The bill mandates that uranium waste, including tailings from the mining, milling, or processing of uranium ore in New Mexico, must be disposed of exclusively in federally managed underground facilities that are specifically designed for hazardous waste containment. This requirement aims to ensure the safe and regulated disposal of hazardous materials associated with uranium mining activities.

Additionally, the bill restricts state agencies from issuing permits for the disposal of uranium waste in any facilities that do not meet the criteria of being federally managed underground depositories. This provision reinforces the focus on utilizing federally regulated sites for the disposal of hazardous uranium waste, thereby enhancing environmental safety and compliance with federal standards.
