§ 65.145 Nonflare control devices used to control emissions from storage vessels or low-throughput transfer racks.

(a) Nonflare control device equipment and operating requirements. The owner or operator shall operate and maintain the nonflare control device, including a halogen reduction device for a low-throughput transfer rack, so that the monitored parameters defined as required in paragraph (c) of this section remain within the ranges specified in the Initial Compliance Status Report whenever emissions of regulated material are routed to the control device and halogen reduction device, except during periods of startup, shutdown, and malfunction as specified in § 65.3(a).

(b) Nonflare control device design evaluation or performance test requirements. When using a control device other than a flare, the owner or operator shall comply with the requirements in paragraph (b)(1)(i), (ii), or (iii) of this section except as provided in paragraph (b)(2) of this section. Owners or operators of halogenated low-throughput transfer rack vent streams routed to a combustion device and then to a halogen reduction device to meet the specifications of § 65.83(b)(1), must also meet the requirements of paragraph (b)(3) of this section.

(1) Unless a design evaluation or performance test as required in the referencing subpart was previously conducted and submitted for the storage vessel or low-throughput transfer rack, the owner or operator shall either prepare and submit with the Initial Compliance Status Report, as specified in § 65.165(b), a design evaluation that includes the information specified in paragraph (b)(1)(i) of this section, or the results of the performance test as described in paragraph (b)(1)(ii) or (iii) of this section.

(i) Design evaluation. The design evaluation shall include documentation demonstrating that the control device being used achieves the required control efficiency during the reasonably expected maximum storage vessel filling or transfer loading rate. This documentation is to include a description of the gas stream that enters the control device, including flow and regulated material content; and additionally for storage vessels, the effects of varying liquid level conditions; and the information specified in paragraphs (b)(1)(i)(A) through (E) of this section, as applicable. This documentation shall be submitted with the Initial Compliance Status Report as specified in § 65.165(b).
