Current through all regulations passed and filed through March 18, 2024
(A) All containment
buildings shall comply with the following design standards:
(1) The containment buildings shall be
completely enclosed with a floor, walls, and a roof to prevent exposure to the
elements (e.g., precipitation, wind, run-on), and to assure containment of
managed wastes.
(2) The floor and
containment walls of the unit, including the secondary containment system if
required under paragraph (B) of this rule, shall be designed and constructed of
materials of sufficient strength
and thickness to support such floor and walls, the waste contents, and any
personnel and heavy equipment that operate within the unit, and to prevent
failure due to pressure gradients, settlement, compression, uplift, physical
contact with the wastes to which such floor and walls are exposed, climatic
conditions, and the stresses of daily operation (including the movement of
heavy equipment within the unit and contact of such equipment with containment
walls). The unit shall be designed so that the unit has sufficient structural
strength to prevent collapse or other failure. All surfaces to be in contact
with hazardous wastes shall be chemically compatible with those wastes. Ohio
EPA will consider standards established by professional organizations generally
recognized by the industry such as the American concrete institute (ACI) and
the American society of testing materials (ASTM) in judging the structural
integrity requirements of paragraph (A) of this rule. If appropriate to the nature of the waste
management operation to take place in the unit, an exception to the structural
strength requirement may be made for light-weight doors and windows that meet
the following criteria:
(a) The doors and
windows provide an effective barrier against fugitive dust emissions under
paragraph (C)(1)(d) of this rule.
(b) The unit is designed and operated in a
manner that assures that wastes will not actually come in contact with these
openings.
(3)
Incompatible hazardous wastes or treatment reagents shall not be placed in the
unit or the unit's secondary containment system if such substances could cause
the unit or secondary containment system to leak, corrode, or otherwise
fail.
(4) A containment building
shall have a primary barrier designed to withstand the movement of personnel,
waste, and handling equipment in the unit during the operating life of the unit
and appropriate for the physical and chemical characteristics of the waste to
be managed.
(B) For a
containment building used to manage hazardous wastes containing free liquids or
treated with free liquids (the presence of which is determined by the paint
filter test, a visual examination, or other appropriate means), the owner or
operator shall include all of the following:
(1) A primary barrier designed and
constructed of materials to prevent the migration of hazardous constituents
into the barrier (e.g., a geomembrane covered by a concrete wear
surface).
(2) A liquid collection
and removal system to minimize the accumulation of liquid on the primary
barrier of the containment building.
(a) The
primary barrier shall be sloped to drain liquids to the associated collection
system.
(b) Liquids and waste shall
be collected and removed at the earliest practicable time to minimize hydraulic
head on the containment system.
(3) A secondary containment system including
a secondary barrier designed and constructed to prevent migration of hazardous
constituents into the barrier, and a leak detection system that is capable of
detecting failure of the primary barrier and collecting accumulated hazardous
wastes and liquids at the earliest practicable time.
(a) The requirements of the leak detection
component of the secondary containment system are satisfied by installation of
a system that is, at a minimum, both:
(i)
Constructed with a bottom slope of one per cent or more.
(ii) Constructed of a granular drainage
material with a hydraulic conductivity of 1 x 10-2
centimeters per second or more and a thickness of twelve inches (30.5
centimeters) or more, or constructed of synthetic or geonet drainage materials
with a transmissivity of 3 x 10-5 meters squared per
second or more.
(b) If
treatment is to be conducted in the building, an area in which such treatment
will be conducted shall be designed to prevent the release of liquids, wet
materials, or liquid aerosols to other portions of the building.
(c) The secondary containment system shall be
constructed of materials that are chemically resistant to the waste and liquids
managed in the containment building and of sufficient strength and thickness to
prevent collapse under the pressure exerted by overlaying materials and by any
equipment used in the containment building. Containment
buildings may serve as secondary containment systems for tanks placed within
the building under certain conditions. A containment building may serve as an
external liner system for a tank, provided the containment building complies
with paragraph (E)(1) of rule
3745-55-93
of the Administrative Code. In addition, the containment building shall comply
with paragraphs (B), (C)(1), and (C)(2) of rule
3745-55-93
of the Administrative Code to be considered an acceptable secondary containment
system for a tank.
(4) For existing units other than ninety-day
generator units, the director may delay the secondary containment requirement
for up to two years, based on a demonstration by the owner or operator that the
unit substantially meets the standards in rules
3745-205-100
to
3745-205-102
of the Administrative Code. In making this demonstration, the owner or operator
shall do the following:
(a) Provide written
notice to the director of the owner's or operator's request. This notification
shall describe the unit and the unit'soperating practices with specific reference
to the performance of existing containment systems, and specific plans for
retrofitting the unit with secondary containment.
(b) Respond within thirty days to any
comments from the director on these plans.
(c) Fulfill the terms of the revised plans if
such plans are approved by the director.
(C) Owners or operators of all containment
buildings shall:
(1) Use controls and
practices to ensure containment of the hazardous waste within the unit, and, at
a minimum, do all of the following:
(a)
Maintain the primary barrier to be free of significant cracks, gaps, corrosion,
or other deterioration that could cause hazardous waste to be released from the
primary barrier.
(b) Maintain the
level of the stored or treated hazardous waste within the containment walls of
the unit so that the height of any containment wall is not exceeded.
(c) Take measures to prevent the tracking of
hazardous waste out of the unit by personnel or by equipment used in handling
the waste. An area shall be designated to decontaminate equipment, and any
rinsate shall be collected and properly managed.
(d) Take measures to control fugitive dust
emissions such that any openings (doors, windows, vents, cracks, etc.) exhibit
no visible emissions (see method 22 in appendix A to 40 CFR Part 60
, visual determination of fugitive emissions from
material sources and smoke emissions from flares). In addition, all associated
particulate collection devices (e.g., fabric filter, electrostatic
precipitator) shall be operated and maintained with sound air pollution control
practices (see 40 CFR Part 60 subpart 292 for
guidance). This state of no visible emissions shall be maintained
effectively at all times during routine operating and maintenance conditions,
including when vehicles and personnel are entering and exiting the
unit.
(2) Obtain and keep
on-site a certification by a qualified professional engineer that the
containment building design complies with paragraphs (A) to (C)(4) of this
rule.
(3) Throughout the active
life of the containment building, repair promptly upon detection any condition
that could lead to or has caused a release of hazardous waste, in accordance
with the following procedures:
(a) Upon
detection of a condition that has led to a release of hazardous waste (e.g.,
upon detection of leakage from the primary barrier), the owner or operator
shall do the following:
(i) Enter a record of
the discovery in the facility operating record.
(ii) Immediately remove from service the
portion of the containment building affected by the condition.
(iii) Determine what steps shall be taken to
repair the containment building, remove any leakage from the secondary
collection system, and establish a schedule for accomplishing the cleanup and
repairs.
(iv) Within seven days
after the discovery of the condition, notify the director of the condition, and
within fourteen working days, provide a written plan to the director with a
description of the steps taken to repair the containment building, and with the schedule for accomplishing the
work.
(b) The director
will review the information submitted,
make a determination regarding whether the containment building shall be
completely or partially removed from service
until repairs and
cleanup are complete, and notify the
owner or operator in writing of the determination and the underlying
rationale.
(c) Upon completing all
repairs and cleanup, the owner or operator shall notify the director in writing
and provide a verification, signed by a qualified,
registered professional engineer, that the repairs and cleanup
were
completed according to the written plan submitted in accordance with paragraph
(C)(3)(a)(iv) of this rule.
(4)
At least once every
seven days, inspect and record in the facility's operating record data gathered
from monitoring equipment, leak detection equipment, the containment building,
and the area that immediately surrounding the
containment building, to detect signs of releases of hazardous waste.
(D) For a containment building
that contains both areas with secondary containment and without secondary
containment, the owner or operator shall do the following:
(1) Design and operate each area in
accordance with paragraphs (A) to (C)(4) of this rule.
(2) Take measures to prevent the release of
liquids or wet materials into areas without secondary containment.
(3) Maintain in the facility's operating
record a written description of the operating procedures used to maintain the
integrity of areas without secondary containment.
(E) Notwithstanding any other provisions of
rules
3745-205-100
to
3745-205-102
of the Administrative Code, the director may waive requirements for secondary
containment for a permitted containment building where the owner or operator
demonstrates that the only free liquids in the unit are limited amounts of dust
suppression liquids required to meet occupational health and safety
requirements, and where containment of managed wastes and liquids can be
assured without a secondary containment system.
