On May 30, a panel of the U.S. Court of Appeals for the DC Circuit decided the case of Environmental Integrity Project, et al. v. EPA. Affirming the District Court, the Court of Appeals held that Exemption 4 of the Freedom of Information Act (FOIA) trumps Clean Water Act Section 308’s authorization to the Environmental Protection Agency (EPA) to disclose to the public certain commercial and financial information EPA had obtained from power plant operators.
Reviewing the text of both FOIA and the CWA, the Court of Appeals notes that Exemption 4 was enacted in 1967, or a few years before the CWA was enacted and concludes that FOIA’s exemptions, being part of the Administrative Procedure Act, cannot be supplanted by later-enacted legislation that does not expressly revoke that exemption.
