Why is the Energy Department deleting a biofuel incentive program that never paid anyone?

The Department of Energy is erasing a regulation that has sat on the books for nearly two decades without ever sending a dollar to a producer. The rule takes effect on October 1, 2026 and removes 10 CFR Part 452 in its entirety.

A program that never launched

Congress created the Cellulosic Biofuels Production Incentive in the Energy Policy Act of 2005. Section 942 of that law, codified at 42 U.S.C. 16251, gave the Department of Energy authority to pay producers for every gallon of cellulosic biofuel they made. The department wrote the rules for how those payments would work. They live in 10 CFR Part 452. The rules describe a reverse auction. The lowest bidder would win the incentive. But Congress never appropriated the money. Not in 2005. Not in any year since. The program has never made a single payment. The regulatory framework has been dormant for its entire existence.

What the rule actually removes

The final rule published on September 1, 2026 deletes every section of 10 CFR Part 452. The part is marked "removed and reserved" in the Code of Federal Regulations. That means the text disappears but the part number stays empty for future use. The rule is four pages in the Federal Register. Pages 56001 through 56004. The effective date is October 1, 2026. The docket number is EERE-2025-OT-0031. The Regulatory Identifier Number is 1904-AG07. The Office of Critical Minerals and Energy Innovation signed the action. That office used to be called the Office of Energy Efficiency and Renewable Energy.

One comment

The department received one comment on the proposed rule. The commenter argued the rescission required a full environmental review under the National Environmental Policy Act. They said the categorical exclusion DOE planned to use was invalid because of uncertain environmental risks and potential cumulative impacts. DOE disagreed.

Why NEPA does not apply

On July 3, 2025 the department published an interim final rule revising 10 CFR Part 1021. Appendix A of that part now lists administrative and routine actions that do not require NEPA review. Paragraph A6 covers procedural rulemaking. DOE determined that removing the reverse auction requirements is strictly procedural. Therefore it falls under Appendix A paragraph A6. No environmental assessment or environmental impact statement is needed. The rescission of an inactive program with no ongoing environmental effects does not create new risks.

Where the incentives live now

The Renewable Fuel Standard program run by the Environmental Protection Agency has become the primary federal mechanism for renewable fuel incentives. That program uses Renewable Identification Numbers to track and credit production. Cellulosic biofuels qualify under the RFS. The EPA administers those credits. The DOE program was redundant before it ever started. The final rule classifies the action as an E.O. 14192 deregulatory action. The department says the primary impact is eliminating regulatory burden from an inactive program. Benefits are difficult to quantify but believed to be positive. The Regulatory Flexibility Act certification states the rule has no significant economic impact on a substantial number of small entities. No new information collection requirements are created. The Paperwork Reduction Act does not apply.
