Contractors pollution liability (CPL) is a contractor-based policy, offered on a claims-made or occurrence basis, that provides third-party coverage for bodily injury, property damage, defense, cleanup, and related defense costs as a result of pollution conditions (sudden/accidental or gradual) arising from contracting operations performed by or on behalf of the contractor. Policies can be offered on a project or blanket program basis. Project policies provide coverage for all operations performed by the insured during the construction period and can include “tail” coverage (extended reporting period (ERP) for claims made policies and completed operations for occurrence policies) to address the statutes of repose in many states or other contractual requirements. Usually, a maximum term of 12–13 years is offered. Additionally, wrap-up programs can be implemented to afford coverage for all contractors regardless of activity undertaken (environmental or nonenvironmental) on a specific project. A blanket program provides coverage on an annual basis for all defined covered operations taking place during the policy term.
