Who has to report
- 40 CFR 84.106(j): HFC appliances with 15 lb or more that leak 125% or more of their full charge in a calendar year. Reports go through EPA's electronic reporting platform.
- 40 CFR 82.157(j): CFC and HCFC appliances with 50 lb or more, same 125% test. Reports go to 608reports@epa.gov.
How to check
pounds added in the calendar year (excluding seasonal variance, retrofit and installation charges) / full charge x 100 >= 125%
Example: a 40 lb rack circuit that received 20 lb in March, 18 lb in July and 14 lb in November has 52 lb in the year, 130% of its full charge. It is a chronic leaker and must be reported by March 1 of the next year.
What goes in the report
The required contents are listed in 84.106(m) (and 82.157(m) for Section 608). Before you file, gather the appliance identification and location, the refrigerant and full charge, the leak rate history for the year, the leaks found and the repairs attempted. Keep a copy of the report and any EPA response with your records.
LeakLedger adds up counted additions per calendar year for every appliance and shows the March 1 deadline on the dashboard as soon as an appliance crosses 125%.
