PART 11 Page No. 13 Permit No. COG-500000 6. SWMP Administrative Requirements a. SWMP Preparation and Implementation: The SWMP shall be prepared prior to applying for coverage under the general permit, and certification of completion submitted with the application. The SWMP shall be implemented when the facility begins operation, or when the general permit certification is issued, whichever is later, and updated as appropriate (see paragraph c., below). b. SWMP Retention: For active mining operations and sites undergoing reclamation, the plan shall be retained on site unless another location, specified by the permittee, is approved by the Division. For inactive mining operations, the plan shall be retained by the permittee. C. SWMP Review/Changes: 1) Division Review: The Division reserves the right to request and review the SWMP, and to require additional measures to prevent and control pollution, as needed. Upon review of the SWMP, the Division may notify the permittee at any time that the plan does not meet one or more of the minimum requirements of this permit. After such notification, the permittee shall make changes to the plan and shall submit to the Division an update to the plan.including the requested changes. Unless otherwise provided by the Division, the permittee shall have 30 days after such notification to both make the necessary changes to the plan and to implement them. 2) Permittee Review/Change: The permittee shall amend the plan whenever there is a change in design, construction, operation, or maintenance which has a significant effect on the potential for the discharge of pollutants to the waters of the State, or if the SWMP proves to be ineffective in achieving the general objectives of controlling pollutants in stormwater discharges associated with mining activity. If existing BMPs need to be modified or if additional BMPs are necessary, the plan changes and implementation should be completed before the next anticipated storm, but in no case more than 60 days aften the change in design, construction, operation, or maintenance, or, when the SWMP has been determined to be ineffective. Amendments to the plan shall be summarized in the Annual Report. It is the permittee's responsibility to notify the Colorado Division of Minerals and Geology (formerly the Mined Land Reclamation Division) of any significant changes at their site resulting from the implementation of the SWMP. 7. Prohibition of Non-Stormwater Discharges a. Except as provided in paragraph b, below, all discharges authorized by Part I.C. of the permit shall be composed entirely of stormwater. Discharges of material other than stormwater must be addressed in Part I.B. or in a separate CDPS permit issued for that discharge. b. Discharges from the following sources that are combined with stormwater discharges associated with mining activity may be authorized by this permit, provided that the non-stormwater component of the discharge is identified in the SWMP (see Part I.C.2.c.4 of the permit): emergency fire fighting activities, uncontaminated compressor condensate, irrigation drainage, lawn watering, air conditioner condensate, uncontaminated seeps and springs, and foundation or footing drains where flows are not contaminated. 8. Employee Education The permittee shall develop and implement employee education programs to inform personnel at qll levels of responsibility of the components and goals of the SWMP. Education shall address topics such as spill response, good housekeeping, and material management practices. The permittee 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. 9. Total Maximum Daily Load (TMDL) If a TMDL has been approved for any waterbody into which the permittee discharges, and it has been determined that the types of stormwater discharges covered under this permit are or have the potential to be identified as a significant source of the pollutant in question, the permittee will be notified by the Division. The permittee will be required to do the following: a) under the permittee's SWMP, implement specific management practices based on requirements of the TMDL, and evaluate whether the requirements are being met through implementation of existing stormwater BMPs or ifadditional BMPs are necessary. Document the calculations or other evidence that show that the requirements, including any
