Appendix A—Summary of Decisions for New 

Acceptable Substitutes 

I. Listing of New Acceptable Substitutes 

This section presents EPA’s most 

recent acceptable listing decisions for 

substitutes in the refrigeration and air 

conditioning; foam blowing; solvent 

cleaning; adhesives, coatings and inks; 

and fire suppression sectors. For copies 

of the full list of substitutes in all of the 

regulated industrial sectors, visit EPA’s 

Ozone Layer Protection Web site at 

http://www.epa.gov/ozone/snap/lists/ 

index.html. 

The sections below discuss each 

substitute listing in detail. Appendix A 

contains a table summarizing today’s 

listing decisions for new substitutes. 

The statements in the ‘‘Further 

Information’’ column in the table 

provide additional information but are 

not legally binding under section 612 of 

the Clean Air Act (CAA). In addition, 

the ‘‘further information’’ may not be a 

comprehensive list of other legal 

obligations you may need to meet when 

using the substitute. Although you are 

not required to follow recommendations 

in the ‘‘further information’’ column of 

the table to use a substitute consistent 

with section 612 of the CAA, EPA 

strongly encourages you to apply the 

information when using these 

substitutes. In many instances, the 

information simply refers to standard 

operating practices in existing industry 

and/or building-code standards. 

However, some of these statements may 

refer to obligations that are enforceable 

or binding under federal or state 

programs other than the SNAP program. 

Many of these statements, if adopted, 

would not require significant changes to 

existing operating practices. 

You can find submissions to EPA for 

the use of the substitutes listed in this 

document and other materials 

supporting the decisions in this action 

in docket EPA–HQ–OAR–2003–0118 at 

http://www.regulations.gov. 

As described in this document and 

elsewhere, including the original SNAP 

rulemaking published in the Federal 

Register at 59 FR 13044 on March 18, 

1994, the SNAP program evaluates 

substitutes within a comparative risk 

framework. The SNAP program 

compares new substitutes both to the 

ozone-depleting substances being 

phased out under the Montreal Protocol 

on Substances that Deplete the Ozone 

Layer and the CAA and to other 

available or potentially available 

alternatives for the same end uses. The 

environmental and health risk factors 

that the SNAP program considers 

include ozone depletion potential, 

flammability, toxicity, occupational and 

consumer health and safety, as well as 

contributions to global warming and 

other environmental factors. 

Environmental and human health 

exposures can vary significantly 

depending on the particular application 

of a substitute—and over time, 

information applicable to a substitute 

can change. This approach does not 

imply fundamental tradeoffs with 

respect to different types of risk, either 

to the environment or to human health. 

EPA recognizes that during the nearly 

two- decade long history of the SNAP 

program, new alternatives and new 

information about alternatives have 

emerged. To the extent possible, EPA 

considers new information and 

improved understanding of the risk 

factors for the environment and human 

health in the context of the available or 

potentially available alternatives for a 

given use. 

A. Refrigeration and Air Conditioning 

1. R–442A (RS–50) 

EPA’s decision: EPA finds R–442A 

acceptable as a substitute for use in 

retrofit equipment in: 

• Ice skating rinks 

• Commercial ice machines 

• Retail food refrigeration (rack 

refrigeration systems only) 

R–442A is a blend by weight of 31.1 

percent hydrofluorocarbon (HFC)-125, 

which is also known as 1,1,1,2,2- 

pentafluoroethane (Chemical Abstracts 

Service Registry Number [CAS Reg. No.] 

354–33–6), 30.0 percent HFC–134a, 

which is also known as 1,1,1,2- 

tetrafluoroethane (CAS Reg. No. 811– 

97–2), 3.0 percent R–152a, which is also 

known as 1,1-difluoroethane (CAS Reg. 

No. 75–37–6)], 5.0 percent HFC–227ea, 

which is also known as 1,1,1,2,3,3,3- 

heptafluoropropane (CAS Reg. No. 431– 

89–0), and 31.1 percent HFC–32, which 

is also known as difluoromethane (CAS 

Reg. No. 75–10–5). You may find the 

submission under Docket item EPA– 

HQ–OAR–2003–0118–0286 at http:// 

www.regulations.gov. 

Environmental information: R–442A 

has no ozone depletion potential (ODP). 

Its components (HFC–134a, HFC–125, 

HFC–227ea, HFC–32 and HFC–152a) 

have 100-year integrated (100-yr) global 

warming potentials (GWPs) of 1430,1

3500, 3220, 675 and 124 respectively. If 

these values are weighted by the mass 

percentage of the components, then R– 

442A has a GWP of about 1890. All 

components of R–442A are exempt from 

the definition of volatile organic 

compounds (VOC) under CAA 

regulations (see 40 CFR 51.100(s)) 

addressing the development of State 

Implementation Plans (SIPs) to attain 

and maintain the national ambient air 

quality standards. The emissions of this 

refrigerant will be limited given it is 

subject to the venting prohibition under 

section 608(c)(2) of the CAA and EPA’s 

implementing regulations codified at 40 

CFR 82.154(a)(1). 

Flammability information: While 

some components are flammable, R– 

442A as formulated and in the worstcase fractionation formulation is not 

flammable. 

Toxicity and exposure data: Potential 

health effects of this substitute include 

drowsiness, incoordination or dizziness. 

The substitute may also irritate the skin 

or eyes or cause frostbite. At sufficiently 

high concentrations, the substitute may 

cause irregular heartbeat. The substitute 

could cause asphyxiation if air is 

displaced by vapors in a confined space. 

These potential health effects are 

common to many refrigerants. 

EPA anticipates that R–442A will be 

used consistent with the 

recommendations specified in the 

Material Safety Data Sheets (MSDSs) for 

the blend and for the individual 

components. For the blend, the 

manufacturer recommends an 

acceptable exposure limit (AEL) of 1000 

ppm on an 8-hour time-weighted 

average (8-hr TWA). For HFC–134a, 

HFC–125, HFC–32 and HFC–152a, the 

American Industrial Hygiene 

Association (AIHA) recommends 

workplace environmental exposure 

limits (WEELs) of 1000 ppm on an 8-hr 

TWA. In addition, the manufacturer of 

HFC–227ea recommends an AEL of 

1000 ppm on an 8-hr TWA. EPA 

anticipates that users will be able to 

meet workplace exposure limits (WEELs 

and manufacturer AELs) and address 

potential health risks by following

2Under EPA’s phaseout regulations, virgin 

HCFC–22, HCFC–142b and blends containing 

HCFC–22 or HCFC–142b may only be used to 

service existing appliances. Consequently, virgin 

HCFC–22, HCFC–142b and blends containing 

HCFC–22 or HCFC–142b may not be used to 

manufacture new pre-charged appliances or 

appliance components or to charge new appliances 

assembled onsite.

requirements and recommendations in 

the MSDS and other safety precautions 

common to the refrigeration and air 

conditioning industry. 

Comparison to other refrigerants: R– 

442A is not ozone-depleting, 

comparable to a number of other 

acceptable non-ozone-depleting 

substitutes for these end uses such as 

HFC–134a, R–410A, and R–404A. R– 

442A’s lack of ozone depletion potential 

is in contrast to some other substitutes, 

such as R–401A, R–414A and other 

blends containing HCFC–22 or HCFC– 

142b 2 with ODPs ranging from about 

0.01 to about 0.047, and HCFC–22 (with 

an ODP of 0.04 3), an ozone-depleting 

substance which it replaces. R–442A’s 

GWP of about 1890 is lower than or 

comparable to that of a number of other 

substitutes in the same refrigeration and 

air conditioning end uses for which we 

are finding it acceptable. For example, 

the GWP for R–442A is lower than that 

of R–404A with a GWP of 3930 and 

comparable to that of R–410A with a 

GWP of 2100. R–442A’s GWP is, 

however, higher than that of HFC–134a 

with a GWP of 1430. The GWP of R– 

442A is also comparable to those of 

ozone depleting substances it is 

replacing, such as HCFC–22 with a GWP 

of 1810. Flammability and toxicity risks 

are low, as discussed above, if used in 

accordance with the MSDSs. EPA finds 

R–442A acceptable for retrofit 

equipment in the end uses listed above 

because the overall environmental and 

human health risk posed by R–442A is 

lower than or comparable to the risks 

posed by other substitutes found 

acceptable in the same end uses for 

retrofit equipment. 

B. Foam Blowing 

1. Commercial Blends of HFC–365mfc 

and HFC–227ea (Solkane® 365/227) 

EPA’s decision: EPA finds 

commercial blends of HFC–365mfc and 

HFC–227ea, containing 7% to 13% 

HFC–227ea and the remainder HFC– 

365mfc, are acceptable as substitutes in: 

• Rigid polyurethane spray 

• Extruded polystyrene, boardstock and 

billet 

HFC–365mfc is also known as 

1,1,3,3,3-pentafluoropropane (CAS Reg. 

No. 138495–42–8), and HFC–227ea is 

also known as 1,1,1,2,3,3,3- 

heptafluoropropane (CAS Reg. No. 431– 

89–0). The manufacturer produces two 

commercial blends for foam blowing, 

one containing 93% HFC–365mfc and 

7% HFC–227ea and the other containing 

87% HFC–365mfc and 13% HFC–227ea, 

and these are marketed under the trade 

name Solkane® 365/227. You may find 

the submission under Docket item EPA– 

HQ–OAR–2003–0118–0278 at http:// 

www.regulations.gov. EPA previously 

listed HFC–365mfc as an acceptable 

substitute for a number of foam blowing 

end uses (September 30, 2009; 74 FR 

50129). 

Environmental information: Blends of 

HFC–365mfc and HFC–227ea have no 

ODP. HFC–365mfc and HFC–227ea have 

100-yr GWPs of 794 and 3220 

respectively. The commercial blends of 

these components, if weighted by mass 

percentage, have GWPs of roughly 900 

to 1100. Both HFC–365mfc and HFC– 

227ea are exempt from the definition of 

VOC under CAA regulations (see 40 

CFR 51.100(s)) addressing the 

development of SIPs to attain and 

maintain the national ambient air 

quality standards. 

Flammability information: By itself, 

HFC–365mfc is flammable. The 

commercial blends of HFC–365mfc and 

HFC–227ea are not flammable as 

formulated. However, care should be 

taken to follow all precautions in the 

MSDS and any guidance from the 

manufacturer, in cases where the nonflammable HFC–227ea may evaporate 

before the flammable component HFC– 

365mfc evaporates, especially with open 

containers of blowing agent or polyol 

premix. 

Toxicity and exposure data: Potential 

health effects of this substitute include 

drowsiness or dizziness. The substitute 

may also irritate the skin or eyes or 

cause frostbite. At sufficiently high 

concentrations, the substitute may cause 

irregular heartbeat, unconsciousness or 

death. The substitute could cause 

asphyxiation if air is displaced by 

vapors in a confined space. These 

potential health effects are common to 

many foam blowing agents. 

EPA anticipates that commercial 

blends of HFC-365mfc and HFC-227ea 

will be used consistent with the 

recommendations specified in the 

MSDSs for the blend and for the 

individual components. For HFC365mfc, HFC-227ea and for the blends, 

the manufacturer recommends an AEL 

of 1000 ppm on an 8-hr TWA. EPA 

anticipates that users will be able to 

meet the manufacturer’s AELs and 

address potential health risks by 

following requirements and 

recommendations in the MSDS and 

other safety precautions common in the 

foam blowing industry. 

Comparison to other foam blowing 

agents: Commercial blends of HFC365mfc and HFC-227ea are non-ozone 

depleting, comparable to a number of 

other acceptable non-ozone-depleting 

substitutes for these end uses, such as 

HFC-245fa, ecomateTM and CO2.

Commercial blends of HFC-365mfc and 

HFC-227ea have no ODP, compared to 

the acceptable substitute trans-1-chloro3,3,3-trifluoroprop-1-ene with an ODP 

of approximately 0.00024 to 0.00034. 

The blends’ lack of ODP is in contrast 

to an ODP of 1.0 for CFC-11 and an ODP 

of 0.12 4 for HCFC-141b, ozone 

depleting substances which they 

replace. The GWPs of the commercial 

blends of HFC-365mfc and HFC-227ea 

of 900 to 1100 are lower than or 

comparable to those of some other 

substitutes in these end uses such as 

HFC-134a with a GWP of 1430 and HFC245fa with a GWP of 1030. The GWP of 

the non-flammable commercial blends 

of HFC-365mfc and HFC-227ea is higher 

than that for some other acceptable, but 

flammable, substitutes such as HFC365mfc 5 alone with a GWP of 794, 

Exxsol Blowing Agents with a GWP less 

than 10 and ecomateTM with a GWP less 

than 5. The GWPs of the commercial 

blends of HFC-365mfc and HFC-227ea 

of 900 to 1100 are higher than those of 

HCFC-141b with a GWP of 725 and are 

lower than CFC-11’s GWP of 4750. 

Flammability and toxicity risks are low, 

as discussed above, if used in 

accordance with the MSDSs. We find 

that commercial blends of HFC-365mfc 

and HFC-227ea are acceptable because 

they do not pose a greater overall risk 

to public health and the environment 

than the other substitutes acceptable in 

the end uses listed above.

Environmental information: 

SolsticeTM 1233zd(E) is not regulated as 

an ODS but it has an ODP of 0.00024 to 

0.00034.6 7 Estimates of this compound’s 

potential to deplete the ozone layer 

found that even with worst-case 

estimates of emissions which assume 

that this compound would substitute for 

all compounds it could replace, the 

impact on global atmospheric ozone 

abundance would be statistically 

insignificant.8 SolsticeTM 1233zd(E) has 

a 100-yr GWP reported as 4.7 to 7 and 

an atmospheric lifetime of 

approximately 26 days.9 10 EPA has 

issued a proposed rule that, if finalized 

as proposed, would exempt SolsticeTM

1233zd(E) from the definition of VOC 

under CAA regulations (see 40 CFR 

51.100(s)) addressing the development 

of SIPs to attain and maintain the 

national ambient air quality standards 

(February 15, 2013; 79 FR 11101,

Flammability information: SolsticeTM

1233zd(E) is not flammable. 

Toxicity and exposure data: Potential 

health effects of this substitute include 

serious eye irritation, skin irritation, or 

frostbite. It may cause central nervous 

system effects such as drowsiness and 

dizziness. It could cause asphyxiation if 

air is displaced by vapors in a confined 

space. 

EPA anticipates that SolsticeTM

1233zd(E) will be used consistent with 

the recommendations specified in the 

manufacturer’s MSDS. The 

manufacturer recommends an AEL of 

300 ppm (8-hr TWA) for SolsticeTM

1233zd(E). EPA also developed a shortterm exposure limit (STEL) of 900 ppm 

over a 15-minute period, based on the 

submitter’s 300 ppm AEL value. EPA 

anticipates that users will be able to 

meet the recommended workplace 

exposure limits (manufacturer’s and 

EPA’s) and address potential health 

risks by following requirements and 

recommendations in the MSDS and 

other safety precautions commonly used 

in the solvent cleaning industry. 

Comparison to other cleaning 

solvents: SolsticeTM 1233zd(E) has an 

ODP of 0.00024 to 0.00034. This is 

higher than the ODP of a number of 

acceptable non-ozone-depleting 

substitutes in these end uses such as 

HFC-4310mee, HFE-7100, acetone, and 

aqueous cleaners. The ODP of 

SolsticeTM 1233zd(E) is comparable to 

the ODPs of trans-1,2-dichloroethylene 

and trichloroethylene and an order of 

magnitude lower than the ODP of 

perchloroethylene, other substitutes in 

the solvent cleaning sector that are not 

regulated as ODS.11 12 SolsticeTM

1233zd(E)’s ODP is several orders of 

magnitude lower than that of ozonedepleting substances it replaces, 

including CFC-113, methyl chloroform, 

HCFC-225ca and HCFC-225cb (ODPs 

ranging from 0.02 to 0.85). SolsticeTM

1233zd(E)’s GWP of 4.7 to 7 is lower 

than that of other substitutes in the 

metals, precision and electronics 

cleaning end uses, such as HFC4310mee with a GWP of 1640 and HFE7100 with a GWP of 297. SolsticeTM

1233zd(E), a non-flammable compound, 

has a GWP that is comparable to or 

slightly higher than that of some other 

acceptable, but flammable, substitutes 

such as trans-1,2-dichloroethylene with 

a GWP less than 10 and acetone with a 

GWP of less than 1. Its climate impacts 

cannot be compared directly to those of 

aqueous cleaners with no direct GWP. 

Furthermore, the GWP of SolsticeTM

1233zd(E) is several orders of magnitude 

less than those of ozone-depleting 

substances it replaces, including methyl 

chloroform, CFC-113, HCFC-225ca and 

HCFC-225cb (GWPs ranging from 122 to 

6,130). Flammability and toxicity risks 

are low, as discussed above, if used in 

accordance with the MSDS. The 

potential health effects of SolsticeTM

1233zd(E) are common to many 

solvents, including many of those 

already listed as acceptable under 

SNAP. EPA finds trans-1-chloro-3,3,3- 

trifluoroprop-1-ene (SolsticeTM

1233zd(E)) acceptable in the end uses 

listed above because the overall 

environmental and human health risk 

posed by SolsticeTM 1233zd(E) is lower 

than or comparable to the risks posed by 

other substitutes found acceptable in the 

same end uses. 

D. Adhesives, Coatings and Inks 

1. Trans-1-chloro-3,3,3-trifluoroprop-1- 

ene (SolsticeTM 1233zd(E)) 

EPA’s decision: EPA finds trans-1- 

chloro-3,3,3-trifluoroprop-1-ene 

acceptable as a substitute carrier solvent 

in: 

• Adhesives 

• Coatings 

Trans-1-chloro-3,3,3-trifluoroprop-1- 

ene ((E) -1-chloro-3,3,3-trifluoroprop-1- 

ene, Chemical Abstracts Service 

Registry Number [CAS Reg. No.] 

102687–65–0) is marketed under the 

trade names SolsticeTM 1233zd(E) and 

SolsticeTM Performance Fluid. EPA 

previously listed trans-1-chloro-3,3,3- 

trifluoroprop-1-ene as an acceptable 

alternative for various CFCs and HCFCs 

in a number of sectors and end uses 

(August 10, 2012, 77 FR 47768). You

Environmental information: The 

environmental information for this 

substitute is set forth in the 

‘‘Environmental information’’ section in 

listing C.1. above. 

Flammability information: SolsticeTM

1233zd(E) is not flammable. 

Toxicity and exposure data: The 

toxicity information for this substitute is 

set forth in the ‘‘Toxicity and exposure 

data’’ section in listing C.1. above. 

EPA anticipates that SolsticeTM

1233zd(E) will be used consistent with 

the recommendations specified in the

manufacturer recommends an AEL of 

300 ppm (8-hour TWA) for SolsticeTM

1233zd(E). EPA also developed a STEL 

of 900 ppm over a 15-minute period,

requirements and recommendations in 

the MSDS and other safety precautions 

common when using adhesives or 

coatings. 

Comparison to other carrier solvents 

in adhesives and coatings: SolsticeTM

1233zd(E) has an ODP of 0.00024 to 

0.00034. This is higher than the ODP of 

a number of substitutes in these end 

uses such as HFE-7100, acetone and 

ultraviolet-cured formulations and is 

comparable to the ODP of trans-1,2- 

dichloroethylene, another acceptable 

substitute in the adhesives and coatings 

end uses that is not regulated as an 

ODS.13 14 SolsticeTM 1233zd(E)’s ODP is 

several orders of magnitude lower than 

those of ozone-depleting substances it 

replaces, including methyl chloroform 

and HCFC-141b (ODPs respectively of 

0.16 and 0.012). SolsticeTM 1233zd(E)’s 

GWP of 4.7 to 7 is lower than that of 

some substitutes in the adhesives and 

coatings end uses, such as HFE-7100 

with a GWP of 297. SolsticeTM

1233zd(E), a non-flammable compound, 

has a GWP that is comparable to or 

slightly higher than that of some other 

acceptable, but flammable, substitutes 

such as trans-dichloroethylene with a 

GWP less than 10 and acetone with a 

GWP of less than one. Its climate 

impacts cannot be compared directly to 

those of ultraviolet-cured formulations 

with no direct GWP. Furthermore, the 

GWP of SolsticeTM 1233zd(E) is one to 

two orders of magnitude less than those 

of methyl chloroform and HCFC-141b, 

ozone-depleting substances in these end 

uses (GWPs ranging from 146 to 725). 

Flammability and toxicity risks are low, 

as discussed above, if used in 

accordance with the MSDS. The 

potential health effects of SolsticeTM

1233zd(E) are common to many carrier 

solvents, including many of those 

already listed as acceptable under 

SNAP. EPA finds trans-1-chloro-3,3,3- 

trifluoroprop-1-ene (SolsticeTM

1233zd(E)) acceptable in the end uses 

listed above because the overall 

environmental and human health risk 

posed by SolsticeTM 1233zd(E) is lower 

than or comparable to the risks posed by 

other substitutes found acceptable in the 

same end uses. 

E. Fire Suppression 

1. K-Ace 

EPA’s decision: EPA finds K-Ace 

acceptable as a substitute for total 

flooding uses in both occupied and 

unoccupied areas. 

K-Ace is a blend by weight of 50% 

percent potassium acetate, which is also 

known as C2H3KO2 (CAS Reg. No. 127– 

08–2), and 50% water (CAS Reg. No. 

7732–18–5). You may find the 

submission under Docket item EPA– 

HQ–OAR–2003–0118–0320 

(continuation of Air Docket A–91–42) at 

http://www.regulations.gov. 

Environmental information: K-Ace 

has no ODP and no GWP. K-Ace does 

not contain any VOC as defined under 

CAA regulations (see 40 CFR 51.100(s)) 

addressing the development of SIPs to 

attain and maintain the national 

ambient air quality standards. 

K-Ace is expected to aerosolize 

rapidly during expulsion from the fire 

suppression system and then settle as a 

salt water film on surfaces in the space 

being protected, rather than becoming 

airborne and moving to surface waters. 

After settling, cleanup would involve 

confining the release and recovering as 

much of the solution as possible, and 

washing or rinsing of surfaces. During 

cleanup, we recommend that discharges 

of K-Ace be disposed of in accordance 

with local, state, and federal 

requirements and the manufacturer’s 

MSDS. 

Flammability information: K-Ace is 

not flammable. 

Toxicity and exposure data: K-Ace is 

not expected to pose a risk to human 

health, as the active ingredient is 

potassium acetate, which is commonly 

used in pharmaceuticals, foods, and 

textiles. Potassium acetate is approved 

by the U.S. Food and Drug 

Administration (FDA) as a synthetic 

flavoring (21 CFR 172.515) and to treat 

diabetic ketoacidosis via injection (FDA 

Application No. NDA 018896). 

Potassium acetate may cause 

gastrointestinal discomfort or minor 

irritation to the eyes, skin, or respiratory 

tract. Given the low toxicity of its 

constituents, EPA expects no adverse 

health effects when the recommended 

safety precautions and normal industry 

practices are applied and use of the 

substitute is in accordance with the 

manufacturer’s MSDS. To minimize 

worker exposure to any chemicals 

during manufacture, installation, and 

maintenance through an accidental 

release or spill, EPA has outlined the 

following recommendations in 

accordance with established good 

manufacturing practices: 

• Training in safe handling 

procedures for employees that would 

likely handle containers of K-Ace or 

extinguishing units filled with the 

material; 

• Use of PPE selected in accordance 

with the OSHA Technical Manual by 

employees handling the proposed 

substitute; 

• Adequate ventilation; 

• Clean-up of all spills immediately 

in accordance with good industrial 

hygiene practices. 

Comparison to other fire 

suppressants: K-Ace has no ODP or 

GWP. K-Ace’s ODP of zero is 

comparable to those of other acceptable 

non-ozone-depleting substitutes for this 

end use, such as Cold Fire®, Inert Gas 

541, HFC-227ea, and HFC-125, and in 

contrast to Halon 1301, an ODS which 

it replaces, with an ODP of 16.. K-Ace’s 

GWP of zero is less than that of a 

number of other acceptable substitutes 

for this end use, such as HFC-227ea 

with a GWP of 3220 and HFC-125 with 

a GWP of 3500 and is comparable to that 

of other acceptable substitutes for this 

end use, such as Cold Fire® with a GWP 

of 0 and Inert Gas 541 with a GWP of 

0. Furthermore, K-Ace’s GWP is lower 

than that of Halon 1301, an ODS it 

replaces, with a direct GWP of 7140. 

Toxicity risks are low, as discussed 

above, if used in accordance with the 

MSDS. EPA finds K-Ace acceptable in 

the end use listed above because the 

overall environmental and human 

health risk posed by K-Ace is lower than 

or comparable to the risks posed by 

other substitutes found acceptable in the 

same end use. 

II. Section 612 Program 

A. Statutory Requirements and 

Authority for the SNAP Program 

Section 612 of the Clean Air Act 

(CAA) requires EPA to develop a 

program for evaluating alternatives to 

ozone-depleting substances (ODSs). EPA 

refers to this program as the Significant 

New Alternatives Policy (SNAP) 

program. The major provisions of 

section 612 are: 

1. Rulemaking 

Section 612(c) requires EPA to 

promulgate rules making it unlawful to 

replace any class I substance 

(chlorofluorocarbon, halon, carbon 

tetrachloride, methyl chloroform, and 

hydrobromofluorocarbon) or class II 

substance (hydrochlorofluorocarbon) 

with any substitute that the 

Administrator determines may present 

adverse effects to human health or the 

environment where the Administrator 

has identified an alternative that (1) 

reduces the overall risk to human health 

and the environment, and (2) is 

currently or potentially available. 

2. Listing of Unacceptable/Acceptable 

Substitutes 

Section 612(c) requires EPA to 

publish a list of the substitutes 

unacceptable for specific uses and to 

publish a corresponding list of 


wreier-aviles on DSK5TPTVN1PROD with RULES
Federal Register / Vol. 78, No. 96 / Friday, May 17, 2013 / Rules and Regulations 29039 

15As defined at 40 CFR 82.104, ‘‘interstate 

commerce’’ means the distribution or transportation 

of any product between one state, territory, 

possession or the District of Columbia, and another 

state, territory, possession or the District of 

Columbia, or the sale, use or manufacture of any 

product in more than one state, territory, possession 

or District of Columbia. The entry points for which 

a product is introduced into interstate commerce 

are the release of a product from the facility in 

which the product was manufactured, the entry into 

a warehouse from which the domestic manufacturer 

releases the product for sale or distribution, and at 

the site of United States Customs clearance. 

16As defined at 40 CFR 82.172, ‘‘end-use’’ means 

processes or classes of specific applications within 

major industrial sectors where a substitute is used 

to replace an ODS. 

17The SNAP regulations also include ‘‘pending,’’ 

referring to submissions for which EPA has not 

reached a determination, under this provision. 

acceptable alternatives for specific uses. 

The list of acceptable substitutes may be 

found at http://www.epa.gov/ozone/ 

snap/lists/index.html and the lists of 

‘‘unacceptable,’’ ‘‘acceptable subject to 

use conditions,’’ and ‘‘acceptable 

subject to narrowed use limits’’ 

substitutes are found in the appendices 

to subpart G of 40 CFR part 82. 

3. Petition Process 

Section 612(d) grants the right to any 

person to petition EPA to add a 

substance to, or delete a substance from, 

the lists published in accordance with 

section 612(c). The Agency has 90 days 

to grant or deny a petition. Where the 

Agency grants the petition, EPA must 

publish the revised lists within an 

additional six months. 

4. 90-Day Notification 

Section 612(e) directs EPA to require 

any person who produces a chemical 

substitute for a class I substance to 

notify the Agency not less than 90 days 

before new or existing chemicals are 

introduced into interstate commerce for 

significant new uses as substitutes for a 

class I substance. The producer must 

also provide the Agency with the 

producer’s unpublished health and 

safety studies on such substitutes. 

5. Outreach 

Section 612(b)(1) states that the 

Administrator shall seek to maximize 

the use of federal research facilities and 

resources to assist users of class I and 

II substances in identifying and 

developing alternatives to the use of 

such substances in key commercial 

applications. 

6. Clearinghouse 

Section 612(b)(4) requires the Agency 

to set up a public clearinghouse of 

alternative chemicals, product 

substitutes, and alternative 

manufacturing processes that are 

available for products and 

manufacturing processes which use 

class I and II substances. 

B. EPA’s Regulations Implementing 

Section 612 

On March 18, 1994, EPA published 

the original rulemaking (59 FR 13044) 

which established the process for 

administering the SNAP program and 

issued EPA’s first lists identifying 

acceptable and unacceptable substitutes 

in the major industrial use sectors 

(subpart G of 40 CFR part 82). These 

sectors—refrigeration and air 

conditioning; foam blowing; cleaning 

solvents; fire suppression and explosion 

protection; sterilants; aerosols; 

adhesives, coatings and inks; and 

tobacco expansion—are the principal 

industrial sectors that historically 

consumed the largest volumes of ODS. 

Section 612 of the CAA requires EPA 

to list as acceptable those substitutes 

that do not present a significantly 

greater risk to human health and the 

environment as compared with other 

substitutes that are currently or 

potentially available. 

C. How the Regulations for the SNAP 

Program Work 

Under the SNAP regulations, anyone 

who plans to market or produce a 

substitute to replace a class I substance 

or class II substance in one of the eight 

major industrial use sectors must 

provide notice to the Agency, including 

health and safety information on the 

substitute, at least 90 days before 

introducing it into interstate commerce 

for significant new use as an alternative. 

40 CFR 82.176(a). This requirement 

applies to the persons planning to 

introduce the substitute into interstate 

commerce,15 which typically are 

chemical manufacturers but may 

include importers, formulators, 

equipment manufacturers, and endusers when they are responsible for 

introducing a substitute into 

commerce.16 The 90-day SNAP review 

process begins once EPA receives the 

submission and determines that the 

submission includes complete and 

adequate data. 40 CFR 82.180(a). The 

CAA and the SNAP regulations, 40 CFR 

82.174(a), prohibit use of a substitute 

earlier than 90 days after notice has 

been provided to the Agency. 

The Agency has identified four 

possible decision categories for 

substitutes that are submitted for 

evaluation: acceptable; acceptable 

subject to use conditions; acceptable 

subject to narrowed use limits; and 

unacceptable 17 (40 CFR 82.180(b)). Use 

conditions and narrowed use limits are 

both considered ‘‘use restrictions’’ and 

are explained below. Substitutes that are 

deemed acceptable with no use 

restrictions (no use conditions or 

narrowed use limits) can be used for all 

applications within the relevant enduses within the sector. Substitutes that 

are acceptable subject to use restrictions 

may be used only in accordance with 

those restrictions. 

After reviewing a substitute, the 

Agency may make a determination that 

a substitute is acceptable only if certain 

conditions in the way that the substitute 

is used are met to minimize risks to 

human health and the environment. 

EPA describes such substitutes as 

‘‘acceptable subject to use conditions.’’ 

Entities that use these substitutes 

without meeting the associated use 

conditions are in violation of EPA’s 

SNAP regulations. 40 CFR 82.174(c). 

For some substitutes, the Agency may 

permit a narrowed range of use within 

an end-use or sector. For example, the 

Agency may limit the use of a substitute 

to certain end-uses or specific 

applications within an industry sector. 

EPA describes these substitutes as 

‘‘acceptable subject to narrowed use 

limits.’’ A person using a substitute that 

is acceptable subject to narrowed use 

limits in applications and end-uses that 

are not consistent with the narrowed 

use limit is using the substitute in an 

unacceptable manner and is in violation 

of section 612 of the CAA and EPA’s 

SNAP regulations. 40 CFR 82.174(c). 

The Agency publishes its SNAP 

program decisions in the Federal 

Register (FR). EPA publishes decisions 

concerning substitutes that are deemed 

acceptable subject to use restrictions 

(use conditions and/or narrowed use 

limits), or substitutes deemed 

unacceptable, as proposed rulemakings 

to provide the public with an 

opportunity to comment, before 

publishing final decisions. 

In contrast, EPA publishes decisions 

concerning substitutes that are deemed 

acceptable with no restrictions as 

‘‘notices of acceptability’’ or 

‘‘determinations of acceptability,’’ rather 

than as proposed and final rules. As 

described in the preamble to the rule 

initially implementing the SNAP 

program in the Federal Register at 59 

FR 13044 on March 18, 1994, EPA does 

not believe that rulemaking procedures 

are necessary to list alternatives that are 

acceptable without restrictions because 

such listings neither impose any 

sanction nor prevent anyone from using 

a substitute.
