(A) In addition to the requirements imposed by this article, the regulations promulgated by the department must require, at a minimum, that municipal solid waste incinerator ash which is disposed of at a solid waste landfill be disposed of only in the following manner:
(1) the unit is located, designed, and operated so as to protect human health and safety and the environment;
(2) the unit has a groundwater monitoring system and a leachate collection and removal system; and
(3) the unit has a single composite liner or double geomembrane liner designed, operated, and constructed of materials to restrict the migration of any constituent into and through such liner during such period as the unit remains in operation.
(B) The department shall prescribe criteria and testing procedures for identifying the properties of municipal solid waste incinerator ash that may result in entry into groundwater or surface water in such manner as may pose a hazard to human health and safety or to the environment. The department shall prescribe such criteria and testing procedures not later than eighteen months after this article is effective. Based on the criteria and testing procedures, the regulations shall permit municipal incinerator ash which does not exhibit any of the properties identified in such criteria to be disposed of in solid waste landfill units or cells meeting the applicable regulatory requirements of this section. If such ash exhibits any of the properties identified in the criteria, the department may require that it be disposed of in a landfill meeting the requirements for hazardous waste disposal.
