# §65.153. Absorbers, condensers, carbon adsorbers, and other recovery devices used as final recovery devices.

- (a) **Final recovery device equipment and operating requirements.**
  - (1) Owners or operators using a recovery device to meet the requirement to operate and maintain a TRE above 1.0 as specified in [§ 65.63(a)(3)](/cfr/40/65.63.md?p=a-3) for process vents shall meet the requirements of this section.
  - (2) Recovery devices used to comply with the provisions of this subpart shall be operated at all times when emissions are vented to them.
- (b) **Recovery device performance test requirements.**
  - (1) **There are no performance test requirements for recovery devices.** Records of TRE index value determination shall be generated as specified in [§ 65.160(c)](/cfr/40/65.160.md?p=c).
  - (2) **Replace a final recovery device or control device.** Unless already permitted by the applicable title V permit, if an owner or operator elects to use a recovery device to replace an existing final recovery or control device at a later date, the owner or operator shall notify the Administrator, either by amendment of the regulated source's title V permit or, if title V is not applicable, by submission of the notice specified in [§ 65.167(a)](/cfr/40/65.167.md?p=a) before implementing the change. Upon implementing the change, the owner or operator shall comply with the applicable provisions of §§ [65.63(e)](/cfr/40/65.63.md?p=e) and [65.67(b)](/cfr/40/65.67.md?p=b).
- (c) **Recovery device monitoring requirements.**
  - (1) Where an absorber is the final recovery device in the recovery system and the TRE index value is between 1.0 and 4.0, either an organic monitoring device capable of providing a continuous record, or a scrubbing liquid temperature monitoring device and a specific gravity monitoring device, each capable of providing a continuous record, shall be used. Monitoring results shall be recorded as specified in [§ 65.161](/cfr/40/65.161.md). General requirements for monitoring and continuous parameter monitoring systems are contained in [§ 65.156](/cfr/40/65.156.md).
  - (2) Where a condenser is the final recovery device in the recovery system and the TRE index value is between 1.0 and 4.0, an organic monitoring device capable of providing a continuous record, or a condenser exit (product side) temperature monitoring device capable of providing a continuous record, shall be used. Monitoring results shall be recorded as specified in [§ 65.161](/cfr/40/65.161.md). General requirements for monitoring and continuous parameter monitoring systems are contained in [§ 65.156](/cfr/40/65.156.md).
  - (3) Where a carbon adsorber is the final recovery device in the recovery system and the TRE index value is between 1.0 and 4.0, an organic monitoring device capable of providing a continuous record, or an integrating regeneration stream flow monitoring device having an accuracy of ±10 percent or better capable of recording the total regeneration stream mass or volumetric flow for each regeneration cycle, and a carbon-bed temperature monitoring device capable of recording the carbon-bed temperature after each regeneration and within 15 minutes of completing any cooling cycle, shall be used. Monitoring results shall be recorded as specified in [§ 65.161](/cfr/40/65.161.md). General requirements for monitoring and continuous parameter monitoring systems are contained in [§ 65.156](/cfr/40/65.156.md).
  - (4) Unless previously approved by the Administrator under an applicable standard prior to the implementation date of this part, as specified in [§ 65.1(f)](/cfr/40/65.1.md?p=f), if an owner or operator uses a recovery device other than those listed in this subpart, the owner or operator shall submit a description of planned monitoring, reporting and recordkeeping procedures as required under [§ 65.162(e)](/cfr/40/65.162.md?p=e). The Administrator will approve or deny the proposed monitoring, reporting and recordkeeping requirements as part of the review of the submission or permit application or by other appropriate means.
  - (5) The owner or operator shall establish a range for monitored parameters that indicates proper operation of the recovery device. In order to establish the range, the information required in [§ 65.165(c)](/cfr/40/65.165.md?p=c) shall be submitted in the Initial Compliance Status Report or the operating permit application or amendment. The range may be based upon a prior performance test meeting the specifications in [§ 65.157(b)(1)](/cfr/40/65.157.md?p=b-1) or upon existing ranges or limits established under a referencing subpart. Where the regeneration stream flow and carbon-bed temperature are monitored, the range shall be in terms of the total regeneration stream flow per regeneration cycle, and the temperature of the carbon-bed determined within 15 minutes of the completion of the regeneration cooling cycle.
