Texas Surface Water Quality Standards as Rule
On April 30, 1997, the three-member commission of TNRCC (now TCEQ) adopted proposed amendments to the 1995 Texas Surface Water Quality Standards (TSWQS), as codified by rule in the Texas Administrative Code (TAC), Title 30, Chapter 307. The 1997 TSWQS became effective as a state rule on April 30, 1997.
TCEQ continues to use the 1997 TSWQS for the maximum temperature criterion found in Appendix A for Segment 1811 (Comal River). This temperature criterion and subsequent revisions of the TSWQS are used in administering its federal permitting programs, depending on which provisions from each revision year EPA has approved. A webpage for each TSWQS revision year describes what actions EPA has taken for that revision and what items are still pending. If EPA either disapproves or is still reviewing a portion of the TSWQS, the language of the prior revision year remains in effect for TCEQ permitting programs created and authorized under the federal Clean Water Act.
Back to topStatus: EPA Approval of the 1997 TSWQS
EPA completed its final action on all revisions to the 1997 TSWQS in March 1998. For information on more recent revisions to the TSWQS (those currently being used in federal permitting such as the TPDES program) see the main Water Quality Standards webpage and select the page for the most recent version. The most current revision of the TSWQS adopted by the commissioners is always in effect for all non-federal programs.
