Case Brief Summary & Legal Analysis
tl;dr: The court reviewed EPA rules for lead in drinking water, upholding the agency’s interpretation of ambiguous statutory terms under Chevron deference but vacating a rule defining “control” over water lines for failing the APA’s “logical outgrowth” test for notice and comment.
Legal Significance: This case exemplifies the application of Chevron deference to an agency’s technical judgments and clarifies the “logical outgrowth” test, requiring that a final rule be reasonably foreseeable from the notice of proposed rulemaking to satisfy APA requirements.

Case Facts & Court Holding
Key Facts & Case Background
The Environmental Protection Agency (EPA), acting under the Safe Drinking Water Act (SDWA), promulgated a final rule to regulate lead in public drinking water. Due to the difficulty of measuring lead levels, which primarily leach from privately-owned plumbing rather than the water source, the EPA opted for a “treatment technique” instead of a Maximum Contaminant Level (MCL). The rule also required public water systems to replace lead service lines they “control.” The Notice of Proposed Rulemaking (NPRM) had discussed a rebuttable presumption that a water system “owns or controls” lines up to the building wall. However, the final rule defined “control” much more broadly, creating a presumption of control if the system had ownership, authority to replace or repair the line, or merely the authority to set standards for the line’s construction, repair, or maintenance. The American Water Works Association (AWWA) challenged this definition, arguing it was not foreshadowed in the NPRM, thus violating the notice-and-comment requirements of the Administrative Procedure Act (APA). The Natural Resources Defense Council (NRDC) challenged the EPA’s decision to use a treatment technique instead of an MCL.
Court Holding & Legal Precedent
Issue: Did the Environmental Protection Agency act permissibly under the Safe Drinking Water Act and the Administrative Procedure Act when it (1) chose a treatment technique over a maximum contaminant level for lead, and (2) promulgated a final rule defining a water system’s ‘control’ over service lines in a manner significantly broader than what was described in the proposed rule?
Yes, in part, and no, in part. The court held that the Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
