Perfluoroalkyl Sulfonates; Proposed Significant New Use Rule

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: EPA is proposing to amend a significant new use rule (SNUR)
under section 5(a)(2) of the Toxic Substances Control Act (TSCA) to
include certain perfluoroalkyl sulfonates (PFAS) substances. EPA is
proposing to amend the PFAS SNUR at 40 CFR 721.9582 by adding a new
Table 3 containing the remaining PFAS chemicals on the TSCA Inventory
that are not already regulated by the SNUR. This proposed rule would
require manufacturers, including importers, to notify EPA at least 90
days before commencing the manufacture or import of the PFAS chemicals
listed in Table 3 of the regulatory text proposed herein for the
significant new uses described in this document on or after April 10,
2006. EPA believes that this action is necessary because these chemical
substances may be hazardous to human health and the environment. The
required notice will provide EPA the opportunity to evaluate intended
significant new uses and associated activities before they occur and,
if necessary, to prohibit or limit those uses or activities.

DATES: Comments must be received on or before April 10, 2006.

SUPPLEMENTARY INFORMATION:

I. General Information

A. Does this Action Apply to Me?

    You may be potentially affected by this action if you manufacture
(defined by statute to include import) any of the chemical substances
that are listed in Table 3 in Sec.  721.9582(a)(1) of the proposed
regulatory text.
    Persons who intend to import any chemical substance governed by a
final SNUR are subject to the TSCA section 13 (15 U.S.C. 2612) import
certification requirements, and to the regulations codified at 19 CFR
12.118 through 12.127 and 127.28. Those persons must certify that they
are in compliance with the SNUR requirements. The EPA policy in support
of import certification appears at 40 CFR part 707, subpart B. In
addition, any persons who export or intend to export a chemical
substance

that is the subject of this proposed rule on or after April 10, 2006
are subject to the export notification provisions of TSCA section 12(b)
(15 U.S.C. 2611(b)) (see 40 CFR 721.20), and must comply with the
export notification requirements in 40 CFR part 707, subpart D.
Potentially affected entities may include, but are not limited to:
     Manufacturers (defined by statute to include importers) of
one or more of the subject chemical substances (NAICS 325 and 324110),
e.g., chemical manufacturing and petroleum refineries.
    This listing is not intended to be exhaustive, but rather provides
a guide for readers regarding entities likely to be affected by this
action. Other types of entities not listed in this unit could also be
affected. The North American Industrial Classification System (NAICS)
codes have been provided to assist you and others in determining
whether this action might apply to certain entities. To determine
whether you or your business may be affected by this action, you should
carefully examine the applicability provisions in 40 CFR 721.5 and 40
CFR 721.9582 as proposed herein. Also consult Unit II. If you have any
questions regarding the applicability of this action to a particular
entity, consult the technical person listed under FOR FURTHER
INFORMATION CONTACT.

B. What Should I Consider as I Prepare My Comments for EPA?

    1. Submitting CBI. Do not submit this information to EPA through
regulations.gov or e-mail. Clearly mark the part or all of the
information that you claim to be CBI. For CBI information in a disk or
CD ROM that you mail to EPA, mark the outside of the disk or CD ROM as
CBI and then identify electronically within the disk or CD ROM the
specific information that is claimed as CBI. In addition to one
complete version of the comment that includes information claimed as
CBI, a copy of the comment that does not contain the information
claimed as CBI must be submitted for inclusion in the public docket.
Information so marked will not be disclosed except in accordance with
procedures set forth in 40 CFR part 2.
    2. Tips for preparing your comments. When submitting comments,
remember to:
    i. Identify the document by docket number and other identifying
information (subject heading, Federal Register date, and page number).
    ii. Follow directions. The Agency may ask you to respond to
specific questions or organize comments by referencing a Code of
Federal Regulations (CFR) part or section number.
    iii. Explain why you agree or disagree; suggest alternatives and
substitute language for your requested changes.
    iv. Describe any assumptions and provide any technical information
and/or data that you used.
    v. If you estimate potential costs or burdens, explain how you
arrived at the estimate.
    vi. Provide specific examples to illustrate your concerns and
suggested alternatives.
    vii. Explain your views as clearly as possible, avoiding the use of
profanity or personal threats.
    viii. Make sure to submit your comments by the comment period
deadline identified.

II. Background

A. What Action is the Agency Taking?

    On October 18, 2000, EPA published in the Federal Register a
proposed SNUR (65 FR 62319) (FRL-6745-5) (Ref. 1) to regulate the
chemicals referred to as perfluorooctyl sulfonates (PFOS). The
structure and definition of those chemicals affected by the proposed
SNUR were described on page 62325, Unit IV.A. of that proposed rule.
The corresponding final rule was published in the Federal Register on
March 11, 2002 (67 FR 11008) (FRL-6823-6), for 13 perfluoroalkyl
sulfonates (PFAS) chemicals (Ref. 2). In response to comments, EPA
agreed to use the generic term perfluoroalkyl sulfonates (PFAS) to
encompass more generally this category of perfluorinated compounds,
which includes those with eight carbons (C8) as well as those with
higher and lower amounts of carbon. The Agency also agreed to use the
term PFOS to represent only those chemical substances that are
predominantly C8. A supplemental proposed SNUR for 75 other similar
PFAS chemicals was published in the Federal Register on March 11, 2002
(67 FR 11014) (FRL-6823-7) (Ref. 3). EPA promulgated a final rule for
these 75 PFAS chemicals on December 9, 2002 (67 FR 72854) (FRL-7279-1)
(Ref. 4). As used in this proposal, the term PFAS refers to a general
category of perfluorinated sulfonate compounds and includes compounds
of carbon chain lengths greater than four. The term PFOS refers to a
subcategory of PFAS compounds that have an eight-carbon chain length.
    EPA believed that those actions were necessary because data showed
that certain alkyl chain lengths of the PFAS chemicals are toxic to
human health, bioaccumulate, and are persistent in the environment. The
December 9, 2002 final rule designated manufacture and import for any
use of the specific PFAS chemicals listed in Tables 1 and 2 of 40 CFR
721.9582 as significant new uses with the following four exceptions for
chemical substances in Table 2:
     Use as an anti-erosion additive in fire-resistant
phosphate ester aviation hydraulic fluids.
     Use as a component of a photoresist substance, including a
photo acid generator or surfactant, or as a component of an anti-
reflective coating, used in a photomicrolithography process to produce
semiconductors or similar components of electronic or other
miniaturized devices.
     Use in coatings for surface tension, static discharge, and
adhesion control for analog and digital imaging films, papers, and
printing plates, or as a surfactant in mixtures used to process imaging
films.
     Use as an intermediate only to produce other chemical
substances to be used solely for the uses listed in exceptions 1
through 3.
    EPA is proposing to add 183 PFAS chemicals to the SNUR at 40 CFR
721.9582. The 183 chemicals are listed in Table 3 which appears in the
proposed regulatory text. EPA believes that this action is warranted
given the similarity of these chemicals to those currently included in
40 CFR 721.9582 and the strong likelihood of similar health and
environmental concerns, as discussed in Unit III.A. Specifically, the
Agency is proposing to designate as a ``significant new use'' the
manufacture, including import, for any use of the chemical substances
listed in Table 3 of the proposed regulatory text; however, the Agency
is also proposing to make the excepted uses described in 40 CFR
721.9582(a)(3) applicable to the chemicals listed in Table 3 of the
proposed regulatory text. The listed chemical substances in Table 3 are
on the TSCA Inventory and have carbon chains greater than, or equal to,
C5 with the PFAS chemical structure. This action also includes those
chemicals with ranges of carbon chains shorter than C5 but that extend
beyond C5, for example, C4-C12. EPA specifically solicits comment on
whether there is any ongoing manufacture or import of the chemicals
subject to this proposed rule as well as information on any uses of
such chemicals.
    This proposed rule would require persons to notify EPA at least 90
days before commencing the manufacture (including import) of the
chemical substances identified in Table 3 of the proposed regulatory
text for the following significant new uses:

     The manufacture, including import, for any use of any of
the chemicals listed in Table 3 of the proposed regulatory text.
     However, the manufacture or import of any chemical listed
in Table 3 of the proposed regulatory text for one or more of the
following specific uses shall not be considered as a significant new
use subject to reporting:
    1. Use as an anti-erosion additive in fire-resistant phosphate
ester aviation hydraulic fluids.
    2. Use as a component of a photoresist substance, including a photo
acid generator or surfactant, or as a component of an anti-reflective
coating, used in a photomicrolithography process to produce
semiconductors or similar components of electronic or other
miniaturized devices.
    3. Use in coating for surface tension, static discharge, and
adhesion control for analog and digital imaging films, papers, and
printing plates, or as a surfactant in mixtures used to process imaging
films.
    4. Use as an intermediate only to produce other chemical substances
to be used solely for the uses listed in 1., 2., or 3.
    EPA is proposing to extend the exceptions to these chemicals due to
the possibility that their use profiles are similar to those already
covered in the SNUR. EPA is soliciting comment on whether the excepted
uses are still necessary for the chemicals listed in Table 3 of the
proposed regulatory text and depending on comments received may decide
not to extend the exceptions in some or all cases. The original
exceptions were granted based on limited volume of the uses, the extent
of controls on exposure and releases, and the absence of viable
alternatives.

B. What is the Agency's Authority for Taking this Action?

    Section 5(a)(2) of TSCA (15 U.S.C. 2604(a)(2)) authorizes EPA to
determine that a use of a chemical substance is a ``significant new
use.'' EPA must make this determination by promulgating a rule after
considering all relevant factors, including those listed in TSCA
section 5(a)(2). These factors include the projected production volume
of a chemical substance; the extent to which a use changes or increases
the type, form, magnitude, or duration of exposure to the substance;
and the reasonably anticipated manner of producing, processing,
distributing, or disposing of the substance. EPA construes the statute
to allow consideration of any other relevant factors, in addition to
those listed in section 5(a)(2). Once EPA determines that a use of a
chemical substance is a significant new use, and promulgates a SNUR,
section 5(a)(1)(B) of TSCA requires persons to submit a Significant New
Use Notice (SNUN) to EPA at least 90 days before they manufacture,
import, or process the chemical substance for that use.

C. Applicability of General Provisions

    General regulatory provisions for SNURs appear in 40 CFR part 721,
subpart A. These provisions describe persons subject to the rule,
recordkeeping requirements, and exemptions to reporting requirements.
Provisions relating to user fees appear at 40 CFR part 700. Persons
subject to the final SNUR must comply with many of the same notice
requirements and EPA regulatory procedures as submitters of
premanufacture notices (PMNs) under section 5(a)(1)(A) of TSCA. Those
requirements include the information submission requirements of TSCA
section 5(b) and 5(d)(1), the exemptions authorized by TSCA section
5(h)(1), (2), (3), and (5), and the regulations at 40 CFR part 720 (see
40 CFR 721.1(c)). Receipt of a SNUN by EPA may trigger regulatory
action under TSCA sections 5(e), 5(f), 6, or 7, if appropriate, to
control the activities described in the SNUN. If EPA does not take
action after receipt of a SNUN, EPA is required under TSCA section 5(g)
to explain in the Federal Register its reasons for not taking action.
    Persons who intend to export a substance identified in a proposed
or final SNUR are subject to the export notification provisions of TSCA
section 12(b). The regulations that implement TSCA section 12(b) appear
at 40 CFR part 707, subpart D. Persons who intend to import a chemical
substance identified in a final SNUR are subject to the TSCA section 13
import certification requirements, which are codified at 19 CFR 12.118
through 12.127 and 127.28. Such persons must certify that they are in
compliance with TSCA sections 5, 6, and 7 requirements. The EPA policy
on import certification appears at 40 CFR part 707, subpart B.

III. Rationale for this Proposed Rule

A. What are the Environmental Characteristics of PFAS?

    All of the chemical substances in Table 3 of the proposed
regulatory text are referred to collectively in this proposed rule as
perfluoroalkyl sulfonates, or PFAS. There is evidence that PFAS
chemicals degrade back to perfluoroalkylsulfonic acid (PFASA), which
exists in the anionic form in the environment, or to PFASA precursors.
Further degradation of PFASA is not observed under normal environmental
conditions. In fact, PFASA is highly persistent in the environment and
has a tendency to bioaccumulate (Refs. 6 and 7). PFASA can continue to
be formed by any PFAS containing chemicals introduced into the
environment.
    Studies have found PFAS chemicals containing five to fourteen
carbons (C5-C14) in very small quantities in the blood of the general
human population as well as in wildlife, indicating that exposure to
the chemicals is widespread (Refs. 6, 7, and 8).
    Biological sampling has discovered the presence of certain
perfluoroalkyl compounds in fish and in fish-eating birds across the
United States and in locations in Canada, Sweden, and the South Pacific
(Ref. 6). The wide distribution of the chemicals in high trophic levels
is strongly suggestive of the potential for bioaccumulation and/or
bioconcentration.
    Based on currently available information, EPA believes that while
all PFAS chemicals are expected to persist, the length of the
perfluorinated chain may also have an effect on bioaccumulation and
toxicity, which are also characteristics of concern for these
chemicals. PFAS chemicals with longer carbon chain lengths may be of
greater concern than those with shorter chain lengths (Refs. 9, 10, and
11).

B. What are the Health Effects of PFAS?

    The hazard assessment published by the Organization for Economic
Cooperation and Development (OECD) (Ref. 15) concluded that PFOS is
persistent, bioaccumulative and toxic to mammalian species. While most
studies to date have focused primarily on PFOS (with eight carbons
(C8)), structure-activity relationship analysis indicates that the
results of those studies are applicable to the category of PFAS
chemicals, which includes PFOS. Available test data have raised
concerns about their potential developmental, reproductive, and
systemic toxicity (Refs. 6, 7, and 8).
    Toxicology studies show that PFOS, as measured in its anionic form,
is well absorbed orally and distributes primarily to the serum and
liver. It does not appear to be further metabolized. Elimination from
the body is slow and occurs via both urine and feces. Serum PFOS levels
in three retired male 3M Company chemical workers have been tracked and
suggest a mean elimination half-life in humans of approximately 4 years
(Ref. 8). Epidemiologic studies have shown an association between PFOS
exposure and the incidence of

bladder cancer, although further work is needed (Ref. 15).
    Studies on PFOS generally indicate moderate toxicity to
environmental species (fish, aquatic plants and invertebrates,
amphibians and birds), although in the case of honey bees, high
toxicity was observed (Ref. 15).

C. What are the Uses and Production Levels of these Chemicals?

    The Agency believes that the 183 PFAS chemicals included in this
proposal are no longer being manufactured for any uses in the United
States, except possibly for excepted uses under 40 CFR 721.9582(a)(3).
As mentioned in Unit II.A., EPA is soliciting comment on the need for
the excepted uses for the chemicals listed in Table 3 of the proposed
regulatory text. 3M Company, the principal domestic manufacturer of
PFAS chemicals, has publicly committed to using perfluorobutane
sulfonate (PFBS) (a four carbon (C4) based PFAS) instead of PFOS or
other PFAS chemicals in its products (Ref. 5). The Agency has no
indication that the PFAS chemicals covered by this proposal are in
commercial production for any use; however, there could be instances
where these chemicals are produced in amounts that fall below any
reporting thresholds, e.g., under the Inventory Update Rule at 40 CFR
part 710, and therefore EPA would be unaware of their production.
    PFOS and related sulfonyl-based fluorochemicals, which are a subset
of the overall PFAS category of chemicals and are included in 40 CFR
721.9582, were used in a variety of products, which can be divided into
three main use categories: surface treatments, paper protection, and
performance chemicals (Ref. 12). In the past, PFAS chemicals in the
performance chemicals category were used in a wide variety of
specialized industrial, commercial, and consumer applications. Specific
applications included fire fighting foams, mining and oil well
surfactants, acid mist suppressants for metal plating and electronic
etching baths, alkaline cleaners, floor polishes, inks, photographic
film, denture cleaners, shampoos, chemical intermediates, coating
additives, carpet spot cleaners, and as an insecticide in bait stations
for ants (Ref. 12). In 2000, the domestic production volume of the PFAS
chemicals containing eight carbons (C8) for the performance chemicals
use category was estimated to be approximately 1.5 million pounds (Ref.
13).
    The 3M Company discontinued manufacture of some specific PFAS and
related chemicals as of 2002. The Agency is aware that PFAS and PFAS-
related chemicals have been produced by and/or imported from companies
located in countries outside of the United States, including Italy,
Belgium, Germany, Norway, Poland, and Switzerland, among others, and
that many other companies have sold PFAS-related products (Ref. 14).
The Agency is not aware of any uses or imports in the United States of
the remaining PFAS chemicals on the Inventory. Comments generated by
this document will enable EPA to determine if any remaining uses exist.

D. Why is EPA Taking this Action?

    EPA believes that the manufacture or import for any use of the PFAS
chemicals listed in Table 3 of the proposed regulatory text occurring
after the 3M Company's global phase-out dates would significantly
increase the magnitude and duration of exposure to humans and the
environment to these chemicals. Given the similarity of the chemicals
in this proposal to the PFAS chemicals covered under 40 CFR 721.9582
and the health and environmental concerns described in this unit, EPA
believes that action on these PFAS chemicals is warranted.

IV. Determining a Significant New Use

    Section 5(a)(2) of TSCA requires that EPA's determination that a
use of a chemical substance is a significant new use must be made after
consideration of all relevant factors including:
     The projected volume of manufacturing and processing of a
chemical substance.
     The extent to which a use changes the type or form of
exposure of human beings or the environment to a chemical substance.
     The extent to which a use increases the magnitude and
duration of exposure of human beings or the environment to a chemical
substance.
     The reasonably anticipated manner and methods of
manufacturing, processing, distribution in commerce, and disposal of a
chemical substance.
    EPA construes the statute to allow consideration of any other
relevant factors, in addition to those enumerated in section 5(a)(2)(A)
through (D).
    To determine what would constitute a significant new use of the
PFAS chemicals listed in Table 3 of the proposed regulatory text, EPA
considered relevant information about the toxicity, exposure, and
environmental effects of the substances as well as the four factors
listed in section 5(a)(2) of TSCA.
    As described in Unit III., EPA has concerns regarding the
reproductive and subchronic toxicity, persistence, and bioaccumulative
potential of the chemical substances that are included in this proposed
SNUR. Any use of these PFAS chemicals would continue to add to the
reservoir of PFASA in the environment, resulting in additional human/
animal exposure.
    Furthermore, the specific perfluoroalkylsulfonyl fluoride (PASF)
precursors required to manufacture the PFAS chemicals included in this
proposal are no longer being manufactured and 3M Company, the principal
U.S. manufacturer of PFAS chemicals, has committed to using
perfluorobutane sulfonate (PFBS) (a four carbon (C4) based PFAS). The
Agency is also not aware of any uses or imports in the United States of
the PFAS chemicals included in this proposal.
    Available information indicates that there is no ongoing
manufacture, import, or use of these PFAS chemicals in the United
States. Therefore, any manufacture, import, or use of these chemicals,
apart from the excepted uses, if determined to be ongoing based on
comments received on this proposed rule or other information, would be
considered a significant new use.
    Considering EPA's concerns about the toxicity and bioaccumulation
potential of the chemicals, EPA believes that individuals and the
environment could suffer adverse effects from their use. Since
indications are that manufacturing and importing have ceased, with the
possible exception of the four excepted uses, EPA believes that any new
manufacture, import, or use of these chemicals would significantly
increase the production volume and the magnitude and duration of
exposure of human beings and the environment to these chemical
substances. Consequently, EPA wants the opportunity to evaluate and
control, if appropriate, exposures associated with those activities.
    Based on these considerations, EPA is pursuing the following
objectives with regard to the use of the chemicals listed in Table 3 of
the proposed regulatory text:
     EPA wants to ensure that it would receive notice of any
person's intent to manufacture or import the listed chemicals for any
designated new use before that activity begins.
     EPA wants to ensure that it would have the opportunity to
review and evaluate data submitted in a SNUN before the notice
submitter begins manufacturing or importing the chemicals for any
designated new use.

     The required notice will provide EPA the opportunity to
evaluate intended significant new uses and associated activities before
they occur and, if necessary, to prohibit or limit those activities.

V. Test Data and Other Information

    EPA recognizes that section 5 of TSCA does not require the
development of any particular test data before submission of a SNUN.
Persons are required only to submit test data in their possession or
control and to describe any other data known to or reasonably
ascertainable by them (15 U.S.C. 2604(d); 40 CFR 721.25).
    SNUN submitters should be aware that EPA will be better able to
evaluate SNUNs that provide detailed information on:
     Human exposure and environmental releases that may result
from the significant new use of the chemical substance.
     Potential benefits of the chemical substance.
     Information on hazards and risks posed by the chemical
substance relative to hazards and risks posed by potential substitutes.
    Submitters should consider including with a SNUN any other
available studies on the chemical substances or studies on analogous
substances that may demonstrate that the significant new uses being
reported are unlikely to present an unreasonable risk.
    In view of the potential risks posed by these chemicals, potential
SNUN submitters should include data that would permit a reasoned
evaluation of risks posed by these chemicals. EPA encourages persons to
consult with the Agency before submitting a SNUN for these substances.
As part of this optional pre-notice consultation, EPA would discuss
specific data it believes would be useful in evaluating a significant
new use. A SNUN submitted without sufficient data to reasonably
evaluate risks posed by a significant new use of one of the listed
chemicals may increase the likelihood that EPA will take action under
TSCA section 5(e) to prohibit or limit activities associated with these
chemicals.

VI. SNUN Submissions

    SNUNs should be mailed to the Environmental Protection Agency, OPPT
Document Control Office (7407M), 1200 Pennsylvania Ave., NW.,
Washington, DC 20460-0001. Information must be submitted in the form
and manner set forth in EPA Form No. 7710-25. This form is available
from the Environmental Assistance Division (7408M), OPPT, Environmental
Protection Agency, 1200 Pennsylvania Ave., NW., Washington, DC 20460-
0001 (see 40 CFR 721.25(a) and 720.40(a)(2)(i)).

VII. Alternatives

    Before proposing this SNUR, EPA considered promulgating a TSCA
section 8(a) reporting rule for the listed chemicals. Under such a
rule, EPA could generally require any person to report information to
the Agency when they intend to manufacture, import, or process a listed
chemical. However, in the case of these particular substances, the use
of TSCA section 8(a) rather than SNUR authority would have several
drawbacks. First, EPA would not be able to take immediate follow-up
regulatory action under TSCA sections 5(e) or 5(f) to prohibit or limit
the activity before it begins. In addition, EPA may not receive
important information from small businesses, because such firms
generally are exempt from TSCA section 8(a) reporting requirements. In
view of the level of health and environmental concerns about the
chemicals listed in Table 3 of the proposed regulatory text, EPA
believes that a TSCA section 8(a) rule for these substances would not
meet EPA's regulatory objectives.

VIII. Applicability of Proposed Rule to Uses Occurring Before Effective
Date of the Final Rule

    As discussed in the Federal Register of April 24, 1990 (55 FR
17376), EPA believes that the intent of TSCA section 5(a)(1)(B) is best
served by designating a use as a ``significant new use'' as of the
proposal date of the SNUR, rather than as of the effective date of the
final rule. If uses begun after publication of the proposed SNUR were
considered to be ongoing rather than new, it would be difficult for EPA
to establish notification requirements, because any person could defeat
the SNUR by initiating the proposed significant new use before the
proposed rule became final.
    Any person who begins commercial manufacture or import for any use
of any of the chemical substances listed in Table 3 of the proposed
regulatory text after publication of this proposed SNUR must stop such
activity before the effective date of the final rule. All persons will
have to meet all SNUR notice requirements and wait until the end of the
notice review period, including all extensions, before engaging in any
activities designated as significant new uses. If, however, persons who
begin commercial manufacture or import of any of the chemical
substances listed in Table 3 of the proposed regulatory text between
the proposal and the effective date of the final SNUR meet the
conditions of advance compliance as codified at 40 CFR 721.45(h), those
persons would be considered to have met the requirements of the final
SNUR for those activities.

IX. Issue for Comment

    EPA is especially interested in comments on whether there is any
current manufacture or import of any of the chemicals listed in Table 3
of the proposed regulatory text, including for the uses that would be
excepted as proposed in accordance with 40 CFR 721.9582(a)(2)(iii). The
Agency is not aware of any uses or imports in the United States of the
remaining PFAS chemicals on the Inventory. Comments generated by this
document will enable EPA to determine if any remaining uses exist, and
therefore the need for the proposed, or other, exemptions, based on
manufacture or import for an ongoing use.

X. Economic Analysis

    EPA has evaluated the potential costs of establishing SNUR
reporting requirements for potential manufacturers, including
importers, of the chemical substances who would be subject to the final
rule. While there is no precise way to calculate the total annual cost
of compliance with the final rule, EPA estimates that the reporting
cost for submitting a SNUN is $7,267, including a $2,500 user fee (Ref.
16). EPA believes that there will be few, if any, SNUNs submitted.
EPA's complete economic analysis is available in the public docket for
this proposed rule (Ref. 16).
    Under section 12(b) of TSCA, exporters must notify EPA if they
export or intend to export a chemical substance or mixture for which,
among other things, a rule has been proposed or promulgated under TSCA
section 5. Notice must be provided for the first export or intended
export to a particular country in a calendar year. In an economic
analysis of an amendment to the rules implementing TSCA section 12(b),
EPA estimated that the one-time cost of preparing and submitting an
export notification was $62.60 in 1992, or $93.02 when inflated to 2003
dollars by a factor of approximately 1.5, from the Employment Cost
Index for White Collar Occupations. The total costs of export
notification will vary by chemical, depending on the number of required
notifications (i.e., the number of countries to which the chemical is
exported). EPA is unable to make any estimate of the likely number of
export notifications for chemicals covered in this SNUR (Ref. 16).

XII. Statutory and Executive Order Reviews

A. Executive Order 12866: Regulatory Planning and Review

    Under Executive Order 12866, entitled Regulatory Planning and
Review (58 FR 51735, October 4, 1993), the Office of Management and
Budget (OMB) has determined that this proposed SNUR is not a
``significant regulatory action'' because this rule does not meet the
criteria in section 3(f) of the Executive Order.

B. Paperwork Reduction Act

    According to the Paperwork Reduction Act (PRA), 44 U.S.C. 3501 et
seq., an Agency may not conduct or sponsor, and a person is not
required to respond to a collection of information that requires OMB
approval under the PRA, unless it has been approved by OMB and displays
a currently valid OMB control number. The OMB control numbers for EPA's
regulations in title 40 of the CFR, after appearing in the Federal
Register, are listed in 40 CFR part 9, and included on the related
collection instrument or form, if applicable.
    The information collection requirements related to this action have
already been approved by OMB pursuant to the PRA under OMB control
number 2070-0038 (EPA ICR No. 1188). This action does not impose any
burden requiring additional OMB approval. The burden for submitting a
SNUN is estimated to average 107 hours per submission. This burden
estimate includes the time needed to review instructions, search
existing data sources, gather and maintain the data needed, and
complete, review, and submit the required SNUN.
    Send any comments about the accuracy of the burden estimate, and
any suggested methods for minimizing respondent burden, including
through the use of automated collection techniques, to the Director,
Collection Strategies Division, Office of Environmental Information
(2822T), Environmental Protection Agency, 1200 Pennsylvania Ave., NW.,
Washington, DC 20460-0001. Please remember to include the OMB control
number in any correspondence, but do not submit any completed forms to
this address.

C. Regulatory Flexibility Act

    Pursuant to section 605(b) of the Regulatory Flexibility Act (RFA)
(5 U.S.C. 601 et seq.), the Agency hereby certifies that promulgation
of this SNUR would not have a significant adverse economic impact on a
substantial number of small entities. The rationale supporting this
conclusion is as follows. A SNUR applies to any person (including small
or large entities) who intends to engage in any activity described in
the rule as a ``significant new use.'' By definition of the word
``new,'' and based on all information currently available to EPA, it
appears that no small or large entities presently engage in such
activity. Because a SNUR requires only that any person who intends to
engage in such activity in the future must first notify EPA by
submitting a SNUN, no economic impact would even occur until someone
decides to engage in those activities. Although some small entities may
decide to conduct such activities in the future, EPA cannot presently
determine how many, if any, there may be. However, EPA's experience to
date is that, in response to the promulgation of over 1,000 SNURs, the
Agency receives on average only 10 SNUNs per year. Of those SNUNs
submitted, none appear to be from small entities in response to any
SNUR. In addition, the estimated reporting cost for submission of a
SNUN (see Unit X.), are minimal regardless of the size of the firm.
Therefore, EPA believes that the potential economic impact of complying
with this SNUR is not expected to be significant nor adversely impact a
substantial number of small entities. In a SNUR that published on June
2, 1997 (62 FR 29684) (FRL-5597-1), the Agency presented its general
determination that proposed and final SNURs are not expected to have a
significant economic impact on a substantial number of small entities,
which was provided to the Chief Counsel for Advocacy of the Small
Business Administration.

D. Unfunded Mandates Reform Act

    Based on EPA's experience with proposing and finalizing SNURs,
State, local, and Tribal governments have not been impacted by these
rulemakings, and EPA does not have any reason to believe that any
State, local, or Tribal government would be impacted by this
rulemaking. As such, EPA has determined that this regulatory action
would not impose any enforceable duty,

contain any unfunded mandate, or otherwise have any affect on small
governments subject to the requirements of sections 202, 203, 204, or
205 of the Unfunded Mandates Reform Act of 1995 (UMRA) (Public Law 104-
4).

E. Executive Order 13132: Federalism

    This action would not have a substantial direct effect on States,
on the relationship between the national government and the States, or
on the distribution of power and responsibilities among the various
levels of government, as specified in Executive Order 13132, entitled
Federalism (64 FR 43255, August 10, 1999).

F. Executive Order 13175: Consultation and Coordination with Indian
Tribal Governments

    This proposed rule would not have Tribal implications because it is
not expected to have substantial direct effects on Indian Tribes. This
proposed rule would not significantly or uniquely affect the
communities of Indian Tribal governments, nor would it involve or
impose any requirements that affect Indian Tribes. Accordingly, the
requirements of Executive Order 13175, entitled Consultation and
Coordination with Indian Tribal Governments (65 FR 67249, November 6,
2000), do not apply to this proposed rule.

G. Executive Order 13045: Protection of Children from Environmental
Health Risks and Safety Risks

    This action is not subject to Executive Order 13045, entitled
Protection of Children from Environmental Health Risks and Safety Risks
(62 FR 19885, April 23, 1997), because this is not an economically
significant regulatory action as defined by Executive Order 12866, and
this action does not address environmental health or safety risks
disproportionately affecting children.

H. Executive Order 13211: Actions that Significantly Affect Energy
Supply, Distribution, or Use

    This proposed rule is not subject to Executive Order 13211,
entitled Actions Concerning Regulations That Significantly Affect
Energy Supply, Distribution, or Use (66 FR 28355, May 22, 2001),
because this action is not expected to affect energy supply,
distribution, or use.

I. National Technology Transfer Advancement Act

    In addition, since this action does not involve any technical
standards, section 12(d) of the National Technology Transfer and
Advancement Act of 1995 (NTTAA), Public Law 104-113, section 12(d) (15
U.S.C. 272 note), does not apply to this action.

J. Executive Order 12898: Federal Actions to Address Environmental
Justice in Minority Populations and Low-Income Populations

    This action does not entail special considerations of environmental
justice related issues as delineated by Executive Order 12898, entitled
Federal Actions to Address Environmental Justice in Minority
Populations and Low-Income Populations (59 FR 7629, February 16, 1994).

K. Executive Order 12988: Civil Justice Reform

    In issuing this proposed rule, EPA has taken the necessary steps to
eliminate drafting errors and ambiguity, minimize potential litigation,
and provide a clear legal standard for affected conduct, as required by
section 3 of Executive Order 12988, entitled Civil Justice Reform (61
FR 4729, February 7, 1996).
