Senate Permitting Bill Sets 150-Day Lawsuit Window and Permit Certainty Rules

The leaders of two Senate committees have released the text of a bipartisan federal permitting bill, the American Affordability and Jobs Act of 2026, that would shorten the window for lawsuits against project approvals to 150 days, limit the government's ability to pull permits it has already issued and give federal regulators more authority to site interstate power lines. The bill was introduced on September 30, 2026 by Sens. Shelley Moore Capito, Mike Lee, Sheldon Whitehouse and Martin Heinrich, according to the Senate EPW Committee.

Congress has been circling permitting reform for several years, and the House passed its own version in December. What is different this time is that the Senate text was negotiated with the White House and carries the names of the chair and ranking member of both committees with jurisdiction, ENR reported. A floor vote is planned for shortly after the November 3 midterm elections ENR.

What Happened

Capito, a West Virginia Republican, chairs the Environment and Public Works Committee, and Whitehouse, a Rhode Island Democrat, is its ranking member. Lee, a Utah Republican, chairs the Energy and Natural Resources Committee, and Heinrich, a New Mexico Democrat, is its ranking member ENR.

The sponsors framed the bill around cost and delivery speed. Lee said the country "once built projects like the Hoover Dam, the Golden Gate Bridge, and the Empire State Building in years, not decades" Senate EPW Committee. Heinrich said it "should not take decades to build the infrastructure our country needs" Senate EPW Committee. Whitehouse said Americans want lower energy bills and more clean energy and that the plan "gets us a long way toward both" Senate EPW Committee.

The committee summary describes the bill as providing permit certainty for energy and infrastructure projects, reforming environmental review and permitting, making targeted energy project changes, setting transmission cost requirements for data centers and protecting tribal consultation and environmental safeguards Senate EPW Committee.

What Is in the Bill

The text is organized in two divisions, one for each committee, according to an analysis by Holland & Knight. The provisions most relevant to builders are below.

Environmental Review and Litigation

• 150-day litigation window. Challenges to environmental reviews under the National Environmental Policy Act would have to be filed within 150 days Holland & Knight. Similar 150-day periods would apply to challenges of specified Clean Water Act Section 404 actions, Endangered Species Act biological opinions, covered energy, mining and forest management authorizations, and National Historic Preservation Act decisions Holland & Knight.
• Remand over vacatur. When a court finds a deficiency in a review, the bill favors sending it back to the agency to fix instead of vacating the permit Holland & Knight.
• NEPA is procedural. The text clarifies that NEPA governs process and does not mandate a particular outcome, and it extends the useful life of programmatic reviews from five years to 10 Holland & Knight.
• Parallel consultations. Endangered Species Act Section 7 consultations would have to conclude by the time the NEPA document is complete, and a new historic preservation consultation would run concurrently with NEPA under defined time limits Holland & Knight ENR.

Clean Water Act Permits

• National Pollutant Discharge Elimination System permit terms would double from five years to 10, as would Section 404 general permits Holland & Knight.
• Section 401 water quality certifications for interstate transmission lines and pipelines would face a maximum deadline of nine months, and the scope of Section 401 review would be narrowed to applicable water quality requirements Holland & Knight.
• The Environmental Protection Agency would be barred from preemptively or retroactively removing lands from Clean Water Act certification, a provision ENR lists among those sought by Democrats.

Permit Certainty

This title is aimed at a risk that has unsettled owners and lenders: a federal approval being withdrawn after a project is financed or under construction. The bill would restrict the rescission, suspension or material alteration of permits after September 16, 2026 Holland & Knight. It would set a one-year deadline for decisions on energy and natural resource authorizations that do not require an environmental assessment or impact statement Holland & Knight.

It would also give applicants a way to enforce those rules. Available remedies include reinstatement, attorneys' fees, delay costs and damages, and courts could act on improper delays and patterns of disparate treatment Holland & Knight. The title covers renewable and conventional generation, nuclear, transmission, pipelines, mining, storage and carbon management Holland & Knight.

Transmission and Data Center Load

The Federal Energy Regulatory Commission would get expanded backstop authority to site interstate transmission without first requiring a national interest corridor designation, and it would serve as lead agency for NEPA review on covered projects Holland & Knight. Transmission applications could be processed at the same time as state reviews, and regional and interregional planning would have to account for future electricity demand ENR.

The bill directs FERC to revise pricing for large computational loads and creates separate state-level protections for data center loads of 20 megawatts or more Holland & Knight. Qualifying grid upgrades inside existing rights-of-way would be streamlined Holland & Knight.

Other Provisions

The energy title sets deadlines and categorical exclusions for renewable projects, and includes geothermal and hydropower licensing changes Holland & Knight. The bill authorizes $150 million a year from fiscal 2027 through 2031 for endangered species consultations and $200 million a year for the Historic Preservation Fund through fiscal 2036 Holland & Knight. It also creates a fund for cleanup of abandoned hardrock mines ENR.

Where Things Stand

The Senate recessed the evening the bill was introduced, and a cloture vote on the motion to proceed is scheduled for November 9, 2026 Holland & Knight. ENR reported that senators plan to take up a manager's amendment shortly after the election.

The House passed its SPEED Act in December 2025, so the two chambers would still have to reconcile their versions ENR. We covered that bill when it passed, in our post on the House SPEED Act. Open questions include whether the White House will support faster permitting for renewable projects and whether House Democrats will seek more leverage after the election ENR.

Reaction was mixed but mostly favorable from industry. Mike Sommers of the American Petroleum Institute called it a "generational" opportunity to modernize NEPA, while Sara Chieffo of the League of Conservation Voters called it "significant and complex legislation" that needs further analysis ENR.

Even if enacted, much of the practical effect would depend on later rulemakings by FERC, the Council on Environmental Quality, the Interior Department and EPA Holland & Knight.

Implications for Owners, Developers, Contractors and Subs

Owners and developers of projects with a federal permit, federal funding or a federal land or water nexus would gain the most from the litigation and certainty provisions. A fixed 150-day window makes it possible to tell a lender when the legal risk on an approval ends Holland & Knight. The restriction on altering issued permits, with damages and delay costs as a remedy, addresses the scenario of a stop-work order arriving mid-construction Holland & Knight.

Industrial and site developers should note the 10-year terms for discharge permits and Section 404 general permits Holland & Knight. Longer terms reduce how often an operating plant or a phased site has to return for renewal.

Contractors on linear and utility work would see the most direct schedule effect from the nine-month cap on Section 401 certifications for interstate lines and pipelines and from FERC's expanded siting role Holland & Knight.

Data center owners and their builders should watch the 20-megawatt threshold and the pricing directive, which could change how transmission costs are assigned to large loads Holland & Knight.

Subcontractors will not see anything change on a job this year. This is a bill, not a law, and its benefits would arrive through agency rules over a period of years Holland & Knight.

What to Watch

• The November 9 cloture vote and the contents of the manager's amendment Holland & Knight ENR.
• Negotiations with the House over differences with the SPEED Act ENR.
• Whether the September 16, 2026 date in the permit certainty title survives Holland & Knight.
• Agency rulemaking schedules if the bill is enacted Holland & Knight.

Bottom Line

This is the most complete bipartisan permitting text the Senate has produced, and it targets the two things that most affect project finance: how long an approval can be challenged and whether it can be taken back Holland & Knight. It still has to clear the Senate floor and be reconciled with the House ENR. Owners with federally permitted work in the pipeline should follow the November vote closely and avoid building schedules around provisions that are not yet law.
