The EPA's Updated Refrigerant Management
What Technicians Need to Know
What are the Section 608 regulations?
Section 608 of the Clean Air Act prohibits the knowing release of refrigerant during the maintenance, service,
repair, or disposal of air-conditioning (AC) and refrigeration equipment. The EPA requires proper refrigerant
management practices by technicians, owners and operators of refrigeration and AC systems, and others.
What's changing in these regulations?
In the fall of 2016, the EPA updated the existing requirements related to ozon
depleting substances (ODS), such as CFCs and HCFCs, and extended them to
substitutes such as HFCs,1 The updates include:
•	More stringent requirements for repairing leaks in larger appliances;
•	New recordkeeping for the disposal of appliances containing five to 50
pounds of refrigerant;
•	New reporting requirement that kicks in when larger appliances leak
125% or more of their charge in a calendar year;
•	Restricting the sale of HFC refrigerant to technicians certified under
Sections 608 or 609 of the Clean Air Act; and
•	Changes to improve readability and simplify compliance.
How will the new requirements affect technicians?
Technicians must handle HFC refrigerants and appliances containing HFC refrigerants in the same manner that
they now handle ozone-depleting refrigerants. Implementation dates are staggered to provide time for
outreach and training of technicians. Starting as early as January 1, 2017, technicians will need to comply
with revised provisions.2 Changes to the existing regulations are underlined.
Sales Restriction
Starting January 1, 2017, recovered ODS and substitute refrigerant may not be resold unless it has been
reclaimed by a certified reclaimer or is charged into equipment belonging to the same owner.
Starting January 1, 2018, the sale of ODS and substitute refrigerant is restricted to certified technicians.
Technician Certification
Starting January 1, 2018, technicians must:
•	Pass a certification exam offered by an approved technician certification program in order to maintain,
service, repair, or dispose of appliances containing ODS or substitute refrigerants. The certification
exam will be updated to reflect the new rules and new refrigerants prior to this date.
•	Keep a copy of their certificate at their place of business.
•	Maintain a copy of their certificate until three years after no longer operating as a technician.
In addition to protecting
the ozone layer, the
EPA estimates that the
updated requirements
will decrease annual
greenhouse gas
emissions by
7.3 million MTCCtee—
that's equivalent to
taking 1.5 million cars
off the road per year.
1	These regulations do not extend to substitutes that have been exempted from the venting prohibition, such as ammonia.

The EPA is not changing the types of certifications or requiring recertification for currently certified technicians.
To assist in reissuing lost certification cards, certifying organizations must post online lists of newly certified
technicians. Technicians mav opt out of the online lists if thev so choose.
New Recordkeeping for Appliances with 5 to 50 Pounds of Refrigerant
Starting January 1, 2018, technicians who dispose of mid-sized appliances (e.g., residential split systems),
must keep records of:
•	The location, date of recovery, and type of refrigerant recovered for each disposed appliance:
•	The guantitv of refrigerant, bv type, recovered from disposed appliances in each calendar month: and
•	The guantitv of refrigerant, and type, transferred for reclamation or destruction, the person to whom it
was transferred, and the date of the transfer.
Maintenance, Servicing, Repair, and Disposal
Starting January 1, 2018, technicians must:
•	Evacuate ODS or substitute refrigerants before opening or disposing of appliances to the evacuation
levels specified in the regulations using certified recovery and/or recycling equipment.
•	Before opening or disposing of motor vehicle air conditioning (MVAC) or MVAC-like appliances (e.g.,
cars and construction equipment),
o Evacuate ODS or substitute refrigerant from the appliance in accordance with 40 CFR Part 82,
Subpart B; or
o Reduce the system pressure to below 102 mm of mercury vacuum.
Other Important Changes to the Section 608 Leak Repair Regulations for Technicians
The updated Section 608 regulations include new leak inspection and verification test requirements for
owners/operators that will affect technicians starting January 1, 2019:
Leak inspections are required for appliances that have exceeded the applicable leak rate, according to the schedule
below. All visible and accessible components of an appliance must be inspected, using a method or methods that are
appropriate for that appliance.
Full Charge
Frequency of Leak Inspections
> 500
Once every three months until the owner/operator can demonstrate
through leak rate calculations that the leak rate has not exceeded 20%
(commercial refrigeration) or 30% (IPR) for four quarters in a row.
50 to 500
Once per calendar year until the owner/operator can demonstrate through
the leak rate calculations that the leak rate has not exceeded 20%
(commercial refrigeration) or 30% (IPR) for one year.
50 or more
Once per calendar year until the owner/operator can demonstrate through
the leak rate calculations that the leak rate has not exceeded 10% for one
Initial and follow-up verification tests of leak repairs are required for appliances that exceed the applicable leak
rate. The verification tests must demonstrate that leaks were successfully repaired.
•	An initial verification test must be performed before any additional refrigerant is added to the appliance.
•	A follow-up verification test must be performed only after the appliance has returned to normal operating
characteristics and conditions. There is no minimum timeframe.
Technicians are required to provide service invoices and records of the results of leak inspections or verification tests
to owners/operators.
