Today, the U.S. Environmental Protection Agency (EPA) and the U.S. Department of the Army (the agencies) announced a final rule establishing a durable definition of “waters of the United States” (WOTUS) to reduce uncertainty from changing regulatory definitions, protect people’s health, and support economic opportunity. The final rule restores essential water protections that were in place prior to 2015 under the Clean Water Act for traditional navigable waters, the territorial seas, interstate waters, as well as upstream water resources that significantly affect those waters. As a result, this action will strengthen fundamental protections for waters that are sources of drinking water while supporting agriculture, local economies, and downstream communities.  Click here visit the Corps Headquarters website for the press release and to access the rule and related materials.

The Regulatory Division of the U.S. Army Corps of Engineers, Charleston District is refining its process to emphasize review of Department of the Army (DA) permit applications and requests associated with pending DA permit applications beginning April 22, 2022. Requests not associated with a DA permit application, including standalone jurisdictional determinations (JDs) and delineation concurrences (DCs), will still be accepted, but the review and processing of such standalone requests will be based on available resources, resulting in extended timelines for processing. In-house wetland delineations conducted by the Corps will generally only be performed for small tracts (i.e., one acre or less) on a case-by-case basis and as time allows. For more, view the Public Notice and Process Refinement FAQs.

Other applications of the NWPL include wetland restoration, establishment, and enhancement projects. The list is effective as of 2 November 2021 and will be used in any wetland delineations performed after this date. Completed wetland delineation/determination forms should reference the version of the NWPL used to complete the form.  The final NWPL is available at (preferred browsers are Chrome and Firefox).
