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 C — Legally, the leaks are not required to be repaired, but morally it is advisable to repair the leaks.

EPA leak repair regulations under Section 608 apply mandatory leak repair and verification thresholds strictly to commercial and industrial refrigeration appliances containing 50 pounds or more of refrigerant. Small hermetically sealed appliances are exempt from mandatory repair requirements.
