reporting; groundwater pumping; measuring

HB 2162 is a definitional amendment to Arizona's groundwater management law, updating terms like "active management area," "grandfathered right," and "farm unit" in Section 45-402. It clarifies existing terminology used in groundwater regulation but does not create new reporting requirements, measurement systems, or policy changes. The bill directly affects groundwater users, agricultural operations, and water management districts by standardizing how key terms are applied under current law. This is a procedural update to definitions, not a substantive policy shift.
