The proposed bill would update current statutes by mandating the Director of the Department of Environmental Quality (ADEQ) to evaluate specific gasoline blends using the latest air emissions modeling approved by the U.S. Environmental Protection Agency (EPA). This evaluation, which must be completed within 210 days of the general effective date, will encompass various gasoline formulations, including federal phase II reformulated gasoline and California phase 3 reformulated gasoline. The bill also appropriates $100,000 from the state General Fund for this evaluation and requires the findings to be published on ADEQ's website, along with a report submitted to key state officials.

Additionally, the bill introduces a feasibility study to be conducted by the Associate Director of the Arizona Department of Agriculture (AZDA) within 90 days of receiving the ADEQ report. This study will evaluate the potential for authorizing gasoline blends identified in the ADEQ report that are not currently approved for sale in certain areas. The bill includes provisions for confidentiality regarding supplier information and allocates an additional $100,000 from the state General Fund for the feasibility study. Both the air emissions modeling reporting requirements and the fuel blend feasibility study are set to be repealed on October 1, 2027, ensuring a structured timeline for these initiatives.
