COLORADO DEPART)NENT OF PUBLIC HEALTH & ENVIRONMENT -Water Quality Comrol Division <br />Rationale -Page 6 Permit No. COR-040000 ~ <br />VI. 1ERtY,'S AND' COND/TIONS OF PERMIT <br />A. Prohibition on Nort-stormwater Discharges ' <br />The list of allowable non-slormwater discharges has been increased to include uncontaminated compressor <br />condensate, irrigation drainage, lawn watering, and air conditioner condensate.- These have been determined to be <br />i,uignificant sources of water pollution, and do not need to be covered under an individual discharge permit. <br />- V <br />B. 5'tormwoter Management Plan (SWMP) Reurrements ~ <br />The purpose aja SWMP is to identify possible pollutant sources to stormwarer and to set out best management <br />practices that, when implemented, will reduce or eliminate any possible water quality impacts. A SWMP shall be <br />developed and implemented for each site covered by this permit. 7He SWMP must be prepared in accordance with <br />good engineering practices. (TTte plan need not be completed by a registered engineer.) The Division has a <br />guidance document available ors preparing a SWMP. <br />T7te plan idemtfies potential sources of pollution (including sediment) which may reasonably be expected to affetr <br />the quality of stormwater discharges associated with mining or remediation operations. In addition, the pion <br />describes practice which will be used to reduce the pollutants in stormwarer discharges from the mining or <br />remediation operation, and to assure compliance with the terms and conditions of this permit. Facilities must <br />imp[emeru the provisions of their SWMP as a conditiors of this permit. <br />i <br />The SWAfP requiremems have bee amended in this permit to eliminate redundancies in past requirements. The <br />host notable changes combine the Description of Potential Pollutant Sources/Materials, Risk Identification and <br />Assessmem, and Bcst Management Prarlices sections of the previous SWMP requirements. Rgfer to the Permit, <br />Parts LB. and LC for a complete description of the current SWMP requirements. • <br />Nolc: SWMPs that were prepared in accordance with requirements in the previous pertnil need not be <br />amended to conform to thin format. T&e format is new in this permit, but the essence of the <br />requirements remains the same. <br />Submittal of the SWMP is not automatically required under this permit. However, the Division may require <br />submittal upon request, and review the SWMP and require additional measures ro prevent and control pollution. It <br />is the Division's intent to request submission of such reports on a selective basis. See Part I.B. of the permit for a <br />more detailed description of SWMP requirements for active mines and Part f.C of the permit for inactive mines and <br />remediation projects. <br />SWMP For Active Mining Operations -Contents <br />a.
