A commercial supermarket rack system contains more than 50 pounds of refrigerant and develops a leak. Once the owner exceeds the applicable annual leak rate, the leak generally must be repaired within:
Explanation
For appliances containing 50 or more pounds of a class I or class II refrigerant, leaks that exceed the applicable annual leak rate threshold must generally be repaired within 30 days of discovery (40 CFR §82.157). A 24-hour or 7-day deadline is stricter than the rule requires, and 90 days is too long. If repairs cannot be completed in time, the owner may need a retrofit or retirement plan. The 30-day window is the same under the separate HFC leak-repair rule, 40 CFR §84.106, which has applied since January 1, 2026.
