- 10 percent
- 20 percentCorrect answer
- 30 percent

Why “20 percent” is correct
Commercial refrigeration, meaning retail food and cold storage equipment, has a 20 percent trigger leak rate under Part 82. The rule applies here because the appliance holds 50 pounds or more of an HCFC.

- 35 percent — 35 percent was the old commercial and industrial rate that applied before 2019.
