Skyline Mine, TLT Enterprises (UP #2023-010, RP #2023-001, EIR #2023-004)

The proposed project at the Skyline Aggregates site would include mining, processing, and reclamation activities by Hat Creek Construction and Materials, Inc. on approximately 460 acres of a 640-acre parcel. Materials mined onsite will consist of hard rock aggregate. Aggregate mined on the site will be crushed, screened, washed, and graded onsite and then used in the production of virgin aggregates, asphalt mix, and ready-mix concrete. Equipment onsite will include loaders, generators, a concrete batch plant, concrete trucks, service truck, man lift, belly dump, articulated dump truck, crusher, and asphalt batch plant. Wet suppression will be used when necessary to control dust caused by excavation, processing activities, and materials transport. Backup generators will be available onsite. The site will be mined in five phases, taking approximately 10 years per phase and 50 years total to complete. Mining operations are estimated to begin in the spring of 2027, following permit approval. The termination date will be based on demand.
