If a chiller containing 150 pounds of HCFC refrigerant is leaking above the threshold, what must be done within 30 days?

When a chiller containing 150 pounds of HCFC refrigerant is leaking above the regulatory threshold, it is essential to repair the appliance and conduct an initial verification test within 30 days to ensure compliance with EPA regulations. This requirement is in place to minimize the release of refrigerants into the environment, which can contribute to ozone depletion and global warming.

Conducting a repair entails addressing the source of the leak, and the follow-up verification test is crucial to confirm that the repair has been effective and that the refrigerant levels are now managed according to legal standards. Failure to address leaks promptly not only violates environmental regulations but can also lead to more extensive and costly repairs if the situation worsens.

In contrast, replacing the entire chiller would not be necessary if the leak can be effectively repaired. Reducing the refrigerant charge might temporarily bring levels below the threshold, but it does not address the underlying issue of the leak. Ignoring the leakage until the next service contradicts the responsibility of maintaining environmental standards and could expose the operator to significant fines or penalties. Hence, repairing the appliance and confirming the repair through testing is the most appropriate and compliant action to take.
