TCEQ Adopted Revisions to Standards
On September 7, 2022, the commissioners adopted revisions to the Texas Surface Water Quality Standards, as codified by rule in Texas Administrative Code, Title 30, (30 TAC), Chapter 307. The 2022 Standards became effective as a state rule on September 29, 2022.
TCEQ submitted the 2022 Standards revisions and supporting documentation to EPA for review and approval on November 7, 2022. EPA must approve the 2022 Standards before TCEQ may use them for federal permitting programs and other Clean Water Act (CWA) purposes.
Back to topStandards Acted on or Under Review
EPA is still reviewing portions of the 2000, 2010, 2014, 2018, and 2022 Standards. See what EPA has approved, disapproved, or is still reviewing for the three most recent revision cycles in the following documents:
If a portion of the Standards is disapproved or still under review by EPA, the language in the last EPA-approved revision remains in effect for CWA purposes. During EPA’s review of the 2022 Standards, we will use standards established in other years based on the permitting program.
- Federally delegated programs, such as the Texas Pollutant Discharge Elimination System (TPDES) program, will continue to use portions of the 1997, 2000, 2010, 2014, and 2018 Standards.
- Non-federal programs will use the 2022 Standards unless specifically disapproved by the EPA.
