US oil, farm groups push EPA for steep biofuel mandate

New York, 1 April (Argus) — The American Petroleum Institute and biofuel-supporting groups told Environmental Protection Agency (EPA) officials at a meeting today that the agency should sharply raise advanced biofuel blend mandates for 2026. The coalition told EPA that it supported a biomass-based diesel mandate next year of 5.25bn USG, up from 3.35bn USG this year, and a broader advanced biofuel mandate, including the cellulosic category, at 10bn Renewable Identification Number (RIN) credits, up from 7.33bn RINs this year, according to three different groups that attended the meeting. Both mandates would be record highs for the Renewable Fuel Standard (RFS) program. Soybean oil futures and RIN credit prices have risen sharply over the past week on optimism that oil and biofuel interests were working to coordinate volume mandate requests for consideration by President Donald Trump's administration. The coalition is also pushing the agency to set a total conventional volume requirement at 25bn RINs, which would keep an implied mandate for corn ethanol flat at 15bn USG. Ethanol groups had previously eyed a mandate even higher, but limits on the amount of ethanol that can be blended into gasoline make much more-stringent requirements a tough sell to oil refiners. The coalition provided no specific request for the cellulosic biofuel subcategory, where most credit generation comes from biogas. Credits in that category are more expensive, but price concerns have been less potent recently given an EPA proposal to lower previously set cellulosic obligations, signaling that future volume requirements can be cut, too. EPA is aiming to finalize new RFS volume mandates by the end of the year if not earlier, people familiar with the administration's thinking have said. EPA officials signaled at the meeting they were working urgently on the rulemaking. "The agency is intent on getting the RFS program back on the statutory timeline for issuing renewable volume obligation rules," EPA said, declining to comment further on its plans for the rule. The RFS program requires oil refiners and importers to blend biofuels into the conventional fuel supply or buy credits from those who do. Under the program's unique nesting structure, credits from blending lower-carbon biofuels can be used to meet obligations for other program categories. One gallon of corn ethanol generates 1 RIN, but more energy-dense fuels earn more RIN credits per gallon. Some disagreements persist While groups at the meeting were aligned around high-level mandates, how administration officials and courts treat small refinery requests for exemptions from RFS requirements could undercut those targets. Groups present were broadly aligned on asking EPA not to grant widespread exemptions, though there is still disagreement in the industry about how best to account for exempted volumes when deciding requirements for other refiners. Groups present at the meeting today included the American Petroleum Institute and representatives of biofuel producers and crop feedstock suppliers. Some groups that previously engaged with the coalition's efforts to project unity to the Trump administration were not present. And some groups more historically skeptical of the RFS and more supportive of small refinery exemptions — including the American Fuel and Petrochemical Manufacturers — have not been closely involved. Fuel marketer groups notably did not attend the meeting after a representative sparred with others in the coalition at an American Petroleum Institute meeting last month. Some retail groups, including the National Association of Convenience Stores and the National Association of Truck Stop Operators, instead sent a letter to EPA today arguing that the groups pushing steep volumes are discounting potential headwinds to the sector from new tax credit policy. Some of the groups advocating for higher biofuel volumes have pointed to high production capacity and feedstock availability, but have preferred to ignore thornier issues like tax credits, lobbyists say. "An overly aggressive increase in advanced biofuel blending mandates under the RFS will be punitive for American consumers" without extending a long-running $1/USG tax credit for biomass-based diesel blenders, the retailers' letter said. That incentive expired last year and was replaced by the Inflation Reduction Act's "45Z" credit, which offers subsidies to producers instead of blenders and throttles benefits based on carbon intensity. Generally lower credit values for biomass-based diesel — coupled with the US government's delays setting final regulations on qualifying for the credit — have spurred a sharp drop in biofuel production to start the year. Without a blenders credit, the RFS volume mandates pushed by some groups could increase retail diesel prices by 30¢/USG, the fuel marketers estimate, a potential political headache for a president that ran on curbing consumer costs. Other biofuel groups say that extending the credit would be an uphill battle this year, with some lawmakers and lobbyists instead focused on legislatively tweaking the 45Z incentive's rules to benefit crop feedstocks instead of reverting wholesale to the prior tax policy.
