  • Navigable Waters Protection Rule (NWPR)

    June 22, 2020 - The Environmental Protection Agency (EPA) and the Department of the Army’s Navigable Waters Protection Rule: Definition of “Waters of the United States” (NWPR) became effective in 49 states and in all US territories. A preliminary injunction (PI) was 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. Additional information about the NWPR can be found on the EPA’s website at https://www.epa.gov/nwpr. Information on jurisdiction can also be found at https://www.usace.army.mil/Missions/Civil-Works/Regulatory-Program-and-Permits/juris_info/.
  • Final 2018 National Wetland Plant List (NWPL)

    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.
