EPA Standardizes Process to Petition for Objecting to Title V Air Permits

On February 5, the U.S. Environmental Protection Agency (EPA) issued a final rule in the Federal Register to streamline the process to petition the agency to object to state-issued Clean Air Act Title V air permits. The rule changes petition content and format requirements to describe the information a petition needs to include in order for EPA to review a claim of permit or permit process deficiency. With this rule, EPA also requires delegated state permitting authorities to respond in writing to “significant” comments while permitting authorities determine the significance of comments. Pursuant to the revised regulation, state permitting authorities must also submit to EPA a “statement of basis” that describes the legal and factual basis for the permit terms and conditions to be available during the public comment period and the agency’s 45-day review period.

D.C. Circuit Denies Requests to Expedite or Pause Case Over California Waiver to Regulate Vehicle Emissions

In Union of Concerned Scientists v. NHTSA, No. 19-1230, the U.S. Court of Appeals for the District of Columbia Circuit (D.C. Circuit) has denied the motion filed by the National Highway Traffic Safety Administration (NHTSA) and the Environmental Protection Agency (EPA) to expedite petitions for review challenging the agencies’ rule preempting California’s authority to set its own vehicle emissions standards. In the short per curiam order issued on February 4, the D.C. Circuit explained that the agencies have not articulated “strongly compelling” reasons to expedite the litigation. Last December, the agencies asked the D.C. Circuit to hear the case as early as this spring arguing that the standards in question are “immediately impacting” the automotive sector of the U.S. economy. The D.C. Circuit also denied the petitioners’ motion to hold the petition in abeyance pending resolution of a similar case in the U.S. District Court for the District of Columbia, which will decide on proper venue for the litigation.
