Case Brief Summary & Legal Analysis
tl;dr: The Supreme Court upheld the EPA’s interpretation of the Clean Water Act, allowing it to grant “fundamentally different factor” (FDF) variances for toxic pollutants. The Court deferred to the agency’s reasonable construction of the ambiguous statutory term “modify,” finding it did not prohibit such variances.
Legal Significance: This case is a key application of Chevron deference, affirming an agency’s power to interpret ambiguous statutory language to create flexible regulatory mechanisms, even when a statute appears to impose a strict prohibition on modifying standards.

Case Facts & Court Holding
Key Facts & Case Background
The Clean Water Act (CWA) requires the Environmental Protection Agency (EPA) to establish uniform, technology-based effluent limitations for categories of industrial sources discharging pollutants. To account for atypical plants, the EPA created a “fundamentally different factor” (FDF) variance, allowing for case-by-case adjustments to the national standards where a facility’s characteristics are fundamentally different from those the EPA considered in setting the categorical rule. In 1977, Congress amended the CWA, adding § 301(l), which provides that the EPA “may not modify any requirement” of the section as it applies to toxic pollutants. The Natural Resources Defense Council (NRDC) challenged the EPA’s regulation authorizing FDF variances for toxic pollutants, arguing that § 301(l) constituted an absolute ban. The EPA contended that the term “modify” in § 301(l) referred only to specific statutory modifications based on economic or water-quality grounds (found in § 301(c) and § 301(g)), not to FDF variances. The EPA characterized FDF variances as a tool to refine its initial categorization, not as a substantive waiver of the applicable standard. The Third Circuit sided with the NRDC, and the Supreme Court granted certiorari.
Court Holding & Legal Precedent
Issue: Does § 301(l) of the Clean Water Act, which prohibits the EPA from “modifying” effluent limitations for toxic pollutants, unambiguously foreclose the EPA’s long-standing interpretation that it may grant “fundamentally different factor” (FDF) variances to individual sources?
No. The Court held that the EPA’s interpretation of § 301(l) to Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
