Present Land Use
Mining and grazing land / A (Exclusive Agriculture) / 8.3/2.4 (Extensive Agriculture - Steep Slope)

Document Description
Approval of a conditional use permit (CUP) for a 38.35-acre surface mining operation and development of a reclamation plan in accordance with the Surface Mining and Reclamation Act (SMARA) of 1975. Request is intended to supersede original surface and reclamation plan approved on May 26, 1988 (CUP 1, Map 95, Resolution 77-88). As proposed, mining operations would disturb 38.35 acres on three parcels totaling approximately 191.5 acres. Material to be mined will continue to be non-mineral clayey to silty shale and employ open pit mining techniques. Although mining will be accomplished in a single phase, reclamation efforts will be initiated at the earliest point in time on those portions of mined lands that will not be subject to further surface disturbance. The mine will operate with a maximum of 4 employees on site at any one time. The project proponent estimates that between 5,000 and 50,000 tons of material will be removed per year and that a total of 1,500,000 tons of material will have been produced over the life of the mine upon its closure in the year 2024. There will be no waste retained on the site or disposed of off site. Maximum depth of excavation will remain at 100 feet. Final reclaimed pit slopes will be at a 2:1 slope. Water from an on-site agricultural well will be utilized to control dust during mining operations.
