HB 2355 makes a series of technical amendments to Arizona’s groundwater code focused on reporting, metering, and recordkeeping. The bill updates definitions in the groundwater statutes and revises the rules for when a water measuring device is required for groundwater withdrawals, especially for small-scale users, certain type 2 non-irrigation grandfathered rights, and limited irrigation uses on ten or fewer contiguous acres. It also revises annual reporting requirements for groundwater pumping, transportation, and use, including reporting obligations in the Santa Cruz active management area and the Pinal active management area’s southside protection zones.
The bill expands and clarifies who must keep records and file annual reports, what information must be reported, and how reports may be combined in some circumstances. It also preserves exemptions for exempt wells and certain small users, while allowing the Department of Water Resources director to require additional information needed to meet management goals. In the Pinal southside protection zones, the bill continues to require detailed reporting for underground water withdrawals and stored water use, including replenishment and replacement information, and ties those reports to the existing penalty structure for late filing.
HB 2355 would amend several sections of Title 45, Arizona Revised Statutes, affecting the state’s groundwater management framework in active management areas, irrigation non-expansion areas, the Santa Cruz active management area, and Pinal’s southside protection zones. The practical effect is to refine compliance obligations for well owners, irrigators, groundwater transporters, irrigation districts, and other groundwater users by clarifying metering thresholds, reporting exemptions, and the content of annual reports. It does not appear to create a new regulatory program, but rather adjusts existing groundwater code requirements and enforcement mechanisms.
There is no recorded committee testimony or vote history in the provided materials, so the bill’s sentiment must be inferred from its text. The measure appears generally administrative and technical in nature, suggesting a neutral-to-supportive posture focused on improving groundwater accounting and compliance clarity rather than making a major policy shift. The inclusion of exemptions for small users and limited-acreage irrigation suggests an effort to balance oversight with reduced burden on smaller operators.
Because no transcripts or votes are available, no specific objections are documented. Based on the bill text, the most likely points of contention would be the expanded reporting and recordkeeping obligations for groundwater users outside exempt categories, the continued use of metering requirements in managed areas, and the director’s authority to require additional reporting information. Agricultural users, irrigation districts, and small well owners could view the changes differently depending on whether they are affected by the reporting thresholds and exemptions.
