Part I Page 8 of 22 Permit No. COR-040000 ??. STORMWATER MANAGEMENT PLAN - ACTIVE MINES (cont.) 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. 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 shall be summarized in the Annual Report (see Part I.E. La of the permit). 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. C. STORMWATER MANAGEMENT PLAN - INACTIVE MINES A Stormwater Management Plan (SWMP) shall be developed for each inactive mine covered by this permit. The SWMP shall include best management practices (BMPs) that are selected, installed, implemented and maintained in accordance with good engineering practices. (The plan need not be completed by a registered engineer.) The plan shall identify potential sources of pollution (including sediment) which may reasonably be expected to affect the quality of stormwater discharges associated with the inactive mining operation. In addition, the plan shall describe and ensure the implementation of BMPs which will be used to reduce the pollutants in stormwater discharges associated with the inactive mining operation and to assure compliance with the terms and conditions of this permit. Inactive mining operations must implement the provisions of their SWMP as a condition of this permit. The Division reserves the right to review the plan, and to require additional measures to prevent and control pollution as needed. Any SWMP prepared before September 30, 2006 that does not meet all of the requirements listed herein (especially those items required for the site map) must be amended to conform with the SWMP requirements in this permit. Such amendments must be completed within 60 days of the certification effective date (which is typically October 1, 2006). The SWMP shall include the following items, at a minimum: Description of Mining Activities The plan shall provide a narrative description of the mining and associated activities that took place at the site which affect or may affect stormwater runoff intended to be covered by this permit. The narrative description shall report the approximate dates of operation, the total acreage within the mine site and an estimate of the number of acres of disturbed area. A general description of the location of the mining site relative to major transportation routes and communities shall also be provided.
