On September 16th the State of Texas filed four motions to prevent the Environmental Protection Agency (EPA) from implementing new federal regulations. Specifically, Texas petitioned the U.S. Court of Appeals for the D.C. Circuit to stay the EPA’s greenhouse gas Endangerment Finding, the Light-Duty Vehicle Rule, the Prevention of Significant Deterioration (PSD) Interpretive Rule, and the Tailoring Rule.


Court documents filed by the State explain that the EPA’s Endangerment Finding is legally unsupported because the agency outsourced its legally mandated “scientific assessment” to the Intergovernmental Panel on Climate Change (IPCC), which had the objectivity, reliability and propriety of its scientific assessments called into question after a scandal erupted late last year.
