The U.S. Army Corps of Engineers Regulatory Mission

The Corps of Engineers has been regulating activities in the nation’s waters since 1890.

Congress has enacted laws to regulate water resource development which are enforced by federal agencies including the Corps. These laws ensure that water resource development is consistent with the needs and welfare of the people.

Under Section 10 of the Rivers and Harbors Act of 1899 (33 USC 403), a permit is required for construction of any structure in or over any navigable water of the United States, or the accomplishment of any other work affecting the course, location, condition, or physical capacity of such waters.

Under Section 404 of the Clean Water Act of 1972(33 USC 1344), a permit is required to excavate in or discharge dredged or fill material into the Waters of the United States.

The list of Individual Permits finalized and pending for the Regulatory Program can be found at this link.

The U.S. Army Corps of Engineers (USACE) announced today that it received a final biological opinion from National Oceanic and Atmospheric Administration (NOAA) Fisheries on the nationwide permits that were reissued on Feb. 13, 2012, and went into effect on March 19, 2012. The biological opinion was issued on Nov. 24, 2014, and it concludes the re-initiated programmatic consultation on the Endangered Species Act that began in July 2012 between USACE and NOAA Fisheries. This biological opinion replaces NOAA Fisheries’ earlier biological opinion issued in February 2012. The biological opinion affects 19 of the 38 USACE districts. The St. Louis District is not affected since it does not have any coastal waters within its boundaries.Information on the 2012 nationwide permits, including the biological opinion dated Nov. 24, 2014, is posted to the USACE Web site at http://www.usace.army.mil/Missions/CivilWorks/RegulatoryProgramandPermits/NationwidePermits.aspx
The 2014 NWPL has been published on the NWPL website and the updated list contains 8057 plant species, an increase of 120 species, based on new literature. The majority of these new species received FACU ratings. The bulk of the 2014 update is the additional ratings for 754 species that were noted to occur in other areas of the 10 Corps Regional Supplement regions, based on the literature and herbarium records. All of these species were already included on the NWPL and only the new occurrences were rated. The 2014 update includes no nomenclature or taxonomic changes. Overall, these revisions represent a less than one percent change in species and ratings from the 2013 NWPL. Many of those plants that were updated are uncommon.  A summary of all the changes can be found on the NWPL website under the “What’s New?” section.

The 2013 update to the National Wetland Plant List was necessary to align with the current taxonomy and nomenclature of the Biota of North America (BONAP).  The update also addresses the results of interagency regional panel re-evaluations for 12 plant indicator statuses performed since the original 2012 NWPL was published.

The NWPL database is now managed on the Corps web server and future updates can occur more frequently (annually). 

The 2013 update reduces the total number of plants from 8200 to 7937 and reflect a 1.2% change in indicator statuses.  Please look for the lists of 2013 changes under the "What's New" section of the NWPL homepage.

The effective date for the 2013 NWPL is set for 1 September 2013.
