Available Water Quality General Permits

View a list of general permits that authorize the discharge of wastewater and/or stormwater into waters in the state.

The discharge of wastewater and certain types of stormwater into or adjacent to water in the state (HTML) must be authorized by the Texas Commission on Environmental Quality (TCEQ). This authorization may come in the form of an individual discharge permit or a general permit. Seeking authorization under a general permit is generally less time-consuming than authorization under an individual permit and usually requires fewer resources.

The status of general permits that are being renewed or amended will be discussed at quarterly Water Quality Advisory Workgroup meetings, which are open to the public.
