How Army Corps of Engineers v. Kansas City Southern Railway Co. applies in Pennsylvania: state-specific rules, key cases, and bar exam notes for Environmental Law.
Pennsylvania law, particularly under the Pennsylvania Clean Streams Law and the Pennsylvania Sewage Facilities Act, closely aligns with the principles established in Army Corps of Engineers v. Kansas City Southern Railway Co., particularly regarding the jurisdiction of federal and state regulatory agencies over navigable waters. States retain the right to regulate environmental impacts through state-specific criteria that may extend beyond federal regulations.
In Pennsylvania, the rule acknowledges the primacy of state law in regulating waters and their uses, ensuring compliance with both state and federal standards, while examining the extent of federal jurisdiction under the Clean Water Act.
The Pennsylvania Supreme Court held that the state must adhere to stricter environmental protections as outlined in its constitution and applicable statutes.
The Commonwealth Court ruled that the Pennsylvania Department of Environmental Protection has wide authority to regulate pollutants impacting state waters, reinforcing state control consistent with Army Corps principles.
The court held that Pennsylvania's regulatory framework could impose more rigorous standards than federal law when protecting navigable waters.
While federal law under the Clean Water Act establishes significant jurisdiction over navigable waters, Pennsylvania's approach allows for more stringent state regulations, which can lead to enhanced protections. This reflects the larger principle highlighted in Army Corps of Engineers, where federal jurisdiction does not preempt state authority to regulate environmental impacts.
Practicing attorneys in Pennsylvania should be aware of how state environmental laws can impose additional duties beyond federal requirements, a key concept likely to appear in bar exam questions.
