Commonwealth of Pennsylvania, Department of Environmental Protection v. U.S. Army Corps of Engineers, 866 F.3d 231 (3rd Cir. 2008)
The case of Commonwealth of Pennsylvania v. U.S.
Does the U.S. Army Corps of Engineers have to comply with state-issued permits under the Clean Water Act when conducting federal projects, or does federal sovereignty negate these requirements?
Under the Clean Water Act, federal agencies are generally required to comply with applicable state environmental permitting processes, unless there is a clear statutory or executive exclusion.
The court held that the U.S. Army Corps of Engineers must comply with state permitting requirements as stipulated under the Clean Water Act, unless explicitly exempted by federal law.
This case is pivotal for law students interested in environmental law and federalism, as it delineates the boundaries of state and federal power in environmental regulation. It serves as a precedent illustrating the balance of power and the necessity for federal projects to respect state environmental laws, reinforcing state autonomy in environmental governance.
