PART I Page 9 of 20 <br /> Permit No. COR-040000 <br /> C. STORMWATER MANAGEMENT PLAN-INACTIVE MINES (cont.) <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 to <br /> stormwater discharges. The appropriateness and priorities of controls in the plan shall reflect identified potential <br /> 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 prevent stormwater contamination. <br /> b. 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 structures, <br /> check dams) and non-structural (such as mulching and revegetation) methods. <br /> 4. Comprehensive Inspection <br /> The SWMP shall identify qualified personnel that shall inspect designated areas. Inspections required by this part <br /> shall be conducted annually. Where annual inspections are impracticable, certification is required once every three <br /> years by a Registered Professional Engineer that the site is in compliance with the SWMP. <br /> 5. Additional SWMP Items for Sites Seeking Permit Termination <br /> Additional requirements apply in the event that the permittee wishes to remediate the inactive mine site and terminate <br /> permit coverage. If the site is already covered by this permit, the permittee shall notify the Division as to the change <br /> in status. Notification shall be prior to the implementation of the remediation work, if possible. The SWMP must be <br /> amended to include the following items, prior to implementation of the remediation work, if possible: <br /> a. Documentation of Permission: The plan shall include documentation of permission from the land owner, if the <br /> remediation work is undertaken by someone other than the land owner. <br /> b. Photographs: The plan shall include photographs documenting the condition of the inactive mine site before any <br /> remedial action has occurred. For recently active mines, photographs of the active mining phase may be <br /> substituted. <br /> c. Description of Remedial Action: The plan shall describe the remedial action that will take place to minimize or <br /> eliminate the water quality impacts from the mine waste. The description shall include: <br /> - Remediation Goal Statement; <br /> - the characteristics of the mineralogic content of the mine-waste, and estimated volume of the waste; <br /> - description of any materials that will be mixed into the mine waste on site; and <br /> - estimated surface area of the final site, and estimated angle of side slopes. <br /> d. Description of BMPs during Remediation Activities: The plan shall describe BMPs that will be implemented to <br /> reduce the potential of remediation activities to contribute pollutants to stormwater discharges. Activities that <br /> shall be addressed include vehicle maintenance, earth moving, material storage and spill prevention. <br /> e. Procedures for Disposal of Water Stored Within Mine Waste: The permittee must describe how any water <br /> stored within the mine waste will be collected and/or routed to any storage or treatment facilities. No discharge <br /> of this water shall be made to waters of the state, unless separate permit coverage is obtained. <br /> f. Description of Permanent BMPs, Final Site Stabilization, and Ultimate Land Use: The plan shall include a <br /> description of the specific permanent measures that will be installed or used at the mine-waste site. The <br /> description shall include any of the following if appropriate: specifications for capping or isolation of the <br />
