According to the EPA Clean Air Act rules, what is true concerning refrigerant leaks in a small hermetically sealed shipboard water cooler with a 20 ounce charge weight?

Correct Answer: Option A — Legally, the leaks are not required to be repaired, but morally it is advisable to repair the leaks.

Federal regulations exempt small appliances containing under five pounds of refrigerant from mandatory leak repair requirements, making repairs voluntary under commercial and operational maintenance practices rather than legally enforceable.
