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 <br />implemented to reduce the potential of remediation activities to contribute pollutants to stormwater <br />discharges. Activities that shall be addressed include vehicle maintenance, earth moving, material <br />storage and spill prevention. <br />e) Procedures for Disposal of Water Stored Within Mine Waste: The permittee must describe how any <br />water stored within the mine waste will be collected and/or routed to any storage or treatment facilities. <br />No discharge of this water shall be made to waters of the state, unless separate permit coverage is <br />obtained. <br />fl Description of Permanent BMPs, Final Site Stabilization, and Ultimate Land Use: The plan shall <br />include a description of the specific permanent measures that will be installed or used at the mine-waste <br />site. The description shall include any of the following if appropriate: specifications for capping or <br />isolation of the mine waste, method and type of revegetation, and other permanent BMPs. The plan <br />shall also include a description of 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 secondary containment or other <br />equivalent protection adequate protection so as to contain all spills and prevent any spilled material from entering <br />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 <br />the 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 />Attachment 2.05.3(3)-18-28 <br />
