Leak Detection and Repair Procedures Flashcards

An owner decides not to repair a leaking appliance that exceeds the threshold. How soon must a retrofit or retirement plan be developed?

Answer: Within 30 days

If leaks will not be repaired, a retrofit or retirement plan must be developed within 30 days.

Once a retrofit or retirement plan is developed, generally how long does the owner have to complete the retrofit or retirement?

Answer: 1 year

Retrofits or retirements generally must be completed within one year of the plan's development.

An appliance with 50 or more pounds of refrigerant leaks 125% or more of its full charge in a calendar year. What must the owner do?

Answer: Submit a report to EPA explaining efforts to identify and repair the leaks

Chronically leaking appliances (125% or more of full charge per year) require a report to EPA by March 1 of the following year.

How long must leak inspection and repair records for appliances subject to the leak repair rules be kept?

Answer: 3 years

EPA requires owners and technicians to keep these records for at least three years.

A commercial refrigeration system with 600 pounds of refrigerant has exceeded its leak threshold. How often must leak inspections be conducted until it shows no leaks above threshold for four consecutive quarters?

Answer: Quarterly

Commercial refrigeration and IPR systems of 500 pounds or more need quarterly inspections until four consecutive quarters are below the threshold.

How does 'mothballing' an appliance affect the 30-day leak repair deadline?

Answer: The repair clock is suspended until the appliance is brought back online

Evacuating and mothballing an appliance pauses the repair deadline until the system is returned to service.

Each time refrigerant is added to an appliance covered by the leak repair rules, what must be done?

Answer: Calculate the leak rate

A leak rate calculation is required at every refrigerant addition to see whether the threshold has been exceeded.
