On February 19, 2026, the Federal Energy Regulatory Commission (FERC) issued a notice of proposed rulemaking that would expand an existing National Environmental Policy Act (NEPA) categorical exclusion to cover certain terminations and revocations of hydropower licenses and exemptions. The proposal would allow FERC to rely on a categorical exclusion, rather than preparing an Environmental Assessment (EA) or Environmental Impact Statement (EIS), for license and exemption terminations or revocations that involve only minor or no ground-disturbing activity and minor or no changes in reservoir conditions and downstream flows.

On January 22, 2026, the Federal Energy Regulatory Commission (Commission or FERC) issued a 40‑year original license to FFP Project 101, LLC (FFP) to construct and operate a 1,200‑megawatt pumped storage hydropower facility, the Goldendale Energy Storage Project, in Klickitat County, Washington. FERC found that, with conditions, the closed‑loop pumped storage project will add significant long‑duration capacity and flexibility to help integrate renewable resources in the Western grid.

On December 29, 2025, FERC terminated the hydropower license for the 0.9-megawatt Au Train Hydroelectric Project (FERC Project No. 10856), located on the Au Train River in Alger County, Michigan (Termination Order). FERC concluded that termination of the license by “implied surrender” was warranted because the project’s licensee, UP Hydro, LLC (UP Hydro), had abandoned good-faith operation of the project through years of safety violations, loss of control over project lands, and financial collapse. The order ends more than two decades of federal oversight over the project and transfers regulatory authority to the State of Michigan to oversee the decommissioning of the dam.

The U.S. Court of Appeals for the D.C. Circuit on May 16, 2025, clarified the conditions under which a state waives its Clean Water Act (CWA) Section 401 water quality certification (WQC) authority. In Village of Morrisville v. Federal Energy Regulatory Commission, the D.C. Circuit rejected arguments by a hydropower licensee that Vermont waived its certification authority under Section 401 by failing to issue a WQC within one year from receipt of a certification request. The applicant unilaterally withdrew and refiled its WQC application twice in an effort to avoid unfavorable certification conditions. Because the applicant withdrew its WQC application to further its own interests, the court held that the applicant could not claim that Vermont waived its Section 401 conditioning authority by not issuing a WQC within a year from the original application.

On January 14, 2025, the U.S. Court of Appeals for the D.C. Circuit (“D.C. Circuit”) held that FERC complied with the National Environmental Policy Act (“NEPA”) in approving the surrender of a hydroelectric project license. The court found that FERC had adequately considered the alternative of dam removal and determined that keeping the dams in place outweighed any potential benefits to recreation, fisheries, and other environmental concerns. The case, American Whitewater v. FERC, involved a challenge to FERC’s license surrender decision regarding the Somersworth Hydroelectric Project (“Project”) on the Salmon Falls River, which spans the border between New Hampshire and Maine.

On November 21, 2024, the Federal Energy Regulatory Commission (“FERC”) issued a final rule establishing a categorical one-year “reasonable period of time” for certifying authorities to act on requests for water quality certification under section 401 of the Clean Water Act (“CWA”). The final rule also clarifies that all FERC authorizations “that have the potential to discharge into waters of the United States,” including hydropower exemptions, amendments, and surrenders, require either a section 401 water quality certification or waiver thereof.

We are pleased to announce the release of our latest whitepaper, Fueling Up: How to Make U.S. Clean Hydrogen Projects Happen. This comprehensive report explores the critical steps needed to unlock the potential of clean hydrogen in the U.S., and the related challenges faced by developers and utilities.

At its May 23, 2024 open meeting, the Federal Energy Regulatory Commission (“FERC”) issued a Notice of Proposed Rulemaking (“NOPR”) proposing to establish a one-year “reasonable period of time” for certifying authorities to act on requests for water quality certification under section 401 of the Clean Water Act (“CWA”).  The proposed rule also clarifies that all FERC authorizations “that have the potential to discharge into waters of the United States,” including exemptions from licensing, require either a section 401 water quality certification or waiver thereof.

At the February 15, 2024, FERC open meeting and in four orders issued the same day, FERC established a new policy governing its issuance of preliminary permits under section 4(f) of the Federal Power Act (“FPA”), pursuant to which it will not issue preliminary permits for projects located on Tribal lands if the Tribe on whose land the project is proposed to be located opposes the permit. FERC explained that this policy change is based on the agency’s commitment to ensuring that Tribal concerns and interests are considered whenever FERC’s actions or decisions have the potential to adversely affect Tribes or Tribal trust resources. To avoid future permit denials, FERC emphasized that potential applicants should fully inform Tribes about proposed projects on their lands before filing the permit application.

On April 21, 2023, the President Biden issued an “Executive Order on Revitalizing Our Nation’s Commitment to Environmental Justice for All.” The new Executive Order provides that “each [federal] agency should make achieving environmental justice part of its mission.” To that end, it provides that agencies shall:
