Stormwater Requirements (continued) <br />1) Description of Minintt Activities <br />The plan shall provide a rarrative description of the mining and associated activities that took place at the site. <br />The narrative description shall report the approximate dates of operation, the total acreage within the mine site <br />and an estimate of the number of acres of disturbed area. A general description of the location of the mining <br />site relative to major transportation routes and communities shall also be provided. <br />2) Site Map <br />Each plan shall provide a generalized site map or maps which indicate any of the following which may be <br />applicable: <br />- mining/milling site boundaries and access and haul roads; <br />- areas used for storage of overburden, materials, soils, tailings or wastes; <br />- areas used for outdoor manufacturing, storage or disposal of materials; <br />- tailings piles and ponds; <br />- an estimate of the dtrection(s) of surface flow; <br />- existing structural control measures to reduce pollutants in stormwater runoff; and <br />- springs, streams, wetlands and other surface waters. <br />3) Stormwater Management Controls -Identification of Sources and Best Management Practices <br />. The SWMP shall identify potential sources of pollutants at the site and assess the potential of these sources to <br />contribute pollutants to stormwater discharges associated with mining activities. The SWMP must also describe <br />appropriate Best Management practices (BMPs) to reduce the potential of these sources to contribute pollutants <br />to stormwater dischazges. The appropriateness and prioriries of controls in the plan shall reflect identified <br />potential sources of pollutants at the mining site. The description of the BMPs shall include: <br />a) Stormwater Diversion: Describe how and where stormwater will be diverted away from potential pollutant <br />sources to preveat stormwa[er contamination. <br />b) Sediment and Erosion Prevention: Describe practices that will be used to reduce erosion and prevent <br />sediment delivery to State waters.
