Certain users of large amounts of groundwater required to apply for their own water-use permit instead of modifying an existing municipal permit.

HF 3793 requires large groundwater users (those exceeding 100 million gallons annually or 50% of a municipality's current water allocation) to apply for their own water-use permits instead of modifying existing municipal permits. This affects industrial and commercial entities, including data centers, whose water use meets these thresholds. Key provisions include mandatory public comment periods for new permits, potential aquifer testing, and monthly reporting for threshold users - compared to annual reporting for smaller users. The bill aims to strengthen oversight of significant groundwater withdrawals while ensuring public input and watershed protection.
