petition; waiver; fuel formulations

HB 2145 requires gasoline sold in Arizona counties with over 1.2 million residents (Area A) to meet either federal Phase II or California Phase 2 reformulated fuel standards, excluding minimum oxygen content rules. It allows fuel suppliers to petition for temporary waivers during imminent ethanol shortages, demonstrating supply issues and proposing alternative oxygenate blends that maintain approximately 3.5% oxygen content. The petition must specify affected suppliers, blend details, and a 60-day compliance period, with decisions made within 7 days by state officials. This bill directly affects gasoline suppliers and blenders in designated high-population areas, aiming to balance environmental standards with supply chain flexibility.
