Cal. Code Regs. Tit. 22, § 66265.1088 - Standards: Closed-Vent Systems and Control Devices
(a) This section 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 this article.
(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 (c) of this section.
(2) The closed-vent system shall be designed
and operated in accordance with the requirements specified in section
66265.1033(j).
(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 (b)(3)(A) of
this section or a seal or locking device as specified in subsection (b)(3)(B)
of this section. For the purpose of complying with this subsection, 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.
(A) If a flow indicator is used to comply
with subsection (b)(3) of this section, 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
this subsection, a flow indicator means a device which indicates the presence
of either gas or vapor flow in the bypass line.
(B) If a seal or locking device is used to
comply with subsection (b)(3) of this section, 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 section
66265.1033(k).
(c) The control device shall meet the
following requirements:
(1) The control
device shall be one of the following devices:
(A) 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;
(B) An enclosed combustion device designed
and operated in accordance with the requirements of section
66265.1033(c);
or
(C) A flare designed and
operated in accordance with the requirements of section
66265.1033(d).
(2) The owner or operator who elects to use a
closed-vent system and control device to comply with the requirements of this
section shall comply with the requirements specified in subsections (c)(2)(A)
through (c)(2)(F) of this section.
(A)
Periods of planned routine maintenance of the control device, during which the
control device does not meet the specifications of subsections (c)(1)(A),
(c)(1)(B), or (c)(1)(C) of this section, as applicable, shall not exceed 240
hours per year.
(B) The
specifications and requirements in subsections (c)(1)(A), (c)(1)(B), and
(c)(1)(C) of this section for control devices do not apply during periods of
planned routine maintenance.
(C)
The specifications and requirements in subsections (c)(1)(A), (c)(1)(B), and
(c)(1)(C) of this section for control devices do not apply during a control
device system malfunction.
(D) The
owner or operator shall demonstrate compliance with the requirements of
subsection (c)(2)(A) of this section (i.e., planned routine maintenance of a
control device, during which the control device does not meet the
specifications of subsections (c)(1)(A), (c)(1)(B), or (c)(1)(C) of this
section, as applicable, shall not exceed 240 hours per year) by recording the
information specified in section
66265.1090(e)(1)(E).
(E) 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.
(F) The owner or operator shall operate the
closed-vent system such that gases, vapors, and/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, 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 (c)(1) of
this section shall operate and maintain the control device in accordance with
the following requirements:
(A) 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 section
66265.1033(g) or
section 66265.1033(h).
(B) All carbon that is a hazardous waste and
that is removed from the control device shall be managed in accordance with the
requirements of section
66265.1033(m),
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 (c)(1) of this section shall operate and maintain the control device
in accordance with the requirements of section
66265.1033(i).
(5) The owner or operator shall demonstrate
that a control device achieves the performance requirements of subsection
(c)(1) of this section as follows:
(A) An
owner or operator shall demonstrate using either a performance test as
specified in subsection (c)(5)(C) of this section or a design analysis as
specified in subsection (c)(5)(D) of this section the performance of each
control device except for the following:
1. A
flare;
2. A boiler or process
heater with a design heat input capacity of 44 megawatts or greater;
3. A boiler or process heater into which the
vent stream is introduced with the primary fuel;
4. A boiler or industrial furnace burning
hazardous waste for which the owner or operator has been issued a final permit
under chapter 20 and has designed and operates the unit in accordance with the
requirements of chapter 16, article 8; or
5. A boiler or industrial furnace burning
hazardous waste for which the owner or operator has designed and operates in
accordance with the interim status requirements of chapter 16, article
8.
(B) An owner or
operator shall demonstrate the performance of each flare in accordance with the
requirements specified in section
66265.1033(e).
(C) For a performance test conducted to meet
the requirements of subsection (c)(5)(A) of this section, the owner or operator
shall use the test methods and procedures specified in section
66265.1034(c)(1) through
(c)(4).
(D) For a design analysis conducted to meet
the requirements of subsection (c)(5)(A) of this section, the design analysis
shall meet the requirements specified in section
66265.1035(b)(4)(C).
(E) The owner or operator shall demonstrate
that a carbon adsorption system achieves the performance requirements of
subsection (c)(1) of this section based on the total quantity of organics
vented to the atmosphere from all carbon adsorption system equipment that is
used for organic adsorption, organic desorption or carbon regeneration, organic
recovery, and carbon disposal.
(6) If the owner or operator and the
Department do not agree on a demonstration of control device performance using
a design analysis then the disagreement shall be resolved using the results of
a performance test performed by the owner or operator in accordance with the
requirements of subsection (c)(5)(C) of this section. The Department may choose
to have an authorized representative observe the performance test.
(7) The closed-vent system and control device
shall be inspected and monitored by the owner or operator in accordance with
the procedures specified in sections
66265.1033(f)(2)
and 66265.1033(k).

shall be inspected at least once each operating day to check control device
operation. Any necessary corrective measures shall be immediately implemented
to ensure the control device is operated in compliance with the requirements of
this section.
