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's order may be found at 65 FR 54032 (September 6, 2000).
