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.
v. The risk evaluation must demonstrate that
the closure is protective of human health and the environment and that
post-closure care is not necessary in order for Subclause B.8.c.i.(c) of this
Paragraph (i.e., closure as a landfill) not to apply.
g. Contamination from Other Sources. The
Office of Environmental Services may conditionally approve the closure of a
central accumulation area whereby the large quantity generator agrees to
address contamination remaining in the environmental media (i.e., soil or
groundwater) through additional remedial activities under the direction of the
Office of Environmental Assessment. The large quantity generator must
successfully demonstrate that either:
i. the
contamination is from a source other than hazardous waste managed in the unit;
or
ii. the contamination caused by
the hazardous waste managed in the unit is comingled with contamination caused
by another source.
h.
Notification of Newly-Identified Release. Any newly identified release of
hazardous waste to the environment must be reported either to the Louisiana
State Police, Department of Public Safely in accordance with LAC 33:V.105.J.l
(Emergency Conditions) or SPOC in accordance with LAC 33:V.105.J.2
(Nonemergency Conditions).
i.
Closure Inspections. The department may inspect the central accumulation area
before, during, or after the closure activities have been completed.
j. Closure Guidance. The large quantity
generator should review all guidance that may be issued by the department and
posted on its website including, but not limited to, guidance on confirmatory
sampling for aboveground structures and environmental media. The purpose of
such guidance is to ensure best management practices, promote consistency, and
produce technically defensible closures. Any such guidance issued by the
department is not regulation and shall not substitute for the requirements of
Subparagraph B.8 of this Paragraph. Thus, any guidance does not impose any new
requirements. The department shall retain discretion to use approaches on a
case-by-case basis that differ from such guidance where appropriate. The
department will base decisions regarding closure activities required by
Subparagraph B.8 of this Paragraph in accordance with the Act and regulations
as applied to the specific facts of the closure. Whether or not the
recommendations in any guidance are appropriate in a given situation will
depend on site-specific circumstances.
k. Notification Requirements for Closures
Initiated Prior to July 20, 2020.
i. For
purposes of this Subparagraph, initiation of closure shall consist of removing
the final volume of hazardous waste from the central accumulation area(s) with
the intent of no longer using the unit(s) for accumulation of hazardous
waste.
ii. A large quantity
generator shall meet the closure performance standards of Subparagraph B.8.C of
this Paragraph regardless of when closure was initiated.
iii. A large quantity generator that
initiated closure prior to July 20, 2020 shall either:
(a), comply with the notification
requirements of Subparagraphs B.8.a and b of this Paragraph; or
(b). perform the following:
(i). complete all closure activities and meet
the closure performance standards within 180 days of July 20, 2020, unless such
deadline is extended in writing by the Office of Environmental Services upon
proper showing by the large quantity generator that such extension is
warranted; and
(ii). submit a
Certification of No Hazardous Waste Activity form, available on the
department's website, to the Office of Environmental Services no later than 30
days after completion of all closure activities. (The department may conduct an
inspection of the central accumulation area(s) in order to verify that the
closure performance standards were met.)
9. Land Disposal
Restrictions. The large quantity generator complies with all applicable
requirements under LAC 33:V.Chapter 22.
