# 2015
- 2019 Proposed HCFC



# Allocation Rule US EPA, Office of Atmospheric Programs GreenChill Partner Roundtable February 27, 2014

# Today’s Presentation

• Background on the HCFC Phaseout

• How EPA Developed the Proposed Options

• Proposed HCFC
- 22 Approaches and 

## Consumption Allocation Amounts

• Other Proposals in the Rule

# Why phase out HCFCs?

• HCFCs deplete the 

### stratospheric ozone layer

• Ozone layer shields Earth 

### from ultraviolet radiation:

— Skin cancer

— Cataracts

— Weakened immune systems

— Damage to plant life, aquatic ecosystems

## How EPA Implements the HCFC Phaseout

• EPA must ensure compliance with the Montreal Protocol & Clean Air Act Title VI

– Phase out of all ozone
- depleting substances


## • Goal: smoothly transition away from HCFCs

– Focus on HCFC
- 22, it’s 90+% of HCFC use


## • EPA writes rules that issue allowances for import and production of virgin HCFCs

– Allowances decrease over time



### – No HCFC
- 22 allowances in 2020 or beyond

– Complete ban on production and import in 2030

# HCFC
- 22 phaseout timeline

• Jan. 1, 2010 : HCFC
- 22 may only be produced or imported for use in servicing and maintaining pre
2010 systems

• Jan. 1, 2015 : Allowed production/import will be at 

### least 45% below 2010 level, as required by the Montreal Protocol

• Jan. 1, 2020 : No production or import of HCFC
- 22

— Used, recovered and recycled material can still be used

— Virgin material imported or produced before Jan. 1, 2020 can still be used until 2030

# 2015 – 2019 Proposed Rule

• The 2015
- 2019 Proposed Rule has three 

## approaches for setting the amount of HCFC
- 22 consumption allowances each year

– 5
- year Linear Drawdown

– 3
- year Linear Drawdown

– Estimation Approach

# Factors Considered

• Montreal Protocol Cap


## • Clean Air Act requirements & use restrictions
• Servicing need for HCFC
- 22 equipment

– 46,000 MT modeled in 2015 (~100 million pounds)

– Modeled need is based on publicly vetted parameters (installed equipment base, leak rate, charge size, etc.)


## • Market conditions

– Existing HCFC
- 22 supply, uptake of alternatives, transition timelines, feasibility of retrofits for various 

### end uses- 5,000 10,000 15,000 20,000 25,000

2014 2015 2016 2017 2018 2019 2020 HCFC - 22 Allowances (MT) Comparison of EPA's Three Proposed Approaches for HCFC - 22 Estimation Approach (Maxmimum

Amount) 5
- year Linear Drawdown
- Preferred 3
- year Linear Drawdown

These 3 approaches are shown in Table 1 of the Proposed Rule-

5,000 10,000 15,000 20,000 25,000

2014 2015 2016 2017 2018 2019 2020 MT HCFC - 22 Consumption 5 - year Linear Drawdown Approach –

3 Allocation Options

# Also in the Proposed Rule ...
• HCFC
- 22 Production

– Maximum allowed under Protocol (~28,000 MT)

– Or, same as consumption


### • Preferred Approaches for other HCFCs

– HCFC
- 123: 2,000 MT
• Maximum allowed under Clean Air Act section 605



### – HCFC
- 124: 200 MT



### – HCFC
- 142b: 35 MT, decreasing by 5 MT each year


### • No HCFC
- 225ca/ cb allowances

– Narrow de minimus exemption to allow continued use of existing inventory by owner of the inventory
