<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
<br /> Safety and Health Admiration (MSHA) ground control plan. Additional details related to slope
<br /> stability can be found in Exhibit 6.5.
<br /> (b) Detailed Earthmoving Operations
<br /> Phase I-Mining
<br /> During Phase I, mining will begin in the pit outlined on Figure C-4. Prior to mining, the access
<br /> road will be constructed and a temporary, portable plant installed in the pit area. In conjunction
<br /> with contemporaneous reclamation, as further described below, the affected area will be
<br /> increased as mining progresses to avoid having large areas of disturbance prior to mining activity
<br /> commencing. Prior to disturbance, all available topsoil will be removed and stockpiled in TS1,
<br /> TS2, and TS3 or in piles along the access road. The topsoil stockpiles will be seeded to prevent
<br /> erosion; this change in cover will prevent accidental disturbance of the stockpiles by the mining
<br /> operation. Rock or concrete barriers will also be placed near the toe of the stockpiles to further
<br /> prevent disturbance to the topsoil stockpiles. Signage will be placed on the topsoil stockpiles
<br /> indicating that they should not be disturbed.
<br /> Mining will begin on the east side of the Quarry area and will progress north and west to establish
<br /> the plant/facilities area. After the topsoil has been removed and stockpiled, drilling and blasting
<br /> will begin at the top of the Quarry and proceed downward in benches to remove the competent
<br /> granite and diabase. Overburden will be removed and hauled to stockpile F1 as shown in Figure
<br /> C-4. The blasted granite and diabase material will be removed with loaders and crushed and
