Amendment of Arizona Mercury Rule (R18-2-701, R18-2-733, R18-2-733.01, R18-2-734)

ADEQ is proposing amendments to the state standards for emissions of mercury by coal-fired electric utility steam generating units (EGUs) in R18-2-733, -733.01 and -734 (the “Arizona Mercury Rule”) that would revise those rules to reflect EPA’s repeal of its cap-and-trade program for mercury emissions and adoption of maximum achievable control technology (MACT) standards. Specifically, the amendments would (i) repeal provisions of the Arizona Mercury Rule (R18-2-733 and -733.01) that incorporate and modify the now defunct cap-and-trade program and (ii) amend the emission limits in R18-2-734 to be consistent with the MACT standards.
