COLORADO DEPARTMENT OF PUBLIC HEALTH& ENVIRONMENT- Water Quality Control Division Rationale-Page 4 Permit No. COR-040000 IV. STORMWATER DISCHARGES ASSOCIATED WITH MINING OPERATIONS (cont.) 3. Inactive mine sites where, in conformance with the Voluntary Cleanup and Redevelopment Act, (CRS 25-16- 303), mine-waste remediation projects are undertaken. In this case, the SWMP would be prepared, relying in part on information contained in the Voluntary Cleanup Plan. Once the Voluntary Cleanup Plan is approved by the Hazardous Materials and Waste Management Division, the owner, or third party with permission of the owner, would submit the completed permit application. After the permit certification is issued, stormwater discharges from the remediation project would be authorized. Certification under this permit would be terminated when the termination criteria and other conditions listed at Part LF of the permit are met. C. Types of Activities NOT Covered This permit does not authorize stormwater discharges from other types of regulated industrial activities. Other types of regulated industrial activities that require stormwater discharge permits pursuant to different sections of the regulations[5 CCR 1002-61 Section 61.3(2)(e)(ii)(A-B,D-K)j are covered under separate general permits. This permit also does not authorize the discharge of process water or mine drainage. Applications for process water or mine drainage discharge permits can be obtained from the Permits Unit of the Water Quality Control Division at the address listed in Part I.A.3 of the permit. Stormwater which mixes with process water or mine drainage prior to discharge is considered to be process water or mine drainage.
