Start Preamble

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Notice of availability.

SUMMARY:

This notice announces final agency action on 98 TMDLs prepared by EPA Region 6 for waters listed in Louisiana's Calcasieu and Ouachita river basins, under section 303(d) of the Clean Water Act (CWA). This notice also announces final agency action removing 20 waterbody/pollutant combinations from the Louisiana 303(d) list because TMDLs are not needed. The EPA evaluated these waters and prepared the 98 TMDLs needed in response to a consent decree entered in the lawsuit Sierra Club, et al. v. Clifford et al., No. 96-0527, (E.D. La.). Documents from the administrative record files for the 20 determinations that TMDLs are not needed and for the 98 TMDLs, including TMDL calculations and the responses to comments, may be viewed at www.epa.gov/​region6/​water/​tmdl.htm.

EPA believes that the public notice and comment period provided for these TMDLs was adequate. During the comment period, EPA received over 400 pages of comments from numerous commenters, including the parties requesting more time. EPA believes that it has appropriately responded to the comments received. Furthermore, EPA is establishing these TMDLs pursuant to deadlines established in a consent decree in the case styled Sierra Club, et al. v. Clifford et al., No. 96-0527, (E.D. La.) which does not at this late date permit EPA to grant additional time for public comment, absent relief from the court, which the Agency does not believe is necessary to seek here. However, EPA will continue to accept information submitted regarding potential errors in the TMDL, and/or to meet with parties to discuss potential errors. If the Agency determines that errors were made, it will issue a correction notice or revise the TMDL, as appropriate.

The administrative record files may be obtained by calling or writing Ms. Caldwell at the above address. Please contact Ms. Caldwell to schedule an inspection.

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 EPA, styled Sierra Club, et al. v. Clifford et al., No. 96-0527, (E.D. La.). Among other claims, the plaintiffs alleged that the EPA failed to establish Louisiana TMDLs in a timely manner.
