be approximately l8 inches of clean fill, suitable for reclamation, placed on disturbed slope areas. To <br />the extent possible, the removed cap material will be salvaged and used to cover the disturbed area. if <br />additional material is required, clean fill material from beneath the sediment in the Sediment Removal <br />Area is expected to meet the criteria for covering areas disturbed by sediment storage operations and <br />will be used as needed. <br />B. Revegetation of the disturbed areas will be accomplished by hydroseeding. Seed, fertilizer and mulch <br />will be applied to vegetated areas disturbed by the sediment excavation, hauling and deposition of the <br />sediment. The seed will be perennial rye sown at a rate of 4 pounds per 1000 square feet. Fertilizer <br />will be 12-12-12 analysis and be applied at a rate of 20 pounds per 1000 square feet. <br />4.0 Protection of Eagle Park Reservoir and Other Fresh Waters <br />Following are actions and measures that will be implemented to ensure the protection of the Eagle Park <br />Reservoir and other fresh waters in the vicinity of the work being performed. <br />4.1 Material Spill Prevention <br />A. Haul trucks will be loaded within the limits of the lake bottom to contain potential spillage that may <br />occur during this procedure. <br />B. Leak Proofing Haul Trucks: Articulated haul trucks with and without tailgates are anticipated to be <br />used to haul the sediment, however, the contractor will have the ability to select appropriate <br />equipment for hauling of this material. These types of trucks are watertight and therefore should limit <br />the potential for spillage of sediments during transportation. An example of this type of equipment is <br />a Cat 730 articulated haul truck with a maximum struck capacity of 17.1 cubic yards. <br />4.2 Sediment Containment <br />A. In order to prevent sediment from running into the Tenmile Pond pool and impacting water treatment <br />operations, a containment berm will be constructed of tailing sand adjacent to the East Side Channel <br />and Tenmile pool. The containment berm as laid out is estimated to be 2,800 feet long and 4 feet <br />high. Actual field conditions may dictate that the containment berm be adjusted to accommodate <br />project requirements. <br />4.3 Storm Water Runoff <br />A. The direction of stormwater flow from the area around Robinson Lake is generally to the north- <br />northeast to a valley that carries water towards Eagle Park Reservoir. Most of the stormwater flows <br />associated with this project report to the existing process water collection system in Robinson Lake, <br />Robinson Tailing Pond, and Tenmile Tailing Pond. A short reach of the haul route will require <br />stormwater controls to prevent release of sediments outside the Climax process water collection <br />system. <br />B. Best Management Practices (BMP's) will be implemented to control storm water runoff. These <br />BMPs will consist of the following controls: <br />• Berming and drainage collection in the critical reach of the Haul Route to detain any sediment or <br />sediment laden stormwater runoff. The detention area will be maintained and cleaned out as <br />necessary to prevent the release of any impacted stormwater outside of the Climax process water <br />collection and treatment system. Additional BMP's will be installed, as necessary, and may <br />include silt fence, straw bale checks, wattles, detention ponds, etc. <br />
