Your Guide to Federal and State HFC Regulations in North America for HVACR Refrigerants

HFC Regulations Fact SheetInternational“Perhaps the single

Montreal Protocol (1987)

most successful• Phaseout of ozone depleting substances (ODS), leading a shift to hydrofluorocarbons (HFCs)

international agreement• New production and import of virgin HCFC-22 will be phased out in North America by 2020

to date has been theKigali Amendment (2016) to the Montreal Protocol

Montreal Protocol.”• Phasedown of production and consumption of HFCs to reduce greenhouse gas emissions

Kofi Annan,• Effective in January 2019 where ratified

UN Secretary-General,1997-2006• More than 90 countries have ratified (including Canada and excluding U.S., as of February 2020)• Driving global transition to lower global warming potential (GWP) solutions. Learn more at Opteon.com

U.S. Federal
Significant New Alternative Policy (SNAP)• The Environmental Protection Agency (EPA) made certain HFCs unacceptable for use in SNAP Rules 20 (2016) and 21 (2017).
• However, SNAP Rules 20 and 21 were partially vacated by the D.C. Circuit Court; the EPA is reviewing the court decision. The industry awaits the EPA rewrite,
expected in 2021.

• Despite being vacated at the federal level, states may choose to adopt and set their own timeline for the implementation of rules. The following table shows anabbreviated view, highlighting some of the key restrictions. For further details, visit EPA.gov/SNAP.

12Refrigerant Management (Clean Air Act, Section 608)••••

In 2016, the EPA extended the refrigerant management program to include HFCs ( 40 CFR Part 82, Subpart F, under Section 608 of the Clean Air Act).
The EPA signed a rule in February 2020 that rescinded some parts of the program, including the extension of leak repair provisions to appliances using HFCs.
This rule did not rescind other parts affecting HFCs, such as sales restriction or requirements for technician certification, for safe disposal, recovery, and reclamation.
Likewise, this rule does not affect the requirements for equipment containing ozone depleting substances. For more information, visit EPA.gov/Section608.

U.S. Federal
American Innovation and Manufacturing (AIM) Act• On December 27th, 2020, the AIM Act was signed into law, allowing for a federal phasedown of the production and consumption of HFCs, with implementation
dates yet to be developed by the EPA• The phasedown will be managed through an allocation program, and the schedule will mirror the schedule proposed in the Kigali amendment• This legislation grants the EPA the authority to establish standards for recovery and reclamation of HFCs
• The Aim Act authorizes the EPA to facilitate transitions to next-generation technologies by establishing sector-based use case restrictions• Implementation could create significant economic and new employment benefits

U.S. State-Level Activity

WAMTThe United States Climate Alliance, founded in 2017, is abipartisan coalition of U.S. states and territories committed toreducing greenhouse gas emissions by at least 26-28% below
2005 levels by 2025—this is consistent with the goals of the2015 Paris Agreement. The Alliance represents greater than
55% of the U.S. population and over 60% of the economy. Asof February 2020, there are 25 members, with 8 states joining
in 2019. Visit USClimateAlliance.org for more information.
