TITLE: Control of Emissions from New Marine Compression-Ignition Engines at or Above 30 Liters
per Cylinder
AGENCY: Environmental Protection Agency (EPA)
ACTION: Proposed Rule
SUMMARY: EPA is proposing emission standards for new marine diesel engines with per cylinder
displacement at or above 30 litres (called Category 3 marine diesel engines) installed on U.S. vessels,
under section 213 of the Clean Air Act (CAA. The proposed engine standards are equivalent to the
nitrogen oxides (NOX) limits recently adopted in the amendments to Annex VI to the International
Convention for the Prevention of Pollution from Ships (MARPOL Annex VI) and are based on the
position advanced by the United States Government as part of those international negotiations. The
near-term standards for newly-built engines would apply beginning in 2011. Long-term standards
would begin in 2016 and are based on the application of high-efficiency after-treatment technology.
We are also proposing a change to our diesel fuel program that would forbid the production and sale
of marine fuel oil above 1,000 ppm sulphur for use in the waters within the proposed U.S. ECA and
internal U.S. waters and allow for the production and sale of 1,000 ppm sulphur fuel for use in
Category 3 marine vessels.
This proposal is part of a coordinated strategy to ensure that all ships that affect U.S. air quality meet
stringent NOX and fuel sulphur requirements. In addition, on 27 March 2009, the U.S. Government
forwarded a proposal to the International Maritime Organization (IMO) to amend MARPOL Annex
VI to designate an Emission Control Area (ECA) off U.S. coasts. If this proposed amendment is not
timely adopted by IMO, we intend to take supplemental action to control emissions from vessels
affecting U.S. air quality.
We project that in 2030 this coordinated strategy would reduce annual emissions of NOX and
particulate matter (PM) from ocean-going vessels by 1.2 million and 143,000 tons, respectively.
These reductions are estimated to annually prevent between 13,000 and 32,000 PM-related premature
deaths, between 220 and 980 ozone-related premature deaths, 1,500,000 work days lost, and
10,000,000 minor restricted-activity days. The estimated annual monetized health benefits of this
coordinated strategy in 2030 would be between $110 and $280 billion, assuming a 3 percent discount
rate (or between $100 and $260 billion assuming a 7 percent discount rate. The annual costs would be

significantly less, at approximately $3.1 billion. The proposed regulations also include technical
amendments to our motor vehicle and non-road engine regulations. Many of these changes involve
minor adjustments or corrections to our recently finalized rule for new non-road spark-ignition
engines, or adjustment to other regulatory provisions to align with this recent final rule.
