Certain determinations required before conducting environmental review and issuing permits relating to proposed nonferrous sulfide ore projects.

HF 954 requires Minnesota officials to confirm that similar nonferrous sulfide ore mining operations (like copper, nickel, or gold mines) have operated safely for at least 10 years without pollution before conducting environmental reviews or issuing permits. Applicants must prove a comparable mine in the same climate and water conditions operated without hazardous releases for a decade using similar reclamation methods. The bill mandates public comment periods and potential hearings if new evidence challenges proposed approvals. Existing permits for such projects must be renewed every 10 years with updated safety reviews. It explicitly excludes iron ore mining from these requirements.
