On January 15, 2026, the Environmental Protection Agency (EPA) published the long-awaited proposed rule Updating the Water Quality Certification Regulations (Proposed Rule), which, if adopted, would largely reinstate the previous Trump administration’s 2020 Clean Water Act Section 401 Certification Rule (2020 Rule). EPA’s proposal seeks to limit the scope of state-issued water quality certifications (WQCs) under Section 401 of the Clean Water Act (CWA) to water quality impacts associated with discharges authorized by federal agency actions. The Proposed Rule also addresses concerns raised by applicants for federal licenses and permits (including for hydroelectric projects, natural gas pipelines, and other energy and infrastructure projects) that certain states have overstepped their Section 401 authority to impose onerous terms and conditions unrelated to water quality and artificially extended the statutory time limits for issuing WQCs.

On November 20, 2025, FERC terminated several long-pending rulemaking and policy dockets in an effort to provide “regulatory certainty.”  Specifically, FERC closed RM22-20, RM18-10, RM20-7, and PL20-7.

RM22-20 proposed requiring that any entity communicating with FERC or other specified organizations related to a matter subject to FERC’s jurisdiction submit accurate…

On November 20, 2025, FERC took several steps aimed at finalizing oil pipeline price index levels for the July 1, 2021, to June 30, 2026, time period (“2021-2026 Period”). First, FERC set the oil pipeline index level for the 2021-2026 Period at PP-FG+0.78% (“Initial Index”), consistent with the index level it originally set in December 2020. FERC also issued remedial relief through a rehearing order to applicable oil pipelines for the March 1, 2022, to September 17, 2024, time period in which an index level of PPI-FG-0.21% (“Rehearing Index”) was in effect. The relief ordered by FERC will allow qualifying pipeline to recover amounts they would have otherwise charged under the Initial Index while the Rehearing Index prices were in effect. Finally, FERC withdrew a Supplemental Notice of Proposed Rulemaking (“Supplemental NOPR”) in which FERC sought to proactively set the Rehearing Index as the index level for the remainder of the 2021-2026 Period.

On October 7, 2025, FERC rescinded the regulation that precluded natural gas pipeline companies from receiving authorization to proceed with construction of their new projects during the period for filing requests for rehearing of certificate orders, or while rehearing is pending. In doing so, FERC stated that its rescission will…

On October 1, 2025, the Federal Energy Regulatory Commission issued a final rule revising 53 regulations to include conditional sunset provision in response to the April 2025 Executive Order titled “Zero-Based Regulatory Budgeting to Unleash American Energy.” FERC, along with nine other agencies, was required to establish one-year…

On June 18, 2025, FERC temporarily raised the cost limits for blanket certificate natural gas pipeline projects constructed and placed into service by May 31, 2027, from $41 million to $61.65 million. Citing what it called a pressing nationwide near-term demand for expanded natural gas transportation capacity and reliability concerns…

On May 29, the Supreme Court issued a unanimous opinion in Seven County Infrastructure Coalition v. Eagle County, Colorado that dramatically changes the way courts scrutinize federal agencies’ environmental reviews under the National Environmental Policy Act (NEPA). Justice Brett Kavanaugh, writing for a five-justice conservative majority (with Justice Neil Gorsuch abstaining), held that (a) courts must afford federal agencies “substantial judicial deference” regarding both the scope and contents of their environmental analyses; and (b) courts do not need to consider the effects of the action to the extent they are “separate in time or place” from the proposed project. The ruling gives federal agencies permission to greatly streamline their NEPA analyses at a time when those agencies are rapidly being drained of their resources and facing increasing pressure to expedite lengthy permitting processes.

On September 12, 2024, FERC’s Chief Accountant issued a notice of proposed accounting release (“NOPAR”) to modify the transferability of income tax credits (“ITCs”) related to certain energy projects under the Inflation Reduction Act of 2022 (“IRA”), which allows entities to monetize such ITCs via transfers to independent third parties…

On September 10 and 11, 2024, FERC staff held a two-day workshop at its headquarters in Washington, DC on opportunities to further refine the generator interconnection queue process. Panelists and FERC staff discussed potential enhancements to transmission planning and processing interconnection requests over the course of six panels on discrete…

On July 9, 2024, the United States Court of Appeals for the District of Columbia Circuit (“D.C. Circuit”) declined to stay a new Environmental Protection Agency (“EPA”) rule that seeks to limit methane emissions in the oil and gas industries (“Methane Rule”), thereby allowing the Methane Rule to remain in effect while litigation proceeds.
