CRUSHING AND STOCKPILE AREAS - The excavated gravel resource is crushed and stockpiled
<br />according to size within the extraction area. Maximum processing is approximately 3,000 tons
<br />per day. Since a portable crusher is used, the location of the crushing operation changes as the
<br />mining proceeds across the resource area. Crushing apparatus will be operated under the
<br />stipulations contained within the Construction (Air) Permit issued by the Colorado Department
<br />of Public Health and Environment. From time to time used asphalt pavement, concrete rubble
<br />and inert soil may be delivered to the operation from off site sources. Any material delivered to
<br />the facility from outside sources that will be used in the backfilling and grading operations,
<br />Described in Exhibit E, the following procedure will be implemented to insure that the material
<br />is clean and inert:
<br />The individual or company, other than the mine operator, delivering material to the
<br />facility will be required to sign an affidavit certifying that the material is: clean and inert,
<br />the originating source of the material, and the estimated volume. At the discretion of
<br />the facility operator, the certification may also include an environmental audit of the
<br />source site prepared by a Colorado Registered Professional Engineer or a Registered
<br />Environmental Manager.
<br />2. During the stockpiling process, the facility manager and those individuals who operate
<br />the stockpiling equipment will conduct constant visual analysis of the delivered material
<br />on a truck by truck basis. At a minimum, the visual evaluation will identify that the soil
<br />does not have any hydrocarbon contamination, hazardous substances, or other solid
<br />waste.
<br />3. In the event that contaminated material is identified, all work in the immediate area will
<br />cease and a Colorado Registered Professional Engineer or a Registered Environmental
<br />Manager will be contacted by the facility operator. The qualified individual(s) will
<br />prepare, supervise and implement a Remediation and Disposal Plan conducted in
<br />accordance with the requirements of the governing regulatory agencies.
