L3. PROJECr DESCRIPTION LA bag house will be used on most crushers,dry screens, transfer points, and all plants to control airborne dust and emissions. A bag house is typically a large metal box that contains fabric filter L "bags"to remove dust particles from the air. LPLANT CONSTRUCTION The plant construction will commence once the site preparation and grading of the plant site has been completed. The stationary plant will be constructed in the Phase IX area. The general plant Llayout is depicted in Figure 3-5. The general components of the aggregate plant include: • Primary crushing and screening tower • Surge pile • Three secondary and tertiary crushing and screening towers • Wet side washing and screening tower • Product stockpiles • Drive under product load-out tower • Radial stacker conveyor • Conveyors LAt its highest point,the aggregate plant will be 65 feet tall. LCONSTRUCTION OF ANCILLARY USES READY NIIX CONCRETE PLANT LA ready mix concrete batch plant will be constructed within the Phase IX area to the northwest of the aggregate plant. Figure 3-5 depicts the location of the batch plant.The concrete batch plant, L with an estimated production of 350,000 cubic yards per year, would have an office measuring approximately 500 square feet in size. The major components of the batch plant include: • Cement silos • Aggregate bins • Conveyors • Baghouse • Bermed admixture tank farm • Concrete reclaimer • Concrete lined washout basins L ASPHALT PLANT An asphalt batch plant will be constructed within the Phase D{area to the southwest of the Laggregate plant and south of the ready mix batch plant. Figure 3-5 depicts the location of the asphalt plant. The asphalt plant, with an estimated production of 400,000 tons per year, would be L owned and operated by a tenant of the applicant. The height of the structures and equipment would be approximately 65 feet to 100 feet above ground level. The tallest structure would be the asphalt plant tower, which would stand approximately 100 feet above ground level. The asphalt L plant would have an office approximately 500 square feet in size.
