HB 2452 requires counties in Arizona with over 125,000 residents to include specific land use designations for data centers and small modular reactors in their comprehensive plans. The bill mandates counties to identify sufficient land locations and extents for data center construction and operation, and for larger counties (over 200,000 residents) to designate land for small modular reactors. It also adds provisions for energy planning, including incentives for renewable energy use and policies to support efficient energy consumption. This bill directly affects county planning processes by requiring new land-use considerations for data centers and nuclear energy infrastructure within existing planning frameworks.
HB 2493 amends Arizona's zoning laws to specifically protect land use for small modular reactor (SMR) manufacturing facilities, preventing local governments from restricting such facilities on five or more contiguous commercial acres. The bill's primary focus, however, is establishing new zoning districts for aggregate mining operations, requiring counties to create designated zones for mining activities with specific standards for dust control, noise, and land reclamation. It also creates recommendation committees composed of mining operators and local residents to advise county boards on mining zoning regulations. The bill directly affects counties, mining operators, and SMR manufacturers by limiting local regulatory authority over these specific land uses. (Note: The bill's title mentions SMRs, but the core provisions primarily address aggregate mining zoning.)
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 2331 requires Arizona's public power entities and public service corporations to consider specific energy criteria when making planning and procurement decisions. The bill defines "clean energy" to include natural gas and nuclear power (if emissions meet pipeline-quality standards), "reliable energy" (requiring consistent power output and grid stability), and "affordable resource energy" (prioritizing stable costs and long-term savings). It mandates that these entities prioritize domestic fuel sources and minimize reliance on foreign materials for critical energy needs. The law directly affects how Arizona's energy providers evaluate and select power sources, emphasizing domestic availability, cost stability, and grid reliability.
HB 2456 removes zoning restrictions for small modular nuclear reactors (SMRs) in Arizona when they are colocated with a large industrial energy user that already has all required zoning approvals. It requires SMR developers to provide public notice and hold at least one public comment session in the affected county before construction. This bill directly affects SMR developers seeking to build facilities adjacent to existing industrial energy sites. The law does not create new regulations for SMRs but eliminates local zoning barriers under these specific conditions.
HB 2798 appropriates funds to the University of Arizona’s Arizona Geological Survey to study minerals and metals needed for advanced nuclear reactors (including generation III+ and IV small modular reactors). The study requires mapping all known mineral reserves across Arizona, detailing quantities and grades for each site. The Geological Survey must submit a final report to state officials and publish it online by a specified deadline. This bill directly affects Arizona’s geological data collection efforts and state officials receiving the findings, with no direct impact on the public or businesses.
SB 1418 amends Arizona zoning law to allow small modular reactors (SMRs) to be constructed and operated without local zoning restrictions in counties with fewer than 500,000 residents, provided they are located at a site where a large industrial energy user has already secured all necessary zoning approvals. This prevents counties from imposing additional zoning rules on such SMR projects, specifically targeting smaller counties (e.g., excluding Maricopa County, which exceeds 500,000 residents). The bill defines key terms like "colocated" and "large industrial energy user" based on rules set by the Corporation Commission. It directly affects developers of SMRs and local governments in smaller counties, aiming to streamline clean energy infrastructure development by removing regulatory barriers.
