Cross-State Air Pollution Rule

The Cross-State Air Pollution Rule (CSAPR) is a rule by the United States Environmental Protection Agency (EPA) that requires member states of the United States to reduce power plant emissions that contribute to ozone and/or fine particle pollution in other states.[1][2] The EPA describes this rule as one that "protects the health of millions of Americans by helping states reduce air pollution and attain clean air standards."[1]

Details

The CSAPR requires 23 United States states to reduce their annual emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) to help downwind states attain the 24-hour National Ambient Air Quality Standards, and 25 states to reduce ozone season nitrogen oxide emissions to help downwind states attain the 8-hour NAAQS.[2]

The states that are required to reduce sulfur dioxide emissions are divided into two groups, both of which must reduce their emissions in 2012. Group 1 is required to make additional emissions reductions by 2014.[2]

History

Date Event
July 6, 2011 The EPA finalized the rule, replacing the EPA's earlier Clean Air Interstate Rule (CAIR) from 2005.[1]
December 15, 2011 The EPA finalized a supplemental rulemaking to require five states - Iowa, Michigan, Missouri, Oklahoma, and Wisconsin - to make summertime NOx reductions under the CSAPR ozone season control program.[1]
February 7, 2012 The EPA issued a minor adjustment to the rule.[1]
June 5, 2012 The EPA issued another minor adjustment to the rule.[1]
August 21, 2012 A D.C. Circuit Court of Appeals overturned the CSAPR.[3][4][5]
