Overview
- The EPA, which issued the emergency waiver Wednesday, set it for May 1–20 and said it can reissue the waiver to keep E15 and E10 available if supply problems persist.
- The action allows nationwide summer sales of E15, a 15% ethanol blend usually curbed because higher ethanol raises fuel volatility that can worsen ground-level ozone.
- Analysts say the shift may trim only a few cents per gallon even as industry groups tout 10–40 cent gaps, and AEI notes E15’s lower energy content reduces real-world savings with the U.S. average near $3.98, per AAA.
- Access is uneven with roughly 3,000 stations offering E15 mostly in the Midwest, and it is not approved for pre‑2001 cars, motorcycles, boats, or small engines.
- Farm groups cheered and urged Congress to make year‑round E15 permanent, while the White House paired the step with oil‑reserve releases and other supply moves to blunt Iran‑linked price spikes.
