Circle No. 7 v. Environmental Protection Agency, 918 F.3d 789 (9th Cir. 2023)
Circle No. 7 v.
Can the State of Summerland enforce more stringent water quality regulations than those established by the EPA under the Clean Water Act?
Under the Clean Water Act, while the EPA sets baseline national standards for pollutants, states are allowed to adopt and enforce more stringent standards as long as they do not conflict with federal law.
The court held that the State of Summerland is permitted to enforce its more stringent regulations, as they do not conflict with the purposes of the Clean Water Act but rather fulfill its objectives of maintaining and improving water quality.
This case is significant as it underscores the legal principle of cooperative federalism within the realm of environmental law. It affirms the states' ability to act as critical partners in environmental governance by adopting standards exceeding federal minimums, thus influencing policy and operational frameworks at the intersection of federal and state authority. For law students, it exemplifies the practical implications of federalism and the dynamic power balance in regulatory environments.
