In July 2011, the US Environmental Protection Agency (EPA) finalized a rule that affects electric generation plants’ emissions. The Cross-State Air Pollution Rule (CSAPR), requires states to significantly reduce power plant emissions that contribute to ozone and/or fine particle pollution in other states.
Separately, in December, the EPA finalized a supplemental rule that requires five states - Iowa, Michigan, Missouri, Oklahoma, and Wisconsin - to make summertime NOx reductions under the CSAPR ozone season control program.
CSAPR now requires a total of 28 states to reduce annual SO2 emissions, annual NOX emissions and/or ozone season NOX emissions to the 1997 ozone and fine particle and 2006 fine particle National Ambient Air Quality Standards. On February 7, 2012, the EPA issued two sets of minor adjustments to CSAPR.
CSAPR will replace the EPA's 2005 Clean Air Interstate Rule (CAIR).
Breen provides solutions to help meet CSAPR requirements including demonstrations of dry sorbent injection, Fuel Lean Gas Reburn systems and by installing advanced process controls.
