Alaska v. U.S. Army Corps of Engineers, 941 F.3d 1072 (9th Cir. 2019)
The case of Alaska v. U.S.
Does the U.S. Army Corps of Engineers have jurisdiction under the Clean Water Act over the specific wetlands in Alaska given their connection to a historically navigable waterway?
Under the Clean Water Act, the term 'waters of the United States' encompasses traditional navigable waters as well as adjacent wetlands if there is a significant nexus to navigable waters, meaning the wetlands significantly affect the chemical, physical, and biological integrity of those waters.
The Ninth Circuit Court held that the U.S. Army Corps of Engineers did have jurisdiction over the Alaskan wetlands in question, as they retained a significant nexus to navigable waters, thus falling under the definition of 'waters of the United States' under the Clean Water Act.
This case is significant because it reinforces the application of the significant nexus test in Clean Water Act jurisprudence, impacting how wetlands are regulated federally. It illustrates the balance between state sovereignty and federal responsibilities in natural resource management and highlights the legal intricacies involved in environmental regulatory frameworks. For law students, it presents a practical example of how case law evolves in response to ecological and jurisdictional realities, particularly the balancing act between environmental conservation and developmental interests.
