WASHINGTON - New interactive tracking tools are now available on EPA’s Web site to help the public follow nation-wide changes in sulfur dioxide (SO2) emissions from coal-fired power plants. Using interactive charts and Google Earth satellite maps, the public can now observe recent changes in SO2 emissions and other indicators at individual coal-fired power plants in the Acid Rain Program.

The Acid Rain Program was established under the 1990 Clean Air Act Amendments requiring power plants to reduce emissions of SO
2 and nitrogen oxides (NOx)—the primary causes of acid rain. Since 1995, the program has achieved significant environmental and public health benefits. In 2008, electric generating units subject to the market-based cap and trade SO2 program emitted 7.6 million tons of SO2, well below the current annual emission cap of 9.5 million tons.
