Ione Quarry Expansion Project 2021 (Amended Use Permit and Reclamation Plan)

The Ione Quarry Expansion Project involves a significant amendment to the existing Conditional Use Permit and Reclamation Plan for Specialty Granules (Ione) LLC to expand quarry operations in Amador County, California. The project seeks to extend the permit expiration date from 2075 to 2125, increase the total surface disturbance from 56 to 136 acres, deepen the quarry floor from 325 feet above sea level to 280 feet below sea level, and expand on-site overburden stockpiles from 34 to 86 acres with an elevation increase from 350 to 560 feet above sea level. These changes will enable the extraction of approximately 67.8 million cubic yards of meta-andesite over a 100-year operational period, requiring progressive reclamation, new haul roads, staging areas, and comprehensive environmental controls. The lead agency for permitting is Amador County, which oversees compliance under CEQA, the Clean Water Act, state water quality standards, the Sustainable Groundwater Management Act, and local air quality rules including Amador Air District Rule 218 for fugitive dust and NAAQS for particulate matter. Environmental monitoring, including laboratory analysis of soil and water samples at EAMKO Environmental, Inc., must adhere to EPA 200 Series and APHA methods with strict quality control parameters such as spike recovery ranges of 70–130% and reporting thresholds for contaminants. All operations are subject to stringent environmental mitigation measures enforced through regulatory frameworks rather than traditional federal contracting mechanisms. Blasting activities must be conducted exclusively by licensed contractors using approved storage containers, with spill response protocols integrated into SPCC, HMBP, and SWPPP plans. Personnel involved in blasting must be fully certified, and all documentation must be maintained onsite. The project does not involve a federally governed procurement process; no FAR clauses, contract types, pricing structures, evaluation factors, or acquisition data such as TAS codes, WAWF invoicing, or COR designations are applicable. The solicitation number 2021090273 refers to the state environmental review process under CEQA, not a competitive bidding solicitation. The project applicant is Specialty Granules LLC, with Amador County serving as the permitting authority and primary point of contact. No federal funding, appropriations, or socioeconomic set-asides are involved, and the NAICS code 541620 reflects the environmental consulting nature of the permitting
