Evaluation and permitting of projects requiring large water appropriations provided.

HF 3007 establishes a preapplication evaluation process for projects requiring large water use (over 100 million gallons per year or 250,000 gallons per day), requiring applicants to consult with the state commissioner early in development and share details about water use, location, and source. The commissioner evaluates water availability at potential sites and responds in writing, with early communications kept confidential until a formal permit application is submitted. The bill also adds requirements for water permits to promote conservation and address conflicts, and mandates environmental impact statements for data centers expanding by 100 megawatts or more.
