(4) Post-closure use of property must never be allowed to disturb the integrity of the final cover, liner(s), or any other components of the containment system, or the function of the monitoring systems, unless the Division determines that the activities are necessary to meet the requirements of this Chapter.

(b) Methane from the site is not migrating above the Lower Explosive Limit at the property boundary; and

(c) The landfill is stable and will not pose a threat to human health or the environment and is currently in the closure or post-closure period.
