assured water supply; certificate; model

HB 2094 allows Arizona's Department of Water Resources to review pending applications for "certificate of assured water supply" in the Phoenix Active Management Area (submitted between 2021-2023 but not yet approved). It requires municipal water providers to calculate and assign 25% of their annual excess groundwater deliveries as long-term storage credits to the Central Arizona Groundwater Replenishment District. This assignment reduces the provider's annual replenishment tax obligation and continues as long as the land retains groundwater replenishment requirements. The bill expires December 31, 2028, and applies only to applications supported by specific historical groundwater models.
