TCEQ Adopted Revisions to Standards

At the February 7, 2018 Commission Agenda meeting, the commissioners adopted revisions to the “Texas Surface Water Quality Standards,” as codified by rule in the Texas Administrative Code (TAC), Title 30, Chapter 307. The 2018 Standards became effective as a state rule on March 1, 2018.

The TCEQ is developing a submittal package for the EPA in support of the 2018 revisions to the Standards. The EPA provides notice to the TCEQ whenever approval or other actions are taken on portions of the revised standards. The EPA must approve the 2018 Standards before TCEQ may use them for federal permitting programs and other Clean Water Act (CWA) purposes.

Standards Acted on or Under Review

Portions of the 2000, 2010, and 2014 Standards have been disapproved or are still under review by the EPA. To see what the EPA has acted on, visit the links to each revision year. For the 2010 Adobe Acrobat PDF Document and 2014 Adobe Acrobat PDF Document revisions, there is a highlighted version of the rule language which shows what the EPA has approved or disapproved and what remains under their review.

If a portion is disapproved or still under review by the EPA, the language in the prior revision year remains in effect for CWA purposes. During the EPA’s review of the 2018 Standards, portions of the 1997, 2000, 2010, and 2014 Standards will continue to be used in federal permitting programs such as the Texas Pollutant Discharge Elimination System (TPDES) program. For non-federal programs, the 2018 Standards are in effect unless specifically disapproved by the EPA.
