Utah Admin. Code R315-265-1101 - Containment Buildings - Design and Operating Standards
(a) Each containment building shall comply
with 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, for example, 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 by Subsection
R315-265-1101(b), shall be designed and constructed of materials of sufficient
strength and thickness to support themselves, the waste contents, and any
personnel and heavy equipment that operate within the unit, and to prevent
failure due to pressure gradients, settlement, compression, or uplift, physical
contact with the hazardous wastes to which they are exposed, climatic
conditions, and the stresses of daily operation, including the movement of
heavy equipment within the unit and contact of that equipment with containment
walls. The unit shall be designed so that it has sufficient structural strength
to prevent collapse or other failure. Each surface to be in contact with
hazardous wastes shall be chemically compatible with those wastes. The director
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 Subsection R315-265-1101(a)(2). 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 these criteria:
(i) they provide an effective barrier against
fugitive dust emissions in accordance with Subsection R315-265-1101(c)(1)(iv);
and
(ii) the unit is designed and
operated in a fashion that assures that wastes will not contact these
openings.
(3)
Incompatible hazardous wastes or treatment reagents shall not be placed in the
unit or its secondary containment system if they 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.
(1) A primary barrier
designed and constructed of materials to prevent the migration of hazardous
constituents into the barrier, for example, 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:
(i) the primary barrier shall be sloped to
drain liquids to the associated collection system; and
(ii) 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 can
detect failure of the primary barrier and collecting accumulated hazardous
wastes and liquids at the earliest practicable time.
(i) The requirements of the leak detection
component of the secondary containment system are satisfied by installation of
a system that is, at a minimum:
(A)
constructed with a bottom slope of 1 % or more; and
(B) constructed of a granular drainage
material with a hydraulic conductivity of 1 ×
10-2 cm per sec or more and a thickness of 12
inches, 30.5 cm, or more, or constructed of synthetic or geonet drainage
materials with a transmissivity of 3 × 10-5
m2 per sec or more.
(ii) If treatment is to be conducted in the
building, an area in which treatment will be conducted shall be designed to
prevent the release of liquids, wet materials, or liquid aerosols to other
portions of the building.
(iii) 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
it meets the requirements of Subsection
R315-265-193(e)(1).
In addition, the containment building shall meet the requirements of
Subsections
R315-265-193(b)
and (c) to be considered an acceptable
secondary containment system for a tank.
(4) For existing units other than 90-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 Sections R315-265-1100 through
R315-265-1102. In making this demonstration, the owner or operator shall:
(i) provide written notice to the director of
their request by February 18, 1993 that describes the unit and its operating
practices with specific reference to the performance of existing containment
systems, and specific plans for retrofitting the unit with secondary
containment;
(ii) respond to any
comments from the director on these plans within 30 days; and
(iii) fulfill the terms of the revised plans,
if those plans are approved by the director .
(c) Owners or operators of containment
buildings shall comply with the following.
(1)
Use controls and practices to ensure containment of the hazardous waste within
the unit, and, at a minimum:
(i) 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;
(ii) 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;
(iii) 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; and
(iv) take measures to control fugitive dust
emissions so that any openings, doors, windows, vents, cracks, exhibit no
visible emissions. In addition, each associated particulate collection device,
for example, 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 any time 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 meets the requirements of Subsections
R315-265-1101(a), (b), and (c).
(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.
(i)
Upon detection of a condition that has led to a release of hazardous waste , for
example, upon detection of leakage from the primary barrier, the owner or
operator shall:
(A) enter a record of the
discovery in the facility operating record;
(B) immediately remove the portion of the
containment building affected by the condition from service;
(C) 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; and
(D) within 7 days
after the discovery of the condition, notify the director of the condition, and
within 14 working days, provide a written notice to the director with a
description of the steps taken to repair the containment building, and the
schedule for accomplishing the work.
(ii) The director will review the information
submitted, make a determination regarding whether the containment building
shall be removed from service completely or partially until repairs and cleanup
are complete, and notify the owner or operator of the determination and the
underlying rationale in writing.
(iii) Upon completing the 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 completed according to the written plan submitted
in accordance with Subsection R315-265-1101(c)(3)(i)(D).
(4) Inspect and record in the facility 's
operating record at least once each seven days data gathered from monitoring
and leak detection equipment as well as the containment building and the area
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:
(1)
design and operate each area in accordance with the requirements enumerated in
Subsections R315-265-1101(a) through (c);
(2) take measures to prevent the release of
liquids or wet materials into areas without secondary containment;
and
(3) maintain in the facility 's
operating log a written description of the operating procedures used to
maintain the integrity of areas without secondary containment.
(e) Notwithstanding any other
provision of Sections R315-265-1100 through R315-265-1102, the director may
waive requirements for secondary containment for a permitted containment
building if 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 if containment of managed
wastes and liquids may be assured without a secondary containment
system.
