Mining will progress through the Phases numerically. A table of expected mining lives for each
Phase is included in Table D -2. The life of each Phase is based on the anticipated annual
maximum tonnage. Any available topsoil from a new area will be used to reclaim the previously
mined areas. This will reduce material moving as well as reduce the maximum area to be
reclaimed. Since there is not sufficient topsoil on site to reclaim the site, some screening fines will
be salvaged and tested to determine necessary additives to make the fines suitable for reclamation
topsoil.
The pit will be isolated from surrounding run -off by a berm along the highwall during mining.
Also, a catch berm will placed along the road on the south side of the pit to prevent stormwater
from leaving the pit. Stormwater run -off calculations are shown in Exhibit G.

Note that the areas above only include mining areas, not areas along the perimeter. The anticipated
total mining area for the operation consists of approximately 24.9 acres. The total disturbed area
will be 38.1 acres.
Highway trucks will haul material for sale to market from the processing site. Truck traffic will
utilize County Lane 15.
The gravel thickness is approximately 20 feet, and it is believed that the deposit is relatively flat.
