Notice of availability.

SUMMARY:

This notice announces final agency action on 11 TMDLs prepared by EPA Region 6 for waters listed in Louisiana's Ouachita river basin, under section 303(d) of the Clean Water Act (CWA). This notice also announces final agency action removing 4 waterbody/pollutant combinations from the Louisiana 303(d) list because TMDLs are not needed.

Documents from the administrative record files for the 4 determinations that TMDLs are not needed and for 11 the TMDLs, including TMDL calculations and responses to comments, may be viewed at www.epa.gov/​region6/​water/​tmdl.htm.

In 1996, two Louisiana environmental groups, the Sierra Club and Louisiana Environmental Action Network (plaintiffs), filed a lawsuit in Federal Court against the EPA, styled Sierra Club, et al. v.
