Control of Air Pollution From Heavy-Duty Engines

This advance notice of proposed rule (ANPRM) reviews the need and potential for additional reductions in emissions of oxides of nitrogen (NO X), hydrocarbons (HC), and particulate matter (PM) from mobile source heavy-duty engines (HDEs), announces EPA's intent to establish new emission controls for highway heavy-duty engines, and also describes EPA's plans to work cooperatively with engine and equipment manufacturers to consider additional reductions from nonroad (off-highway) heavy-duty engines. Ozone pollution poses a serious threat to the health and well-being of millions of Americans and a large burden to the U.S. economy. Many ozone nonattainment areas face great difficulties in reaching and maintaining attainment of the ozone health-based air quality standards in the years ahead. Recognizing this challenge, states, local governments and others have called on EPA to promulgate additional national measures to reduce NO X and HC in order to protect the public from the serious health effects of ozone pollution. The control of PM emissions from HDEs is also a priority for these stakeholders. In response to the need for national pollution reduction measures, EPA has initiated discu
