Utility Water Act Group v. Riverkeeper, Inc., et al.

Questions presented

SCOTUS records, cert granted 14 Apr 2008

1. Whether § 316(b) of the Clean Water Act, 33 U.S.C. § 1326(b), which specifies that standards set under §§ 301 or 306 of the statute shall require that cooling water intake structures reflect the “best technology available for minimizing adverse environmental impact,” prohibits the United States Environmental Protection Agency (“EPA”) from considering the cost of a technology in comparison to the level of control it achieves and to the environmental “benefit” of that level of control?
2. Whether § 316(b) prohibits EPA from authorizing existing facilities to use restoration measures (for example, fish stocking or habitat restoration) that, taken collectively with the existing characteristics of the cooling water intake structure, ensure that the intake structure minimizes “adverse environmental impact”?

Opinion summary

Etalia.ai summary of the majority opinion

The case addressed whether the Environmental Protection Agency (EPA) could use cost-benefit analysis in setting standards for cooling water intake structures under Section 316(b) of the Clean Water Act. The EPA had established regulations that allowed facilities to choose among several compliance options, considering both environmental benefits and costs. Riverkeeper, Inc., an environmental group, challenged these rules arguing that they did not adequately protect aquatic life as mandated by law. The Supreme Court ruled in favor of Utility Water Act Group and other industry respondents, holding that the EPA's interpretation allowing cost-benefit analysis was reasonable under Chevron deference principles. This decision affirmed the agency’s discretion to weigh economic factors against environmental impacts when determining technology-based standards.

Dissent summary

Etalia.ai summary of the dissenting opinions

Justice Stevens, joined by Justices Souter and Ginsburg, dissented in the case. The dissent argued that the Environmental Protection Agency (EPA) should prioritize environmental protection over cost considerations when setting standards for cooling water intake structures under Section 316(b) of the Clean Water Act. Justice Stevens contended that Congress intended to protect aquatic life from industrial harm without allowing economic factors to undermine this goal. He criticized the majority's interpretation as inconsistent with both statutory text and legislative history, which emphasized minimizing adverse environmental impact rather than balancing it against costs. The dissent expressed concern that permitting cost-benefit analysis could lead to weaker protections for aquatic ecosystems and potentially allow industry interests to override ecological preservation mandates.
