SB1064 is a bill that seeks to diversify the gasoline fuel reformulation options available in Arizona, particularly for counties with populations of 1,200,000 or more. It introduces new standards for gasoline, including Federal Phase II, California Phase 3 reformulated gasoline, and other EPA-approved blends, while also setting seasonal production and shipment standards. The bill mandates that the Arizona Department of Environmental Quality (ADEQ) must obtain U.S. EPA approval for these modifications by July 1, 2025, or secure approval for iso-butanol as a gasoline ingredient. It allows for resubmission of non-rejected formulations if initially rejected by the EPA and includes provisions for handling fuel shortages and protecting certain communications from public record.

The bill also revises the process for obtaining waivers from motor fuel standards due to shortages, removing the previous option for registered suppliers or oxygenate blenders to petition for alternative compliance and instead allowing any person to petition for a waiver. It requires the posting of approved gasoline formulations online, mandates the use of the latest air emissions model for evaluating gasoline blends, and establishes a task force to study fuel supply issues in Arizona. The bill sets forth criteria for new gasoline blends to be considered for use in the state and requires a report on the feasibility of these blends to be submitted within 120 days of completing the necessary assessments. This section of the bill will be repealed on September 30, 2026.
