SummaryEPA is issuing a significant new use rule (SNUR) under section 5(a)(2) of the Toxic Substances Control Act (TSCA) for the chemical substance identified as 1-Propene, 2,3,3,3-tetrafluoro- (CAS No. 754-12-1) which was the subject of premanufacture notice (PMN) P-07-601. This action requires persons who intend to manufacture, import, or process the chemical substance for a use that is designated as a significant new use by this final rule to notify EPA at least 90 days before commencing that activity. EPA believes that this action is necessary because the chemical substance may be hazardous to human health. 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.
DatesThis final rule is effective November 26, 2010.

Does this action apply to me?You may be potentially affected by this action if you manufacture, import, process, or use the chemical substance contained in this final rule: 1-Propene, 2,3,3,3-tetrafluoro- (PMN P-07-601; CAS No. 754-12-1). Potentially affected entities may include, but are not limited to:
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. For importers of the chemical substance subject to this SNUR those requirements include the SNUR. 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 the chemical substance that is the subject of this final rule on or after November 26, 2010 are subject to the export notification provisions of TSCA section 12(b) (15 U.S.C. 2611(b)) (see § 721.20) and must comply with the export notification requirements in 40 CFR part 707, subpart D.II. BackgroundA. What action is the agency taking?EPA is finalizing a SNUR under TSCA section 5(a)(2) for the chemical substance identified as 1-Propene, 2,3,3,3-tetrafluoro- (PMN P-07-601; CAS No. 754-12-1; aka HFO-1234yf). This action requires persons who intend to manufacture, import, 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.
1. Clarifies the significant new use provisions by organizing them under the following paragraphs of § 721.80: Section 721.80(j) (use other than as a refrigerant in motor vehicle air conditioning systems in new passenger cars and vehicles).
Section 721.80(o) (distribution in commerce of products intended for use by a consumer for the purpose of servicing, maintenance, and disposal involving the PMN substance).2. Removes the following significant new use provisions: All servicing, maintenance, and disposal involving the PMN substance will be done only by CAA section 609 certified technicians using CAA section 609 certified refrigerant handling equipment.
Uses in which the chemical substance will be sold or distributed in other than 20-pound (net weight) containers or larger (this significant new use is now encompassed by § 721.80(o)).Furthermore, EPA has provided in the docket to this rule additional human health information to supplement EPA's findings under § 721.170(d)(3)(i) and EPA's findings in the proposed rule. See Unit IV. of the proposed rule in the Federal Register of April 2, 2010 (75 FR 16706) for a discussion of EPA's findings.B. What is the agency's authority for taking this action?Section 5(a)(2) of TSCA (15 U.S.C. 2604(a)(2)) authorizes EPA to determine that a use of a chemical substance is a “significant new use.” EPA must make this determination by rule after considering all relevant factors, including those listed in TSCA section 5(a)(2). Once EPA determines that a use of a chemical substance is a significant new use, TSCA section 5(a)(1)(B) requires persons to submit a significant new use notice (SNUN) to EPA at least 90 days before they manufacture, import, or process the chemical substance for that use. Persons who must report are described in § 721.5.C. Applicability of General ProvisionsGeneral 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 § 721.1(c), persons subject to this SNUR must comply with the same notice 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.
Chemical importers are subject to the TSCA section 13 (15 U.S.C. 2612) import certification requirements promulgated in Customs and Border Patrol regulations 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. For importers of the chemical substance subject to this final SNUR those requirements include the SNUR. 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 the chemical substance identified in this final SNUR are subject to the export notification provisions of TSCA section 12(b) (15 U.S.C. 2611 (b)) (see § 721.20) and must comply with the export notification requirements in 40 CFR part 707, subpart D.III. Rationale and Objectives of the RuleA. RationaleDuring the review of the chemical substance PMN P-07-601—as discussed in the proposed rule—based on test data on the PMN substance, EPA identified health concerns for developmental toxicity and lethality to workers and consumers if they were exposed to a significant amount of the PMN substance via inhalation. EPA determined that one or more of the criteria of concern established at § 721.170 were met. EPA did not find that the use scenarios described in the PMN triggered the determination set forth under section 5(e) of TSCA. EPA did, however, determine that certain changes from the use scenario described in the PMN could result in increased exposures, thereby constituting a “significant new use.” EPA has determined that activities proposed as a “significant new use” satisfy the two requirements stipulated in § 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.B. ObjectivesEPA is issuing this final SNUR for a chemical substance that has undergone premanufacture review 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, import, or process a listed chemical substance for the described significant new use before that activity begins.
EPA will 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.Issuance of a SNUR for a chemical substance does not signify that the chemical substance is listed on the TSCA Inventory. Guidance on how to determine if a chemical substance is on the TSCA Inventory is available on the Internet at . IV. Significant New Use DeterminationSection 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.
To determine what would constitute a significant new use for HFO-1234yf, EPA considered relevant information—in the docket and discussed further in Unit V. of this document—about the toxicity of the chemical substance, 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, and the regulations at § 721.170 for issuing a SNUR after receipt of a PMN.V. Response to Comments on Proposed SNUR on 1-Propene, 2,3,3,3-tetrafluoro-EPA received comments from a number of submitters on the proposed rule for the chemical substance identified as 1-Propene, 2,3,3,3-tetrafluoro- (PMN P-07-601; CAS No. 754-12-1; aka HFO-1234yf). These comments, many of which covered similar issues, have been grouped under general headings. Many of the comments stated that EPA's risk assessment for the PMN substance overstates both the potential hazards of the chemical substance and the potential exposures from “do-it-yourself” (DIY) consumer use, and uses a health effects endpoint from a toxicity study that is inappropriate given the duration of exposure that could result from DIY consumer use. These commenters evaluated EPA's risk assessment and conducted their own quantitative risk assessments for single, short-term exposure scenarios, using where possible the same information and approach used in EPA's Risk Assessment for the PMN Substance (Ref. 4). A discussion of the comments received and the Agency's responses follows.A. Risk Assessment: ToxicityCommenters stated that adverse health impacts from use of HFO-1234yf under the conditions specified would not be expected for car occupants, servicing personnel, or DIY consumers. The comments relate to the choice of the point of departure (POD) for the Agency's risk assessment of single-exposure (DIY consumers) use scenarios and to the Agency's use of a Margin of Exposure (MOE), as opposed to Hazard Index (HI), approach to evaluate the chemical substance.
Response: This acute 4-hour exposure study in rats showed some lung effects at approximately 200,000 ppm, the lowest exposure level in the study. Thus, EPA considers 200,000 ppm to be a LOAEL (low observed adverse effect level). If a LOAEL were used in the risk assessment instead of a NOAEL (no observed adverse effect level), EPA would use an uncertainty factor to estimate a NOAEL, which would result in a lower POD than what was used. Instead, EPA used the NOAEL for a subacute 14-day study on the chemical substance as the endpoint, because the LOAEL from the acute 4-hour study is an effect endpoint which is inappropriate for developing safe exposure levels for humans. Some of the animals in the 4-hour acute study had grey, discolored lungs at both exposure levels in the study, and EPA considered this an adverse effect. Therefore, EPA could not determine a NOAEL from the acute 4-hour study. It is Agency policy to use the NOAEL where available, because of greater assurance of a “safe” level. Where only the LOAEL is available, that will be used along with any necessary additional uncertainty factors. For example, if EPA had started with the LOAEL of 200,000 ppm, it would have required an additional MOE of 10 to estimate a NOAEL from a LOAEL, for a total MOE of 300 instead of 30. This would have resulted in a more conservative risk assessment than using the NOAEL from the 14-day subacute study.
Perhaps most important to EPA's position on this final SNUR is that EPA has uncertainties about using available single-exposure studies on HFO-1234yf to determine the MOEs for different exposure scenarios. As a result of concerns with these studies, EPA calculated single exposure MOEs from the NOAEL in the 2-week inhalation toxicity study of the PMN chemical in rats. There are some additional uncertainties in the single exposure (acute) assessments because of the observation of lethality in rabbit dams after multiple exposures in a developmental study to the PMN substance. For these reasons, as mentioned in Unit IV. of the proposed SNUR, EPA recommends a rabbit acute inhalation toxicity study to address the question of whether pregnant rabbits would die from a single exposure. Rabbits should be exposed for one hour, using the Organisation for Economic Co-operation and Development (OECD) 403 test guideline. Pregnant rabbits should be exposed on gestational day 12 (this is within the time-frame that pregnant rabbits started dieing in the developmental study).B. Risk Assessment: Exposure Comment: Commenter stated that EPA's assessment, using the Gradient Report (Ref. 6), overstates the potential exposures from consumer DIY use of HFO-1234yf to refill MVAC systems. The commenter asserted that EPA's methodology to estimate the exposure levels associated with the DIY use greatly exaggerates the exposure that could be experienced in actual use conditions. The specific exposure parameters that the commenters questioned were assumptions regarding: Garage volume.
The amount of refrigerant used during recharge operations.During the comment period for the proposed SNUR, the PMN submitter conducted a simulated vehicle service leak testing, using HFC-134a as a surrogate, indicating that exposures from use of a 12-oz can during consumer DIY use are below the Agency's level of concern for HFO-1234yf (Ref. 7).
Response: After reviewing the submitted consumer DIY use exposure study, EPA responded with a list of clarifying questions (Ref. 5), to which the PMN submitter subsequently responded (Ref. 8). Although the PMN submitter's responses were helpful, EPA still has concerns about potential exposures to consumers during DIY use and the inherent toxicity of HFO-1234yf. Therefore, the Agency has decided to retain requirements in the final rule for notification to the Agency prior to distribution in commerce of products intended for use by DIY consumers, while waiting for data from the acute inhalation toxicity study in rabbits described in Unit V.A. With regards to exposure, the peak concentration values from the submitted study are as high as 3% by volume, equivalent to 30,000 ppm. These peaks appeared to occur in the first one or two minutes of each emission. Accordingly, EPA would need exposure data presented and averaged out over shorter Time Weighted Averages (TWAs) than the 30 minutes currently in the study, because it would appear that a number of these early exposure peaks could result in TWA values that would result in MOEs less than the acceptable Agency level of 30 (see Unit V.A.). This is important because the data on HFO-1234yf are insufficient to differentiate whether the toxicity is due to blood level alone from an acute exposure, is due to accumulated exposure over time (area under the curve), or is due to some combination of both. Since blood equilibrium levels are reached within minutes, a high level of exposure in a short duration could result in blood levels exceeding a threshold if the mode of action is due to blood levels. Additional TWAs of 3, 5, and 10 minutes are recommended.
Information on such techniques or equipment to minimize potential exposures to DIY consumers should accompany any SNUN submitted in response to this final SNUR that requests use of HFO-1234yf in DIY consumer products. Other information submitted with such a SNUN should include data that quantifies exposures for durations shorter than the 30-minute TWA presented in the exposure study submitted by the PMN submitter, in particular, TWAs for 3 minutes, 5 minutes, and 10 minutes, in addition to 30 minutes.C. CAA Section 609 Certification Comment: One commenter stated that the training and equipment requirements currently in CAA section 609 relative to other refrigerants would not be necessary for environmentally safe usage of HFO-1234yf during initial charging in an automobile assembly plant. The commenter stated that a CAA section 609 certification is not currently required for automobile assembly plants workers or equipment; manufacturers perform their own training programs; and Occupational Safety and Health Administration (OSHA) requirements for handling flammable substances already fully address the flammability-related HFO-1234yf worker safety issues in automobile assembly facilities.
The following scenarios are not covered under CAA section 609: Initial charge of an MVAC by OEMs.
Servicing on gratitude (service done for free). For example, a DIY individual if not being paid with cash, credits, goods, or service would not be covered under CAA section 609 requirements.Furthermore, intentionally venting any refrigerant is prohibited under section 608 of the CAA and under 40 CFR 82.154 (a)(1).
Therefore, EPA agrees with the commenter and has modified the relevant language in the regulatory text of the proposed rule to remove specific references to the CAA section 609 certification.D. Use of HFO-1234yf as a Delivery Agent Comment: One commenter expressed concern that HFC-134a refrigerant has been used to deliver chemicals into MVAC systems for the advertised purpose of increasing system-cooling performance and/or injecting oil, trace dyes, sealants to stop refrigerant system leakage, etc. The commenter requests that EPA not allow use of HFO-1234yf as transfer/delivery agent for such purposes. Another commenter requested that HFO-1234yf not be allowed for this use due to health concerns.
Response: Prior to marketing HFO-1234yf as a delivery agent, a person would need to submit notices to EPA under both the CAA SNAP program and under TSCA. If a person plans to market HFO-1234yf as a “delivery agent” in cans, rather than as a refrigerant for MVAC, then they must submit a SNAP information notice to EPA for use of HFO-1234yf as an aerosol propellant. Under the SNAP program, the person would be allowed to market HFO-1234yf as an aerosol propellant 90 days after submission of a complete notice. Similarly, under the SNUR, that person would also need to submit a SNUN 90 days before engaging in a use other than as a refrigerant in MVAC, such as a delivery agent. In many cases, EPA responds to a SNUN by amending the SNUR to allow companies other than the SNUN submitter (such as the submitter's processor customers) to engage in the newly approved use(s).VI. Applicability of Rule to Uses Occurring Before Effective Date of the Final RuleAs discussed in the Federal Register of April 24, 1990 (55 FR 17376), 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 the proposed SNUR rather than as of the effective date of the final rule. If uses begun after publication were considered ongoing, rather than new, it would be difficult for EPA to establish SNUR notice requirements because a person could defeat the SNUR by initiating the proposed significant new use before the rule became effective, and then argue that the use was ongoing as of the effective date of the final rule.
Any person who began commercial manufacture, import, or processing of 1-Propene, 2,3,3,3-tetrafluoro- (PMN P-07-601; CAS No. 754-12-1; aka HFO-1234yf) 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 this final rule. Persons who ceased those activities will have to meet all SNUR notice requirements and wait until the end of the notification review period, including all extensions, before engaging in any activities designated as significant new uses. If, however, persons who began manufacture, import, or processing of the chemical substance between the date of publication of the proposed SNUR and the effective date of this final SNUR meet the conditions of advance compliance as codified at § 721.45(h), those persons would be considered to have met the final SNUR requirements for those activities.VII. Test Data and Other InformationEPA recognizes that TSCA section 5 does not require the development of any particular test data before submission of a SNUN. There are two exceptions:
In the absence of a section 4 test rule or a 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 this case, EPA recommends a rabbit acute inhalation toxicity study to address human health concerns. EPA strongly encourages persons, before performing any testing, to consult with the Agency pertaining to protocol selection. The OECD test guidelines are available from the OECD Bookshop at or SourceOECD at . The recommended tests may not be the only means of addressing the potential risks of the chemical substance. However, SNUNs submitted without any test data may increase the likelihood that EPA will respond by taking 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.
Information on risks posed by the chemical substance compared to risks posed by potential substitutes.VIII. SNUN SubmissionsAs stated in Unit II.C. of this document, according to § 721.1(c), persons submitting a SNUN must comply with the same notice 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 to EPA on EPA Form No. 7710-25 in accordance with the procedures set forth in § 721.25 and § 720.40. This form is available from the Environmental Assistance Division (7408M), 1200 Pennsylvania Ave., NW., Washington, DC 20460-0001. Forms and information are also available on-line at . IX. Economic AnalysisEPA evaluated the potential costs of establishing SNUN requirements for potential manufacturers, importers, and processors of the chemical substance 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.X.

Executive Order 12866This 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 ActAccording 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. 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.
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 ActPursuant to section 605(b) of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et seq.), the Agency hereby certifies that promulgation of this SNUR will not have a significant adverse economic impact on a substantial number of small entities. The rationale supporting this conclusion is discussed in this unit. The requirement to submit a SNUN applies to any person (including small or large entities) who intends to engage in any activity described in the final rule as a “significant new use.” Because these uses are “new,” based on all information currently available to EPA, it appears that no small or large entities presently engage in such activities. A SNUR requires that any person who intends to engage in such activity in the future must first notify EPA by submitting a SNUN. Although some small entities may decide to pursue a significant new use in the future, EPA cannot presently determine how many, if any, there may be. However, EPA's experience to date is that, in response to the promulgation of over 1,400 SNURs, the Agency receives on average only 5 notices per year. Of those SNUNs submitted from 2006-2008, only one appears to be from a small entity. In addition, the estimated reporting cost for submission of a SNUN (see Unit IX.) is minimal regardless of the size of the firm. Therefore, EPA believes that the potential economic impacts of complying with these SNURs are not expected to be significant or adversely impact a substantial number of small entities. In a SNUR that published in the Federal Register of June 2, 1997 (62 FR 29684) (FRL-5597-1), the Agency presented its general determination that final SNURs are not expected to have a significant economic impact on a substantial number of small entities, which was provided to the Chief Counsel for Advocacy of the Small Business Administration.D. Unfunded Mandates Reform ActBased 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 rule does not impose any enforceable duty, contain any unfunded mandate, or otherwise have any affect on small governments subject to the requirements of sections 202, 203, 204, or 205 of the Unfunded Mandates Reform Act of 1995 (UMRA) (Pub. L. 104-4).E. 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. This final rule does not have Tribal implications because it is not expected to have substantial direct effects on Indian Tribes. This does not significantly or 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. 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.

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