# §84.27. Controlling emissions of HFC-23.

- (a) No later than October 1, 2022, as compared to the amount of chemical intentionally produced on a facility line, no more than 0.1 percent of HFC-23 created on the line may be emitted.
  - (1) **Requests for extension.** The producer may submit a request to the relevant Agency official to request a six-month extension, with a possibility of one additional six-month extension, to meet the 0.1 percent HCFC-23 limit. No entity may have a compliance date later than October 1, 2023.
  - (2) **Timing of request.** The extension request must be submitted to EPA no later than August 1, 2022, for a first-time extension or February 1, 2023, for a second extension.
  - (3) **Content of request.** The extension request must contain the following information:
    - (i) Name of the facility submitting the request, contact information for a person at the facility, and the address of the facility.
    - (ii) A description of the specific actions the facility has taken to improve their HFC-23 control, capture, and destruction; the facility's plans to meet the 0.1 percent HFC-23 limit including the expected date by which the equipment will be installed and operating; and verification that the facility has met all applicable reporting requirements.
  - (4) **Review of request.** Starting on the first working day following receipt by the relevant Agency official of a complete request for extension, the relevant Agency official will initiate review of the information submitted under [paragraph (a)(3)](#a-3) of this section and take action within 30 working days. Any grant of a compliance deferral by the relevant Agency official will be made public.
- (b) **Captured HFC-23 is permitted to be destroyed at a different facility than where it is produced.** In such instances, HFC-23 emissions during the transportation to and destruction at the different facility will be incorporated into calculations of whether the producer meets the 0.1 percent standard outlined in [paragraph (a)](#a) of this section.
