615 F.2d 794 (9th Cir. 1980)
Association of Pacific Fisheries v. EPA is a cornerstone Ninth Circuit decision at the intersection of environmental and administrative law.
1) Must EPA prepare a NEPA environmental impact statement when promulgating nationwide effluent limitation guidelines under the Clean Water Act? 2) Were EPA's seafood-processing effluent limitation guidelines arbitrary, capricious, or otherwise not in accordance with law?
NEPA requires a detailed environmental impact statement for major federal actions significantly affecting the quality of the human environment. However, where Congress has established a comprehensive, environmentally focused decision-making framework with procedures that are the functional equivalent of NEPA's EIS process, EPA need not prepare a separate EIS for rulemakings under that framework. Judicial review of Clean Water Act effluent guidelines is in the court of appeals under 33 U.S.C. § 1369(b)(1) and proceeds on the administrative record under the Administrative Procedure Act's arbitrary-and-capricious standard, affording substantial deference to the agency's technical determinations.
The court held that NEPA does not require EPA to prepare an EIS when issuing effluent limitation guidelines under the Clean Water Act because the Act's procedures and substantive mandates are the functional equivalent of NEPA's. The court further held that, on the administrative record, EPA's seafood-processing effluent guidelines were reasonable and not arbitrary or capricious; the petitions for review were denied.
Association of Pacific Fisheries v. EPA is a leading case on NEPA's nonapplicability to certain EPA rulemakings under the functional equivalence doctrine. It teaches that when Congress embeds rigorous, environmentally focused procedures into an agency's organic statute, courts will not reflexively layer on NEPA's EIS requirement. The case also exemplifies deferential judicial review of complex, data-driven environmental regulations, reinforcing that challengers must engage the administrative record and demonstrate genuine arbitrariness, not mere disagreement with policy or technical judgments. For law students, it is essential for understanding CWA structure, direct court-of-appeals review under § 509(b), the contours of agency deference, and strategic considerations in environmental litigation.
