On 18 January 2023 the United States Army Corps of Engineers’ and the Environmental Protection Agency’s Revised Definition of “Waters of the United States” was published in Federal Register Vol. 88, No. 11. The Final Rule, which defines what waters are protected by/subject to the Clean Water Act (CWA), becomes effective nationally on 20 March 2023. As stated in the summary: In developing this rule, the agencies considered the text of the relevant provisions of the Clean Water Act and the statute as a whole, the scientific record, relevant Supreme Court case law, and the agencies’ experience and technical expertise after more than 45 years of implementing the longstanding pre-2015 regulations defining “waters of the United States.” 

As previously announced, NAEP has been awaiting the formal publication of the Final Rule since fall 2022 and, as planned, will now host a webinar led by a panel of experts that will provide an informative and concise summary of the WOTUS definition’s technical, legal, and regulatory history. More importantly, they will analyze and discuss both the technical differences between the Final Rule and the current, pre-2015 WOTUS definition and the impact on the regulated community that is likely to result. The Final Rule’s effect on the natural resource the CWA was created to protect will also be considered, along with the potential impacts of the SCOTUS’ Sackett v. EPA opinion, which is anticipated to be delivered this spring.

NAEP has selected three expert panelists to summarize the Final Rule’s meaning, from the perspectives of the updated WOTUS’ technical definition, its changes to federal regulatory oversight, as well as the likely litigative entanglements that are certain to quickly follow. 

The panelists will provide their insight, which has evolved from decades of wide-ranging professional WOTUS experience. Collectively, on behalf of the public, private and regulatory sectors, they have mapped and documented the location and extent of WOTUS in the field, permitted WOTUS impacts in the office, and litigated disputed interpretations of both in the courtroom for over half a century. While the initial portion of the webinar will be a Final Rule summary, the latter portion will be an open discussion, with registrant participation not only encouraged, but expected. 

Please join NAEP for this timely and informative event, focused on how the soon-to-be-implemented changes to one of the United States’ most significant environmental regulations may impact the nation.
