Today Gov. Gary Herbert joined Marathon Petroleum Corporation and its Speedway gas stations in celebrating Marathon’s Utah Refinery’s recent conversion toTier 3 fuel production.
26 Speedway gas stations across Utah will begin selling Tier 3 gas on January 1.
With this multi-million dollar investment and conversion, Marathon is leading the way on critical investments to improve Utah’s air quality. A few years ago, during a board meeting with the refinery board and leadership, Gov. Herbert had the opportunity to discuss his vision for improving Utah air and the production of Tier 3 fuels.
