Defendants are joined by Intervenor-Defendants in their opposition to an award of attorneys' fees. First, they attempt to distinguish this cause from Metropolitan Washington, alleging that that case is inopposite to the instant litigation because it involved a different statute. This contention is meritless. Metropolitan Washington involved analysis of the citizen's suit provision in the Clean Air Act, 42 U.S.C. 7607(f). That statute provided the model for the virtually identical citizen's suit provisions in the ESA and OCSLA, and the reason for enactment of the citizen's suit provision in all three statutes is identical. The Court of Appeals opinion in Metropolitan Washington controls entitlement to attorneys' fees in the instant case.
