TCEQ Adopted 2014 Revisions to the Standards

On February 12, 2014, 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 2014 Standards became effective as a state rule on March 6, 2014.

TCEQ submitted the 2014 Standards revisions and supporting documentation to EPA for review and approval on April 23, 2014. EPA provides notice to TCEQ whenever approval or other actions are taken on portions of the revised standards. EPA must approve the 2014 Standards before they may be used in federal permitting programs and for other Clean Water Act purposes.

TCEQ uses provisions from the 1997 and subsequent revisions of the Standards in administering its federal permitting programs, depending on which provisions from each revision year EPA has approved. A webpage for each Standards revision year describes what actions EPA has taken for that revision and what items are still pending EPA action. If EPA either disapproves or is still reviewing a portion of the Standards, the language of the prior revision year remains in effect for CWA purposes.

EPA Review of the 2014 Water Quality Standards

On April 23, 2014, TCEQ submitted a package in support of the adopted revisions to EPA. EPA completed two action letters dated September 23, 2014 and January 6, 2020. These letters do not address all outstanding portions of the rule requiring EPA review. Major sections still under consideration by the EPA include several revised site-specific criteria in Appendix A and Appendix D, several revised segment boundary descriptions in Appendix C, and several site-specific recreational uses and criteria for unclassified water bodies in Appendix G.

A highlighted version of the 2014 Standards rule language shows on which sections of the standards EPA has acted. A key at the beginning of the document specifies what portions of the 2014 Standards EPA has approved, disapproved, taken no action on, or is still reviewing. This document will be updated as additional EPA action letters are received.
