grandfathered right; Willcox AMA; extension

HB 2551 requires individuals with existing groundwater rights ("grandfathered rights") in Arizona's Willcox Active Management Area to apply for a certificate of right with the Department of Water Resources within 21 months of the area's designation. It directly affects current groundwater users in this region who rely on pre-existing rights. The bill sets a deadline for these applications and specifies that the requirement expires on December 31, 2026. The bill was passed by the legislature in April 2025 but was vetoed by the Governor on April 18, 2025, so it did not become law.
