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.

Renewal of the Multi-Sector General Permit No. TXR050000

The TCEQ is proposing to renew and amend the Multi-Sector General Permit (MSGP) TXR050000, which authorizes discharges of stormwater from certain industrial activities. The current permit expires on August 14, 2021. The comment period ended on January 15, 2021. The commission is expected to take action on the draft permit on July 14, 2021.

UPDATE  Renewal of the Aquaculture General Permit No. TXG130000

On March 31, 2021, the commission re-issued the Aquaculture General Permit TXG130000, which authorizes the discharge of wastewater from aquaculture facilities and other activities related to aquaculture into or adjacent to water in the state. Facilities that are currently authorized under the general permit are required to submit a Notice of Intent form by July 17, 2021 to continue their authorization. Failure to submit a Notice of Intent form by the deadline will result in the authorization expiring.

UPDATE Renewal of the Concrete Batch General Permit No. TXG110000

TCEQ is proposing to renew and amendment the Concrete Batch General Permit TXG110000 which authorizes discharges of facility wastewater and stormwater associated with industrial activities into or adjacent to water in the state from ready-mixed concrete plants, concrete products plants, and their associated facilities (SIC 3271, 3272, and 3273). The current permit expires on November 7, 2021. The draft permit is currently under development.

UPDATE Renewal of the Pesticide General Permit No. TXG870000

The current permit expires on November 2, 2021. The draft permit is currently under development.

UPDATE Amendment of the Construction General Permit No. TXR150000

The TCEQ is proposing to amend (without renewal) the Construction General Permit (CGP) TXR150000, which authorizes stormwater discharges from construction sites into surface water in the state. The primary purpose of the amendment is to expand the applicability of the general permit to include non-exempt stormwater discharges into surface water in the state from construction activities associated with crude oil and natural gas exploration, development, and production. Facilities that are currently authorized under this general permit will not be affected by this amendment. The draft permit is currently under development.
