SB 1335 requires Arizona's water banking commission to submit an annual report by July 1st each year, detailing all transactions and activities related to the state's water banking fund. The report must include specific financial accounting (monies expended and remaining), water storage volumes, long-term credit distributions, and a 10-year plan for future water banking services - including protecting against Colorado River shortages and supporting tribal water rights settlements. The commission must also post this report on its public website. This bill focuses solely on transparency and reporting requirements for the existing water banking program.

HB 4157: commerce; 2026-2027

This bill updates how money from Arizona's state lottery is distributed and clarifies rules for examining insurance companies. It ensures that funds are first used to pay off lottery-related bond debts, then allocates specific amounts to various programs including wildlife conservation, child safety, health education, and homeless shelters. The legislation also establishes a minimum deposit requirement for the state general fund before certain heritage funds can receive money and sets a schedule for quarterly transfers. Additionally, it mandates that the insurance director examine domestic insurers at least once every five years and allows for accepting reports from other states to avoid duplicate reviews.

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.

HB 4144: 2026-2027; environment.

This bill outlines how specific environmental funds in Arizona can be used during the 2026-2027 fiscal year. It allows money from the underground storage tank fund to cover administrative costs and address sewage discharge problems in border areas like Naco. The legislation also permits the use of water banking and water protection funds to pay legal fees and cover departmental administrative expenses. Additionally, it sets a $15 million spending cap for the water quality assurance revolving fund and keeps vehicle emissions testing fees at their 2025 levels. Although the bill passed the legislature, it was vetoed by the Governor.

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 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.

HCM 2008: gas tax elimination

HCM 2008 is a memorial from Arizona's state legislature requesting the federal government eliminate the gas tax on Arizona's "Cleaner Burning Gas" blend during specific summer months. It targets the federal excise tax applied to this specialized fuel, which is more expensive to produce than standard gasoline but required to meet air quality standards in Maricopa and Pinal counties. The memorial asks Congress to either temporarily exempt this fuel from tax (May 1-Sept. 30) or grant the EPA emergency authority to waive the tax for EPA-approved blends meeting air quality standards. This request directly affects Arizona residents in those counties who use this fuel, aiming to lower local gas prices by removing the tax burden on the specialized blend.

HB 2053: appropriation; stormwater recharge mapping; sites

HB 2053 appropriates $100,000 from the state general fund to Arizona's Department of Water Resources for updated stormwater recharge mapping in fiscal year 2026-2027. Within 180 days, the department must collaborate with agricultural districts and the state natural resource conservation board to create a map identifying potential stormwater recharge sites. The map must show locations on public or private lands with suitable soil for groundwater recharge, excluding areas with existing surface water rights or where runoff would enter streams. This bill defines "stormwater" as rainwater runoff that doesn't enter streams and would otherwise evaporate.
