Shore Power for Ocean-going Vessels

This page reviewed January 17, 2014

Overview

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 refered 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 technique(s) that achieve equivalent emission reductions.

What's New

CARB releases Notification and Reporting forms for the Regulator Advisory

As specified in the December 2013 Regulatory Advisory, fleets need submit documentation to ARB to qualify for temporary relief. These forms are available in the "Forms and Tools" section of this website. We are also hosting an informational webinar on March 6, 2014 to discuss the forms.


CARB issues Regulatory Advisory for the At-Berth Regulation

This regulatory advisory describes steps ARB is taking to assist vessel fleets with the transition to the 2014 compliance requirements under At-Berth Regulation. Californiaís ports, terminals, and most of the vessel fleets have made substantial investments in new equipment and practices to transform their operations and meet the requirements of the At-Berth Regulation. These vessel fleets need some flexibility during the transition period from January 1 June 30, 2014, to implement the new practices. The overall goal of this action is to recognize good faith compliance efforts while ensuring that emissions reductions required by the At-Berth Regulation are achieved in a timely manner to provide critical public health benefits for communities near ports.
