HFC Phase-Down Amendment to Montreal Protocol Closer to Reality
On 11/5/15, the 27th Meeting of the Parties to the Montreal Protocol in
Dubai, UAE, concluded with all countries agreeing to work on a 2016
amendment to phase-down HFCs*.

SNAP: Additional Change of Status for Refrigerants Is Coming
EPA Proposal to Amend Clean Air Act Section 608 Ref. Mgmnt. Regs (11/9/15)
Lowers repair leak rate threshold for 50+ lbs. refrigerant charge systems
– From 35% to 20% for industrial process refrigeration (IPR) and comm. ref. equipment
– From 15% to 10% for comfort cooling equipment
Requires regular leak inspections or continuous monitoring devices
for ref/AC systems:
– Annual inspections for systems normally containing 50+ lbs. of refrigerant
– Quarterly inspections for commercial refrigeration and IPR systems normally containing
500+ lbs. of refrigerant
Prohibits operation of systems with 50+ lbs. of refrigerant that have
leaked 75% or more of full charge for two consecutive years
Requires techs to keep a record of refrigerant recovered during system
disposal from systems with a charge size from 5–50 pounds
Extends the requirements of the refrigerant management program to
cover substitute refrigerants, such as HFCs

Other Refrigerant-Related Activities Are Underway
Canada proposed notice of intent to control the manufacture,
import and use of certain HFCs in consumer aerosols, foam
blowing, commercial refrigeration and MVAC
California has proposed HFC use regulations as well
Safety standards and building codes are under revision
– U.S.: UL 1995, ASHRAE 15
– International: ISO 5149, IEC 60335, EN378
AHRI A2L Flammability Research Study in Progress
AHRI’s Second Alternative Refrigerants Evaluation Program
has concluded with focus on high ambient operation for AC
2015 Was Warmest Year Since 1880, per USA Today Article, 1/20/16
COP21 Meeting in Paris, 12/12/2015
Nations agreed to limit global temperature increase to 2 °C
Countries to update pollution reduction pledges by 2020
This means reducing
emissions by 40–70% by
2050 compared to 2010!
Can we continue to invent, innovate and develop new products while
maintaining existing systems with a “business as usual” approach?
