boundary. The mesa face in the buffer area will remain undisturbed during mining. <br /> Mining will begin in Phase 1 on the mesa in the southwest portion of the permit area. <br /> Of the approximately 600 acres in Phase 1 over 400 acres will remain undisturbed. <br /> Please refer to the table of Total Disturbance Acres by Phase for the anticipated <br /> affected acres per phase. <br /> The active mining area will be limited to 25 acres at any one time. <br /> Reclamation will occur concurrently with mining. As mining progresses into a new 25 <br /> acre area, the mined out 25 acres will be sloped and contoured in preparation for <br /> final reclamation. This rotational progression of mining and reclaiming will continue <br /> across the mesa and will be consistent throughout the life of the mine. <br /> Earthmoving equipment will vary with mine development. Depending on <br /> depth of plant growth material and overburden, bulldozers and/or scrapers will be <br /> used to expose the target reserve. Loaders will extract the gravel reserve and feed <br /> the processing plant. Bulldozers will maintain slopes and manage stockpiles when <br /> necessary. Reclamation will utilize bulldozers and graders to contour slopes and <br /> prepare surfaces for seeding. <br /> Total Disturbance Acres by Phase <br /> Phase I Phase II Phase III Phase IV <br /> Mining Area 78.0 acres 72.0 acres 75.0 acres 82.0 acres <br /> Processing and Stockpile Area 21.0 acres 24.0 acres 39.0 acres Built w/ <br /> Phase III <br /> Other Mining Related 14.5 acres 11.0 acres 30.0 acres 23.5 acres <br /> Disturbance Areas <br /> Internal North Haul Road 11.7 acres 5.3 acres Built w/ Built w/phase I Phase I <br /> Internal Southwest Haul Road 6.5 acres 4.3 acres 0.9 acres Built w/ <br /> Phase 1-III <br /> External North Haul Road 18.9 acres Built w/ Built w/ Built w/ <br /> Phase I Phase [ Phase I <br /> External Southwest Haul Road 27.3 acres Built w/ Built w/ Built w/ <br /> Phase I Phase [ Phase I <br /> Total 177.87 acres 116.62 acres 134.86 acres 105.50 acres <br /> The aggregate processing plant will move as mining progresses through the <br /> phases. The plant will be located out of sight of adjacent neighbors on the east face <br /> of a mesa in Phases I and II. To minimize the potential for fugitive dust, the plant <br /> will be placed near the toe of a mesa out of the path of prevailing westerly winds. <br /> The processing plant will include portable crushers, screens and conveyors and will <br /> operate within the disturbed area. The control van will serve as operation center for <br /> employees. All interior haul roads will be temporary, reclaimed when they are no <br /> longer needed by the operation. <br /> 6 <br /> Revised October 18, 2016 <br />
