The CAIR vacatur. A Dilemma for States
- National Association of Clean Air Agencies (NACAA) (United States)
The vacatur of the Clean Air Interstate Rule (CAIR) creates a dilemma for the many states that were relying on CAIR for reductions in emissions of nitrogen oxides (NOx) and sulfur dioxide (SO{sub 2}) from power plants. NOx is an ozone (O{sub 3}) precursor, NOx and SO{sub 2} are precursors to fine particulate matter (PM2.5) and PM2.5 impairs visibility, contributing to regional haze. Thus, reductions in these emissions are important to achieving the 8-hr O{sub 3} and PM2.5 National Ambient Air Quality Standards (NAAQS) and for improving visibility. With the vacatur of CAIR, the reductions States counted on in the near-term (2009-2011) are in jeopardy. Ultimately, Congress will hopefully enact stringent multipollutant legislation targeting EGUs. However, in the meantime, to protect public health from deadly air pollution, states will need to step in to fill the gap and act quickly to restrict air pollutant emissions from EGUs. 1 ref.
