View Rule

The Coast Guard is proposing regulations to carry out the provisions of Annex VI of the MARPOL Protocol, which is focused on the prevention of air pollution from ships.  The Act to Prevent Pollution from Ships has already given direct effect to most provisions of Annex VI, and the Coast Guard and the Environmental Protection Agency have carried out some Annex VI provisions through previous rulemakings.  This proposed rule would fill gaps in the existing framework for carrying out the provisions of Annex VI.  Chapter 4 of Annex VI contains shipboard energy efficiency measures that include short-term measures reducing carbon emissions linked to climate change and supports Administration goals outlined in Executive Order 14008 titled Tackling the Climate Crisis at Home and Abroad.  This proposed rule would apply to U.S.-flagged ships.  It would also apply to foreign-flagged ships operating either in U.S. navigable waters or in the U.S. Exclusive Economic Zone. 

Statement of Need:

The Coast Guard is proposing regulations to carry out the provisions of Annex VI of the MARPOL Protocol, which is focused on the prevention of air pollution from ships.  The Act to Prevent Pollution from Ships has already given direct effect to most provisions of Annex VI, and the Coast Guard and the Environmental Protection Agency have carried out some Annex VI provisions through previous rulemakings.  This proposed rule would fill gaps in the existing framework for carrying out the provisions of Annex VI and explain how the United States has chosen to carry out certain discretionary aspects of Annex VI.  This proposed rule would apply to U.S.-flagged ships.  And it would also apply to foreign-flagged ships operating in U.S. navigable waters or in the U.S. Exclusive Economic Zone.

Summary of the Legal Basis:

Section 4 of the Act to Prevent Pollution from Ships (Pub. L. 96-478, Oct. 21, 1980, 94 Stat 2297), as reflected in 33 U.S.C. 1903, directs the Secretary of Homeland Security to prescribe any necessary or desired regulations to carry out the provisions of the MARPOL Protocol.  The "MARPOL Protocol" is defined in 33 U.S.C. 1901 and includes Annex VI of the International Convention for the Prevention of Pollution from Ships, 1973.

Anticipated Costs and Benefits:

USCG anticipates the costs for the proposed rule to come primarily from additional labor for 5 requirements including overseeing surveys; developing and maintaining a fuel-switching procedure; recording various data during each fuel switching; developing and managing a Volatile organic compounds (VOC) management plan; crew member to calculate and report the attained Energy Efficient Design Index (EEDI) of the vessel, and crew member to develop and maintain the Ship Energy Efficiency Management Plan (SEEMP). USCG expects the proposed rule to have unquantified benefits from reduction in fatalities and injuries due to pollutant in engine emissions, and also reduced risk of retaliation due to breaching international agreement.
