groundwater management; technical correction

HCR 2043 is a technical correction to Arizona’s groundwater management law, specifically amending Section 45-576.05. It clarifies how groundwater replenishment districts calculate whether a member’s water use aligns with regional management goals when certain conditions (like surface water availability) are no longer met. Key changes include: (1) requiring districts to count surface water, treated wastewater, and external groundwater withdrawals instead of local groundwater; (2) capping local groundwater use at 100 times the highest historical withdrawal in the active management area; and (3) requiring municipal providers with "assured water supply" designations to seek redesignation if conditions change. The bill applies directly to groundwater districts and their municipal members in Arizona, and requires voter approval to take effect.
