(A) This rule applies to each closed-vent system and control device installed and operated by the remanufacturer or other person who stores or treats the hazardous secondary material to control air emissions in accordance with standards of rules 3745-51-780 to 3745-51-789 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 secondary material in the hazardous
secondary material 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
3745-51-733 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
