Sec. 4.
(a) Owners
				or operators of restricted waste sites Type I and Type II and nonmunicipal
				solid waste landfills shall have a written closure plan. The closure plan must
				be submitted with the permit application in accordance with
				329
				IAC 10-11 and be approved by the commissioner as part
				of the permit. The approved closure plan will become a condition of the
				permit.
(b) The closure plan must
				identify the steps necessary to completely close the restricted waste site Type
				I or Type II or nonmunicipal solid waste landfill at any point during its
				intended life in accordance with section 1 of this rule. The plan must be
				certified by a registered professional engineer. The closure plan must include
				the following:
(1) A description of the steps
				that will be used to partially close, if applicable, and finally close the
				facility in accordance with section 1 of this rule.
(2) A listing of labor, materials, and
				testing necessary to close the facility.
(3) An estimate of the expected year of
				closure and a schedule for final closure. The schedule must include:
(A) the total time required to close the
				facility; and
(B) the time required
				for completion of intervening closure activities.
(4) An estimate of the cost per acre of
				providing final cover and vegetation. Such cost must be that which is necessary
				for providing the following, but must not be less than five thousand dollars
				($5,000) per acre:
(A) Two (2) feet of
				compacted clay soil.
(B) Six (6)
				inches of topsoil.
(C)
				Vegetation.
(D) Certification of
				closure, including any testing necessary for such certification.
(5) The closure plan must
				separately identify any closure costs for items other than providing final
				cover and vegetation.
(6) The
				closure plan must list a closure cost estimate equal to the costs specified by
				subdivision (5) plus the product of the total area of the site permitted for
				filling and the cost per unit area specified by subdivision (4). Closure costs
				must be calculated based on the cost necessary for the work to be performed by
				a third party.
(7) The estimate of
				the cost per acre of providing final cover and vegetation must be that
				necessary for providing the activities as specified in the closure plan;
				however, the sum of the closure cost estimate and post-closure cost estimate
				must not be less than fifteen thousand dollars ($15,000) per acre or fraction
				of an acre covered by the permitted facility.
(8) If the restricted waste site Type I or
				Type II or nonmunicipal solid waste landfill utilizes the incremental closure
				standard, as contained in
				329 IAC
				10-39-2(b)(2)(B), then for each
				yearly period following the beginning of operation of the facility, the plan
				must specify the maximum area of the facility into which solid waste will have
				been deposited through that year of the facility's life and must delineate such
				areas on the copy of the facility's final contour map. The closure plan must
				list closure cost estimates for each year of the anticipated life of the
				facility equal to the costs specified by subdivision (5), plus the product of
				the noted maximum areas of the site and the cost per unit area specified by
				subdivision (4).
