Once a covered appliance's leak rate is identified as exceeding its applicable repair trigger, what is the classic Section 608 timeframe historically taught for completing the repair?
Not quite. The answer is D: 30 days
Once refrigerant is added to an appliance whose leak rate exceeds its trigger, the owner has 30 days (120 days if an industrial process shutdown is required) to find and repair the leaks, with a certified technician doing the leak inspection. The owner can instead elect to retrofit or retire the appliance under a written plan, completed within one year. Limited extensions exist (for example, parts that are not available), but they require documentation and a request to EPA. The same 30-day clock also applies under the AIM Act rule for HFC appliances (40 CFR 84.106).

Checked against the official text
Read the eCFR text current through 2026-10-30 of § 82.157. (d): identify and repair leaks within 30 days (120 days if an industrial process shutdown is required) of the addition that shows the leak rate exceeded; (e): initial and follow-up verification tests; (h): retrofit/retirement plan within 30 days if not repairing.
