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 originally established these TMDLs pursuant to a 
consent decree entered in this lawsuit. EPA has modified these TMDLs.

    EPA previously requested the public to provide EPA with any 
significant data or information that might impact the original 30 TMDLs 
in Federal Register Notices: Volume 72, Number 206, pages 60666 and 
60667 (October 25, 2007); Volume 72, Number 209, pages 61355 and 61356 
(October 30, 2007); Volume 73, Number 22, pages 6178 and 6179 (February 
1, 2008).
    EPA now requests that the public provide any water quality related 
data and information that may be relevant to the calculations for these 
30 modified TMDLs. EPA will review all data and information submitted 
during the public comment period and revise the modifications to the 
TMDLs where appropriate. EPA will then forward the modified TMDLs to 
the Louisiana Department of Environmental Quality (LDEQ). The LDEQ will 
incorporate the modified TMDLs into its current water quality 
management plan.

    Dated: August 20, 2008.

P.G., Acting Director, Water Quality Protection Division, Region 6.
