HOT INFO

The Army Corps has incorporated preventative measures due to the COVID-19 pandemic at its Regulatory Program offices to minimize potential exposure of Corps personnel, permit applicants and the general public, including limiting some day-to-day operations and postponing Corps-hosted events, office meetings and public engagements. Regulatory staff continue to process/evaluate permit applications and materials, conduct phone conferences, host or participate in virtual meetings and respond to inquiries by email and telephone. Field visits have been limited to a case-by-case basis. Click here for additional details.

Regulatory Overview

The mission of the U.S. Army Corps of Engineers Regulatory Program is to protect the Nation's aquatic resources while allowing reasonable development through fair, flexible and balanced permit decisions.  The Corps has been regulating activities in the nation's waters since 1890. The program was initially created solely to prevent obstructions to navigation, although an early 20th century law gave the Corps regulatory authority over the dumping of trash and sewage. The passage of the Clean Water Act in 1972 greatly broadened this role by giving the Corps authority over dredging and filling in the "waters of the United States," including many wetlands.

June 10, 2019 - Draft biennial update to National Wetland Plant List for 2018 in Federal Register​
The U.S. Army Corps of Engineers, as part of an interagency effort with the U.S. Environmental Protection Agency, the U.S. Fish and Wildlife Service, and the U.S. Department of Agriculture - Natural Resources Conservation Service, announces the draft biennial update to the National Wetland Plant List (NWPL) for 2018 in the Federal Register. The Corps encourages public input in the form of data, comments, literature references or field experiences to help clarify the status of the species reviewed for this update, as well as public input on the NWPL process. The public will have the opportunity to comment on the proposed update or addition of wetland indicator status ratings for 20 plant species in select Corps wetland regions. These 20 reviewed species and their draft 2018 wetland ratings by region, as well as the FR notice, can be viewed at the NWPL homepage under “2018 NWPL Update Information.” A link to provide general or species-specific comments is also available at this location. Users are encouraged to submit literature citations, herbaria records, experiential references, monitoring data and other relevant information. Specific knowledge of, or studies related to, individual species are particularly helpful. Commenters should use their regional botanical and ecological expertise, field observations, reviews of the most recent indicator status information, appropriate botanical literature, floras, herbarium specimens with notation of habitat and associated species, habit data, relevant studies and historic list information. Guessing ratings is inappropriate. All submitted comments and information will be compiled and sent to the National Panel for their consideration.

The Corps is also seeking comments on the NWPL update process. Detailed information on the update process, protocol and technical issues can be found in the following documents (available on the NWPL Publications web page referenced above):

1) Lichvar, Robert W. and Minkin, Paul. Concepts and Procedures for Updating the National Wetland Plant List. Sept. 2008. ERDC/CRREL TN-08-3
