The Cross-State Air Pollution Rule (CSAPR) a program run by the United States Environmental Protection Agency (EPA) that requires certain states to reduce power plant emissions that contribute to ozone and/or fine particle pollution that cross the borders into other states. The Cross-State Air Pollution Rule (CSAPR) sets new standards for power plants that emit nitrous oxide (NOx) and sulphur dioxide (SO2). CSAPR went into effect in January 1, 2015, after a few years of litigation, for SO2 and NOx pollutants. The EPA views this rule as one that “protects the health of millions of Americans by helping states reduce air pollution and attain clean air standards.” If your company has a facility regulated under CSAPR, Emission Advisors come tailor a specific plan to optimize compliance costs for your firm.
