The US Environmental Protection Agency, in compliance with settlement agreements, has revised standards to reduce air pollution from stationary engines.
The final amendments to the 2010 National Emission Standards for Hazardous Air Pollutants for Reciprocating Internal Combustion Engines reflect new technical information submitted by stakeholders after the 2010 standards were issued.
EPA said the revised standards will reduce capital costs of the 2010 standards by $287 million and annual costs by $139 million.
Pollution emitted from the engines can cause cancer and other serious health effects, EPA said.
