U.S. Domestic Rulemaking
• Final Rule signed in December, 2009
• New engine standards– Tier 2 and 3 NOx limits for U.S. vessels harmonized with
MARPOL Annex VI– HC and CO cap standards for U.S. vessels
• New fuel sales standards– 0.1%S fuel limit for use in ECAs; unless equivalent technology
used– Allow for 0.1%S distillate sales, in U.S., for marine use
• Adopts Annex VI implementation regulations for all vessels operating in U.S. waters

New Annex VI Amendments
• October 2008 Annex VI amendments approved• Global NOx Controls
– Tier 2: 20% reduction from new vessels (2011)
– Existing engine standards
• Global PM and SOx controls– 2012: 3.5% fuel sulfur
– 2020: 0.5% fuel sulfur• Could be delayed to 2025; subject to 2018 fuel availability review
• A country (or countries) can propose to designate an Emission Control Area (ECA), where more stringent standards apply
![Page 13: 0 Office of Transportation and Air Quality Update for Air Directors: Transportation and Air Quality Christopher Grundler Deputy Director NACAA Spring Meeting.](https://reader035.fdocuments.in/reader035/viewer/2022062421/56649e585503460f94b51d24/html5/thumbnails/13.jpg)

force on August 1, 2012
• ECA NOx Controls– Tier 3 NOx 80% reduction new vessels (2016)
• ECA PM and SOx Controls– 1.0% Fuel Sulfur (2010-2014)– 0.1% Fuel Sulfur 2015+
• Up to 96% reduction in SOx• ~85% reduction in PM

Benefits and Costs
• In 2030 the estimated benefits are between $110 and $270 billion
• By 2030, the emission reductions associated with the coordinated strategy will annually prevent:– Between 12,000 and 30,000 PM-related premature deaths– Between 210 and 920 ozone-related premature deaths– About 1,400,000 work days lost– About 9,600,000 minor restricted-activity days
• The estimated costs are much smaller: $3.1 billion

Summary: New OGV Requirements
• Ocean-going Vessels– 40% of NOx and 48% of PM emissions in 2030
– In March 2009, the US proposed (to IMO) to designate US coastlines as Emission Control Areas (ECAs)
– In March 2010, the IMO officially adopted the ECA designation– Fuel Quality Standards
– 30% fuel sulfur reduction by 2012– 97% fuel sulfur reduction by 2015
– Existing engines – 15-20% reduction in NOx starting in 2010
– New engines– 20% reduction in NOx beginning in 2011 – 80% NOx reduction beginning in 2016
– EPA finalized regulations in December 2009 to implement these standards on US-flagged vessels
