3 Refrigerant Environmental Regulations and Compliance Free Online FlashCards

What environmental risks do CFCs, HCFCs, and many HFCs pose?

CFCs and HCFCs can deplete the ozone layer; many HFCs do not, but can have high global-warming potential.

What does Clean Air Act Section 608 regulate?

Section 608 regulates stationary refrigeration and air-conditioning work through certification, venting prohibitions, and recovery, leak-repair, sales, and recordkeeping requirements.

What are the AIM Act’s main approaches to HFCs?

The AIM Act phases down HFCs, restricts their use in specific sectors, and sets rules to reduce emissions and increase reclamation.

When does refrigerant work generally require Section 608 certification?

Certification is generally required for work reasonably expected to release refrigerant, such as attaching or detaching gauges or hoses, or adding or removing refrigerant.

What equipment does Universal Section 608 certification cover?

Type I, II, and III certifications cover specified equipment; Universal certification covers all types.

What is the de minimis venting exception during refrigerant recovery?

Technicians must recover refrigerant rather than intentionally vent it. A narrow de minimis exception covers small releases during good-faith recovery, such as normal hose connection or disconnection.

When may recovered refrigerant be sold for reuse?

Recovered refrigerant generally cannot be sold for reuse unless reclaimed by an EPA-certified reclaimer. Reuse may be allowed in equipment belonging to the same owner, subject to applicable requirements.

Which appliances are covered by Section 608 leak-repair provisions?

Section 608 leak-repair provisions apply to appliances with a full charge of at least 50 pounds of CFC or HCFC refrigerant; they do not apply under Section 608 to equipment containing only HFC substitutes.

What is the AIM Act leak-rule threshold and a key exception?

Effective January 1, 2026, the AIM Act rule covers certain appliances with at least 15 pounds of HFC or specified HFC-substitute refrigerant. Exceptions include residential and light-commercial air-conditioning and heat-pump equipment.

What leak-rate thresholds apply by equipment category?

The applicable thresholds are $30\%$ for industrial process refrigeration, $20\%$ for commercial refrigeration, and $10\%$ for comfort cooling and other covered categories.

How soon must excess leaks generally be repaired?

If the leak rate exceeds the applicable threshold, leaks generally must be identified and repaired within 30 days, or within 120 days if an industrial-process shutdown is required. Verification tests are also required.

What disposal records must technicians keep for appliances with 5 to 50 pounds of refrigerant?

For disposal of appliances containing 5 to 50 pounds of refrigerant, technicians record the recovery location and date, refrigerant type, monthly amounts recovered, and amounts transferred for reclamation or destruction; keep these records for three years.
