What Is Contractor Pollution Liability?


Contractors pollution liability helps protect companies from the liability and financial loss caused by conditions resulting from pollution due to the performance of their work. Chemicals and toxic gases from broken pipelines, contaminated soil disposal or accidental release of fuel oil are some of the risks the contractor is exposed during a construction project. Pollution incidents can result in a serious harm not only to your operations, but to public health and safety as well as to the environment. Even common substances as salt and fuel oil can harm drinking water sources.


A few examples of types of projects covered by contractor pollution liability includes environmental remediation projects, site restoration and cleanup projects as well as abatement projects and abandoned industrial site projects.


In the last decade, Canada environmental legislation has moved from a more indulgent approach to one of absolute persecution to polluters. Before, pollution accidents were covered under a commercial general liability policy, but now contractor pollution liability coverage is a stand-alone policy, and is excluded from CGL.
