On Monday, the U.S. Court of Appeals for the Sixth Circuit concluded that it has jurisdiction to review challenges to the “Clean Water Rule.” As previously detailed on this blog, the Clean Water Rule was promulgated by the Environmental Protection Agency (EPA) and the Army Corps of Engineers to clarify and expand the reach of the Clean Water Act which is controlled by the phrase “waters of the United States.” But there has been intense opposition to the rule and it is now subject to more than 20 separate challenges filed by numerous states and interest groups. A number of these challenges were consolidated in the Sixth Circuit and in October, the Sixth Circuit stayed the rule nationwide, concluding that the challengers demonstrated a “substantial possibility of success.”

In yesterday’s decision, the Sixth Circuit panel concluded that it has jurisdiction to hear the consolidated challenges to the Clean Water Rule under Sixth Circuit precedent and 33 U.S.C. § 1369(b)(1) of the Clean Water Act. Unless the EPA or the Army Corps can obtain a hearing on this jurisdiction question before all of the Judges of the Sixth Circuit and/or it’s reviewed by the U.S. Supreme Court, and in either case, have the decision overturned, the Sixth Circuit will be the first court to decide the validity of the Clean Water Rule.
