EMISSION STANDARDS SET FOR LARGE BOATS
On Nov. 23, EPA finalized the first emissions standards for reducing nitrogen oxides (NOx) and particulate matter (PM) emissions from marine diesel engines at or over 50 horsepower. The engines are used for propulsion and auxiliary power on commercial fishing boats, tug boats, Great Lakes cargo ships and ocean-going vessels. The standards will be phased in between 2004 and 2007 depending on engine size and will result in a 24 percent reduction in NOx and a 12 percent reduction in PM when fully phased-in. Currently, marine diesel engines account for about 4.5 percent of total mobile source NOx emissions nationwide and about one percent of PM emissions. Because the standards and the design of marine diesel engines are so similar to the already-regulated non-road and locomotive engines, the costs of this rule are not expected to be high. Initial cost-effectiveness values for NOx emission limits will be about $100 per ton. The final rule will be published in the Federal Register soon and will be available at: https://www.epa.gov/OMSWWW/marine.htm.
