Data updated July 2003 - Unless otherwise noted, the data presented throughout this website reflect EPAs 2003 modeling and analysis of the Clear Skies Act, introduced in Congress in February 2003. The analysis reflects changes in the legislation and is based on the most up to date modeling of emissions monitoring and air quality data available. |
Clear Skies would set strict, mandatory emissions caps on three of the most harmful air pollutants from power generators -- sulfur dioxide (SO2), nitrogen oxides (NOx), and mercury. President Bush first announced the Clear Skies Act on February 14, 2002. Clear Skies legislation was first introduced in both Houses of Congress in July 2002. The program was reintroduced in the US House of Representatives (HR 999) and the US Senate (S. 485) as the Clear Skies Act of 2003 on February 27, 2003. Clear Skies would modify the emission reductions and timetables announced by the President to cut power plant emissions of these pollutants by 70 percent, eliminating 35 million more tons of these pollutants in the next decade than the current Clean Air Act. Analytical data generated by state-of-the-art EPA computer modeling shows
that nationwide reductions of these three harmful pollutants would have
striking results: Every part of the country where power plants contribute
significantly to air pollution, most notably, the Northeast, Southeast,
and Midwest, would see vast improvements in air quality. Many cities and
towns would meet air quality standards for the first time in years.
