Working in WOUS? Nationwide Permit Changes are Here!

The United States Army Corps of Engineers (USACE) just released the Nationwide Permits (NWP) with revisions to 12 existing NWPs and 4 brand new NWPs. These permits go into effect March 15, 2021. The new NWPs also includes 32 general conditions that will also apply to the permits.

NWPs enable the authorization of development projects in Waters of the United States (WOUS), including wetlands that have minimal environmental impacts. If additional impacts are anticipated, a Pre-Construction Notification (PCN) may be required. The benefits of the NWP include decreased review  and processing times. Having the NWP can allow your project to  begin more quickly. These NWPs are usually modified every five years, so the USACE is right on track. The one snag of NWPs is that it is the applicant’s responsibility to remain informed of changes, modifications, or revoked NWPs. However, fear not, as Hollaway will help you keep informed and keep your projects moving forward!

Hollaway Environmental + Communications Services reviewing permitsOn April 15, 2020, in a court case challenging the USACE’s 2017 NWP 12: Utility Lines, a federal district court of Montana understood the reissuance of this NWP as arbitrary and had violated the Endangered Species Act (ESA). As a result, this NWP was temporarily vacated and then reinstated in July of 2020. Therefore, one of the most anticipated changes is separating oil and gas pipeline activities from other utility activities such as transmission lines, power lines, and water lines. These actions now require a Section 10 Rivers and Harbors Act (RHA) permit to be included in these applications, as well as limitations on length in miles.

If you have any of the following NWP and have not completed the authorized work in jurisdictional WOUS (including wetlands), you may require a new permit authorization. The following permits have been modified and/or created:

  1. Oil or Natural Gas Pipeline Activities
  2. Surface Coal Mining Activities
  3. Residential Developments
  4. Commercial and Institutional Developments
  5. Agricultural Activities
  6. Recreational Facilities
  7. Stormwater Management Facilities
  8. Mining Activities
  9. Commercial Shellfish Mariculture Activities
  10. Underground Coal Mining Activities
  11. Land-Based Renewable Energy Generation Facilities
  12. Water-Based Renewable Energy Generation Pilot Projects
  13. Seaweed Mariculture Activities
  14. Finfish Mariculture Activities
  15. Electric Utility Line and Telecommunications Activities
  16. Utility Line Activities for Water and Other Substances
