COLORADO DEPARTMENT OF PUBLIC HEALTHAND ENVIRONMENT, Water Quality Control Division Rationale-Page B, Permit No. CO-0000132 water quality impacts. A SWMP must be maintained for the Sanborn Creek Mine and Elk Creek Mine in accordance with good engineering practices. (The plan need not be completed by a registered engineer.) The Division has a guidance document available on preparing a SWMP. The plan identifies potential sources ofpollution (including sediment) which may reasonably be expected to affect the quality of stormwater discharges associated with mining or remediatian operations. In addition, the plan describes practices which will be used to reduce the pollutants in stormwater discharges from the mining or remediation operation, and to assure compliance with the terms and conditions of this permit. Facilities must implement the provisions ojtheir SWMP as a condition ojthis permit. There are separate sections in this permit addressing SWMP requirements for pollutant sources in active and inactive porlions of the Sanborn Creek Mine and Elk Creek Mine. 1. SWMP For Active Mining Operations-Contents a. Description ofmining activin'es . b. Area subject to effluent limitations guidelines c. Site map d. Stormwater management controls I) SWMP Administrator 2) Identification ofpotential pollutant sources and BMPs 3) Preventive maintenance 4) Good housekeeping S) Spill prevention and response procedures 6) Employee education 7) Identification of discharges other than stormwater e. Comprehensive inspection 2. SWMP For Inactive Mining Operations -Contents a. Description ofmining activities b. Site map c. Stormwater management controls -Identification ofpotential pollutant sources and BMPs I) Stormwater diversion 2) Sediment and erosion prevention d. Comprehensive inspection Additional SWMP Requirements apply ifthe Sanborn Creek Mine and Elk CreekMine seek terminations ofthe stormwaterporton of this permit. In the event that thepermittee wishes to remediate an inactive mine site and terminate permit coverage, prior to remediation act'vit'es, the SWMP must be amended to include the following items, and thepermittee must notify the Division ofthe change in status. e. Additionalltems 1) Documentation of land owner permission (if the permittee is not the owner) 1) Photographs 3) Description of remedial action to be performed 4) Description ojBMPs during remediation activities S) Procedures for disposal of any water stored within mine waste 6) Description ofpermanent BMPs to be used, final site stabilizaton, and ultimate land use SWMP Development. Coordination and Format Some activities required under the SWMP may already be in place. However, the SWMP will require the permittee to coordinate these activities with any necessary new activities in an orderly manner, so that the result is the reduction or elimination ofpollutants reaching state waters from areas not limited by numeric effluent limitations. It is the permittee's responsibility to notify the Colorado Division of Minerals and Gea[ogy (CDMG) of any changes at theirsite resultingfrom the implementation of the SWMP. This notification allows the CDMG to review the SWMP and incorporate any potential revisions which might be needed into the facility's reclamation permit. It is important to verify that the site reclamation permit matches the SWMP. Such information is usually contained in Exhibit G of 110 reclamation permits. The SWMP may rely upon information developed for other similar pollution control programs such as the SPCC (Spill Prevention Control and Countermeasures) plan, Voluntary CZeanup Plan, or the Mined Land Reclamation Gan Revised: 4128/2004
