<br /> necessary to haul and feed into the processing system at the plant site. Explosives (ammonium
<br /> nitrate/fuel oil -ANFO), and primers/boosters will be stored offsite and provided by the blasting
<br /> contractor.An ANFO/Emulsion blend is expected to provide the optimal blast fragmentation.
<br /> Once blasted, granite and diabase material will be removed with loaders and placed in trucks to
<br /> be hauled to the plant area where it will be crushed and screened to appropriate sizes.
<br /> Contemporaneous reclamation will occur throughout mining as feasible and as areas are
<br /> available. During mining, overburden and fines will be stored in stockpile F1 or used to reclaim
<br /> completed areas. After mining establishes the eastern and western pit floors, overburden and
<br /> fines will be direct hauled and placed as backfill in backfill areas F2 and F3. The overburden and
<br /> fines will first be placed in the F2 area, as shown on Figure C-6. As sufficient pit floor area
<br /> becomes available, the overburden and fines will be placed on the pit floor to augment reclamation
<br /> efforts. During reclamation, fines and overburden will be used as a subgrade material placed
<br /> beneath the topsoil to aid in revegetation. Each phase of mining and reclamation activities are
<br /> discussed in detail below.
<br /> The conceptual locations of in-pit access and haul roads are shown on the figures; however, the
<br /> haul road locations will be based on field observations during the execution of the Plan. Should
<br /> these roads need to be moved, a Technical Revision will be submitted to incorporate new facilities
<br /> showing the location and size(width and length) of each road into the mining area. This Technical
<br /> Revision will include a revised facilities map.
<br /> The acreage, overburden volumes and saleable tons for each phase can be found in Table D-2.

<br /> During initial construction and mining operations the roads, Quarry area, and other affected areas
<br /> will be periodically monitored for rock falls. This plan will be submitted as part of the required Mine
