Start Preamble

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Notice of availability.

SUMMARY:

This notice announces the availability for comment of the administrative record file for 11 TMDLs and the calculations for these TMDLs prepared by EPA Region 6 for waters listed in the Calcasieu and Ouachita river basins, under section 303(d) of the Clean Water Act (CWA). These TMDLs were completed in response to the lawsuit styled Sierra Club, et al. versus Clifford et al., No. 96-0527, (E.D. La.).

This notice also announces the availability for comment of EPA determinations that TMDLs are not needed for 4 waterbody/pollutant combinations in the Calcasieu and Ouachita river basins because new data show that water quality standards are being met or a TMDL previously has been approved. This proposed action would result in the removal of 4 waterbody/pollutant combinations from the Louisiana 303(d) list.

DATES:

Comments must be submitted in writing to EPA on or before May 22, 2002.

ADDRESSES:

Comments on the 11 TMDLs and the determinations that TMDLs are not needed for 4 waterbody/pollutant combinations should be sent to Ellen Caldwell, Environmental Protection Specialist, Water Quality Protection Division, U.S. Environmental Protection Agency Region 6, 1445 Ross Ave., Dallas, TX 75202-2733. For further information, contact Ellen Caldwell at (214) 665-7513. The administrative record file for these TMDLs and the determinations that TMDLs are not needed are available for public inspection at this address as well. Documents from the administrative record file may be viewed at www.epa.gov/​region6/​water/​tmdl.htm, or obtained by calling or writing Ms. Caldwell at the above address.

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. EPA proposes these TMDLs and determinations that TMDLs are not necessary pursuant to a consent decree entered in this lawsuit.

EPA requests that the public provide any water quality related data and information that may be relevant to the calculations for these 11 TMDLs and any comments relevant to the 4 determinations that TMDLs are not needed. EPA will review all data and information submitted during the public comment period and revise the TMDLs and determinations where appropriate. EPA will then forward the TMDLs to the Louisiana Department of Environmental Quality (LDEQ). LDEQ will incorporate the TMDLs into its current water quality management plan. EPA also will revise the Louisiana 303(d) list as appropriate.
