(b) Extend the post-closure care period applicable to the hazardous waste management unit or facility if he the director finds that the extended period is necessary to protect human health and the environment (e.g., leachate or groundwater monitoring results indicate a potential for migration of hazardous wastes at levels which may be harmful to human health and the environment).

(2) Is necessary to reduce a threat to human health or the environment.

(D) All post-closure care activities must shall be in accordance with the provisions of the approved post-closure plan as specified in rule 3745-55-18 of the Administrative Code.
