fuel formulations; waiver; posting; confidentiality

SB 1313 sets specific fuel standards for gasoline sold in Arizona's Area A (encompassing Maricopa County and parts of other counties with over 1.2 million residents). It requires gasoline to meet one of six defined formulations - based on federal or California air quality standards - during most of the year, with additional oxygen content rules from November to March. The bill includes a waiver process allowing gas suppliers to temporarily adjust fuel blends during verified ethanol shortages, subject to strict documentation and a 60-day limit. This directly affects gas stations and fuel suppliers operating in Area A by mandating compliance with these technical specifications.
