Leak-rate thresholds, repair deadlines, extensions and records.

The question

The owner of a 300-pound R-22 chiller must calculate the leak rate every time refrigerant is added, except when the addition:

• Ais less than 5 pounds
• Bis made by the owner's own technician
• Cis made in the first month of the calendar year
• Dfollows a retrofit or is a seasonal varianceCorrect answer

Why “follows a retrofit or is a seasonal variance” is correct

The leak rate must be calculated after every addition unless it is made immediately after a retrofit, at installation of a new appliance, or qualifies as a seasonal variance. No size or staffing exception exists.

Source: 40 CFR 82.157(b); 40 CFR 82.152

Why the other answers are wrong

• is less than 5 pounds — No minimum amount exempts an addition from the calculation.
• is made by the owner's own technician — Who does the work does not matter.
• is made in the first month of the calendar year — The calendar month has nothing to do with it.
