PRODUCTION PHASE <br /> The production phase of the proposed action consists of the activities necessary to remove <br /> gravel, prepare and stockpile the mined material, and then remove the material from the site(See <br /> Figure 2.3. at the end of this report). This would include the following activities: <br /> 1. A large bulldozer would be used to push gravel down from the top of the existing <br /> cut slopes. The gravel will spill down the existing steep cut slope onto the flat area <br /> at the toe of the slope. Mining will progress from the northern boundary of the <br /> site to the south. <br /> r <br /> { <br /> 2. A front-end loader would be used to move the gravel to a stockpile, a screening <br /> plant, or directly to a truck for removal from the site. <br /> 3. A portion of the mined material would need to be screened to separate large rocks <br /> and insure the consistency of the material. The screening plant would consist of a <br /> two-deck screen with a grizzly on tip. A grizzly is a metal grid placed over the <br /> hopper on the plant and used to separate the largest stones before they enter the <br /> screening plant. A modern screening plant with the necessary safety and dust <br /> control features would be used. Water for dust control would be trucked from a <br /> central water system located in Divide. <br /> 1 4. If the materials removed from the site are too hard or too big to be screened, it <br /> may be necessary to use a crusher. <br /> . 5. Gravel would be removed from the site in 14 to 25 ton( approximately 9 to 17 <br /> cubic yard capacity dump trucks. Assuming an average production rate of up to <br /> 100,000 tons per year, there would be an average of 22 trucks per day. The <br /> intensity of operations would be seasonal with larger production rates taking place <br /> during the summer construction season and scaled back operations during the <br /> winter, depending upon weather conditions. <br /> 6. The quarry would operate between the hours of 7;00 a.m. to 4:00 p.m., Monday <br /> thru Friday. It is anticipated that an average of two full-time employees would be <br /> required to operate the site, with one or two additional employees occasionally <br /> required for peak production periods associated with special projects. <br /> prodphse.00 <br />
