The Acid Rain Program requires major emission reductions of SO2 and NOx from the power sector. Since the program began in 1995, the Acid Rain Program has achieved significant emission reductions.
The earlier reports highlight the results of the Acid Rain Program. In 2010, EPA began producing reports that combined the results of the ARP, the Clean Air Interstate Rule, and the former NOx Budget Trading Program into a single yearly report.
