Air Pollution Permits in Your Neighborhood

This map shows all permit applications in Texas to release harmful pollutants into our air. The map shows both locations of potential new polluting facilities (e.g. a proposed concrete batch plant or chemical processing plant) as well as requests from existing ones to emit even more pollution as well as opportunities to participate in public meetings regarding pending permit applications.

The map is updated on a weekly basis, using publicly available data from the Air Permits Division of the Office of Air at the Texas Commission on Environmental Quality (TCEQ).

Each dot represents an application that can be clicked on for more information, so you can stay up to date on how industrial air pollution may affect air quality in your area.

Every day, the Texas Commission for Environmental Quality (TCEQ) collects and publishes data about air pollution in Houston.

Air Alliance Houston has put together a mapping tool called BREATHE (Bringing Research Education and Advocacy Together for Houston’s Environment) in an effort to make this data more accessible to the public.

This tool enables you to explore information regarding your neighborhood, such as where environmental hazards and public air monitors are located, whether your neighbors have submitted complaints to regulatory agencies, where illegal air pollution releases have occurred, and other information that can help give a better sense of what is going on in your community.
