Relating to the regulation of groundwater produced in the boundaries of a groundwater conservation district.

HB 304 limits groundwater transfers outside conservation districts by capping total permits for any single applicant (including subsidiaries) at 5% of the district's modeled available groundwater by December 2025. It requires groundwater conservation districts to seek approval from at least two-thirds of other districts in the management area before issuing permits for large transfers (25,000+ gallons/day), considering impacts on regional water goals. Exceptions are made for potable water transfers within a utility's service area or emergency interconnects between utilities. The bill directly affects districts, large water users, and utilities seeking to move groundwater outside district boundaries. It applies only to permits issued after the law's effective date.
