PARTI Page No. 14 Permit No.: CO-0035776 yi) Consistency with Other Plans SWMPs may reflect requirements for S ill Prevention Control and Countermeasure ((SPCC) plans under section 311 of the CWA, or Best Management Practices ~BMPs) Programs otherwise required by a CDPS penmt, and may incorporate any part of such plans into the SWMP by reference. The SWMP ma reflect information contained in approved plans submitted for other similar ppollution control programs, including the Voluntary Clean Up Program (Voluntary Cleanup and Redevelopment Act, CRS 25-16-303) as long as they contain the elements described above. These plans must have been approved by the implementing agency riot to application for the Stormwater Pemut. Appropriate portions of these other plans maybe incorporated in the SWI~ by reference, as long as a commpplete SWMP can be reproduced and submihed to the regluesting agency witlriri the time frame spec>fied in the request. Those portions of the referenced documents must be inc uded m the submittal. The SWMP must also be readily available to an on-site inspector, b. General Limitations The following limitations shall apply to all discharges authorized by this permit: i) Stotmwater discharges from mining operations or mine-waste remediation projects shall not cause or threaten to cause pollution, contamination or degradation of State waters. ii) Bulk storage structures for petroleum products and other chemicals shall have adequate protection so as to contain all spills and prevent any spilled material from entering State waters. iii) No chemicals are to be added to the discharge unless pemussion for the use of a specific chemical is granted by the Division. In granting the use of such clieaucals, special conditions and monitoring may be addressed by separate letter. iv) All dischazgers must comply with the ]awful requirements of counties, drainage districts and other state or local agencies regazding any dischazges of storrriwater [o storm drain systems or other water courses under their jurisdiction. c.

Unless otherwise provided by the Division, the pemuttee shall have 30 days after such notification to both make the necessary changes to the plan and to miplement them The pennittee shall amend the plan whenever there is a change in design, construction, operation, or maintenance which has a s'¢mficant effect on the•potenhal for the dischazge of pollutants to the waters of the State, or tf the SWMP proves to be ineffective in achieving the general obT7ectives of controlling pollutants in stormwater dischazges associated with mining activity. Amendments to the plan shall be summarized in the Annual Report. d. Prohibition of Non-storrriwafer Discharges i) Except as provided in pazagraph b, below, all dischazges authorized by the stormwater portion of this pernut shall be composed entirely of stormwater.

Revised control measures shall be r' lemented a timely manner, but m no case more than 90 calendaz days after the inspection, unless otherwise provided by the Division. iii) The operator shall keep a record of inspections, including the date of the inspection, major observations relating to the implementation of the SWMP, and actions taken in accordance with paragraph 2), above.
