Clean Air Coalition

Learn about the Central Texas Clean Air Coalition, including its purpose, membership, initiatives and upcoming meetings.


> Attend the next meeting

The Central Texas Clean Air Coalition, or the Clean Air Coalition, is a voluntary, unincorporated association that became affiliated with CAPCOG by a resolution adopted on Nov. 13, 2002. Its purpose:

  • Facilitate the development, adoption, and implementation of clean air plans to maintain compliance with the federal eight-hour ozone standard for the Bastrop, Caldwell, Hays, Travis, and Williamson counties.
  • Establish and monitor a regional effort toward the improvement of air quality.
  • Develop policies and strategies that will provide guidance for each of its independent governing bodies about actions that will achieve clean air in Central Texas. 
  • Work cooperatively to achieve clean air standards that will protect public health and yet allow local governments the flexibility to select measures best suited to each community's needs and resources.
  • Provide CAPCOG Executive Committee with recommendations for administering funding provided by local sources for the purpose of supporting the regional air quality plan or program implementation, assessment , and improvement activities in Central Texas.

CAC membership comprises elected officials from the five-county Austin-Round Rock metropolitan statistical area who represent governmental parties to the Central Texas 8-hour Ozone Flex Plan, an ongoing regional initiative to reduce ozone pollution. Also known as "8-O3 Flex," the plan builds on previous initiatives such as the 1-hour O3 Flex Program and the Early Action Compact and eventually will transition to the Ozone Advance plan. All local governments that signed on to the 8-O3 Flex are members of the CAC:

  • Bastrop County (Commissioner William Pina, First Vice Chair)
  • Caldwell County (Judge Tom Bonn)
  • Hays County (Commissioner Ray Whisenant)
  • Travis County (Judge Samuel Biscoe, Chair)
  • Williamson County (Commissioner Ron Morrison, Second Vice Chair)
  • City of Austin (Council Member Chris Riley)

  • City of Elgin (Council Member Chris Cannon)
  • City of Lockhart (Mayor Lew White)
  • City of Luling (Mayor Mike Hendricks)
  • City of Round Rock (Mayor Alan McGraw)

Since the 8-O3 Flex Plan's adoption, four additional jurisdictions have joined the CAC:

  • City of Georgetown (Council Member Rachael Jonrowe)
  • City of Cedar Park (Council Member Stephen Thomas)
  • City of Sunset Valley (no representative)
  • City of Taylor (no representative)
