Major Recordkeeping Requirements for Stationary Refrigeration

Primary tasks

EPA regulations (40 CFR Part 82, Subpart F) under Section 608 of the Clean Air Act include recordkeeping requirements that are specific to different persons or companies involved with stationary refrigeration and air-conditioning equipment. This page provides a brief overview of these requirements.


Technicians must keep a copy of their proof of certification at their place of business.

Technicians servicing appliances that contain 50 or more pounds of ozone-depleting refrigerant must provide the owner with an invoice that indicates the amount of refrigerant added to the appliance. Technicians must also provide records of leak inspections and tests performed to verify repairs of leaking appliances that contain 50 or more pounds of ozone-depleting refrigerant.

Technicians disposing of appliances containing between 5 and 50 pounds of refrigerant must keep records of the disposal. These are typically field-installed appliances such as residential AC split systems. This requirement applies to appliances containing ozone-depleting and substitute refrigerant, such as HFCs. The records primarily include: location and date of recovery, type of refrigerant recovered, monthly totals of the amounts recovered, and amounts sent for reclamation.

Owners or operators must submit a report to EPA for any appliance containing 50 or more pounds of ozone-depleting refrigerant that leaks 125 percent or more of the full charge in a calendar year. This report must describe efforts to identify leaks and repair the appliance. Reports are due on March 1 for an appliance that leaked more than 125 percent of its full charge in the prior year.
