COLORADO DEPARTM FNT OF PUBLIC HEALTH & ENVIRONMENT - Water Quality Control Division <br />Rationale - Page 5- Permit No. COR-040000 • <br />III. STORMWA TER DISCHARGES ASSOCIATED WITH MINING OPERATIONS <br />Inactive mine sites where, in conformance with the Voluntary Cleanup and Redevelopment Act, (CRS 25-16-303), mine-waste <br />remediation prgjects are undertaken. In this case, the SWMP would be prepared, relying in part on information contained in <br />the Voluntary Cleanup Plan. Once the Voluntary Cleanup Plan is approved by the Hazardous Materials and Waste <br />Management Division, the owner, or third party with permission of the owner, would submit the completed permit application. <br />After the permit certification is issued, stormwater discharges from the remediation project would be authorized. <br />Certification under this permit would be terminated when the termination criteria and other conditions listed at Part IF of the <br />permit are met. <br />C. Types ofActivides NOT Covered <br />This permit does not authorize stormwater discharges from other types of regulated industrial activities. Other types of regulated <br />industrial activities that require stormwater discharge permits pursuant to different sections of the regulations [5 CCR 1002-61 <br />Section 61.3(2)(e)(ii)(A-B, D -K)] are covered under separate general permits. Specifically, clearing, grading and excavation <br />activities that are conducted as part of exploration and construction phases of a mining operation cannot be covered under this <br />permit if these activities will disturb one or more acres of land. Instead, coverage for these activities must be under the CDPS <br />General Permit for Stormwater Water Discharges Associated with Construction Activity: If the area of disturbance during the <br />initial phase is less than one acre, the disturbance is covered under the requirements of this permit, especially those concerning <br />sediment and erosion prevention. <br />This permit also does not authorize the discharge ofprocess water or mine drainage. Applications for process water or mine <br />drainage discharge permits can be obtained from the Permits Section of the Water Quality Control Division at the address listed <br />in Part LA.3 of the permit Stormwater which mixes with process water or mine drainage prior to discharge is considered to be <br />process water or mine drainage. <br />Table 1- Mineral Industry Stormwater Permit Coverage <br />SIC General <br />Code Industry Tyne Permit Note <br />10 Metal Mining and Milling COR-040000 (1) <br />12 Coal Mining COG-850000 (2) <br />13 Oil and Gas Extraction (including Oil shale operations) COR-010000 (3) <br />14 Mining and Quarrying of Sand & Gravel (and other COG-500000 (4) <br /> Nonmetallic Minerals Except Fuels) <br />10,12 Inactive Metal (and Coal) Mines COR-040000 (5) <br />-- Mine-waste Remediation COR-040000 (6) <br />Notes: <br />(1) This permit,, Colorado General Stormwater Discharge Permit for Metal Mining, number COR-040000. <br />(2) Stormwater discharges from coal mines with surface runoff onl are covered by general permit COG-850000. <br />Coverage for stormwater discharges from coal mines with discharge sources which are authorized under <br />individual CDPS permits, is provided by this permit, Colorado General Stormwater Discharge Permit <br />number COR-040000. <br />(3) Stormwater discharges from oil and gas extraction (including oil-shale operations) are covered under the <br />Colorado General Stormwater Discharge Permit for Light Industry, number COR-010000. <br />(4) Stormwater discharges from active and inactive sand, gravel and other non-metallic quarrying and mining <br />operations are covered under Colorado General Stormwater Discharge Permit number COG-500000. <br />(5) Stormwater discharges from inactive metal and coal mines are covered under this permit, Colorado General <br />Stormwater Discharge Permit number COR-040000. <br />(6) Stormwater discharges from mine-waste remediation operations are covered under this permit, Colorado <br />General Stormwater Discharge Permit number COR-040000. l._
