SUPPLEMENTARY INFORMATION:

I. Does this action apply to me?

    You may be potentially affected by this action if you manufacture, 
process, or use the chemical substance Pentane, 1,1,1,2,3,3-hexafluoro-
4-(1,1,2,3,3,3-hexafluoropropoxy)- (PMN P-07-204; CAS No. 870778-34-0) 
contained in this final rule. The following list of North American 
Industrial 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 or processors of the subject chemical 
substance (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 
and 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 these SNURs 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 this final rule 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.

II. Background

A. What action is the agency taking?

    EPA is finalizing a SNUR, under TSCA section 5(a)(2), for the 
chemical substance Pentane, 1,1,1,2,3,3-hexafluoro-4-(1,1,2,3,3,3-
hexafluoropropoxy)- (PMN P-07-204; CAS No. 870778-34-0) codified at 40 
CFR 721.10509. This final rule requires persons who intend to 
manufacture or process the chemical substance for an activity that is 
designated as a significant new use by this final rule to notify EPA at 
least 90 days before commencing that activity.
    In the Federal Register of September 21, 2012 (77 FR 58666) (FRL-
9357-2), EPA issued a direct final SNUR for the chemical substance. EPA 
received notice of intent to submit adverse comments for the direct 
final SNUR. In response to that notification a rule was proposed in the 
Federal Register issue of January 23, 2013 (78 FR 4806) (FRL-6369-9). 
In response to the proposed rule, EPA received one public comment from 
the submitter of PMN P-07-204.
    The comment noted that in the time period between filing of a 
Notice of Commencement of Manufacture or Import in March 2008, and the 
time of publication of the direct final SNUR in September 2012, the 
company had entered into an industrial solvent use that did not 
specifically fall within the scope of the 40 CFR 721.80(j) (the 
confidential uses identified in the amended premanufacture notice) 
significant new use reporting requirement contained in the rule. 
Therefore, the use was considered an ongoing use at the time of the 
direct final SNUR.
    Further, the commenter mentioned the intent to submit several 
health and safety studies on the PMN substance that were completed 
after the expiration of the PMN review period. The following table 
identifies the studies that were subsequently submitted to the Agency 
for review and the results of EPA's review of those studies:

[[Page 12085]]

    Agency review of the 29-day inhalation toxicity study, which 
demonstrated liver effects, along with the perfluorochemical analog 
data cited in the proposed SNUR, demonstrate the concern cited in the 
proposed SNUR for neurotoxicity and liver effects as a result of 
unprotected occupational exposures via the dermal route. Therefore, the 
Agency is issuing a final SNUR as proposed that designates as a 
significant new use manufacture or processing of the substance without 
impervious gloves, where there is a potential for dermal exposure, and 
simplifies the wording in the significant new use designation under 40 
CFR 721.80 to encompass the ongoing use as follows: ``A significant new 
use is any use of the substance other than for the specific 
confidential industrial solvent uses identified in the amended 
premanufacture notice (PMN).''

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 
or process the chemical substance for that use. Persons who must report 
are described in Sec.  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 final 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.  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), (2), (3), and (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. Rationale and Objectives of the Final Rule

A. Rationale

    During review of the PMN for the chemical substance Pentane, 
1,1,1,2,3,3-hexafluoro-4-(1,1,2,3,3,3-hexafluoropropoxy)- (PMN P-07-
204; CAS No. 870778-34-0), EPA determined that one or more of the 
criteria of concern established at Sec.  721.170 were met. For 
additional discussion of the rationale for the SNUR on this chemical, 
see Units II., IV., and V. of the proposed rule.

B. Objectives

    EPA is issuing this final SNUR for the chemical substance Pentane, 
1,1,1,2,3,3-hexafluoro-4-(1,1,2,3,3,3-hexafluoropropoxy)- (PMN P-07-
204; CAS N. 870778-34-0) because the Agency wants to achieve the 
following objectives with regard to the significant new uses designated 
in this final rule:
     EPA will receive notice of any person's intent to 
manufacture or process a listed chemical substance 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 manufacturing or 
processing a listed chemical substance for the described significant 
new use.
     EPA will be able to regulate prospective manufacturers 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.
    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.

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 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 
chemical substance pentane, 1,1,1,2,3,3-hexafluoro-4-(1,1,2,3,3,3-
hexafluoropropoxy)- (PMN P-07-204; CAS No. 870778-34-0), EPA considered 
relevant information about the toxicity of the chemical substances, 
likely human exposures and environmental releases associated with 
possible uses, and the four bulleted TSCA section 5(a)(2) factors 
listed in this unit.

V. Applicability of the Significant New Use Designation

    If uses begun after the proposed rule was published were considered 
ongoing rather than new, any person could defeat the SNUR by initiating 
the significant new use before the final rule was issued. Therefore EPA 
has designated the date of publication of the proposed rule as the 
cutoff date for determining whether the new use is ongoing. Consult the 
Federal Register Notice of April 24, 1990 (55 FR 17376, FRL 3658-5) for 
a more detailed discussion of the cutoff date for ongoing uses.
    Any person who began commercial manufacture or processing of the 
chemical substance identified as pentane, 1,1,1,2,3,3-hexafluoro-4-
(1,1,2,3,3,3-hexafluoropropoxy)- (PMN P-07-204; CAS No. 870778-34-0) 
for any of the significant new uses designated in the proposed SNUR 
after the date of publication of the proposed SNUR, must stop that 
activity before the effective date of the final rule. Persons who 
ceased those activities will have to first comply with all applicable 
SNUR notification requirements and wait until the notice review period, 
including any extensions, expires, before engaging in any activities 
designated as significant new uses. If a person were to meet the 
conditions of advance compliance under 40 CFR [emsp14]721.45(h), the 
person would be considered to have met the requirements of the final 
SNUR for those activities.

[[Page 12086]]

VI. 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.
    Recommended testing that would address the criteria of concern of 
Sec.  721.170 can be found in Unit IV. of the proposed rule. 
Descriptions of tests are provided only for informational purposes. EPA 
strongly encourages persons, before performing any testing, to consult 
with the Agency pertaining to protocol selection.
    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.

VII. SNUN Submissions

    According to Sec.  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.

VIII. Economic Analysis

    EPA has evaluated the potential costs of establishing SNUN 
requirements for potential manufacturers and processors of the chemical 
substance during the development of the direct final rule. EPA's 
complete economic analysis is available in the docket under docket ID 
number EPA-HQ-OPPT-2011-0941.

IX. Statutory and Executive Order Reviews

A. Executive Order 12866

    This final rule establishes a SNUR for a chemical substance that 
was the subject of a PMN. 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 is amending the table in 40 CFR part 9 to list the OMB 
approval number for the information collection requirements contained 
in this 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 does 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 a SNUR does 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 
final rule.
    This final rule is within the scope of the February 18, 2012 
certification. Based on the Economic Analysis discussed in Unit VIII. 
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 will be impacted by this final rule. 
As such, EPA has determined that this action does 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.).

[[Page 12087]]

E. Executive Order 13132

    This action will 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 action does not have Tribal implications because it is not 
expected to have substantial direct effects on Indian Tribes. This 
final rule does not significantly nor uniquely affect the communities 
of Indian Tribal governments, nor does 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 final 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).

X. Congressional Review Act (CRA)

    Pursuant to the Congressional Review Act (5 U.S.C. 801 et seq.), 
EPA will submit a report containing this final 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 final rule in the Federal Register. This action is not a ``major 
rule'' as defined by 5 U.S.C. 804(2).
