National Compliance Initiative: Cutting Hazardous Air Pollutants
Leaks, flares, and excess emissions from some industries emit hazardous air pollutants (HAPs), or air toxics, that are known or suspected to cause cancer, birth defects, and serious environmental impacts. Recent monitoring shows that facilities typically emit more HAPs than they report. Leaking equipment and improperly operated industrial flares are some of the largest sources of HAP emissions. Improper operation of an industrial flare can result in hundreds of tons of excess HAP emissions.
For FY2017–2019, this initiative was expanded to include addressing air emissions from large product storage tanks. In doing so, EPA focused on identifying and addressing violations of leak detection and repair requirements for product storage tanks.
EPA will identify and address illegal and excess emissions of toxic air pollutants from leaks, tanks, and flares at facilities that have a significant impact on air quality and health in communities.
The following maps and charts show EPA’s actions in targeting and reducing illegal emissions of toxic air pollutants.
