COLORADO DEPARTMENT OF PUBLIC HEALTH & ENVIRONMENT - Water Quality Control Division <br />Rationale - Page 7 Permit No. COR-040000 <br />V. TERMS AND CONDITIONS OF PERMIT • <br />B. StormwaterManaaement Plan (SWMP) Requirements <br />The purpose of a SWMP is to identify possible pollutant.sources to stormwater and to set out best management practices (BMPs) <br />that, when implemented, will reduce or eliminate any possible water quality impacts. SWMPs shall include BMPs that are <br />selected, installed, implemented and maintained in accordance with good engineering practices to minimize pollutants in the <br />discharge so that the discharge will not cause or contribute to an excursion above any applicable water quality standard. (The <br />plan need not be completed by a registered engineer.) The Division has a guidance document available on preparing a SWMP. <br />The document is on the Division's website at www.cdphe state.co.us/wy/Permits Unit. <br />The plan identifies potential sources of pollution (including sediment) which may reasonably be expected to affect the quality of <br />stormwater discharges associated with mining or remediation operations. In addition, the plan describes practices which will be <br />used to reduce the pollutants in stormwater discharges from the mining or remediation operation, and to assure compliance with <br />the terms and conditions of this permit. Facilities must implement the provisions of their SWMP as a condition of this permit. <br />The SWMP requirements have been amended in this permit. See Section L.4.5 of the Rationale for a discussion of the changes. <br />Note that some permittees will need to amend their plan to comply with the additional requirements for the SWMP site map, <br />SUMP administrator, and some pollution prevention measures <br />Submittal of the SOW is not automatically required under this permit: However, the Division may require submittal upon <br />request, and review the SWMP and require additional measures to prevent and control pollution. It is the Division's intent to <br />request submission of such reports on a selective basis to determine compliance. See Part I.B. of the permit for a more detailed <br />description of SWMP requirements for active mines and Part LC of the permit for inactive mines and remediation projects. <br />1. SWMP For Active Mining Operations - Contents • <br />a. Description of mining activities <br />b. Area subject to effluent limitations guidelines <br />c. Site map <br />d. Stormwater management controls <br />1) SWMP Administrator <br />2) Identification of potential pollutant sources and BMPs <br />3) Preventive maintenance <br />4) Good housekeeping <br />S) Spill prevention and response procedures <br />6) Employee education <br />7) Identification of discharges other than stormwater <br />e. Comprehensive inspection <br />2. SWMP For Inactive Wining-0B Contents <br />erations - a. Description of mining activities <br />b. Site map <br />c. Stormwater management controls - Identification of potential pollutant sources and BMPs <br />1) SWMP Administrator <br />2) Identification of potential pollutant sources and BMPs <br />d. Comprehensive inspection <br />Inactive mining sites that have non-mining activity occurring (such as remediation) must also evaluate the other potential <br />sources listed in Part LB.4.b, and must include in their SWMP the items listed in Parts LB-4.c, d, e, f and g, as applicable. <br />(6
