2015 Waters of the U.S. Rule Repealed

UPDATE, October 22, 2019: The U.S. Army Corps of Engineers and the U.S. Environmental Protection Agency issued the Final Rule on this day. The Rule will be effective 60 days from the date of issuance, December 23, 2019.

The U.S. Environmental Protection Agency (EPA) and the Department of the Army have announced that they intend to repeal the 2015 Clean Water Rule and return the United States to the 1986 definition of Waters of the U.S. They plan to publish a Final Rule in the Federal Register soon¹, and have made a pre-publication version available; the policy will be effective 60 days after publication, likely mid-November 2019. The Trump administration’s February 2018 repeal of the 2015 Clean Water Rule was suspended in 26 states last August, including Virginia and Maryland. This Final Rule publication will have implications for those 26 states; the other 24 – where the repeal has been in place since February 2018 – will see no changes. A reversion of the definition from the 2015 Rule to the 1986 definition has little impact in Virginia or Maryland, however the implications are significant for some other parts of the United States.

The agencies began this process in response to the Trump administration’s February 28, 2017 Executive Order 13778, Restoring the Rule of Law, Federalism, and Economic Growth by Reviewing the `Waters of the United States’ Rule. They first published their intent to rescind the 2015 Rule in a proposed rule on July 27, 2017. This is the final piece of Step One in the administration’s two step plan to revise the Waters of the U.S. definition. Step Two started December 11, 2018 with the publication of a proposed new definition for the Waters of the U.S.
