EFFLUENT LIIvIITATIONS AND MONTIORIIVG REQUII2EMENfS <br />2. stormwater Management Plan (SWMP) <br />A stormwater Management Plaa (SWMP) shall be developed for the portion of each facility coveted by this section of <br />the permit. The SWMP shall be ptrpazed in accordance with good engineering practices. ('Ihe plan need no[ be <br />completed by a registered engineer.) <br />Tire plan shall identify potential sources of pollution (including sediment) which may reasonably be expected to affect the <br />quality of stormwater dischazges associated with the mining operation. In addition, the plan shall describe and ensure <br />the implementation of best management practices (BMPs) which will be used to reduce the pollutants in stormwaer <br />ducharges associated with mining activity. <br />Mining operations must implement the provisions of the SWMP required under this part as a condition of this <br />permit. The-0ivision reserves the righ[ to request and review the plans; and to require additional measures to prevent <br />and control pollution, as needed. <br />The SWMP shall describe all areas that have not been previously permitted, and which mat the defmition of a <br />stormwater duchazge in 40 CFR 122.26. Examples of such arras are roads and railroad lines used for transportation to <br />and from the site, outslopes of ponds, inactive loadoua, sites used for storage and maiartnance of material handling <br />equipment, and areas granted small arw exemptions. <br />a) SNMP Contents <br />The SWMP shall indudc the following items, at a minimum: <br />1) Site Map <br />The plan shall provide a site map or maps which indicate, at a minimum: <br />- Mitring si[e boundaries <br />- Access and haul roads <br />- stormwater outfalls and an outline of the drainage area of each stormwater outfall <br />- An estimate of the direction of flow <br />- Materials handling areas <br />- Each existing s¢uctural control measure m reduce pollutants in stormwater runoff <br />- Areas used for storage or disposal of overburden, materials, soils or wastes, including tailings pits or <br />Ponds <br />- Atlas used for mineral milling and processing <br />- Springs, streams, wetlands and other surface wazers <br />- Location of mine drainage or any other process wazer dischazge points <br />- boundary of area thaz contributes runoff to outfalls thaz ate subject to effluent limitations guidelines. <br />- Date the map was prepazed <br />2) Description of Potential Pollutan[ SourceslMaterial Saventory <br />The plan shall provide a description of all potential sources (activities and mer..;~[e) which may reasonably be <br />expected to add pollutanu to stormwaer discharges. Such sources may include haul roads, equipment storage <br />and maintenance aeeas, fuel storage areas, etc. <br />Ia each case where stormwater pollution potential exists, appropriate prevemive m~ai*rc tenter be taken and <br />documented. <br />
