Current through Register Vol. 50, No. 9, September 20, 2024

Section V-2315 - Closure and Post-Closure Care

A. 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 LAC 33:V.109.Hazardous Waste.6 applies.

B. 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 Subsection A of this Section, the owner or operator finds that not all contaminated subsoils can be practicably removed or decontaminated, he must either:

1. close the facility and perform post-closure care in accordance with the closure and post-closure care requirements that apply to landfills as specified in LAC 33:V.2521; or

2. perform a risk assessment to demonstrate that closure with the remaining contaminant levels is protective of human health and the environment in accordance with LAC 33:I.Chapter 13. Any such risk assessment is subject to approval by the administrative authority and must demonstrate that post-closure care is not necessary to adequately protect human health and the environment.

C. The owner or operator of a waste pile that does not comply with the liner requirements of LAC 33:V.2303.A.1 and is not exempt under LAC 33:V.2301.C and 2303.B must:

1. include in the closure plan for the pile under LAC 33:V.3511 a plan for complying with LAC 33:V.2315.A and a contingent plan for complying with LAC 33:V.2315.B in case all contaminated subsoils cannot be practicably removed at closure; and

2. prepare a contingent post-closure plan under LAC 33:V.3523 for complying with LAC 33:V.2315.B in case all contaminated subsoils cannot be practicably removed at closure.

D. The cost estimates calculated under LAC 33:V.3705 and 3709 for closure and post-closure care of a pile subject to this Section 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 LAC 33:V.2315.A.
