The Oil Pollution Act 1990 of the USA requires the operator of a tank vessel or non-tank vessel in US waters to have oil pollution liability insurance up to specified limits of liability, which are periodically revised upwards. A US Coast Guard Certificate of Financial Responsibility (COFR) must be carried by ships of over 300 GT to evidence the insurance cover. Certain US states, e. g. California, have their own oil pollution insurance requirements.
