Proposed Significant New Use Rules on Certain Chemical Substances

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing significant new use rules (SNURs) under the
Toxic Substances Control Act (TSCA) for 37 chemical substances which
were the subject of premanufacture notices (PMNs). Seventeen of these
chemical substances are subject to TSCA section 5(e) consent orders
issued by EPA. This action would require persons who intend to
manufacture, import, or process any of these 37 chemical substances for
an activity that is designated as a significant new use by this
proposed rule to notify EPA at least 90 days before commencing that
activity. The required notification would provide EPA with the
opportunity to evaluate the intended use and, if necessary, to prohibit
or limit that activity before it occurs.

DATES: Comments must be received on or before April 26, 2013.

SUPPLEMENTARY INFORMATION:

I. General Information

A. Does this action apply to me?

    You may be potentially affected by this action if you manufacture,
import, process, or use the chemical substances in this proposed rule.
The following list of North American Classification System (NAICS)
codes is not intended to be exhaustive, but rather provides a guide to
help readers determine whether this document applies to them.
Potentially affected entities may include:
     Manufacturers, importers, or processors of one or more
subject chemical substances (NAICS codes 325 and 324110), e.g.,
chemical manufacturing and petroleum refineries.
    This action may also affect certain entities through pre-existing
import certification and export notification rules under TSCA. Chemical
importers are subject to the TSCA section 13 (15 U.S.C. 2612) import
certification requirements promulgated at 19 CFR 12.118 through 12.127;
see also 19 CFR 127.28. Chemical importers must certify that the
shipment of the chemical substance complies with all applicable rules
and orders under TSCA. Importers of chemicals subject to a final SNUR
must certify their 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 a proposed or final SNUR are
subject to the export notification provisions of TSCA section 12(b) (15
U.S.C. 2611(b)) (see Sec.  721.20) and must comply with the export
notification requirements in 40 CFR part 707, subpart D.

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 email. 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 ID 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 your estimate in sufficient detail to allow for it to be
reproduced.
    vi. Provide specific examples to illustrate your concerns and
suggest 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?

    These proposed SNURs would, when finalized, require persons to
notify EPA at least 90 days before commencing the manufacture, import,
or processing of the specific chemical substances identified in the
PMNs for any activity designated by these SNURs as a significant new
use. Receipt of such notices allows EPA to assess risks that may be
presented by the intended uses and, if appropriate, to regulate the
proposed use before it occurs. Additional rationale and background to
these rules are more fully set out in the preamble to EPA's first
direct final SNUR published in the Federal Register of April 24, 1990
(55 FR 17376). Consult that preamble for further information on the
objectives, rationale, and procedures for SNURs and on the basis for
significant new use designations, including provisions for developing
test data.

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 the four bulleted TSCA section 5(a)(2)
factors listed in Unit III. Once EPA determines that a use of a
chemical substance is a significant new use, TSCA section 5(a)(1)(B)
and 40 CFR part 721 require 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. Persons who must report
are described in Sec.  [emsp14]721.5.

C. Applicability of General Provisions

    General provisions for SNURs appear in 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 Sec.  [emsp14]721.1(c), persons subject to these SNURs
must comply with the same SNUN requirements and EPA regulatory
procedures as submitters of 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.

III. 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 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.
    In addition to these factors enumerated in TSCA section 5(a)(2),
the statute authorized EPA to consider any other relevant factors.
    To determine what would constitute a significant new use for the 37
chemical substances that are the subject of these proposed SNURs, EPA
considered relevant information about the toxicity of the chemical
substances, likely human exposures and environmental releases
associated with possible uses, taking into consideration the four
bulleted TSCA section 5(a)(2) factors listed in this unit.

IV. Substances Subject to This Proposed Rule

    EPA is proposing to establish significant new use and recordkeeping
requirements for 37 chemical substances in 40 CFR part 721, subpart E.
In this unit, EPA provides the following information for each chemical
substance:
     PMN number.
     Chemical name (generic name, if the specific name is
claimed as CBI).
     Chemical Abstracts Service (CAS) number (if assigned for
non-confidential chemical identities).
     Basis for the TSCA section 5(e) consent order or, for TSCA
non-section 5(e) SNURs, the basis for the SNUR (i.e., SNURs without
TSCA section 5(e) consent orders).
     Tests recommended by EPA to provide sufficient information
to evaluate the chemical substance (see Unit VIII. for more
information).
     CFR citation assigned in the regulatory text section of
this proposed rule.
    This proposed rule includes 14 PMN substances whose reported
chemical names include the term ``carbon nanotube'' or ``carbon
nanofibers.'' Because of a lack of established nomenclature for carbon
nanotubes, the TSCA Inventory names for carbon nanotubes are currently
in generic form, e.g., carbon nanotube (CNT), multi-walled carbon
nanotube (MWCNT), double-walled carbon nanotube (DWCNT), or single-
walled carbon nanotube (SWCNT). EPA uses the specific structural
characteristics provided by the PMN submitter to more specifically
characterize the TSCA Inventory listing for an individual CNT. All
submitters of new chemical notices for CNTs have claimed those specific
structural characteristics as CBI. EPA is publishing the generic
chemical name along with the PMN number to identify that a distinct
chemical substance was the subject of the PMN without revealing the
confidential chemical identity of the PMN substance. Confidentiality
claims preclude a more detailed description of the identity of these
CNTs. If an intended manufacturer, importer, or processor of CNTs is
unsure of whether its CNTs are subject to this proposed SNUR or any
other SNUR, the company can either contact EPA or obtain a written
determination from EPA pursuant to the bona fide procedures at Sec.
721.11. EPA is using the specific structural characteristics for all
CNTs submitted as new chemical substances under TSCA to help develop
standard nomenclature for placing these chemical substances on the TSCA
Inventory. EPA has compiled a generic list of those structural
characteristics entitled ``Material Characterization of Carbon
Nanotubes for Molecular Identity (MI) Determination & Nomenclature.'' A
copy of this list is available in the docket for these proposed SNURs
under docket ID number EPA-HQ-OPPT-2012-0727. If EPA develops a more
specific generic chemical name for these materials, that name will be
made publicly available.
    The regulatory text section of this proposed rule specifies the
activities designated as significant new uses. Certain new uses,
including exceeding production volume limits (i.e., limits on
manufacture and importation volume) and other uses designated in this
proposed rule, may be claimed as CBI.
    This proposed rule includes 17 PMN substances for which EPA
determined, pursuant to TSCA section 5(e), that uncontrolled
manufacture, import, processing, distribution in commerce, use, and
disposal may present an unreasonable risk of injury to human health or
the environment. Accordingly, these substances are subject to ``risk-
based'' consent orders under TSCA section 5(e)(1)(A)(ii)(I). Those
consent orders require protective measures to limit exposures or
otherwise mitigate the potential unreasonable risk. The so-called
``section 5(e) SNURs'' on these PMN substances are proposed pursuant to
Sec.  721.160, and are based on and consistent with the provisions in
the underlying consent orders. The section 5(e) SNURs designate as a
``significant new use'' the absence of the protective measures required
in the corresponding consent orders.
    Where EPA determined that the PMN substance may present an
unreasonable risk of injury to human health via inhalation exposure,
the underlying TSCA section 5(e) consent order usually requires, among
other things, that potentially exposed employees wear specified
respirators unless actual measurements of the workplace air show that
air-borne concentrations of the PMN substance are below a New Chemical
Exposure Limit (NCEL) that is established by EPA to provide adequate
protection to human health. In addition to the actual NCEL
concentration, the comprehensive NCELs provisions in TSCA section 5(e)
consent orders, which are modeled after Occupational Safety and Health
Administration (OSHA) Permissible Exposure Limits (PELs) provisions,
include requirements addressing performance criteria for sampling and
analytical methods, periodic monitoring, respiratory protection, and
recordkeeping. However, no comparable NCEL provisions currently exist
in 40 CFR part 721, subpart B, for SNURs. Therefore, for these cases,
the individual SNURs in 40 CFR part 721, subpart E, will normally state
that persons subject to the SNUR who wish to pursue NCELs as an
alternative to the Sec.  721.63 respirator requirements may request to
do so under Sec.  [emsp14]721.30. EPA expects that persons whose Sec.
721.30 requests to use the NCELs approach for SNURs are approved by EPA
will be required to comply with NCELs provisions that are comparable to
those contained in the corresponding TSCA section 5(e) consent order
for the same chemical substance.
    This proposed rule also includes SNURs on 20 PMN substances that
are not subject to consent orders under TSCA section 5(e). In these
cases, for a variety of reasons, EPA did not find that the use scenario
described in the PMN triggered the determinations set forth under TSCA
section 5(e). However, EPA does believe that certain changes from the
use scenario described in the PMN could result in increased exposures,
thereby constituting a ``significant new use.'' These so-called ``non-
section 5(e) SNURs'' are promulgated pursuant to Sec.  [emsp14]721.170.
EPA has determined that every activity designated as a ``significant
new use'' in all non-section 5(e) SNURs issued under Sec.
[emsp14]721.170 satisfies the two requirements stipulated in Sec.
721.170(c)(2), i.e., these significant new use activities, ``(i) are
different from those described in the premanufacture notice for the
substance, including any amendments, deletions, and additions of
activities to the premanufacture notice, and (ii) may be accompanied by
changes in exposure or release levels that are significant in relation
to the health or environmental concerns identified'' for the PMN
substance.

PMN Number P-00-835

    Chemical name: Substituted picolinate (generic).
    CAS number: Claimed as confidential.
    Basis for action: The PMN states that the substance will be used as
an intermediate in the manufacture of agricultural chemicals. Based on
ecological structure activity relationship (EcoSAR) analysis of test
data on analogous esters, EPA predicts toxicity to aquatic organisms
may occur at concentrations that exceed 90 parts per billion (ppb) of
the PMN substance in surface waters. As described in the PMN, releases
to surface water are not expected. Therefore, EPA has not determined
that the proposed manufacturing, processing, or use of the substance
may present an unreasonable risk. EPA has determined, however, that any
use of the substance resulting in surface water concentrations
exceeding 90 ppb may cause significant adverse environmental effects.
Based on this information, the PMN substance meets the concern criteria
at Sec.  721.170(b)(4)(ii).
    Recommended testing: EPA has determined that the results of a fish
acute toxicity test, freshwater and marine (OPPTS Test Guideline
850.1075); an aquatic invertebrate acute toxicity test, freshwater
daphnids (OPPTS Test Guideline 850.1010); and an algal toxicity test
(Office of Chemical Safety and Pollution Prevention (OCSPP) Test
Guideline 850.4500) would help characterize the environmental effects
of the PMN substance.
    CFR citation: 40 CFR 721.10637.

PMN Number P-02-167

    Chemical name: Lithium metal phosphate (generic).
    CAS number: Claimed as confidential.
    Basis for action: The PMN states that the generic (non-
confidential) use of the substance will be as an electrode material.
Based on EcoSAR analysis of test data on analogous inorganic
phosphates, EPA predicts toxicity to aquatic organisms may occur at
concentrations that exceed 1 ppb of the PMN substance in surface
waters. As described in the PMN, releases to water are not expected to
exceed 1 ppb. Therefore, EPA has not determined that the proposed
manufacturing, processing, or use of the substance presents an
unreasonable risk. EPA has determined, however, that any use of the
substance resulting in surface water concentrations exceeding 1 ppb may
cause significant adverse environmental effects. Based on this
information, the PMN substance meets the concern criteria at Sec.
721.170(b)(4)(ii).
    Recommended testing: EPA has determined that the results of a fish
acute toxicity test, freshwater and marine (OPPTS Test Guideline
850.1075); an aquatic invertebrate acute toxicity test, freshwater
daphnids (OPPTS Test Guideline 850.1010); and an algal toxicity test
(OCSPP Test Guideline 850.4500) would help characterize the
environmental effects of the PMN substance.
    CFR citation: 40 CFR 721.10638.

PMN Number P-02-668

    Chemical name: Siloxanes and Silicones, di-Me, polymers with Ph
silsesquioxanes, hydrolyzed, reaction products with 2-[[3-
(trimethoxysilyl)propoxy]methyl]oxirane.
    CAS number: 478823-10-8.
    Basis for action: The PMN substance will be used as a binder for
silicone coatings. Based on structure activity relationship (SAR)
analysis of test data on analogous epoxides and alkoxysilanes, EPA
identified concerns for mutagenicity, oncogenicity, reproductive
toxicity, developmental toxicity, lung toxicity, and sensitization from
dermal and inhalation exposures to the PMN substance. For the use
described in the PMN, significant occupational dermal and inhalation
exposures are not expected due to the use of impervious gloves and a
National Institute for Occupational Safety and Health (NIOSH)-certified
respirator with an assigned protection factor (APF) of at least 10, and
consumer exposures are not expected as the substance is not used in
consumer products. Therefore, EPA has not determined that
manufacturing, processing, and use of the substance may present an
unreasonable risk. EPA has determined, however, that use of the
substance without impervious gloves where there is a potential for
dermal exposure; any use of the substance without a NIOSH-certified
respirator with an APF of at least 10; or any use of the substance in
consumer products may result in serious health effects. Based on this
information, the PMN substance meets the concern criteria at Sec.
721.170 (b)(1)(i)(C) and (b)(3)(ii).
    Recommended testing: EPA has determined that the results of a 90-
day inhalation toxicity test (OPPTS Test Guideline 870.3465), with
attention to the pathology of the reproductive organs, and a
carcinogenicity test (OPPTS Test Guideline 870.4200) would help to
characterize the human health effects of the PMN substance.
    CFR citation: 40 CFR 721.10639.

PMN Number P-03-135

    Chemical name: 1,2-Cyclohexanedicarboxylic acid, 1-(2-ethylhexyl)
2-(2-methylpropyl) ester.
    CAS number: 252958-29-5.
    Basis for action: The PMN states that the generic (non-
confidential) use of the substance will be as a compressor lubricant.
Based on EcoSAR analysis of test data on analogous esters, EPA predicts
toxicity to aquatic organisms may occur at concentrations that exceed 1
ppb of the PMN substance in surface waters. As described in the PMN,
the substance is not released to surface waters. Therefore, EPA has not
determined that the proposed manufacturing, processing, or use of the
substance may present an unreasonable risk. EPA has determined,
however, that any use of the substance resulting in surface water
concentrations exceeding 1 ppb may cause significant adverse
environmental effects. There are two other chemical substances
identified in the PMN that are already on the TSCA Inventory. The SNUR
does not apply to those chemical substances. Based on this information,
the PMN substance meets the concern criteria at Sec.
721.170(b)(4)(ii).
    Recommended testing: EPA has determined that the results of a fish
early-life stage toxicity test (OPPTS Test Guideline 850.1400); a
daphnid chronic toxicity test (OPPTS Test Guideline 850.1300); and an
algal toxicity test (OCSPP Test Guideline 850.4500) would help to
characterize the environmental effects of the PMN substance.
    CFR citation: 40 CFR 721.10640.

PMN Number P-03-255

    Chemical name: Phenol and vinyltoluene based hydrocarbon resin
(generic).
    CAS number: Claimed as confidential.
    Basis for action: The PMN states that the generic (non-
confidential) use of the substance will be as a diluent for coatings.
Based on EcoSAR analysis of test data on analogous neutral organics,
EPA predicts toxicity to aquatic organisms may occur at concentrations
that exceed 1 ppb of the PMN substance in surface waters. As described
in the PMN, releases to water are not expected. Therefore, EPA has not
determined that the proposed manufacturing, processing, or use of the
substance may present an unreasonable risk. EPA has determined,
however, that any use of the substance resulting in surface water
concentrations exceeding 1 ppb may cause significant adverse
environmental effects. Based on this information, the PMN substance
meets the concern criteria at Sec.  721.170(b)(4)(ii).

    Recommended testing: EPA has determined that the results of a fish
early-life stage toxicity test (OPPTS Test Guideline 850.1400); a
daphnid chronic toxicity test (OPPTS Test Guideline 850.1300); and an
algal toxicity test (OCSPP Test Guideline 850.4500) would help to
characterize the environmental effects of the PMN substance.
    CFR citation: 40 CFR 721.10641.

PMN Numbers P-03-762 and P-03-763

    Chemical name: Modified polyisocyanates (generic).
    CAS number: Claimed as confidential.
    Basis for action: The consolidated PMN states that the generic
(non-confidential) use of the substances will be as hardeners. Based on
SAR analysis of test data on analogous isocyanates, EPA has identified
concerns for sensitization and irritation from dermal and inhalation
exposure to the PMN substances. For the use described in the PMN,
significant occupational inhalation and dermal exposures are not
expected due to no domestic manufacture, use of impervious gloves, and
no use of the substances involving an application method that generates
a vapor, mist, or aerosol. Further, consumer exposures are not expected
as the substance is not used in consumer products. Therefore, EPA has
not determined that the proposed processing or use of the substances
may present an unreasonable risk. EPA has determined, however, that any
domestic manufacture of the substances; any use of the substances
without impervious gloves where there is a potential for dermal
exposures; any use of the substance in consumer products; or any use of
the substances involving an application method that generates a vapor,
mist, or aerosol may result in serious health effects. Based on this
information, the PMN substances meet the concern criteria at Sec.
721.170(b)(3)(ii).
    Recommended testing: EPA has determined that the results of a skin
sensitization test (OPPTS Test Guideline 870.2600) and a 90-day
inhalation toxicity test (OPPTS Test Guideline 870.3465) would help
characterize the human health effects of the PMN substances.
    CFR citation: 40 CFR 721.10642.

PMN Number P-04-640

    Chemical name: Diisocyanate terminated polycarbodiimide (generic).
    CAS number: Claimed as confidential.
    Effective date of TSCA section 5(e) consent order: February 1,
2006.
    Basis for TSCA section 5(e) consent order: The PMN states that the
generic (non-confidential) use of the substance will be as a
crosslinking agent for solvent-based inks; a monomer for
polymerization; and a water scavenger for producing anhydrous polymers.
The PMN did not identify consumer uses for the PMN substance. Based on
SAR analysis of test data on structurally similar diisocyanates, EPA
identified concerns for dermal sensitization, respiratory
sensitization, and pulmonary toxicity from exposure to the PMN
substance by the inhalation and dermal routes. The order was issued
under sections 5(e)(1)(A)(i) and 5(e)(1)(A)(ii)(I) of TSCA based on a
finding that this substance may present an unreasonable risk of injury
to human health. To protect against these risks, the order requires:
    1. Use of personal protective equipment including impervious gloves
(when there is potential dermal exposure) and either a NIOSH-certified
respirator with an APF of at least 2,000, or compliance with a NCEL of
0.05 mg/m\3\ as an 8-hour time-weighted average (when there is
potential inhalation exposure).
    2. Establishment and use of a hazard communication program. The
SNUR would designate as a ``significant new use'' the absence of these
protective measures and consumer use of the PMN substance.
    Recommended testing: EPA has determined that data from worker
exposure to the PMN substance (such as inhalation monitoring data
generated according to the NCELs section of the consent order) or a 90-
day inhalation toxicity test (OPPTS Test Guideline 870.3465) would help
characterize the human health effects of the PMN substance. The order
does not require submission of the testing at any specified time or
production volume. However, the order's restrictions on manufacture,
import, processing, distribution in commerce, use, and disposal of the
PMN substance will remain in effect until the order is modified or
revoked by EPA based on submission of that or other relevant
information.
    CFR citation: 40 CFR 721.10643.

PMN Number P-07-553

    Chemical name: Reaction product of aluminum hydroxide and modified
alkoxysilane (generic).
    CAS number: Claimed as confidential.
    Basis for action: The PMN states that the substance will be used as
a flame retardant. Based on SAR analysis of test data on analogous
respirable, poorly soluble particulates, EPA identified concerns for
lung toxicity from inhalation exposures to the PMN substance. At an
annual production volume of 100,000 kilograms (kgs), significant
occupational inhalation exposures are not expected due to the use of a
NIOSH-certified respirator with an APF of at least 10. Therefore, EPA
has not determined that the proposed manufacturing, processing, or use
of the substance may present an unreasonable risk. EPA has determined,
however, that any use of the substance without a NIOSH-certified
respirator with an APF of at least 10, where there is a potential for
inhalation exposure; or any increase of the annual 100,000 kg
production volume may result in increased exposure to the PMN
substance, which may cause serious human health effects. Based on this
information, the PMN substance meets the concern criteria at Sec.
721.170(b)(3)(ii).
    Recommended testing: EPA has determined that the results of a 90-
day inhalation toxicity test (OPPTS Test Guideline 870.3465) with a 60-
day holding period would help characterize the health effects of the
PMN substance.

PMN Number P-08-392

    Chemical name: Multi-walled carbon nanotube (generic) (P-08-392).
    CAS number: Claimed as confidential.
    Effective date of TSCA section 5(e) consent order: November 14,
2008.
    Basis for TSCA section 5(e) consent order: The PMN states that the
generic (non-confidential) use of the substance will be as an
antistatic, reinforcement additive. Based on test data on the PMN
substance, and SAR analysis of test data on structurally similar
respirable, poorly soluble particulates, EPA identified concerns for
pulmonary toxicity, fibrosis, carcinogenicity, mutagenicity, and
immunotoxicity. The order was issued under sections 5(e)(1)(A)(i) and
5(e)(1)(A)(ii)(I) of TSCA, based on a finding that the PMN substance
may present an unreasonable risk of injury to human health. To protect
against these risks, the order:
    1. Requires use of personal protective equipment including
impervious gloves and protective clothing (when there is a potential
dermal exposure) and a NIOSH-certified air-purifying, tight-fitting
full-face respirator equipped with N100 filters with an APF of at least
50 (when there is potential inhalation exposure).
    2. Prohibits manufacture of the PMN substance in the United States.
    3. Restricts processing and use of the PMN substance to those uses
specified in the consent order.
    The SNUR would designate as a ``significant new use'' the absence
of these protective measures.

    Recommended testing: EPA has determined that the results of a 90-
day inhalation toxicity test (OPPTS Test Guideline 870.3465 or
Organisation for Economic Co-operation and Development (OECD) Test
Guideline 413) in rats with a post exposure observation period of up to
3 months, including bronchoalveolar lavage fluid (BALF) analysis and
certain material characterization data, would help characterize
possible effects of the substance. In the consent order, the PMN
submitter has agreed to perform these tests within 18 months of
commencing non-exempt commercial manufacture.
    CFR citation: 40 CFR 721.10645.

PMN Number P-09-257

    Chemical name: Multi-walled carbon nanotube (generic) (P-09-257).
    CAS number: Claimed as confidential.
    Effective date of TSCA section 5(e) consent order: August 11, 2009.
    Basis for TSCA section 5(e) consent order: The PMN states that the
generic (non-confidential) uses of the substance will be as an electric
conductive filler to replace conventional material such as carbon black
or carbon fiber in matrixes such as polymer resin for conductive
applications, and an additive for elastomers, polymers, and resins to
enhance mechanical properties. Based on SAR analysis of test data on
analogous respirable, poorly soluble particulates and other CNTs, EPA
identified concerns for pulmonary toxicity, fibrosis, carcinogenicity,
mutagenicity, and immunotoxicity. Further, available data suggests that
pulmonary deposition of some nanoparticles, including CNTs, may induce
cardiovascular toxicity if inhaled. Although there are no environmental
toxicity studies on CNTs available, EPA expects that some fraction of
the CNTs, if released into the environment, will eventually be
suspended in water. There have been sublethal effects observed for
single walled CNTs in rainbow trout at levels as low as 100 ppb. The
order was issued under section 5(e)(1)(A)(i) and (e)(1)(A)(ii)(I) of
TSCA based on a finding that this substance may present an unreasonable
risk of injury to human health and the environment. To protect against
these risks, the order:
    1. Requires use of personal protective equipment including
impervious gloves and protective clothing (when there is a potential
dermal exposure) and a NIOSH-certified air-purifying, tight-fitting
full-face respirator equipped with N100 filters with an APF of at least
50 (when there is potential inhalation exposure).
    2. Prohibits manufacture of the PMN substance in the United States.
    3. Restricts processing and use of the PMN substance to those uses
specified in the consent order.
    4. Prohibits release to water during processing and use.
    The SNUR would designate as a ``significant new use'' the absence
of these protective measures.
    Recommended testing: EPA has determined that the results of a 90-
day inhalation toxicity test (OPPTS Test Guideline 870.3465 or OECD
Test Guideline 413) in rats with a post exposure observation period of
up to 3 months (including BALF analysis, a determination of
cardiovascular toxicity (clinically-based blood/plasma protein
analyses), and histopathology of the heart) and development of data on
certain physical/chemical properties would help characterize possible
effects of the substance. In the consent order, the PMN submitter has
agreed not to exceed a specified production volume/time limit
(whichever comes first) without performing the 90-day test on the PMN
substance. In addition, in the consent order, the PMN submitter agreed
to provide the physical/chemical properties data within a specified
time limit.

    Chemical name: Multi-walled carbon nanofibers (generic).
    CAS number: Claimed as confidential.
    Effective date of TSCA section 5(e) consent order: May 9, 2011.
    Basis for TSCA section 5(e) consent order: The PMNs state that the
uses of the substances will be as electrical and thermal conductivity
additives, mechanical reinforcement additives, energy storage
additives, and chemical intermediates. Based on SAR analysis of test
data on analogous respirable, poorly soluble particulates and other
CNTs, EPA identified concerns for pulmonary toxicity, fibrosis,
carcinogenicity, mutagenicity, and immunotoxicity. Further, available
data suggests that pulmonary deposition of some nanoparticles,
including CNTs may induce cardiovascular toxicity if inhaled. Although
there are no environmental toxicity studies on CNTs available, EPA
expects that some fraction of the CNTs, if released into the

5(e)(1)(A)(i) and 5(e)(1)(A)(ii)(I) of TSCA based on a finding that
these substances may present an unreasonable risk of injury to human
health and the environment. To protect against this risk, the order:
    1. Requires use of personal protective equipment including

full-face respirator equipped with N100 filters with an APF of at least
50 (when there is potential inhalation exposure).
    2. Restricts use of the PMN substances to use only as electrical
and thermal conductivity additives, mechanical reinforcement additives,
energy storage additives, and chemical intermediates as specified in
the consent order.
    3. Restricts processing and use of the PMN substances to industrial
settings.
    4. Prohibits release of the PMN substances into the waters of the
United States during processing and use activities.
    The SNUR would designate as a ``significant new use'' the absence
of these protective measures.
    Recommended testing: EPA has determined that the results of certain
physical/chemical properties data, workplace exposure monitoring and
characterization testing, and a 90-day inhalation toxicity test (OPPTS
Test Guideline 870.3465 or OECD Test Guideline 413) in rats would help
characterize the human health effects of the PMN substances. The PMN
submitter agreed to provide the physical/chemical properties data for
the PMN substances within one year after submitting the notice of
commencement. The consent order contains two additional production
volume limits. The PMN submitter agreed not to exceed the first
production volume limit without submitting workplace exposure
monitoring and characterization testing (including byproducts) as well
as quantification and characterization of substances that may be
released during exposures typical during the use phase, such as
handling, tearing and cutting the PMN substances. The PMN submitter has
also agreed not to exceed the second production volume limit without
performing two 90-day inhalation toxicity tests, with a post-exposure
observation period of up to 3 months, BALF analysis, aggregation/
agglomeration state, shape, size/size particle distribution and surface
properties of materials as administered, aggregation/agglomeration
state, shape, size/size particle distribution and surface properties of
materials of the

delivered materials after administration, determination of
cardiovascular toxicity, heart histopathology, and data on pulmonary
deposition. One 90-day inhalation toxicity test will be conducted from
a representative PMN substance in the group P-10-115, P-10-116, P-10-
117, P-10-118, P-10-119, and the other 90-day inhalation toxicity test
will be conducted from a representative PMN substance in the group P-
10-120, P-10-121, P-10-122, P-10-123, P-10-124, P-10-125, and P-10-126.

PMN Numbers P-10-545 and P-10-546

    Chemical name: Modified lithium iron phosphates (generic).
    CAS number: Claimed as confidential.
    Effective date of TSCA section 5(e) consent order: December 10,
2010.
    Basis for TSCA section 5(e) consent order: The consolidated PMN
states that the generic (non-confidential) use of the substances will
be as battery electrode components, contained use. Based on test data
on analogous respirable, poorly soluble particulates, there is
potential risk for adverse lung effects including cancer, lung
fibrosis, lung inflammation and systemic effects, including
immunotoxicity. EPA has identified concerns for these health effects
from exposures to the PMN substances. Based on EcoSAR analysis of test
data on analogous phosphates, EPA predicts toxicity to aquatic
organisms may occur at concentrations that exceed 2 ppb of the PMN
substance in surface waters. The order was issued under sections
5(e)(1)(A)(i) and 5(e)(1)(A)(ii)(I) of TSCA based on a finding that
these substances may present an unreasonable risk of injury to human
health or the environment. To protect against these risks, the consent
order:
    1. Restricts manufacturing, processing, and use of the substances
to a fully-enclosed and automated process, including all loading and
unloading activities.
    2. Restricts use of the PMN substances to use only as specified in
the consent order.
    3. Prohibits release of the PMN substances into the waters of the
United States during processing and use activities.
    The SNUR would designate as a ``significant new use'' the absence
of these protective measures.
    Recommended testing: EPA has determined that the results of a 90-
day inhalation toxicity test (OPPTS Test Guideline 870.3465) in rats
with a post-exposure observation period of up to 3 months, including
BALF analysis; an algal toxicity test (OCSPP Test Guideline 850.5400);
and physical/chemical properties testing for: Water solubility (OECD
Test Guideline 105); surface chemistry, particle size distribution of
the PMN substances, dustiness test (European Standard 15051); and
particle size distribution, aggregation state, and porosity would help
characterize the human health and environmental effects of the PMN
substances. The PMN submitter has agreed not to exceed the confidential
production volume in the consent order without performing the 90-day
inhalation toxicity test and the physical/chemical properties tests.
    CFR citation: 40 CFR 721.10648.

PMN Number P-11-115

    Chemical name: MDI modified polyalkylene glycol adipate polyester
(generic).
    CAS number: Claimed as confidential.
    Basis for action: The PMN states that the generic (non-
confidential) use of the substance will be as an adhesive. Based on SAR
analysis of test data on analogous diisocyanates, EPA identified
concerns for respiratory and dermal sensitization. For the use
described in the PMN, significant occupational dermal and inhalation
exposures are not expected due to the use of a NIOSH-certified
respirator with an APF of at least 10, and consumer exposures are not
expected as the substance is not used in consumer products. Therefore,
EPA has not determined that the proposed manufacturing, processing, or
use of the substance may present an unreasonable risk. EPA has
determined, however, that any use of the substance without a NIOSH-
certified respirator with an APF of at least 10, where there is a
potential for inhalation exposures, or any use of the substance in
consumer products may cause serious health effects. Based on this
information, the PMN substance meets the concern criteria at Sec.
721.170(b)(3)(ii).
    Recommended testing: EPA has determined that the results of a skin
sensitization test (OPPTS Test Guideline 870.2600) and a 90-day
inhalation toxicity test (OPPTS Test Guideline 870.3465) would help
characterize the human health effects of the PMN substance.
    CFR citation: 40 CFR 721.10649.

PMN Number P-11-155

    Chemical name: Polyether substituted anthraquinone derivative
(generic).
    CAS number: Claimed as confidential.
    Basis for action: The PMN states that the generic (non-
confidential) use of the substance will be used as a colorant for
cleaners and detergents. Based on EcoSAR analysis of test data on
analogous aromatic amines and nonionic dyes, EPA predicts toxicity to
aquatic organisms may occur at concentrations that exceed 2 ppb of the
PMN substance in surface waters for greater than 20 days per year. This
20-day criterion is derived from partial life cycle tests (daphnid
chronic and fish early life stage tests) that typically range from 21
to 28 days in duration. EPA predicts toxicity to aquatic organisms may
occur if releases of the PMN substance to surface water, from uses
other than as described in the PMN, exceed releases from the use
described in the PMN. For the use described in the PMN, environmental
releases did not exceed 1 ppb for more than 20 days per year.
    Therefore, EPA has not determined that the proposed manufacturing,
processing, or use of the substance may present an unreasonable risk.
EPA has determined, however, that any use of the substance other than
as a colorant for cleaners and detergents may cause significant adverse
environmental effects. Based on this information, the PMN substance
meets the concern criteria at Sec.  721.170(b)(4)(ii).
    Recommended testing: EPA has determined that the results of a fish
acute toxicity test, freshwater and marine (OPPTS Test Guideline
850.1075) and an aquatic invertebrate acute toxicity test, freshwater
daphnids (OPPTS Test Guideline 850.1010) would help characterize the
environmental effects of the PMN substance.

PMN Number P-11-290

    Chemical name: Carbide derived nanocarbon (generic).
    CAS number: Claimed as confidential.
    Basis for action: The PMN states that the generic (non-
confidential) use of the substance will be as a sensor element in an
electrochemical sensor. Based on SAR analysis of test data on
respirable, poorly soluble particulates, EPA identified concerns for
pulmonary toxicity, fibrosis, carcinogenicity, mutagenicity, and
immunotoxicity if the substances were manufactured by a method other
than described in the PMN. Further, available data suggests that
pulmonary deposition of some carbon-based nanoparticles, may induce
cardiovascular toxicity if inhaled. EPA identified concerns for lung
toxicity to workers from inhalation exposures to the PMN substance. For
the manufacture method described in the PMN, significant dermal and
inhalation exposures are not expected. Therefore, EPA has not
determined that the proposed manufacturing, processing, or use of the
substance may present an

unreasonable risk. EPA has determined, however, that manufacture of the
substance by a method other than as described in the PMN may cause
serious health effects. Based on this information, the PMN substance
meets the concern criteria at Sec.  721.170(b)(3)(ii).
    Recommended testing: EPA has determined that inhalation monitoring
data collected during the manufacturing process according to the EPA
draft Inhalation Monitoring Data Collection Guidelines (located in the
docket under docket ID number EPA-HQ-OPPT-2012-0727) would help
characterize the human health effects of the PMN substance.

    CAS numbers: Claimed as confidential.
    Basis for action: The PMNs state that the generic (non-
confidential) use of the substances will be as industrial adhesives.
Based on SAR analysis of test data on analogous isocyanates, EPA
identified concerns for sensitization from dermal and inhalation
exposure to the PMN substances. For the use described in the PMNs,
significant occupational dermal and inhalation exposures are not
expected due to the use of a NIOSH-certified respirator with an APF of
at least 10, and consumer exposures are not expected. Therefore, EPA
has not determined that the proposed manufacturing, processing, or use

    CAS number: 1313708-90-5.
    Basis for action: The PMN states that the substance will be used as
a coating for wind craft wings. Based on SAR analysis of test data on
structurally similar chemicals submitted under TSCA section 8(e), EPA
identified concerns for oncogenicity and mutagenicity. Additionally,
based on the isocyanate moiety, the Agency identified concerns for
sensitization. For the use described in the PMN, significant
occupational inhalation exposures are not expected due to the use of a
NIOSH-certified respirator with an APF of at least 10, and consumer
exposures are not expected as the substance is not used in consumer
products. Therefore, EPA has not determined that the proposed

alkyl silane (generic).
    CAS number: Claimed as confidential.
    Basis for action: The PMN states that the generic (non-
confidential) use of the substance will be as an adhesive. Based on SAR
analysis of test data on analogous isocyanates, EPA identified concern
for sensitization from dermal and inhalation exposure to the PMN
substance. Additionally, liquid and vapor contact with the eye can
cause moderate to severe irritation. For the use described in the PMN,
significant occupational dermal and inhalation exposures are not
expected due to the use of a NIOSH-certified respirator with an APF of
at least 10, and consumer exposures are not expected as the substance
is not used in consumer products. Therefore, EPA has not determined

V. Rationale and Objectives of the Proposed Rule

A. Rationale

    During review of the PMNs submitted for the chemical substances
that are subject to these proposed SNURs, EPA concluded that for 17 of
the 37 chemical substances regulation was warranted under TSCA section
5(e) pending the development of information sufficient to make reasoned
evaluations of the health or environmental effects of the chemical
substances. The basis for such findings is outlined in Unit IV. Based
on these findings, TSCA section 5(e) consent orders requiring the use
of appropriate exposure controls were negotiated with the PMN
submitters. The proposed SNUR provisions for these chemical substances
are consistent with the provisions of the TSCA section 5(e) consent
orders. These SNURs are being proposed pursuant to Sec.
[emsp14]721.160.
    In the other 20 cases, where the uses are not regulated under a
TSCA section 5(e) consent order, EPA determined that one or more of the
criteria of concern established at Sec.  [emsp14]721.170 were met, as
discussed in Unit IV.

B. Objectives

    EPA is proposing these SNURs for specific chemical substances which
have undergone premanufacture review because the Agency wants to
achieve the following objectives with regard to the significant new
uses designated in this proposed rule:
     EPA would receive notice of any person's intent to
manufacture, import, or process a listed chemical substance for the
described significant new use before that activity begins.
     EPA would have an opportunity to review and evaluate data
submitted in a SNUN before the notice submitter begins manufacturing,
importing, or processing a listed chemical substance for the described
significant new use.
     EPA would be able to regulate prospective manufacturers,
importers, or processors of a listed chemical substance before the
described significant new use of that chemical substance occurs,
provided that regulation is warranted pursuant to TSCA sections 5(e),
5(f), 6, or 7.
     EPA would ensure that all manufacturers, importers, and
processors of the same chemical substance that is subject to a TSCA
section 5(e) consent order are subject to similar requirements.
    Issuance of a SNUR for a chemical substance does not signify that
the chemical substance is listed on the TSCA Chemical Substance
Inventory (TSCA Inventory). Guidance on how to determine if a chemical
substance is on the TSCA Inventory is available on the Internet at
http://www.epa.gov/opptintr/existingchemicals/pubs/tscainventory/index.html.

VI. Notice and Comment Procedures

    EPA is issuing these SNURs by notice and comment procedure, as
described in Sec.  [emsp14]721.170(d)(4). In accordance with Sec.
[emsp14]721.170(d)(4)(ii)(A), persons are being given the opportunity
to submit comments on or before April 26, 2013 on whether EPA should
establish notification requirements.

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

    To establish a significant ``new'' use, EPA must determine that the
use is not ongoing. The chemical substances subject to this proposed
rule have undergone premanufacture review. TSCA section 5(e) consent
orders have been issued for 17 chemical substances and the PMN
submitters are prohibited by the TSCA section 5(e) consent orders from
undertaking activities which EPA is designating as significant new
uses. EPA is soliciting comments on whether any of the uses proposed as
significant new uses are ongoing.
    As discussed in the Federal Register of April 24, 1990 SNUR, EPA
has decided 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 date of
publication of this 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 significant new use before the rule became
final, and then argue that the use was ongoing before the effective
date of the final rule. Thus, persons who begin commercial manufacture,
import, or processing of the chemical substances that would be
regulated through these proposed SNURs will have to cease any such
activity before the effective date of the rule if and when finalized.
To resume their activities, these persons would have to comply with all
applicable SNUR notice requirements and wait until the notice review
period, including any extensions, expires.
    EPA has promulgated provisions to allow persons to comply with
these proposed SNURs before the effective date. If a person meets the
conditions of advance compliance under Sec.  [emsp14]721.45(h), the
person would be considered exempt from the requirements of the SNUR.

VIII. Test Data and Other Information

    EPA recognizes that TSCA section 5 does not require developing any
particular test data before submission of a SNUN. The two exceptions
are:
    1. Development of test data is required where the chemical
substance subject to the SNUR is also subject to a test rule under TSCA
section 4 (see TSCA section 5(b)(1)).
    2. Development of test data may be necessary where the chemical
substance has been listed under TSCA section 5(b)(4) (see TSCA section
5(b)(2)).
    In the absence of a TSCA section 4 test rule or a TSCA section
5(b)(4) listing covering the chemical substance, 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 (see 40 CFR
720.50). However, upon review of PMNs and SNUNs, the Agency has the
authority to require appropriate testing. In cases where EPA issued a
TSCA section 5(e) consent order that requires or recommends certain
testing, Unit IV. lists those tests. Unit IV. also lists recommended
testing for non-5(e) SNURs. Descriptions of tests are provided for
informational purposes. EPA strongly encourages persons, before
performing any testing, to consult with the Agency pertaining to
protocol selection. To access the OCSPP test guidelines referenced in
this document electronically, please go to http://www.epa.gov/ocspp and
select ``Test Methods and Guidelines.'' The Organisation for Economic
Co-operation and Development (OECD) test guidelines are available from
the OECD Bookshop at http://www.oecdbookshop.org or Source OECD at
http://www.sourceoecd.org. To access the European Standard, EN 15051
method, issued by The European Committee for Standardization (CEN),
please go to http://www.cen.eu/cen/products.
    In the TSCA section 5(e) consent orders for several of the chemical
substances regulated under this proposed rule, EPA has established
production volume limits in view of the lack of data on the potential
health and environmental risks that may be posed by the significant new
uses or increased exposure to the chemical substances. These limits
cannot be exceeded unless the PMN submitter first submits the results
of toxicity tests that would permit a reasoned evaluation of the
potential risks posed by these chemical substances. Listings of the
tests specified in the TSCA section 5(e) consent orders are included in
Unit IV. The SNURs contain the same production volume limits as the
TSCA section 5(e) consent orders. Exceeding these production limits is
defined as a significant new use. Persons who intend to exceed the
production limit must notify the Agency by submitting a SNUN at least
90 days in advance of commencement of non-exempt commercial
manufacture, import, or processing.
    When physical/chemical properties of test material and/or material
characterization tests are recommended for nanoscale substances that
are the subject of this proposed rule, you should take into
consideration the characterizations identified in the Guidance Manual
for the Testing of Manufactured Nanomaterials: OECD's Sponsorship
Programme, which is available at http://www.oecd.org/officialdocuments/displaydocumentpdf/?cote=env/jm/mono(2009)20/rev&doclanguage=en.
    The recommended tests specified in Unit IV. may not be the only
means of addressing the potential risks of the chemical substance.
However, submitting a SNUN without any test data may increase the
likelihood that EPA will take action under TSCA section 5(e),
particularly if satisfactory test results have not been obtained from a
prior PMN or SNUN submitter. EPA recommends that potential SNUN
submitters contact EPA early enough so that they will be able to
conduct the appropriate tests.
    SNUN submitters should be aware that EPA will be better able to
evaluate SNUNs which provide detailed information on the following:
     Human exposure and environmental release that may result
from the significant new use of the chemical substances.
     Potential benefits of the chemical substances.
     Information on risks posed by the chemical substances
compared to risks posed by potential substitutes.

IX. SNUN Submissions

    According to Sec.  [emsp14]721.1(c), persons submitting a SNUN must
comply with the same notification requirements and EPA regulatory
procedures as persons submitting a PMN, including submission of test
data on health and environmental effects as described in 40 CFR 720.50.
SNUNs must be submitted on EPA Form No. 7710-25, generated using e-PMN
software, and submitted to the Agency in accordance with the procedures
set forth in 40 CFR 720.40 and Sec.  721.25. E-PMN software is
available electronically at http://www.epa.gov/opptintr/newchems.

X. Economic Analysis

    EPA has evaluated the potential costs of establishing SNUN
requirements for potential manufacturers, importers, and processors of
the chemical substances subject to this proposed rule. EPA's complete
economic analysis is available in the docket under docket ID number
EPA-HQ-OPPT-2012-0727.

XI. Statutory and Executive Order Reviews

A. Executive Order 12866

    This proposed rule would establish SNURs for several new chemical
substances that were the subject of PMNs, and, in some cases, TSCA
section 5(e) consent orders. The Office of Management and Budget (OMB)
has exempted these types of actions from review under Executive Order
12866, entitled ``Regulatory Planning and Review'' (58 FR 51735,
October 4, 1993).

B. Paperwork Reduction Act (PRA)

    According to 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 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. EPA would amend the table in 40 CFR part 9 to list the OMB
approval number for the information collection requirements contained
in this proposed rule, if the SNUR is subsequently issued as a final
rule. This listing of the OMB control numbers and their subsequent
codification in the CFR satisfies the display requirements of PRA and
OMB's implementing regulations at 5 CFR part 1320. This Information
Collection Request (ICR) was previously subject to public notice and
comment prior to OMB approval, and given the technical nature of the
table, EPA finds that further notice and comment to amend it is
unnecessary. As a result, EPA finds that there is ``good cause'' under
section 553(b)(3)(B) of the Administrative Procedure Act (5 U.S.C.
553(b)(3)(B)) to amend this table without further notice and comment.
    The information collection requirements related to this action have
already been approved by OMB pursuant to PRA under OMB control number
2070-0012 (EPA ICR No. 574). This action would not impose any burden
requiring additional OMB approval. If an entity were to submit a

SNUN to the Agency, the annual burden is estimated to average between
30 and 170 hours per response. 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 (RFA)

    On February 18, 2012, EPA certified pursuant to RFA section 605(b)
(5 U.S.C. 601 et seq.), that promulgation of these SNURS would not have
a significant economic impact on a substantial number of small entities
where the following are true:
    1. A significant number of SNUNs would not be submitted by small
entities in response to the SNUR.
    2. The SNUR submitted by any small entity would not cost
significantly more than $8,300.
    A copy of that certification is available in the docket for this
proposed rule.
    This proposed rule is within the scope of the February 18, 2012
certification. Based on the Economic Analysis discussed in Unit X. and
EPA's experience promulgating SNURs (discussed in the certification),
EPA believes that the following are true:
     A significant number of SNUNs would not be submitted by
small entities in response to the SNUR.
     Submission of the SNUN would not cost any small entity
significantly more than $8,300.
    Therefore, the promulgation of the SNUR would not have a
significant economic impact on a substantial number of small entities.

D. Unfunded Mandates Reform Act (UMRA)

    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 reasons to believe that any
State, local, or Tribal government would be impacted by this proposed
rule. As such, EPA has determined that this proposed rule would not
impose any enforceable duty, contain any unfunded mandate, or otherwise
have any effect on small governments subject to the requirements of
UMRA sections 202, 203, 204, or 205 (2 U.S.C. 1501 et seq.).

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 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 nor 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 9,
2000), do not apply to this proposed 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 action 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 and because this action is not a significant regulatory action
under Executive Order 12866.

I. National Technology Transfer and Advancement Act (NTTAA)

    In addition, since this action does not involve any technical
standards, NTTAA 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).
