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, as codified by rule in the Texas Administrative Code (TAC), Title 30, Chapter 307. Since then, the three-member commission adopted revisions to the Standards on July 26, 2000 and June 30, 2010.

Status: EPA Approval of the 1997 Standards

EPA must approve the Standards for them to be used for federal permitting programs and other Clean Water Act purposes. EPA completed its final action on all revisions to the 1997 Standards in March 1998. For more information on more recent revisions to the Standards that are currently being used in federal permitting such as the TPDES program, see the main Water Quality Standards webpage.  For non-federal programs, the most current adopted revision of the Standards is in effect.
