At closure, the owner or operator must
remove or decontaminate all waste residues, contaminated containment system
components (liners, etc.), contaminated subsoils, and structures and equipment
contaminated with waste and leachate, and manage them as hazardous waste unless
paragraph (D) of rule
of the Administrative Code applies.
If, after removing or decontaminating all
residues and making all reasonable efforts to effect removal or decontamination
of contaminated components, subsoils, structures, and equipment as required in
paragraph (A) of this rule, the owner or operator finds that not all
contaminated subsoils can be practicably removed or decontaminated, he must
close the facility and perform post-closure care in accordance with rule
of the Administrative Code.
The owner or operator of a waste pile
that does not comply with the liner requirements of paragraph (A)(1) of rule
of the Administrative Code and is not exempt from them in accordance with
paragraph (C) of rule
of the Administrative Code or paragraph (B) of rule
of the Administrative Code must:
in the closure plan for the pile in accordance with rule
of the Administrative Code both a plan for complying with paragraph (A) of this
rule and a contingent plan for complying with paragraph (B) of this rule in
case not all contaminated subsoils can be practicably removed at closure; and
Prepare a contingent
post-closure plan in accordance with rule
of the Administrative Code for complying with paragraph (B) of this rule in
case not all contaminated subsoils can be practicably removed at closure.
The cost estimates
calculated in accordance with rules
of the Administrative Code for closure and post-closure care of a pile subject
to this paragraph must include the cost of complying with the contingent
closure plan and the contingent post-closure plan, but are not required to
include the cost of expected closure under paragraph (A) of this rule.
