i. Closure Performance Standards for Central Accumulation Areas that are Container Storage, Tank Systems, or Containment Buildings

(a). At closure, the large quantity generator shall close the central accumulation area or facility in a manner that:

(i). minimizes the need for further maintenance by controlling, minimizing, or eliminating, to the extent necessary to protect human health and the environment, the post-closure escape of hazardous waste, hazardous constituents, leachate, contaminated run-off, or hazardous waste decomposition products to the ground or surface waters or to the atmosphere; and

(ii). removes or decontaminates all contaminated equipment, structures and soil and any remaining hazardous waste residues from the central accumulation area including containment system components (e.g., pads, liners, etc.), contaminated soils and subsoils, bases, and structures and equipment contaminated with waste, unless LAC 33:V.109.Hazardous Waste.5 applies.

(b). Any hazardous waste generated in the process of closing either the large quantity generator's facility or unit(s) accumulating hazardous waste shall be managed in accordance with all applicable standards of LAC 33:V.Subpart 1, including removing any hazardous wastes contained in these units within 90 days of generating it and managing these wastes in a RCRA subtitle C hazardous waste permitted treatment, storage, and disposal facility, or interim status facility.

(c). If the large quantity generator demonstrates that either any contaminated soils and wastes cannot be practicably removed or decontaminated as required in Division B.8.c.i.(a).(ii) of this Paragraph, or that the remaining contaminant levels are not protective of human health and the environment as demonstrated by the confirmatory sampling and analytical results specified in Subdivision B.8.b.ii.(c).(ii).[d] of this Paragraph, or through the use of RECAP and remedial activities under Subparagraph B.8.f of this Paragraph or LAC 33:V.2809.B.2, then the central accumulation area is considered to be a landfill. The large quantity generator shall then close the central accumulation area and perform post-closure care in accordance with the closure and post-closure care requirements that apply to landfills (LAC 33:V.4501.B and D). In addition, for the purposes of closure, post-closure, and financial responsibility, such a central accumulation area is then considered to be a landfill, and the large quantity generator shall meet all of the requirements for landfills specified in LAC 33:V.Chapter 43.Subchapters F and G.

ii. Closure Performance Standards for Central Accumulation Areas that are Drip Pads. At closure, the large quantity generator shall comply with the closure requirements of Subparagraph B.8.b, Division B.8.c.i.(a).(i), and Subclause B.8.c.i.(b) of this Paragraph, and LAC 33:V.2809.A and B.

d. Special Provisions for Closing a Central Accumulation Area Consisting of Container Storage. This Subparagraph is applicable to closure for a central accumulation area consisting of container storage. The container storage may have temporary or long-term (i.e., fixed, immovable) secondary containment.

i. Presumptive Demonstration of Closure. A large quantity generator shall be considered to have performed due diligence in closing container storage (i.e., no additional closure efforts or verification shall be required) and met the closure performance standards of Clause B.8.c.i of this Paragraph provided the following conditions are met.

(a). All information has been placed in the operating record as required by Clause B.8.a.ii of this Paragraph.

(b). All containers were removed from the central accumulation area and were either sent off-site for treatment or disposal or were transferred elsewhere on-site for treatment, storage, or disposal authorized by LAC 33:V.Subpart 1.

(c). Weekly inspection logs, summary, or other information (e.g., photographs, written documentation of spill clean ups, etc.) in the operating record demonstrate during the entirety of the accumulation period that:

(i). there were no spills, leaks, or releases of hazardous waste or hazardous constituents onto the secondary containment or soil immediately surrounding and beneath the unit, or they were properly cleaned up and managed in order to meet the closure performance standards; and

(ii). for container storage with long-term (i.e., fixed, immovable) secondary containment, there were no visible signs of significant cracks, gaps, or deterioration of the secondary containment, or they were properly repaired in a timely manner. (Any sumps or engineered swales serving as a receptacle for drainage in the secondary containment should be clearly mentioned.)

(d). For container storage with long-term (i.e., fixed, immovable) secondary containment, after removal of all waste a final inspection log/report and other information (i.e., photographs, etc.) in the operating record demonstrate that:

(i). there was no significant staining or other signs of contamination from hazardous waste on the secondary containment, including sumps or engineered swales serving as a receptacle for drainage in the secondary containment; and

(ii) . there were no visible signs of significant cracks, gaps or deterioration for sumps or engineered swales serving as a receptacle for drainage;

(e). additional demonstration efforts of closure as specified in Clause B.8.d.ii of this Paragraph below are not necessary; and

(f). a signed statement from the responsible official is submitted with the subsequent notification as required by Division B.8.b.ii.(b).(i) of this Paragraph stating the closure performance standards have been met through the presumptive demonstration of closure requirements of this Clause.

ii. Additional Demonstration Efforts of Closure for Container Storage

(a). It is the responsibility of the large quantity generator to be aware of the closure performance standards and to make a good faith effort to demonstrate that the closure performance standards have been met. Additional decontamination procedures and confirmatory sampling of the final rinsate and/or soil (and groundwater, if deemed necessary) shall be required if either:

(i). any of the conditions of Clause B.8.d.i of this Paragraph are not met; or

(ii). the potential future use of the area requires additional efforts to demonstrate that sufficient decontamination has been achieved (e.g., if a secondary containment area has a potential future use for storing food grade products, then decontamination procedures and confirmatory sampling of the final rinsate may be required to verify that it has been adequately decontaminated);

(b). Container storage requiring additional closure efforts shall meet the notification requirements of Subclause B.8.b.i.(k) of this Paragraph (i.e., prior notification) and Subclause B.8.b.ii.(c) of this Paragraph (i.e., closure report for subsequent notification), unless a sufficiency demonstration is approved by the Office of Environmental Services in accordance with Subparagraph B.8.e of this Paragraph. The Office of Environmental Services shall review and approve the closure report and notification to ensure that the closure performance standards have been met.

e. Sufficiency Demonstration of Closure

i. Prior to, or during closure, the large quantity generator may petition the Office of Environmental Services to meet the closure performance standards through alternate, reduced, or eliminated requirements for closure notifications in Subparagraphs B.8.a and b of this Paragraph. These requirements may include, but are not limited to, documentation, submittal information, decontamination procedures, confirmatory sampling and analysis on the rinsate, and confirmatory sampling and analysis on the soil (and groundwater, if deemed necessary) immediately surrounding and beneath the unit.

ii. A sufficiency demonstration shall not alleviate the large quantity generator's requirement to meet the closure performance standards in Subparagraph B.8.C of this Paragraph, but rather the demonstration of how the closure performance standards have been met.

iii. A sufficiency demonstration will only be approved by the Office of Environmental Services if merited by the supporting information and site-specific conditions.

(a). The following is a partial list of factors the Office of Environmental Services may consider in approving the sufficiency demonstration: accumulation time period; quantity and nature of the hazardous waste; containment design and condition; proper operations and maintenance; any additional protections (e.g., leak detection, etc.); soil and groundwater classification; overall compliance history; existing or future corrective action measures include the central accumulation area and/or the facility (e.g., site-wide corrective action being implemented through an enforceable agreement with the large quantity generator, or an order of the department specifically includes the central accumulation area and/or the facility); and any other relevant information requested by the Office of Environmental Services.

(b). A few example scenarios for a sufficiency demonstration include, but are not limited to: decontamination might not be necessary for a tank system that accumulated diluted wastewater; confirmatory rinsate sampling might not be necessary for a tank system that will receive a hazardous waste permit to manage the same waste; and confirmatory soil (and groundwater, if deemed necessary) sampling might not be required for a tank system that was used for a one-time event.

iv. The Office of Environmental Services' approval of a sufficiency demonstration may require additional or alternate closure efforts or verification from the large quantity generator depending on site-specific conditions.

v. Upon approval by the Office of Environmental Services, the petitioner shall incorporate the relevant information of the sufficiency demonstration into the closure notification requirements of Subparagraphs B.8.a and b of this Paragraph, as applicable. The large quantity generator shall maintain all documentation in support of the sufficiency demonstration.

f. The use of Risk Evaluation/Corrective Action Program (RECAP) and remedial activities for the closure of container storage, tank systems, and containment buildings.

i. If there is suspected or confirmed contamination in the environmental media (i.e., soil or groundwater) immediately surrounding and beneath the unit as demonstrated by the confirmatory sampling and analytical results specified in Subdivision B.8.b.ii.(c).(ii).[d] of this Paragraph or by other evidence, risk evaluation and/or remedial activities may be conducted by the large quantity generator in order to demonstrate that the closure performance standards have been met.

ii. The risk evaluation and/or remedial activities may be conducted, either in addition to, or instead of, the confirmatory sampling and analysis required by Subdivision B.8.b.ii.(c).(ii).[d] of this Paragraph.

iii. The risk evaluation and/or remedial activities shall be:

(a). in accordance with RECAP as referenced in LAC 33:1.Chapter 13 (Risk Evaluation/Corrective Action Program);

(b). under the direction of the Office of Environmental Assessment; and

(c). subject to all cost recovery provisions of the department.

iv. A site investigation work plan shall be submitted to the Office of Environmental Assessment in accordance with Appendix B of RECAP.
