Senate Advances Nuclear Fuel Bill As Trump Orders Diesel Tax Relief

Washington is pursuing two separate approaches to strengthening America’s energy supply: a bipartisan Senate bill aimed at expanding domestic uranium enrichment and a presidential order intended to ease immediate diesel costs.

The MORE American Fuel Act cleared the Senate with an amendment by unanimous consent on September 30. Sponsored by Sen. Mark Kelly, D-Ariz., and backed by Sen. Cynthia Lummis, R-Wyo., the legislation now heads to the House.

President Donald Trump’s October 5 executive order addresses a different problem, directing federal officials to pursue temporary tax relief and suspend specified penalties involving highway use of red-dyed diesel.

Together, the measures reflect concerns about energy affordability and dependence on foreign supplies. Their mechanisms, timelines and legal status, however, differ substantially.

The Senate legislation concerns enriched uranium used in nuclear power generation. It would amend licensing provisions in the Atomic Energy Act to bring the process for uranium enrichment facilities into closer alignment with other nuclear fuel-cycle facilities.

Supporters say existing requirements force developers to wait years for a construction license before starting work, delaying investment in American enrichment capacity.

Under the proposal, companies could begin construction at their own financial risk once the Nuclear Regulatory Commission formally dockets an application.

That earlier start would not guarantee authorization to operate. Developers would assume the risk of spending money on construction before securing the necessary operating approval.

According to Kelly’s office, the NRC would retain control over operating licenses and safety standards. Environmental review and opportunities for public participation would also remain in place.

Companies would have to provide advance written notice to state, local and Tribal governments before construction begins.

The bill’s supporters argue that this approach could reduce delays while preserving regulatory oversight. Its significance extends beyond permitting procedures to the question of how much nuclear fuel America can supply for itself.

Lummis’ office says American operators import roughly 80 percent of their enriched uranium, leaving them vulnerable to price fluctuations abroad. Supporters also cite national security concerns surrounding reliance on overseas suppliers, including Russia.

Expanding domestic enrichment could reduce that exposure, but the legislation has additional hurdles. House passage is still required, and the Senate vote alone does not change existing law.

Trump’s diesel order, meanwhile, targets costs already weighing on farmers, truckers and other businesses.

Red-dyed diesel is generally associated with off-road equipment, including machinery used in agriculture and construction. The order seeks to make that fuel temporarily more available for highway use as elevated diesel prices increase the expense of moving goods.

It directs the IRS to suspend specified penalties for highway sales or use of red-dyed diesel from October 5 through the end of 2026.

Separately, the order instructs Treasury to consider deferring certain federal diesel tax payments through December 31. That relief depends on Treasury determining that existing law authorizes it.

The distinction between postponing a payment and eliminating it is important for businesses assessing the benefit.

Trump’s order requires Treasury to identify when deferred taxes would eventually become due. It also directs officials to explore ways to eliminate those obligations, including through legislation.

A tax deferral therefore should not be treated as a permanent tax cut. The final obligations will depend on Treasury’s implementation and any subsequent action to cancel them.

The order also calls for cooperation with states and continued enforcement of highway safety requirements.

Its immediate value to fuel buyers will depend on how quickly officials issue guidance, how broadly eligible diesel becomes available and whether savings are passed through to customers.

For businesses facing high transportation expenses, temporary access to additional fuel supplies and payment flexibility could offer relief. Neither provision, however, establishes a guaranteed reduction at the pump.

The two initiatives address different weaknesses in America’s energy system. The nuclear bill seeks to shorten the path toward greater domestic production, while the diesel order focuses on near-term supply and cost pressures.

Both will require follow-through. House lawmakers must decide whether to advance the uranium enrichment proposal, and Treasury must clarify the scope, eligibility and repayment terms of any diesel tax deferral.

Those next steps will determine whether Washington’s latest energy measures translate into more American production and meaningful relief for fuel users.
