1 ' r, <br />APPENDIX C {cont.) <br />5. Additional SWMP Items for Sites Seeking Permit Termination <br />In the event that the permittee wishes to remediate the inactive mine site and terminate permit <br />coverage, the SWMP must be amended to include the following items: <br />a. Documentation of Permission: The plan shall include documentation of permission from the <br />land owner, if the 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 <br />site before any remedial action has occurred. For recently active mines, photographs of the <br />active mining phase may be substituted. <br />c. Description of Remedial Action: The plan shall describe the remedial action that will take place <br />to minimize or eliminate the water quality impacts from the mine waste. The description shall <br />include: <br />- Remediation Croal Statement; <br />- the characteristics of the mineralogic content of the mine-waste, and estimated volume of <br />the waste; <br />- description of any materials that will be mixed into the mine waste on site; <br />- estimated surface azea 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 pennittee must descn`be <br />how any water stored within the mine waste will be collected, routed to any storage or treatment <br />facilities. No discharge of this water shall be made to waters of the state, unless sepazate permit <br />coverage is obtained. <br />f. Description of permanent BMPs, final site stabilization, and ultimate land use: The plan <br />shall include a description of the specific 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 <br />or isolation of the mine-waste, method and type of revegetation, and other permanent BMPs. The <br />plan shall also include a description of the ultimate land use after remediation is complete. <br />6. Consistency with Other Plans <br />SWMPs may reflect requirements for Spill Prevention Control and Countermeasure (SPCC) plans <br />under section 311 of the CWA, or Best Management Practices (BMPs) Programs otherwise required <br />by a CDPS permit, and may incorporate any part of such plans into the SWMP by reference. The <br />SWMP may refect information contained in approved plans submitted for other similar pollution <br />control programs, including the Voluntary Clean Up Program. (Voluntary Cleanup and <br />Redevelopment Act, CRS 25-16-303} as long as they contain the elements described above. These <br />plans must have been approved by the implementing agency prior to application for the Stormwater <br />Permit. Appropriate portions of these other plans may be incorporated in the SWMP by reference, <br />as long as a complete SWMP can be reproduced and submitted to the requesting agency within the <br />time frame specified in the request. Those portions of the referenced documents must be included in <br />the submittal. The SWMP must also be readily available to an on-site inspector. <br />7/96/lhm C-5 <br />
