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 propo sed engine standards are equivalent to the 
nitrogen oxides (NOX) limits recently adopted in th e 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 woul d 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 th e 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 coordinate d 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 Mar itime 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 suppl emental action to contro l emissions from vessels 
affecting U.S. air quality. 
 
We project that in 2030 this coordinated stra tegy would reduce annual emissions of NOX and 
particulate matter (PM) from ocean-going vessel s by 1.2 million and 143,000 tons, respectively. 
These reductions are estimated to annually preven t 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 estim ated annual monetized health benefits of this 
coordinated strategy in 2030 w ould be between $110 and $280 billi on, assuming a 3 percent discount 
rate (or between $100 and $260 billion assuming a 7 pe rcent discount rate. The annual costs would be G/TBT/N/USA/321/Add.1

  significantly less, at approximately $3.1 billion. The proposed regulations also include technical 
amendments to our motor vehicle and non-road e ngine 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 prov isions to align with this recent final rule.
