Insurance for the oil industry varies by each company’s policy. There are usually limits on pollution, either excluded or limited. This could be one of the greatest possible exposures. Anyone who owns land with wells on it should get a certificate of insurance from the operator and those involved in the operation. Verify that the certificate discloses the pollution exposure and it’s limits.
