Group of States Sues EPA Over Plant Upgrade Rules

LCG, Oct. 28, 2003--Two lawsuits are being brought by a group of 12 states and environmental groups who assert that changes to emissions regulations sought by the Environmental Protection Agency overturn parts of the Clean Air Act.

The states involved in the suits are in the Northeast, and oppose changes promoting "regulatory certainty" on those pollution control technologies that are needed when repairs or maintenance are undertaken at power plants, manufacturing or other industrial facilities. A series of lawsuits that were brought by the EPA under former President Clinton over changes made to older facilities appear not to be supported under the changes the Bush administration has sought.

Under the modifications to "new source review" rules, which are scheduled to go into effect on Dec. 26, replacement of certain parts of a plant that are judged "functionally equivalent" would not trigger requirements that emission controls be installed. The suits are being filed with the U.S. Court of Appeals for the District of Columbia Circuit.
