Pollution Liability vs Environmental Impairment Liability

Pollution from OPERATIONS performed by the contractor. Sudden/accidental + gradual pollution events arising from your work activities at customer or job sites. Includes third-party bodily injury, property damage, and cleanup costs related to the contractor's covered operations.

Pollution from OWNED/OPERATED PREMISES. Gradual pollution + sudden release from sites you own or operate. Includes regulatory cleanup mandate (EPA + state DEP), third-party bodily injury, property damage, business interruption from environmental events, transportation pollution while goods are in your care/custody/control.

Contractors who could cause pollution at CUSTOMER sites: plumbers (sewer/drain backup), landscapers (pesticide/fertilizer overspray), roofers (asbestos/lead during tear-off), HVAC contractors (refrigerant release), painters (lead/VOC exposure), demolition contractors, mold-remediation specialists.

Operations with on-site pollution potential: manufacturing facilities, gas stations, dry cleaners, auto body shops, machine shops, storage yards with chemicals, agricultural operations, waste-management facilities, recyclers. Generally needed if you own/lease premises with chemical storage, fuel storage, or industrial processes.

$500-$1,500/year typical for small contractor add-on (CGL endorsement or standalone). Scales with scope of work + cleanup-cost limit chosen. Plumber-specific CPL often ~$500-$1,000/year (per F2 Plumber cost). Higher-hazard demolition + asbestos abatement can run $3,000-$10,000+/year.

Materially more expensive: $1,500-$10,000+/year for small-mid sites; $25,000+/year for industrial sites with significant pollution exposure. Site-specific underwriting required — Phase 1 + sometimes Phase 2 environmental assessment, on-site inspection, regulatory-history review.

Modern CPL covers BOTH sudden/accidental + gradual pollution releases from operations. Older 'absolute pollution exclusion' GL forms exclude essentially all pollution; CPL fills the gap. Most CPL policies are claims-made — retroactive date matters; tail coverage required when changing carriers.

Covers both sudden/accidental + gradual pollution from owned site. Includes the 'inception-of-pollution' claim — pollution that began before the policy but isn't discovered until policy period. Most EIL is claims-made with extensive disclosure requirements for known pre-existing conditions (often excluded).

Some CPL forms include third-party cleanup cost reimbursement. EPA-mandated cleanup of contractor-caused pollution at customer site typically covered. Cleanup at the CONTRACTOR'S OWN site is NOT covered by CPL — that's EIL territory.

Core coverage: cleanup of pollution at the insured's own site mandated by EPA + state DEP. CERCLA (Superfund) liability potentially covered (large carve-outs apply for known pre-existing conditions). State environmental-cleanup laws (state Superfund equivalents) covered. Underground storage tank releases typically covered.

Plumber: CPL for sewer/drain backup work (per F2 Plumber). Standard GL excludes drain-backflow contamination claims; CPL covers them.
Landscaper: CPL for pesticide overspray hitting neighboring property.
Roofer: CPL for asbestos/lead disturbance during tear-off.

Dry cleaner: EIL for perchloroethylene (PERC) groundwater contamination from operations.
Manufacturer: EIL for chemical-storage spills at the facility.
Gas station: EIL for underground storage tank (UST) releases.
Recycler: EIL for stormwater contamination from yard runoff.

Some operations need BOTH. A demolition contractor who also operates a site for material processing needs CPL (operations at customer sites) AND EIL (pollution events at their own processing yard). Premium for both stacks; total $3,000-$15,000+/year common for demolition + processing operations.

Auto body shop is a common dual-need: CPL for customer-vehicle paint/solvent operations + EIL for paint waste storage + spent-solvent disposal at the shop premises. Most large carriers can write both lines under a Commercial Package Policy at modest discount vs separate quotes.
