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.



March 2015 Regulatory Advisory

The March 2015 Regulatory Advisory is inform affected fleets of the proposed schedule for considering amendments to the At-Berth Regulation and to explain administrative changes in implementation during the time needed to develop amendments to the Regulation. As specified in the Advisory, fleets are required to provide the following verification of their use of the advisory through the Quarterly Reporting Form. In addition, Scenario 1 requires immediate notification when a berth is unavailable. ARB staff may ask fleets to provide additional information to support their good faith effort claims.

Fleet Emission Credit Forms:

Fleet emission credits are at-berth NOx and PM emission reductions achieved by a fleet at a particular port prior to 2010 or in excess of the 2010 and 2012 emission reduction requirements. Only fleet operators choosing the equivalent emissions reduction option can accrue and use fleet emission credits. Credits are calculated on a case by case basis. Contact ARB through for assistance with fleet emission credits.
