Ohio Administrative Code › Title 3745 - Ohio Environmental Protection Agency › Chapter 3745-51 - Identification and Listing of Hazardous Waste › Section 3745-51-787 - Closed-vent systems and control devices - tanks and containers

Current through all regulations passed and filed through July 1,
			 2024
(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
			 remanufacturer or other person who stores or treats the hazardous secondary
			 material 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 remanufacturer or other person who stores or treats the hazardous
			 secondary material in accordance with the procedure specified in paragraph (L)
			 of rule 3745-51-733 of the
			 Administrative Code.
