Regulatory Branch

The Department of the Army Regulatory Program is one of the oldest in the Federal Government. Initially it served a fairly simple, straightforward purpose: to protect and maintain the navigable capacity of the nation's waters. Time, changing public needs, evolving policy, case law and new statutory mandates have changed the complexion of the program, adding to its breadth, complexity and authority.

The Regulatory Program is committed to protecting the Nation's aquatic resources, while allowing reasonable development through fair, flexible and balanced permit decisions. The Corps evaluates permit applications for essentially all construction activities in the Nation's waters, including wetlands.

Regulatory Announcement

The Environmental Protection Agency and the Department of the Army’s Navigable Waters Protection Rule (NWPR):  Definition of “Waters of the United States” became effective on June 22, 2020 in 49 states and all US territories. A preliminary injunction has been granted for the state of Colorado.  Federal jurisdiction in Colorado will be determined using the 2019 Rule (the recodification of the 1986 Regulations) and associated 2003/2008 (SWANCC/Rapanos) guidance documents.  The NWPR establishes the scope of federal regulatory authority under the Clean Water Act.  The NWPR includes four simple categories of jurisdictional waters and provides specific exclusions for many water features that traditionally have not been regulated. 

The Federal Register notice is available at https://www.federalregister.gov/documents/2020/04/21/2020-02500/the-navigable-waters-protection-rule-definition-of-waters-of-the-united-states.  Additional information about the rule can be found on the EPA’s website at https://www.epa.gov/nwpr.

The U.S. Army Corps of Engineers (Corps), as part of an interagency effort with the U.S. Environmental Protection Agency (EPA), the U.S. Fish and Wildlife Service (FWS) and the U.S. Department of Agriculture Natural Resources Conservation Service (NRCS), is announcing the availability of the final 2018 National Wetland Plant List (NWPL). The Federal Register Notice for the 2018 NWPL update can be found here: https://www.govinfo.gov/content/pkg/FR-2020-05-18/pdf/2020-10630.pdf.

The NWPL provides plant species indicator status ratings, which are used in determining whether the hydrophytic vegetation factor is met when conducting wetland delineations under the Clean Water Act and wetland determinations under the Wetland Conservation Provisions of the Food Security Act. Other applications of the NWPL include wetland restoration, establishment, and enhancement projects. The list is effective as of May 18, 2020 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 http://wetland-plants.usace.army.mil/.  State, regional, and national lists can also be downloaded from this site.

Beginning March 18, 2020, the USACE Omaha District’s Regulatory Branch began utilization of telework for all staff.  Telework will continue for an undetermined amount of time.  During this period Regulatory personnel will be working from home utilizing alternative technology to access work files and communicate via email.  Personnel have received guidance to evaluate risk involved with conducting local travel to perform site visits, and when asked to participate in interagency and applicant/consultant meetings.  They have also received direction to remain aware of and adhere to local/municipality and state proclamations regarding participation in gatherings and meetings and exercise flexibility in methods of participation for meetings that USACE normally hosts.

To ensure the continued delivery of the nation’s Regulatory Program, additional flexibility to standard requirements will be implemented.  Electronic submittals and signatures will be utilized when possible.  Also, virtual meeting capabilities, such as webinars or use of Skype, will be used in certain instances.   Applicants, resource agencies and the general public should continue to submit information via previously utilized methods such as mail, email and telephonic contact.  Please be aware that there will be limited to no personnel in any of the offices and the best form of contact at this time is via email.  We realize that this will impact all work products that are currently being evaluated by the Omaha District, but please understand that we are working to identify all strategies to make this impact minimal while doing our part to keep the public and our workforce safe.  This announcement will be periodically updated as procedures and strategies are identified and implemented as we work through these challenging times, so please check back regularly.
