  - (2) The disposable cylinder was used in the servicing, repair, or installation of refrigerant-containing equipment or fire suppression equipment; and
  - (3) The person does not intend to use the disposable cylinder in future servicing, repair, or installation of refrigerant-containing equipment or fire suppression equipment.
- (b) Except as provided in paragraphs [(e)](#e) and [(g)](#g) in this section, disposable cylinders that meet the criteria in paragraphs [(a)(1)](#a-1), [(a)(2)](#a-2), and [(a)(3)](#a-3) of this section must be sent to:
  - (1) A reclaimer certified under [40 CFR 82.164](/cfr/40/82.164.md);
  - (2) A fire suppressant recycler, if the disposable cylinder was used in the servicing, repair, or installation of fire suppression equipment;
  - (3) A final processor, such as a landfill operator or a scrap metal recycler, who is capable of removing the heel from disposable cylinders; or
  - (4) A refrigerant supplier (including but not limited to distributors and wholesalers), who is capable of removing the heel from disposable cylinders.
- (c) Regulated substance(s) removed from heels of disposable cylinders by those entities identified in paragraphs [(b)(3)](#b-3) and [(b)(4)](#b-4) of this section, where those removed heels are or are not aggregated into a larger container, must be sent to a reclaimer certified under [40 CFR 82.164](/cfr/40/82.164.md) or a fire suppressant recycler.
  - (1) Regulated substance(s) removed from heels of disposable cylinders that exhibit ignitability characteristics (per [40 CFR 261.21](/cfr/40/261.21.md)), where those removed heels are or are not aggregated into a larger container, must be sent to a reclaimer certified under [40 CFR 82.164](/cfr/40/82.164.md) that is in compliance with the requirements at [40 CFR part 266](/cfr/40/part266.md), subpart Q.

- (e) Disposable cylinders that that meet the criteria in paragraphs [(a)(1)](#a-1), [(a)(2)](#a-2), and [(a)(3)](#a-3) of this section may be discarded to a final processor without meeting the requirements in paragraphs [(b)](#b) and [(d)](#d) of this section, when:
  - (1) The heel was removed by a certified technician;
  - (2) The heel of the used disposable cylinder has been evacuated to a vacuum of 15 in-Hg prior to discarding the cylinder;
  - (3) The certified technician provides a certification statement, which certifies that the heel was evacuated to a vacuum of 15 in-Hg; states the name and address of the certified technician who evacuated the cylinder(s) and the date the cylinder(s) was/were evacuated; and is signed by the certified technician who evacuated the cylinder(s); and
  - (4) The certified technician discarding the cylinder to the final processor must provide the signed certification statement described in [paragraph (e)(3)](#e-3) of this section to the final processor (which may include a landfill operator or scrap metal recycler) when they discard the cylinder to the final processor.
- (f) **Recordkeeping.** A final processor who receives a disposable cylinder as described in [paragraph (e)](#e) of this section must maintain a record of the signed statement for three years.
