Sample Questions

Question 1

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

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 2

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

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

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

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 4

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

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?

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.
