  1. The EPA's 'de minimis' exemption under Section 608 allows venting refrigerant only when:

    Answer: The amount released is considered too small to require recovery equipment use

    The de minimis exemption covers incidental releases unavoidable during good-faith recovery efforts, not intentional venting of any recoverable amount.

  2. Which organization sets the standards for DOT cylinders used to store recovered refrigerants, including pressure ratings and test intervals?

    Answer: Department of Transportation (DOT)

    DOT regulates the design, testing, labeling, and re-qualification intervals for all compressed gas cylinders used in transport and storage.

  3. A recovery cylinder should never be filled beyond what percentage of its rated capacity by weight?

    Answer: 80%

    Filling a recovery cylinder above 80% of its rated capacity creates a risk of hydrostatic pressure buildup as liquid refrigerant expands with temperature rise.

  4. Foam insulation in older refrigerators may contain blowing agents such as CFC-11. During recycling, this foam should be:

    Answer: Processed through a foam-shredding system with gas capture to recover the blowing agent

    EPA regulations require that CFC blowing agents trapped in foam be captured during shredding rather than released into the atmosphere.

  5. What label information is REQUIRED on a recovery cylinder used to store mixed or unknown refrigerants?

    Answer: 'Mixed/Unknown Refrigerants – Do Not Mix' with date and technician info

    Proper labeling of unknown or mixed refrigerant cylinders prevents cross-contamination and ensures downstream reclaimers can handle or dispose of the contents correctly.

  6. Under EPA Section 608, intentionally venting a regulated refrigerant during appliance recycling can result in a civil penalty of up to how much per day, per violation?

    Answer: $44,539

    EPA's maximum civil penalty for violating Section 608 venting prohibitions is adjusted annually for inflation and can reach tens of thousands of dollars per day per violation.
