(Washington, D.C.-June 29, 2006) On June 29, 2006, EPA announced requirements that will limit air emissions from new stationary diesel engines by up to 90 percent. The stationary compression ignition internal combustion engines are used at facilities such as power plants and chemical and manufacturing plants to generate electricity and to power pumps and compressors.

The requirements will take effect in three increasingly stringent stages beginning in 2007. At full implementation in 2015, EPA estimates that 81,500 new stationary diesel engines will be covered by the requirements and will reduce their air pollutant emissions by more than 68,000 tons each year. The standards also limit the amount of sulfur in the diesel fuel used to run these engines.

The New Source Performance Standards will limit emissions of nitrogen oxides, particulate matter, sulfur dioxide, carbon monoxide, and hydrocarbons from new or reconstructed stationary diesel engines to the same stringent levels required by EPA's non-road diesel engine regulations.
