Current through Register Vol. 48, No. 6, June 28, 2024
(a) This section 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 this subpart.
(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
				  section.
(2) The closed-vent system
				  shall be designed and operated in accordance with the requirements specified in
				  section 261.1033(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 paragraph (b)(3)(i) of this section or a seal or locking device as
				  specified in paragraph (b)(3)(ii) 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.
(i) If a flow indicator is used to comply
				  with paragraph (b)(3) of this section, 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) of this section, 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 that
				  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 that stores or treats the
				  hazardous secondary material in accordance with the procedure specified in
				  section 261.1033(l).
