Regulatory ChallengeU.S. EPA Tier 4
Figures Source: ”Marine and Locomotive Repowers EPA Presentation from EPA.gov”, EPA, 2011.
Regulation impacts virtually all U.S. flagged vessels
• All marine diesels on U.S. flagged vessels– High and medium speed diesel engines
• > 800 hp (600 kW)
• < 30 liters per cylinder
• New and remanufactured engines
• Emergency standby and national
security exemptions
• Effective date:– 2014 for > 2000 kW
– 2016 for > 1400 kW
– 2017 for > 600 kW
• 40 CFR 1042
