The Ayres Law Group


Ayres Law Group LLP represents clients in highly consequential environmental matters in federal and state courts, with an emphasis on appellate advocacy. In our more than four decades of environmental law practice, our attorneys have handled dozens of federal trial and appellate court cases involving the interpretation and enforcement of the Clean Air Act, National Environmental Policy Act, Atomic Energy Act, Administrative Procedure Act, and other federal environmental and administrative laws.

The firm focuses on environmental litigation related to air pollutionclimate change and energy. We regularly represent clients at all levels of the federal courts, including in the United States Supreme Court, and before various federal agencies. We presently represent a major electric utility and renewable energy company and a national trade association of solar energy companies in litigation regarding EPA regulations issued under sections 111(b) and (d) of the Clean Air Act limiting greenhouse gas emissions from power plants. In recent years we have successfully overturned and defended EPA regulations before the federal courts of appeal and the Nuclear Regulatory Commission on behalf of corporate clients. Other representative work includes authoring briefs in both of the U.S. Supreme Court decisions handed down in 2007, representing the State of North Carolina in a precedent-setting common law nuisance action in federal district court and the U.S. Court of Appeals for the Fourth Circuit, and winning precedential litigation in 2013 before the NRC expanding the jurisdiction of Atomic Safety and Licensing Boards over modifications of nuclear power plants.
