Revising the Texas Surface Water Quality Standards

Summary of how the standards are revised.

Revision Process

The process to revise the Texas Surface Water Quality Standards (Standards) includes the public and is usually conducted  every three years. Revisions address new information about pollutants, additional data about water quality conditions in specific water bodies, and new state and federal regulatory requirements.

Stakeholders in the review and revision process include the TCEQ, EPA, the general public, other governmental agencies, industries, municipalities, environmental groups, and others. Much of the coordination is done through the Surface Water Quality Standards Advisory Workgroup. There have been revisions to the Standards in 1967, 1973, 1981, 1984, 1988, 1995, 1997, 2000, 2010, 2014, and 2018.

The Procedures to Implement the Texas Surface Water Quality Standards (RG-194) (Implementation Procedures), which explain how the Standards are used in wastewater permitting, are typically reviewed and revised along with the Standards.
