HB2014: Study on Gasoline Blends and Air Emissions

This bill gives money to two state agencies to test different types of gasoline blends for air pollution levels and study if they can be sold in Arizona.

What This Bill Does

• Requires the Department of Environmental Quality (ADEQ) to use federal models to evaluate five specific categories of gasoline blends for compliance with air emissions standards.
• Funds ADEQ with $100,000 from state money for fiscal year 2026-2027 to complete this evaluation and publish a report online.
• Requires the Arizona Department of Agriculture (AZDA) Weights and Measures Services Division to study if new gasoline blends found in the first step can be sold or used in Arizona.
• Funds AZDA with $100,000 from state money for fiscal year 2026-2027 to complete this feasibility study and publish a report online.
• Sets deadlines of 90 days after completing the modeling work for ADEQ to finish their report, and 90 days after receiving that report for AZDA to start its study.

Who It Names or Affects

• The Arizona Department of Environmental Quality (ADEQ)
• The Weights and Measures Services Division within the Arizona Department of Agriculture
• Registered suppliers and oxygenate blenders who provide information for the feasibility study

Terms To Know

Reformulated gasoline

A type of fuel blended to burn more cleanly than conventional gasoline to reduce smog-forming pollutants.

Area A and Area C

Specific parts of Arizona where special fuel standards apply based on population or location rules.

Air emissions modeling

Using computer tools approved by the EPA to predict how much pollution a specific gasoline blend will create.

Limits and Unknowns

• The bill only requires studies and reports; it does not immediately change which gas stations can sell which fuels.
• The rules created in this bill automatically end on September 30, 2027.
• Information shared by fuel suppliers during the study must be kept confidential unless they agree to share their names.

Purpose

Requires the Director of the Department of Environmental Quality (ADEQ) to
evaluate using the most recent air emissions modeling approved by the U.S.
Environmental Protection Agency (EPA), outlined gasoline blends and appropriates
$100,000 from the state General Fund (state GF) in FY 2027 to ADEQ for the
evaluation. Requires the Associate Director of the Weights and Measures
Services Division (Associate Director) of the Arizona Department of Agriculture
(AZDA) to conduct the outlined fuel blend feasibility study and appropriates
$100,000 from the state GF in FY 2027 to AZDA for the study.

Background

Fuel sold in Arizona must meet minimum standards prescribed by statute
and by Arizona Department of Agriculture Weights and Measures Division
(Division) rule. All gasoline produced and shipped to or within Arizona and all
gasoline sold or offered for sale for use in motor vehicles in a county with a
population of 1,200,000 or more persons and any portion of a county contained
in Area A (Area A) or the portion of Pinal County that is west of range 11
east, excluding the portion within Area A (Area C), must comply with one of two
outlined fuel reformulation options, subject to a waiver by the EPA to comply
with the federal Clean Air Act. All gasoline in Area A or Area C must also meet
the statutory maximum vapor pressure requirements, which vary based on the time
of year (A.R.S. ��
3-3433
and
3-3493
).

The reformulated gasoline program was mandated by the U.S. Congress in
the 1990 Clean Air Act Amendments. The Clean Air Act intended that reformulated
gasoline would be blended to burn more cleanly than conventional gasoline and
would reduce emissions of smog-forming and toxic pollutants. Reformulated
Gasoline is required in cities with high smog levels and is optional elsewhere.
Reformulated gasoline is currently used in 17 states and the District of
Columbia. About 25 percent of gasoline sold in the United States is
reformulated (
EPA
).

H.B. 2014 appropriates $100,000 from the state GF in FY 2027 to ADEQ and $100,000
from the state GF in FY 2027 to the AZDA.
