R315-265-110. Closure and Post-Closure -- Applicability

  Except as Section R315-265-1 provides otherwise:

  (a) Sections R315-265-111 through 265-115, which concern closure, apply to the owners and operators of all hazardous waste management facilities; and

  (b) Sections R315-265-116 through R315-265-120, which concern post-closure care, apply to the owners and operators of:

  (1) All hazardous waste disposal facilities;

  (2) Waste piles and surface impoundments for which the owner or operator intends to remove the wastes at closure to the extent that these sections are made applicable to such facilities in Sections R315-265-228 or R315-265-258;

  (3) Tank systems that are required under Section R315-265-197 to meet requirements for landfills; and

  (4) Containment buildings that are required under 40 CFR 265.1102, which is adopted and incorporated by reference, to meet the requirement for landfills.

  (c) Section R315-265-121 applies to owners and operators of units that are subject to the requirements of Subsection R315-270-1(c)(7) and are regulated under an enforceable document, as defined in Subsection R315-270-1(c)(7).

  (d) The Director may replace all or part of the requirements of Sections R315-265-110 through 265-121, and the unit-specific standards in Subsection R315-265-111(c), applying to a regulated unit, as defined in Section R315-264-90, with alternative requirements for closure set out in an approved closure or post-closure plan, or in an enforceable document, as defined in Subsection R315-270-1(c)(7), where the Director determines that:

  (1) A regulated unit is situated among solid waste management units, or areas of concern, a release has occurred, and both the regulated unit and one or more solid waste management unit(s), or areas of concern, are likely to have contributed to the release, and

  (2) It is not necessary to apply the closure requirements of Sections R315-265-110 through 265-121, those referenced herein, or both, because the alternative requirements will protect human health and the environment, and will satisfy the closure performance standard of Subsections R315-265-111(a) and (b).
