Primary SB 1217
Introduced · Arizona Senate · Lead sponsor
water supply development fund; cap

Maddy summarySB 1217 sets maximum limits on funding from Arizona's Water Supply Development Revolving Fund: loans to water projects cannot exceed $3 million per loan, and grants cannot exceed $2 million per grant. The bill directly affects eligible water providers and entities developing water infrastructure projects across the state by capping the financial assistance they can receive. Key provisions include establishing these specific dollar limits for loans and grants, while maintaining the fund's existing uses for debt purchases, insurance, studies, and administration. The bill modifies existing funding rules without creating new programs or altering the fund's overall purpose.

technical correction; child hearing programs

Maddy summarySB 1196 is a technical correction bill amending Arizona Revised Statutes § 36-899.03. It revises the requirement for the director to develop rules governing standards and procedures for child hearing evaluation services. The bill clarifies that the director must "adopt" rules (correcting a prior drafting error) rather than "develop" them, streamlining the regulatory process. This procedural update affects how public health officials implement hearing evaluation programs for children but does not change service requirements or eligibility.

technical correction; air pollution; orders

Maddy summarySB 1337 is a technical correction bill amending Arizona Revised Statutes § 49-439, which governs air pollution conditional orders. It updates the statute to correct a reference to the "air pollution control permit administration fund" (changing it from section 49-555 to 49-455) and clarifies the timeline for regulatory decisions on petitions (30 days after hearings, 60 days if no hearing). The bill directly affects air pollution regulators and facilities operating under conditional orders by standardizing procedural requirements for granting or denying petitions. It does not create new policy but ensures existing rules reference the correct funding section and procedural deadlines.

Primary SB 1514
Introduced · Arizona Senate · Lead sponsor
groundwater permits; technical correction

Maddy summarySB 1514 amends Arizona Revised Statutes § 45-516 to clarify that permits for non-irrigation users withdrawing poor quality groundwater must have durations based on the "estimated life of the source," rather than a fixed 35-year term. This technical correction applies to existing permits issued under this provision, affecting users who withdraw groundwater deemed unusable for other purposes. The bill does not change eligibility or new permit requirements but ensures permit terms align with the actual lifespan of the groundwater source. It is a procedural adjustment to existing law, not a policy change.

off-highway vehicles; weight

Maddy summarySB 1519 amends Arizona law to define "All-terrain vehicle" with specific weight limits for two categories. It sets a maximum unladen weight of 1,200 pounds for one type (motor vehicles designed for recreational nonhighway travel) and 2,350 pounds for another type (recreational off-highway vehicles). These definitions will directly affect how off-highway vehicles are classified and regulated under Arizona's vehicle laws. The bill formalizes these weight criteria into the legal definition without altering existing weight standards.

veterinary medical examining board; continuation

Maddy summarySB 1199 sets a specific end date for Arizona's State Veterinary Medical Examining Board, terminating its operations on July 1, 2034. The bill also repeals related laws on January 1, 2035, ensuring the board's functions end with a clear timeline. This affects veterinary professionals and practices regulated by the board, as its oversight will conclude by 2034. The legislation is procedural, establishing a defined duration for the board's existence rather than changing regulatory standards.

industrial commission; revisions

Maddy summarySB 1515 revises Arizona's Industrial Commission statutes to update the agency's authority and create a new resource officer position. The bill amends the commission's general powers to clarify its role in handling confidential information exchanges with other agencies and promoting dispute resolution between employers and employees. It also establishes a resource officer to help workers understand workers' compensation benefits and procedures without providing legal advice. Additionally, the bill clarifies key definitions (like "employer" and "commission") to ensure consistent application of workplace safety and compensation laws. These changes aim to improve the commission's efficiency and accessibility for Arizona workers and employers.

school districts; funds; financial reports

Maddy summarySB 1763 amends Arizona law (ARS § 15-341) to clarify how school districts must handle surplus funds from gifts, grants, or devises. It requires districts to either use leftover funds to reduce school district taxes for the budget year or transfer them to the Additional Monies Fund (as specified in ARS § 15-1232), unless the gift/grant terms prohibit this. This directly affects all Arizona public school districts managing these specific funds. The bill does not change existing requirements for depositing other school monies or reporting procedures.
