Since publication of the rule in the Federal Register, numerous lawsuits were filed challenging the regulation, and several parties sought preliminary injunctions to delay implementation of the rule. On August 27, 2015, United States District Courts in Georgia and West Virginia agreed with the Agencies that legal challenges to the Rule could only be brought in the United States Court of Appeals for the 6th Circuit and therefore denied the requests for preliminary injunction. However, the District Court for North Dakota found that it had jurisdiction and granted the request of a number of States and issued a decision preliminarily enjoining the Clean Water Rule.
Under the order issued by the District Court of North Dakota, the parties that obtained the preliminary injunction are not subject to the new rule, and instead continue to be subject to the prior regulation. In light of the order, EPA and the Army Corps of Engineers will continue to implement the prior regulation in the following States: Alaska, Arizona, Arkansas, Colorado, Idaho, Missouri, Montana, Nebraska, Nevada, New Mexico, North Dakota, South Dakota, and Wyoming.
In all other States, the new Clean Water Rule is effective on August 28.
