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.
