Before selling it to a different owner, what must happen to it?

Section 608 regulations · EPA 608 Core. The correct answer, and the reasoning behind it.

Pressure classes, recovery equipment certification, AHRI 700, the sales restriction and the venting ban.

The question

A contractor recovers 20 pounds of R-22 from a customer's system. Before selling it to a different owner, what must happen to it?

• AIt must be reclaimed by an EPA-certified reclaimerCorrect answer
• BIt must be filtered through a recycling machine
• CIt must be stored for at least 30 days
• DIt must be mixed with fresh R-22 first

Why “It must be reclaimed by an EPA-certified reclaimer” is correct

Under 40 CFR 82.154(d), used refrigerant may not be sold to a new owner unless it has been reclaimed by a reclaimer certified under 82.164 (with narrow exceptions such as transfers within the same company). Recycling alone is not enough.

Why the other answers are wrong

• It must be filtered through a recycling machine — Recycled refrigerant may go back only into equipment of the same owner.
• It must be stored for at least 30 days — Storage time does not change the reclamation requirement.
• It must be mixed with fresh R-22 first — Mixing with new refrigerant does not make used refrigerant legal to sell.
