What is a Regional Planning Organization (RPO)?

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.  EPA initially provided 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 contributing to regional haze.  Some of the work of the RPOs is
being continued with other regional air organizations.
