Kigali Amendment to Montreal Protocol — October 15, 2016
4
• Global agreement on HFC phase-down1
• Ratified by 65+ countries, including E.U. countries, Canada and Mexico2
• Still under consideration by the U.S. government
– Ratification in the U.S. could lead up to 33,000 additional manufacturing jobs and increased global market share3
Entered into effect January 1, 20191 http://conf.montreal-protocol.org/meeting/mop/mop-28/final-report/English/Kigali_Amendment-English.pdf2 https://kigali-amendment.openclimatedata.net3 http://www.alliancepolicy.org/downloads/press-releases/Kigali_Economic_Report.pdf

U.S. EPA Continues to Roll Back Previous Regulations
6
• SNAP Rules 20/21– Rule 21 remains in litigation; EPA currently not enforcing HFC delistings1
• Clean Air Act Section 608– Proposal to exclude HFCs from Section 608 of Refrigerant Management Program (RMP)2
• Would still apply to ozone-depleting substances– Appliances with 50 or more pounds of refrigerant would no longer be subject to:
• Conduct leak rate calculations when refrigerant is added to an appliance• Repair an appliance that leaks above a threshold leak rate• Conduct verification tests on repairs• Conduct periodic leak inspections on appliances that exceed the threshold leak rate• Report to EPA on chronically leaking appliances• Retrofit or retire appliances that are not repaired• Maintain related records
New EPA regulations forthcoming in early 20191https://www.regulations.gov/document?D=EPA-HQ-OAR-2003-0118-16412https://www.epa.gov/section608/revised-section-608-refrigerant-management-regulations
California Leads State Efforts in Reducing HFC Emissions
7
• California adopts SNAP Rules 20 and 21 into state law– Effective Jan. 1, 2019
– Manufacturers cannot sell equipment or products which use prohibited HFCs that are manufactured after their respective prohibition dates and must provide a written disclosure to the buyer as part of the sales transaction and invoice
– Allows CARB to list or delist refrigerants, regardless of status, at a federal level
• New York, New Jersey, Maryland, Connecticut, Washington and Vermont have also announced plans to adopt SNAP Rules 20 and 21.
Industry favors consistent approach across all stateshttps://leginfo.legislature.ca.gov/faces/billStatusClient.xhtml?bill_id=201720180SB1013
U.S. Climate Alliance Membership Increasing
8
• States committed to leading on climate change initiatives, including reduction of HFCs
• 21 members and growing– Wisconsin, Michigan, Illinois
and New Mexico have joined this year
Now make up 49 percent of population and more than 50 percent of GDPhttps://www.usclimatealliance.org/publications/2019/2/12/wisconsin-governor-tony-evers-joins-us-climate-alliance
Pending CARB Rulemaking: SLCP Proposals to Reduce HFCs to Fill Gap
9
AC will begin first; board meeting and final regulation scheduled for December – GWP<750: Stationary air conditioning — effective 2023– No additional rulemaking for chillers — will rely on SNAP Rule 21 now in place, per SB 1013
Commercial refrigeration will follow; board meeting and final regulation scheduled for March 2020– GWP<150: Stationary refrigeration >50 lbs — effective 2022
Sales Restrictions on Refrigerants– No production, import, sales, distribution or entry into commerce of refrigerants with
GWP≥1,500 effective in 2022– Open to use of reclaim for service, proposed sales exemption for R-410A
AC stakeholder meeting scheduled for March 6https://ww2.arb.ca.gov/resources/documents/workshop-hydrofluorocarbon-emission-reduction-measureshttps://ww2.arb.ca.gov/resources/documents/stationary-air-conditioning-rulemaking-march-06-2019

ANSI/ASHRAE Flammability Classifications
• Class 2L vs. 2 Flammability Classification Based on:– Burning velocity
• Maximum velocity at which a flame propagates in a normal direction relative to unburned gas ahead of it
• Lower burning velocity <10 cm/s = 2L• Higher burning velocity >10 cm/s = 2 or 3
• Class 2 vs. 3 Flammability Classification Based on:– Heat of combustion and lower flammability limit (LFL)
Many of the lower-GWP refrigerants are classified as A2L.1313
