The U.S. Treasury plans to issue final regulations for the 45Z clean fuel production credit in November 2026, according to a July 3 regulatory agenda from the White House OMB. Proposed guidance was released in February with a public comment period ending in April and a hearing in May. The 45Z credit is a key incentive for low-carbon fuel production, including sustainable aviation fuel, renewable diesel, and other biofuels. The timeline gives producers and investors a clearer window for planning projects that depend on the credit's final structure. The same agenda shows USDA plans a July 2026 final rule updating the Biorefinery Loan Guarantee Program, which offers up to $250 million per project for new and emerging biofuel technologies. EPA is also expected to finalize its reconsideration of the Greenhouse Gas Reporting Program in July 2026, a move that could affect verification of CO2 sequestration data used for the 45Q carbon capture tax credit. Notably, the agenda does not mention 2028 Renewable Fuel Standard volume requirements, which must be set by late 2026 under statute. The missing RFS timeline may signal delays or internal disagreements at EPA.

Treasury targeting November for final 45Z rules. Proposed guidance came out in February, comment period closed in April, hearing in May. That timeline feels tight but at least there is a date on the calendar now. The missing RFS 2028 volumes in the same agenda is the bigger red flag for me.

The USDA loan program update is interesting too. Up to 250 million per project for biorefineries. If they actually streamline the application process that could unlock some real capacity. But the GHGRP repeal hanging over 45Q verification is still a mess.

November for final 45Z rules means producers have to wait another 4 months minimum. That delays investment decisions for SAF and renewable diesel plants. The missing RFS 2028 volumes in the agenda is a bigger concern though. Statutory deadline is late 2026 and EPA is not even listing it as active.

The GHGRP repeal timeline is also July 2026. If EPA kills the program, 45Q verification loses its main data source. Treasury issued backup guidance late last year but that is a workaround at best. The Iowa and Nebraska AGs want it voluntary instead of full repeal.

The missing RFS 2028 volumes in the agenda is the real story here. Statutory deadline is 14 months before compliance year, so late 2026. If EPA is not even listing it as active, that suggests either internal delays or a deliberate stall. That affects biodiesel and renewable diesel producers directly.

The USDA loan program update could matter for biorefinery retrofits. Up to 250 million per project is real money. But the article does not say what the revisions are. If they just tweak paperwork requirements that is one thing. If they change eligibility criteria that could shift which projects get built.
