r o Transit Mix Concrete Co. <br /> disturbance to the reclamation areas. Additionally, overburden and fines generated from mining <br /> will be used to backfill area F3. As areas become available, stockpiled topsoil from TS1 and TS4 <br /> will be spread and the area will be seeded with the seed mix provided in Table E-7 and mixed <br /> conifer or mountain shrubland seedlings planted as described in Exhibit E. See Figure C-6 for <br /> the backfill area F2 that will be reclaimed during Phase III. <br /> Phase IV-Mining <br /> During Phase IV, mining will progress south until reaching the furthermost southern endwall (as <br /> shown in Figure C-7). The topsoil removed during Phase IV will be temporarily stored in TS4 or <br /> direct hauled and spread on stockpile F1 as regraded areas/slopes are available. After the topsoil <br /> has been removed and stockpiled, drilling and blasting will begin at the top of the Quarry and <br /> proceed downward in benches to remove the competent granite and diabase. Overburden will be <br /> removed and hauled to stockpile F2 as shown in Figure C-7. 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. <br /> During Phase IV, the maximum highwall height of the pit is elevation 7,530 feet and the minimum <br /> pit floor depth is elevation 6,940 feet for a total pit depth of 590 feet. <br /> Table D-3 illustrates the affected areas during Phase IV of mining. <br /> Phase IV-Reclamation <br /> Slopes on F2 that have been filled to final grade will be reclaimed by placing topsoil, seeding, and <br /> planting mountain shrubland seedlings planted as described in Exhibit E. <br /> Phase V-Mining <br /> Mine progression during Phase V, similar to the phases discussed above, overburden and fines <br /> generated from mining will be used to continue backfilling the pit. These areas are referred to as <br /> backfill areas F2 and F3 and are shown on Figure C-8. As overburden/fines are hauled and <br /> dumped on backfill area F2 and F3, the north and east facing slopes will be regraded to the final <br /> design of 3H:1 V slopes and reclaimed. <br /> Phase V-Reclamation <br /> Similar to the phases discussed above, during Phase V, prior to mining progressing downward in <br /> benches, the final endwall benches will be reclaimed. These activities will include placing at least <br /> one-foot of fines/overburden materials covered with six inches of topsoil as illustrated in Figure <br /> F-2 (inset). The fine/overburden material will either be direct hauled from the active mining area <br /> or hauled from F1 stockpile. Once this is finished, the remaining portion of the F1 stockpile(above <br /> elevation 7,250) will be regraded to the final design of 3H:1 V slopes. A portion of the <br /> fines/overburden material will be hauled and placed on the western endwall and in the pit to assist <br /> Hitch Rack Ranch Quarry Permit Application <br /> March 20, 2018 D-11 <br />
