Section V-1761 - Standards: Closed-Vent Systems and Control Devices
Universal Citation: LA Admin Code V-1761
Current through Register Vol. 50, No. 9, September 20, 2024
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. 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. shall be designed and
operated in accordance with the requirements specified in LAC
33:V.1709.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
Subparagraph B.3.a of this Section or a seal or locking device as specified in
Subparagraph B.3.b of this Section. 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:
a. if a flow indicator is used to comply with
this Subsection, 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 that 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 this Subsection, 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. shall be
inspected and monitored by the owner or operator in accordance with the
procedure specified in LAC 33:V.1709.L.
C. The control device shall meet the following requirements:
1. 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 LAC 33:V.1709.C; or
c. a flare designed and operated in
accordance with the requirements of LAC 33:V.1709.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.a-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 Subparagraph C.1.a, b, or c of this Section, as
applicable, shall not exceed 240 hours per year;
b. the specifications and requirements in
Subparagraph C.1.a, b, or c of this Section for control devices do not apply
during periods of planned routine maintenance;
c. the specifications and requirements in
Subparagraph C.1.a, b, or 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 Subparagraph 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 Subparagraph C.1.a, b, or c of this
Section, as applicable, shall not exceed 240 hours per year) by recording the
information specified in LAC 33:V.1765.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;
and
f. 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 Paragraph 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 LAC 33:V.1709.G or H; and
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 LAC 33:V.1709.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 Paragraph C.1 of this
Section shall operate and maintain the control device in accordance with the
requirements of LAC 33:V.1709.J;
5.
the owner or operator shall demonstrate that a control device achieves the
performance requirements of Paragraph C.1 of this Section as follows:
a. an owner or operator shall demonstrate,
using either a performance test as specified in Subparagraph C.5.c of this
Section or a design analysis as specified in Subparagraph C.5.d of this
Section, the performance of each control device except for the following:
i. a flare;
ii. a boiler or process heater with a design
heat input capacity of 44 megawatts or greater;
iii. a boiler or process heater into which
the vent stream is introduced with the primary fuel;
iv. a boiler or industrial furnace burning
hazardous waste for which the owner or operator has been issued a final permit
under LAC 33:V.Chapter 5 and has designed and operates the unit in accordance
with the requirements of LAC 33:V.Chapter 30; or
v. 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 LAC 33:V.Chapter
30;
b. an owner or
operator shall demonstrate the performance of each flare in accordance with the
requirements specified in LAC 33:V.1709.E;
c. for a performance test conducted to meet
the requirements of Subparagraph C.5.a of this Section, the owner or operator
shall use the test methods and procedures specified in LAC
33:V.1711.C.1-4;
d. for a design
analysis conducted to meet the requirements of Subparagraph C.5.a of this
Section, the design analysis shall meet the requirements specified in LAC
33:V.1713.B.4.c; and
e. the owner
or operator shall demonstrate that a carbon adsorption system achieves the
performance requirements of Paragraph 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
administrative authority 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.c of this Section. The
administrative authority may choose to have an authorized representative
observe the performance test; and
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 LAC 33:V.1709.F.2 and L. The readings from each
monitoring device required by LAC 33:V.1709.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.
