State of Ohio v. U.S. Army Corps of Engineers — Study Notes

990 F.3d 522 (6th Cir. 2020)

Study notes for State of Ohio v. U.S. Army Corps of Engineers: professor notes, cold call prep, exam angles, and memory aids.

The U.S. Army Corps of Engineers has jurisdiction under the CWA over intrastate, non-navigable waters that have a significant nexus to navigable waters.
Professor Notes

This case highlights the complexities of jurisdiction under the Clean Water Act (CWA), particularly regarding non-navigable waters. The Sixth Circuit articulated the rationale behind the significant nexus test, emphasizing that intrastate waters can affect navigable waters and, by extension, interstate commerce. Professors may underscore the implications of federal jurisdiction delineated in the CWA, as well as the ongoing debate regarding state versus federal authority over water resources. The decision underscores the need for states to recognize federal interpretations while navigating their regulatory frameworks.

Distinguish From
CaseDistinction
Rapanos v. United StatesRapanos involved a more direct examination of what constitutes a significant nexus, particularly emphasizing the divide between federal and state jurisdiction.
SWANCC v. U.S. Army Corps of EngineersSWANCC determined that isolated waters could not be regulated solely based on their potential to affect interstate commerce, which is a narrower interpretation than the significant nexus established in this case.
United States v. LarkinsLarkins dealt with the enforcement of CWA jurisdiction over wetlands, highlighting the reach of the Corps compared to more isolated waters as examined in Ohio v. Corps.
Policy Arguments

For the Rule

The ruling supports comprehensive federal regulation to protect water quality and ecosystems that are interconnected, thereby enhancing the environmental stewardship beyond state borders.

Against the Rule

The ruling may encroach upon state rights and freedom, potentially leading to federal overreach in local water management decisions, which could undermine state regulatory efforts.

Class Discussion Points
  • What are the implications of this ruling for state environmental law frameworks?
  • How does the significant nexus test redefine the boundaries of federal jurisdiction under the CWA?
  • Compare the challenges faced by states when federal interpretations shift—what does this mean for local governance?
  • Explore the role of scientific evidence in establishing the significant nexus in this and similar cases.
  • Debate the balance of power and regulatory authority between federal and state agencies over environmental resources.
Exam Angle

This case may appear on exams focusing on the jurisdiction of federal agencies and the interpretation of the Clean Water Act, particularly in defining the scope of 'waters of the United States.' Students should be able to analyze the significant nexus standard.
