LeakGuard 84 — EPA AIM Act & Section 608 Statutory Calculation Record

Statutory calculation record. Not an official agency endorsement; certified technician verification required for physical repairs.

No Current Calculation Available

There is no current calculation record available to print. Either no calculation has been performed yet, or inputs were modified after the previous calculation. Return to the calculator and select “Calculate leak rate” to produce a valid record.

Step 1 of 4: Appliance

Use the equipment nameplate and service records.

View regulatory thresholds & statutory rules (EPA AIM Act & CARB RMP)

Federal leak-repair calculations under 40 CFR Part 84 generally apply, from January 1, 2026, to appliances charged with 15 lbs or more of covered HFC refrigerants (commercial refrigeration 20%, industrial process 30%, comfort cooling 10%). Residential and light-commercial AC/heat pumps are excluded. R-22 systems are assessed under Section 608 rules (50 lb threshold). Selecting California adds California CARB RMP requirements (14-day repair clock). The engine computes your statutory applicability and deadlines from your inputs.

Equipment type Statutory category per 40 CFR § 84.106 / § 82.156; it sets the leak-rate trigger.

Appliance subsector Charge size alone cannot establish applicability; confirm from equipment documentation.

Refrigerant From the equipment nameplate. Low-GWP refrigerants are outside the federal leak-repair trigger.

Full charge of this circuit (lbs) Nameplate charge per independent circuit. Part 84 calculations generally start at 15 lbs for covered equipment.

Facility jurisdiction California facilities can owe both federal (30-day baseline) and state CARB RMP (14-day) duties; the result lists them separately.

Step 2 of 4: Facility and service event

Enter the refrigerant addition exactly as recorded. Additions caused by anything other than leakage (for example, commissioning, retrofits, or pumped-out charge) are not ordinary leak additions and need separate assessment — this tool does not cover those cases.

Facility name (optional — defaults to "My Facility")

Appliance ID / asset tag (optional — defaults to "Appliance 1")

Service date (refrigerant added) (defaults to today)

Pounds added this event (lbs) Combine all same-day additions into one total.

Days since the previous addition Whole days between this addition and the prior one (1–3650).

Calculation method Use the method already established for this appliance. This prototype does not authorize switching methods.

Prior additions (past 365 days and current calendar year) Add any service events where refrigerant was added to this circuit in the past 365 days. Exclude today's addition.

No prior additions recorded. If there were no prior additions in the past 365 days, leave this empty.

Is this service history complete? Yes — I supplied every addition for the rolling 365-day window and current calendar year (including “none” if empty). No — some additions may be missing (the result will be marked “review required”).

Prior calendar year history Used only for the chronic-leaker reporting check.

This is the first leak-rate calculation for this appliance under Part 84 (after January 1, 2026) The engine then applies the transitional calculation basis.

Ongoing repair or verification events (optional)

Original triggering addition date If an earlier addition already started the repair clock.

Last verified repair (rolling reset) Last successful follow-up test that repaired all identified leaks.

Successful initial verification date

Returned to normal operation Only after a repair that required evacuation.

The repair required evacuation of the appliance

Repair requires an industrial process shutdown (120-day federal window)

Where both jurisdictions apply, the earliest applicable date governs. These are baseline deadlines calculated from the dates you supplied; exceptions, extensions, and suspended clocks are outside this prototype’s scope. “Not determined” means a required event date is missing — not that no duty exists.

Estimated refrigerant costs and assumptions

Est. cost of this event

Est. annual refrigerant cost

Cost and emissions figures are rough estimates: they assume the average refrigerant prices and global-warming potentials embedded in the engine and that the current leak rate continues unchanged for 365 days. Actual market prices and leak behavior vary.

Chronic-leaker (calendar-year) evaluation

Under 40 CFR § 84.106 / § 82.156, appliances that leak 125% or more of their full charge in a calendar year require an annual report to the EPA Administrator by March 1 of the following year. Current and prior calendar years are evaluated independently below.

Technical record metadata (integrity digest, IDs)

—

The SHA-256 digest is an integrity check: it detects changes to the record when compared against a separately kept original. It is not a signature, does not authenticate an issuer, and does not prove compliance.

EPA AIM Act & Section 608 Calculation Record. Calculation support only; not a certification of compliance.

LeakGuard 84 is a statutory calculation and recordkeeping tool. Calculations are evaluated under 40 CFR Part 84 Subpart C, Clean Air Act Section 608, and California CARB RMP (17 CCR § 95380 et seq.). A calculation record does not replace on-site certified technician leak inspections or physical repair verification. Payment processing is handled securely by Stripe; email dispatch is transmitted via encrypted mail relay; conversion analytics are processed via Meta Pixel/Conversions API. We store your calculation for recovery and delivery. With your optional analytics consent, Meta receives usage events, not facility details or calculation results. See our privacy notice.
