In a brief ceremony yesterday, President Trump signed an Executive Order requiring EPA and the U.S. Army Corps of Engineers to review the final “Clean Water Rule,” also known as the  Waters of the United States (WOTUS) Rule to ensure it is consistent with a new policy also laid out in the order to keep the Nation’s navigable waters free from pollution “while at the same time promoting economic growth, minimizing regulatory uncertainty, and showing due regard for the roles played by Congress and the States under the Constitution.”  Although implementation of the Rule has been stayed by the U.S. Court of Appeals for the Sixth Circuit pending further court review, the Executive Order also requires EPA and the Corps to review all orders, rules, regulations, guidelines, or policies implementing the Rule and to revise or rescind such rules consistent with the Executive Order.

Revising or rescinding the Rule administratively is subject to the same notice and comment rulemaking procedures that EPA and the Corps followed when adopting the Rule, so the Executive Order is the first step in a lengthier 12-18 month administrative process.  In revising the Rule, the Executive Order requires EPA and the Corps to interpret “navigable waters” consistent with the late Justice Scalia’s plurality opinion in Rapanos v. U.S., in which Justice Scalia took the view that “navigable waters” meant waters that are “relatively permanent, standing or continuously flowing bodies of water ‘forming geographic features’ that are described in ordinary parlance as ‘streams[,] … oceans, rivers, [and] lakes.’” Rapanos v. U.S., 547 U.S. 715, 719 (2006) (citing Webster’s Dictionary).  Given this charge, EPA and the Corps are likely to craft a much more narrowly tailored rule than the existing Rule which relies largely on hydrologic connection or “significant nexus” to waters of the United States to allow EPA and the Corps to assert jurisdiction over a broader scope of waters.

The Order also requires Administrator Pruitt and the Assistant Secretary to the Corps to notify the Attorney General that the Rule is under review so that the Attorney General “as he deems appropriate” may inform the many courts with pending appeals of the rulemaking, including the Sixth Circuit and the United States Supreme Court.
