Under the Toxic Substances Control Act (TSCA), EPA is amending a significant new use rule (SNUR) for perfluoroalkyl sulfonate (PFAS) chemical substances to add PFAS chemical substances that have completed the TSCA new chemical review process, but have not yet commenced production or import and is designating (for all listed PFAS chemical substances) processing as a significant new use. EPA is also finalizing a SNUR for long-chain perfluoroalkyl carboxylate (LCPFAC) chemical substances that designates manufacturing (including importing) and processing for use as part of carpets or for treating carpet (e.g., for use in the carpet aftercare market) as a significant new use, except for use of two chemical substances as a surfactant in carpet cleaning products. For this SNUR, EPA is also making an exemption inapplicable to persons who import or process the LCPAC chemical substances as part of an article. Persons subject to these SNURs will be required to notify EPA at least 90 days before commencing any significant new use. The required notifications will provide EPA with the opportunity to evaluate the intended use and, if necessary, to prohibit or limit that activity before it occurs.

You may be potentially affected by this action if you manufacture (including import) or process any of the chemical substances listed in Table 4 of the regulatory text in this document or that meet the LCPFAC chemical category definition as described in this rule.
Manufacturers (including importers) of one or more of subject chemical substances (North American Industrial Classification System (NAICS) codes 325 and 324110); e.g., chemical manufacturing and petroleum refineries.
Carpet and upholstery cleaning services (NAICS code 561740).
This listing is not intended to be exhaustive, but rather provides a guide for readers regarding entities likely to be affected by this action. Other types of entities not listed in this unit could also be affected. The NAICS codes have been provided to assist you and others in determining whether this action might apply to certain entities. To determine whether you or your business may be affected by this action, you should carefully examine the applicability provisions in 40 CFR 721.5, 40 CFR 721.9582, and 40 CFR 721.10536, which is in the regulatory text of this document. If you have any questions regarding the applicability of this action to a particular entity, consult the technical person listed under FOR FURTHER INFORMATION CONTACT.
This action may also affect certain entities through pre-existing import certification and export notification rules under TSCA. Persons who import any chemical substance governed by a final SNUR are subject to the TSCA section 13 (15 U.S.C. 2612) import certification requirements and the corresponding regulations at 19 CFR 12.118 through 12.127; see also 19 CFR 127.28. Those persons must certify that the shipment of the chemical substance complies with all applicable rules and orders under TSCA, including any SNUR requirements. The EPA policy in support of import certification appears at 40 CFR part 707, subpart B. In addition, any persons who export or intend to export a chemical substance that is the subject of this rule are subject to the export notification provisions of TSCA section 12(b) (15 U.S.C. 2611(b)), (see 40 CFR 721.20), and must comply with the export notification requirements in 40 CFR part 707, subpart D.
In the Federal Register of August 15, 2012 (77 FR 48924) (FRL-9358-7), EPA proposed to amend a SNUR at 40 CFR 721.9582 for PFAS chemical substances to add PFAS chemical substances that have completed the TSCA new chemical review process, but have not yet commenced production or import, and to designate (for all listed PFAS chemical substances) processing as a significant new use. In addition, the Agency also proposed a new SNUR for LCPFAC chemical substances that designates manufacturing (including importing) and processing for use as part of carpets or for treating carpet (e.g., for use in the carpet aftercare market) as a significant new use. On December 30, 2009, EPA issued the “Long-Chain Perfluorinated Chemicals (PFCs) Action Plan” (Ref. 1). Today's action is consistent with the purpose of that action plan.
The term PFAS refers to a general category of perfluorinated sulfonate chemical substances of any chain Start Printed Page 62445length. The PFAS chemical substances for which EPA is modifying an existing SNUR are currently listed in 40 CFR 721.9582 in paragraph (a)(1). The PFAS chemical substances that EPA is adding to an existing SNUR are being inserted into this list. All of these chemical substances are collectively referred to in this rule as perfluoroalkyl sulfonates, or PFAS chemical substances.
a. CF3 (CF2)n-COO− M where M = H+ or any other group where a formal dissociation can be made;
b. CF3 (CF2)n-CH=CH2;
c. CF3 (CF2)n-C(=O)-X where X is any chemical moiety;
d. CF3 (CF2)m-CH2-X where X is any chemical moiety, and
e. CF3 (CF2)m-Y-X where Y = non-S, non-N heteroatom and where X is any chemical moiety.
It is important to note that any LCPFAC chemical substance identified by paragraphs (b)(1)(i) through (b)(1)(v) of this final rule that is intentionally used during fluoropolymer formulation, such as an emulsion stabilizer in aqueous dispersions, is subject to reporting for the significant new uses described in 40 CFR 721.10536(b)(2). For example, ammonium perfluorooctanoate (APFO)—when used as an aqueous dispersion agent in fluoropolymer production—is subject to this SNUR if the final fluoropolymer product is used as part of carpets or to treat carpets.
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 SNUN to EPA at least 90 days before they manufacture (including import) or process the chemical substance for that use (15 U.S.C. 2604(a)(1)(B)). As described in Unit II.C., the general SNUR provisions are found at 40 CFR part 721, subpart A.
General provisions for SNURs appear under 40 CFR part 721, subpart A. These provisions describe persons subject to the rule, recordkeeping requirements, exemptions to reporting requirements, and applicability of the rule to uses occurring before the effective date of the final rule. However, EPA is making the exemption at 40 CFR 721.45(f) inapplicable to persons who import LCPFAC chemical substances as part of carpets under this SNUR. As a result, persons subject to the provisions of this rule would not be exempt from significant new use reporting if they import LCPFAC chemical substances as part of carpets. However, the articles exemption will remain in effect for persons who process chemical substances as part of an article because existing stocks of carpets may still contain LCPFAC substances.
Provisions relating to user fees appear at 40 CFR part 700. According to 40 CFR 721.1(c), persons subject to SNURs must comply with the same notice requirements and EPA regulatory procedures as submitters of premanufacture notices (PMNs) under TSCA section 5(a)(1)(A). In particular, these requirements include the information submissions 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 on 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.
As discussed in Units III. and IV. of the proposed rule (77 FR 48924; August 15, 2012), PFAS and LCPFAC chemical substances are found world-wide in the environment, wildlife, and humans. They are bioaccumulative in wildlife and humans, and are persistent in the environment. They are toxic to laboratory animals, producing reproductive, developmental, and systemic effects in laboratory tests. The exact sources and pathways by which these chemicals move into and through the environment and allow humans and wildlife to become exposed are not fully understood, but are likely to include releases from manufacturing of the chemicals, processing of these chemicals into products like carpets and textiles, and aging and wear of products containing them.
Since the manufacture (including import) and processing of PFAS and LCPFAC chemical substances for these uses have been discontinued in the United States, EPA expects their presence in humans and the environment to decline over time as has been observed in the past when production and use of other persistent chemicals has ceased. EPA is concerned that the manufacturing (including import) or processing of these chemical substances, as well as importing these chemicals as part of articles, for the new uses identified in this rule could be reinitiated in the future. If reinitiated, EPA believes that such use would increase the magnitude and duration of human and environmental exposure to Start Printed Page 62446these chemical substances, constituting a significant new use.
With this action, the Agency is designating as significant new uses of LCPFAC chemical substances use as part of carpet or to treat carpet. The Agency believes the 2010/2015 PFOA Stewardship Program, in which companies committed to work toward eliminating facility emissions and product content of PFOA—a LCPFAC chemical substance—by 2015, will eliminate many other ongoing uses of LCPFAC chemical substances. As those uses are phased out in the United States, EPA anticipates taking additional regulatory actions to prevent resumption of the uses without prior notice to EPA.
Based on the considerations in Unit III.A. of this rule, EPA will achieve the following objectives with regard to the significant new use(s) that are designated in this rule:
3. EPA will be able to regulate prospective manufacturers (including importers) or processors of PFAS or LCPFAC chemical substances before the described significant new use of the chemical substance occurs, provided that regulation is warranted pursuant to TSCA sections 5(e), 5(f), 6 or 7.
Exposure to LCPFAC chemical substances may occur both during the carpet manufacture process and during the lifetime of the finished carpet via inhalation and ingestion of dust generated from the abrasion of carpets. This is of particular concern for children since they engage in a variety of activities on carpets for longer periods of time and have a greater degree of hand-to-mouth activity in their earliest years. This will change both the magnitude of exposure and the duration of exposure. Except for one ongoing use specified in 40 CFR 721.10536(b)(3), the Agency believes the manufacture (including import) and processing of LCPFAC chemical substances as part of carpet or to treat carpet has been discontinued. EPA also believes LCPFAC chemicals substances are no longer imported as part of carpet. If reinitiated, EPA believes these uses of LCPFAC chemical substances would significantly increase the magnitude and duration of exposure to humans and the Start Printed Page 62447environment relative to what currently exists. Based on these considerations of the statutory factors discussed in this unit, EPA has determined that the manufacture (including import) or processing of any of the LCPFAC chemical substances subject to this rule for use as part of carpet or to treat carpets, except ongoing uses specified in 40 CFR 721.10536(b)(3), is a significant new use. EPA has further determined that importing any of the LCPFAC chemical substances subject to this rule as part of carpet constitutes a significant new use and warrants making inapplicable the article exemption at 40 CFR 721.45(f).
As 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 rule rather than as of the effective date of the final rule. If uses begun after publication of the proposed rule were considered ongoing rather than new, it would be difficult for EPA to establish SNUR notice requirements, because a person could defeat the SNUR by initiating the proposed significant new use before the rule became final, and then argue that the use was ongoing as of the effective date of the final rule. Thus, persons who may have begun commercial manufacture (including import) or processing of the chemical substance(s) subject to this rule for a significant new use after the proposal was published on August 15, 2012 (77 FR 48924), must cease such activity before the effective date of this final rule. To resume their activities, these persons will have to comply with all applicable SNUR notice requirements and wait until the notice review period, including all extensions, expires. Uses arising after the publication of the proposed rule are distinguished from uses that exist at publication of the proposed rule. The former would be new uses, the latter ongoing uses. To the extent that additional ongoing uses were found in the course of rulemaking, EPA has excluded these uses from the final SNUR. EPA promulgated provisions to allow persons to comply with this SNUR before the effective date. If a person were to meet the conditions of advance compliance under 40 CFR 721.45(h), that person would be considered to have met the requirements of the final SNUR for those activities.
EPA recognizes that TSCA section 5 does not usually require developing any particular test data before submission of a SNUN. There are two exceptions: (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)); and (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 (15 U.S.C. 2604(d); 40 CFR 721.25; and 40 CFR 720.50). However, as a general matter, EPA recommends that SNUN submitters include data that would permit a reasoned evaluation of risks posed by the chemical substance during its manufacture (including import), processing, use, distribution in commerce, or disposal. EPA encourages persons to consult with the Agency before submitting a SNUN. As part of this optional pre-notice consultation, EPA would discuss specific data it believes may be useful in evaluating a significant new use. SNUNs submitted for significant new uses without any test data may increase the likelihood that EPA will take action under TSCA section 5(e) to prohibit or limit activities associated with this chemical.
EPA recommends that submitters consult with the Agency prior to submitting a SNUN to discuss what data may be useful in evaluating a significant new use. Discussions with the Agency prior to submission can afford ample time to conduct any tests that might be helpful in evaluating risks posed by the substance. According to 40 CFR 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 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 721.25 and 40 CFR 720.40. E-PMN software is available electronically at http://www.epa.gov/​opptintr/​newchems.
This action finalizes the SNUR proposed in the Federal Register on August 15, 2012 (77 FR 48924). This final rule requires persons who intend to manufacture (including import) or process one or more of the chemical substances listed in Table 4 of the regulatory text for the uses identified in 40 CFR 721.9582(a)(2) to submit a SNUN at least 90 days before commencing manufacture (including import) or processing. This rule also requires persons who intend to manufacture (including import) or process one or more LCPFAC chemical substances, as defined in 40 CFR 721.10536(b)(1), for use as part of carpets or for treating carpets (except for one specifically identified ongoing use of two LCPFAC chemical substances as a surfactant in aftermarket carpet cleaning products) to submit a SNUN at least 90 days before commencing manufacture (including import) or processing.
1. Comment summary. In defining the chemicals subject to this SNUR in the proposed rule, no upper limit was given for carbon chain length. Submitters suggested an upper limit of 20 carbons, which would exclude from the LCPFAC Start Printed Page 62448category definition polymers weighing greater than 1,000 daltons.
5. Comment summary. A submitter suggested that 40 CFR 721.10536(b)(1)(ii) of the regulatory text should state “CF3 (CF2)m CH=CH2, where m > 6” rather than “CF3 (CF2)n CH=CH2, where n > 5” to be consistent with PFOA precursors identified in the PFOA Stewardship Program.
Response. Fluoropolymers are not subject to this SNUR. In the preamble of the proposed rule, the Agency referred to a `contaminated' chemical as one that does not meet the LCPFAC definition itself, but that contains a LCPFAC chemical substance due to its intentional use during chemical formulation. In such a case, this LCPFAC chemical substance would be subject to this SNUR for the significant new uses described in 40 CFR 721.10536(b)(2). For example, APFO used as an emulsifier in the production of fluoropolymers would be subject to this SNUR for the significant new uses described in 40 CFR 721.10536(b)(2).
EPA has evaluated the potential costs of establishing SNUR reporting requirements for potential manufacturers (including importers) and processors of the chemical substance included in this rule (Ref. 2). In the event that a SNUN is submitted, costs are estimated at $8,589 per SNUN submission for large business submitters and $6,189 for small business submitters. These estimates include the cost to prepare and submit the SNUN, and the payment of a user fee. Businesses that submit a SNUN would be subject to either a $2,500 user fee required by 40 CFR 700.45(b)(2)(iii), or, if they are a small business with annual sales of less than $40 million when combined with those of the parent company (if any), a reduced user fee of $100 (40 CFR 700.45(b)(1)). The costs of Start Printed Page 62449submission of SNUNs will not be incurred by any company unless a company decides to pursue a significant new use as defined in this SNUR. EPA's complete economic analysis is available in the public docket for this rule (Ref. 2).
While not required by the SNUR, these parties may incur costs to take additional steps to determine whether the articles they plan to import are covered by this SNUR. This determination may involve gathering information from suppliers along the supply chain, and/or testing samples of the article itself. EPA believes that the LCPFAC chemical substances included in this final rule are no longer being manufactured (including imported) for use as part of carpet or for treating carpet (e.g., for use in the carpet aftercare market) in the United States, except for use of two chemical substances in carpet cleaning solution, and that LCPFAC chemical substances are not being imported as part of carpets. Therefore, EPA believes that these costs would be minimal.
Under TSCA section 12(b) and the implementing regulations at 40 CFR part 707, subpart D, exporters must notify EPA if they export or intend to export a chemical substance or mixture for which, among other things, a rule has been proposed or promulgated under section 5. For persons exporting a substance the subject of a SNUR, a one-time notice must be provided for the first export or intended export to a particular country. The total costs of export notification will vary by chemical, depending on the number of required notifications (i.e., the number of countries to which the chemical is exported). EPA is unable to make any estimate of the likely number of export notifications for the chemical covered in this SNUR.
As indicated under ADDRESSES, a docket has been established for this rule under docket ID number EPA-HQ-OPPT-2012-0268. The following is a listing of the documents cited in this document. The docket includes information considered by EPA in developing this rule, including the documents listed in this unit, which are physically located in the docket. In addition, interested parties should consult documents that are referenced in the documents that EPA has placed in the docket, regardless of whether these referenced documents are physically located in the docket. For assistance in locating documents that are referenced in documents that EPA has placed in the docket, but that are not physically located in the docket, please consult the technical person listed under FOR FURTHER INFORMATION CONTACT.

2. USEPA. “Economic Analysis of the Significant New Use Rule for Perfluoroalkyl Sulfonates and Long-Chain Perfluoroalkyl Carboxylate Chemical Substances.” Prepared by Timothy Lehman and Abt Associates Inc. May 7, 2013.
Under Executive Order 12866 (58 FR 51735, October 4, 1993), the Office of Management and Budget (OMB) has determined that this SNUR is not a “significant regulatory action,” because it does not meet the criteria in section 3(f) of the executive order. Accordingly, this action was not reviewed by OMB under Executive Orders 12866 and 13563 (76 FR 3821; January 21, 2011).
According to the 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. The information collection requirements related to this action have already been approved by OMB pursuant to the PRA under OMB control number 2070-0038 (EPA ICR No. 1188). This action does not impose any burden requiring additional OMB approval. If an entity were to submit a SNUN to the Agency, the annual burden is estimated to average 92 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.
Pursuant to section 605(b) of the RFA, 5 U.S.C. 601 et seq., the Agency hereby certifies that promulgation of this SNUR would not have a significant economic impact on a substantial number of small entities. The rationale supporting this conclusion is as follows. A SNUR applies to any person (including small or large entities) who intends to engage in any activity described in the rule as a “significant new use.” By definition of the word “new” and based on all information currently available to EPA, it appears that no small or large entities presently engage in such activity. Since this SNUR will require a person who intends to engage in such activity in the future to first notify EPA by submitting a SNUN, no economic impact will occur unless someone files a SNUN to pursue a significant new use in the future or forgoes profits by avoiding or delaying the significant new use. Although some small entities may decide to conduct such activities in the future, EPA cannot presently determine how many, if any, there may be. However, EPA's experience to date is that, in response to the promulgation of SNURs covering over 1,000 chemical substances, the Agency receives only a handful of notices per year. For example, the number of SNUNs was four in Federal fiscal year (FY) 2005, eight in FY 2006, six in FY 2007, eight in FY 2008, and seven in FY 2009. During this 5-year period, three small entities submitted a SNUN. Therefore, EPA believes that the potential economic impact of complying with this SNUR is not expected to be significant or adversely impact a substantial number of small entities. In a SNUR that published as a final rule on August 8, 1997 (62 FR 42690) (FRL-5735-4), the Agency presented its general determination that proposed and final SNURs are not expected to have a significant economic impact on a substantial number of small entities, which was provided to the Chief Counsel for Advocacy of the Small Business Administration.Start Printed Page 62450
Based on EPA's experience with proposing and finalizing SNURs, State, local, and Tribal governments have not been impacted by these rulemakings, and EPA does not have any reason to believe that any State, local, or Tribal government would be impacted by this rulemaking. As such, EPA has determined that this regulatory action would not impose any enforceable duty, contain any unfunded mandate, or otherwise have any effect on small governments subject to the requirements of sections 202, 203, 204, or 205 of UMRA, 2 U.S.C. 1531-1538.
This rule does not have Tribal implications because it is not expected to have substantial direct effects on Indian Tribes. This rule does not significantly or uniquely affect the communities of Indian Tribal governments, nor involve or impose any requirements that affect Indian Tribes. Accordingly, the requirements of Executive Order 13175 (65 FR 67249, November 9, 2000) do not apply to this rule.
This rule is not subject to Executive Order 13211 (66 FR 28355, May 22, 2001), because this action is not expected to affect energy supply, distribution, or use.
Since this action does not involve any technical standards; section 12(d) of the NTTAA, 15 U.S.C. 272 note, does not apply to this action.

(iv) CF3 (CF2)m-CH2-X where X is any chemical moiety; and
(v) CF3 (CF2)m-Y-X where Y = non-S, non-N heteroatom and where X is any chemical moiety.
(1) Revocation of certain notification exemptions. With respect to imports of carpets, the provisions of § 721.45(f) do not apply to this section. A person who imports a chemical substance identified in this section as part of a carpet is not exempt from submitting a significant new use notice. The other provision of § 721.45(f), respecting processing a chemical substance as part of an article, remains applicable.
