PARTI Page No. 25 Permit No..: : CO-0000221 2) Materials handling and spill prevention: Where materials can impact stormwater runoff, practices that reduce the potential for contamination shall be described and implemented. For example, materials should be stored and handled in covered areas to prevent contact with stormwater, chemicals should be stored within berms or secondary containment devices to prevent leaks and spills from entering stormwater runoff. 3) Sediment and erosion prevention: Describe practices that will be used to reduce erosion and prevent sediment delivery to State waters. These could include structural (such as silt fences, sediment ponds, drop structures, check dams) and non-structural (such as mulching and revegetation) methods. In each case where stormwater pollution potential exists, appropriate preventive measures must be identified and implemented. c) Preventive Maintenance - The SWMP shall identify a preventive maintenance program. This program shall involve maintenance of stormwater management devices (maintenance of dikes separating mine drainage from stormwater, cleaning oil/water separators and catch basins, etc.) as well as inspecting and testing of equipment and systems to prevent conditions that could cause breakdowns or failures resulting in discharges of pollutants to surface waters. d) Good Housekeeping -The SWMP shall identify good housekeeping procedures that will be followed by the mining operation. Good housekeeping requires the maintenance of a clean, orderly facility. This part of the SWMP shall address cleaning and maintenance schedules, trash disposal and collection practices, grounds maintenance, etc. e) Spill Prevention and Response Procedures - Areas where potential spills can occur, and their accompanying drainage points, shall be identified clearly in the SWMP. Where appropriate, specifying material handling procedures and storage requirements in the plan shall be considered. Procedures for cleaning up spills shall be identified in the plan and made available to the appropriate personnel. The necessary equipment to implement a clean-up shall be available to personnel. f) Employee Education - The SWMP shall describe employee education programs to inform personnel at all levels of responsibility (who are involved in mining activities that may impact stormwater runoff) of the components and goals of the SWMP. Education shall address topics such as spill response, good housekeeping and material management practices. The SWMP shall identify periodic dates for such instruction. Contractor or temporary personnel shall be informed of mine operations and control features in order to prevent stormwater pollution from occurring. g) Identification of Discharges other than Stormwater - The stormwater conveyance system on the site shall be evaluated for the presence of discharges other than stormwater. The SWMP shall include a description of the results of any evaluation for the presence of discharges other than stormwater, the method used, the date of any evaluations and the on-site drainage points that were directly observed during the evaluation. A number of discharges other than stormwater may not require a CDPS Wastewater Discharge permit and are considered Allowable Non-stormwater Discharges. These are listed at Part I.D.3, below. Any of these discharges that exist at the site must be identified in the SWMP. v. Comprehensive Inspection The SWMP shall identify qualified personnel that shall inspect designated equipment and mine areas at appropriate intervals specified in the plan, at least twice a year (in the spring and fall). The operator shall keep a record of such inspections. This record shall be made available to the Division upon request and summarized in the Annual Report (see Part I.E.1 of the permit). vi. Consistency with Other Plans SWMPs may reflect requirements for Spill Prevention Control and Countermeasure (SPCC) plans under section 311 of the CWA, or Best Management Practices (BMPs) Programs otherwise required by a CDPS permit, and may incorporate any part of such plans into the SWMP by reference. The SWMP may rely upon information developed for other similar pollution control programs, including the Mined Land Reclamation Plan. Appropriate portions of these other plans may be incorporated in the SWMP by reference, as long as a complete SWMP can be reproduced and submitted to the requesting agency within the time frame specified in the request. Those portions of the referenced documents must be included in the submittal. The SWMP must also be readily available to an on-site inspector.
