HB 2918 changes how renewable energy and storage equipment is valued for property tax purposes in Arizona through 2040. It sets different valuation rules: non-utility-owned equipment is taxed at 100% of its depreciated cost, while utility-owned equipment is taxed at 20% of depreciated cost before January 1, 2027, and 100% after that date. The bill caps depreciation at 90% of the equipment's original cost and explicitly includes all energy storage (both co-located with solar/wind and standalone). This directly affects owners of renewable energy projects, including utilities and private developers, by altering their property tax burden based on ownership type and installation timeline.
HB 2278 updates Arizona's requirements for mining companies to provide financial assurance to cover future land reclamation costs after operations end. It specifies that mining operators must use approved mechanisms like surety bonds, trust funds, or cash deposits held in third-party escrow accounts. The bill clarifies that mining companies retain all interest earned on cash deposits in escrow accounts (minus fees), and allows partial release of funds as reclamation work progresses. It also standardizes procedures for inspectors to release financial assurance once reclamation is completed, retaining 10% for monitoring and potential reseeding over a three-year period.
HB 2029 creates a Water Conservation Grant Fund to support water-saving projects in Arizona. It allows eligible entities (like local governments or nonprofits partnering with them) to apply for grants for conservation programs (up to $3 million) or projects (up to $250,000), requiring a 25% match from other sources. Applicants must disclose projected water savings, the source of saved water (groundwater or surface water), and their plan for using the saved water. The Water Infrastructure Finance Authority must adopt implementing rules within 90 days of the bill's effective date.
HB 2117 redirects $17 of the $25 annual fee for Arizona's environmental special license plates into a dedicated fund. The state natural resource conservation board will distribute $5,000 to $10,000 annually to each natural resource conservation district with an established education center. These funds must support environmental education programs that are scientifically based and address economic and social implications. The bill specifies that funds are exclusively for conservation education programs at local districts, without changing the plate fee structure.
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.
