EPA Section 608 Leak Rate Calculation Sheet

This worksheet is used to calculate the refrigerant leak rate for a comfort cooling appliance and compare it against the applicable threshold. It gives you a place to record the appliance identity, refrigerant type, full charge, refrigerant added over the prior 12 months, and the resulting compliance status. Use it when you need a clear audit trail for a monthly review or after a service event. It is designed to support Section 608 recordkeeping, not to replace a technician's judgment or required regulatory review.

The template is intended for comfort cooling appliances that are subject to Section 608 leak rate calculations. It works best when the appliance has a defined full charge and service records showing refrigerant additions over the last 12 months. If the equipment is not a comfort cooling appliance, or if another rule set governs the unit, this sheet may not be the right fit. Use the appliance type field to keep scope clear before you calculate.

Complete it whenever you perform the monthly leak rate review, and again after any service event that changes the refrigerant added over the prior 12 months. Many teams also use it during scheduled compliance checks so the calculation, threshold comparison, and next steps stay current. If the leak rate exceeds the threshold, update the sheet immediately after corrective action and keep the supporting documents attached. The key is to maintain a current record rather than reconstructing the calculation later.

A technician, facilities manager, or compliance coordinator who has access to the appliance records and service history should prepare the calculation. The attestation should be completed by the person responsible for the review, with a title that makes their role clear. If your process requires a second review, use the supporting documents and notes sections to show who verified the result. Keep the prepared_by field specific so the audit trail is easy to follow.

Use the appliance's full charge, the amount of refrigerant added during the prior 12 months, and the applicable threshold percent for that appliance. The refrigerant type should match the service record, and the calculation date should reflect when the review was performed. Avoid free-text estimates where a numeric field is available, and do not leave the threshold ambiguous. If the data is incomplete, note the gap in the corrective action or supporting documents section rather than guessing.

Mark the threshold_exceeded field and set the compliance status according to your internal process. Then document the corrective action taken, such as repair, follow-up inspection, or scheduling additional service, and list the next steps clearly. Attach or reference the service ticket, inspection notes, or other supporting documents so the calculation can be traced. The template is built to help you move from detection to action without losing the record.

Yes. You can add fields for asset tags, service vendor, work order number, or location hierarchy if those details are part of your workflow. If your team uses conditional logic, you can show extra corrective-action fields only when the threshold is exceeded. Keep the form lean by collecting only the fields you actually use, which supports data minimization and makes the worksheet easier to complete accurately.

Ad hoc notes often miss one of the key inputs, such as the full charge or the 12-month refrigerant added amount, which makes the calculation hard to verify later. This template standardizes the fields, the result, and the attestation so the record is easier to review and audit. It also gives you a consistent place for supporting documents and next steps, which reduces back-and-forth when a unit needs follow-up. Use it when you want a repeatable compliance record instead of a one-off calculation.
