EPA Power Diminished in Supreme Court Ruling

2 June 2023 – by Willy Phillips

This post covers the recent Supreme Court ruling which limits power of the EPA to regulate water pollution.

In a 5-4 decision last week, the Supreme Court of the United States ruled to limit the power of the Environmental Protection Agency (EPA) in policing water pollution via the Clean Water Act. This decision limits the power of the EPA to set regulations and has raised concerns about the potential risks to valuable ecosystems and national water quality.

The ruling, which stemmed from the Sackett V EPA case in Montana, has narrowed the EPA’s jurisdiction to regulate pollution in wetlands. According to the Supreme Court, the EPA overstepped its authority by expanding the “waters of the United States” definition under the Clean Water Act which was established over 50 years ago. The court’s majority opinion argued that the EPA’s broad interpretation of this term encompassed bodies of water that did not fall within the scope of federal regulation.

Wetlands play a crucial role in supporting diverse ecosystems, acting as natural filters for water, and providing habitat for numerous plant and animal species. This ruling has raised concerns that the reduced authority of the EPA to regulate wetlands could lead to increased pollution and degradation of these valuable ecosystems. Without robust federal oversight, wetlands and their associated ecosystems may be vulnerable to harmful practices such as industrial pollution and unregulated development.

The Supreme Court’s decision has created a fragmented regulatory framework across states. Unlike state lines, wetlands do not have clear borders. As a result, states may adopt varying standards and regulations, creating inconsistencies and gaps in environmental protection, further complicating national efforts to address pollution. Acting as a new precedent, more cases challenging EPA jurisdiction are sure to arise. 

Environmentalists and conservationists have expressed concern about the ruling, highlighting the potential consequences for water quality and biodiversity. They argue that wetlands are vital for maintaining the balance of ecosystems, protecting against floods, and supporting wildlife populations. Justice Elena Kagan led the dissenting opinion, stating the court has unjustly positioned itself as the “national decision-maker on environmental policy.” 

This decision highlights questions about the balance between environmental protection and property rights. Critics of expansive EPA regulations argue that they impose unnecessary burdens on landowners, limiting their ability to utilize their properties for economic purposes. Meanwhile, proponents of the regulations argue environmental matters are the responsibility of the EPA and not the Supreme Court. The ruling essentially reflects a judicial attempt to balance protecting the environment and respecting individual property rights, of which the implications are yet to be realized.
