CThe leaks must be repaired within 30 days.
DThe leaks must be repaired if the annual leak rate exceeds 35% of the total charge.
AI Explanation

The correct answer is A) Legally, the leaks are not required to be repaired, but morally it is advisable to repair the leaks. The EPA Clean Air Act regulations do not require the repair of refrigerant leaks in small hermetically sealed shipboard water coolers with a 20-ounce charge weight. These types of small, self-contained systems are exempt from the leak repair requirements. However, while not legally mandated, it is still generally advisable to repair any refrigerant leaks to prevent environmental and operational impacts. The other answer choices are incorrect because B) the 15% annual leak rate threshold only applies to larger refrigeration systems, C) there is no 30-day repair requirement for this type of system, and D) the 35% annual leak rate does not apply to this small, hermetically sealed system.
