Why is EPA looking at new emission controls for Recreational Marine Diesel Engines?
We already require emission controls for commercial marine diesel engines; the recreational engines are capable of using similar emission control strategies. Our analysis shows that recreational marine diesel engines emit about 25,000 tons of hydrocarbons plus nitrous oxides (HC+NOx) each year across the United States. These emissions help form smog and contain toxic compounds such as benzene, so reducing them would benefit our health and environment. The Clean Air Act requires us to set emission standards that address these problems. These impacts are described in more detail in “FAQ: Environmental Impacts of Recreational Vehicles and Other Nonroad Engines” [EPA420-F-01-030].
