2018-24380. Significant New Use Rules on Certain Chemical Substances

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

EPA is proposing significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for 66 chemical substances which were the subject of premanufacture notices (PMNs). The chemical substances are subject to Orders issued by EPA pursuant to section 5(e) of TSCA. This action would require persons who intend to manufacture (defined by statute to include import) or process any of these 66 chemical substances for an activity that is proposed as a significant new use to notify EPA at least 90 days before commencing that activity. The required notification initiates EPA's evaluation of the intended use 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 with that determination.

DATES:

Comments must be received on or before December 31, 2018.

SUPPLEMENTARY INFORMATION:

I. General Information

A. Does this action apply to me?

You may be potentially affected by this action if you manufacture, process, or use the chemical substances contained in this proposed rule. The following list of North American Industrial Classification System (NAICS) codes is not intended to be exhaustive, but rather provides a guide to help readers determine whether this document applies to them. Potentially affected entities may include:

• Manufacturers or processors of one or more subject chemical substances (NAICS codes 325 and 324110), e.g., chemical manufacturing and petroleum refineries.

This action may also affect certain entities through pre-existing import certification and export notification rules under TSCA. Chemical importers are subject to the TSCA section 13 (15 U.S.C. 2612) import certification requirements promulgated at 19 CFR 12.118 through 12.127 and 19 CFR 127.28. Chemical importers must certify that the shipment of the chemical substance complies with all applicable rules and orders under TSCA. Importers of chemicals subject to final SNURs must certify their compliance with the SNUR requirements. The EPA policy in support of import certification appears at 40 CFR part 707, subpart B. In addition, any persons who export or intend to export a chemical substance that is the subject of this proposed rule on or after December 17, 2018 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.

B. What should I consider as I prepare my comments for EPA?

1. Submitting CBI. Do not submit this information to EPA through regulations.gov or email. Clearly mark the part or all of the information that you claim to be CBI. For CBI information in a disk or CD-ROM that you mail to EPA, mark the outside of the disk or CD-ROM as CBI and then identify electronically within the disk or CD-ROM the specific information that is claimed as CBI. In addition to one complete version of the comment that includes information claimed as CBI, a copy of the comment that does not contain the information claimed as CBI must be submitted for inclusion in the public docket. Information so marked will not be disclosed except in accordance with procedures set forth in 40 CFR part 2.

2. Tips for preparing your comments. When preparing and submitting your comments, see the commenting tips at http://www.epa.gov/​dockets/​comments.html.

II. Background

A. What action is the Agency taking?

EPA is proposing these SNURs under TSCA section 5(a)(2) for chemical substances that were the subject of PMNs. These proposed SNURs would require persons to notify EPA at least 90 days before commencing the manufacture or processing of a chemical substance for any activity proposed as a significant new use. Receipt of such notices would allow EPA to assess risks that may be presented by the intended uses and, if appropriate, to regulate the proposed use before it occurs. Additional rationale and background to these proposed rules are more fully set out in the preamble to EPA's first direct final SNUR published in the Federal Register issue of April 24, 1990 (55 FR 17376). Consult that preamble for further information on the objectives, rationale, and procedures for SNURs and on the basis for significant new use designations, including provisions for developing test data.

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 four bulleted 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 on the notice, and taken such actions as are required in association with that determination (15 U.S.C. 2604(a)(1)(B)(ii)). As described in Unit V., the general SNUR provisions are found at 40 CFR part 721, subpart A.

C. Applicability of General Provisions

General provisions for SNURs appear in 40 CFR part 721, subpart A. These provisions describe persons subject to the rule, recordkeeping requirements, and exemptions to reporting requirements. Provisions relating to user fees appear at 40 CFR part 700. According to § 721.1(c), persons subject to SNURs must comply with the same SNUN requirements and EPA regulatory procedures as submitters of PMNs under TSCA section 5(a)(1)(A). In particular, these requirements include the information submission requirements of TSCA section 5(b) and 5(d)(1), the exemptions authorized by TSCA section 5(h)(1), (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 significant new use is not likely to present an unreasonable risk of injury or take such regulatory action as is associated with an alternative determination before the manufacture or processing for the significant new use can commence. If EPA determines that the significant new 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.

III. Proposed Significant New Use Determination

Section 5(a)(2) of TSCA states that EPA's determination that a use of a chemical substance is a significant new use must be made after consideration of all relevant factors, including:

• The projected volume of manufacturing and processing of a chemical substance.
• The extent to which a use changes the type or form of exposure of human beings or the environment to a chemical substance.
• The extent to which a use increases the magnitude and duration of exposure of human beings or the environment to a chemical substance.
• The reasonably anticipated manner and methods of manufacturing, processing, distribution in commerce, and disposal of a chemical substance.

In addition to these factors enumerated in TSCA section 5(a)(2), the statute authorizes EPA to consider any other relevant factors.

To preliminarily determine what would constitute a significant new use for the 66 chemical substances that are the subject of these SNURs, EPA considered relevant information about the toxicity of the chemical substances and potential human exposures and environmental releases that may be associated with the conditions of use of the substances, in the context of the four bulleted TSCA section 5(a)(2) factors listed in this unit.

IV. Substances Subject to This Proposed Rule

EPA is proposing significant new use and recordkeeping requirements for 66 chemical substances in 40 CFR part 721, subpart E. In this unit, EPA provides the following information for each chemical substance:

• PMN number.
• Chemical name (generic name, if the specific name is claimed as CBI).
• Chemical Abstracts Service (CAS) Registry number (if assigned for non-confidential chemical identities).
• Basis for the TSCA section 5(e) Order.
• Information identified by EPA that would help characterize the potential health and/or environmental effects of the chemical 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 the SNUR. This information may include testing required in a TSCA section 5(e) Order to be conducted by the PMN submitter, as well as testing not required to be conducted but which would also help characterize the potential health and/or environmental effects of the PMN substance. Any recommendation for information identified by EPA was made based on EPA's consideration of available screening-level data, if any, as well as other available information on appropriate testing for the chemical substance. Further, any such testing identified by EPA that includes testing on vertebrates was made after consideration of available toxicity information, computational toxicology and bioinformatics, and high-throughput screening methods and their prediction models. EPA also recognizes that whether testing/further information is needed will depend on the specific exposure and use scenario in the SNUN. EPA encourages all SNUN submitters to contact EPA to discuss any potential future testing. See Unit VII. for more information.
• CFR citation assigned in the regulatory text section of the proposed rule.

The regulatory text section of each proposed rule specifies the activities that would be designated as significant new uses. Certain new uses, including exceedance of production volume limits (i.e., limits on manufacture volume) and other uses designated in this proposed rule, may be claimed as CBI.

These proposed rules include 66 PMN substances that are subject to Orders issued under TSCA section 5(e)(1)(A) or section 5(f)(3)(A). Each Order is based on one or more of the findings in TSCA section 5(a)(3)(A) or section 5(a)(3)(B): There is insufficient information to permit a reasoned evaluation; in the absence of sufficient information to permit a reasoned evaluation, the activities associated with the PMN substances may present unreasonable risk to health or the environment; the substance is or will be produced in substantial quantities, and enters or may reasonably be anticipated to enter the environment in substantial quantities or there is or may be significant (substantial) human exposure to the substance; presents an unreasonable risk of injury to health or environment. 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, among other things, 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) that is established by EPA to provide adequate protection to human health. In addition to the actual NCEL concentration, the comprehensive NCELs provisions in TSCA section 5(e) Orders, which are modeled after Occupational Safety and Health Administration (OSHA) Permissible Exposure Limits (PELs) provisions, include requirements addressing performance criteria for sampling and analytical methods, periodic monitoring, respiratory protection, and recordkeeping. However, 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 § 721.63 respirator requirements may request to do so under § 721.30. EPA expects that persons whose § 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.

PMN Number: P-15-106

Chemical Name: Alkene reaction and distillation by-products and residues (generic).

CAS Number: Not available.

Effective date of TSCA section 5(e) Order: May 17, 2018.

Basis for TSCA section 5(e) Order: The PMN states that the generic (non-confidential) use of the substance will be as a mining and fuel additive. Based on test data for analogous chemicals, EPA identified concerns for developmental toxicity, irritation to the eyes, mucous membranes, and lungs, and dermal sensitization. EPA predicts toxicity to aquatic organisms may occur at concentrations that exceed 1 part per billion (ppb). The Order was issued under sections 5(a)(3)(B)(ii)(I) and 5(e)(l)(A)(ii)(I) of TSCA, 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 health and the environment. The 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 Order requires:

1. Submit to EPA certain toxicity testing before manufacturing the confidential aggregate production volume specified in the Order;

2. Use of personal protective equipment to prevent dermal exposure where there is a potential for dermal exposure;

3. Use of a National Institute of Occupational Safety and Health (NIOSH) certified respirator with an assigned protection factor (APF) of 10 where there is a potential for inhalation exposure or compliance with a NCEL of 2 mg/m³ as an 8-hour time-weighted average to prevent inhalation exposure;

4. Release of the PMN substance to water without resulting in surface water concentrations that exceed 1 ppb; and

5. Establishment and use of a hazard communication program, including human health precautionary statements on each label and in the Safety Data Sheet (SDS).

The proposed SNUR would designate as a “significant new use” the absence of these protective measures.

Potentially useful information: EPA has determined that certain information about the health and environmental effects of the PMN substance 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 that would be designated by this proposed SNUR. The submitter has agreed not to exceed a certain production volume limit without performing specific developmental toxicity testing. EPA has also determined that the results of acute aquatic toxicity testing would help characterize the potential 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 721.11194.

PMN Number: P-15-726

Chemical name: Oxirane, 2-methyl-, polymer with oxirane, monobutyl ether, monoether with propylene oxide-2-[[3-(triethoxysilyl)propoxy]methyl]oxirane polymer.

CAS Number: 1644400-33-8.

Effective date of TSCA section 5(e) Order: March 7, 2018.

Basis for TSCA section 5(e) Order: The PMN states that the use of the substance will be as a co-polymer for use in adhesives and sealant formulations. Based on the reactivity of the triethoxysilyl group of the PMN substance, EPA identified concerns for respiratory irritation. The Order was issued under TSCA sections 5(a)(3)(B)(ii)(I) and 5(e)(l)(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 health and the environment. To protect against these risks, the Order requires:

1. No manufacturing, processing, or use of the PMN substance in any manner that generates a vapor, dust, mist, or aerosol; and

2. Establishment and use of a hazard communication program, including human health precautionary statements on each label and in the SDS.

The proposed SNUR would designate as a “significant new use” the absence of these protective measures.

Potentially useful information: EPA has determined that certain information about the health effects of the PMN substance 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 designated by this SNUR. EPA has also determined that the results of specific target organ toxicity or pulmonary effects testing would help characterize the potential health effects of the PMN substance. Although the Order does not require this testing, the Order's restrictions remain in effect until the Order is modified or revoked by EPA based on submission of this or relevant information.

PMN Number: P-16-337

Chemical name: Aliphatic acrylate (generic).

CAS Number: Not available.

Effective date of TSCA section 5(e) Order: April 17, 2018.

Basis for TSCA section 5(e) Order: The PMN states that the use of the substance will be as a monomer. Based on analogy to acrylates, EPA has identified concerns for mutagenicity, oncogenicity, developmental, liver, and kidney toxicity, sensitization, irritation/corrosion, and aquatic/terrestrial toxicity. 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 health and the environment. To protect against these risks, the Order requires:

1. Use of personal protective equipment to prevent dermal exposure where there is potential for dermal exposure;

2. Use of a NIOSH-certified respirator with an APF of at least 50 where there is a potential for inhalation exposure;

3. No use of the PMN substance other than as a chemical intermediate;

4. Establishment and use of a hazard communication program, including human health precautionary statements on each label and in the SDS; and

5. No release of the PMN substance resulting in surface water concentrations that exceed 1 ppb.

The proposed SNUR would designate as a “significant new use” the absence of these protective measures.

Potentially useful information: EPA has determined that certain information about the health and environmental effects of the PMN substance 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 proposed SNUR. EPA has also determined that the results of specific pulmonary effects and skin sensitization testing would help characterize the potential health effects of the PMN substance and results of chronic aquatic toxicity testing would help characterize the potential 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 721.11196.

PMN Number: P-16-421

Chemical name: Flue dust, glass manufg. Desulfurization. Definition: The dust produced from the flue gas exhaust cleaning of a glass manufacturing process using carbonate containing substances. It consists primarily of Na2S04, Na2CO3, and Na4(SO4)(CO3).

CAS Number: 1916486-36-6.

Effective date of TSCA section 5(e) Order: April 19, 2018.

Basis for TSCA section 5(e) Order: The PMN states that the use of the PMN substance will be as an additive to facilitate melting of sand during manufacture of glass. EPA identified concerns for reproductive, developmental, renal, neurological, hematological, gastrointestinal, and cardiovascular effects, and cancer, based on the substance containing toxic metal impurities. The Order was issued under sections 5(a)(3)(B)(ii)(I) and 5(e)(l)(A)(ii)(I) of TSCA, 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 Order requires:

1. Use of a NIOSH-certified respirator with an APF of at least 50 where there is a potential for inhalation exposure or when the PMN substance is in a mixture at a concentration below 1.0 percent by weight, an APF of 10;

2. Establishment and use of a hazard communication program, including human health precautionary statements on each label and in the SDS;

3. Not modifying the processes or uses described in the PMN such that occupational exposure is increased;

4. Use of the PMN substance only as a site-limited intermediate;

5. Conducting and reporting to EPA an elemental analysis for the composition of the PMN substance six months after filing the notice of commencement and every six months, at each use site, for three years thereafter; and

6. Conducting and reporting to EPA an elemental analysis each time a change in the manufacturing process could result in the PMN substance possessing a different elemental composition.

The proposed SNUR would designate as a “significant new use” the absence of protective measures 1, 2, 3, 4, and manufacture of the substance with an elemental composition different from that described in the PMN.

Potentially useful information: EPA has determined that certain information about the composition of the PMN substance may be potentially useful to characterize the health 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 proposed SNUR. The submitter has agreed not to manufacture the PMN substance more than 6 months without performing an elemental analysis to characterize the elemental composition of the PMN substance.

PMN Number: P-16-600

Chemical name: Organo-titanate (generic).

CAS number: Not available.

Effective date of TSCA section 5(e) Order: May 23, 2018.

Basis for TSCA section 5(e) Order: The PMN states that the generic (non-confidential) use of the substance will be as an electrolyte. Based on submitted test data and the pH of the PMN substance, EPA identified concerns for mutagenicity, sensitization, irritation to skin, eyes and mucous membranes, and oncogenicity. EPA predicts toxicity to aquatic organisms may occur at concentrations that exceed 35 ppb based on analogy to phenols. The Order was issued under sections 5(a)(3)(B)(ii)(I) and 5(e)(l)(A)(ii)(I) of TSCA, 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 Order requires:

1. Use of personal protective equipment to prevent dermal exposure where there is a potential for dermal exposure;

2. Establishment and use of a hazard communication program, including human health precautionary statements on each label and in the SDS;

3. Manufacturing, processing, or use of the PMN substance only for the confidential use specified in the Order;

4. No processing or use of the PMN substance in application methods that generate a vapor, mist, or aerosol; and

5. No release of the PMN substance to surface waters.

The proposed SNUR would designate as a “significant new use” the absence of these protective measures.

Potentially useful information. EPA has determined that certain information about the health and environmental effects of the PMN substance 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 proposed SNUR. EPA has also determined that the results of specific aquatic toxicity and carcinogenicity tests would help characterize the potential environmental and health effects of the PMN substance. Although the Order does not require these tests, the Order's restrictions will remain in effect until the Order is modified or revoked by EPA based on submission of this or other information.

PMN Number: P-17-7

Chemical name: Dialkyl 7,10-dioxa, dithiahexadeca diene (generic).

CAS Number: Not available.

Effective date of TSCA section 5(e) Order: April 17, 2018.

Basis for TSCA section 5(e) Order: The PMN states that the use of the substance will be as a chemical intermediate. Based on physical chemical properties and that the epoxide may occur as an oxidation product, EPA has concerns for skin and lung sensitization, mutagenicity, oncogenicity, developmental toxicity, male reproductive toxicity, liver toxicity, and kidney toxicity. Based on structure activity relationship (SAR) analysis on analogous neutral organic chemicals, EPA predicts toxicity to aquatic organisms may occur at concentrations that exceed 67 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 and the environment. To protect against these risks, the Order requires:

1. Use of personal protective equipment where there is a potential for dermal exposure;

2. Refrain from manufacturing (including import) the PMN substance for use other than as a chemical intermediate;

3. No manufacturing, processing or use of the substance that would result in inhalation exposures by vapor, dust, mist, or aerosol;

4. No release of the PMN substance resulting in surface water concentrations that exceed 67 ppb; and

5. Establishment and use of a hazard communication program, including human health precautionary statements on each label and in the SDS.

The proposed SNUR would designate as a “significant new use” the absence of these protective measures.

Potentially useful information: EPA has determined that certain information about environmental effects and 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 proposed SNUR. EPA has determined that the results of specific target organ toxicity, carcinogenicity, and acute 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.

PMN Number: P-17-49

Chemical name: Haloalkyl substituted carbomonocycle (generic).

CAS Number: Not available.

Effective date of TSCA section 5(e) Order: March 13, 2018.

Basis for TSCA section 5(e) Order: The PMN states that the generic (non-confidential) use of the substance will be as a starting material for synthesis. EPA has identified concerns for dermal and respiratory sensitization, mutagenicity, oncogenicity, and developmental toxicity based on the potential for the chemical substance to be an alkylating agent. There are also concerns for possible effects on the liver and the chemical substance is expected to be a strong irritant and corrosive to all exposed tissues based on data on analogous chemicals. EPA predicts that the substance will persist in the environment, could bioaccumulate or biomagnify, and could be toxic (PBT). 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 health and the environment. To protect against these risks, the Order requires:

1. Use of personal protective equipment to prevent dermal exposure where there is potential for dermal exposure;

2. Use of a NIOSH certified respirator with an APF of at least 10 where there is potential for inhalation exposure;

3. Use of the confidential engineering controls specified in the Order;

4. Establishment and use of a hazard communication program, including human health precautionary statements on each label and in the SDS;

5. Refraining from domestic manufacture in the United States (i.e., import only);

6. Use of the PMN substance only for the confidential use specified in the Order;

7. No manufacture of the PMN substance beyond an annual production volume specified in the Order;

8. Disposal of the PMN substance only by incineration; and

9. No release of the PMN substance to surface waters.

The proposed SNUR would designate as a “significant new use” the absence of these protective measures.

Potentially useful information: EPA has determined that certain information about the fate and health effects of the PMN substance 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 proposed SNUR. EPA has also determined that the results of specific reproductive/developmental toxicity, genetic toxicity, and fate 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 721.11200.

PMN Numbers: P-17-249, P-17-380, and P-17-381

Chemical names: Amine- and hydroxy-functional acrylic polymer, neutralized (P-17-249), amine- and hydroxy-functional acrylic polymer (generic) (P-17-380), and hydroxy acrylic polymer, methanesulfonates (generic) (P-17-381).

CAS Numbers: Not available.

Effective date of TSCA section 5(e) Order: March 6, 2018.

Basis for TSCA section 5(e) Order: The PMNs state that the generic (non-confidential) use of the PMN substances will be open and non-dispersive. Based on analysis of test data on analogous polycationic polymers, EPA identified potential concerns for lung effects and aquatic toxicity. The Order was issued under TSCA sections 5(a)(3)(B)(ii)(I) and 5(e)(l)(A)(ii)(I), based on a finding that in the absence of sufficient information to permit a reasoned evaluation, the substances may present an unreasonable risk of injury to human health and the environment. The 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 substances are or will be produced in substantial quantities and that the substances 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 substances. To protect against these risks, the Order requires:

1. Use of the PMN substances only for the confidential uses specified in the Order;

2. Use of the confidential engineering controls specified in the Order;

3. No manufacturing or use of the PMN substances with methods that generate a dust, spray, mist, or aerosol;

4. Establishment and use of a hazard communication program, including human health precautionary statements on each label and in the SDS; and

5. Disposal of the PMN substances only by incineration or with onsite pre-treatment of water releases at an onsite waste water treatment plant with at least 96% efficiency.

The proposed SNUR would designate as a “significant new use” the absence of these protective measures.

Potentially useful information. EPA has determined that certain information about the physical-chemical properties, health effects and environmental effects of the PMN substances may be potentially useful to characterize the potential effects of the PMN substances 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 proposed SNUR. EPA has also determined that the results of specific particle size distribution, physical-chemical property, acute and chronic pulmonary toxicity, and acute and chronic aquatic toxicity testing would help characterize the potential human and environmental effects of the PMN substances.

Chemical name: Alkyl perfluorinated acryloyl ester (generic).

CAS Number: Not available.

Effective date of TSCA section 5(e) Order: April 26, 2018.

Basis for TSCA section 5(e) Order: The PMN states that the generic (non-confidential) use of the substance will be as a low refractive index coating. Based analysis of test data on an analogue, EPA identified concerns for liver toxicity, blood toxicity, and male reproductive toxicity for the potential degradant product. EPA predicts environmental toxicity from the effects of the potential degradation products based on analogue test data. EPA predicts that the substance will persist in the environment, could bioaccumulate or biomagnify, and could be toxic (PBT). The Order was issued under sections 5(a)(3)(B)(ii)(I) and 5(e)(l)(A)(ii)(I) of TSCA, 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 health and the environment. To protect against these risks, the Order requires:

1. Refraining from domestic manufacture in the United States (i.e., import only);

2. No manufacture of the PMN substance beyond a confidential maximum annual manufacture (which includes import) volume; and

3. Use the PMN substance only for the confidential uses specified in the Order. The proposed SNUR would designate as a “significant new use” the absence of these protective measures.

Potentially useful information. EPA has determined that certain information about the environmental fate of the PMN substance may be potentially useful to characterize the potential 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 proposed SNUR. EPA has also determined that the results of specific characterization, fate, and bioaccumulation testing would help characterize the potential health and environmental effects of the PMN substance. Although the Order does not require these tests, the Order's restrictions will remain in effect until the Order is modified or revoked by EPA based on submission of this or relevant information.

Basis for TSCA section 5(e) Order: The PMNs state that the use of the substances is for oil and gas well performance or monitoring well performance. Based on test data for a structurally analogous chemical and physical/chemical properties, EPA has identified concerns for reproductive toxicity, developmental toxicity, and neurotoxicity (ataxia), lung effects, and skin irritation. Based on SAR analysis for analogous chemicals, predicts toxicity to aquatic organisms may occur at concentrations that exceed 8 ppb for certain PMN substances and 460 ppb for certain other PMN substances. 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 substances may present an unreasonable risk of injury to health and environment. To protect against these risks, the Order requires:

1. Refrain from using the PMN substances other than for oil and gas well performance or monitoring well performance;

2. Submit to EPA certain toxicity testing before exceeding the specified confidential production volume limits in the Order;

3. No manufacture of the PMN substances beyond an annual confidential production volume specified in the Order;

4. Use of personal protective equipment to prevent dermal exposure where there is a potential for dermal exposure;

5. Use of engineering controls as specified in the Order;

6. Use of a NIOSH certified respirator with an APF of 50 where there is a potential for inhalation exposure or compliance with a NCEL of 0.0184 mg/m³ as an 8-hour time-weighted average to prevent inhalation exposure for P-17-414 to 418, P-17-420 to 422, and P-17-450;

7. Establishment and use of a hazard communication program, including human health precautionary statements on each label and in the SDS;

8. Limit the amount of the PMN substances handled at processing and use sites as specified in the Order;

9. Limit manufacturing and use to liquid formulations for P-17-441 to 442 and P-17- 444 to 449;

Effective date of TSCA section 5(e) Order: May 7, 2018.

Basis for TSCA section 5(e) Order: The PMNs state the use of the substances will be as tracer chemicals used as a tracer in water solution, or in a solid blend with polymer, or in a solid proppant bead form to measure flow in deep oil-bearing or gas-bearing strata. Based on test data for an analogous chemical, and physical/chemical properties, EPA has identified toxicity concerns for reproductive toxicity, developmental toxicity, neurotoxicity (ataxia), lung effects, and skin irritation. Based on SAR analysis of test data, EPA identified ecotoxicity hazards at concentrations that exceed 300 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 health and the environment. To protect against these risks, the Order requires:

1. Refrain from manufacturing (excluding import) the PMN substances in the United States;

2. Refrain from using the PMN substances other than as tracers in aqueous solution, or in a solid blend with polymer, or in a solid proppant bead form to measure flow in deep oil-bearing or gas-bearing strata;

3. Limit the amount of the PMN substances handled at processing and use sites to no more than 50 kg/day/site in aggregate for the solid formulations that generate a dust;

4. Provide personal protective equipment to its workers to mitigate dermal exposure to the PMN substances where there is potential for dermal exposure;

5. Establishment and use of a hazard communication program, including human health precautionary statements on each label and in the SDS; and

6. No release of the PMN substances resulting in surface water concentrations that exceed 300 ppb;

The proposed SNUR would designate as a “significant new use” the absence of these protective measures.

Potentially useful information: EPA has determined that certain information about the health effects of the PMN substances may be potentially useful to characterize the effects of the PMN substances 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 proposed SNUR. EPA has determined that the results of pulmonary effects, reproductive/developmental toxicity testing and acute aquatic toxicity testing would help characterize the potential health and environmental effects of the PMN substances. Although the Order does not require this testing, 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 721.11217.

PMN Numbers: P-17-434 and P-17-443

Chemical name: Benzoic acid, 2,3,6-trifluoro, sodium salt (1:1).

CAS Number: 1803845-07-9.

Effective date of TSCA section 5(e) Orders: May 11, 2018.

Basis for TSCA section 5(e) Orders: PMN P-17-434 states that the use of the substance is as a tracer chemical (1) used as a tracer in water solution, (2) when in a solid blend with polymer, or (3) in a solid proppant bead form, all to measure flow in deep oil or gas bearing strata. PMN P-17-443 states that the generic (non-confidential) use of the substance will be to monitor well performance. Based on test data for a structurally analogous chemical and physical/chemical properties, EPA has identified concerns for reproductive toxicity, development toxicity, and neurotoxicity (ataxia), lung effects, and skin irritation. The Orders were issued for 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. To protect against these risks, the Orders require:

1. Submission of certain toxicity testing before exceeding the confidential production volume limit in the Order for P-17-443;

2. Manufacture the PMN substance only as a liquid formulation with the engineering controls specified in the Order for P-17-443;

3. Refrain from using the PMN substance other than as a tracer in aqueous solution, a solid blend with polymer, or a solid proppant bead form to measure flow in deep oil-bearing or gas-bearing strata (non-confidential uses specified in the Order for P-17-434), or for the confidential use specified in the Order for P-17-443. The Order for P-17-434 allows processing and use of solid forms of the PMN substance but no more than 50 kg/site/day for those forms that generate a dust. Other manufacturers and processors would need to submit a SNUN to manufacture or process solid forms of the PMN substance.

4. Use of personal protective equipment to mitigate dermal exposure to the PMN substance where there is potential for dermal exposure; and

5. Establishment and use of a hazard communication program, including human health precautionary statements on each label and in the SDS.

The proposed SNUR would designate as a “significant new use” the absence of these protective measures.

Potentially useful information: EPA has determined that certain information about the health effects of the PMN substance 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 proposed SNUR. The submitter for P-17-443 has agreed not to exceed a certain aggregated production volume limit without performing specific pulmonary effects testing. EPA has also determined that the results of pulmonary effects and reproductive/developmental toxicity testing would help characterize the potential health effects of the PMN substance. Although the Order does not require this testing, 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 citations: 40 CFR 721.11218.

PMN Number: P-18-3

Chemical name: Fatty acids, diesters with dihydroxyalkane, fatty acids, esters with dihydroxyalkane (generic).

CAS number: Not available.

Effective date of TSCA section 5(e) Order: April 10, 2018.

Basis for TSCA section 5(e) Order: The PMN states that the use of the substance will be as a lubricant for metal working applications. Based on SAR analysis of test data on analogous esters, EPA has identified concerns for sensitization and skin and eye irritation. 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 PMN substance may present an unreasonable risk of injury to health and the environment. To protect against these risks, the Order requires:

1. Provide personal protective equipment to its workers to prevent dermal exposure where there is potential for dermal exposure; and

2. Establishment and use of a hazard communication program, including human health precautionary statements on each label and in the SDS.

The proposed SNUR would designate as a “significant new use” the absence of these protective measures.

Potentially useful information: EPA has determined that certain information about the health effects of the PMN substance 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 proposed SNUR. EPA has also determined that the results of specific sensitization testing would help characterize the potential health effects of the PMN substance. Although the Order does not require this test, 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 721.11219.

PMN Number: P-18-22

Chemical Name: Substituted carbomonocycle, polymer with halo substituted heteromonocycle and polyoxyalkylene polymer with alkylenebis (isocyanatocarbomonocycle) bis (carbomonocycledicarboxylate), reaction products with alkylamines, hydrolyzed (generic).

CAS Number: Not available.

Effective date of TSCA section 5(e) Order: April 20, 2018.

Basis for TSCA section 5(e) Order: The PMN states that the use of the substance will be used as a primer coating used for corrosion protection. Based on the physical/chemical properties of the PMN substance, available PMN data, and comparing the substance to structurally analogous chemical substances, EPA identified concerns for dermal and ocular irritation and sensitization for the low molecular weight fraction of the PMN substance. EPA also identified concerns for ecotoxicity if the substance was manufactured differently. The Order was issued under TSCA sections 5(a)(3)(B)(ii)(I) and 5(e)(l)(A)(ii)(I) of TSCA, 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 Order requires:

1. Refraining from domestic manufacture in the United States (i.e., import only);

2. Use of the PMN substance only for primer coating for corrosion protection;

3. Import the PMN substance with an average molecular weight greater than 1026 daltons and with low weight fractions no more than 15.3% less than 500 daltons and 25% less than 1000 daltons;

4. Use of personal protective equipment where there is a potential for dermal exposure;

5. Use of a NIOSH-certified respirator with an APF of at least 50 where there is a potential for inhalation exposure; and

6. Establishment and use of a hazard communication program, including human health precautionary statements on each label and in the SDS.

The proposed SNUR would designate as a “significant new use” the absence of these protective measures.

Potentially useful information: EPA has determined that certain information about environmental effects and 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 proposed SNUR. EPA has also determined that the results of skin sensitization, fate property testing, and acute 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 other relevant information.

CFR citation: 40 CFR 721.11220.

V. Rationale and Objectives of the Proposed Rule

A. Rationale

During review of the PMNs submitted for the chemical substances that are subject to these proposed SNURs, EPA concluded that for all 66 chemical substances 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. 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).

B. Objectives

EPA is proposing these SNURs for specific chemical substances which have undergone premanufacture review because the Agency wants to achieve the following objectives with regard to the significant new uses designated in this rule:

• EPA would receive notice of any person's intent to manufacture or process a listed chemical substance for the described significant new use before that activity begins.
• EPA would have an opportunity to review and evaluate data submitted in a SNUN before the notice submitter begins manufacturing or processing a listed chemical substance for the described significant new use.
• EPA would be able to either determine that the prospective manufacture or processing is not likely to present an unreasonable risk, or to take necessary regulatory action associated with any other determination, before the described significant new use of the chemical substance occurs.
• EPA 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).

Issuance of a SNUR for a chemical substance does not signify that the chemical substance is listed on the TSCA Chemical Substance Inventory (TSCA Inventory). Guidance on how to determine if a chemical substance is on the TSCA Inventory is available on the internet at http://www.epa.gov/​opptintr/​existingchemicals/​pubs/​tscainventory/​index.html.

VI. Applicability of the Proposed Significant New Use Designation

To establish a significant new use, EPA must determine that the use is not ongoing. The chemical substances subject to this proposed rule have undergone premanufacture review. In cases where EPA has not received a notice of commencement (NOC) and the chemical substance has not been added to the TSCA Inventory, no person may commence such activities without first submitting a PMN. Therefore, for chemical substances for which an NOC has not been submitted EPA concludes that the designated significant new uses are not ongoing.

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 all of the 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 42 of the 66 chemical substances subject to this proposed rule have been claimed as confidential and EPA has not received any post-PMN bona fide submission (per §§ 720.25 and 721.11) 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 November 15, 2018 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 developing this proposed rule, EPA has recognized that, given EPA's general practice of posting proposed rules on its website a week or more in advance of Federal Register publication, this objective could be thwarted even before Federal Register publication of the proposed rule.

Persons who begin 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.

VII. Development and Submission of Information

EPA recognizes that TSCA section 5 does not require developing any particular new information (e.g., generating test data) before submission of a SNUN. There is an exception: development of test data is required where the chemical substance subject to the SNUR is also subject to a rule, order or consent agreement under TSCA section 4 (see TSCA section 5(b)(1)).

In the absence of a TSCA section 4 test rule covering the chemical substance, persons are required only to submit information in their possession or control and to describe any other information 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. Unit IV. lists potentially useful information identified by EPA that would help characterize the potential health and/or environmental effects of the PMN/SNUN substance for all of the listed SNURs. EPA recognizes that the 2016 Lautenberg Amendments have led to modifications in our approach to testing requirements, including an increased consideration of alternatives to vertebrate testing. Descriptions of tests/information needs are provided for informational purposes only and EPA strongly encourages persons, before performing any testing, to consult with the Agency pertaining to protocol selection. Pursuant to TSCA section 4(h), which pertains to reduction of testing in vertebrate animals, EPA encourages consultation 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 (OECD) test guidelines are available from the OECD Bookshop at http://www.oecdbookshop.org or SourceOECD at http://www.sourceoecd.org.

In certain of the TSCA section 5(e) Orders for the chemical substances that would be regulated under this proposed rule, EPA has established production limits in view of the lack of data on the potential health and environmental risks that may be posed by the significant new uses or increased exposure to the chemical substances. These limits cannot be exceeded unless the PMN submitter first submits the results of specified tests that would permit a reasoned evaluation of the potential risks posed by these chemical substances. Listings of the tests specified in the TSCA section 5(e) Orders are included in Unit IV. The proposed SNURs contain the same production limits as the TSCA section 5(e) Orders. Exceeding these production limits is defined as a significant new use. Persons who intend to exceed the production limit must notify the Agency by submitting a SNUN at least 90 days in advance of commencement of non-exempt commercial manufacture or processing 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.

Any request by EPA for the testing described in the Orders was made based on EPA's consideration of available screening-level data, if any, as well as other available information on appropriate testing for the PMN substances. Further, any such testing/information request on the part of EPA that includes testing on vertebrates was made after consideration of available toxicity information, computational toxicology and bioinformatics, and high-throughput screening methods and their prediction models.

The potentially useful information listed in Unit IV. may not be the only means of addressing the potential risks of the chemical substance. EPA recommends that potential SNUN submitters contact EPA early enough so that they will be able to conduct the appropriate tests.

SNUN submitters should be aware that EPA will be better able to evaluate SNUNs which provide detailed information on the following:

• Human exposure and environmental release that may result from the significant new use of the chemical substances.
• Information on risks posed by the chemical substances compared to risks posed by potential substitutes.

VIII. SNUN Submissions

According to § 721.1(c), persons submitting a SNUN must comply with the same notification requirements and EPA regulatory procedures as persons submitting a PMN, including submission of test data on health and environmental effects as described in § 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 § 720.40 and § 721.25. E-PMN software is available electronically at https://www.epa.gov/​reviewing-new-chemicals-under-toxic-substances-control-act-tsca.

IX. Economic Analysis

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 docket under docket ID number EPA-HQ-OPPT-2018-0650.

X. Statutory and Executive Order Reviews

A. Executive Order 12866

This proposed rule would establish SNURs for several new chemical substances that were the subject of PMNs and TSCA section 5(e) Orders. The Office of Management and Budget (OMB) has exempted these types of actions from review under Executive Order 12866, entitled “Regulatory Planning and Review” (58 FR 51735, October 4, 1993).

B. Paperwork Reduction Act (PRA)

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

The information collection requirements related to this proposed rule have already been approved by OMB pursuant to PRA under OMB control number 2070-0012 (EPA ICR No. 574). This action does not impose any burden requiring additional OMB approval. If an entity were to submit a SNUN to the Agency, the annual burden is estimated to average between 30 and 170 hours per response. This burden estimate includes the time needed to review instructions, search existing data sources, gather and maintain the data needed, and complete, review, and submit the required SNUN.

Send any comments about the accuracy of the burden estimate, and any suggested methods for minimizing respondent burden, including through the use of automated collection techniques, to the Director, Collection Strategies Division, Office of Environmental Information (2822T), Environmental Protection Agency, 1200 Pennsylvania Ave. NW, Washington, DC 20460-0001. Please remember to include the OMB control number in any correspondence, but do not submit any completed forms to this address.

C. Regulatory Flexibility Act (RFA)

Pursuant 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 proposed SNUR would not have a significant adverse economic impact on a substantial number of small entities. 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 SNURs covering over 1,000 chemicals, the Agency receives only a small number of notices per year. For example, the number of SNUNs received was seven in Federal fiscal year (FY) 2013, 13 in FY2014, six in FY2015, 10 in FY2016, and 14 in FY2017, and only a fraction of these were from small businesses. In addition, the Agency currently offers relief to qualifying small businesses by reducing the SNUN submission fee from $16,000 to $2,800. This lower fee reduces the total reporting and recordkeeping of cost of submitting a SNUN to about $10,116 for qualifying small firms. Therefore, the potential economic impacts of complying with this proposed SNUR 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 Act (UMRA)

Based on EPA's experience with proposing and finalizing SNURs, State, local, and Tribal governments have not been impacted by these rulemakings, and EPA does not have any reasons to believe that any State, local, or Tribal government will be impacted by this action. 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 UMRA sections 202, 203, 204, or 205 (2 U.S.C. 1501 et seq.).

E. Executive Order 13132

This proposed rule 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 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 action.

G. Executive Order 13045

This proposed rule 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 proposed rule is not expected to affect energy supply, distribution, or use and because this proposed rule is not a significant regulatory action under Executive Order 12866.

I. National Technology Transfer and Advancement Act (NTTAA)

In addition, since this proposed rule would not involve any technical standards, NTTAA section 12(d) (15 U.S.C. 272 note), does not apply to this action.

J. Executive Order 12898

This proposed rule does not entail special considerations of environmental justice related issues as delineated by Executive Order 12898, entitled “Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations” (59 FR 7629, February 16, 1994).
