through 5C. Each conveyor crossing will be enclosed in 100-foot spans, approximately 17 feet in height over the county roads. A conveyor will also cross the Cache La Poudre River. The conveyor bridges are composed of steel; the footings are anchored in concrete. Details for the conveyor bridges can be found in Exhibit C. Upon completion of mining operations, the conveyors will be removed and all areas affected by the conveyors will be restored to their original condition. There is also the potential for a conveyor tunnel to be constructed under "O" Street if "O" Street is constructed prior to the completion of mining of Phase 5C. All existing on-site roads are shown on Exhibit C, Pre-Mining Plan. Any existing gravel access roads shared with ongoing oil and gas production or farming activities will remain in place once mining and reclamation are complete. The roads will be maintained by the operator to provide required access to the various activities on the property. Existing roads are typically 12' to 15' wide, gravel access lanes. Some of the roads may be relocated to accommodate mining activities. Relocated access lanes will be constructed with 6" of native sand and gravel from the floor of the mine and remain in place once mining and reclamation are complete. The main access to the site will be off of County Road 25 on the west side of Phase IA. There will be a paved loop lane into the site as shown and dimensioned on page 4 of Exhibit C. Mine Schedule The Parsons Mine operation will process approximately 750,000 - 1,000,000 tons of aggregate per year. At this rate, Lafarge anticipates mining and reclaiming the site in approximately 20 years; however, the rate of mining and overall life of the mine is dependent upon demand and market conditions. The mine phases are depicted in Exhibit C. The phases depicted in Exhibit C are used to indicate the direction of mining. These phases are neither representative of the maximum area of disturbance nor do they limit disturbance to a particular phase. Phase Overview Phase IA will be stripped of overburden to the sand and gravel layer below. The processing plant will be set up at this elevation. Phase IA will also be the location of the fresh water pond (approximately 5 acres) and temporary silt storage pond (approximately 2 acres) until the permanent silt storage ponds (in Phases 1 B and 1 C) are completed. Phase 1 A will actually be mined last as the ,processing plant will be used through the mining of Phase 5C. Phases 1 B and 1 C will be the first Phases to be mined as they will be the location of the silt storage ponds needed for the duration of the mine. Due to the location of an active Bald Eagle's nest within '%4 mile of a portion of Phase 1 C and within '/z mile of a portion of Phase 1 C and all of Phase 1 B, mining will be restricted per discussions with the Colorado Division of Wildlife and US Fish and Wildlife, as outlined in Exhibit H in the section titled "General Effect on Wildlife Due to Mining Operations." Phase 2 will then be mined followed by Phase 3 and so on until Phase 5C and then Lafarge will return to mine Phase IA. Each Phase will be reclaimed following mining.
