  1. 10 percent per year
  2. 30 percent per year
  3. 20 percent per year ✔

Why: Commercial refrigeration, like supermarket and cold storage systems, must be repaired if it leaks at a rate over 20 percent a year. Comfort cooling is 10 percent and industrial process is 30 percent. These apply to ozone-depleting refrigerant in 50+ lb systems.

Huh, didn't know that: Retail food and cold storage warehouse equipment both count as commercial refrigeration.
