EPA Goal 1: Climate Change and Improving Air Quality
Toxic air pollutants-also known as Hazardous Air Pollutants or HAPs-are those that are known to cause or suspected of causing cancer or other serious health ailments. The Clean Air Act Amendments of 1990 listed 188 HAPs and addressed the need to control toxic emissions from transportation. In 2001, EPA issued its first Mobile Source Air Toxics Rule, which identified 21 mobile source air toxic (MSAT) compounds as being hazardous air pollutants that required regulation. A subset of six of these MSAT compounds were identified as having the greatest influence on health and included benzene, 1,3-butadiene, formaldehyde, acrolein, acetaldehyde, and diesel particulate matter (DPM). More recently, EPA issued a second MSAT Rule in February 2007, which generally supported the findings in the first rule and provided additional recommendations of compounds having the greatest impact on health. The rule also identified several engine emission certification standards that must be implemented. Unlike the criteria pollutants, toxics do not have National Ambient Air Quality Standards (NAAQS) making evaluation of their impacts more subjective.
To address stakeholders concerns and requests for MSAT analysis during project development and alternative analysis, FHWA developed the Interim Guidance on Air Toxic Analysis in NEPA Documents.

Research: Air, Climate and Energy:
The Air, Climate and Energy (ACE) Research Program promotes innovative, sustainable, and integrated solutions to air pollution and climate change. For example, the ACE Program provides research to EPA’s programs to improve public health and the environment, increase life expectancy, and protect the most susceptible populations. ACE provides models and tools necessary for policy makers at all levels of community and government to make the best decisions.
ACE’s integrated research supports the Agency’s implementation of the Clean Air Act (CAA), especially the National Ambient Air Quality Standards (NAAQS), which set limits on how much tropospheric ozone, particulate matter, carbon monoxide, sulfur dioxide, nitrogen oxides, and lead are allowed in the atmosphere. The program also evaluates the risks associated with hazardous air pollutants, also known as air toxics. ACE is an active participant in the U.S. Global Change Research Program (USGCRP), the interagency Federal effort to improve scientific understanding of climate change and global change.
Beginning in FY2012, the following Research Programs will be integrated into the Air, Climate and Energy Research Program:
• Clean Air Research
• Global Change Research
• Biofuels Research (within the Sustainability Program)
• Mercury Research (within the Human Health and Ecosystems Program)
• Clinger Cohen Act,
• Economy Act
