The Environmental Protection Agency issued the Clean Air Interstate Rule to curb power-plant emissions in 28 eastern and midwestern states along with the District of Columbia.

The rule requires power plants to reduce the release of toxic sulfur dioxide and nitrogen oxides over the next decade. The EPA expects sulfur dioxide pollution to drop by 73 percent and nitrogen oxide pollution to drop by 61 percent.

The proposed rule doesn't apply to western states.
