Question 1

What is the legal definition of 'recovery' in the context of EPA 608 refrigerant handling?

Accepted Answer

Recovery is the process of removing refrigerant from a system in any condition and storing it in an external container, without necessarily testing or processing it.

Question 2

What is the difference between 'recycling' and 'reclamation' of refrigerant?

Accepted Answer

Recycling reduces contaminants using oil separation and single or multiple passes through filter-driers, typically on-site. Reclamation reprocesses refrigerant to AHRI 700 purity standards, which requires laboratory analysis and must be done at an EPA-certified facility.

Question 3

Under EPA Section 608, it is illegal to knowingly vent which types of refrigerants into the atmosphere?

Accepted Answer

It is illegal to knowingly vent CFC, HCFC, and HFC refrigerants. Only certain substitutes such as approved HFOs may be vented under specific conditions.

Question 4

Which federal law established the requirement to recover refrigerants and prohibits their intentional venting?

Accepted Answer

Section 608 of the Clean Air Act, as amended in 1990, established these requirements.

Question 5

What does the EPA consider 'de minimis' releases of refrigerant?

Accepted Answer

De minimis releases are small, incidental releases that occur during normal good-faith attempts to recover refrigerant, such as the small amount released when disconnecting hoses. These are not subject to penalty.
