Water Quality Management

Volume 4 updates subject to EPA approval

Volume 4, Appendix A provides a complete listing of all subsegment descriptions by basin.  These subsegment descriptions were previously on public notice in rule WQ097 and WQ106.  Additionally, Subsegments for 031002 and 041901 had inaccurate descriptions in WQ097 and will maintain their original descriptions in Volume 4, Appendix A. The purpose of this revision to Volume 4 and Appendix A is to update the subsegment descriptions to be consistent with LAC 33:IX.Chapter 11. 

The March 2021 edition of the Louisiana Register has a potpourri notice (2103Pot01) for these proposed revisions https://www.doa.la.gov/Pages/osr/reg/regs2021.aspx.  Written comments regarding the proposed revision must be received no later than April 20, 2021, at 4:30 p.m., and should be sent to Jamie Phillippe, Office of the Environmental Assessment, Water Quality Planning and Assessment Division, Box 4314, Baton Rouge, LA 70821-4314 or by e-mail to WQ.Standards@la.gov.
