Study notes for Preamble v. EPA: professor notes, cold call prep, exam angles, and memory aids.

The EPA lacks the authority to expand the definition of 'waters of the United States' to include non-navigable waters under the Clean Water Act.
Professor Notes

Preamble v. EPA serves as a critical examination of the scope of federal regulatory authority under the Clean Water Act (CWA). The D.C. Circuit's ruling underscores the importance of maintaining a balance between federal and state jurisdiction over water resources. The court's interpretation of 'waters of the United States' highlights the limitations that Congress placed on EPA's authority, a theme central to environmental law that explores the extent of federal powers in regulating traditionally state-managed resources.

Moreover, the decision is significant in light of ongoing debates around environmental protection versus state rights. It demonstrates how the judiciary can act as an arbiter in disputes between different levels of government regarding environmental regulations. This case also poses broader implications for future environmental policy, suggesting that any attempt to regulate water resources must carefully consider both statutory authority and state interests.
