Acid Rain Program Benefits Exceed Expectations A new analysis 1 of the Acid Rain Program, established by Title IV of the Clean Air Act Amendments of 1990, estimates annual benefits of the program in 2010 at $122 billion and costs for that year at $3 billion(2000$)—a 40-to-1 benefit/cost ratio. This new analysis includes: Previously unanticipated mercury reductions are quantified. • Health benefits are based upon reductions of fine particle and ozone pollution, not just sulfates. The list of benefits categories is expanded, reflecting EPA’s latest benefit quantification and valuation methodologies. Benefits are Due to Emissions Reductions These quantified benefits are the result of improved air quality and lower acidic deposi- tion in the U.S. and Canada. The Acid Rain Program not only reduced emissions of sulfur dioxide (SO 2 ) and nitrogen oxides (NO X ) from U.S. power generation sources, as Title IV intended, but reduced mercury emissions, as well. To comply with the Acid Rain Program, power plants switched to low sulfur coals (which also contained less mercury) and installed scrubbers to control SO 2 (which also controlled mercury emissions). Attainment Achievements By reducing SO 2 and NO X over a large geographic region, ambient levels of fine particulate matter (PM) and ozone also decline; thus the Acid Rain Program contrib- utes to the National Ambient Air Quality Standards (NAAQS) attainment. In 2010 air quality improvements due alone to the Acid Rain Program: 92 counties will be in attainment with the fine PM NAAQS, and 110 counties will be in attainment with the 8-hour ozone NAAQS. $122 Billion in Benefits for Human Health, Visibility, and Natural Resources Annual health benefits in 2010 of the Acid Rain Program’s reductions of fine PM and ozone, valued at $119 billion, are detailed in Figure 4, along with the Program’s improve-
