State of Texas v. Environmental Protection Agency, No. 17-60088 (5th Cir. 2024)
Annotate this CaseIn a dispute over the classification of two Texas counties under the National Ambient Air Quality Standards (NAAQS) established by the Environmental Protection Agency (EPA), the United States Court of Appeals for the Fifth Circuit upheld the EPA's decision to designate the counties as "nonattainment" for sulfur dioxide emissions. The dispute arose when the EPA initially designated Rusk and Panola counties as nonattainment based on data submitted by the Sierra Club. The EPA later proposed to change the designation to "unclassifiable" after it found the initial data to be potentially erroneous. However, in June 2021, the EPA withdrew the proposal and upheld the initial nonattainment designation. The State of Texas and Luminant Generation Company, companies adversely affected by the nonattainment designation, petitioned for a review of the EPA's decision. The court held that the EPA's decision was not arbitrary, capricious, or unlawful, but rather a valid exercise of the agency's discretion based on its technical expertise and review of complex scientific data. The court also found that the EPA did not misconceive its legal authority or fail to treat like cases alike in its decision-making process.
