. parkittg lots, roofs, etc.); <br />-the locations of all surface water bodies, including dry water courses, located in or next to the facility; and <br />- the locations of all potential pollutant sources identified under Part I.D.2.a.iv.b. <br />iv) Stormwater Management Controls <br />Western Fuels-Colorado shall develop a description of Stormwater quality controls appropriate for that site, and <br />implement such controls. The appropriateness and priorities of controls in the plan shall reflect identified <br />potential sources of pollutants at the mining site. The description of Stormwater quality controls shall address the <br />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 <br />implementation, maintenance, and revision. The activities and responsibilities of the administrator shall <br />address all aspects of the 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 <br />to stonmwater discharges associated with mining activities. The SWMP must also describe appropriate <br />Best Management Practices (BMPs) to reduce the potential of these sources to contribute pollutants to <br />stormwater discharges. At a minimum, each of the following shall be evaluated for the reasonable <br />potential for contributing 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 />practices; and <br />- stockpiles of overburden, raw material, intermediate products, byproducts, fmished 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 <br />of toxic or hazardous pollutants. <br />The description of the BMPs shall include: <br />1) Stormwater diversion: Describe how and where Stormwater will be diverted away from material <br />handling and storage areas to prevent Stormwater contamination. <br />2) Materials handling and spill prevention: Where materials can impact Stormwater runoff, <br />practices that reduce the potential for contamination shall be described and implemented. For <br />example, materials should be stored and handled in covered areas to prevent contact with <br />Stormwater; chemicals should be stored within berms or secondary containment devices to <br />prevent leaks and spills from entering Stormwater runoff. <br />3) Sediment and erosion prevention: Describe practices that will be used to reduce erosion and <br />prevent sediment delivery to State waters. These could include structural (such as silt fences, <br />Attachment 2.05.3(3)-18-26 <br />
