Perfluoroalkyl Sulfonates; Significant New Use Rule

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: EPA is amending a significant new use rule (SNUR) under
section 5(a)(2) of the Toxic Substances Control Act (TSCA) to include
certain additional perfluoroalkyl sulfonate (PFAS) chemicals. EPA is
amending the PFAS SNUR at 40 CFR 721.9582 by adding a new Table 3 which
includes the PFAS chemicals currently on the public TSCA Inventory that
are not already covered by the SNUR. This rule requires 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 for the significant new uses described in this
document on or after November 8, 2007. EPA believes that this action is
appropriate because these chemical substances may be hazardous to human
health and the environment. This 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: This final rule is effective November 8, 2007.

ADDRESSES: EPA has established a docket for this action under docket
identification (ID) number EPA-HQ-OPPT-2005-0015. All documents in the

SUPPLEMENTARY INFORMATION:

I. Does this Action Apply to Me?

    You may be potentially affected by this action if you manufacture
or import any of the chemical substances that are listed in Table 3 of
the regulatory text. This action may also affect certain entities
through pre-existing import certification and export notification rules
under TSCA. Persons who 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 the corresponding regulations at 19 CFR
12.118 through 12.127 and 127.28. Those persons must certify that the
shipment of the chemical substance complies with all applicable rules
and orders under TSCA, including any 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 rule 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) or
chemical exporters of one or more of the subject chemical substances
(NAICS codes 325 and 324110), e.g., chemical manufacturing and
petroleum refineries.
     Establishments (NAICS code 332813), e.g., primarily
engaged in electroplating, plating, anodizing, coloring, buffing,
polishing, cleaning, and sandblasting metals and metal products.
    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 described 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.

II. Background

    In the Federal Register of March 10, 2006 (71 FR 12311) (FRL-7740-
6), EPA proposed to add 183 PFAS chemicals to the SNUR at 40 CFR
721.9582. The 183 chemicals being added to the SNUR are listed in Table
3 in the regulatory text of this document. The chemicals listed in
Table 3 are on the public TSCA Inventory and have the characteristic
PFAS chemical structure of a perfluorinated carbon chain (Rf) greater
than, or equal to, C5 attached to an SO2 group connected to the rest of
the molecule. In addition, the proposal also included those chemicals
with Rf ranges of perfluorinated carbon chains shorter than C5, and
greater than C5, for example, C4-C12 and C6-C12. In this SNUR, this
PFAS chemical structure is referred to as the Rf moiety. EPA believed
the action was 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.
of the March 10, 2006 document. EPA also proposed 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.

A. What Action is the Agency Taking?

    The Agency is designating as a ``significant new use'' the
manufacture, including import, of the chemical substances listed in
Table 3 of the regulatory text, for any use, except for the excluded
uses described in this unit. Based on comments received during the
public comment period and related communications, EPA learned of an
ongoing use of seven PFAS chemicals as a component of an etchant used
in the plating process to produce electronic devices. Consequently,
that use has been excluded from this SNUR for those seven chemicals.
See Sec.  721.9582(a)(5) or the discussion in this unit of the
significant new uses for a list of those chemicals.
    In addition, the public comments described the ongoing use of PFAS
chemicals as a fume/mist suppressant in metal finishing and plating
baths. However, based on searches of the Internet which generated
information on PFAS from the Organization for Economic Cooperation and
Development (OECD), industry, and information from the California Air
Resources Board (Refs. 1 and 2), EPA has concluded that only one
chemical in Table 3, tetraethylammonium perfluorooctanesulfonate (CAS
No. 56773-42-3), is used in this application. Therefore, EPA has
excluded that use of this chemical from this SNUR. However, EPA remains
concerned about this use, because at least two commenters to this SNUR
noted that small quantities of this PFAS surfactant are released in the
routine renewal of the plating baths. In addition, since the close of
the public comment period, EPA has learned from a 2007 survey by
Minnesota of over 30 wastewater treatment plants that PFOS, which is
the anionic counterion of this PFAS surfactant, is appearing in
wastewater treatment plant influent, effluent, and sludge associated
with the fume/mist suppressant use in metal finishing and plating
baths. As a result of these concerns, although outside the scope of
this rule, EPA will continue to work with state agencies and industry
to identify best management practices for minimizing the release of
this PFAS surfactant.
    A chemical fume (or mist) suppressant refers to any chemical agent
that reduces or suppresses fumes or mists at the surface of an
electroplating bath or solution. Chemical fume suppressants are
``surface-active'' compounds that can be added directly to a chrome
plate acid bath to reduce or control misting (Ref. 3). PFAS chemicals
are effective fume suppressants because of their surfactant properties.
Fume suppressants act by reducing the plating bath surface tension
which then inhibits misting. Misting occurs when bubbles break free of
a liquid bath's surface and burst in the air. When the surface tension
of a bath is lowered, as occurs with the use of PFAS fume suppressants,
gases escape at the surface of the plating bath solution with less of a
``bursting'' effect, forming less mist (Ref. 4). Such fume
suppressants, as opposed to other chemical surfactants, are used in the
plating industry because the PFAS fume suppressant is able to withstand
the harsh conditions of plating baths while lowering the plating bath
surface tension to levels specified by current regulatory standards
(Ref. 5). While several of these PFAS chemicals were developed for this
use, only one is being used currently.
    The plating fume suppressant that contains tetraethylammonium

perfluorooctanesulfonate (CAS No. 56773-42-3) to reduce surface tension
is different than the types of fume suppressants used in the plating
industry that produce a foam blanket, and which can be used alone or in
conjunction with PFAS fume suppressants.
    This rule requires persons to notify EPA at least 90 days before
commencing the manufacture (including import) of the chemical
substances identified in Table 3 of the regulatory text for any use,
except:
     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 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.
     Use of: 1-Pentanesulfonic acid, 1,1,2,2,3,3,4,4,5,5,5-
undecafluoro-, potassium salt (CAS No. 3872-25-1); Glycine, N-ethyl-N-
[(tridecafluorohexyl)sulfonyl]-, potassium salt (CAS No. 67584-53-6);
Glycine, N-ethyl-N-[(pentadecafluoroheptyl)sulfonyl]-, potassium salt
(CAS No. 67584-62-7); 1-Heptanesulfonic acid,
1,1,2,2,3,3,4,4,5,5,6,6,7,7,7-pentadecafluoro-, ammonium salt (CAS No.
68259-07-4); 1-Heptanesulfonamide, N-ethyl-
1,1,2,2,3,3,4,4,5,5,6,6,7,7,7-pentadecafluoro- (CAS No. 68957-62-0);
Poly(oxy-1,2-ethanediyl), .alpha.-[2-
[ethyl[(pentadecafluoroheptyl)sulfonyl]amino]ethyl]-.omega.-methoxy-
(CAS No. 68958-60-1); or 1-Hexanesulfonic acid,
1,1,2,2,3,3,4,4,5,5,6,6,6-tridecafluoro-, compd. with 2,2'-
iminobis[ethanol] (1:1) (CAS No. 70225-16-0) as a component of an
etchant, including a surfactant or fume suppressant, used in the
plating process to produce electronic devices.
     Use of tetraethylammonium perfluorooctanesulfonate (CAS
No. 56773-42-3) as a fume/mist suppressant in metal finishing and
plating baths. Examples of such metal finishing and plating baths
include: Hard chrome plating; decorative chromium plating; chromic acid
anodizing; nickel, cadmium, or lead plating; metal plating on plastics;
and alkaline zinc plating.
     Use as an intermediate only to produce other chemical
substances to be used solely for the uses listed in bullets 1, 2, or 3
of this unit.

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 rule after considering all
relevant factors, including those listed in TSCA section 5(a)(2). Once
EPA determines that a use of a chemical substance is a significant new
use, TSCA section 5(a)(1)(B) 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 (15 U.S.C.
2604(a)(1)(B)). The mechanism for reporting under this requirement is
established under 40 CFR 721.5.

C. Applicability of General Provisions

    General provisions for SNURs appear under 40 CFR part 721, subpart
A. These provisions describe persons subject to the rule, recordkeeping
requirements, exemptions to reporting requirements, and applicability
of the rule to uses occurring before the effective date of the final
rule. Provisions relating to user fees appear at 40 CFR part 700.
According to 40 CFR 721.1(c), persons subject to this SNUR must comply
with the same notice requirements and EPA regulatory procedures as
submitters of Premanufacture Notices (PMNs) under TSCA section
5(a)(1)(A). In particular, these requirements include the information
submission requirements of TSCA section 5(b) and 5(d)(1), the
exemptions authorized by TSCA section 5(h)(1), (h)(2), (h)(3), and
(h)(5), and the regulations at 40 CFR part 720. Once EPA receives a
SNUN, EPA may take regulatory action under TSCA section 5(e), 5(f), 6
or 7 to control the activities for which it has received the SNUN. If
EPA does not take action, EPA is required under TSCA section 5(g) to
explain in the Federal Register its reasons for not taking action.
    Persons who export or intend to export a chemical 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 import a chemical substance identified in a final SNUR are
subject to the TSCA section 13 import certification requirements, which
appear at 19 CFR 12.118 through 12.127 and 127.28. Such persons must
certify that the shipment of the chemical substance complies with all
applicable rules and orders under TSCA, including any SNUR
requirements. The EPA policy in support of import certification appears
at 40 CFR part 707, subpart B.

III. Objectives and Rationale for this Final Rule

A. Objectives

    Based on the considerations in Unit III. of the preamble to the
proposed SNUR and in Unit III.B. and Unit IV. of this preamble, by
issuing this SNUR, EPA will achieve the following objectives with
regard to the significant new uses that are designated in this rule:
     EPA will receive notice of any person's intent to
manufacture or import any chemical listed in Table 3 of the regulatory
text for the described significant new use before that activity begins.
     EPA will have an opportunity to review and evaluate data
submitted in a SNUN before the notice submitter begins to manufacture
or import any chemicals listed in Table 3 of the regulatory text for a
significant new use.
     EPA will have an opportunity to regulate prospective
manufacturers or importers of any chemical listed in Table 3 of the
regulatory text before a significant new use of the chemical substance
occurs, provided that regulation is warranted pursuant to TSCA sections
5(e), 5(f), 6 or 7.

B. Rationale

    EPA has concerns regarding adverse human health and environmental
effects of PFAS. It is highly persistent in the environment, it tends
to bioaccumulate, and it is toxic. In its voluntary phase-out of
perfluorooctane sulfonate (PFOS) and PFOS-related products, the 3M
Company, which had been the sole U.S. manufacturer of the chemicals,
committed to stop production of all perfluoroalkyl sulfonic acid
products with alkyl chain lengths of C8 or greater. 3M completed its
phase-out of PFOS production in 2002, which led to a significant
reduction in the use of all PFAS-related substances.
    Production of the 183 PFAS chemicals in Table 3 is limited to the
excluded uses described in 40 CFR 721.9582(a)(3) and in Unit II.A. of
this document. Production volumes and exposures have been decreasing.
Any manufacture or import for a significant new use is expected to
significantly increase exposures beyond levels that now occur. EPA is
concerned that manufacture or import of the PFAS chemicals listed in
Table 3 of the regulatory text for any uses not

excluded by this SNUR could be reinitiated in the future. The notice
required by this SNUR will provide EPA with additional information to
evaluate activities associated with a significant new use and to
protect against unreasonable risks, if any, from exposure to the
substances.

IV. Significant New Use Determination

    Section 5(a)(2) of TSCA states 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 the use changes the type or form of
exposure of humans or the environment to a chemical substance.
     The extent to which the 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.
    TSCA section 5(a)(2) authorizes EPA to consider any other relevant
factors in addition to the factors enumerated in the bulleted items.
    To determine what would constitute a significant new use of a
chemical listed in Table 3 of the regulatory text, EPA considered
relevant information about the toxicity of the PFAS substances, likely
human exposures and environmental releases associated with possible
uses, and the four factors listed in this unit.
    As described in Unit III. of the proposed SNUR, EPA has concerns
regarding the reproductive and subchronic toxicity, persistence, and
bioaccumulative potential of the chemical substances that are included
in this SNUR. These concerns lead the Agency to believe that humans and
the environment could suffer adverse effects from their use. Any use of
these PFAS chemicals would continue to add to the reservoir of
perfluoroalkyl sulfonic acids (PFASA) in the environment, resulting in
additional human/environmental exposure. There is evidence that PFAS-
containing chemicals degrade to perfluoroalkyl sulfonic acids (PFASA),
which exist in the anionic form in the environment, or to PFASA
precursors.
    The latest information available to EPA indicates that the
chemicals listed in Table 3 of the regulatory text are no longer being
manufactured for any uses other than the excluded uses described in
Unit II. of this SNUR. EPA believes that reintroduction of PFAS for any
use other than the listed uses EPA has identified could significantly
increase the production volume, and the magnitude and duration of
exposure to humans and the environment to these chemical substances
over that which would otherwise exist. Consequently, EPA wants the
opportunity to evaluate and control, if appropriate, exposures
associated with those activities before they occur. Based upon the
relevant factors discussed in this unit, EPA has determined that the
manufacture, including import, of any of the chemicals listed in Table
3 of the regulatory text for any use other than those described in Unit
II., is a significant new use.
    EPA will continue to evaluate the excluded uses and may pursue
additional regulatory action under TSCA, if necessary in the future.

V. Test Data and Other Information

    TSCA section 5 does not require the development of any particular
test data before submission of a SNUN. Persons are required to submit
only test data in their possession or under their control and to
describe any other data known to or reasonably ascertainable by them
(15 U.S.C. 2604(d); 40 CFR 721.25).
    In view of the Agency's concerns regarding activities associated
with the significant new use(s) of any chemical listed in Table 3 of
the regulatory text, EPA recommends that SNUN submitters include data
that would permit a reasoned evaluation of risks posed by the chemical
substance during its manufacture, import, processing, use, distribution
in commerce, or disposal. EPA encourages persons to consult with the
Agency before submitting a SNUN. As part of this optional pre-notice
consultation, EPA would discuss specific data it believes may be useful
in evaluating a significant new use. SNUNs submitted for significant
new uses without any test data may increase the likelihood that EPA
will take action under TSCA section 5(e) to prohibit or limit
activities associated with the chemical.
    SNUN submitters should be aware that EPA will be better able to
evaluate SNUNs that provide detailed information on:
     Human exposures and environmental releases that may result
from the significant new uses of the chemical substance.
     Potential benefits of the chemical substance.
     Information on risks posed by the chemical substance
compared to risks posed by potential substitutes.

VI. SNUN Submissions

    SNUNs must 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), 1200 Pennsylvania
Ave., NW., Washington, DC 20460-0001 (see 40 CFR 721.25 and 720.40).
Forms and information are also available electronically at http://www.epa.gov/opptintr/newchems/pubs/pmnforms.htm
.

    As discussed in Unit V., EPA recommends that submitters consult
with the Agency prior to submitting a SNUN to discuss what data may be
useful in evaluating a significant new use. Discussions with the Agency
prior to submission can afford submitters ample time to conduct any
tests that might be helpful in evaluating the risks posed by the
substance.

VII. Applicability of 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 has decided that the intent of section 5(a)(1)(B) of TSCA
is best served by designating a use as a significant new use as of the
date of publication of the proposed rule rather than as of the
effective date of the final rule. If uses begun after publication of
the proposed rule were considered ongoing rather than new, it would be
difficult for EPA to establish SNUR notice requirements, because a
person could defeat the SNUR by initiating the proposed significant new
use before the rule became final, and then argue that the use was
ongoing as of the effective date of the final rule. Thus, persons who
may have begun commercial manufacture or import of the chemical
substances listed in Table 3 of the regulatory text for the significant
new uses listed in this final SNUR after the proposal was published on
March 10, 2006, must stop that activity before the effective date of
this final rule. To resume their activities, these persons would have
to comply with all applicable SNUR notice requirements and wait until
the notice review period, including all extensions, expires. EPA has
promulgated provisions to allow persons to comply with this SNUR before
the effective date. If a person were to meet the conditions of advance
compliance under Sec.  721.45(h), that person would be considered to
have met the

requirements of the final SNUR for those activities.

VIII. Discussion of the Final Significant New Use Rule and Response to
Comments

    This action finalizes the SNUR proposed in the Federal Register on
March 10, 2006 (71 FR 12311). On April 10, 2006 (71 FR 18055) (FRL-
7779-7), EPA extended the closing date of the public comment period
from April 10, 2006 to May 10, 2006. On May 10, 2006 (71 FR 27217)
(FRL-8068-8), EPA further extended the closing date of the comment
period from May 10, 2006 to August 8, 2006.
    This final rule requires persons who intend to manufacture or
import any of the chemical substances listed in Table 3 of the
regulatory text for any use other than those excluded uses described in
Unit II.A. to submit a SNUN at least 90 days before commencing the
manufacture or importation of any of these chemicals.
    It should be noted that, in Table 3, some of the chemical names are
different from those in the previous proposed SNUR of March 10, 2006.
This is due to enhancement of the nomenclature or nomenclature changes
adopted by the Chemical Abstracts Service (CAS). CAS is now using the
16th Collective Index (known as the ACI). EPA has updated the
previously used 9th Collective Index names to reflect the latest
changes by CAS. The CAS numbers and chemicals, however, remain the
same. In some cases, the extremely long ACI names have been truncated
to save space. Each complete ACI name is available at the EPA website
in the TSCA Substance Registry System (SRS) at http://www.epa.gov/srs.

Also, to be consistent with the other tables already in the SNUR, the
order of the listing has been reversed from the descending order used
in the proposed SNUR to ascending order used in this final SNUR.
    The Agency reviewed and considered all comments received related to
the proposed rule. Copies of all non-CBI comments are available at
http://www.regulations.gov in the public docket for this action, EPA-

HQ-OPPT-2005-0015. A discussion of the comments germane to the
rulemaking, and the Agency's responses, follows.
    1. Comment summary. Metal plating and finishing industries that
currently use specific PFAS chemicals to meet regulatory standards for
hexavalent chromium (Cr(VI)) emissions established by Federal and State
regulations need to be excluded from the SNUR as a current use (similar
to the exclusions for semiconductors and imaging products in previously
promulgated SNURs). The releases and exposures to PFAS associated with
the industry are comparably of much less concern than those related to
nickel (Ni) and hexavalent chromium (Cr(VI)) which result when PFAS
fume suppressants are not used. In addition, the economic and
competitive liabilities will cripple this domestic industry if these
chemicals are no longer permitted to be used. Commenters described
their continuing efforts to find greener, safer substitutes, but
explained that for many uses there are no viable alternatives.
Commenters said that the metal finishing industry continues to support
research and development efforts to identify commercially viable
alternatives to hexavalent chromium plating chemistries. To date,
alternative technologies show some promise for niche applications, but
have not gained widespread commercial application due to: 1) The
superior coating performance in decorative, functional, and corrosion
protection applications for hexavalent chromium plating; 2) cost
effective applications; 3) broad and flexible ranges of use; and 4)
strong customer/market preferences for hexavalent chromium plating.
    Response. EPA now recognizes that the metal plating and finishing
industries currently use a specific PFAS chemical, tetraethylammonium
perfluorooctanesulfonate (CAS No. 56773-42-3), to meet regulatory
standards for hexavalent chromium (Cr(VI)) emissions. Thus, EPA has
included this ongoing use of tetraethylammonium
perfluorooctanesulfonate, as described in Unit II.A., as an exclusion
in this SNUR, but encourages the continued exploration for possible
substitutes.
    2. Comment summary. Several specific uses of PFAS chemicals within
the semiconductor, integrated circuit, and microelectronics industries
were excluded from the previous two PFAS SNURs. The proposed SNUR
includes an additional 183 chemicals that would affect those same uses
in the same industry sectors, so the exclusions in the previous two
SNURs should apply to the 183 chemicals listed in this SNUR. Also,
these uses constitute ongoing uses, not significant new uses. The
semiconductor industry has supported reduction initiatives and dialogue
through trade associations in other regions around the world. One
primary locus for reduction initiatives and dialogue has been the World
Semiconductor Council.
    Response. EPA recognizes that these are ongoing uses, and is
therefore not designating the uses as significant new uses of the
chemicals listed in Table 3. EPA is applying the exclusions described
in Unit II.A. to the list of 183 PFAS chemicals in Table 3 of the
regulatory text. EPA appreciates the efforts the semiconductor,
integrated circuit, and microelectronics industries have made in their
commitment to limit PFAS usage, to search for alternatives, and to
limit exposures and releases.
    3. Comment summary. Several specific uses of PFAS chemicals within
the photographic film, paper, and imaging industries were excluded from
the previous two PFAS SNURs. The proposed SNUR targets a broader list
of 183 chemicals for these applications in the same industry sector.
The exclusion in the previous SNURs should be applied to the 183
chemicals as well. Also, these uses constitute ongoing uses, not
significant new uses. Comments also stated that since concerns were
first raised in 2000, the photographic film, paper, and imaging
industries have aggressively pursued a voluntary risk reduction
strategy by investing heavily in research to find alternative
substances that possess the performance features described earlier for
PFAS.
    Response. EPA recognizes that these are ongoing uses, and is
therefore not designating the uses as significant new uses of the
chemicals listed in Table 3. EPA is applying the current exclusion
described in Unit II.A. to the list of 183 PFAS chemicals in Table 3 of
the regulatory text. EPA appreciates the efforts the photographic film,
paper, and imaging industries have made in their commitment to limit
PFAS usage, to search for alternatives, and to limit exposures and
releases.
    4. Comment summary. Commenter requested an explanation of how the
183 chemicals in this SNUR were chosen, and pointed out that some of
the alkyl ranges covered by the SNUR include chemicals with the PFAS
chemical structure (Rf moiety) with a C4 chain length.
    Response. EPA proposed that any PFAS chemical listed on the public
TSCA Inventory that contained the Rf moiety with a chain length of C5
or larger as part of the chemical identity would be subject to the
rulemaking process for this PFAS SNUR based on the similarity of these
chemicals to those currently included in 40 CFR 721.9582. That decision
addresses all PFAS chemicals on the public inventory that still remain
after the previous two SNURs and the evidence that manufacturers have
been moving to use the lower chain length PFAS chemicals. EPA also
included all ranges that contained > C4 constituents, even when that
lower end of the alkyl chain length

included C4 composition, in order to capture the higher homologues,
including C8, as discussed in the proposed rule.
    5. Comment summary. This comment summary is based on the sanitized
version of a Confidential Business Information (CBI) comment submitted
to docket ID number EPA-HQ-OPPT-2005-0015, DCN<PHONE_NUMBER>9,
as well as additional information later provided by the commenter. The
commenter originally indicated that it uses 13 of the 183 chemicals in/
as various specified applications. The commenter stated: 1) PFAS
substances are not directly or indirectly introduced into consumer
products; 2) the exclusions should be applied to the 183 chemicals in
Table 3 of the proposed SNUR; and 3) it uses these chemicals for a
specific use that is different from those uses that were excluded in
previous SNURs, i.e., as a component of an etchant, including a
surfactant or fume suppressant, used in the plating process to produce
electronic devices. The commenter also provided information for the low
risk applications of PFAS in these uses; e.g., low volume, low exposure
to workers, and low PFAS content, and product stewardship
accomplishments. The commenter requested an exclusion based on the
activities being ongoing for use as a component of an etchant,
including a surfactant or mist/fume suppressant, in plating processes
to produce electronic devices. The commenter also reduced the number of
chemicals involved in this ongoing etchant use from thirteen to seven
chemicals.
    Response. The Agency now recognizes the use of the seven chemicals
identified by the commenter as a component of an etchant used in the
plating process to produce electronic devices is an ongoing use.
Consequently, the Agency has included this use of any of the seven
chemicals as an exclusion in the final SNUR.

IX. Economic Analysis

A. SNUNs

    EPA evaluated the potential costs of establishing SNUR reporting
requirements for potential manufacturers and importers of the chemical
substances included in Table 3 of the regulatory text. While most
businesses are subject to a $2,500 user fee required by 40 CFR
700.45(b)(2)(iii), small businesses with annual sales of less than $40
million when combined with those of the parent company (if any) are
subject to a reduced user fee of $100 (40 CFR 700.45(b)(1)). The cost
of submitting a SNUN, estimated in EPA's Economic Analysis at $7,991,
including the user fee (Ref. 6), will be incurred only if a company
decides to pursue a significant new use as defined in this final SNUR.
Furthermore, while the expense of a SNUN and the uncertainties of
possible EPA regulation may discourage certain innovations, that impact
would be limited because such factors are unlikely to discourage an
innovation that has high potential value. EPA's complete economic
analysis is available in the public docket for this rule (See docket ID
number EPA-HQ-OPPT-2005-0015).

B. Export Notification

    Under section 12(b) of TSCA and implementing regulations at 40 CFR
part 707, subpart D, 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.
On November 14, 2006, EPA revised the export notification requirement
from an annual to a one-time requirement per each destination country
for each exporter of a chemical substance subject to TSCA sections
5(a)(2), 5(b), 5(e)(1), and 5(e)(2) (November 14, 2006, 71 FR 66234)
(FRL-8101-3). Previous to this amendment, exporters were required to
submit a notice the first time in the calendar year they exported a
particular chemical to a particular country. Notifications must include
the exporter's name and address, the chemical name, the date(s) of
export or intended export, the importing country (or countries), and
the section of TSCA under which EPA has taken action. 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).
    In the report, Final Economic Analysis of the Amendments to TSCA
Section 12(b) Export Notification Requirements (Ref. 7), it estimated
the one-time export notification cost for an exporter making 25
submissions in a year to be $1,076. For a single notification, the cost
would be $43.04 ($1,076/25). This supersedes an earlier 1992 EPA
estimate that the one-time cost of preparing and submitting an export
notification was $62.60, and the subsequent update of that figure for
inflation which was included in the economic analysis for the proposed
SNUR.
    The total costs of export notification will vary per chemical,
depending on the number of required notifications (i.e., 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.

XI. Statutory and Executive Order Reviews

A. Executive Order 12866

    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 SNUR is not a ``significant
regulatory action'' subject to review by OMB, because it 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 codified

in chapter 40 of the CFR, after appearing in the preamble of the final
rule, are listed in 40 CFR part 9, are displayed either by publication
in the Federal Register or by other appropriate means, such as on the
related collection instrument or form, if applicable. The display of
OMB control numbers in certain EPA regulations is consolidated in 40
CFR part 9. For the ICR activity contained in this final rule, in
addition to displaying the applicable OMB control number in this unit,
the OMB control number assigned to this ICR activity is already
included in the table in 40 CFR 9.1.
    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, at an estimated
cost of $5,491. 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. This
burden estimate does not include the $2,500 user fee for submission of
a SNUN ($100 for businesses with less than $40 million in annual
sales).
    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 factual basis for the
Agency's determination is presented in the small entity impact analysis
prepared as part of the economic analysis for this rule (Ref. 6), which
is summarized in Unit IX., and a copy of which is available in the
docket for this rulemaking. The following is a brief summary of the
factual basis for this certification.
    Under the RFA, small entities include small businesses, small
organizations, and small governmental jurisdictions. For purposes of
assessing the impacts of today's rule on small entities, small entity
is defined in accordance with the RFA as: (1) A small business as
defined by the Small Business Administration's (SBA) regulations at 13
CFR 121.201; (2) a small governmental jurisdiction that is a government
of a city, county, town, school district, or special district with a
population of less than 50,000; and (3) a small organization that is
any not-for-profit enterprise which is independently owned and operated
and is not dominant in its field.
    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 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 IX.), is minimal
regardless of the size of the entity. 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

    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

    This rule would not have Tribal implications because it is not
expected to have substantial direct effects on Indian Tribes. This 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 rule.

G. Executive Order 13045

    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

    This 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 and 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

    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).

XII. Congressional Review Act

    The Congressional Review Act, 5 U.S.C. 801 et seq., generally
provides that before a rule may take effect, the Agency promulgating
the rule must submit a rule report to each House of the Congress and
the Comptroller General of the United States. EPA will submit a report
containing this rule and other required information to the U.S. Senate,
the U.S. House of Representatives, and the Comptroller General of the
United States prior to publication of the rule in the Federal Register.
This rule is not a ``major rule'' as defined by 5 U.S.C. 804(2).
