The California Air Resources Board said it has collected another $653,250 in fines for violations of state air-quality laws.
ARB fined three international shipping companies a combined $440,250 for failure to switch from "bunker" fuel to cleaner, low-sulfur marine distillate fuel upon entering regulated California waters.
Under California law, oceangoing vessels must switch to cleaner fuel within 24 nautical miles of the shoreline a requirement designed to cut down on diesel exhaust emissions.
The fines were levied on Hoegh Autoliners Shipping AS Co. of Oslo, Norway; N.C.N. Corp. Panama; and Twin Phoenix Shipping S.A. of Singapore.
