Climat imate Act ction Pl ion Plan: an: HFC HFCs  Continue international diplomacy  Lead negotiations under the Montreal Protocol to phase down HFCs  Global phase down could reduce over 90 gigatons of CO2eq by 2050, equal to roughly two years worth of current global GHG emissions  Work with partners in the Climate and Clean Air Coalition to Reduce Short- Lived Climate Pollutants to promote climate-friendly alternatives to high- GWP HFCs, address technical standards, and reduce emissions from HFC use  Address HFCs through domestic actions  Use existing Clean Air Act authority of Significant New Alternatives Policy (SNAP) Program to approve climate-friendly chemicals, prohibit some uses of most harmful Provide federal leadership by purchasing cleaner • alternatives to HFCs whenever feasible and by transitioning to equipment using safe, more sustainable alternatives 3

Scop ope of Me of Meeti ting  Background  Significant New Alternatives Policy (SNAP) Program  Overview of Recent Actions & Future Considerations  Alternatives for Fire Protection Sector  Discussion 2

Evaluates alternatives & lists alternatives as: • Acceptable - those that reduce overall risk to human health & environment • Acceptable with use restrictions - if needed to ensure safe use • Unacceptable Sectors include: • Aerosols; Foams; Refrigeration and A/C; Solvents; Fire Suppression; Adhesives, Coatings, Inks, etc. Considers: • Local Air Quality • Ozone-Depletion Potential • Ecosystem Effects • Global Warming Potential • Occupational & Consumer • Flammability Health/Safety • Toxicity 5

SNAP NAP A Acti tions ns 201 014-2015  Issued two acceptability notices adding alternatives Near term changes can provide both near and long term benefits  Issued new rule adding five low-GWP flammable refrigerants with use conditions  Published Status Change Rule prohibiting certain HFCs in certain end-uses  HFC Emissions Avoided: 54- 64 MMTCO2eq in 2025 6

Some me Key Pr Principl ples Guid s Guidin ing O g Our ur Thinki king  SNAP rules will continue to consider individual end-uses  No across the board GWP cut offs  No prohibition on HFCs as a whole, or in any one sector  New HFCs or HFC blends may be listed if risk not greater than other available substitutes  Recognition that timing is a critical dimension and that each end use has unique considerations  Status change actions will be issued through notice and comment rulemaking 8

Sep eptember ember 1 11 Stakehold older M r Meeting ng  EPA considering proposed rule that could include :  Listing acceptable alternatives with use conditions  Refrigeration & air conditioning end-uses for flammable refrigerants; Fire suppression: e.g., streaming agent for aviation  Listing of unacceptable alternatives  Certain HC and HC blends for stationary AC retrofits and MVAC systems  Change of listing status from acceptable to unacceptable  EPA considering later transition dates than in July 20 th final rule  End-uses based on stakeholder comments, EPA analysis  Refrigeration and A/C  Rigid PU spray foam  Fire suppression: e.g., PFCs, SF6, HFC-23 9

Ne Next xt S Steps eps  Continue to expand SNAP acceptable list  Continue to work with stakeholders  E.g., Food Cold Chain Workshop in Montreal (held November 21st)  Sector workshops and Stakeholder meetings  Develop next SNAP Notice for acceptable listings  Develop next SNAP Rule to include alternatives that are:  Acceptable with use conditions  Unacceptable  Change of status 10

 EPA considering a proposed rule that may consider:  Listing of 2-BTP as acceptable in certain applications  Change of listing status from acceptable to unacceptable for:  PFCs (C 3 F 8 and C 4 F 10 ) in fire suppression total flooding uses  PFC (C 6 F 14 ) in fire suppression streaming uses  Request for comments and updated information on total flooding uses of SF 6 and HFC-23  Comments on July SNAP final rule, recent petitions suggested EPA also consider fire suppression applications  Seeking stakeholder input pre-proposal given interest in applications 15

Open pen D Dialogue e – Questi uestions a ns and d An Answ swer ers

Disc scussi ssion Q n Questi uestions ns  What specific end-uses and applications need additional low-GWP alternatives?  Are additional submissions anticipated for fire protection applications (e.g., new chemicals, new blends, existing chemicals for new applications, new processes or technologies)?  Under SNAP , a potential substitute is often submitted for review for more than one use in a particular sector. EPA reviews substitutes on an end-use by end-use (or end-use category) basis. Is it helpful for EPA to move forward with listings in particular end-uses where we have made a determination recognizing we may still be reviewing other end-uses? 17
