**1. INSTRUCTIONS FOR COMPLETING THE SNAP INFORMATION NOTICE**

**A. General Instructions**

The Significant New Alternatives Policy (SNAP) program is a regulatory
program developed pursuant to section 612 of the Clean Air Act (CAA).
SNAP is designed to :

> \$ Identify and evaluate substitutes for class I and class II
> ozone-depleting substances (ODSs)
>
> \$ Look at overall risk to human health and the environment of both
> existing and new substitutes
>
> \$ Publish lists of acceptable and unacceptable substitutes by end-use
>
> \$ Promote the use of acceptable substitutes for ozone-depleting
> compounds

To arrive at determinations on the acceptability of substitutes, the
Agency performs a cross-media analysis of risks to human health and the
environment from the use of various substitutes in different industrial
and consumer uses. The SNAP program evaluates substitutes in the
following sectors:

\$ refrigeration and air-conditioning

\$ foam blowing

\$ solvent cleaning

\$ fire suppression and explosion protection

\$ tobacco expansion

\$ adhesives, coatings and inks

\$ aerosols

\$ sterilants

For additional information on the SNAP program and a copy of the
existing listing decisions, please call the Stratospheric Ozone Hotline
at (800) 296-1996.

For the purposes of this document, EPA is using the word \"substitute\"
as a synonym for \"alternative\". As defined in the final SNAP rule (59
[FR]{.underline} 13044), a substitute is \"any chemical, product
substitute, or alternative manufacturing process, whether existing or
new, intended for use as a replacement for a class I or II compound.\"

You must file a separate notice for each substitute you submit for
evaluation. However, a single alternative may be submitted for multiple
end-uses simultaneously provided that the appropriate information is
submitted for each specific end-use. See Appendix A for a list of sector
end-uses included under SNAP. If you submit a substitute for review
under more than one sector, you may wish to complete a separate notice
for each sector.

Please type the SNAP form or print legibly in black ink. All information
must be in English. Provide all information requested on the notice form
to the extent that you know or can reasonably ascertain it. If you do
not know or cannot reasonably ascertain the information, enter
\"unknown\" (for not known). However, if you cannot answer question that
is needed for evaluation of the substitute within a given sector (see
Appendix B), review of the substitute may be delayed. You may attach
continuation sheets to any subsection or item on the form. You may
photocopy the notice form, sections of the form, or this manual as
frequently as you need. In fact, EPA suggests you make a clean copy of
the form for future use before adding any information.

The SNAP staff includes specialists in each of the industrial use
sectors for which substitutes must be submitted. EPA recommends that you
contact the appropriate sector specialist before submitting your
application to ensure completeness. Please call the Hotline at
1-800-296-1996 to be referred to the appropriate person.

Send your completed submission notice to the SNAP Document Control
Officer (6205J), whose address appears on page 1 of the form. You must
submit three copies of the submission to EPA. If information is claimed
as confidential, it must be removed from one of the copies, which will
be placed in the public docket; the other two copies must include all
confidential material. If you do not claim any information as
confidential, all copies must be identical. (See below for further
guidance on handling of confidential information under SNAP.)

There is no application fee for submitting information to the SNAP
program.

**B. Confidentiality Claims**

1\. Asserting Claims

If you submit information for which you request Confidential Business
Information (CBI) status, you must assert a claim of confidentiality at
the time of submission. If you do not assert a claim of confidentiality
at the time of submission, EPA may disclose the information to the
public without further notice to you. Information which is publicly
available (e.g., in journals, trade magazines, product literature, etc.)
cannot be claimed as CBI. Requesting CBI status for such public
information could delay review under section 612. All claims of
confidentiality will be treated in a manner consistent with 40 CFR Part
2, Subpart B.

In addition, you should be aware that under CAA section 114(c),
emissions data may not be claimed as confidential. There are other
instances in which confidentiality assertions may later be reconsidered,
even when confidentiality claims are originally received. This could
occur, for example, when a Freedom of Information Act (FOIA) request on
a particular substitute is received by the Agency. These circumstances
and others are described in the provisions of 40 CFR Part 2, Subpart B.
You will be contacted as part of this evaluation process if and when any
reconsideration of the confidential status of your data occurs.

To claim information as CBI, circle or bracket the
[specific]{.underline} infor­mation you claim as confi­dential and check
the box at the bottom of the page. Then pro­vide substantia­tion of this
claim on an attachment to the notice. EPA requires substantiation of all
CBI claims under SNAP or a submission will be considered incomplete. For
example, if you submit a study which describes a physical or chemical
property and it is only that property which you wish to claim as
confidential, bracket only that property. Do not simply stamp
\"Confidential\" on the page which contains that property.

If you claim the identity or formulation of a substitute as
confidential, you must provide a generic description of this
information. In addition to guidance on developing generic names that is
provided in Section 1.F. of this document, EPA strongly recommends
contacting the appropriate sector specialist for assistance in this
area.

As stated above, you must provide three copies of your submission. If
you do not claim any information as confidential, all copies must be
identical. When portions of the submission are claimed as CBI, however,
only two copies should include CBI material. To ensure that no
confidential information is disclosed to the public, you must delete all
CBI from the third \"sanitized\" copy, including attachments, which will
become part of the public docket. The following special preparation is
required for the third copy:

> \$ Remove from the body of the submission any information you claim as
> confidential. Replace with generic information if it is available.
>
> \$ Mark the third copy plainly on both its cover and its title page
> with the phrase \"Public Docket Material \-- contains no information
> claimed as confidential.\"

If you claim CBI but do not provide the sanitized copy with your
submission, the submission will be incomplete and an acceptability
determination on your product will not be published. EPA recognizes that
substantial portions of submissions may be omitted from the public
docket copy. However, all CBI claims must be substantiated to warrant
restricting access to such information.

2\. Substantiating CBI Claims

EPA requires substantiation of all confidentiality claims at the time of
submission. In making these claims, the following provisions apply:

> \$ The specific information to which the claim applies must be clearly
> marked in the body of the study as subject to a claim of
> confidentiality;
>
> \$ A \`Supplemental Statement of Data Confidentiality Claims\' must be
> submitted, identifying each section claimed confidential and
> describing in detail the basis for the claim. (See below for specific
> points that should be addressed);
>
> \$ The \`Supplemental Statement of Data Confidentiality Claims\' must
> be signed and dated and must include the typed name and title of the
> official who signed it.

If you do not provide the required substantiation when submitting
information claimed as confidential, EPA may make the complete submitted
information available to the public without further notice.

[Supplemental Statement of Data Confidentiality Claims]{.underline}

For any portion of a submission that you claim as confidential, the
following information must be included within a Supplementary Statement
of Data Confidentiality Claims:

> \$ Identify specifically by page and line number(s) each portion of
> the study for which you claim confidentiality.
>
> \$ Give the reasons why the cited passage qualifies for confidential
> treatment.
>
> \$ Indicate the length of time - until a specific date or event, or
> permanently - for which the information should be treated as
> confidential.
>
> \$ Identify the measures taken to guard against undesired disclosure
> of this information.
>
> \$ Describe the extent to which the information has been disclosed,
> and what precautions have been taken in connection with these
> disclosures.
>
> \$ Enclose copies of any determinations of confidentiality made by
> EPA, other Federal agencies, or courts concerning this information.
>
> \$ If you assert that disclosure of this information would be likely
> to result in substantial harmful effects to you, describe those
> harmful effects and explain why they should be viewed as substantial.
>
> \$ If you assert that the information is voluntarily submitted,
> indicate whether you believe disclosure of this information might tend
> to lessen the availability to EPA of similar information in the
> future, and if so, how.

3\. Confidentiality Provisions for Toxicity Data

Toxicity or health and safety studies, to the extent that confidential
treatment is prohibited under the Toxic Substances Control Act (TSCA) or
the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), cannot
be held confidential. However, other information can be maintained as
confidential subject to the provisions of 40 CFR, Part 2, Subpart B, so
long as it is: a) any information other than emissions data contained in
the toxicity study, b) not health and safety data, and c) not relevant
to the effects of a substance on human health and the environment (e.g.,
discussion of process information, proprietary blends). The Agency is
therefore requesting that you do not identify the following information
as confidential: all information concerning the objectives, methodology,
results, or significance of any toxicity test or experiment performed on
or with a substitute or its degradation products; any information
concerning the effects of the substitute on any organism (e.g., fish,
wildlife, humans and other mammals) or the environment (e.g., studies
related to persistence, translocation, and fate); and
pharmacokinetics/metabolism studies.

4\. Contractor Access

Information submitted as CBI may be ac­cessed by companies desig­nated as
Autho­rized Repre­sen­tatives of the United States Envi­ronmental Protec­tion
Agency (EPA) under an EPA con­tract for the purpose of assisting EPA in
the development and imple­menta­tion of national regula­tions for the
protection of stratospheric ozone, including the develop­ment of the SNAP
program. These Autho­rized Representatives may have access to any
information received by the Stratospheric Protection Division within
EPA\'s Office of Atmospheric Pro­grams for use in reviewing the need for
possible con­trol of any substance, practice, process or activity that
may rea­sonably be anticipated to affect strato­spheric ozone. In general,
this informa­tion will pertain to the feasibili­ty, costs, and
environmen­tal and health impacts of using substitutes for class I and
class II substances. Access to such infor­mation is necessary to ensure
that these companies can complete the work required by the contract.

Authorized Representatives of EPA are subject to the provi­sions of 42
U.S.C. 7414(c) respecting confidential business infor­mation as
implemented by 40 CFR 2.301(h).

**C. Test Data and Other Data**

You are required to provide test data on the health and environmental
effects of alternatives, including data on physical/chemical properties,
in your possession or control, and a description of any other health and
environmental effects data on the substance known to or reasonably
ascertainable by you. **The Agency holds the position that data in the
possession or in control of either a parent company or an affiliated
subsidiary located outside the U.S. are considered data that should be
known to or reasonably ascertainable by a submitter.**

Complete test data, not summaries of data, must be submitted if they do
not appear in the published literature. Incomplete reports (e.g. from
ongoing studies) are exempt from full reporting. However, you must
describe the nature and objective of any incomplete study, report, or
test; the name and address of any laboratory developing the data;
progress to date, type of data collected; significant preliminary
results; and an anticipated completion date. If significant preliminary
results or final results are obtained prior to the completion of the
notice review period or any other additional information significant to
the review of the notice becomes available to you, you must submit this
information within 10 days of receipt. If information becomes available
during the last 5 days of the review period, you should
[immediately]{.underline} inform EPA by telephone. **Data must be
submitted in English.**

Examples of the types of test data you must submit for each sector are
provided in Appendix B at the end of this manual. For additional
information on health and safety studies and on submitting test data,
see \'82.172 and 82.178 of the SNAP Rule and Section 1.F. of these
instructions.

**D. Who Must Submit a SNAP Information Notice**

1\. Designated Submitters

As required by section 612(e) of the Clean Air Act Amendments (CAAA) of
1990, anyone who produces a substitute for a class I ozone-depleting
substance must provide the Agency with that person\'s unpublished health
and safety studies on the substitute, as well as notify the Agency at
least 90 days before introducing the substitute or a product using the
substitute into interstate commerce for significant new use as an
alternative. Also, pursuant to sections 114, 301 and 612(c), producers
of class II substitutes must abide by the same reporting requirements
(see \'82.176 of the SNAP Final Rule).

The Agency recognizes that a substitute can potentially pass through
numerous steps prior to its introduction into interstate commerce.
Therefore, the Agency considers responsibility for notification under
SNAP to rest with the person who produces the substitute in its final
form for interstate commerce for purchase by an end-user. Under this
definition, the designated submitter could potentially be a
manufacturer, formulator, or an end-user.

a\. Chemical Manufacturers

Chemical manufacturers producing a substitute in its final form for
direct commercial sale to the end-user are required to notify the Agency
about the existence of that substitute. For instance, if a chemical
manufacturer intends to market a chemical as a substitute foam blowing
agent to companies that manufacture insulation products, the chemical
manufacturer would be required to notify the Agency about the existence
of the substitute. If the substitute is a new chemical, it must also
undergo simultaneous review under EPA\'s TSCA Premanufacture Notice
(PMN) program. For more information on this simultaneous review process,
see Section 2.C of this document.

b\. Formulators

A formulator is engaged in the preparation or formulation of a
substitute, after chemical manufacture of the substitute or its
components, for distribution or use in commerce. Formulators usually
only sell substitutes based on existing chemicals, since they do not
ordinarily possess chemical manufacturing capabilities. Chemicals used
in such substitutes are frequently in common use and have already been
approved for general use through other chemical review programs such as
TSCA or FIFRA.

However, these formulators can be considered directly responsible for
production of the substitute for an end-use. For example, by offering a
specific solvent formulation for an industrial cleaning process,
formulators would be subject to reporting requirements under SNAP. In
such cases, the formulator is best suited to present information on how
substitutes based on existing chemicals are or could be used. In cases
where the manufacturer of a chemical is also the formulator of a blend,
the manufacturer is responsible for meeting reporting requirements on
the substitute.

c\. End-users

In general, end-users of substitutes are not obligated to meet SNAP
reporting requirements, except in rare cases where the end-user is also
the substitutes=s producer that will be the first to introduce it into
commerce While the Agency expects that this situation will occur
infrequently, several large companies have developed substitutes for
their own use and subsequently have notified EPA of their intent to
offer those substitutes for commercial sale. Because EPA requires
end-users to report only on those substitutes they introduce into
interstate commerce, evaluating and listing such substitutes will not
stifle research and development innovations by end-users.

2\. Petitions

The SNAP program publishes lists of acceptable and unacceptable
substitutes. However, section 612(d) of the CAA explicitly states that
\"any person may petition the Administrator to add a substance \... or
to remove a substance from either of such lists.\" The petition
provision serves two principal needs. The first is to give the public a
way to appeal existing Agency determinations under the SNAP program. The
second is to provide a mechanism for individuals and organizations to
bring to the Agency\'s attention new information on substitutes that
could affect existing listing determinations or result in new ones.

The opportunity for outside parties to comment on existing listing
decisions is an important aspect of the petition process. As discussed
in the section on notifications, companies that produce substitutes must
submit specific data on the substitutes to the Agency for review.
However, organizations and private citizens other than those required to
submit SNAP notices may have additional information about existing
substitutes or information on new substitutes not yet reviewed by the
Agency. To ensure that the SNAP determinations are based on the best
information on substitutes, it is essential that the Agency offer a
means for such information to be incorporated into the SNAP analyses on
a continuing basis.

Before individuals, organizations, or companies may initiate legal
action against EPA for the purpose of changing the lists of acceptable
or unacceptable substitutes, they must first exhaust all administrative
remedies for receiving such relief, including remedies like the petition
process described in this section.

a\. Types of Petitions

Five types of petitions exist:

> \(1\) Petitions to add a substitute not previously reviewed under the
> SNAP program to the acceptable list;
>
> \(2\) Petitions to add a substitute not previously reviewed under the
> SNAP program to the unacceptable list;
>
> \(3\) Petitions to move a substitute from the acceptable list to the
> unacceptable list or to move a substitute from the unacceptable list
> to the acceptable list;
>
> \(4\) Petitions to add or delete use restrictions on an acceptability
> listing, and
>
> \(5\) Petitions to grandfather general use of a substitute found
> \"unacceptable\" or \"acceptable subject to narrowed use limits\" in
> specified applications within an end-use.

Petitioners should note that the first type of petition is comparable to
completing a SNAP submission, except that the latter is submitted by
substitute producers. The first type of petition, by contrast, would
generally be initiated by entities other than the company responsible
for producing the substitute. Companies that manufacture, formulate, or
use a substitute themselves and want to have their substitutes added to
the acceptable list should submit information on the substitute under
the 90-day advance notification review program.

> b\. Basis for Petition

A petitioner may submit a petition for several reasons, including:

> \$ Availability of new information on substitutes or end-uses not
> covered in the existing SNAP determinations;
>
> \$ Requests to extend the effective date for prohibitions on uses of
> an unacceptable substitute;
>
> \$ New technologies or practices that reduce exposure to a substitute
> previously unacceptable under SNAP due to toxicity or flammability
> concerns.

All of the above are examples of valid justifications for submitting a
petition. Other bases for petitioning the Agency may exist as well, and
all petitions with adequate supporting data will receive consideration
under the SNAP program.

> c\. Content of the Petition

Petition types (1) and (2) must contain the information requested in the
SNAP Information Notice. Information requirements for such petitions and
90-day notifications are the same, since the Agency will be applying the
same scrutiny to petitions submitted by outside parties as to
notifications received from the manufacturers themselves. For petition
types (3) and (4), which request a reexamination of a substitute
previously reviewed under the SNAP program, the submitter may reference
the prior submission rather than submit duplicate information. In this
case, the petitioner should specifically indicate any new or additional
data and submit complete test reports.

As described in the SNAP Final Rule, EPA must consider a specific test
to determine whether grandfathering should be allowed. This test
involves balancing the results of four analyses, including whether the
new rule represents an abrupt departure from previously established
practice, the extent to which a party relied on the previous rule, the
degree of burden which application of the new rule would impose on the
party, and the statutory interest in applying the new rule immediately.
Thus, petition type (5) requires information about the current level of
use of the substitute and other information to allow EPA to conduct
these analyses.

For all petitions, the Agency also requires the following information:

> \$ [Action requested]{.underline}: A brief statement describing the
> type of petition; and
>
> \$ [Rationale]{.underline}: A brief summary of the basis for the
> petition and the data that support the petition.
>
> d\. Nature of Response

EPA will only review and grant or deny petitions based on the sector and
end-use identified in the petition. For example, the fact that a
substitute is placed on the list of unacceptable substitutes for a
particular end-use in the solvents cleaning sector does not mean the
substitute is unacceptable for any specific end-use as a refrigerant. A
similar caveat applies for petitions on end-uses within a sector. If a
substitute, for instance, is found acceptable for a specific end-use
within a sector, it will not automatically be deemed acceptable for any
other end-use in that sector.

**E. When to Submit a SNAP Notice**

You must submit a SNAP notice at least 90 days before you begin sale of
a new substitute for an ozone-depleting substance. A petition may be
submitted any time adequate data exists for EPA consideration.

**F. Completing the Notice Form**

Please check the type of notice submitted on page 1 of the form. If this
notice is being submitted as part of a petition to the Agency, indicate
the type of petition. See Section 1.D for an explanation of the
different types of petitions.

**Part I - GENERAL INFORMATION**

You must complete all of Part I for your submission to be accepted for
review under SNAP. See below for sector-specific data requirements in
this section and others.

**Part I, Initial Information**

Please check the boxes on page 2 indicating the sector(s) for which you
are submitting information on the substitute and the types of test data
included in your submission. Attach all test data to the notice form and
reference them by page number in Part IV-List of Attachments (pg. 14).

**Part I, Section A - Submitter Identification (Page 3)**

1a. Person submitting notice - Enter information for the official who
signs the certification on page 15.

b\. Agent - Complete only if you authorize an agent to assist you in
preparing this notice. The agent must also sign the certification as
noted above.

c\. Joint Submitter - Identify the joint submitter, if any, who is
authorized by the primary submitter to provide some of the information
required in the notice. A notice will not be considered complete until
all information is received by the Agency. If information from multiple
parties will not be sent together, contact the SNAP Document Control
Officer (DCO) for information on submission tracking numbers to link
multiple notices.

> If you authorize another person (e.g. a foreign manufacturer or
> supplier) to provide information directly to EPA, indicate which
> information will be supplied by the other person. Identify that person
> by name, company, and address in a continuation sheet. Such a letter
> in support of your notice should be provided by the other person on
> company letterhead. An example of where this option could apply would
> be in situations where alternative formulation information is held
> confidentially by a foreign manufacturer. A notice will be considered
> incomplete until this information is provided. Whenever possible, use
> EPA\'s submission tracking number to link this information to your
> submission.

2\. Technical Contact - Identify a person who can provide EPA with
additional technical information on the substitute during the review
period. The technical contact identified should be located within the
U.S. and be available to be reached by telephone during normal business
hours.

3\. Provide information on any prior communication with EPA regarding
this submission. Provide the EPA staff person\'s name, the date, and the
form of communication (e.g. letter, phone). Mark the box in the lower
right if no prior communication has occurred.

**Part I, Section B - Alternative Identification (Page 4)**

EPA must receive a complete and unambiguous identification of the new
substitute. If the alternative is not adequately identified, we will
consider the submission incomplete, and the 90-day notice review period
will not begin. If you are an importer of an alternative and do not know
the chemical identity of a substitute, you must contact the foreign
manufacturer or supplier and have the specific chemical identity
provided directly to EPA. In this way, foreign manufacturers can protect
confidential business information. The same holds for U.S. manufacturers
reporting substitutes using a generic or trade name to identify a
component of the substitute. The submitter of the substitute must have
the supplier provide chemical information directly to EPA before the
notice can be considered complete. This information may be provided in a
letter of support on company letterhead from the supplier or in a joint
submission. Since a letter of support or a joint submission may be
received separately by the Agency, EPA\'s submission tracking number
should be used to link a submission or petition with information from a
supplier or foreign manufacturer to avoid delay in the review process.

1\. Commercial/Trade Name(s) of the Alternative - Indicate the name(s)
under which the alternative is marketed.

2\. Name of Chemical, Process, or Alternative Technology - Enter the
specific name of the chemical substance, the Chemical Abstracts Service
(CAS) registry number, and the molecular formula of the alternative. In
describing chemical substances, EPA prefers that International Union of
Pure and Applied Chemistry (IUPAC) nomenclature be used for
identification purposes. If the substitute is a blend of chemicals, you
must provide the exact composition and/or the range of percent
composition of all components (where appropriate) of a substitute. In
addition to active ingredients, you must also list other chemical
substances, such as solvents, inhibitors, etc., that may also be present
in the alternative.

> For alternative technologies and/or processes, provide a detailed
> description and diagram of the technology or process and information
> on [any]{.underline} chemical constituents.
>
> Also, if you have applied for or hold a patent on the substitute,
> provide the patent name and number. If you are waiting for a response
> to a patent application, indicate the date you submitted the
> application and the expected time for a response. Provide a copy of
> all patents that have already been granted on the substitute as an
> attachment.

Sector-Specific Data Requirements

> Solvents; Aerosols; Adhesives, Coatings, & Inks: Give the function of
> each constituent as well as the percent composition. For example, in
> an aerosol product, such a list may include:

HFC-134a (propellant)

dimethyl ether (propellant)

methanol (solvent)

silicone (active ingredient).

3\. Generic name - If the identity of a substitute is claimed as
confidential or if the formulation or process is such that it cannot be
identified by its individual chemical components, you must provide a
generic name that is only as generic as necessary to protect the
confidential identity. The name should reveal the chemical identity or
alternative process description to the maximum extent possible. The
generic name will be published in the Federal Register notice and
acceptability determination of the alternative. If the name seems more
generic than necessary, EPA will contact you and assist you in
developing an adequate name. EPA strongly prefers to avoid trade names
or marketing information in listing substitutes.

> EPA encourages you to contact the sector specialist to discuss the
> development of a generic name. This name should provide sufficient
> information for the public by indicating the classes of chemicals
> which the alternative contains without revealing specific information
> about the product\'s composition. For example, it may be necessary to
> reveal that a refrigerant blend contains an HCFC in order to allow
> users or importers to comply with regulations issued under sections
> 604or 608 of the CAA.
>
> When reviewing the SNAP lists for the solvents, aerosols, and
> adhesives, coatings and inks sectors you will notice that many of the
> listings are grouped into general classes of substitutes. If your
> substitute is already included under one of these classifications, you
> need to submit information to EPA for review under SNAP
> [only]{.underline} if your substitute contains a new chemical which is
> subject to review under the PMN program.

4\. Specific End-use - Identify the specific end-uses in which the
alternative is to be used. Be sure to provide a broad description (e.g.
terpene-based semi-aqueous solvent cleaner of metal parts as an
alternative for methyl chloroform, or HFC refrigerant as an alternative
for CFC-12 centrifugal chillers.) See Appendix A to this document for a
list of end uses in each industrial sector.

> Specify the ozone-depleting substance (ODS) being replaced, and
> include an estimate of the quantity of alternative (lbs.) needed to
> replace the ODS for each end-use. This is known as the replacement
> ratio. For example, if a solvent formulation contained 25% CFC-113 and
> now requires 50% petroleum distillate instead of CFC-113 to achieve
> similar performance, the replacement ratio is 2:1. Similarly, if 100
> pounds of a new refrigerant will replace 150 pounds of CFC-12, the
> replacement ratio is 1:1.5.
>
> See Appendix A for a list of end-uses included under SNAP. If you are
> proposing a new end-use, please indicate why the substitute does not
> fit into an existing one.

Sector-Specific Data Requirements

> Refrigerants: Indicate whether the alternative is a candidate for use
> in retrofits of existing equipment, for use in new equipment only, or
> both. If the alternative can be used both as a retrofit and in new
> equipment, these uses should be treated as separate end-uses
> throughout the notice. If the substitute is a chemical replacement,
> provide the size of the average charge used in each end-use. Describe
> the technolgy or the industry standard that will be used to recover
> the substitute.
>
> Foams: If the alternative blowing agent can be used in several
> different types of foam, treat each end-use separately throughout the
> notice.
>
> Fire Suppression: Provide information on the weight and storage volume
> equivalence replacement ratio for the substitute versus the ODS being
> replaced, using the method described in Appendix A.
>
> Tobacco Expansion: Specify the base replacement ratio values on the
> amount of new expansion agent consumed per unit mass of tobacco
> compared to the amount of CFC-11 consumed per unit mass.

5\. Impurities - Identify by name, weight percent, and CAS number (where
available) each impurity that you reasonably anticipate will be present
in the alternative as manufactured for commercial purposes. An impurity
is any chemical substance that is unintentionally present in the
alternative. List all impurities, regardless of weight percent. If the
substance contains some unidentified impurities, also enter
\"unidentified\". Do not include any substances that are mixed with the
new substance after manufacture of the primary ingredients. If there are
no impurities, enter \"None.\"

6\. Byproducts - Describe any byproducts or degradation products that
you reasonably anticipate will result from the manufacture, processing,
use, or disposal of the alternative both at sites you control and in
end-use. Identify these byproducts or degradation products by specific
name or class or range of structures (e.g., HF or other acid gases
formed from the combustion of halocarbon compounds), CAS Registry number
(where available), and the estimated amount formed. Also indicate where
the byproduct or degradation product is formed (e.g., during
manufacture, during end-use, following disposal).

Sector-Specific Data Requirements

> Foams: Provide information on the catalyst used in manufacture and an
> analysis of breakdown products under different external conditions,
> such as temperature, during use.
>
> Fire Suppression: Provide information on the degradation products of
> the alternative following discharge in a fire situation. Explain the
> conditions used in determining these products, such as the flame
> temperature, time required to extinguish the fire, amount of O~2~
> present, and the combustible material.

**Part II - ALTERNATIVE-SPECIFIC INFORMATION**

EPA requires certain information on all substitutes. However, the data
that are required may vary by sector. See Appendix B for more
information on sector-specific requirements.

**Part II, Section A - Physical and Chemical Properties (Page 6)**

Include all data on the physical or chemical properties of the
alternative that are reasonably available to you. Those properties
included in this section are illustrative and are not an exhaustive list
of potential data. See Appendix B for sector-specific data needs within
this section.

If you are extracting this information from a public reference source
(e.g., CRC Handbook of Chemistry and Physics, Merck Index), please
indicate the reference in Question 27, \"Other\". If you have performed
chemical analysis and testing on the substitute to derive the
properties, attach copies of all test reports and specify the protocol
used.

1-27. Complete the form as appropriate for the specific substitute. Many
physical characteristics will apply to more than one sector.

28\. Provide all test data regarding flammability of the substitute,
including the procedures used for determining flammability and any other
information on flammability concerns. If a substitute is flammable under
the proposed end-use conditions, describe any abatement techniques being
used to minimize the risks associated with use of a flammable substance.
EPA recognizes that many flammable alternatives may be promising.

> If an alternative is flammable (this applies to both blends and pure
> materials), you must analyze the risk of fire resulting from the use
> of the substitute in each proposed end-use. This assessment should
> include, but not be limited to, a description of typical scenarios in
> which the substitute is used, potential leak scenarios, sources of
> ignition, and probabilities of ignition. It should also assess the
> likelihood of injury within each scenario. Significant differences
> exist both in the design and in the ambient conditions for various
> end-uses. Thus, risk assessments are extremely sensitive to end-use.
> Low risk in one end-use does not, in general, imply low risk in
> another end-use. Describe measures taken to minimize any additional
> risk posed by the flammability of the alternative (e.g. equipment
> design modifications, alternative labeling).

Sector-Specific Data Requirements

> *Refrigerant alternatives*: Information on the flammability of a blend
> as well as its individual constituents must be provided. Testing of
> all blends should identify the compositions for which the blend itself
> is flammable. Blends that contain flammable components should be
> tested during leaks in system components containing two phases to
> identify limits of fractionation. In addition, non-azeotropic blends
> must be tested during normal operation. For substitutes that will be
> used in consumer applications, documentation of testing safety results
> conducted by independent laboratories should be submitted. Also
> include both evaporator and condenser temperature and pressure
> conditions. See Appendix B for suggested tests and examples of
> potential scenarios to be examined in a risk assessment.
>
> *Sterilants:* If the substitute is a blend with ethylene oxide (EtO),
> include information on the critical flammability ratios.
>
> *Aerosols*: If the product contains an immiscible component, address
> the potential flammability of the product that could be expelled if
> the entire mixture is not shaken immediately before each use.

**Part II, Section B - Atmospheric Information (Page 7)**

1\. Provide information on the predicted 100-year ozone depletion
potential (ODP) of the alternative relative to CFC-11, if known. If the
substitute is a blend, provide the ODPs of the individual constituents.
You should also provide supporting documentation indicating how and by
whom this value was calculated. This information may be provided as a
citation from the published literature or by providing the background
information used to develop the ODP.

> For purposes of calculating ODP, EPA recommends the methodology used
> in the [Scientific Assessment of Ozone Depletion: 2006]{.underline}
> (Chapter 8) prepared for the United Nations Environment Programme
> (UNEP) by the World Meteorological Organization (WMO). The ODP refers
> to the amount of ozone destroyed by a gas over its entire atmospheric
> lifetime (e.g. at a steady state) relative to that due to emissions of
> the same mass of CFC-11. It is defined in modeling calculations as
> follows:
>
> You should also include any other related data available to you, such
> as information on the substitute\'s atmospheric lifetime and chlorine
> or bromine loading potential. See the World Meteorological
> Organization 2006 document for additional information on calculating
> ODPs and related information. This document can be found online at
> http://ozone.unep.org/Assessment_Panels/SAP/Scientific_Assessment_2006/index.shtml.

2\. Provide information on the total global warming impacts (both direct
and indirect effects) of a substitute for each end-use. Direct effects
refer to the direct contribution to global warming from use of the
substitute due to its radiative forcing. Indirect effects are
contributions to global warming resulting from changes in energy
consumption and corresponding changes in emissions of CO~2~ and other
trace gases.

> Required information includes the 100-year global warming potentials
> (GWPs) of a substitute [relative to CO~2~]{.underline}. If they are
> available, you may also provide the 500- and 1000-year GWPs and the
> GWP relative to CFC-11, known as the halocarbon GWP (HGWP). If the
> substitute is a blend, provide the GWPs of the individual
> constituents. You should also include the data used to calculate these
> potentials such as atmospheric lifetime, infrared adsorption spectrum,
> and infrared absorption capacity. If known, provide information on the
> energy efficiency of the substitute relative to that of the substance
> being replaced and results of any testing or modeling done on the
> substitute. See Appendix B for a list of applicable tests. Data on
> energy efficiency is particularly of interest for alternative
> refrigerants and foam blowing agents.
>
> If the alternative is captured as a byproduct of another manufacturing
> or industrial process, indicate the source of the alternative. This
> information is important in assessing the effects of the new use of
> the substitute versus those effects occurring strictly because of the
> release of a byproduct.
>
> For purposes of calculating GWP, EPA recommends the methodology used
> by the Intergovernmental Panel for Climate Change (IPCC) in [Climate
> Change 2001: The Scientific Basis (Third Assessment
> Report)]{.underline} (2001)published by IPCC, the World Meteorological
> Organization (WMO), and United Nations Environment Programme (UNEP).
> You can obtain this document online at
> [http://www.grida.no/climate/ipcc_tar/.]{.underline} In this report,
> IPCC defines GWP of the emissions of a greenhouse gas as the time
> integrated commitment to climate forcing from the instantaneous
> release of 1 kg of a trace gas expresses relative to that from 1 kg of
> CO~2~.
>
> where:
>
> a~i~ = the instantaneous radiative forcing due to a unit increase in
> the concentration of trace gas, i
>
> c~i~ = the concentration of trace gas, i, remaining at time, t, after
> its release, and

n = the number of years over which the calculation is performed.

Corresponding values for CO~2~ are in the denominator.

**Part II, Section C - Other Statutes (Page 8)**

Please provide all information that is reasonably available regarding
regulation of a substitute under other regulatory authorities. The
Agency will evaluate substitutes under the SNAP program subject to
existing regulatory constraints. This information allows EPA to
coordinate regulatory efforts within EPA and among other authorities.

1\. Environmental Statutes - Provide information on whether the
substitute is regulated under any other environmental statutes such as:

> \$ other Titles of the Clean Air Act (CAA)
>
> \$ the Clean Water Act (CWA)
>
> \$ the Safe Drinking Water Act
>
> \$ the Resource Conservation and Recovery Act (RCRA)
>
> \$ the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)
>
> \$ the Toxic Substances Control Act (TSCA)
>
> \$ the Comprehensive Environmental Response, Compensation and
> Liability Act (CERCLA)
>
> \$ the Emergency Planning and Community Right-to Know Act (EPCRA or
> SARA Title III)
>
> \$ state and local laws
>
> List any concentration-based or other numerical standards to which the
> substitute is subject under the above statutes or regulations.
>
> For example, many alternative solvents are considered to be volatile
> organic compounds (VOCs) and are subject to emission restrictions
> under Title III of the CAA. If you know your alternative is either
> regulated or exempt as a VOC or Hazardous Air Pollutant (HAP), please
> indicate this.

2\. Other Statutes - Indicate whether the substitute is regulated under
other statutory authorities concerned with health and safety issues,
such as those implemented by:

\$ the Food and Drug Administration (FDA)

\$ the Occupational Safety and Health Administration (OSHA)

\$ the Department of Transportation (DOT)

\$ and state and local laws.

> Also include information on any other standard-setting bodies who will
> be evaluating the substitute, such as the National Fire Protection
> Association (NFPA) or the American Society of Heating, Refrigerating
> and Air Conditioning Engineers (ASHRAE). List any concentration-based
> or other numerical standards (e.g. permissible exposure limit (PEL),
> short-term exposure limit (STEL), safety classification) to which the
> substitute is subject under these statutes or organizations.

**Part II, Section D - Cost and Availability of the Alternative (Page
9)**

1\. Estimate the cost per pound (\$/lb) of the chemical substitute or,
where appropriate, indicate the cost per unit volume or per packaging
unit (e.g. aerosol spray can). If the cost is not per pound of material,
specify the units. For alternative processes and technologies, describe
the equipment costs and other costs such as those associated with
installing the new substitute.

2\. Provide information on the levels of production and market
penetration that you expect for the substitute. Include values for total
production in lbs/yr both at the start of production and in the future
(e.g., 3 years from now), the number of years you anticipate until the
substitute reaches its maximum market penetration, and the total
production level that you anticipate for the substitute when it reaches
the point of market saturation. Finally, estimate the percentage of the
market [held by the ODS being replaced]{.underline} that will be
captured by this substitute. If the substitute is not currently
available, indicate when you anticipate it will enter the marketplace.

> If you are submitting the substitute for several end-uses, you must
> provide this information for each end-use.

3\. Describe any new equipment and how the substitute or alternative
technology is used. If retrofitting of existing equipment is possible,
detail changes in technologies needed to use the substitute. Also
provide information on materials compatibility and attach any available
test results. Provide specific information on each different end-use,
including cost of equipment, equipment lifetime, changes in labor, and
changes in energy costs. For example, if the substitute is an
alternative refrigerant that may be used both as a retrofit or in new
equipment for chillers, information on the equipment changes should be
provided for both end-use scenarios. This cost information may be
provided as a range where equipment may be optimized to different levels
of energy efficiency.

> All claims that an agent is a \"drop-in\" for the ODS it is replacing
> must be substantiated, and qualified by a description of any necessary
> technical changes to existing equipment. Note, however, that not all
> sectors recognize drop-in replacements as a separate category.

**PART III - RELEASE AND EXPOSURE DATA**

The following sections describe the types of human health and safety and
environmental exposure data used to evaluate substitutes under the SNAP
program. For existing chemicals, specific data requirements may depend
on what types of data are already available. Attach all complete test
reports that are reasonably available to you. Also indicate all
concentration-based exposure limits that have been set for the
substitute, such as PELs, occupational exposure limits (OELs), or
acceptable exposure limits (AELs) set by the manufacturer. You may
submit references to studies that have already been submitted to the
SNAP program. If you have done a literature search on the alternative or
its constituents, please include it as well.

Decisions on data requirements will be determined by the exposure
patterns of the sector(s) in which the substitute is to be used. For
example, substitutes used only in settings which would generally
preclude all but acute exposures (such as in fire extinguishing) may not
require chronic toxicity data. For other sectors, such as solvent
cleaning, where aqueous solvents are used, additional tests may be
necessary depending on the means of discharge and disposal of the
substitute.

If the substitute is a blend containing constituents not previously
reviewed under SNAP for any end-use, additional data other than those
specified below may be required.

**Part III, Section A - Toxicity and Hazard Information (Page 10)**

1\. For chemical alternatives and for chemicals used with alternative
processes, summarize information on the acute and chronic toxicity of
the substitute and/or of its constituent chemicals on any organism (e.g.
humans, other mammals, fish, wildlife, plants, etc.). In addition to
those data mentioned specifically below, attach **all** supporting
information such as test reports, if available. In addition, attach a
copy of any hazard warning statement, label, material safety data sheet
(MSDS) or other information that will be provided to any person who is
reasonably likely to be exposed.

Sector-Specific Data Requirements

> *Refrigerants*: A cardiosensitization study, usually measuring
> cardiotoxic effects in the dog, is required. This requirement also
> applies to blends of chemicals which have already been tested
> individually. Blends can exhibit unpredictable cardiotoxicity levels,
> and testing is necessary.
>
> *Foams:* A study on the degradation products of the foam under
> different external conditions, including the catalyst used during
> manufacture and the temperature during use. EPA\'s assessment of
> potential hazards for insulation foam suggests that
> breakdown/degradation products of foam during use may be significant,
> and thus information on such processes is required.
>
> *Solvents:* To characterize aquatic toxicity, both acute and chronic
> toxicity data for a variety of species may be required. The Agency
> requires a minimum aquatic data set to be submitted as described in
> \"Guidelines for Deriving Numerical National Water Quality Criteria
> for the Protection of Aquatic Organisms and Their Uses,\" which is
> available through the National Technical Information Service (#PB
> 85-227049). If other regulatory limits such as effluent guidelines
> exist, these values may be used in lieu of compiling toxicity data.
>
> *Fire Suppression*: A cardiosensitization study, usually measuring
> cardiotoxic effects in the dog, is required. For specialized halon
> use, such as in airline cabins, information on central nervous system
> (CNS) depression may also be required. An exposure assessment, such as
> personal monitoring testing, for evaluation of alternative streaming
> agents may also be required.
>
> *Aerosols*: A cardiotoxicity study, usually measuring cardiotoxic
> effects in the dog, is required. Information on central nervous system
> (CNS) depression may also be required.
>
> *Adhesives, Coatings, & Inks*: Depending on the end-use, data
> requirements for this sector may be similar to the solvents and/or
> aerosols sector. Submit all relevant information, to the best of your
> knowledge.
>
> *Sterilants:* Concurrent review under FIFRA will cover toxicity issues
> and efficacy of such alternatives. The SNAP program does not require
> any additional toxicity testing of substitutes also reviewed under
> FIFRA. As stated above, attach copies of hazard warning statements,
> labels, and MSDSs that will be provided to any person likely to be
> exposed.

**Part III, Section B - Environmental Release and Disposal at
Manufacture (Page 10)**

Identify by name and address all manufacturing site(s) (within the U.S.
and worldwide) of each chemical or alternative technology. Also identify
all site locations for manufacturing of products containing the
substitute (e.g. refrigerators containing substitutes). If you are
unable to identify all manufacturing sites, provide data on a typical
facility. Identify all points of release and/or exposure during
manufacture of the substitute and any products containing the substitute
and the magnitude of the release. Also indicate the environmental media
to which it is released (e.g. indoor air, outdoor air, water, land).

**Part III, Section C - Occupational Exposure at Manufacture (Page 11)**

Provide information on occupational exposure during manufacture of the
substitute or alternative technology. This entry should include
information on exposure during manufacture of the substitute itself
and/or manufacture of products containing the substitute, where
appropriate (e.g. refrigerators containing the alternative). Describe
all activities in which workers may be exposed to the substitute,
estimate the levels of exposure, and describe any protective measures
taken to limit exposure.

**Part III, Section D - Environmental Release and Disposal in End-use
(Page 11)**

Provide information in this section as it applies to the sector(s) in
which the alternative will be used. For example, information applicable
to wastewater treatment should be included for solvent cleaning
alternatives but is not relevant to refrigeration substitutes. For each
substitute, indicate the quantities of the alternative that are released
directly to the environment and the environmental media to which it is
released (e.g. air, water, land).

Describe any control technologies used to limit emissions and indicate
the method and location of disposal and/or treatment of the substitute.
For example, explain if disposal will be performed on site, by a
contractor, by a vendor, or by other means. If the substitute is to be
recycled, describe any necessary equipment and programs that may be set
up to encourage recycling.

Identify the recovery technology that will be used to recapture the
substitute for disposal in specific end use sectors. Is current
technology available to recover the substitute? If yes, please describe
the technology by providing specifications or the specific industry
standard. However, if current recovery technology is not available
please describe how the substitute will be recovered again by providing
new equipment specifications, new industry standards or the new method.

**Part III, Section E - Occupational Exposure at End-use (Page 12)**

Provide information on occupational exposure during end-use (e.g.,
during use of an alternative solvent in an open-tank cleaning system).
Describe all activities in which workers may be exposed to the
substitute and estimate the levels of exposure. Also describe any
protective measures taken to limit exposure.

Sector-Specific Information

> *Fire Suppression*: Personal monitoring may be required for streaming
> agents, depending on the amount of agent required for fire suppression
> and the cardiotoxic level of the agent. For total flooding agents,
> indicate the extinguishing concentration using either a cup burner in
> heptane or full scale testing, and the design concentration of the
> substitute as defined by the National Fire Protection Association
> (NFPA) (cup burner plus 20 per cent). Indicate actual design
> concentration if it is likely to be higher, based on manufacturer
> recommendations.

**Part III, Section F - Consumer Exposure (Page 12)**

Provide information in this section as it applies to the sector(s) and
end-use(s) in which the substitute will be used. If the alternative is
intended for industrial use only (e.g. a refrigerant for cold storage
warehouses) you need not provide information in this section.

**Part III, Section G - General Population Exposure - OPTIONAL (Page
13)**

EPA has performed risk screens on alternatives to ozone-depleting
substances which indicate that risks to the general population during
manufacture of these substitutes are lower, on an overall basis, than
risks of continued reliance on ODSs. You do not need to provide the
information requested in this section unless you choose to do so.

**Part IV - LIST OF ATTACHMENTS (Page 14)**

Attach any continuation sheets for sections of the form, test data, and
other data that may assist EPA review of an alternative after the last
page of the form. Clearly identify the attachment and the section to
which it relates on page 14, where appropriate. Number consecutively the
pages of each attachment and enter the inclusive page numbers on page
14. Enter the total number of pages in the notice, including
attachments, on page 1 of the form.

Mark (X) the confidential box next to any attachment name that you claim
as confidential. See Chapter **[I.B]{.underline}** of this manual for
information on how to claim any information in an attachment as
confidential.

**Part V - CERTIFICATION (Page 15)**

The official named in Part I, Section A of the form as the person
submitting the notice must sign the certification on page 15 of the
notice form. This official is responsible for the truth and accuracy of
each statement in the certification. If an agent assists you in
preparing the notice, the agent must also sign the certification. All
signatures must be original. [If the submission is not signed, EPA will
consider the submission incomplete and will not review the
substitute.]{.underline}

**2. SUPPLEMENTARY INFORMATION**

**A. Substitutes That Must Be Reported by Designated Submitters**

Based on the language of section 612(a) of the CAA, EPA defines a
\"substitute\" as any chemical, product substitute, or alternative
manufacturing process that could replace a class I or class II
substance. Section 612(e) makes clear that substitutes include both
existing and new chemicals and technologies. Also, the language in
section 612(c) clearly states that a new substitute may be currently or
potentially available. EPA defines \"potentially available\" as
indicating any alternative for which adequate information exists to make
a determination under SNAP, and one the Agency reasonably believes to be
technically feasible, even if all testing has not yet been completed and
the alternative is not yet produced and sold.

EPA believes that the statutory language included in section 612 is
written broadly to allow for an all-encompassing evaluation of
substitutes that will be introduced as replacements for ozone-depleting
chemicals. However, clarification is presented below to explain the
Agency\'s definition of a \"substitute\" in specific circumstances based
on section 612.

1\. [Chemicals Already Listed as \"Existing\" under TSCA]{.underline}

SNAP review is critical for such chemicals, given the differing
statutory objectives of TSCA and the CAA.

2\. [Significant New Use of Existing Alternatives]{.underline}

Existing alternatives already being sold commercially within a SNAP
sector (e.g., use of semi-aqueous cleaners in the electronics industry)
are subject to review under SNAP.

3\. [Class I and Class II Chemicals as Substitutes]{.underline}

Class I and class II chemicals used as substitutes will continue to
deplete stratospheric ozone and, thus, a SNAP review of these
alternatives is necessary.

> 4\. [Substitutes for Class II Compounds]{.underline}

The same information reporting requirements and listing process apply to
substitutes for class II compounds as for substitutes for class I
compounds.

**B. Substitutes Excluded From Notification Requirements**

The Agency has identified several situations in which notification to
the SNAP program is not required. These exemptions from reporting are
discussed below.

> 1\. [Substitutes Already Listed Under SNAP]{.underline}

Lists of substitutes are available from EPA Air Docket A-91-42, online
at http://www.epa.gov/ozone/snap/lists/index.html, and from the
Stratospheric Protection Hotline at (800) 296-1996.

2\. [Small Sectors]{.underline}

The major industrial use sectors included under SNAP are: refrigeration;
foam blowing; fire suppression and explosion protection; solvent
cleaning; adhesives, coatings, and inks; aerosols; sterilization; and
tobacco expansion. If an ozone-depleting compound is not being used
under one of these sectors, substitutes need not be submitted under
SNAP. Please submit information to EPA if you identify another large
industrial use sector.

3\. [Small Volume Use within SNAP Sectors]{.underline}

Producers of substitutes for ozone-depleting compounds in annual
quantities of 10,000 lbs per year or less for an end-use within a sector
do not need to notify EPA of their activities under SNAP. However, EPA
encourages producers to maintain documentation describing the basis for
their view that any substitute being used meets this small use
definition. This documentation could be necessary in the event the
Agency receives a petition to evaluate such substitutes. Documentation
should take the form of production volume and sales information which is
typically maintained by many producers irrespective of any regulatory
requirements.

> 4\. [Second-Generation Substitutes]{.underline}

EPA believes that as long as class I or class II chemicals are being
used, any substitute designed to replace these chemicals is subject to
review under section 612.

> 5\. [Formulation Changes]{.underline}

In general, formulation changes that accommodate replacement of class I
and class II compounds are not subject to the provisions of section 612.
Such changes may be necessary, for example, when a new foam blowing
agent necessitates the replacement of the catalyst formerly used with
the class I blowing agent. However, if a SNAP submitter has reason to
believe such changes will significantly influence the environmental and
human health risk characteristics associated with the use of any class I
or class II substitute, this concern should be communicated to the
Agency. EPA may also review any changes in formulation in connection
with review of substitute compounds where the Agency has reason to
believe the formulation change may affect the risk profile of a
substitute.

> 6\. [Test Marketing]{.underline}

Use of alternatives for the sole purpose of test marketing is exempt
from any reporting requirements under section 612. However, once you
decide to sell an alternative as a class I or class II substitute, you
must provide the Agency with notification at least 90 days prior to
commercialization. Producers of new chemicals must still abide by the
provisions of section 5(h)(1) of TSCA, which authorizes EPA to grant
exemptions from TSCA-reporting requirements, provided that test
marketing will not present an unreasonable risk to human health or the
environment. When submitting the TSCA application, you are encouraged to
notify EPA\'s Office of Air and Radiation; however, such notification is
not required under SNAP.

> 7\. [Research & Development]{.underline}

Substitutes manufactured or imported solely for research and development
are exempt from reporting requirements under section 612. Amounts used
in research are assumed to be the minimum necessary for reasonable
scientific experimentation. For new chemicals, the provisions of
\'720.36 of the PMN rule (40 CFR Part 720) are in effect.

> 8\. [Substitutes Produced for Export]{.underline}

In the final SNAP rule, substitutes that are produced solely for export
and use by non-U.S. entities outside the U.S. were exempted from
reporting requirements under SNAP. However, recent legal actions are
pending resolution. Please contact the SNAP coordinator for the latest
information on this topic.

> 9\. [Substitutes Used as Feedstock]{.underline}

Substitutes that could replace class I chemicals which are used solely
as intermediates in the production of other chemicals are exempt from
reporting to the SNAP program.

**C. Joint Review with Other EPA Offices**

1\. [Overlap with the TSCA PMN Program]{.underline}

New chemical substitutes must undergo review both under section 612 and
section 5 of TSCA (the Premanufacture Notice program). Because of the
overlap in statutory authority, the Agency has established a joint
review process between the SNAP and TSCA Premanufacture Notice (PMN)
programs. This process has been structured to minimize reporting burden
and to ensure consistency in decisions between the two programs. The
following sections describe the joint review and decision-making process
in more detail.

a\. [SNAP and PMN Forms]{.underline}

In general, the Agency has identified only a few additional data
elements that are not required by TSCA but are needed for SNAP review:

> \$ Ozone depletion potential
>
> \$ Global warming potential
>
> \$ Cost of using the substitute
>
> \$ Flammability testing results

Given this overlap, a submitter requesting review under both the SNAP
and PMN programs should:

> \$ Complete the PMN form (EPA Form 7710-25) following the Instructions
> Manual available through the TSCA Assistance Information Service.
>
> \$ Indicate on page 11 of the PMN form, \"Optional Pollution
> Prevention Information,\" that the chemical is also to be considered
> under the SNAP program.
>
> \$ Complete a SNAP TSCA addendum form, available from the SNAP
> document control officer.

The completed PMN form (EPA Form 7710-25) will remain the basis for all
information needed to complete review of the new chemical under section
5 of TSCA. The completed PMN form and the SNAP addendum together will
comprise the data submission for section 612 review and listing
decisions for new chemicals. This approach is intended to minimize your
reporting burden.

The Agency has modified the PMN Instructions Manual to provide you with
more explicit direction on how to complete the SNAP addendum. Any
questions regarding the completion of these forms can be directed to
either the PMN pre-notice coordinator or the SNAP DCO.

b\. [Submission of Completed Forms]{.underline}

Both the PMN and SNAP programs have a review period of 90 days, subject
to suspensions and extensions described in \'82.180 for the SNAP program
and in the PMN rule (40 CFR 720.75). To ensure that new chemical
submissions are reviewed and decided on jointly, you are encouraged to
provide both the PMN form and SNAP addendum to both programs. Failure to
provide this information to both programs at the same time could result
in delays in the review of your notice.

c\. [Procedures for Handling Confidential Business
Information]{.underline}

EPA recognizes that information submitted to the PMN and SNAP programs
may need to be held confidential. All CBI submitted as part of the joint
PMN/SNAP review will be maintained and treated in a manner consistent
with TSCA security procedures. Confidentiality claims will be processed
and reviewed in a manner consistent with 40 CFR Part 2, Subpart B.
Please note that while TSCA and CAA may have different language
describing CBI handling procedures, there is no substantive difference
in how CBI is maintained under the two statutes.

2\. [Overlap with the FIFRA Program]{.underline}

Any new pesticide or amendment of an existing formulation is already
subject to Agency approval under provisions of the Federal Insecticide,
Fungicide and Rodenticide Act (FIFRA), P.L. 100-460, 100-464 to 100-526,
and 100-532. In addition, as of April 18, 1994, new pesticides or
formulation changes based on class I or class II substitutes will also
be subject to review under section 612 of the CAA. These authorities
apply in all cases where a manufacturer reformulates a pesticide product
to replace class I or class II chemicals. Similarly, registrations of
new pesticide products will also be subject to SNAP review if the new
product contains chemicals functionally replacing class I or II
compounds which would otherwise have been used in the new pesticide
formulation.

a\. [Review Responsibilities Under FIFRA and CAA/SNAP]{.underline}

In general, review responsibilities for pesticide products under the
SNAP program will focus on a substance\'s ozone depletion and global
warming potentials. FIFRA reviews will address factors commonly examined
during pesticide amendments and registrations. The two program offices
responsible for these reviews will coordinate their efforts and share
pertinent data to ensure appropriate technical consideration of the
substitute.

b\. [Data Submission Requirements and Process]{.underline}

The Agency has found no significant overlap between FIFRA and SNAP
review. Because there is so little overlap, a submitter requesting
review under both programs must submit all information ordinarily
required for the OPP process as well as a completed SNAP Information
Form. A copy of the FIFRA form should be submitted to OPP, and a copy of
the SNAP form should be submitted to the SNAP DCO.

If you are submitting an amendment to a product registration under FIFRA
that currently contains a class I or II substance, you should note in
Section II (\"Amendment Information\") of the FIFRA form that the
amendment was filed in response to the CAA production phase-out.
Similarly, if you are submitting an application for a new pesticide
registration that would otherwise have been based on a class I or II
compound, you should note in Section II of the FIFRA form that the
registration includes a class I or II substitute. You should also
identify both the substitute chemical and the class I or II compound it
is replacing. Further, if you are aware that a particular chemical
intended for use as a class I or class II substitute in a pesticide
formulation has already been approved through earlier SNAP/FIFRA
determinations, you should also reference the relevant part of the prior
review.

**D. Consultation with EPA Concerning the SNAP Information Notice**

1\. [Contact Prior to Notice Submission]{.underline}

Copies of the SNAP rule, listing decisions, this Guidance Document, the
SNAP Information form, and other materials relating to the rule are
available online on EPA=s SNAP web page
([http://www.epa.gov/ozone/snap/index.html) and]{.underline} through the
Stratospheric Protection Hotline at (800) 296-1996. These materials are
also available through EPA regional offices. You may contact the
Stratospheric Protection Division of EPA in Washington, DC at (202)
343-9410. Written inquiries may be sent to:

SNAP Coordinator

U.S. EPA

Mail Code 6205J

1200 Pennsylvania Ave. NW

Washington, DC 20460

2\. [Contact During Notice Review]{.underline}

The 90-day notice review period begins when your notice is determined to
be complete by the SNAP Document Control Officer (DCO). You will receive
written notification within 15 days of receipt by EPA if your notice is
declared \"incomplete\" as described in \'82.180. If your notice is
complete, you will receive an acknowledgment letter confirming the date
EPA received your notification and the date EPA\'s 90-day review period
begins. The letter will also include the document tracking number
assigned to your submission. If your alternative has already been listed
under the SNAP program for the proposed end-use, you will be notified
that your substitute is not subject to SNAP review, and therefore you
are free to begin manufacture immediately.

The appropriate SNAP sector specialist will contact you if the review
period on the alternative will be extended under \'82.180. However,
following expiration of the initial 90-day review period, you are free
to begin manufacturing your product for commercial sale, provided that
EPA has not already listed the alternative as unacceptable through
notice-and-comment rulemaking.

Review of petitions will occur by the same process and schedule as
submissions from manufacturers of new substitutes.

Formula for determining Weight and Volume Equivalence:

> NOTE: Weight and volume equivalents are calculated using a single,
> fuel-specific design concentration (heptane); therefore, they do not
> represent the exact weight or volume of the agent needed to protect
> any specific space against any specific hazard. The information used
> to calculate the equivalents is provided from agent manufacturers and
> NFPA 2001, \"Standard on Clean Agent Fire Extinguishing Systems.\"
> Equivalents are included in SNAP rulemakings for general comparison
> and informational purposes only.
>
> EPA understands that fire suppression agents must be evaluated in the
> context of the fire extinguishing system equipment with which they are
> used. Design concentration, and weight and volume equivalents are only
> meaningful when evaluated in specific system hardware configurations.
> This is especially important when comparing storage volume where
> storage container fill density varies with the equipment used. Agent
> fire suppression performance will vary with the system used and the
> detailed design of the system. Therefore, fire suppression agent
> manufacturers do not generally recommend design concentrations as
> these are also a function of the system hardware in which they are
> used. Hence, these data are provided for general guidance only and do
> not reflect a recommendation for system design or a basis for rigorous
> quantitative comparison.

\(1\) Weight and volume equivalent data should be presented relative to
Halon 1301 at 120 per cent of cup burner as well as at 5 per cent, a
typical use concentration;

\(2\) weight and volume equivalents should be based on agent
concentrations at Standard Temperature and Pressure;

\(3\) weight and volume equivalents should be done at both the
manufacturer\'s recommended design concentration and at 120 per cent of
the cup burner value where the values are not the same;

\(4\) volume equivalents will be based on agent volume only (exclusive
of container volume, fill density, etc.) at 70 degrees Fahrenheit and
the storage pressure specified by the manufacturer since this varies
widely and the required agent mass determined in item (5) below; and

\(5\) the required agent weight equivalents should be determined by the
following equation:

W = V/S(C/100-C)

where C = design concentration (% volume)

V = one cubic foot

S = agent specific vapor volume at 70 degrees F (ft^3^/lb).

\(6\) Appropriate references to the technical literature on which the
data are based should be provided.
