Proposed Modification of Significant New Uses of 1-Propene, 
2,3,3,3-tetrafluoro-

AGENCY: Environmental Protection Agency (EPA).

[[Page 32618]]


ACTION: Proposed rule.

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

SUMMARY: Under section 5(a)(2) of the Toxic Substances Control Act 
(TSCA), EPA is proposing to amend the significant new use rule (SNUR) 
for the chemical substance identified as 1-Propene, 2,3,3,3-
tetrafluoro-, which was the subject of premanufacture notice (PMN) P-
07-601. This action would amend the SNUR to allow the manufacture and 
processing for certain uses without requiring a significant new use 
notice (SNUN). EPA is proposing this amendment based on review of newly 
submitted exposure and toxicity data.

II. Background

A. What action is the Agency taking?

    In the Federal Register of October 27, 2010 (75 FR 65987) (FRL-
8846-8), EPA published a final SNUR (codified at Sec.  721.10182) for 
the chemical substance identified as 1-Propene, 2,3,3,3-tetrafluoro-, 
(PMN P-07-601; CAS No. 754-12-1; which is also identified by the trade 
name HFO-1234yf), in accordance with the procedures at Sec.  721.170. A 
SNUR requires persons who intend to manufacture, import, or process the 
chemical substance for an activity designated as a significant new use 
to notify EPA at least 90 days before commencing that activity.
    EPA is proposing to amend the scope of the SNUR as detailed in this 
unit. In addition, EPA is proposing to clarify the language in the 
regulatory text to more clearly communicate that the manufacture and 
processing for use as a refrigerant in motor vehicle air conditioning 
systems in new passenger cars and vehicles as reported in the original 
PMN is not subject to the notification requirement. The docket includes 
information considered by the Agency in developing the final rule and 
the new information considered when proposing the modification to this 
rule.
PMN Number P-07-601
    Chemical name: 1-Propene, 2,3,3,3-tetrafluoro-.
    CAS number: 754-12-1.
    Federal Register publication date and reference: October 27, 2010 
(75 FR 65987).
    Basis for modification of the SNUR: In the final SNUR, EPA 
explained that it sought additional information to review use by 
consumers attempting to recharge air conditioning systems in vehicles 
originally charged with the refrigerant. Specifically, EPA sought an 
acute rabbit inhalation toxicity study to better characterize health 
effects from a single exposure and sought additional information on 
techniques or equipment to minimize exposure to consumers and data that 
quantifies exposures for durations shorter than the 30-minute time-
weighted average (TWA) presented in the exposure study conducted by the 
PMN submitter. In response, the PMN submitter conducted an acute 
inhalation toxicity study with rabbits on the PMN substance. The 
submitted results demonstrated no toxicity in the one-hour exposure of 
rabbits to 0, 50,000, and 100,000 parts per million (ppm) of the PMN 
substance. The human equivalent concentration of the 100,000 ppm 
exposure in rabbits is 190,000 ppm and was utilized for a risk 
assessment. In addition, potential after-market manufacturers and the 
PMN submitter also provided additional information on the previously 
submitted exposure study that was conducted quantifying the exposures 
for durations shorter than 30 minutes and data on exposures from use of 
certain specified fittings. The test conditions demonstrated a highest 
30-minute TWA exposure of 1,789 ppm. Based on the newly submitted data, 
EPA calculated the ratio of the level of exposure in rabbits that did 
not cause any effects with the highest measured TWA exposure. The 
calculated ratio is 106, which EPA considers protective of human 
health. The detailed risk assessment is contained in the public docket. 
Based on this new assessment, EPA proposes to find that use of the PMN 
substance by consumers to recharge air conditioning systems in vehicles 
originally charged with the refrigerant by the motor vehicle original 
equipment manufacturer (OEM) no longer meets the concern criteria at 
Sec.  721.170(b). Based on this proposed finding, EPA is proposing to 
modify the SNUR by eliminating the requirement to submit a notice prior 
to the manufacture and processing for the specified consumer use of the 
PMN substance.
    In addition, EPA is proposing to clarify the language in the 
regulatory text to more clearly communicate that manufacture and 
processing for use as a refrigerant in motor vehicle air conditioning 
systems in new passenger cars and vehicles as reported in the original 
PMN is not a significant new use. The current regulatory text 
identifies the significant new use by reference to 40 CFR 721.80(j), 
which refers to any ``use other than'' a use described in the 
premanufacture notice and then uses a parenthetical to more 
specifically identify the significant new use, beginning with ``use 
other than.'' However, using the language ``use other than'' when 
referring to a regulatory provision which begins with ``use other 
than'' can be confusing. As a result, EPA is proposing to clarify the 
regulatory text by simply identifying the significant new use as use 
other than as a refrigerant in motor vehicle air conditioning systems 
in new passenger cars and vehicles (i.e., as defined in 40 CFR 82.32 
(c) and (d). The docket established for this proposed amendment to the 
SNUR is available under docket ID number EPA-HQ-OPPT-2008-0918.
    CFR citation: 40 CFR 721.10182.

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 TSCA section 5(a)(2) factors, listed in 
Unit III. of this document. 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 requires persons to submit a significant new use 
notice (SNUN) to EPA at least 90 days before they manufacture 
(including import) or process the chemical substance for that use. 
Persons who must report are described in Sec.  [emsp14]721.5.
    EPA may respond to SNUNs by, among other things, issuing or 
modifying a TSCA section 5(e) consent order and/or amending the SNUR 
promulgated under TSCA section 5(a)(2). Amendment of the SNUR will 
often be necessary to allow persons other than the SNUN submitter to 
engage in the newly authorized use(s), because even after a person 
submits a SNUN and the review period expires, other persons still must 
submit a SNUN before engaging in the significant new use.

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 to 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.

[[Page 32620]]

    In addition to these factors enumerated in TSCA section 5(a)(2), 
the statute authorizes EPA to consider any other relevant factors.
    To determine that consumer use in the recharge of motor vehicle air 
conditioning systems originally charged with the PMN substance by the 
motor vehicle OEM is not a significant new use of the chemical 
substance identified as 1-Propene, 2,3,3,3-tetrafluoro-(PMN P-07-601), 
EPA considered relevant information about the toxicity of the chemical 
substance, likely human exposures and environmental releases associated 
with this chemical use, taking into consideration the four bulleted 
TSCA section 5(a)(2) factors listed in this unit.

IV. Rationale for the Proposed Rule

    During review of PMN P-07-601, the chemical substance identified as 
1-Propene, 2,3,3,3-tetrafluoro-, EPA determined that one or more of the 
criteria of concern established at Sec.  721.170 were met and 
regulation under section 5(a)(2) of TSCA was warranted. The basis for 
such findings is outlined in Unit II. of this document and in the 
Federal Register document of June 26, 1990 (55 FR 26102). Based on 
these findings, a SNUR was promulgated pursuant to Sec.  
[emsp14]721.170.
    After the review of new test data and information subsequent to 
issuance of the SNUR (see Unit II.), and consideration of the factors 
included in TSCA section 5(a)(2) (see Unit III.), EPA proposes to find 
that the concern criteria in Sec.  721.170(b), are no longer met for 
the consumer use in the recharge of motor vehicle air conditioning 
systems originally charged with the PMN substance by the motor vehicle 
OEM.

V. Economic Analysis

    EPA evaluated the potential costs of establishing SNUN requirements 
for potential manufacturers, importers, and processors of the chemical 
substances during the development of the direct final rule. The 
Agency's complete Economic Analysis is available in the docket under 
docket ID number EPA-HQ-OPPT-2008-0918. This proposal will not add to 
the costs identified in that analysis as it would, if finalized, 
relieve an existing notification requirement for certain manufacturers 
and processors.

VI. Statutory and Executive Order Reviews

A. Executive Order 12866

    This proposed rule would modify a SNUR for a chemical substance 
that is 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

    According to the Paperwork Reduction Act (PRA), 44 U.S.C. 3501 et 
seq., an Agency may not conduct or sponsor, and a person is not 
required to respond to a collection of information that requires OMB 
approval under the PRA, unless it has been approved by OMB and displays 
a currently valid OMB control number. The OMB control numbers for EPA's 
regulations in title 40 of the CFR, after appearing in the Federal 
Register, are listed in 40 CFR part 9, and included on the related 
collection instrument or form, if applicable. 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 proposed rule would, if finalized, relieve an existing 
notification requirement for certain manufacturers and processors. 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 under the existing SNUR, 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

    On February 18, 2012, EPA certified pursuant to section 605(b) of 
the Regulatory Flexibility Act (RFA) (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 SNUN 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 
rule.
    This rule is within the scope of the February 18, 2012 
certification. Based on the Economic Analysis discussed in Unit V. 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 amendment.
     Submission of the SNUN would not cost any small entity 
significantly more than $8,300. Therefore, the promulgation of the SNUR 
amendment would not have a significant economic impact on a substantial 
number of small entities.

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 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 
sections 202, 203, 204, or 205 of the Unfunded Mandates Reform Act of 
1995 (UMRA) (Pub. L. 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 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

[[Page 32621]]

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 proposed rule is not subject to Executive Order 13211, 
entitled Actions Concerning Regulations That Significantly Affect 
Energy Supply, Distribution, or Use (66 FR 28355, May 22, 2001), 
because this action is not expected to affect energy supply, 
distribution, or use and because this action is not a significant 
regulatory action under Executive Order 12866.

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 FR7629, February 16, 1994).
