11.3 Compliance Checklist and Best Practices

Compliance Is a System, Not a Single Rule

Everything in the previous chapters — venting prohibition, certification, recovery levels, leak repair, disposal — comes together as one compliance program. EPA enforces it through inspections and audits, and violations carry civil penalties of up to $44,539 per day, per violation under current penalty figures. The good news for the exam and the field: compliance is mostly about documentation and discipline. If you can prove what you did, you are usually defensible. This section is your practical checklist.

The Daily Technician Compliance Checklist

Follow this numbered routine on every job:

1. Verify your certification covers the equipment. Type I (small appliances), Type II (high-pressure), Type III (low-pressure), or Universal. Keep proof of certification at your place of business.
2. Identify the refrigerant from the nameplate or with an electronic identifier before opening anything.
3. Confirm your recovery/recycling equipment is EPA-certified (required for equipment made after Nov 15, 1993) and in good working order.
4. Recover before opening — never vent any regulated refrigerant.
5. Use nitrogen with a regulator for pressure testing — never oxygen or compressed air.
6. Recover to the required evacuation level for the system type and charge size, then verify it.
7. Document the refrigerant added or removed (type, amount, date).
8. Charge zeotropic blends as liquid, and never mix refrigerant types.
9. Label and store cylinders correctly (gray/yellow recovery cylinders, current test date, under 80% fill).
10. Retain all records for 3 years.

The Sales Restriction (and Why It Matters)

EPA restricts who can buy regulated refrigerant. Refrigerant in containers larger than 2 lbs may be sold only to EPA-certified Section 608 (or 609) technicians, certified reclaimers, or distributors who certify they will resell only to certified buyers. Self-sealing small cans (2 lbs or less) of certain refrigerants are also sales-restricted to certified technicians under the 2016 rule. This restriction is the front end of the compliance chain — it is why your wholesaler asks for your certification number, and it is a record the seller must keep for 3 years.

Recordkeeping: Who Keeps What, and for How Long

The number to memorize is 3 years — it is the universal retention period. The party that must keep the record changes with the document type.

The 50-lb Owner/Operator Threshold

Owners or operators of appliances containing 50 or more pounds of refrigerant carry the heaviest recordkeeping load. They must:

• Keep servicing records documenting the date, type of service, and quantity of refrigerant added.
• Maintain leak inspection and repair-verification records.
• Report to EPA any such appliance that leaks 125% or more of its full charge in a calendar year.

Technicians servicing those 50-lb-plus appliances must hand the owner an invoice showing the amount of refrigerant added so the owner can meet these duties.

What an EPA Audit Actually Checks

When an inspector arrives — or requests documents — they typically look for:

1. Technician certifications on file for everyone handling refrigerant.
2. Recovery/recycling equipment certification (the manufacturer's EPA certification for post-1993 equipment).
3. Recovery and recordkeeping logs — what was recovered, when, and how it was reconciled.
4. Leak-rate calculations and repair documentation for systems over the size thresholds, including follow-up verification tests.
5. Chronic-leak reports for any appliance that hit the 125% trigger.
6. Sales records proving refrigerant was sold only to certified buyers.
7. Disposal verification statements for equipment received empty.

Worked Example: A facility owns a 600-lb R-123 chiller. In one calendar year it adds 780 lbs of make-up refrigerant chasing a leak. Is anything triggered?

• Leak amount as % of charge: 780 / 600 = 130% of full charge in the calendar year.
• Because 130% exceeds the 125% chronic-leak threshold, the owner must report this appliance to EPA.
• The owner must also keep the service records and leak-repair documentation (it is a ≥ 50-lb appliance) for 3 years, and the technician must verify the repair and provide invoices showing refrigerant added.

Don't Confuse These (Common Exam Mistakes)

• Phaseout vs. phasedown: CFCs/HCFCs are phased OUT (eliminated); HFCs are phased DOWN (reduced under the AIM Act, not eliminated).
• Certification never expires, but you still must keep proof on hand.
• Recycled vs. reclaimed: recycled refrigerant stays with the same owner; reclaimed refrigerant is cleaned to AHRI 700 purity by a certified reclaimer and may be resold.
• 80% vs. 90% recovery efficiency for small-appliance recovery equipment (system-dependent vs. self-contained), versus the 80% fill limit for cylinders — different 80s.

For the Exam: 3 years is the universal retention period. The 50-lb charge triggers owner recordkeeping; 125% of charge lost in a calendar year triggers an EPA chronic-leak report. Refrigerant in containers over 2 lbs is sold only to certified buyers. An audit checks certifications, equipment certification, recovery logs, leak/repair records, sales records, and disposal verification statements.
