(A) All containment
buildings shall comply with all of the following design standards:
(1) The containment building 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
man-made materials of sufficient strength
and thickness to support the materials, 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
they
such floors 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
it
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
paragraphs
paragraph
(A)
to (A)(4) 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 both of these criteria:
(a) The light-weight 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 fashion 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 the incompatible hazardous wastes or treatment reagents
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
that
contain 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 prevent 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 to minimize hydraulic head on the containment system
at the earliest practicable time that protects human health and the
environment.
(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
1x10-2
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
3x10-5
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 can serve as secondary containment systems for tanks placed within
the building under certain conditions. A containment building can serve as an
external liner system for a tank, provided the containment building complies
with paragraph (E)(1) of rule
3745-66-93
of the Administrative Code. In addition, the containment building shall comply
with paragraphs (B) and (C) of rule
3745-66-93
of the Administrative Code to be considered an acceptable secondary containment
system for a tank.
[Comment: Containment buildings can
serve as secondary containment systems for tanks placed within the building
under certain conditions. A containment building can serve as an external liner
system for a tank, provided the containment building complies with paragraph
(E)(1) of rule
3745-66-93
of the Administrative Code. In addition, the containment building shall comply
with paragraphs (B) and (C) of rule
3745-66-93
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 of rules
3745-256-100
to
3745-256-102
of the Administrative Code. In making this demonstration, the owner or operator
shall do all of the following:
(a) Provide
written notice to the director of the owner's or operator's request. This
notification shall describe the unit and
its
the unit's
operating 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 do all of the following:
(1)
Use controls and practices to ensure containment of the hazardous waste within
the unit, and, at a minimum:
(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. In addition, all associated particulate collection
devices (e.g., fabric filter, electrostatic precipitator) shall be operated and
maintained with sound air pollution control practices. This state of no visible
emissions shall be maintained effectively at all times during normal operating
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, if the owner or operator detects a condition
that could lead to or has caused a release of hazardous waste, the owner or
operator shall repair the condition promptly, 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 all of 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 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
have been
were
completed according to the written plan submitted in accordance with paragraph
(C)(3)(a)(iv) of this rule.
(4)
Inspect
At least once every
seven days, inspect and record in the facility's operating record
, at least once every seven days, 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 and without secondary containment, the owner or
operator shall do all of 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
log
record a written description of the operating
procedures used to maintain the integrity of areas without secondary
containment.
(E)
Notwithstanding any other provision of rules
3745-256-100
to
3745-256-102
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.
