These TMDLs include 22 waters listed with pesticides as a cause of impairment under section 303(d) of the Clean Water Act (CWA). EPA prepared these TMDLs in response to a Court Order dated October 1, 1999, in the lawsuit Sierra Club, et al. v. Clifford et al., No. 96-0527, (E.D. La.). Under this court order, EPA is required to prepare TMDLs when needed for waters on the Louisiana 1998 section 303(d) list by December 31, 2007.

DATES:

Comments on the TMDLs must be submitted in writing to EPA on or before October 15, 2001.

ADDRESSES:

Comments on the TMDLs 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 is available for public inspection at this address as well. Copies of the TMDLs and their respective calculations may be viewed at www.epa.gov/​region6/​water/​tmdl.htm.

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. Discussion of the court order may be found at 65 FR 54032 (September 6, 2000).

EPA will review all data and information submitted during the public comment period and revise the TMDLs where appropriate. EPA will then forward the TMDLs to the Court and the Louisiana Department of Environmental Quality (LDEQ). LDEQ will incorporate the TMDLs into its current water quality management plan.
