Stormwater runoff will flow across the site toward the excavated areas or the sediment pond within the <br /> processing area that will act as settling basins for suspended solids. The excavations will retain runoff <br /> from small storm events on-site. <br /> Some channelization may need to be added during future mining phases in order to continue collecting <br /> all runoff in the mining excavations. The stormwater conveyance improvements will be described in <br /> future annual SWMP reports if they are constructed. <br /> This site is located in the floodplain of the Cache La Poudre River. Problems associated with sediment <br /> transport through the floodplain are expected to be minor. Flood elevations in this area are not expected <br /> to be impacted by this operation. The excavation of a pit will reduce the floodplain width as well as <br /> flow velocities. It will act as a sediment trap and reduce the amount of sediment potentially leaving the <br /> site. <br /> Equipment used for the extraction and hauling of the aggregate will be stored on-site, near the <br /> processing area. Daily equipment monitoring will occur on-site. Maintenance repair activities will be <br /> performed off-site. Occasionally, a mobile service truck may be brought on site to perform oil changes. <br /> 3.0 Potential Pollutant Sources/Material Inventory <br /> Potential pollutants expected to be stored on-site would include but not be limited to, diesel fuel and <br /> small amounts of miscellaneous equipment fluids and oils. There will be one diesel fuel tank with the <br /> total capacity for 10,000 gallons of fuel. <br /> One parking area for both employee vehicles and the mining equipment will be located near the <br /> processing area. This area will be gravel. <br /> Haul routes within the site will be gravel or dirt, depending on their location, and can be expected to be a <br /> source of potential pollution to stormwater runoff. The access road into the site will be gravel for a <br /> minimum of 125 feet. <br /> No spills of significant quantities of any substance are known to exist at this site. <br /> 4.0 Best Management Practices (BMPs) for Stormwater Pollution Prevention <br /> 4.1 SWMP Administrator <br /> Dave Simpson, Vice President, Connell Resources, Inc., will be the SWMP Administrator. The <br /> Administrator will be responsible for handling the day to day management of the SWMP at the site. The <br /> SWMP Administrator may appoint other personnel to assist him as needed. A SWMP team may be <br /> created to share the responsibility and generate greater awareness and participation. Any and all changes <br /> to the SWMP will be noted directly on the report or the maps for incorporation into the plan. <br /> 2 <br />
