# SNAP Stakeholder Workshop: Heavy-Duty Motor Vehicle Air Conditioning November 18, 2015

# Welcome and Introductions

2

# Climate Action Plan: 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 ShortLived Climate Pollutants to promote climate - friendly alternatives to highGWP 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

# Scope of Meeting  

## Background  

### Significant New Alternatives Policy (SNAP) Program  

### Overview of Recent Actions & Future Considerations  

## Climate - friendly Alternatives for Heavy - Duty Motor Vehicle Air Condition Systems  

## Discussion

2• Acceptable - those that reduce overall risk to human health & environment • Acceptable with use restrictions - if needed to ensure safe use • Unacceptable 

## Evaluates alternatives & lists alternatives as:

• Aerosols; Foams; Refrigeration and A/C; Solvents; Fire Suppression; Adhesives, Coatings, Inks, etc. 

## Sectors include:

• Ozone Depletion Potential • Global Warming Potential • Flammability • Toxicity 

## Considers: • Local Air Quality • Ecosystem Effects • Occupational & Consumer Health/Safety 5

# SNAP Actions 2014-2015  

## Issued two acceptability notices adding alternatives  

## 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 Reductions: 54 - 64 MMTCO2eq in 2025 Near term changes can provide both near and long term benefits

# Change of Status Rule: MVAC Refrigerants July 2015 Change of Status Rule  

### HFC - 134a unacceptable  

### As of MY 2021  

### New, light- duty vehicles only  

### Narrowed use limits finalized for export vehicles  

### Available through MY 2025  

### Limited to vehicles exported to countries lacking infrastructure for servicing alternative refrigerants  

### Several HFC and HCFC refrigerant blends unacceptable  

### As of MY 2017  

### New, light- duty vehicles only 8

# September 11 Stakeholder Meeting  

## EPA considering proposed rule that could include :  

## Listing acceptable alternatives with use conditions  MVAC: HFO - 1234yf acceptable for limited heavy-duty (HD) vehicle types  Other refrigeration & air conditioning end - uses for flammable and highly 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 20th final rule  End - uses based on stakeholder comments, EPA analysis  Refrigeration and A/C  Rigid PU spray foam  Fire suppression 9

# Climate-Friendly Alternatives for HD MVAC Systems

10  

### CO 2 

### (R - 744) and HFC - 152a are listed as acceptable, subject to use conditions, in all new MVAC systems, including HD  

### HFO - 1234yf listed as acceptable, subject to use conditions, in newly manufactured passenger vehicles and light- duty trucks in 2011  

### EPA is considering to propose listing HFO - 1234yf acceptable, subject to use conditions, for limited HD vehicle types e.g.,:  Medium - duty passenger vehicles  HD pickup trucks  Complete HD vans  

### Seeking stakeholder input

# MVAC Applications & Terminology MVAC Includes:  

### Light- duty vehicles  

### HD vehicles  

### Off -road vehicles  

### Buses  

### Passenger Rail 

## Terminology used by Heavy- Duty Greenhouse Gas Program  

### HD pick- up trucks and vans  

### Vocational vehicles and trucks  

### Commercial medium and heavy - duty on -highway vehicles (i.e., trailertrucks; combination tractors) 10

# HD Vehicle Classifications by Gross V ehicle Weight Rating (GVWR) Class 2b 3 4 5 6 7 8 GVWR (lb) 8,501 - 10,000 10,001 - 14,000 14,001 - 16,000 16,001 - 19,500 19,501 - 26,000 26,001 - 33,000 > 33,000

# Open Dialogue – Questions and Answers

# Discussion Questions

14  

### EPA reviews substitutes on an end - use by end - use basis (or by application within an end - use). EPA believes it has sufficient information at this time to move forward with a proposed SNAP listing for HFO - 1234yf for certain but not all heavy- duty (HD) vehicle types. Recognizing that a proposed rule that included a listing decision for all vehicle types would take additional time, should EPA move forward more narrowly today?  

## What barriers do companies face for a transition to lower - GWP alternatives in HD and off -road vehicles?  

### Which vehicle types might be early adopters?  

### Which vehicle types, if any, might face technical barriers to transition?  

### And, what benefits could be expected from making a transition?15  

### In what situations and how often are the OEM - installed MVAC systems altered by secondary or tertiary manufacturers for HD vans? Vocational vehicles? Tractor- trailers?

 Are MVAC systems in these vehicles altered in the aftermarket?  What types of alterations would be made? Would they affect the amount of refrigerant or the likelihood of refrigerant leaks?  

### EPA's understanding is that the MVAC systems for medium - duty passenger vans, HD pickup trucks, and complete HD vans are substantially the same as those for light- duty (LD) vehicles. Do other HD vehicle types also have MVAC system configurations similar to those used in LD vehicles?  

### How can SNAP continue to help “encourage private - sector investment in low - emissions technology?”
