The Cross-State Air Pollution Rule (CSAPR) is an EPA program that requires member states in the USA to reduce their power plant emissions that contribute to pollution (ozone and/or fine particles) in other US states. CSAPR sets standards for NOx and SO2. CSAPR mandates specific states to lower plant emissions that can lead to soot and smog, and impact air quality and public health not only locally but in regions located hundreds of miles downwind in other states. The EPA describes this rule as “protecting the health of millions of Americans by helping states reduce air pollution and attain clean air standards.”
