A

(4) A summary of explosive gas migration and
generation by the sanitary landfill
facility.
(5) An assessment of the integrity and
stability of the cap system if post-closure care activities cease.
[Comment: If the landfill shows an
improvement to leachate quality, the quantity of leachate generated will not
cause an outbreak or slope failure, that ground water monitoring is no longer
needed, that it is not generating explosive gas which has the potential to
migrate underground, and that the cap system will maintain its integrity and
stability if post-closure care activities cease, the director may release the
owner, operator, or permittee from continuing post-closure care
activities.]
