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).
