Transit Mix Concrete Co. <br /> During Phase II, mining will continue east until reaching the furthermost eastern endwall (as <br /> shown in Figure C-5). Mining will then begin progressing to the south as shown in Figure C-5. <br /> The topsoil removed during Phase II will be temporarily stored in TS1, TS2 and TS3. After the <br /> topsoil has been removed and stockpiled, drilling and blasting will begin at the top of the Quarry <br /> and proceed downward in benches to remove the competent granite and diabase. <br /> Overburden will be removed and hauled to stockpile F1 as shown in Figure C-5. The blasted <br /> granite and diabase material will be removed with loaders and placed in trucks to be hauled to <br /> the plant area where it will be crushed and screened to appropriate size. The transition from the <br /> portable plant to the permanent plant occurs during Phase II. Fines generated from processing <br /> will be hauled to stockpile F1. <br /> During Phase II, the maximum highwall height is elevation 7,240 feet and the minimum pit floor <br /> depth is elevation 6,940 feet for a total pit depth of 300 feet. <br /> Table D-3 illustrates the affected areas during Phase II of mining. <br /> Phase II-Reclamation <br /> Once the eastern-most portion of the pit has reached the ultimate extent, this area will be <br /> reclaimed during Phase II. Overburden and fines generated from mining will be used to backfill <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-3. 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. The blasted granite and diabase <br /> material will be removed with loaders and placed in trucks to be hauled to the plant area where it <br /> will be crushed and screened to appropriate size. Fines generated from the processing will be <br /> hauled to stockpile F1 and F3, until pit floor becomes available. At that point, fines will be placed <br /> 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 /> Hitch Rack Ranch Quarry Permit Application <br /> October 3, 2017 D-9 <br />
