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
