Operations in this class involve developing quarry sites and extracting crushed and broken stone — including marble, sandstone, bituminous limestone, and bituminous sandstone — through drilling, blasting, and mechanical crushing. Beneficiating plants on-site may grind, screen, wash, or pulverize stone for commercial sale. Heavy mobile equipment typically operates continuously during production shifts, and finished aggregate is often staged on-site for trucked delivery to construction, infrastructure, and industrial buyers.
Questions to investigate
- Is blasting performed on-site, and if so, how frequently and by whom — the insured's own crew or a licensed blasting contractor?
- What is the proximity of the quarry boundary to occupied structures, public roads, or utilities?
- What heavy mobile equipment is owned versus leased, and are current values and schedules available?
- Are there any outstanding environmental citations, NOVs, or open reclamation obligations?
