Various environmental organizations filed petitions for review with the EPA’s Environmental Appeals Board of the agency's approval of an air permit for a proposed California power plant. Avenal Power Center LLC's permit exempts the plant from complying with permitting requirements for greenhouse gas emissions and air quality standards for nitrogen dioxide and sulfur dioxide. The EPA will not require Avenal to comply with the new requirements because EPA received Avenal’s application for a prevention of significant deterioration permit under the Clean Air Act before the standards were proposed. Avenal applied for its permit in 2008. EPA approved Avenal’s application the day after a Federal Judge ordered the agency to approve or deny the application within 90 days. EPA's decision is subject to review by the Environmental Appeals Board with a final decision required by August 27.
