Mine/Quarry; Mine ID 91-03-0011 Specialty Granules (Ione) LLC (SGI) operates Ione Quarry, an approximately 330-acre hard rock mining operation within an unincorporated area of AmadorCounty (County), approximately three miles west of the city of Ione. SGI has been continuously mining for hardrock at the Ione Quarry (project site) since the site was permitted for mining, processing, and offsite shipment in 1989.
Document Description
The applicant, Specialty Granules (Ione), LLC (SGI) proposes to expand the existing footprint and depth of Ione Quarry to access additional rock reserves. This expansion requires an amended Conditional Use Permit (CUP) and an amended Reclamation Plan that allows for the expanded proposed mining area and additional stockpiling area(s) for the additional cap rock (the proposed project ). The project does not propose an increase in the current rates of production at the quarry or changes to other operations. After the expansion, the quarry's total surface disturbance would have increased from approximately 56 acres to approximately 136 acres and the depth would b approximately 280 ft. below mean sea level [MSL], compared to 325 MSL under the existing conditions. The stockpile area's total surface disturbance would be approximately 86 acres and have a maximum elevation of 560 MSL.
