Notice of availability.

SUMMARY:

This notice announces final agency action on 27 TMDLs prepared by EPA Region 6 for waters listed in Louisiana's Mermentau and Vermilion/Teche river basins, under section 303(d) of the Clean Water Act (CWA). This notice also announces final agency action removing 6 waterbody/pollutant combinations from the Louisiana 303(d) list because TMDLs are not needed.

SUPPLEMENTARY INFORMATION:

In 1996, two Louisiana environmental groups, the Sierra Club and Louisiana Environmental Action Network (plaintiffs), filed a lawsuit in Federal Court against the United States Environmental Protection Agency (EPA), styled Sierra Club, et al. v. Clifford et al., No. 96-0527, (E.D. La.). Among other claims, plaintiffs alleged that EPA failed to establish Louisiana TMDLs in a timely manner.
