1. New Definition of Waters of the United States
Has Been Released
On August 28, the EPA and the Corps released the pre-publication version of the revised definition of "Waters of the United States" to conform it to the definition set forth in the May 25 United States Supreme Court decision, Sackett v U.S. It is a direct final rule and will be effective immediately upon publication.
The revisions to the rule are very straightforward; “Waters of the United States” that are subject to regulation under the Clean Water Act has been revised to eliminate jurisdiction based on whether or not waters or wetlands “either alone or in combination with similarly situated waters in the region, significantly affect the chemical, physical, or biological integrity of” waters which are: (i) currently used, or were used in the past, or may be susceptible to use in interstate or foreign commerce, including all waters which are subject to the ebb and flow of the tide; (ii) the territorial seas; or (iii) interstate waters. Interstate wetlands are no longer jurisdictional, and wetlands “adjacent” to a jurisdictional water are jurisdictional only if they have a “continuous surface connection” to it; the revised rule replaces the prior definition of “adjacent” with this narrower definition.
The rule will likely be challenged by regulated interests on two points: (1) the lack of an exclusion for ditches and (2) the failure to define “adjacent” to add “and indistinguishable from”, which was a key point in the Sackett opinion. This omission could significantly broaden the reach of that term.
The following chart from the public fact sheet released by the EPA explains what has been revised in the rules, which can be found at 33 CFR s. 328.3 (Corps rule) and 40 CFR 120.2 (EPA rule):
