U.S. Army Corps of Engineers Finalizes Modifications to Nationwide Permit Program

January 15, 2021

On January 13, 2021, the U.S. Army Corps of Engineers’ (ACOE) rule reissuing and modifying twelve existing Nationwide Permits (NWPs) and issuing four new NWPs was published in the Federal Register (Final Rule).[1] ACOE issues NWPs to authorize activities under Section 404 of the Clean Water Act and Section 10 of the Rivers and Harbors Act of 1899 (Section 10), where those activities are similar in nature and will result in no more than minimal adverse environmental impacts to aquatic resources separately or on a cumulative basis.

Most notably, the Final Rule splits the existing NWP 12 (previously referred to as “Utility Line Activities”) into three separate NWPs covering different types of utility lines: (1) the modified NWP 12 is limited to oil or natural gas pipeline activities; (2) the new NWP 57 authorizes electric utility line and telecommunications activities; and (3) the new NWP 58 authorizes utility line activities for water and other substances. The Final Rule provides that this change to existing NWP 12 is partly in response to recent litigation regarding oil and natural gas pipelines.  Issuing separate new NWPs for electric, telecommunication, and water lines is intended to provide a greater degree of certainty for the regulated communities that construct and maintain those types of utility lines in the event NWP 12 is invalidated or stayed by a federal court.[2]

Pre-construction notification (PCN) requirements for NWPs 12, 57, and 58 are streamlined in the Final Rule.  PCN requirements for NWP 12 will be triggered where: (1) a Section 10 permit is required; (2) the discharge will result in the loss of greater than 1/10-acre of waters of the United States; or (3) the proposed oil or natural gas pipeline activity is associated with an overall project that is greater than 250 miles in length and the project purpose is to install new pipeline along the majority of the distance of the overall project length.[3]  PCN requirements for new NWPs 57 and 58 will be triggered where: (1) a Section 10 permit is required; or (2) the discharge will result in the loss of greater than 1/10-acre of waters of the United States.

Another modification contained in the Final Rule involves existing NWP 51 (Land-Based Renewable Energy Generation Facilities) and NWP 52 (Water-Based Renewable Energy Generation Pilot Projects). The Final Rule removes the 300 linear foot limit for losses of stream bed and the provision authorizing the district engineer to waive the 300 linear foot limit for intermittent and ephemeral stream beds.[4] The waiver provision is no longer necessary as a result of the Navigable Waters Protection Rule, which took effect in June 2020 and excluded ephemeral streams from jurisdiction under the Clean Water Act.

The sixteen NWPs in the Final Rule go into effect March 15, 2021 and expire five years from that date. Generally, activities authorized by 2017 NWPs remain authorized by those NWPs until March 18, 2022, as long as the activities continue to comply with the terms and conditions of the twelve existing NWPs issued in the Final Rule. Activities authorized by 2017 NWPs that no longer qualify for authorization under any of the twelve existing NWPs that are reissued in the Final Rule continue to be authorized by the 2017 NWPs for twelve months following the Final Rule’s effective date, as long as those activities have commenced or are under contract to commence in reliance upon an NWP prior to the date on which the 2017 NWP expires.[5]
