2014 Texas Surface Water Quality Standards

Links to information about the 2014 revision of the Texas Surface Water Quality Standards.

At the February 12, 2014 TCEQ Commission Agenda meeting, the Commissioners adopted revisions to the Texas Surface Water Quality Standards (TSWQS). The EPA must approve the 2014 TSWQS in order for them to be used for federal permitting programs and other Clean Water Act purposes. During the EPA’s review of the 2014 TSWQS, both the 1997 and 2010 TSWQS will continue to be used in federal permitting programs such as the TPDES program.

The 1997 TSWQS remain in effect for those portions of the 2000 and 2010 TSWQSnot approved by EPA. For non-federal programs, the 2014 standards are in effect unless specifically disapproved by EPA
