Revises various provisions relating to environmental hazards. (BDR 46-265)

AB 40 revises Nevada's environmental regulations for mining reclamation and solid waste management. It updates definitions to require stabilization of process fluids during mining operations (Section 13), expands the Division of Environmental Protection's authority to issue compliance orders and place liens on property (Sections 10-11), and clarifies how federal plans interact with state requirements for permits (Section 18). The bill also revises solid waste management definitions to include recycling (Section 28.3), requires detailed reclamation plans for mining (Section 17), and updates landfill permit rules to prohibit hazardous waste acceptance (Section 32). These changes directly affect mining operators, waste management facilities, and state agencies administering environmental permits. The bill passed both chambers and was signed into law on June 3, 2025.
