A miscellaneous unit that is a disposal unit must be maintained in a manner that complies with section 11-264-601 during the post-closure care period. In addition, if a treatment or storage unit has contaminated soils or ground water that cannot be completely removed or decontaminated during closure, then that unit must also meet the requirements of section 11-264-601 during post-closure care. The post-closure plan under section 11-264-118 must specify the procedures that will be used to satisfy this requirement.
