SB 1445: water quality; testing; on-site

SB 1445 modifies Arizona's water quality regulations to allow small municipalities (with populations between 1,000 and 10,000) to use EPA-approved on-site equipment for bacteriological testing of wastewater. It updates permit requirements for facilities discharging pollutants, including specifying that small towns may conduct this testing on-site instead of sending samples to external labs. The bill directly affects local governments and wastewater facilities in smaller communities by streamlining testing procedures while maintaining EPA standards. It also clarifies permit processes for aquifer protection and aligns with federal Clean Water Act requirements.

HB 2013: exceptional events; air quality; wildfires

HB 2013 amends Arizona's air quality statute to clarify how the state handles "exceptional events" like wildfires. It requires the state air quality agency to develop policy statements for such events, considering Arizona's unique conditions, and mandates submitting wildfire-related demonstrations to the U.S. EPA if federally managed wildfires affect the state. The bill also adds a requirement for the agency to issue daily PM-10 dust forecasts for nonattainment areas, identifying risk levels based on weather, pollution data, and historical patterns. These changes directly affect the state air quality agency's procedures for managing air pollution during extreme events.

HB 2494: certificate; environmental compatibility; zoning; exemption

HB 2494 creates special zoning districts for aggregate mining operations in Arizona counties. It requires county boards to establish these districts based on petitions from residents near existing operations and form committees with equal representation from mining operators and community members to set local rules. The bill exempts aggregate mining from standard zoning restrictions within designated districts while requiring operators to follow specific environmental and operational standards for dust, noise, and site reclamation. This directly affects counties establishing zoning districts and aggregate mining operators seeking to expand or operate within these areas.

HCR 2020: for-sale housing; development; groundwater replenishment

HCR 2020 is a non-binding legislative resolution expressing support for for-sale housing developments outside designated water service areas, provided they enroll in the Central Arizona Groundwater Replenishment District (CAGRD) and replenish groundwater as required by Arizona's water rules. It directly affects new housing projects in Phoenix, Pinal, and Tucson active management areas by requiring groundwater replenishment to offset usage. The resolution highlights that CAGRD has enabled over 400,000 homes to be built without impacting groundwater tables since 1995, aligning with existing state water management requirements.

HB 2918: renewable energy equipment; valuation; depreciation

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 2117: natural resource conservation board; fund

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: small modular reactors; zoning; approval

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: gasoline formulations; air quality

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: fuel formulations; modeling; study; appropriation

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.

HB 2145: petition; waiver; fuel formulations

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.
