Clean Air Rules of 2004
The actions described here are part of the suite of inter-related
rules collectively known as the
Clean Air Rules of 2004. These rules address ozone and fine particle
pollution, nonroad diesel emissions, and power plant emissions of sulfur dioxide,
nitrogen oxides and mercury.

In the January 30, 2004 Federal
Register, EPA proposed new air rules for reducing emissions
of sulfur dioxide (SO2), nitrogen oxides (NOx), and mercury. EPA
proposed the Interstate Air Quality Rule which focuses on states
whose SO2 and NOx emissions are significantly contributing to fine
particle and ozone pollution problems in other downwind states.
The proposed Interstate Air Quality Rule would cover 29 states in
the Eastern United States and the District of Columbia. In a separate
but closely related action, EPA proposed the Utility
Mercury Reductions Rule for controlling mercury emissions from
power plants. Together, the Interstate Air Quality Rule proposal
and mercury proposal create a multi-pollutant strategy to improve
air quality throughout the U.S.
