Mining will occur in five distinct phases that are illustrated on Sheet 2 in Exhibit C. That
maximum disturbed area, not including prior reclaimed areas, is anticipated to be 10 acres. A
summary of each mining and reclamation activates on a phase by phase basis is presented on
the following tables:

CRUSHING AND STOCKPILE AREAS - The excavated gravel resource is crushed and stockpiled
according to size within the extraction area. Natural fine material that is generated by the
crushing activities will be stockpiled in an area near the overburden stockpiles that can be used
as a growth medium during the reclamation efforts described in Exhibit E. Maximum
processing is approximately 3,000 tons per day. Since a portable crusher is used, the location
of the crushing operation changes as the mining proceeds across the resource area. Crushing
apparatus will be operated under the stipulations contained within the Construction (Air) Permit
