The California Air Resources Board has fined 12 shipping companies a combined $476,750 for failure to switch from high-sulfur diesel “bunker” fuel to cleaner, low-sulfur marine distillate fuel upon entering Regulated California Waters, as required by state law.

ARB said that all companies cited took prompt action after being notified of the violations and, under ARB’s supervision, began complying with state law.
