CARB Marine Notice 2009-3

Compliance with Phase 1 of the regulations governing Fuel Sulfur and Other Operational Requirements for Ocean-Going Vessels Within California Waters and 24 Nautical Miles of the California Baseline has been required since 1 July 2009 for the main engines, auxiliary engines, diesel electric engines and auxiliary boilers.

In June the California Air Resources Board (CARB) issued Marine Notice 2009-3 advising of the commencement of enforcement of the regulations and reminding owners or operators of ocean-going vessels visiting California ports where they can access further information about the regulations.

In July 2009 the MEPC of  IMO approved the proposal to designate specific portions of the coastal waters of the United States and Canada as an Emission Control Area (ECA). The ECA would be for the control of emissions of nitrogen oxides (NOx), sulphur oxides (SOx), and particulate matter, under the revised MARPOL Annex VI Prevention of Air Pollution from Ships, which was adopted in October 2008 and is expected to come into force on 1 July 2010. It is hoped that once in the ECA is in effect the CARB regulations will be phased out in favour of a U.S. wide emmission control regime. For further information about this ECA see: Further Reduction in SOx Emission Requirements and US/Canadian ECA Proposal.
