EPA is proposing significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for chemical substances that were the subject of premanufacture notices (PMNs) and are subject to Orders issued by EPA pursuant TSCA. The SNURs require persons who intend to manufacture (defined by statute to include import) or process any of these chemical substances for an activity that is proposed as a significant new use by this rule to notify EPA at least 90 days before commencing that activity. The required notification initiates EPA's evaluation of the use, under the conditions of use for that chemical substance, within the applicable review period. Persons may not commence manufacture or processing for the significant new use until EPA has conducted a review of the notice, made an appropriate determination on the notice, and has taken such actions as are required by that determination.

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 final SNURs must certify 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 proposed rule on or after June 3, 2020 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.
TSCA section 5(a)(2) (15 U.S.C. 2604(a)(2)) authorizes EPA to determine that a use of a chemical substance is a “significant new use.” EPA must make this determination by rule after considering all relevant factors, including the four TSCA section 5(a)(2) factors listed in Unit III. Once EPA determines that a use of a chemical substance is a significant new use, TSCA section 5(a)(1)(B) 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 (15 U.S.C. 2604(a)(1)(B)(i)). TSCA furthermore prohibits such manufacturing or processing from commencing until EPA has conducted a review of the notice, made an appropriate determination, and taken such actions as are required in association with that determination (15 U.S.C. 2604(a)(1)(B) ii)). In the case of a determination other than not likely to present unreasonable risk, the applicable review period must also expire before manufacturing or processing for the new use may commence.
General provisions for SNURs appear in 40 CFR part 721, subpart A. These provisions describe persons subject to the proposed rule, recordkeeping requirements, exemptions to reporting requirements, and applicability of the rule to uses occurring before the effective date of the rule. Provisions relating to user fees appear at 40 CFR part 700. According to 40 CFR 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). 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 must either determine that the use is not likely to present an unreasonable risk of injury under the conditions of use for the chemical substance or take such regulatory action as is associated with an alternative determination before the manufacture or processing for the significant new use can commence. In the case of a determination other than not likely to present unreasonable risk, the applicable review period must also expire before manufacturing or processing for the new use may commence. If EPA determines that the use is not likely to present an unreasonable risk, EPA is required under TSCA section 5(g) to make public, and submit for publication in the Federal Register, a statement of EPA's findings.
The extent to which a use changes the type or form of exposure of human Start Printed Page 26421beings or the environment to a chemical substance.
In determining what would constitute a significant new use for the chemical substances that are the subject of these SNURs, EPA considered relevant information about the toxicity of the chemical substances, likely human exposures and environmental releases associated with possible uses, and the four TSCA section 5(a)(2) factors listed in this unit. These proposed rules include PMN substances that are subject to Orders issued under TSCA section 5(e)(1)(A), as required by the determinations made under TSCA section 5(a)(3)(B). Those Orders require protective measures to limit exposures or otherwise mitigate the potential unreasonable risk. The proposed SNURs would identify as significant new uses any manufacturing, processing, use, distribution in commerce, or disposal that does not conform to the restrictions imposed by the underlying Orders, consistent with TSCA section 5(f)(4).
EPA is proposing significant new use and recordkeeping requirements for certain chemical substances in 40 CFR part 721, subpart E. In this unit, EPA provides the following information for each chemical substance:
Effective date of and basis for the TSCA section 5(e) Order.
These proposed rules include PMN substances that are subject to Orders issued under TSCA section 5(e)(1)(A), as required by the determinations made under TSCA section 5(a)(3)(B). Those Orders require protective measures to limit exposures or otherwise mitigate the potential unreasonable risk. The proposed SNURs would identify as significant new uses any manufacturing, processing, use, distribution in commerce, or disposal that does not conform to the restrictions imposed by the underlying Orders, consistent with TSCA section 5(f)(4).
Where EPA determined that the PMN substance may present an unreasonable risk of injury to human health via inhalation exposure, the underlying TSCA section 5(e) Order usually requires that potentially exposed employees wear specified respirators unless actual measurements of the workplace air show that air-borne concentrations of the PMN substance are below a New Chemical Exposure Limit (NCEL), include requirements addressing performance criteria for sampling and analytical methods, periodic monitoring, respiratory protection, and recordkeeping. No comparable NCEL provisions currently exist in 40 CFR part 721, subpart B, for SNURs. Therefore, for these cases, the individual SNURs in 40 CFR part 721, subpart E, will state that persons subject to the SNUR who wish to pursue NCELs as an alternative to the 40 CFR 721.63 respirator requirements may request to do so under 40 CFR 721.30. EPA expects that persons whose 40 CFR 721.30 requests to use the NCELs approach for SNURs that are approved by EPA will be required to comply with NCELs provisions that are comparable to those contained in the corresponding TSCA section 5(e) Order for the same chemical substance.
Chemical Name: Aromatic amide oxime (generic).
Effective date of TSCA section 5(e) Order: September 6, 2018.
Basis for TSCA section 5(e) Order: The PMN states that the generic (non-confidential) use of the PMN substance will be as an intermediate. EPA identified concerns for mutagenicity based on analysis of test data on analogs. EPA also identified concerns for toxicity to fish based on analysis of test data on the PMN substance. The Order was issued under TSCA sections 5(a)(3)(B)(ii)(I) and 5(e)(I)(A)(ii)(I), based on a finding that in the absence of sufficient information to permit a reasoned evaluation the substance may present an unreasonable risk of injury to human health and the environment. To protect against these risks, the TSCA Order requires:
Use of personal protective equipment (where there is potential for dermal exposure);
Use of the PMN substance only as a chemical intermediate; and
No predictable or purposeful release of a manufacturing, processing, or use stream associated with any use of the PMN substance into the waters of the United States exceeding a surface water concentration of 30 parts per billion (ppb).
Potentially useful information: EPA has determined that certain information may be potentially useful to characterize the effects of the PMN substance in support of a request by the PMN submitter to modify the Order, or if a manufacturer or processor is considering submitting a SNUN for a significant new use that would be designated by this SNUR. EPA has also determined that the results of specific reproductive/developmental testing and chronic aquatic toxicity testing would help characterize the potential human and environmental effects of the PMN substance. Although the Order does not require these tests, the Order's restrictions remain in effect until the Order is modified or revoked by EPA based on submission of this or relevant information.
CFR citation: 40 CFR 721.11466.
Chemical Name: Carbon nanotubes (generic).
Effective Date of TSCA section 5(e) Order: December 17, 2019.
Basis for TSCA section 5(e) Order: The PMN states that the use of the PMN substance will be as a chemical intermediate to manufacture functionalized carbon nanotubes by oxidation with nitric acid; an additive in rubber polymers to improve mechanical/physical/chemical/electrical properties; an additive in resin polymers to improve mechanical/physical/chemical/electrical properties; an additive in metals to improve electrical/thermal properties; an additive in ceramics to improve mechanical/electrical/thermal properties; a semi-conductor, conductive, or resistive element in electronic circuitry and devices; an electric collector element or electrode in energy devices; a photoelectric or thermoelectric conversion elements in energy devices; a catalyst support element or catalytic electrode for use in energy devices; an additive for transparency and conductivity in electronic devices; and an electro-mechanical element in actuator, sensor, or switching devices. Based on carbon nanotube analogues, data submitted for the PMN substance, and comparison to analogous respirable, poorly soluble particulates, EPA identified concerns for Start Printed Page 26422pulmonary toxicity and oncogenicity. A direct final SNUR was issued for this PMN substance on November 17, 2016 (81 FR 81250), and withdrawn on January 19, 2017 (82 FR 6277) in response to the PMN submitter's intent to submit adverse comments, which was a request to modify the original 5(e) Order to add more uses. The Order (as modified) was issued under TSCA sections 5(a)(3)(B)(ii)(I) and 5(e)(1)(A)(ii)(I), based on a finding that in the absence of sufficient information to permit a reasoned evaluation the substance may present an unreasonable risk of injury to human health and the environment. To protect against these risks, the TSCA Order requires:
The proposed SNUR would designate as a “significant new use” in the absence of these protective measures.
Potentially useful information: EPA has determined that certain information about the environmental effects of the PMN substance may be potentially useful in support of a request by the PMN submitter to modify the TSCA Order, or if a manufacturer or processor is considering submitting a SNUN for a significant new use that would be designated by this SNUR. EPA has determined that the results of chronic aquatic toxicity testing, with NOM (natural organic matter) as the dispersant, may be potentially useful to characterize the environmental effects of the PMN substance. Although the TSCA Order does not require these tests, the TSCA Order's restrictions remain in effect until the TSCA Order is modified or revoked by EPA based on submission of this or other relevant information.
CFR citation: 40 CFR 721.11467.
Chemical Name: Aromatic hydrocarbon resin (generic).
Effective date of TSCA section 5(e) Order: October 17, 2018.
Basis for TSCA section 5(e) Order: The PMN states that the use of the PMN substance will be as a sealant for head lamps of cars. EPA identified concern for hydrocarbon pneumonia if the PMN substance is manufactured with a higher proportion of lower molecular weight species during heating. The Order was issued under TSCA sections 5(a)(3)(B)(ii)(I) and 5(e)(I)(A)(ii)(I), based on a finding that in the absence of sufficient information to permit a reasoned evaluation the substance may present an unreasonable risk of injury to human health. To protect against these risks, the TSCA Order requires:
Manufacture of the PMN substance such that the number average molecular weight is at least 1,000 grams per mole; and
Use of the PMN substance only as a hot-melt sealant for motor vehicle lamps.
Potentially useful information: EPA has determined that certain information about the health effects of the PMN substance may be potentially useful in support of a request by the PMN submitter to modify the TSCA Order, or if a manufacturer or processor is considering submitting a SNUN for a significant new use that would be designated by this SNUR. EPA has also determined that the results of specific organ toxicity testing would help characterize the potential human health effects of the PMN substance. Although the Order does not require these tests, the TSCA Order's restrictions remain in effect until the TSCA Order is modified or revoked by EPA based on submission of this or relevant information.
CFR citation: 40 CFR 721.11468.
Chemical Names: Pentaerythritol ester of mixed linear and branched carboxylic acids (generic) (P-17-193, chemical A) and Dipentaerythritol ester of mixed linear and branched carboxylic acids (generic) (P-17-193, chemical B).
Effective Date of TSCA section 5(e) Order: January 8, 2020.
Basis for TSCA section 5(e) Order: The PMN states that the generic (non-confidential) use of the PMN substances will be as a synthetic lubricant for contained use and as an industrial lubricant. Based on analogue data, EPA has identified concerns for reproductive/developmental effects, systemic toxicity, and kidney effects. Based on comparison to analogous esters, EPA predicts drinking water toxicity may occur at concentrations that exceed 330 ppb. The Order was issued under TSCA sections 5(a)(3)(B)(ii)(I) and 5(e)(1)(A)(ii)(I), based on a finding that in the absence of sufficient information to permit a reasoned evaluation, the substance may present an unreasonable risk of injury to human health or the environment. To protect against these risks, the TSCA Order requires:
No predictable or purposeful release of a manufacturing, processing, or use stream associated with any use of the PMN substances into the waters of the United States exceeding a surface water concentration of 330 ppb.
The proposed SNUR would designate as a “significant new use” in the absence this protective measure.
Potentially Useful Information: EPA has determined that certain information about the human health effects of the PMN substances may be potentially useful in support of a request by the PMN submitter to modify the TSCA Order, or if a manufacturer or processor is considering submitting a SNUN for a significant new use that will be designated by this SNUR. EPA has determined that the results of in vitro toxicokinetics/metabolism information, specific target organ toxicity, and reproductive/development toxicity testing may be potentially useful to characterize the human health effects of the PMN substances. Although the TSCA Order does not require these tests, the TSCA Order's restrictions remain in effect until the TSCA Order is modified or revoked by EPA based on submission of this or other relevant information.
CFR citations: 40 CFR 721.11469 (P-17-193, chemical A) and 40 CFR 721.11470 (P-17-193, chemical B).
Chemical name: Alkylheterocyclic amine blocked isocyanate, alkoxysilane polymer (generic).
Basis for TSCA section 5(e) Order: The PMN states that the generic (non-confidential) use of the PMN substance will be as a coating polymer. Based on analysis of test data on reactivity of the methoxy and ethoxy silane moieties as well as the release of methanol, EPA identified concerns for ocular toxicity, irritation to eyes, skin, lung, and mucous membranes. The TSCA Order was issued under TSCA sections 5(a)(3)(B)(ii)(I) and 5(e)(1)(A)(ii)(I), based on a finding that the in the absence of sufficient information to permit a reasoned evaluation the substance may present an unreasonable risk of injury to human health and the Start Printed Page 26423environment. To protect against these risks, the TSCA Order requires:
Use of personal protective equipment including chemically impervious gloves and eye goggles, (where there is potential for dermal exposure);
No use of the PMN substance at a concentration greater than 10% in formulation;
Establishment and use of a hazard communication program, including human health precautionary statements on each label and in the Safety Data Sheet (SDS); and
Use of the PMN substance only for the confidential use allowed in the TSCA Order.
Potentially useful information: EPA has determined that certain information about the health effects of the PMN substance may be potentially useful in support of a request by the PMN submitter to modify the TSCA Order, or if a manufacturer or processor is considering submitting a SNUN for a significant new use that would be designated by this SNUR. EPA has also determined that the results of specific irritation and lung effect testing would help characterize the potential human effects of the PMN substance. Although the TSCA Order does not require these tests, the TSCA Order's restrictions remain in effect until the TSCA Order is modified or revoked by EPA based on submission of this or relevant information.
CFR citation: 40 CFR 721.11471.
Chemical Name: Isocyanic acid, polymethylenepolyphenylene ester, caprolactam- and phenol-blocked.
CAS Number: 2093945-13-0.
Effective Date of TSCA section 5(e) Order: January 13, 2020.
Basis for TSCA section 5(e) Order: The PMN states that the use of the PMN substance will be as a blocked crosslinker for electrical insulation coating used on stators and motors. Based on the release of phenol, EPA has identified concerns for irritation to membranes, blood toxicity, and developmental toxicity. Based on the release of caprolactam, EPA has also identified concerns for eye, skin, and respiratory irritation, skin and respiratory sensitization, lung effects, kidney toxicity, and developmental toxicity. Based on comparison to analogous carbamate esters-phenyl and carbonyl ureas, EPA predicts toxicity to aquatic organisms may occur at concentrations that exceed 1 ppb. The TSCA Order was issued under TSCA sections 5(a)(3)(B)(ii)(I) and 5(e)(1)(A)(ii)(I), based on a finding that in the absence of sufficient information to permit a reasoned evaluation the substance may present an unreasonable risk of injury to human health and the environment. To protect against these risks, the TSCA Order requires:
No modification of the manufacture, processing, or use of the PMN substance in any manner that generates inhalation exposure to phenol or caprolactam; and
No predictable or purposeful release of a manufacturing, processing, or use stream associated with any use of the PMN substance into the waters of the United States exceeding a surface water concentration of 1 ppb.
Potentially Useful Information: EPA has determined that certain information about the human health and environmental effects of the PMN substance may be potentially useful in support of a request by the PMN submitter to modify the TSCA Order, or if a manufacturer or processor is considering submitting a SNUN for a significant new use that will be designated by this SNUR. EPA has determined that the results of aquatic toxicity, developmental toxicity, pulmonary effects, eye damage, skin irritation/corrosion, and skin sensitization testing may be potentially useful to characterize the human health and environmental effects of the PMN substance. Although the Order does not require these tests, the TSCA Order's restrictions remain in effect until the TSCA Order is modified or revoked by EPA based on submission of this or other relevant information.
CFR citation: 40 CFR 721.11472.
Chemical Name: Benzamide, 2-(trifluoromethyl)-.
CAS Number: 360-64-5.
Effective date of TSCA section 5(e) Order: August 20, 2018.

EPA has identified concerns for neurotoxic effects based on analog data. There are concerns for oncogenicity based on test data. To the extent the chemical substance is metabolized, there are concerns for reproductive, developmental and neurotoxicity, lung, neurotoxicity, liver, and kidney effects based on analog data for the potential derivative metabolite. Based on analogous amides, EPA predicts environmental effects may occur at surface water concentrations that exceed 39 parts per billion. The TSCA Order was issued under TSCA sections 5(a)(3)(B)(ii)(I) based on a finding that the substances may present an unreasonable risk of injury to human health or the environment. To protect against these risks, the TSCA Order requires:
No domestic manufacture of the PMN substance;
Use of personal protective equipment (where there is potential for dermal exposure); Establishment and use of a hazard communication program, including human health precautionary statements on each label and in the SDS;
Import for processing and use only as a chemical intermediate, as required by the Order, with no alteration of processes that result in the generation of a dust, mist or aerosol; and
No predictable or purposeful release of a manufacturing, processing, or use stream associated with any use of the PMN substance into the waters of the United States exceeding a surface water concentration of 39 ppb.
Potentially useful information: EPA has determined that certain information about the health and environmental effects of the PMN substance may be potentially useful in support of a request by the PMN submitter to modify the TSCA Order, or if a manufacturer or processor is considering submitting a SNUN for a significant new use that would be designated by this SNUR. EPA has also determined that the results of specific absorption and metabolism testing and chronic aquatic toxicity testing would help characterize the potential human and environmental effects of the PMN substance. Although the TSCA Order does not require these tests, the TSCA Order's restrictions remain in effect until the TSCA Order is modified or revoked by EPA based on submission of this or relevant information.
CFR citation: 40 CFR 721.11473.
Chemical Name: Cashew, nutshell liq. polymer with formaldehyde, phenol and resorcinol.
CAS Number: 2044014-81-3.
Effective date of TSCA section 5(e) Order: October 19, 2018.
Basis for TSCA section 5(e) Order: The PMN states that the use of the substance will be as an additive as a processing aid for automotive tire stock Start Printed Page 26424(tackifier for synthetic automotive tire stock). EPA identified concerns for sensitization based on resorcinol and cashew nutshell oil. The TSCA Order was issued under TSCA sections 5(a)(3)(B)(ii)(I) and 5(e)(I)(A)(ii)(I), based on a finding that in the absence of sufficient information to permit a reasoned evaluation the substance may present an unreasonable risk of injury to human health. The TSCA Order was also issued under TSCA sections 5(a)(3)(B)(ii)(II) and 5(e)(1)(A)(ii)(II), based on a finding that the substance is or will be produced in substantial quantities and that the substance either enters or may reasonably be anticipated to enter the environment in substantial quantities, or there is or may be significant (or substantial) human exposure to the substance. To protect against these risks, the TSCA Order requires:
Submission to EPA of certain toxicity testing within 12 months of submission of a Notice of Commencement or Manufacture or Import (NOC) for the PMN substance;
Use of a NIOSH-certified respirator with an APF of at least 50 (where there is a potential for inhalation exposure); and
Potentially useful information: EPA has determined that certain information about the health effects of the PMN substance may be potentially useful in support of a request by the PMN submitter to modify the Order, or if a manufacturer or processor is considering submitting a SNUN for a significant new use that would be designated by this SNUR. EPA has also determined that the results of specific sensitization testing would help characterize the potential human effects of the PMN substance. The submitter has agreed not to exceed a certain production volume limit without performing an acute aquatic toxicity testing. Although the TSCA Order does not require these tests, the TSCA Order's restrictions remain in effect until the TSCA Order is modified or revoked by EPA based on submission of this or relevant information.

CFR citation: 40 CFR 721.11489.
During review of the PMNs submitted for the chemical substances that are subject to these proposed SNURs, EPA concluded that regulation was warranted under TSCA section 5(e), pending the development of information sufficient to make reasoned evaluations of the health or environmental effects of the chemical substances. The basis for such findings is outlined in Unit IV. Based on these findings, TSCA section 5(e) Orders requiring the use of appropriate exposure controls were negotiated with the PMN submitters. As a general matter, EPA believes it is necessary to follow TSCA section 5(e) Orders with a SNUR that identifies the absence of those protective measures as Significant New Uses to ensure that all manufacturers and processors—not just the original submitter—are held to the same standard.
To identify as significant new uses any manufacturing, processing, use, Start Printed Page 26429distribution in commerce, or disposal that does not conform to the restrictions imposed by the underlying TSCA Orders, consistent with TSCA section 5(f)(4).
When chemical substances identified in this proposed rule are added to the TSCA Inventory, EPA recognizes that, before the rule is effective, other persons might engage in a use that has been identified as a significant new use. However, TSCA section 5(e) Orders have been issued for these chemical substances, and the PMN submitters are prohibited by the TSCA section 5(e) Orders from undertaking activities which would be designated as significant new uses. The identities of 18 of the 24 chemical substances subject to this proposed rule have been claimed as confidential (per 40 CFR 720.85) for a chemical substance covered by this action. Based on this, the Agency believes that it is highly unlikely that any of the significant new uses described in the regulatory text of this proposed rule are ongoing.
Therefore, EPA designates May 4, 2020 as the cutoff date for determining whether the new use is ongoing. The objective of EPA's approach is to ensure that a person cannot defeat a SNUR by initiating a significant new use before the effective date of the final rule.
In the unlikely event that a person began commercial manufacture or processing of the chemical substances for a significant new use identified as of that date would have to cease any such activity upon the effective date of the final rule. To resume their activities, these persons would have to first comply with all applicable SNUR notification requirements and wait until EPA has conducted a review of the notice, made an appropriate determination on the notice, and has taken such actions as are required with that determination.
In the absence of a rule, Order, or consent agreement under TSCA section 4 covering the chemical substance, persons are required only to submit information in their possession or control and to describe any other information known or reasonably ascertainable (40 CFR 720.50). However, upon review of PMNs and SNUNs, the Agency has the authority to require appropriate testing. Unit IV. lists potentially useful information for all SNURs listed here. Descriptions of this information is provided for informational purposes. The potentially useful information identified in Unit IV of the proposed rule will be useful to EPA's evaluation in the event that someone submits a SNUN for the significant new use. Companies who are considering submitting a SNUN are encouraged, but not required, to develop the information on the substance, which may assist with EPA's analysis of the SNUN. EPA strongly encourages persons, before performing any testing, to consult with the Agency. Furthermore, pursuant to TSCA section 4(h), which pertains to reduction of testing on vertebrate animals, EPA encourages dialog with the Agency on the use of alternative test methods and strategies (also called New Approach Methodologies, or NAMs), if available, to generate the potentially useful information. EPA encourages dialogue with Agency representatives to help determine how best the submitter can meet both the data needs and the objective of TSCA section 4(h). To access the OCSPP test guidelines referenced in this document electronically, please go to http://www.epa.gov/​ocspp and select “Test Methods and Guidelines.” The Organisation for Economic Co-operation and Development test guidelines are available from the OECD Bookshop at http://www.oecdbookshop.org or SourceOECD at http://www.sourceoecd.org.
The potentially useful information listed in Unit IV. may not be the only means of addressing the potential risks of the chemical substance. However, submitting a SNUN without any test data or other information may increase the likelihood that EPA will take action under TSCA section 5(e) or 5(f). EPA recommends that potential SNUN submitters contact EPA early enough so that they will be able to conduct the appropriate tests.
EPA has evaluated the potential costs of establishing SNUN requirements for potential manufacturers and processors of the chemical substances subject to this proposed rule. EPA's complete economic analysis is available in the Start Printed Page 26430docket under docket ID number EPA-HQ-OPPT-2019-0596.
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.Start Printed Page 26431
