Air Central Texas (ACT) is an initiative to reduce exposure to air pollution in Bastrop, Caldwell, Hays, Travis, and Williamson Counties through voluntary actions to reduce emissions and tools for the public to avoid exposure to high pollution levels when they occur. Participants include local governments, regional and state government agencies, non-profit groups and institutions, and businesses. ACT works to provide the public with information about Central Texas Air Quality, support existing air quality programs, and motivate everyone to make decisions that are Air Aware.
