Federal regulations require that states hold public hearings at least once every three years to review applicable surface water quality standards and, as appropriate, adopt new or modified standards, taking into consideration public concerns, EPA guidance, and new scientific and technical information. This process is called a triennial review. The triennial review also provides an opportunity to discuss the priorities and commitments the agency makes with EPA and others regarding surface water quality standards.
A previous triennial review for the Surface Water Quality Standards of Louisiana began on January 20, 2016 and the results of these triennial review efforts were developed into a rule (WQ097) which updated portions of the water quality standards found in LAC 33:IX.Chapter 11. The final rule for WQ097 was published in the November 2020 edition of the Louisiana Register and approved by EPA on February 1, 2021.
The Environmental Regulatory Code version of LAC 33:IX, Water Quality, Subpart 1. Water Pollution Control, Chapter 11 Surface Water Quality Standards, can be accessed electronically at:
Triennial Cleanup Rule (WQ108)
Four errors were found in the text of the previous triennial review (WQ097): 1) the deletion of the word “use” at LAC 33:IX.1109.C; 2) the extraneous word “are” at LAC 33:IX.1109.C.3.a; & 3) and 4) inaccurate descriptions of Subsegments 031002 and 041901 at LAC 33:IX.1123.Table 3. This cleanup rule (WQ108) will correct these four errors. This rule will appear in the April 2021 edition of the Louisiana Register and will have a public comment period that expires at 4:30 p.m. on June 1, 2021. A public hearing will be held on May 25, 2021 at 1:30 p.m. in the Galvez Building, Oliver Pollack Conference Room.
