Methods Update Rule for Federal Clean Water Act Analyses

TCEQ's stakeholder meetings and request for stakeholder input on implementing the 2017 Methods Update Rule (MUR) in the Water Quality Division’s permitting programs.

The Environmental Protection Agency has promulgated specific changes to test methods that industries and municipalities use to analyze the chemical, physical, and biological components of wastewater and other environmental samples required by the Clean Water Act (August 28, 2017). The MUR resulted in changes in the approved analytical methods and minimum levels included in Title 40 Code of Federal Regulations (CFR) Part 136.

TCEQ is in the process of implementing this rule in the water quality permit applications and permits and is seeking input from stakeholders. We have updated Appendix E of the Procedures to Implement the Texas Surface Water Quality Standards (IPs) to be compliant with the current approved analytical methods and their corresponding minimum levels.

On July 16, 2020, TCEQ sent stakeholders the most recent revisions to the draft Appendix E of the IPsAdobe Acrobat PDF Document and the response to stakeholder commentsAdobe Acrobat PDF Document. If you have comments on the draft Appendix E please submit them to WQ-MUR@tceq.texas.gov no later than August 17, 2020.
