Site Pollution Liability Insurance*

Most businesses have pollution exposures that are often considered incidental to the business's mission. Such environmental liability exposures can arise from materials storage, air emissions from heating or other processes, storm water runoff, spills during natural catastrophes, or even the specter of unknown activities of previous site owners.

Because Commercial General Liability policies, even with a pollution coverage broadening endorsement, may not sufficiently cover pollution risks, many companies purchase Site Pollution Liability insurance to help:

  • Protect assets from unforeseen environmental exposures that could have substantial impact on earnings
  • Protect against natural catastrophes beyond the standard property exposures that typically are already insured
  • Facilitate property transactions and help secure financing
  • Assist in mergers and acquisitions, separating the unknown environmental risk from the business risk
