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?
