Current through August 26, 2024
(1) To close a facility, follow your department-approved closure plan and follow notification requirements.
(a) Submit your closure plan at
the time you submit your notice of intent to operate under a standardized
license. Final issuance of the standardized license constitutes approval of the
closure plan and the plan becomes a condition of the standardized
license.
(b) The department's
approval of the plan shall ensure that the approved plan is consistent with ss.
NR 667.0111 to 667.0115, 667.0176, 667.0201, and
667.1108.
(2) Satisfy the requirements for content of closure plan. The closure plan shall identify steps necessary to perform partial and final closure of the facility. The closure plan shall include, at least:
(a) A
description of how each hazardous waste management unit at the facility subject
to this subchapter will be closed according to s.
NR 667.0111.
(b) A description of how final closure of the
facility will be conducted according to s.
NR 667.0111. The description shall identify the maximum
extent of the operations which will be unclosed during the active life of the
facility.
(c) An estimate of the
maximum inventory of hazardous wastes ever on site during the active life of
the facility and a detailed description of the methods you shall use during
partial and final closure, such as methods for removing, transporting,
treating, storing, or disposing of all hazardous wastes and identification of
the types of off-site hazardous waste management units to be used, if
applicable.
(d) A detailed
description of the steps necessary to remove or decontaminate all hazardous
waste residues and contaminated containment system components, equipment,
structures, and soils during partial or final closure. These steps may include
procedures for cleaning equipment and removing contaminated soils, methods for
sampling and testing surrounding soils, and criteria for determining the extent
of decontamination required to satisfy the closure performance
standards.
(e) A detailed
description of other activities necessary during the closure period to ensure
that partial or final closure satisfies the closure performance
standards.
(f) A schedule for
closure of each hazardous waste management unit and for final closure of the
facility. The schedule shall include, at a minimum, the total time required to
close each hazardous waste management unit and the time required for
intervening closure activities that allow tracking of progress of partial or
final closure.
(g) For facilities
that use trust funds to establish financial assurance under s.
NR 667.0143 and that are expected to close prior to the
expiration of the license, an estimate of the expected year of final
closure.
(3) You may submit a written notification to the department for a license modification to amend the closure plan at any time prior to the notification of partial or final closure of the facility, following the applicable procedures in s. NR 670.320.
(a) Events
leading to a change in the closure plan, and therefore requiring a
modification, may include:
1. A change in the
operating plan or facility design.
2. A change in the expected year of closure,
if applicable.
3. In conducting
partial or final closure activities, an unexpected event requiring a
modification of the approved closure plan.
(b) The written notification or request shall
include a copy of the amended closure plan for review or approval by the
department. The department shall approve, disapprove, or modify the amended
plan according to the procedures in s.
NR 670.320.
(4) Notification before final closure.
(a) Notify the department in writing at least
45 days before the date that you expect to begin final closure of a treatment
or storage tank, container storage area, or containment building.
(b) The date when you expect to begin closure
shall be no later than 30 days after the date that any hazardous waste
management unit receives the known final volume of hazardous wastes.
(c) If your facility's license is terminated,
or if you are otherwise ordered, by the department, or required by judicial
decree or final order under
42 USC 6928
to cease receiving hazardous wastes or to close then the requirements of this
subsection do not apply. However, you shall close the facility following the
deadlines established in s.
NR 667.0115 unless earlier deadlines are set in a
department order, judicial decree, or final order under
42 USC
6928.
