Regional Planning Organizations

Because the pollutants that lead to regional haze can originate from sources located across broad geographic areas, EPA has encouraged the States and Tribes across the U.S. to address visibility impairment from a regional perspective. Today, EPA provides funding to five regional planning organizations to address regional haze and related issues. These organizations will first evaluate technical information to better understand how their States and Tribes impact national park and wilderness areas (Class I areas) across the country, and they will then pursue the development of regional strategies to reduce emissions of particulate matter and other pollutants leading to regional haze.

EPA annually sponsors meetings of the Regional Planning Organizations' (RPOs') national work groups. Participants are members of work groups within each RPO.

Map of Regional Planning Organizations

The five regional planning organizations are:
Western Regional Air Partnership (WRAP).Exit EPA disclaimer The WRAP is the successor organization to the Grand Canyon Visibility Transport Commission, which was formed in 1991 and issued recommendations to EPA in 1996 for improving the air quality in the 16 Class I areas on the Colorado Plateau. The Western States Air Resources Council (WESTAR) is working in cooperation with the WRAP. Nine WRAP states (Arizona, California, Colorado, Idaho, Nevada, New Mexico, Oregon, Utah, Wyoming) now have the option of implementing many of the Commission's recommendations within the framework of the national regional haze rule.
