Setbacks between each of the mining areas and the property boundary have been maintained to protect the <br />integrity of the adjoining land. The sand and gravel mining process unit be conducted using loaders. and/or <br />excavators. Blasting of the resource is not necessary. Haul trucks, or loaders and conveyors will transport the <br />resource to the nearby crushing and screening area, or the ultimate delivery sde. The crushed and screened <br />material will then be loaded, Vansported and stockpiled in the staging area whoro R will be used in asphalt and <br />concrete production, or hauled to a construction site for use. Each phase includes a layer of sand and gravel <br />up to 25 lest thick. Gravel exUac6on occurs in approximately 20 foot lifts until the undertying bedrock stratum <br />has beon reached. <br />CRUSHING AND STOCKPILE AREAS -The excavated gravel resource is crushed arxf stockpAed according to <br />size near tho mining area. Maximum processing Is approximately 4,000 tons per day. Since a portable cnrsher <br />a used, the location of the crushing operation changes as the mining proceeds across each of the miring <br />areas Used asphalt pavement and concrete rubble is also stockpiled within the staging area for future crushing <br />and/or during [he reclamaton process. Once the asphalt and concrete is crushed to its proper size, it rs <br />stockpiled for use as a recycled material in new construction. Occasionally, sdl that has been determined to be <br />Tree of debris and inert may be brought to the sfte and stockpiled for use in construction related acthntles or, for <br />the reclamation eNorts. <br />por7able and will be relocated as minir <br />eNorts proceed across the various phases. <br />Portable asphalt plant currently located near the <br />southwest comer o/Phase 1. <br />ASPHALT PRODUCTION • A portable asphalt plant may be erected on the site from time to tlme. Material <br />crushed on sRe is used for asphalt production. Maximum production for the portable plant 5 up to 4000 tons <br />per day. Asphalt production is seasonal and nonnalty occurs between April and October The plantwnll meet or <br />exceed all State and Federal pollution requirements, and rs inspected on a regular basis by corporate and <br />governmental authorities. Components associated with the asphalt plant include: Ipuid asphalt storage. <br />aggregate feed bins. mixer, conveyors, lime silo, truck loading equipment, power supply and distribution. <br />From dme to tlme a paving project requires special and unique asphalt mix. When this occurs, a second <br />portable esphaft plant may be erected on the site. Some paving protects may require paving during night time <br />hours. Area lightlng will utilize portable. low-lovel "light plants' These speaal projects generally last 90 to 120 <br />days. <br />CONCRETE PRODUCTION - A concrete batch plant has been erected within the staging area. The plant <br />operated year round and can reach pock production rates of 200 cut>tc yards per hour Apparatus associated <br />with the plant include: cement storage with a dust collection system. water storage, and feed bins with a <br />conveyor system. An equipment repair building is located adjacent to the plant site. <br />
