The Stormwater Management Plan(SWMP)format is based on the Colorado Discharge Permit System <br /> (CDPS)General Permit for Sand and Gravel Mining and Processing(Permit No.COG-500000)(General <br /> Permit). <br /> The SWMP identifies potential sources of pollution(including sediment)reasonably expected to affect <br /> the quality of stormwater discharges associated with the mining activity. In addition,the SWMP <br /> describes practices to be used to reduce pollutants in stormwater discharges associated with mining <br /> activity at the facility,and ensure those practices are selected and described in accordance with good <br /> engineering practices(including the requirements for installation,implementation,and maintenance). <br /> Also,the SWMP is prepared and updated in accordance with the"Stormwater Management Plan <br /> (SWMP)"section of the"Stormwater Discharges"section of the General Permit,to ensure compliance <br /> with the terms and conditions of the General Permit. <br /> As a condition of the General Permit, facilities must implement the provisions of the SWMP as written <br /> and updated, from commencement of facility activity until completion of final reclamation. <br /> This SWMP includes and identifies the following: <br /> • A facility description and map <br /> • One or more individuals(with specification of position[s] or title[s] within the mining <br /> organization)responsible for developing,implementing, maintaining,and revising the SWMP <br /> • Potential pollutants at the facility, and materials and business practices at the facility that may <br /> lead to discharges of polluted stormwater <br /> • Best Management Practices(BMP)that will be used to prevent potential discharges <br /> • Other pollution prevention measures <br /> • A preventive maintenance program that incorporates the requirements for inspection frequency <br /> and monitoring <br /> • Good housekeeping practices <br /> • All discharges other than stormwater. <br /> Three Bells Pit Stormwater Management Plan i 12/2013 <br />
