Definition of “Waters of the United States”-Recodification of Preexisting Rule
The purpose of this supplemental notice is for the Environmental Protection Agency (EPA) and the Department of the Army (agencies) to clarify, supplement and seek additional comment on an earlier proposal, published on July 27, 2017, to repeal the 2015 Rule Defining Waters of the United States (``2015 Rule''), which amended portions of the Code of Federal Regulations (CFR). As stated in the agencies' July 27, 2017 Notice of Proposed Rulemaking (NPRM), the agencies propose to repeal the 2015 Rule and restore the regulatory text that existed prior to the 2015 Rule, as informed by guidance in effect at that time. If this proposal is finalized, the regulations defining the scope of federal Clean Water Act (CWA) jurisdiction would be those portions of the CFR as they existed before the amendments promulgated in the 2015 Rule. Those preexisting regulatory definitions are the ones that the agencies are currently implementing in light of the agencies' final rule published on February 6, 2018, adding a February 6, 2020 applicability date to the 2015 Rule, as well as judicial decisions preliminarily enjoining and staying the 2015 Rule.
