boundary. The mesa face in the buffer area will remain undisturbed during mining. Mining will begin in Phase 1 on the mesa in the southwest portion of the permit area. Of the approximately 600 acres in Phase 1 over 400 acres will remain undisturbed. Please refer to the table of Total Disturbance Acres by Phase for the anticipated affected acres per phase. The active mining area will be limited to 25 acres at any one time. Reclamation will occur concurrently with mining. As mining progresses into a new 25 acre area, the mined out 25 acres will be sloped and contoured in preparation for final reclamation. This rotational progression of mining and reclaiming will continue across the mesa and will be consistent throughout the life of the mine. Earthmoving equipment will vary with mine development. Depending on depth of plant growth material and overburden, bulldozers and/or scrapers will be used to expose the target reserve. Loaders will extract the gravel reserve and feed the processing plant. Bulldozers will maintain slopes and manage stockpiles when necessary. Reclamation will utilize bulldozers and graders to contour slopes and prepare surfaces for seeding.

The plant will be located out of sight of adjacent neighbors on the east face of a mesa in Phases I and II. To minimize the potential for fugitive dust, the plant will be placed near the toe of a mesa out of the path of prevailing westerly winds. The processing plant will include portable crushers, screens and conveyors and will operate within the disturbed area. The control van will serve as operation center for employees. All interior haul roads will be temporary, reclaimed when they are no longer needed by the operation. 6 Revised October 18, 2016
