Sand & Gravel Insurance Cost: Ranges + Calculator
A sand & gravel operation's signature exposures — fugitive dust, silt and sediment runoff into a stream, water contamination — are exactly what a standard general liability policy's pollution exclusion carves out. That is why a dedicated pollution / environmental policy is the coverage that separates a real aggregate program from a generic contractor policy. These are also MSHA-regulated worksites (the Federal Mine Safety and Health Act), which shapes the safety and workers'-comp picture. Our own quote data shows these operators request general liability first — the page's job is to add pollution and the heavy-equipment lines.
As an industry-typical estimate, an aggregate operation runs well into five figures annually — roughly $15,000–$60,000+/year across general liability, pollution/environmental, contractors' heavy equipment (inland marine), commercial auto on the haul trucks, and payroll-rated workers' compensation — driven mostly by fleet size and limits. No insurance bureau publishes aggregate-mining premiums and no reliable public benchmark exists, so every dollar here is a broad estimate; each coverage fact is sourced to a named authority (IRMI, MSHA, III).

Coverage lines a sand & gravel operation typically carries (industry-typical estimates):
- Pollution / environmental liability: the trade-defining line — dust, silt runoff, and water contamination are removed by the standard CGL pollution exclusion, so a dedicated policy is required. IRMI pollution exclusion.
- Heavy equipment (inland marine): excavators, loaders, crushers, and conveyors on-site and in transit. III inland marine.
- Commercial auto: haul and dump trucks — typically the largest single line. III commercial auto.
- Workers' compensation: mining is a high-hazard, federally MSHA-regulated occupation. MSHA mission.
Fleet size, haul radius, proximity to water, and required limits are primary rating factors.
