2017 Advisory

The 2017 Advisory informs affected vessel fleets and terminal operators as to how Air Resources Board (ARB) will proceed with enforcement of the Airborne Toxic Control Measure for Auxiliary Diesel Engines Operated on Ocean Going Vessels At-Berth in a California Port (At Berth Regulation), beginning January 1, 2017.   As specified in the Advisory, ARB will offer six possible scenarios, which may apply on a case-by-case basis, with the objective of providing flexibility to fleets that have equipped their vessels to use shore power or contracted to use an alternative control technology to comply with the At-Berth Regulation.  Fleets are expected to make every effort to reduce emissions to meet the requirements of the At-Berth Regulation.  The advisory is available in the "Forms and Tools" section of this website, and is also linked below.
