EPA draft biofuel blend mandate expected Friday: Update

EPA draft biofuel blend mandate expected Friday: Update

Updates with changes throughout New York, 12 June (Argus) — President Donald Trump's administration plans to release draft biofuel blend mandates for 2026 and 2027 on Friday, according to three people familiar with the matter. The draft quotas, in addition to a separate final rule cutting cellulosic biofuel mandates for last year, exited White House interagency review on Wednesday, the last step before major regulations can be released. The Trump administration has meetings with legislative stakeholders on Friday morning ahead of the public release, three people said. Previously scheduled meetings through the end of the month as part of the interagency review process appear to have been cancelled, another signal that the rules' release is imminent. The Environmental Protection Agency (EPA) has said it wants to get the frequently delayed Renewable Fuel Standard program back on its statutory timeline, which would require volumes for 2027 to be finalized before November this year. Any proposal will have to go through the typical public comment process and could be changed. EPA said the rules will be posted on its website once they are signed by Lee Zeldin, the agency's administrator. A coalition of biofuel-producing groups and feedstock suppliers, including the American Petroleum Institute, has pushed EPA to set a biomass-based diesel mandate of 5.25bn USG for 2026, hoping that a record-high target will support biorefineries that have struggled this year. Many plants have idled or run less recently, as uncertainty about future blend mandates, the halting rollout of a new clean fuel tax credit, and tariffs that up feedstock costs all hurt margins. US senator Chuck Grassley (R-Iowa) said Thursday that closed biodiesel plants in his state needed a 5.25bn mandate to reopen. Meanwhile, a coalition of independent and small refiners that have long lamented the costs of the program wrote to EPA this week asking for less-aspirational future mandates, including for the conventional category mostly met by corn ethanol. RIN markets were volatile today, trading higher in the morning before slipping lower on fears the mandates would not meet industry expectations. Current year ethanol D6 RINs traded as high as 99¢/RIN before falling as low as 90¢/RIN. Current year biomass-based diesel D4 RINs ended Thursday at 102.5¢/RIN, equal to their close the prior day. Small refinery exemptions loom Zeldin told a House subcommittee last month the agency wanted "to get caught up as quickly as we can" on a backlog of small refiner requests for program exemptions. Courts took issue with EPA's exemption policy during Trump's first term and again during President Joe Biden's tenure, leaving officials now with dozens of waiver requests covering 10 compliance years still pending. It is unclear whether the rule will provide much clarity on EPA's plans for program waivers, but biofuel groups have worried that widespread exemptions would curb demand for their products. The price of Renewable Identification Number (RIN) credits used for program compliance have been volatile this year on rumors about these exemptions, which EPA has called market manipulation. In both the Trump and Biden administrations, EPA estimated future exempted volumes when calculating the percentage of biofuels individual refiners had to blend, effectively requiring those with obligations to shoulder more of the burden to meet high-level volume targets. The agency could continue that approach, but it would be more legally treacherous for the agency to similarly "reallocate" exempted volumes from past years into future standards, lawyers said. EPA by law also has to consult on exemption decisions with the Department of Energy, which a person familiar said was "still going through the scoring process" for assessing some small refinery applications, making quick resolution of the issue unlikely. Unresolved court cases, including a Supreme Court case about the proper venue for small refinery waiver disputes, could also give regulators pause until they know more. Tax credit clarity expected soon Senate committees this week have been releasing their versions of key parts of the major Republican spending bill, and the Senate Finance Committee is expected to do so soon, potentially as early as Friday according to people familiar. The incentive is crucial for biofuel production margins and thus for the viability of EPA mandates too. The version that passed the House last month would extend the "45Z" clean fuel production credit through 2031, bar regulators from considering indirect land use emissions, and restrict eligibility to fuels from North American feedstocks. While various ideas have circulated this year, lobbyists expect the Senate to preserve the general structure of the credit, which throttles benefits based on carbon intensity, rather than reinvent a new subsidy. Still, some Republicans have expressed concern with the House's phaseout of tax credit "transferability", which benefits smaller companies without much tax liability. And major oil refiners with renewable diesel plants reliant on Asian used cooking oil and South American tallow have lobbied for more flexibility around foreign feedstocks. Any changes that up the credit's costs could be controversial too among conservatives worried about the bill's impacts on a mounting federal budget deficit. And the complex tax credit will ultimately need final regulations from the US Department of Treasury clarifying eligibility. At a Senate hearing Thursday, Treasury secretary Scott Bessent said that the Trump administration planned to implement the credit in a way to "not allow for foreign actors to have a back door into the program."
