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

SB 28 limits groundwater transfers outside a conservation district by restricting permits that would allow an applicant to exceed 5% of the district's modeled available groundwater (effective after December 2025). It requires groundwater districts to obtain approval from at least two-thirds of neighboring districts in the management area before issuing permits for transfers exceeding 25,000 gallons daily, considering regional water goals. Exceptions apply for potable water transfers to retail utilities within their service areas or emergency interconnects between utilities. The bill directly affects entities seeking large-scale groundwater permits and groundwater conservation districts managing water transfers. These provisions aim to regulate cross-district groundwater use while preserving regional water sustainability goals.
