Haw. Code R. § 11-265-1088 - 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 subchapter.
(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).
(2) The closed-vent system shall be designed
and operated in accordance with the requirements specified in section
11-265-1033(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 subparagraph (b)(3)(i) or a seal or locking device as specified in
subparagraph (b)(3)(ii). For the purpose of complying with this paragraph, 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 paragraph (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 this paragraph,
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 paragraph (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 section 11-265-1033(k).
(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 section 11-265-1033(c);
or
(iii) A flare designed and
operated in accordance with the requirements of section
11-265-1033(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 subparagraphs (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 subparagraph (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
subparagraphs (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
subparagraph (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 subparagraph (c)(2)(i) (i.e., planned
routine maintenance of a control device, during which the control device does
not meet the specifications of subparagraphs (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 section 11-265-1090(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, 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 paragraph (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
section 11-265-1033(g) or 11-265-1033(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 section 11-265-1033(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 paragraph (c)(1) shall
operate and maintain the control device in accordance with the requirements of
section 11-265-1033(i).
(5) The
owner or operator shall demonstrate that a control device achieves the
performance requirements of paragraph (c)(1) as follows:
(i) An owner or operator shall demonstrate
using either a performance test as specified in subparagraph (c) (5) (iii) or a
design analysis as specified in subparagraph (c)(5)(iv) the performance of each
control device except for the following:
(A)
A flare;
(B) A boiler or process
heater with a design heat input capacity of 44 megawatts or greater;
(C) A boiler or process heater into which the
vent stream is introduced with the primary fuel;
(D) A boiler or industrial furnace burning
hazardous waste for which the owner or operator has:
(1) Been issued a final permit under 40 CFR
part 270 and has designed and operates the unit in accordance with the
requirements of chapter 11-266, subchapter H; or
(2) Been issued a State hazardous waste
management permit under chapter 11-270 and has designed and operates the unit
in accordance with the requirements of chapter 11-266, subchapter H;
or
(E) 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 11-266, subchapter H.
(ii) An owner or operator shall demonstrate
the performance of each flare in accordance with the requirements specified in
section 11-265-1033(e).
(iii) For a
performance test conducted to meet the requirements of subparagraph (c)(5)(i),
the owner or operator shall use the test methods and procedures specified in
sections 11-265-1034(c)(1) through (c) (4).
(iv) For a design analysis conducted to meet
the requirements of subparagraph (c)(5)(i), the design analysis shall meet the
requirements specified in section 11-265-1035(b)(4)(iii).
(v) The owner or operator shall demonstrate
that a carbon adsorption system achieves the performance requirements of
paragraph (c)(1) 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 director 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 subparagraph (c)(5)(iii). The
director 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
11-265-1033(f) (2) and 11-265-1033(k). The readings from each monitoring device
required by section 11-265-1033(f)(2) 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.
