Identification of Discharges other than Stormwater -The stormwater cotn+eyance 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 stormarater, the method used, the date of any evaluations and the on-site drainage points that were directly observed doting the evaluation. A number of discharges other than stomtwater may not require a CDPS Wastewater Discharge permit and are considered Allowable Nan-stormwater Discharges. These are listed at Part I.D.3, below. Any of these discharges that e~rist at the site ttnrst be identified in the SWMP. 5. Comarehenslve Iasoection The SWtuIP shall identify qualified persoffiel that shalt inspect designated equipment and mine areas at appropriate intervals specified is 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 sumnmrized in the AHnusl Report (see Part I.E.I.a of the permit). 6.

The SWIu1P may rely upon information developed for other similar polhrtion cotttml pro8tams, including the Miaod Lam Reclamation Plan. Appropriate portions of these other pleas maybe incorporated in the SWI4II' by reference, as long as a complete SWMP can be reproduced and submitted to the requesting agency within the time frame specified is the request.

STORMWATER MANAGEMENT PLAN -INACTIVE MINES A Stormarater Management Plan (SWIM') shall be developed fm each inactive mine covered by this permit. The SWMP shall include best management practices (BMPs) that are selected, iststdled, implemented and maintained in accordamx with good engineering practices. (T'he plan need not be completed by a registered engineer.) The plan shall identify potential sources of pollution (inchtding sediment) which may reasonably be expected m affect the quality of sourmrvater discharges associated with the inactive mining operation. In addition, the plea shall desctybe and ensrue the implementation of BMPs which will be used to reduce the polhrtants in storrmarater discharges associated with the inactive mining operation and to assure compliance widt the temps snd conditions of this permit. Inactive mining operations mmst implement the provisions of their SWMP as a condition of this pertdt. The Division reserves the right to review the plan, anti m require additional measures to preve~ and control pollution as Headed. Any SWMP prepared before September 30, 20Q6 that does not meet all of the regnirementa listed herds (especially those items regnired for the site map) must be anxnded to conform with the 5WMP requtrementa h3 this permit. Such ~ must be eornpleted within 60 days of the certification effective date (which is typically October 1, 2006). The SWiVIP shall inchtde the following items, at s miniaaran: 1. Descrin~on of Mining Activity T1se plan shall provide a narrative description of the mining and associated activities that took place at the site which affect or rosy affect stormarater runoff intended m be covered by this permit. The narrative description shall report the approximate dates of operation, the total acreage within the mitre site and an estimate of the cumber of acres of disdubed area A general description of the locatiarz of fire mining site relative to major transportation mutes and eazaaruaities shall also be provided.
