Plain-English summary
Court says EPA may not issue permits that make permit holders responsible for waterbody quality
The Court held that EPA exceeded its authority under the Clean Water Act by approving permit language that effectively made permit holders responsible for meeting water-quality standards across an entire receiving water body. The judgment from the Ninth Circuit was reversed and the case remanded for further proceedings consistent with the opinion.
Why this matters
The decision clarifies the line between what EPA may require in pollution permits and what falls outside its authority under the Clean Water Act. It prevents EPA (and states that implement the Act) from using permits to shift responsibility for overall waterbody conditions onto individual permit holders, which affects how water quality enforcement, compliance planning, and permit drafting will work nationwide.
Who may feel it
- Municipalities and industrial facilities that hold NPDES discharge permits
- State environmental agencies that issue and approve CWA permits
- The U.S. Environmental Protection Agency (EPA)
- Communities and environmental groups concerned with water quality
- Businesses and small dischargers regulated under the Clean Water Act
Key questions
- Does the Clean Water Act allow EPA or authorized states to include permit terms that require a permittee to ensure the receiving water meets water-quality standards (so-called "end-result" provisions)?
