ANKENY, IOWA (December 19, 2025) — The Iowa Biodiesel Board is urgently calling on the US Environmental Protection Agency to finalize the 2026-2027 Renewable Fuel Standard rule by January 31, 2025. The agency has said that any delay into February or March would push compliance to June, a move the IBB says would create a catastrophic gap that Iowa's independent, farmer-owned biodiesel plants may not be able to survive.
