Background 

The U.S. environmental permitting process has long received criticism for lengthy permitting timelines that can stretch across several years, causing uncertainty for construction developers and affected stakeholders. These challenges have become more acute as demand for energy and manufacturing infrastructure has surged, especially due to advancements in artificial intelligence and increased usage of data centers. 

In July 2025, House Natural Resources Committee Chairman Bruce Westerman (R-AR) and Representative Jared Golden (D-ME) introduced the Standardizing Permitting and Expediting Economic Development (SPEED) Act to update how the National Environmental Policy Act (NEPA) governs federal project reviews. The House passed an amended version with a 221-196 vote on December 18, 2025, reflecting bipartisan recognition that federal permitting rules may need streamlining. The Act must pass in the Senate and be signed into law by the President to be enacted. This brief provides a nonpartisan overview of what the SPEED Act would change in how the federal government reviews major infrastructure projects, why it has attracted bipartisan support, and the concerns raised about its effects on environmental safeguards and community input.

What is NEPA?

The National Environmental Policy Act (NEPA), signed into law in 1970, is a foundational federal environmental law that governs how the U.S. government evaluates the environmental impacts of major actions, such as infrastructural projects. NEPA does not directly tell agencies what decision to make; instead, it requires them to carefully assess and disclose the potential environmental effects of significant federal actions—such as approving highway projects, energy infrastructure, or other major permits—and to consider alternatives before moving forward.

In practice, NEPA review happens at three main levels. Some actions qualify for a categorical exclusion (CATEX), meaning they are deemed not to have significant environmental effects and can proceed with minimal review. Many projects undergo an Environmental Assessment (EA) to decide whether the impacts are significant; if they are not, the agency issues a “Finding of No Significant Impact.” For projects that may have substantial effects, agencies prepare a full Environmental Impact Statement (EIS), which is a detailed study that typically includes public comment, input from other agencies, and analysis of different alternatives. EIS reviews are often lengthy and complex, and on average have taken several years to complete, which is one reason NEPA has become central to current debates over how quickly the United States can build new energy and infrastructure projects.

Whether an impact is considered “significant” is not determined by a single formula. Agencies generally evaluate the context and intensity of a project’s effects, including possible impacts on land, water, air, wildlife, public health, cultural resources, and nearby communities. They may also consider whether those effects are cumulative, uncertain, or difficult to reverse. 

What Is The SPEED Act?

The Standardizing Permitting and Expediting Economic Development (SPEED) Act is a bipartisan bill introduced on July 25, 2025. It is intended to change how NEPA is implemented in federal proceedings, with the aim of shortening and standardizing environmental review timelines. 

The bill concentrates on three changes: tightening NEPA procedures, expanding when projects can qualify for categorical exclusions from detailed review, and adjusting how courts review agency decisions. It clarifies that NEPA is a procedural statute, meaning it sets rules for how agencies must make decisions, not what decisions they must make. The bill would also encourage courts to defer more to agency judgments about the scope and level of detail in reviews, and give agencies more flexibility to rely on existing analyses rather than commissioning new studies. Lastly, the SPEED Act would not eliminate environmental review under NEPA, but rather change how that review is carried out in several ways: 

These changes would still be carried out through normal agency procedures and could still be challenged in court, but the bill would give agencies more leeway in deciding how much environmental analysis is enough, while making courts less likely to overturn those decisions.

How the SPEED Act Would Change Environmental Review?

These changes have led to different views about what the SPEED Act would mean in practice. Supporters argue that focusing reviews on impacts that are closely tied to the project and within an agency’s authority would make analyses more targeted and reduce duplication. They also contend that clearer deadlines and expanded categorical exclusions would help move lower-risk and already-studied projects through the process more quickly. From this perspective, environmental review remains in place, but becomes more predictable and effective for both agencies and project sponsors.

In contrast, critics worry that the same provisions could weaken the depth and breadth of environmental review. Narrowing the scope of analysis and relying more heavily on categorical exclusions, in their view, may increase the risk that cumulative, indirect, or community-level impacts are overlooked. Limits on incorporating new research and greater judicial deference to agency judgments could also make it harder for affected communities and outside experts to challenge decisions or ensure that reviews reflect the most current information. Some argue that by concentrating on NEPA procedures rather than on other bottlenecks, such as upgrading or redesigning electrical grids and facilities, the SPEED Act would do little to accelerate clean energy projects while making it easier for more polluting or controversial projects to advance with less scrutiny. In this perspective, the SPEED Act does not remove NEPA, but it may tilt the balance toward faster approvals and away from more expansive, precautionary review.

Why Is Permitting Reform On The Agenda Now?

In recent years, interest in permitting reform has grown as federal, state, and local governments have sought to expand energy, manufacturing, and infrastructure projects. The increased adoption of artificial intelligence and data centers, efforts to reshore industrial production, and the broader electrification of transportation and buildings have all added pressure on the energy system. Meeting this demand while keeping energy reliable and affordable has led many policymakers in both parties to focus on how quickly new projects can be reviewed and built.

At the same time, several legal and legislative developments have reshaped the permitting landscape. 

The Fiscal Responsibility Act of 2023 made targeted changes to NEPA, including some new timelines and clarifications. However, it did not resolve broader debates over the scope of environmental review and the role of courts in reviewing agency decisions—issues the SPEED Act seeks to address more directly. In 2025, the Supreme Court’s unanimous decision in Seven County Infrastructure Coalition v. Eagle County emphasized that NEPA is a procedural statute and signaled that courts should generally defer to agencies on the level of detail and the boundaries of environmental analysis. Against this legal backdrop, proposals like the SPEED Act are part of a broader, ongoing effort in Congress to decide how to balance faster project approvals with opportunities for public participation and environmental review.

Conclusion

The debate over the SPEED Act centers on how to balance faster, more predictable permitting with thorough environmental review. Because the SPEED Act applies broadly to federally-reviewed infrastructure rather than to one specific energy source, its ultimate effects will depend on how agencies put it into practice, how courts interpret it, and what kinds of projects are proposed and funded in the years ahead. At this point, however, there are not yet notable examples of the Act in operation because it has not completed the legislative process and is still pending in the Senate.
