Water Quality Management

Water Quality Management Plan (WQMP) 

Volume 4, Appendix A of the Water Quality Management Plan is being revised to reflect changes described in rule WQ111. The June 2023 edition of the Louisiana Register has a potpourri notice (2306Pot02) for these proposed revisions at (https://www.doa.la.gov/media/hjsjxxbz/2306.pdf). The only change being made to the body of Volume 4 is the document’s date (https://edms.deq.louisiana.gov/app/doc/view?doc=13858221&key=bc5ca5f0-f937-41af-b29e-45737b7b4d3c).  Wetland assimilation subsegments will be assumed back into their parent subsegments, making the need to remove their subsegment descriptions from Appendix A (https://edms.deq.louisiana.gov/app/doc/view?doc=13858222&ob=yes&child=yes). After approval from EPA, all mapping databases (e.g., Make-A-Map) will be updated to reflect these changes.

Written comments regarding the proposed revision must be received no later than July 20, 2023, 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.
