Allowable Emissions and Unallowable Discretion: EPA Acid Rain Regulations Violate Congressional Intent of the 1990 Clean Air Act Amendments
Editors' Summary: In 1993, EPA issued its final rules for sulfur dioxide allowance allocations under the acid rain provisions added to the Clean Air Act by the Clean Air Act Amendments of 1990 (1990 Amendments). As part of these rules, EPA interpreted the term "allowable 1985 emissions rate" in CAA § 402(18) to mean that all sulfur dioxide emissions from utility plants must be expressed on an annualized basis. EPA incorporated this interpretation into a regulation known as the "emissions limitation annualization factor."
