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, plaintiffs alleged that EPA failed to establish Louisiana 
TMDLs in a timely manner. EPA established seven of these TMDLs pursuant 
to a consent decree entered in this lawsuit.
