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.
