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.

EPA leak repair rules mandate action thresholds based on commercial and industrial leak rates, exempting small hermetically sealed appliances like water coolers from mandatory federal repair requirements, though proactive maintenance remains best marine practice.
