HB 2795 modifies Arizona law to allow small modular reactor (SMR) construction and operation by preventing local governments from restricting these projects under specific conditions. It requires SMR developers to obtain federal early site permits and design certifications, then submit proof of these to the county board of supervisors before local zoning rules can be overridden. This directly affects SMR developers and Arizona counties, ensuring federal approvals supersede local zoning for eligible projects. The law does not alter federal requirements but clarifies that counties cannot block SMR sites once the federal steps are completed and documented.
HB 2955 sets seasonal fuel standards for gasoline sold in Maricopa County (Arizona's most populous county, exceeding 1.2 million residents) and other areas designated as "Area A." From March 31 to October 31, gasoline must meet ASTM D4814 standards with specific vapor pressure limits. From November 1 to March 31, gasoline must comply with California's Phase 2 reformulated gasoline standards and the same vapor pressure limits. The bill also establishes a 7-day review process for fuel suppliers to request temporary exemptions during ethanol or gasoline supply shortages, requiring proof of imminent shortages and state agency approval.
HB 2014 requires Arizona’s Department of Environmental Quality to model five specific gasoline blends against EPA-approved air emissions standards for areas A and C. The department must publish a report identifying blends eligible for sale in regulated areas, with findings due within 90 days of completing modeling. Arizona’s Department of Agriculture must then conduct a feasibility study on authorizing new blends not currently approved, assessing supply impact and availability, with a report due 90 days after study completion. The bill appropriates $100,000 each to both departments for these studies and expires September 30, 2027. This bill directly affects fuel suppliers, regulators, and the state’s transportation fuel supply planning.
HB 2781 establishes rules for decommissioning solar energy power plants in Arizona, directly affecting solar plant owners and operators. It requires them to submit detailed decommissioning plans, maintain financial assurance (like bonds) covering cleanup costs, and restore sites to original conditions within 18 months after shutdown. Key provisions include a 90-day cure period for permit violations, mandatory site restoration using native vegetation, and specific removal requirements for above-ground components and foundations. Local governments (cities, towns, counties) enforce these standards and can enter sites to complete decommissioning if owners fail to act. The law ensures solar projects don’t leave environmental or financial burdens on communities after they’re no longer operational.
HB 2889 appropriates $1 million from Arizona's general fund for fiscal year 2026-2027 to the state mine inspector to monitor uranium contamination. It requires the mine inspector to fund soil, water, and home testing for potential contamination and establish a statewide registry and monitoring program, partnering with tribal epidemiology centers. The bill mandates a report of findings and recommendations to state leaders by December 31, 2026. This funding is exempt from standard appropriation lapsing rules. The bill directly affects Arizona residents potentially exposed to uranium contamination, particularly in areas near mining sites.
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.
HB 2389 streamlines environmental review for utility infrastructure replacements by creating exceptions to the standard certificate of environmental compatibility requirement. It allows utilities to replace transmission line conductors/wires or adjacent power plants without new approvals, provided they meet specific conditions: 30-day notice, a public comment session, maintaining total power capacity, and replacing within sites that previously had environmental approvals (or existed before 1971). This directly affects electric utilities planning infrastructure upgrades and the Arizona Corporation Commission overseeing these reviews. The bill modifies existing rules to reduce administrative burden for routine replacements while maintaining environmental safeguards through public engagement and capacity requirements.
HB 2197 prohibits camping within one-quarter mile of natural or man-made water sources if the camping blocks wildlife or livestock from accessing water. It directly affects people camping near water holes or watering facilities in Arizona. The key provision creates a specific buffer zone (1/4 mile) around water access points to prevent denial of water to animals. This amendment updates Arizona law to clarify restrictions on camping near critical water sources. The bill is currently in early legislative stages with no votes taken yet.
HCR 2038 is a non-binding legislative resolution supporting Arizona's position in ongoing negotiations for a seven-state agreement governing the Colorado River. It states Arizona's support for a mutual agreement that protects the state's vital industries (agriculture, technology, and military) reliant on Colorado River water, while acknowledging Arizona's significant water conservation efforts (including $211 million invested to save up to 6.6 million acre-feet). The resolution emphasizes Arizona's historical water use reductions (8.9 million acre-feet) and economic contributions (75% of basin jobs and crop sales in the Lower Basin) as context for negotiations. It does not create new policy but formally endorses collaborative solutions to address the river's structural deficit and uphold the 1922 Compact.
HB 2912 requires Arizona electric utilities to submit detailed integrated resource plans to the Corporation Commission every three years. These plans must project 15-year energy demand (with low/medium/high scenarios), detail existing and planned generation assets, analyze costs and reliability of potential new plants, and use a ratepayer impact test to select the lowest-cost, most reliable option - without prioritizing emissions goals. The Commission must also obtain an independent third-party review of each plan to verify data and evaluate alternatives. The bill includes optional analysis of carbon emissions across all plant lifecycle stages (scopes 1-3), but the core requirement focuses on cost, reliability, and transparency for ratepayer decisions.
