>WOTUS Plan - Waters of the United States
Revised Definition of "Waters of the United States" - Proposed Rule
On December 11, 2018, the EPA and Department of the Army proposed a clear, understandable, and implementable definition of "waters of the United States" that clarifies federal authority under the Clean Water Act. The agencies’ proposal is the second step in a two-step process to review and revise the definition of “waters of the United States” consistent with the February 2017 Presidential Executive Order entitled “Restoring the Rule of Law, Federalism, and Economic Growth by Reviewing the ‘Waters of the United States’ Rule.” The proposed definition would replace the approach in the 2015 Rule and the pre-2015 regulations.
