EPA Clean Air Act rules permit refrigerant to be released to the atmosphere under which of the following conditions?

Correct Answer: Option A — when release is considered 'de minimis'

EPA Clean Air Act regulations prohibit the intentional venting of ozone-depleting and substitute refrigerants. The only legal allowance for release is under 'de minimis' quantities associated with normal, unavoidable minor losses during connection and disconnection of recovery equipment.
