An owner or operator of a solid waste disposal facility licensed under section 1310-N shall provide the department assurance of its financial ability to satisfy the estimated cost of corrective action for known releases from the facility and its financial capacity to satisfy the estimated cost of closure and postclosure care and maintenance at the facility for a period of at least 30 years after closure. The board may adopt rules that increase or decrease that postclosure care period, as long as those rules are consistent with applicable federal rules. The department may consider the use of more than one acceptable form of financial assurance per facility to satisfy the financial assurance requirement of this section. This section applies to all privately owned solid waste disposal facilities licensed by the department, including facilities licensed by the department before June 16, 1993. This section does not apply to a municipally owned or operated solid waste disposal facility that accepts exclusively special waste, construction and demolition debris, land-clearing debris or any combination of those types of waste or to a municipally owned or operated solid waste disposal facility licensed before June 16, 1993.
