The California Air Resources Board has issued a Marine Notice reminding owners and operators that the requirements under the CARB OGV Fuel Regulation remain in effect. The reminder states that regulations such as the existing North American Emission Control Area (ECA) requirements and the International Maritime Organization (IMO) fuel sulphur limit of 0.5% do not change the requirement to use marine distillate grade fuel (marine gas oil or marine diesel oil) with a maximum sulphur level of 0.1% while operating auxiliary diesel and diesel-electric engines, main propulsion diesel engines, and auxiliary boilers on ocean-going vessels within Regulated California Waters (all waters within 24 nautical miles of the California baseline). The regulation does not allow compliance via scrubbers. Only the low sulfur distillate grades of fuel can be used to comply with the CARB OGV Fuel Regulation.
