What must the equipment owners/operators include in recovered refrigerant records for equipment with refrigerant charges that range from 5 to 50 pounds?

For equipment with refrigerant charges ranging from 5 to 50 pounds, the records must specifically include details about the quantity of refrigerant (by type) added or recovered from disposed appliances each calendar month, along with the quantity of refrigerant sent for reclamation or destruction. This requirement is critical for tracking the movement of refrigerants to ensure compliance with regulations aimed at preventing environmental harm due to refrigerant emissions.

The monthly record-keeping is essential because it allows for continuous monitoring of refrigerant usage and disposal, helping to identify potential leaks or excessive usage in a timely manner. It ensures that entities can report accurately about their refrigerant management practices, which can be crucial for compliance with EPA regulations, as well as for maintaining a more sustainable approach to refrigerant management.

The other choices focus on broader or less precise reporting intervals, such as yearly or seasonal variance, which do not meet the regulatory requirements for timely accounting that are necessary in this context. The monthly detail offers a clearer picture of refrigerant handling, which is vital for both regulatory compliance and environmental protection.
