What did the EPA decide regarding Delek's and HF Sinclair's 2024 biofuel blending exemption requests?

The EPA granted Delek US Holdings' Alon Refining Krotz Springs refinery a full exemption from federal biofuel blending requirements for 2024, while declaring HF Sinclair's hardship waiver petitions for its Artesia, New Mexico refinery ineligible for both 2023 and 2024 because the facility exceeded the 75,000 barrel-per-day crude throughput limit required to qualify as a small refinery under the Renewable Fuel Standard (RFS).

Why did the EPA reject HF Sinclair's exemption petitions?

The EPA rejected HF Sinclair's petitions for its Artesia refinery for the 2023 and 2024 compliance years because the facility exceeded the 75,000 barrel-per-day crude throughput threshold, disqualifying it from small refinery status—and thus eligibility—for economic hardship exemptions under the Renewable Fuel Standard (RFS) regulations.
