PART-1 <br />Page No. 14 <br />Pertmt No. COG-850000 <br />2. Description of Potential Pollutant Sources/Material Inventory <br />Identification of Potential Pollutant Sources and Best Management Practices The SWMP shall identify potential <br />sources of pollutants at the site, and assess the potential of these sources to contribute pollutants to stormwater <br />discharges associated with mining activities. The SWMP must also describe appropriate Best Management Practices <br />(BMPs) to reduce the potential of these sources to contribute pollutants to stormwater discharges. At a minimum, each <br />of the following shall be evaluated for the reasonable potential for contributing pollutants to runoff- <br />- haul roads <br />- loading and unloading operations; <br />- maintenance areas <br />- outdoor storage of fuels, chemicals or equipment; <br />- outdoor ore processing activities; <br />- crashing facilities or significant dust and particulate generating activities; <br />- on site waste disposal practices; <br />- stockpiles of overburden, raw material, intermediate products, byproducts, finished products or waste products; and <br />- disturbed areas. <br />Factors to consider include the toxicity of the material; quantity of chemicals used; amount of material processed; the <br />likelihood of contact with stormwater; and history of significant drainage, leaks or spills of toxic or hazardous <br />pollutants. <br />The description of the BMPs shall include: <br />a. Stormwater diversion: Describe how and where stormwater will be diverted away from material handling and <br />storage areas to prevent stormwater contamination. <br />b. Materials handling and spill prevention: For materials that could impact stormwater runoff, all existing and <br />planned BMPs that prevent the contamination of stormwater runoff at the site shall be included and described. <br />c. Sediment and erosion prevention: Describe practices that will be used to reduce erosion and prevent sediment <br />delivery to State waters. These could include structural (such as silt fences, sediment ponds, drop strictures, <br />check darns) and non-structural (such as mulching and revegetation) methods. <br />d. Other pollution prevention measures: The plan shall identify any other structural and non-structural measures for <br />stormwater quality control on-site. <br />In each case where stormwater pollution potential exists, appropriate preventive measures must be identified and <br />implemented. <br />3. Stormwater Quality Controls <br />Each mining site covered by this permit shall develop a description rrities tof controls in the plan shall effect id identified <br />site, and implement such controls. The appropriateness and pro <br />potential sources of pollutants at the 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(s), position or title who is responsible for <br />developing the SWMP and assisting the mine operator in its implementation, maintenance, and revision. <br />and <br />b. Preventive Maintenance - A preventive maintenance program is required, and shall involvee inspection <br />from <br />mine <br />maintenance of stormwater management controls (maintenance of dikes separating <br />stormwater, cleaning oil/water separators and catch basins, etc.) as well as inspecting and testing of equipment <br />and systems to prevent conditions that could cause breakdowns or failures resulting in discharges of pollutants to <br />surface waters. These periodic inspections are different from the comprehensive site evaluation (see Pat I-C-sue <br />although the former may be incorporated into the latter. Equipment, area, or other inspections are typically <br />and are normally conducted on a regular basis (e.g., daily inspections of loading areas). <br />c. Good Housekeeping - The SWMP shall identify good housekeeping procedures that will be followed by the <br />mining operation Good housekeeping requires the maintenance of a clean, orderly facility. This part of the <br />SWMP shall address cleaning and maintenance schedules, trash collection and disposal practices!, grounds
