The question

• A12 months
• B18 monthsCorrect answer
• C24 months
• D30 months

Why “18 months” is correct

Owners of any appliance type are automatically allowed 18 months to retire an appliance if the replacement uses a substitute refrigerant exempted under 82.154(a), such as certain natural refrigerants. Otherwise the plan schedule is one year.

• 24 months — 24 months is not a period named in this rule.
• 30 months — 30 months is not a period named in this rule.
