Revision Process
The process to revise the Texas Surface Water Quality Standards (Standards) includes the public and usually occurs every three years. Revisions address new information about pollutants, additional data about water quality conditions in specific water bodies, and new state and federal regulatory requirements.
Stakeholders in the review and revision process include TCEQ, EPA, the public, other governmental agencies, industries, municipalities, environmental groups, and others. Much of the coordination is done through the Surface Water Quality Standards Advisory Work Group. TCEQ revised Standards in 1967, 1973, 1981, 1984, 1988, 1995, 1997, 2000, 2010, 2014, 2018, and 2022.

The preliminary comment period closes at 5:00 p.m. on July 23, 2024.
TCEQ published a notice in the June 21, 2024 issue of the Texas Register requesting preliminary written comments on the Texas Surface Water Quality Standards (Title 30, Texas Administrative Code, Chapter 307) (Standards), which were adopted in 2022. This request for written comments was in preparation for review and revision as needed of the Standards and IPs.
The Standards establish instream water quality requirements for Texas streams, rivers, lakes, estuaries, and other water bodies. TCEQ is directed to establish water quality standards in the Texas Water Code, Section 26.023. The federal Clean Water Act, Section 303(c), requires that states publicly review and revise their water quality standards as needed every three years. Revisions are made to: (1) incorporate new information on potential pollutants, (2) include additional data about water quality conditions in specific water bodies, (3) address new state and federal regulatory requirements, and (4) accommodate public concerns and public goals for water quality in the state.
The TCEQ will review and consider preliminary comments during the development of draft proposals for revisions of the Standards. Written responses to these preliminary comments will not be provided. Any proposed revisions, whether resulting from these comments or not, will be subject to a formal public hearing and a public comment period prior to adoption.
Submit written comments on the Standards by 5:00 p.m. on July 23, 2024 to Ms. Debbie Miller, MC-234, Water Quality Planning Division, Texas Commission on Environmental Quality, P.O. Box 13087, Austin, Texas 78711-3087, or fax them to 512-239-4410. You may submit electronic comments via email to standards@tceq.texas.gov. File size restrictions may apply to comments submitted via email. Reference the Texas Surface Water Quality Standards in your comments.
A copy of the 2022 version of the Standards is available on the Office of the State Secretary’s website .
