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 <br />or 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 he 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 <br />to 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 mine <br />waste, method and type of revegetation, and other permanent BMPs. The plan shall also include a description of <br />the ultimate land use after remediation is complete. <br />vi. Consistency with Other Plans <br />SWMPs may reflect requirements for Spill Prevention Control and Countermeasure (SPCC) plans under section 311 <br />of the CWA, or Best Management Practices (BMPs) Programs otherwise required by a CDPS permit, and may <br />incorporate any part of such plans into the SWMP by reference. The SWMP may reflect information contained in <br />approved plans submitted for other similar pollution control programs, including the Voluntary Clean Up Program. <br />(Voluntary Cleanup and Redevelopment Act, CRS 25 -16 -303) as long as they contain the elements described above. <br />These plans must have been approved by the implementing agency prior to application for the Stormwater Permit. <br />Appropriate portions of these other plans may be incorporated in the SWMP by reference, as long as a complete <br />SWMP can be reproduced and submitted to the requesting agency within the time frame specified in the request. <br />Those portions of the referenced documents must be included in the submittal. The SWMP must also be readily <br />available to an on -site inspector. <br />b. General Limitations <br />The following limitations shall apply to all discharges authorized by this permit: <br />i. Stormwater discharges from mining operations or mine -waste remediation projects shall not cause or threaten to <br />cause pollution, contamination or degradation of State waters. <br />ii. Bulk storage structures for petroleum products and other chemicals shall have adequate protection so as to contain <br />all spills and prevent any spilled material from entering State waters. <br />iii. No chemicals are to be added to the discharge unless permission for the use of a specific chemical is granted by the <br />Division. In granting the use of such chemicals, special conditions and monitoring may be addressed by separate <br />letter. <br />iv. All dischargers must comply with the lawful requirements of counties, drainage districts and other state or local <br />agencies regarding any discharges of stormwater to storm drain systems or other water courses under their <br />jurisdiction. <br />c. SWMP Requirements <br />i. SWMP Submittal/Review /Changes: The Division reserves the right to request and review the plan, and to require <br />additional measures to prevent and control pollution, as needed.
