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.
The proposed rule published in the Federal Register on February 14, 2019. The public comment period closed on April 15, 2019. Comments are being posted to Docket ID No. EPA-HQ-OW-2018-0149 and are available here in the docket.You may need a PDF reader to view some of the files on this page.
