Control of Emissions of Air Pollution From New CI Marine Engines at or Above 37 kW

Короткий зміст

In this action, EPA is proposing an emission control program for new compression-ignition marine engines rated at or above 37 kilowatts. The affected engines are used for propulsion and auxiliary purposes in a wide variety of marine applications. The standards proposed for these engines would require substantial reductions in oxides of nitrogen and particulate matter emissions to correspond with the next round of emission standards for comparable land-based engines. The proposed standards are expected to provide a significant reduction in oxides of nitrogen and particulate matter emissions from this source. When combined with other mobile source emission control programs, the program described in this action will help provide long- term improvements in air quality in many port cities and other coastal areas. Overall, the proposed program would provide much-needed assistance to states facing ozone and particulate air quality problems, which can cause a range of adverse health effects for their citizens, especially in terms of respiratory impairment and related illnesses. The persons potentially affected by this action are those who manufacture new compression-ignition marine engines
