Where We Excel


Vinson & Elkins Clean Air Act (CAA) practitioners work closely with all sectors of the energy industry, including electric utilities, pipeline companies, refiners, exploration and production companies, and bulk storage terminal operators, as well as chemical manufacturers, consumer products companies, waste management companies, and similar enterprises in permitting, compliance, and enforcement matters arising under federal and state air quality laws and regulations.

Our representations include the following:

  • Obtaining and renewing permits for construction and operation of air emission sources, including contested-case permitting proceedings
  • Defending challenges to permits
  • Counseling regarding compliance issues arising under rules and permits

Throughout Texas and many other regions of the country, our CAA lawyers have assisted clients with obtaining and defending the issuance of permits for controversial projects, including coal-fired power plants and waste disposal facilities. We have played leading roles in the judicial review of major CAA regulatory initiatives. Our practitioners have defended clients in enforcement cases initiated by the U.S. Environmental Protection Agency (EPA), state and local authorities, and citizen groups.
