Utah Admin. Code R315-264-1087 - Standards: Closed-Vent Systems and Control Devices
(a) Section R315-264-1087 applies to each
closed-vent system and control device installed and operated by the owner or
operator to control air emissions in accordance with standards of Sections
R315-264-1080
through 1090.
(b) The closed-vent
system shall meet the following requirements:
(1) The closed-vent system shall route the
gases, vapors, and fumes emitted from the hazardous waste in the waste
management unit to a control device that meets the requirements specified in
Subsection R315-264-1087(c).
(2)
The closed-vent system shall be designed and operated in accordance with the
requirements specified in Subsection
R315-264-1033(k).
(3) In the case when the
closed-vent system includes bypass devices that could be used to divert the gas
or vapor stream to the atmosphere before entering the control device, each
bypass device shall be equipped with either a flow indicator as specified in
Subsection R315-264-1087(b)(3)(i) or a seal or locking device as specified in
Subsection R315-264-1087(b)(3)(ii). For the purpose of complying with
Subsection R315-264-1087(b), low leg drains, high point bleeds, analyzer vents,
open-ended valves or lines, spring loaded pressure relief valves, and other
fittings used for safety purposes are not considered to be bypass devices.
(i) If a flow indicator is used to comply
with Subsection R315-264-1087(b)(3), the indicator shall be installed at the
inlet to the bypass line used to divert gases and vapors from the closed-vent
system to the atmosphere at a point upstream of the control device inlet. For
Subsection R315-264-1087(b), a flow indicator means a device which indicates
the presence of either gas or vapor flow in the bypass line.
(ii) If a seal or locking device is used to
comply with Subsection R315-264-1087(b)(3), the device shall be placed on the
mechanism by which the bypass device position is controlled, e.g., valve
handle, damper lever, when the bypass device is in the closed position such
that the bypass device cannot be opened without breaking the seal or removing
the lock. Examples of such devices include, but are not limited to, a car-seal
or a lock-and-key configuration valve. The owner or operator shall visually
inspect the seal or closure mechanism at least once every month to verify that
the bypass mechanism is maintained in the closed position.
(4) The closed-vent system shall
be inspected and monitored by the owner or operator in accordance with the
procedure specified in Subsection
R315-264-1033(l).
(c) The control device
shall meet the following requirements:
(1)
The control device shall be one of the following devices:
(i) A control device designed and operated to
reduce the total organic content of the inlet vapor stream vented to the
control device by at least 95 percent by weight;
(ii) An enclosed combustion device designed
and operated in accordance with the requirements of Subsection
R315-264-1033(c);
or
(iii) A flare designed and
operated in accordance with the requirements of Subsection
R315-264-1033(d).
(2) The owner or
operator who elects to use a closed-vent system and control device to comply
with the requirements of Section R315-264-1087 shall comply with the
requirements specified in Subsections R315-264-1087(c)(2)(i) through
(c)(2)(vi).
(i) Periods of planned routine
maintenance of the control device, during which the control device does not
meet the specifications of Subsections R315-264-1087(c)(1)(i), (c)(1)(ii), or
(c)(1)(iii), as applicable, shall not exceed 240 hours per year.
(ii) The specifications and requirements in
Subsections R315-264-1087(c)(1)(i), (c)(1)(ii), and (c)(1)(iii) for control
devices do not apply during periods of planned routine maintenance.
(iii) The specifications and requirements in
Subsections R315-264-1087(c)(1)(i), (c)(1)(ii), and (c)(1)(iii) for control
devices do not apply during a control device system malfunction.
(iv) The owner or operator shall demonstrate
compliance with the requirements of Subsection R315-264-1087(c)(2)(i), i.e.,
planned routine maintenance of a control device, during which the control
device does not meet the specifications of Subsections R315-264-1087(c)(1)(i),
(c)(1)(ii), or (c)(1)(iii), as applicable, shall not exceed 240 hours per year,
by recording the information specified in Subsection
R315-264-1089(e)(1)(v).
(v) The owner or operator shall
correct control device system malfunctions as soon as practicable after their
occurrence in order to minimize excess emissions of air pollutants.
(vi) The owner or operator shall operate the
closed-vent system such that gases, vapors, or fumes are not actively vented to
the control device during periods of planned maintenance or control device
system malfunction, i.e., periods when the control device is not operating or
not operating normally, except in cases when it is necessary to vent the gases,
vapors, and/or fumes to avoid an unsafe condition or to implement malfunction
corrective actions or planned maintenance actions.
(3) The owner or operator using a carbon
adsorption system to comply with Subsection R315-264-1087(c)(1) shall operate
and maintain the control device in accordance with the following requirements:
(i) Following the initial startup of the
control device, all activated carbon in the control device shall be replaced
with fresh carbon on a regular basis in accordance with the requirements of
Subsections
R315-264-1033(g)
or 1033(h).
(ii) All carbon that
is a hazardous waste and that is removed from the control device shall be
managed in accordance with the requirements of Subsection
R315-264-1033(n),
regardless of the average volatile organic concentration of the carbon.
(4) An owner or
operator using a control device other than a thermal vapor incinerator, flare,
boiler, process heater, condenser, or carbon adsorption system to comply with
Subsection R315-264-1087(c)(1) shall operate and maintain the control device in
accordance with the requirements of Subsection
R315-264-1033(j).
