requiring that retailers of fuel blends with 15% ethanol also offer fuel blends with 10% or lower ethanol content.

HB 454 requires fuel retailers who sell 15% ethanol blends (like E15) to also offer at least one fuel blend with 10% ethanol or less (like E10). This applies to all such retailers in New Hampshire starting July 1, 2025. Retailers must display prices for these lower-ethanol blends as required by existing fuel pricing rules. The bill directly affects gas station operators selling higher-ethanol fuels, ensuring they provide more common ethanol blends for vehicle compatibility.
