Part I Page 10 of 22 <br />Permit No. COR-040000 <br />• C. STORMWATER MANAGEMENT PLAN -INACTIVE MINES (cont.). <br />3) Other pollution prevention measures: The plan shall identify any other structural and non-structural measures <br />for stormwater quality control on-site. <br />In each case where stormwater pollution potential exists, appropriate preventive measures must be identified and <br />implemented. <br />Inactive mining sites that have non-mining activity occurring (such as remediation) must also evaluate the other <br />potential sources listed in Part I.B.4.b, and must include in their SWMP the items listed in Parts I.B.4.c, d, e, f and g, as <br />applicable. <br />Comprehensive Inspection <br />The SWMP shall identify qualified personnel that shall inspect designated equipment and mine areas at appropriate intervals <br />specified in the plan, at least 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. The operator shall keep a record <br />of such inspections. This record shall be made available to the Division upon request and shall be summarized in the <br />Compliance Report (see Part I.E.1.b of the permit). <br />Additional SWMP Items for Sites Seelane Mine Remediation/Permit Termination <br />Additional requirements apply in the event that the permittee wishes to remediate the inactive mine site and terminate permit <br />coverage. If the site is already covered by this permit; the permittee shall notify the Division as to the change in status. <br />Notification shall be prior to the implementation of the remediation work, if possible. The SWMP must be amended to <br />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 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 mineralogical 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 the BMPs that will be implemented to <br />reduce the potential of remediation activities to contribute pollutants to stormwater discharges. Activities that shall be <br />addressed include, at a minimum, vehicle maintenance, earth moving, revegetation, material storage and spill <br />prevention. <br />e. Procedures for Disposal of Water Stored Within Mine Waste: The permittee must describe how any water stored <br />within the mine waste will be collected and/or routed to any storage or treatment facilities. No discharge of this water <br />shall be made to waters of the state, unless separate CDPS 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 description shall <br />include any of the following if appropriate: specifications for capping or isolation of the mine waste, method and type of <br />revegetation, and other permanent BMPs. The plan shall also include a description of the ultimate land use after <br />remediation is complete.
