HB 2442 proposes the creation of Temporary Non-Expansion Areas (TNAs) in Arizona to manage groundwater resources in areas not currently covered by Active Management Areas or Irrigation Non-Expansion Areas. The bill sets forth a petition process requiring signatures from at least half of the groundwater irrigation users and 10% of registered voters in the area to initiate the designation of a TNA. Once established, the TNA would restrict new irrigation with groundwater and the drilling of new wells for five years, after which the Arizona Department of Water Resources would review groundwater levels and potentially authorize new wells.

The bill was vetoed by the Governor, who expressed concerns that it does not offer sufficient solutions for rural communities to safeguard their water resources. The bill also includes procedural details for public meetings, elections for TNA designation, and a review of groundwater status, as well as technical amendments related to well drilling fees.
