Transit Mix Concrete Co. <br /> the benches, which will be reclaimed by placing six inches of topsoil on the graded surface and <br /> seeded with the seed mix provided in Table E-7. Mixed conifer or mountain shrubland seedlings <br /> will be planted as described in Exhibit E. <br /> Phase III-Mining <br /> During Phase III, mining will progress from the plant/facilities area to the west until reaching the <br /> furthermost western endwall (as shown in Figure C-6). The topsoil removed during Phase III will <br /> be temporarily stored in TS4 or direct hauled and spread on the north and east facing slopes of <br /> fines stockpiles F1, F2, and F3 as illustrated in Figure C-6. After the topsoil has been removed <br /> and stockpiled, drilling and blasting will begin at the top of the Quarry and proceed downward in <br /> benches to remove the competent granite and diabase. Overburden will be removed and hauled <br /> to stockpile F1, and as pit floor becomes available to F2 as shown in Figure C-6. Fines will be <br /> placed in stockpile F3 before topsoil is placed in TS4 on top of F3. Fines stockpile F3 will be <br /> graded flat before placing the topsoil stockpile. Any additional fines placed in F3 would be at the <br /> toe area to keep the fines and topsoil materials separated. Cross-sections of the fines stockpiles <br /> including details on extent of mining, operational surface, and reclamation surface are included in <br /> Figures C-9b and C-9c. The blasted granite and diabase material will be removed with loaders <br /> and placed in trucks to be hauled to the plant area where it will be crushed and screened to <br /> appropriate size. Fines generated from the processing will be hauled to stockpile F1 and F3, until <br /> pit floor becomes available. At that point, fines will be placed in stockpile F2. <br /> During Phase III, stockpile F1, the Fines/Overburden stockpile, will be filled to design capacity. <br /> During Phase III, the maximum highwall height is elevation 7,420 feet and the minimum pit floor <br /> depth is elevation 6,940 feet for a total pit depth of 480 feet. <br /> Table D-3 illustrates the affected areas during Phase III of mining. <br /> Phase III-Reclamation <br /> During Phase III the lower portion of F1 stockpile, below elevation 7,250 will be regraded to the <br /> final reclamation surface at 3H:1 V slopes. These activities will include placing six inches of topsoil <br /> on the regraded surface. The topsoil material will be spread from TS2 onto the regraded slope or <br /> hauled directly from newly affected areas. <br /> Overburden and fines generated from mining will be used to backfill the pit. This area is referred <br /> to as backfill area F2 and is shown on Figure C-6. As overburden/fines are hauled and dumped <br /> on backfill area F2, the north and east facing slopes will be regraded to the final design of 3H:1V <br /> slopes and reclaimed. The F2 stockpile material will be end dumped or placed in lifts as the <br /> stockpile expands southwards. No new material will be placed on the north-facing slopes that <br /> have been reclaimed, and the northern and eastern portions of the F2 backfill area will not be <br /> affected by the expansion of the F2 backfill area.
