In the past, claims for pollution liability were mostly covered under a company's business insurance policy. This changed in the 1980's after the industry was hit with many expensive asbestos claims and now this coverage must be purchased separately. Springfield specialists warn that many businesses who should have pollution coverage are left exposed to liability. It's a common misnomer that pollution claims are only filed against large manufacturers or offshore oil companies. In fact, some very common businesses have pollution exposure, and yours could easily be one of them.
