Natural fine material that is generated by the <br />crushing activities will be stockpiled in an area near the overburden stockpiles that can be used <br />as a growth medium during the reclamation efforts described in Exhibit E. Maximum <br />processing is approximately 3,000 tons per day. Since a portable crusher is used, the location <br />of the crushing operation changes as the mining proceeds across the resource area. Crushing <br />apparatus will be operated under the stipulations contained within the Construction (Air) Permit <br />issued by the Colorado Department of Public Health and Environment. From time to time used <br />asphalt pavement, concrete rubble and inert soil may be delivered to the operation from off site <br />sources. Any material delivered to the facility from outside sources that will be used in the <br />backfilling and grading operations, Described in Exhibit E, the following procedure will be <br />implemented to insure that the material is clean and inert: <br />Rev. 02/25/10 3 <br />
