AGENCY

40 CFR Part 82

[FRL–5139–7]

Protection of Stratospheric Ozone

AGENCY: Environmental Protection

Agency.

ACTION: Notice of acceptability.

SUMMARY: This notice expands the list of

acceptable substitutes for ozone

depleting substances (ODSs) under the

U.S. Environmental Protection Agency’s

(EPA) Significant New Alternatives

Policy (SNAP) program. SNAP

implements section 612 of the amended

Clean Air Act of 1990 which requires

EPA to evaluate substitutes for the

ODSs, and regulate the use of

substitutes where other alternatives

exist that reduce overall risk to human

health and the environment. Through

these evaluations, SNAP generates lists

of acceptable and unacceptable

substitutes for each of the major

industrial use sectors.

On March 18, 1994, EPA promulgated

its plan for administering the SNAP

program, and issued decisions on the

acceptability and unacceptability of a

number of substitutes (59 FR 13044). In

today’s Notice, EPA issues decisions on

the acceptability of substitutes not

previously reviewed by the Agency. The

intended effect of this action is to

expedite movement away from ozone

depleting compounds. To arrive at

determinations on the acceptability of

substitutes, the Agency completed a

cross-media sector end-use screening

assessment of risks to human health and

the environment.

EFFECTIVE DATE: January 13, 1995.

Appendix A Summary of Acceptable and

Pending Decisions

II. Section 612 Program

A. Statutory Requirements

Section 612 of the Clean Air Act

authorizes EPA to develop a program for

evaluating alternatives to ozonedepleting substances. EPA is referring to

this program as the Significant New

Alternatives Policy (SNAP) program.

The major provisions of section 612 are:

Rulemaking—Section 612(c) requires

EPA to promulgate rules making it

unlawful to replace any class I

(chlorofluorocarbon, halon, carbon

tetrachloride, methyl chloroform,

methyl bromide, and

hydrobromofluorocarbon) or class II

(hydrochlorofluorocarbon) substance

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.

Listing of Unacceptable/Acceptable

Substitutes—Section 612(c) also

requires EPA to publish a list of the

substitutes unacceptable for specific

uses. EPA must publish a corresponding

list of acceptable alternatives for

specific uses.

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 6 months.

90-day Notification—Section 612(e)

requires 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.

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.

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. Regulatory History

On March 18, 1994, EPA published

the Final Rulemaking (FRM) (59 FR

13044) which described the process for

administering the SNAP program and

issued EPA’s first acceptability lists for

substitutes in the major industrial use

sectors. These sectors include:

refrigeration and air conditioning; foam

blowing; solvent cleaning; fire

suppression and explosion protection;

sterilants; aerosols; adhesives, coatings

and inks; and tobacco expansion. These

sectors compose the principal industrial

sectors that historically consumed the

largest volumes of ozone-depleting

compounds.

As described in the final rule for the

SNAP program (59 FR 13044), EPA does

not believe that rulemaking procedures

are required to list alternatives as

acceptable with no limitations. Such

listings do not impose any sanction, nor

do they remove any prior license to use

a substance. Consequently, EPA is

adding substances to the list of

acceptable alternatives without first

requesting comment on new listings.

EPA does, however, believe that

notice-and-comment rulemaking is

required to place any substance on the

list of prohibited substitutes, to list a

substance as acceptable only under

certain conditions, to list substances as

acceptable only for certain uses, or to

remove a substance from either the list

of prohibited or acceptable substitutes.

Updates to these lists are published as

separate notices of rulemaking in the

Federal Register.

The Agency defines a ‘‘substitute’’ as

any chemical, product substitute, or

alternative manufacturing process,

whether existing or new, that could

replace a class I or class II substance.

Anyone who produces a substitute must

provide the Agency with health and

safety studies on the substitute at least

90 days before introducing it into

interstate commerce for significant new

use as an alternative. This requirement

applies to substitute manufacturers, but
Federal Register / Vol. 60, No. 9 / Friday, January 13, 1995 / Rules and Regulations 3319

may include importers, formulators or

end-users, when they are responsible for

introducing a substitute into commerce.

Since the SNAP FRM, EPA has

published a Notice listing acceptable

alternatives on August 26, 1994 and a

Notice of Proposed Rulemaking

restricting the use of certain substitutes

on September 26, 1994.

III. Listing of Acceptable Substitutes

This section presents EPA’s most

recent acceptable listing decisions for

class I substitutes in the following

industrial sectors: refrigerants and air

conditioning, foam blowing, solvent

cleaning, fire suppression and explosion

protection; sterilants; aerosols;

adhesives, coatings and inks. These

decisions represent substitutes not

previously reviewed in the final

rulemaking for SNAP (59 FR 13044;

March 18, 1994) and, consequently, add

to the lists of acceptable substitutes

under SNAP. For copies of the full list,

contact the EPA Stratospheric

Protection Hotline at the number listed

in Section V of this Notice.

Parts A through D below present a

detailed discussion of the substitute

listing determinations by major use

sector. Tables summarizing listing

decisions in this Notice are in Appendix

A. The comments contained in

Appendix A provide additional

information on a substitute, but like the

listings themselves, are not regulatory in

nature. Thus, adherence to

recommendations in the comments are

not mandatory for use of a substitute. In

addition, the comments should not be

considered comprehensive with respect

to other legal obligations pertaining to

the use of the substitute. However, EPA

encourages users of acceptable

substitutes to apply all comments to

their use of these substitutes. In many

instances, the comments simply allude

to sound operating practices that have

already been identified in existing

industry and/or building-code

standards. Thus, many of the comments,

if adopted, would not require significant

changes in existing operating practices

for the affected industry.

A. Refrigeration and Air Conditioning

Please refer to the final SNAP rule for

detailed information pertaining to the

designation of end-uses, additional

requirements imposed under sections

608 and 609, and other information

related to the use of alternative

refrigerants.

1. R–401A and R–401B

R–401A and R–401B, which consist of

HCFC–22, HFC–152a, and HCFC–124,

are acceptable as substitutes for CFC–

11, CFC–12, R–500, and R–502 in the

following end-uses:

• New and Retrofitted Reciprocating

Chillers.

• New Industrial Process

Refrigeration.

• New Cold Storage Warehouses.

• New Refrigerated Transport.

• New Retail Food Refrigeration.

• New Commercial Ice Machines.

• New Vending Machines.

• New Water Coolers.

• New Household Refrigerators.

• New Household Freezers.

• New Residential Dehumidifiers.

Please note that different temperature

regimes may affect the applicability of

these substitutes within these end-uses.

Two of the constituents in these

blends are HCFCs and thus contribute to

ozone depletion; HCFC production will

be phased out according to the

accelerated schedule. While the GWP of

HCFC–22 is somewhat high, refrigerant

leak regulations should reduce its

contribution to global warming. The

GWPs of the other components are low.

Although these blends do contain one

flammable constituent, HFC–152a, the

blends themselves are not flammable. In

addition, each blend is a near azeotrope,

and it does not fractionate in normal

operation. Finally, leak testing of each

blend demonstrated that while the

vapor and liquid compositions changed,

neither phase became flammable.

Testing of these blends with centrifugal

compressors is inadequate, and

therefore such use is not recommended

by the manufacturer. Further testing

may resolve this uncertainty.

2. CO2

CO2 is acceptable as follows:

• As a substitute for CFC–13, R–13B1,

and R–503 in Very Low Temperature

Refrigeration, Retrofit and New.

• As a substitute for CFC–13, R–13B1,

and R–503 in Industrial Process

Refrigeration, Retrofit and New.

• As a substitute for CFC–11, CFC–12,

CFC–113, CFC–114, and CFC–115 in

Non-mechanical Heat Transfer, Retrofit

and New.

CO2 was historically used in

refrigeration systems. It is a well-known,

nontoxic, nonflammable gas. Its GWP is

defined as 1, and all other GWPs are

indexed to it. Since it is readily

available as a waste gas, no additional

chemical will need to be produced.

Thus, the use of CO2 as a refrigerant will

not contribute to global warming. CO2’s

usefulness is limited to temperatures

above ¥70°F.

3. HCFC–22

HCFC–22 is acceptable as a substitute

for R–400(60/40) and CFC–114 in New

Industrial Process Air Conditioning.

EPA recommends that HCFC–22 only

be used where ambient temperatures are

lower than 115°F because of very high

system pressures.

HCFC–22 has been used in a variety

of air conditioning and refrigeration

applications for many years. HCFC–22

contributes to ozone depletion and is

considered a transitional alternative.

HCFC–22 production will be phased out

according to the accelerated phaseout

schedule. HCFC–22’s GWP and

atmospheric lifetime are higher than

other HCFCs. HCFC–22 is not

flammable and it is compatible with

existing oils used in most refrigeration

and air conditioning equipment.

4. HFC–134a

HFC–134a is acceptable as a

substitute for R–400(60/40) and CFC–

114 in New Industrial Process Air

Conditioning.

EPA recommends that HFC–134a only

be used where ambient temperatures are

lower than 125°F because of very high

system pressures. HFC–134a does not

contribute to ozone depletion. HFC–

134a’s GWP and atmospheric lifetime

are close to those of other alternatives

which are acceptable in this end-use.

While HFC–134a is compatible with

most existing refrigeration and air

conditioning equipment parts, it is not

compatible with the mineral oils

currently used in such systems. An

appropriate ester-based, polyalkylene

glycol-based, or other type of lubricant

should be used.

5. R–401A

R–401A and R–401B, which consist of

HCFC–22, HFC–152a, and HCFC–124, is

acceptable as a substitute for R–400(60/

40) and CFC–114 in Retrofitted

Industrial Process Air Conditioning.

See the discussion on R–401A for

more information about this blend.

6. R–404A

R–404A, which consists of HFC–125,

HFC–143a, and HFC–134a, is acceptable

as a substitute for CFC–12 in new

household refrigerators.

None of this blend’s constituents

contains chlorine, and thus this blend

poses no threat to stratospheric ozone.

However, HFC–125 and HFC–143a have

very high GWPs, and the GWP of HFC–

134a is somewhat high. EPA strongly

encourages recycling and reclamation of

this blend in order to reduce its direct

global warming impact. Although HFC–

143a is flammable, the blend is not.

Leak testing has demonstrated that its

composition never becomes flammable.
3320 Federal Register / Vol. 60, No. 9 / Friday, January 13, 1995 / Rules and Regulations

7. R–507

R–507, which consists of HFC–125

and HFC–143a, is acceptable as a

substitute for CFC–12 in new household

refrigerators.

None of this blend’s constituents

contains chlorine, and thus this blend

poses no threat to stratospheric ozone.

However, HFC–125 and HFC–143a have

very high GWPs. EPA strongly

encourages recycling and reclamation of

this blend in order to reduce its direct

global warming impact. Although HFC–

143a is flammable, the blend is not.

Leak testing has demonstrated that its

composition never becomes flammable.

8. Hydrocarbon Blend B

Hydrocarbon Blend B is acceptable as

a substitute for CFC–12 in retrofitted

and new industrial process refrigeration

systems.

This blend contains several

hydrocarbons. It does not contribute to

ozone depletion, nor does it contribute

significantly to global warming. This

blend contains flammable refrigerants,

and EPA recommends but does not

require that it only be used at industrial

facilities which already manufacture or

use hydrocarbons in the process stream.

Such facilities are designed to comply

with the safety standards required for

managing flammable chemicals. Note

that EPA only finds this product

acceptable in this specific end-use

because other flammable refrigerants are

acceptable and sufficient occupational

safety rules exist to protect workers.

B. Foams

1. Rigid Polyurethane Appliance

a.Vacuum Panels—Vacuum panels

are acceptable substitutes for CFC–11

blown rigid polyurethane appliance

foam. The Agency has reviewed data on

existing and proposed models of

vacuum panels and believes that this

alternative technology offers lower risk

than continued use of CFC–11 blown

polyurethane foam.

IV. Substitutes Pending Review

The Agency describes submissions as

pending if data are incomplete or for

which the 90-day review period is

underway and EPA has not yet reached

a final decision. For submissions that

are incomplete, the Agency will contact

the submitter to determine a schedule

for providing the missing information if

the Agency needs to extend the 90-day

review period. EPA will use its

authority under section 114 of the Clean

Air Act to gather this information, if

necessary. Any delay of the review

period does not affect a manufacturer’s

ability to sell a product 90 days after

notification of the Agency. Substitutes

currently pending completion of review

are listed in Appendix A.
