Broad statement of underlying support cannot sustain EPA regulatory definition of navigable waters [1]
EPA’s broad regulatory reach on navigable waters is rejected by the United States District Court for the District of Columbia.
Setting aside the EPA’s regulatory definition of navigable waters, the D.C. Circuit Court found the EPA’s definition was inadequately explained in light of recent United States Supreme Court cases. Oil producing facilities that add pollutants to navigable waters were required to develop spill prevention, control and counter measure plans under a Clean Water Act regulation that broadly defined navigable waters. Affected industry participants and associations successfully challenged the regulation.
The question became whether in promulgating a regulation in an area where there has been recent Supreme Court activity whether the EPA considered all the relevant factors. If it did not, plaintiffs argued the EPA’s decisions were arbitrary and capricious or a clear error of judgment. The EPA argued while concise, its explanation was adequate. Its explanation came in a response to a comment and provided in part: “The case law supports a broad definition of navigable waters, such as the one published today, and that definition does not necessarily depend on navigability in fact.”[2]
The court could not reconcile, however, recent cases, that do not define navigable waters as broadly as in the EPA’s expansive rule. Noting recent courts have reined in the reach of the definition of navigable waters to not reach the fullest extent of the commerce clause, the court found inadequate EPA’s brief comment statement. Thus, the court agreed the EPA rule was not the product of reasoned decision making and struck it.
