Acid Precipitation Control Act of 1981

[AI summary unavailable — showing source text] Acid Precipitation Control Act of 1981 - Amends title I of the Clean Air Act (Air Pollution Prevention and Control) to establish a new program (Acid Precipitation Control) to: (1) regulate acid precipitation precursor emissions of sulfur dioxide and nitrogen oxide; and (2) reduce the transport of air pollutants across international boundaries. Establishes an "acid precipitation mitigation region" consisting of 31 States (east of or bordering the Mississippi River) and the District of Columbia. Requires States in the region to reduce, prior to December 31, 1991, sulfur dioxide emissions from all major stationary sources by an amount equal to 85 percent of the actual 1980 sulfur dioxide emissions from all major emitting powerplants (fossil-fuel-fired electric powerplants with specified emissions levels) within such States. Disregards, for purposes of determining such reduction, any emissions from a separate generating unit or units of such powerplants that are subject to new source performance standards. Sets forth formulas for determining the maximum required reduction for any State, based on annual Statewide utility sulfur dioxides emissions rates. Directs the Administrator to: (1)…
