Document Description
The applicant is proposing to continue mining operations (extraction and processing) at the existing site for a period of 30 years expanding the boundary by approximately one acre to provide sufficient room for final grading activities involved with reclamation. The request does not propose an increase in extraction and processing volumes which are to remain at an average of 3,500 cy per year with a maximum allowance of 8,000 cy per year. Overall, the maximum volumes of material extracted would not exceed 105,000 cy over the 30 year period. Extraction would take place with a bulldozer and front end loader with occasional blasting proposed in areas made up of harder material. Reclamation of the site would occur over three phases moving from the upper north slope of the site towards the south slopes and floor. The proposed and use of the quarry is for cattle grazing consistent with the surrounding ranching operation of the property owner.
