Particulate Matter (PM) Standards
Announcements
June 14, 2012 - The Environmental Protection Agency is proposing revisions to the National Ambient Air Quality Standards for particulate matter. These revisions would strengthen the annual "primary" fine particle standard to protect public health and would establish a separate "secondary" fine particle standard to protect visibility in urban areas.

The Clean Air Act requires EPA to set national air quality standards for particulate matter and five other pollutants considered harmful to public health and the environment (the other pollutants are ozone, nitrogen oxides, carbon monoxide, sulfur dioxide and lead). The law also requires EPA to periodically review the standards to ensure that they provide adequate health and environmental protection, and to update those standards as necessary.
