Shore Power for Ocean-going Vessels
This page reviewed February 15, 2017
In December 2007, the Air Resources Board (ARB) approved the "Airborne Toxic Control Measure for Auxiliary Diesel Engines Operated on Ocean-Going Vessels At-Berth in a California Port" Regulation, commonly referred to as the At-Berth Regulation. The purpose of the At-Berth Regulation is to reduce emissions from diesel auxiliary engines on container ships, passenger ships, and refrigerated-cargo ships while berthing at a California Port. The At-Berth Regulation defines a California Port as the Ports of Los Angeles, Long Beach, Oakland, San Diego, San Francisco, and Hueneme. The At-Berth Regulation provides vessel fleet operators visiting these ports two options to reduce at-berth emissions from auxiliary engines: 1) turn off auxiliary engines and connect the vessel to some other source of power, most likely grid-based shore power; or 2) use alternative control technology that achieve equivalent emission reductions.
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.
Vessel Fleet and Terminal Plans due December 1, 2016
The At-Berth Regulation requires that affected fleet operators submit a plan to ARB identifying the compliance option they will use to reduce at-berth emissions at a port and outlining how vessels in the fleet will comply with the requirements of the regulation. Operators of terminals are also required to provide updated plans to ARB outlining how the terminal will provide the necessary infrastructure for affected fleets to comply with the regulation. The submittal of the vessel and terminal plans for the upcoming 70 percent reduction requirement is now due to ARB on December 1, 2016.
