Here are the new COE /EPA guidlines. I think these are way beyond what the Court had in mind. They are far less than what is in the Bill CB1 pointed out.
June 5, 2007 Clean Water Act Jurisdiction
Clean Water Act Jurisdiction
Following the U.S. Supreme Court’s Decision
in
Rapanos v. United States & Carabell v. United States
This memorandum provides guidance to EPA regions and U.S. Army Corps of
Engineers ["Corps"] districts implementing the Supreme Court’s decision in the
consolidated cases Rapanos v. United States and Carabell v. United States1 (herein
referred to simply as "Rapanos") which address the jurisdiction over waters of the United
States under the Clean Water Act.2 The chart below summarizes the key points contained
in this memorandum. This reference tool is not a substitute for the more complete
discussion of issues and guidance furnished throughout the memorandum.
1 126 S. Ct. 2208 (2006).
2 33 U.S.C. §1251 et seq.
Summary of Key Points
The agencies will assert jurisdiction over the following waters:
• Traditional navigable waters
• Wetlands adjacent to traditional navigable waters
• Non-navigable tributaries of traditional navigable waters that are relatively permanent
where the tributaries typically flow year-round or have continuous flow at least
seasonally (e.g., typically three months)
• Wetlands that directly abut such tributaries
The agencies will decide jurisdiction over the following waters based on a fact-specific analysis to
determine whether they have a significant nexus with a traditional navigable water:
• Non-navigable tributaries that are not relatively permanent
• Wetlands adjacent to non-navigable tributaries that are not relatively permanent
• Wetlands adjacent to but that do not directly abut a relatively permanent non-navigable
tributary
The agencies generally will not assert jurisdiction over the following features:
• Swales or erosional features (e.g., gullies, small washes characterized by low volume,
infrequent, or short duration flow)
• Ditches (including roadside ditches) excavated wholly in and draining only uplands and
that do not carry a relatively permanent flow of water
The agencies will apply the significant nexus standard as follows:
• A significant nexus analysis will assess the flow characteristics and functions of the
tributary itself and the functions performed by all wetlands adjacent to the tributary to
determine if they significantly affect the chemical, physical and biological integrity of
downstream traditional navigable waters
• Significant nexus includes consideration of hydrologic and ecologic factors
