Federal permitting for energy infrastructure is entering a more decentralized and discretionary era. Recent National Environmental Policy Act (NEPA) final rules from the U.S. Department of Agriculture (USDA) and Department of the Interior (DOI) show how federal agencies are moving away from a standardized review framework toward agency-specific permitting models intended to accelerate project approvals.
For project developers that have been navigating NEPA reviews for decades, this represents a significant shift. Federal agencies are now prioritizing speed, procedural flexibility and streamlined review pathways.
The next phase of NEPA implementation will be agency-specific
In early 2025, Executive Order 14154 directed federal agencies to eliminate delays within their permitting processes and to revise their NEPA implementing procedures. The Council on Environmental Quality (CEQ) followed up in February 2025 by nullifying its long-standing NEPA implementing regulations and requiring all federal agencies to update their individual NEPA rules within 12 months.
Without the CEQ framework agencies had relied on for decades, departments across the federal government started revising or replacing their internal NEPA procedures, shifting from binding CEQ regulations toward agency-specific guidance and handbooks.
The USDA and DOI are among the first agencies to finalize their updated procedures (April and February 2026), joining the Federal Energy Regulatory Commission. The USDA’s rule consolidated NEPA implementation across its diverse sub-agencies, including the U.S. Forest Service, the National Resources Conservation Service, and Rural Development.
These NEPA process developments are especially significant for the energy sector because agencies overseeing federal lands, transmission corridors, resource development and infrastructure approvals are in a position to critically reshape how projects move through environmental review.
The permitting landscape is evolving agency by agency. USDA and DOI’s final rules provide one of the clearest indications yet of how federal agencies intend to administer NEPA reviews going forward.
Greater efficiency may mean greater variability
While the latest federal NEPA updates are meant to drive more efficient reviews, this transition means we have replaced a relatively standardized national process framework with one that may vary significantly by lead agency, regional office, and/or project type.
We are already seeing that agencies are handling implementation differently. The DOI shifted much of its revised process into an internal handbook, while the Department of Housing and Urban Development largely depends upon an online portal for reporting and coordination, and the USDA formalized its NEPA procedures through rulemaking. Each of these strategies will create different opportunities and challenges for procedural flexibility over time.
Some NEPA components are likely to diverge across agencies include how categorical exclusions are applied and approved, the level of supporting analysis expected for environmental assessments, approaches to cumulative impacts, and the documentation required to support administrative records in litigation-prone jurisdictions. For projects involving multiple federal agencies, differences in NEPA process have the potential to create new coordination and sequencing challenges even where broader permitting timelines improve.
Facilitating stronger communication with agency leadership and developing trusted relationships with agency personnel will be critical to navigating these variations.
Faster reviews may not mean simpler permitting
Permitting timelines are a defining constraint of project delivery. For many energy and infrastructure projects, a substantially shorter federal review timeline is appealing.
Agencies now have greater flexibility to streamline reviews, reduce requirements for new data collection, and shorten delays tied to public comment periods. Combined with expanded lists of eligible categorical exclusions, some projects may now be able to move through NEPA documentation more efficiently than under previous frameworks.
Projects involving energy infrastructure, transmission development and federally supported critical infrastructure may also benefit from expanded use of accelerated or emergency review pathways.
These changes in NEPA implementation could improve permitting certainty and timeline confidence, particularly where reviews previously required extensive environmental analysis that depended on weather windows and resource-specific survey requirements.
The permitting process may become faster in some areas, but not necessarily simpler. Organizations will still need careful coordination and technical rigor, not less.
Defensible records still matter
Faster reviews don’t replace the need for strong technical records, particularly for projects that may face litigation risk or investor scrutiny. And, despite narrower review requirements, legal and reputational risks remain for a project team, and therefore, responsibility for additional due diligence and record keeping may shift from the lead federal agency to project developers.
This shift in responsibility may be particularly relevant for projects crossing federal, state and Tribal jurisdictions where environmental approval includes parties beyond the federal lead agency.
As a result, we recommend project developers take a more proactive role in maintaining clear technical documentation and a defensible administrative record throughout project development and review. The challenge will be balancing opportunities for faster approvals with the need to maintain consistency and defensibility and thus, long-term project resilience.

How energy organizations can adapt to the new permitting environment
The USDA and DOI actions signal that federal approval under NEPA has entered a new era. As the timeline above illustrates, federal agencies are not moving in lockstep. We expect NEPA reviews to continue to evolve, as departments refine implementation guidance, respond to litigation and adjust to future policy direction.
To navigate the revised NEPA landscape effectively, project owners should consider several practical steps:
- Reassess permitting strategies
Evaluate whether projects may now qualify for categorical exclusions or reduced levels of review under updated agency procedures. - Engage agencies early
Confirm which guidance documents, handbooks and internal procedures will govern project reviews moving forward and obtain federal lead agency buy-in on the use of available categorical exclusions (where applicable). - Maintain strong technical documentation
Streamlined reviews do not eliminate the need for clear environmental records that can withstand legal, stakeholder and investor scrutiny. - Account for state and lender expectations
Federal streamlining does not override state-level environmental review requirements or broader environmental, social and governance frameworks. - Coordinate multi-agency reviews carefully
Differences in how agencies interpret and apply their NEPA rules may still affect permitting schedules and project coordination. - Monitor ongoing procedural changes
Agency procedures may continue evolving through additional revisions, litigation or future policy direction.
Faster reviews will help many projects move forward more quickly. The challenge is making sure speed does not come at the expense of defensibility.
Organizations that adapt early while maintaining strong technical and administrative discipline will likely be better positioned to accelerate project delivery without increasing long-term permitting risk.
