DISCJSSIGN: ion Applicable effluent limitations and monitoring requirements regarding active mining outfalls are addressed in Part I.B.1(a) and I.B.3(a) respectively of the general permit. The effluent limitations and monitoring requirements regarding any applicable postmining activities are addressed in Part I.B.1(b) and I.B.3(b) respectively of the general permit. At this time, based upon a review of the facility conditions, discharge point 001 is still subject to active mining limitations and monitoring requirements. Monitoring of the discharge for Total Dissolved Solids and Total Phosphorus is not required for this permit. See page 3 of the general permit for more information. The Permittee will be required to develop and implement a Storm Water Management Plan (SWMP). Although some activities may already be in place, the SWMP will require the Permittee to coordinate best management practices so the result is a reduction or elimination of pollutants reaching state water from areas not limited by effluent limitations. The Permittee will be required to submit the SWMP to the Division for review within six months from the date certification is issued. For specifics of the Plan and additional requirements, please reference the Part I.B.2 of the general permit. There are neither any landfills nor is there bulk storage of diesel fuel, gasoline, or solvents located adjacent to or near this facility. There is a refuse mine tailings storage area on site, as shown in figure 1 of the permit. Additionally, there are no known drinking water intakes within 5 miles downstream. The permittee will not be required to perform Whole Effluent Toxicity (WET) testing pursuant to Section 6.9.7(2)(a)(i)(A) of the Regulations for the State Discharge Permit System 6.1.0 (S ccr 1002-2) which exempts facilities certified under the general permit. The Permittee is encouraged to read the general rationale for an understanding of how the general. permit was developed and to read the permit itself to see what requirements exist. Effluent limitations and monitoring requirements are specified in Part I.B, and special notification requirements for effluent violations are addressed in Part II.A.3. It should be noted that as of October 1, 1992, the Health Department is moving to a new location, and thus the mailing address has now been changed. Instead of the address indicated on page 13 of the permit, discharge monitoring reports should be sent to the WQCD at the following address: Colorado Department of health Water Quality Control Division WQCD-PE-B2 4300 Cherry Creek Drive South Denver, Colorado 80222-1530 Based on the above information, Energy Fuels Mining Company is certified to discharge from the Raton Creek Mine under the general permit for coal mining facilities, identified as Permit No. COG-850000. All correspondence relative to this facility should reference the specific facility Permit No. COG-850032. Dan Nolmer August 26, 1992
