Ohio Admin. Code 3745-205-87 - Closed-vent systems and control devices - air emission standards for tanks, surface impoundments, and containers
(A)
This rule 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
rules 3745-205-80 to
3745-205-90 of the
Administrative Code.
(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 paragraph (C) of this
rule.
(2)
The closed-vent system shall be designed and operated
in accordance with the requirements specified in paragraph (K) of rule
3745-205-33 of the
Administrative Code.
(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 paragraph (B)(3)(a) of this rule or a
seal or locking device as specified in paragraph (B)(3)(b) of this rule. 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 paragraph
(B)(3) of this rule, 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.
(b)
If a seal or
locking device is used to comply with paragraph (B)(3) of this rule, 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
(4)
The closed-vent
system shall be inspected and monitored by the owner or operator in accordance
with the procedure specified in paragraph (L) of rule
3745-205-33 of the
Administrative Code.
(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 ninety-five per cent by
weight;
(b)
An enclosed combustion device designed and operated in
accordance with the requirements of paragraph (C) of rule
3745-205-33 of the
Administrative Code; or
(c)
A flare designed and operated in accordance with the
requirements of paragraph (D) of rule
3745-205-33 of the
Administrative Code.
(2)
The owner or
operator who elects to use a closed-vent system and control device to comply
with the requirements of this rule shall comply with the requirements specified
in paragraphs (C)(2)(a) to (C)(2)(f) of this rule.
(a)
Periods of
planned routine maintenance of the control device, during which the control
device does not meet the specifications of paragraph (C)(1)(a), (C)(1)(b), or
(C)(1)(c) of this rule, as applicable, shall not exceed two hundred forty hours
per year.
(b)
The specifications and requirements in paragraphs
(C)(1)(a), (C)(1)(b), and (C)(1)(c) of this rule for control devices do not
apply during periods of planned routine maintenance.
(c)
The
specifications and requirements in paragraphs (C)(1)(a), (C)(1)(b), and
(C)(1)(c) of this rule for control devices do not apply during a control device
system malfunction.
(d)
The owner or operator shall demonstrate compliance with
the requirements of paragraph (C)(2)(a) of this rule [i.e., planned routine
maintenance of a control device, during which the control device does not meet
the specifications of paragraph (C)(1)(a), (C)(1)(b), or (C)(1)(c) of this
rule, as applicable, shall not exceed two hundred forty hours per year] by
recording the information specified in paragraph (E)(1)(e) of rule
3745-205-89 of the
Administrative Code.
(e)
The owner or operator shall correct control device
system malfunctions as soon as practicable after the malfunction's 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, 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, 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 rule 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 paragraph (G) or (H) of rule
3745-205-33 of the
Administrative Code.
(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 paragraph (N) of rule
3745-205-33 of the
Administrative Code, regardless of the average volatile organic concentration
of the carbon.
(4)
