PROJ-2024-00173 Lynx Cat Mountain Quarry Expansion

The Lynx Cat Mountain Quarry Expansion project, authorized under Conditional Use Permit PROJ-2022-00139 and solicitation number 2081-2025-007-06, seeks to extend mining operations through December 31, 2077, with a phased expansion of the quarry from 48.2 acres to 161.7 acres across two parcels and an additional 80 acres west of the main quarry for crushing, screening, processing, and product stockpiling. The project also involves increasing the mine depth from 250 feet to 500 feet below ground surface, necessitating extensive grading, clearing, and infrastructure development including perimeter fencing and earthen berms. The primary contractor, Matcon Corporation, is required to comply with a comprehensive set of environmental mitigation measures overseen by San Bernardino County and the California Department of Fish and Wildlife, including the implementation of an Incidental Take Permit (ITP No. 2081-2025-007-06) for the protection of desert tortoise and Mohave ground squirrel, enforced through a certified Biological Monitoring Plan and adherence to dust control standards under Mojave Desert Air Quality Management District Rules 402 and 403. Operations must also include archaeological monitoring, use of EPA-approved dust suppressants, and adherence to the approved Mitigated Negative Declaration under CEQA, with compliance verified through on-site inspections and regulatory review at county and state offices. There is no designated contract value, pricing structure, or federal acquisition clauses, as this is an environmental permitting and land use authorization under state law rather than a federal procurement contract; however, the project requires formal submission of environmental documentation and payment of associated state fees, with all activities subject to continuous monitoring and reporting by the applicant. The place of performance is identified as the quarry site in Hinkley, California, within Assessor’s Parcel Numbers 0496-011-75 and 0496-011-76, with oversight provided by Derek Newland of San Bernardino County Land Use Services and Steven Recinos of CDFW.
