Environmental Protection Agency (EPA).
Under the Toxic Substances Control Act (TSCA), EPA is proposing to amend the significant new use rule (SNUR) for the chemical substance identified as ethaneperoxoic acid, 1,1-dimethylpropyl ester, which was the subject of premanufacture notice (PMN) P-85-680. This action would amend the SNUR to allow certain uses without requiring a significant new use notice (SNUN), and would extend SNUN requirements to certain additional uses. EPA is proposing this amendment based on review of new toxicity test data.

A. What action is the agency taking?
In the Federal Register of June 26, 1990 (55 FR 26102), EPA published a final SNUR (codified at § 721.1560 and redesignated as § 721.3020) for the chemical substance identified as ethaneperoxoic acid, 1,1-dimethylpropyl ester (PMN P-85-680), in accordance with the procedures at § 721.160. A SNUR requires persons who intend to manufacture, import, or process the chemical substance for an activity designated as a significant new use to notify EPA at least 90 days before commencing that activity.
EPA is proposing to amend the scope and requirements of the SNUR as detailed in this unit. Because the chemical identity of the chemical substance is no longer confidential, EPA is using the specific chemical name and CAS number to identify the chemical substance. The docket established for this proposed SNUR is available under docket ID number EPA-HQ-OPPT-2012-0864. The docket includes information considered by the Agency in developing the proposed rule and the modified TSCA section 5(e) consent order negotiated with the PMN submitter.
PMN Number P-85-680
Chemical name: Ethaneperoxoic acid, 1,1-dimethylpropyl ester.
CAS number: 690-83-5
Effective date of the TSCA section 5(e) consent order: January 30, 1986.
Federal Register publication date and reference: June 26, 1990 (55 FR 26111).
Basis for modification of the SNUR: The TSCA section 5(e) consent order was issued under sections 5(e)(1)(A)(i) and 5(e)(1)(A)(ii)(II) based on the finding that the chemical substance may present an unreasonable risk of injury to human health. To prevent any unreasonable risk the order required dermal and respiratory protection to exposed workers, establishment of a hazard communication program, limited the specific use of the PMN substance as described in the consent order, and required disposal into a waste disposal well. EPA subsequently modified the consent order to allow disposal by landfill and incineration. The proposed SNUR for this chemical substance is based on and consistent with the new data and findings discussed in the two paragraphs below. The proposed SNUR designates as a “significant new use” any purposeful or predictable releases of the PMN substance in concentrations that exceed 61 parts per billion (ppb) in surface waters.
Human health toxicity: EPA received a petition from a second manufacturer to revoke the SNUR based on toxicity testing on structurally analogous peroxide compounds, conducted after the SNUR was issued. Based on the new data EPA concurred with the finding that the PMN substance did not present a carcinogenicity hazard. EPA has also changed its human health findings for the TSCA new chemicals program peroxide category (http://www.epa.gov/oppt/newchems/pubs/npcchemicalcategories.pdf).
Ecotoxicity concerns: Based on data from ecotoxicity studies on structurally analogous peroxy esters and neutral organic chemicals, also conducted after the SNUR was issued, EPA identified potential environmental concerns if the PMN substance was released to surface waters. The second manufacturer also conducted and submitted the results of an acute algal study on the PMN substance. Based on the submitted ecotoxicity testing for algae and analogue data, EPA predicts toxicity to aquatic organisms may occur at concentrations that exceed 61 ppb of the PMN substance in surface waters.
The Agency concluded, after examining the new human health toxicity information, that its finding under section 5(e)(1)(A)(ii)(I) of TSCA in the original TSCA section 5(e) consent order that certain activities involving the substance may present an unreasonable risk of injury to human health is no longer supported. The Agency also concluded based on the ecotoxicity information, that the PMN substance meets the concern criteria at § 721.170 (b)(4)(i) and (b)(4)(ii).
To conform with these findings, the Agency is proposing the following modifications to the SNUR:
1. Removing the significant new use requirements for protective equipment, hazard communication, and specific uses identified in the consent order.
2. Modifying significant new use requirements for environmental releases by removing notification requirements for disposal, and adding notification requirements for water releases above 61 ppb.
3. Revising the recordkeeping requirements to reflect the modified SNUR requirements.
Recommended testing: EPA has determined that the results of a fish acute toxicity test, freshwater and marine (OPPTS Test Guideline 850.1075) and an aquatic invertebrate acute toxicity test, freshwater daphnids (OPPTS Test Guideline 850.1010) would help characterize the environmental effects of the PMN substance.
CFR citation: 40 CFR 721.3020.
B. What is the agency's authority for taking this action?
Section 5(a)(2) of TSCA (15 U.S.C. 2604(a)(2)) authorizes EPA to determine that a use of a chemical substance is a “significant new use.” EPA must make this determination by rule after considering all relevant factors, including the TSCA section 5(a)(2) factors, listed in Unit III. of this document. Once EPA determines that a use of a chemical substance is a significant new use, TSCA section 5(a)(1)(B) and 40 CFR part 721 requires persons to submit a significant new use notice (SNUN) to EPA at least 90 days before they manufacture, import, or process the chemical substance for that use. Persons who must report are described in § 721.5.
EPA may respond to SNUNs by, among other things, issuing or modifying a TSCA section 5(e) consent order and/or amending the SNUR Start Printed Page 5763promulgated under TSCA section 5(a)(2). Amendment of the SNUR will often be necessary to allow persons other than the SNUN submitter to engage in the newly authorized use(s), because even after a person submits a SNUN and the review period expires, other persons still must submit a SNUN before engaging in the significant new use. Procedures and criteria for modifying or revoking SNUR requirements appear at § 721.185.
III. Significant New Use Determination
Section 5(a)(2) of TSCA states that EPA's determination that a use of a chemical substance is a significant new use must be made after consideration of all relevant factors, including:
- The projected volume of manufacturing and processing of a chemical substance.
- The extent to which a use changes the type or form of exposure to human beings or the environment to a chemical substance.
- The extent to which a use increases the magnitude and duration of exposure of human beings or the environment to a chemical substance.
- The reasonably anticipated manner and methods of manufacturing, processing, distribution in commerce, and disposal of a chemical substance.
In addition to these factors enumerated in TSCA section 5(a)(2), the statute authorizes EPA to consider any other relevant factors.
To determine what would constitute a significant new use for the chemical substance identified as ethaneperoxoic acid, 1,1-dimethylpropyl ester (PMN P-85-680), EPA considered relevant information about the toxicity of the chemical substance, likely human exposures and environmental releases associated with possible uses, taking into consideration the four bulleted TSCA section 5(a)(2) factors listed in this unit.
IV. Rationale for the Proposed Rule
During review of PMN P-85-680, the chemical substance identified as ethaneperoxoic acid, 1,1-dimethylpropyl ester, 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 this chemical substance. The basis for such findings is outlined in Unit II. of this document and in the Federal Register document of June 26, 1990 (55 FR 26102). Based on these findings, a TSCA section 5(e) consent order requiring the use of appropriate exposure controls were negotiated with the PMN submitter. The SNUR provisions for this chemical substance are consistent with the provisions of the original TSCA section 5(e) consent order. This SNUR was promulgated pursuant to § 721.160.
After the review of new test data subsequent to issuance of the TSCA section 5(e) consent order for P-85-680 and associated SNUR (see Unit II.), and consideration of the factors included in TSCA section 5(a)(2) (see Unit III.), EPA determined that the chemical substance meets one or more of the concern criteria in § 721.170(b), but that these criteria are no longer met for the personal protective equipment, hazard communication, and specific use notification requirements. Consequently, EPA is proposing this modification to the SNUR at § 721.3020 according to procedures in §§ 721.160 and 721.185.
V. Applicability of Proposed Rule to Uses Occurring Before Effective Date of the Final Rule
To establish a significant “new” use, EPA must determine that the use is not ongoing. EPA solicits comments on whether any of the uses proposed as significant new uses are ongoing. As discussed in the Federal Register of April 24, 1990 (55 FR 17376), EPA has decided that the intent of section 5(a)(1)(B) of TSCA is best served by designating a use as a significant new use as of the date of publication of the proposed rule, rather than as of the effective date of the final rule. If uses begun after publication of the proposed rule were considered ongoing rather than new, it would be difficult for EPA to establish SNUR notice requirements, because a person could defeat the SNUR by initiating the significant new use before the rule became final, and then argue that the use was ongoing as of the effective date of the final rule.
Thus, any persons who begin commercial manufacture, import, or processing activities with the chemical substances that are not currently a significant new use under the current rule but which would be regulated as a “significant new use” if this proposed rule is finalized, must cease any such activity as of the effective date of the rule if and when finalized. To resume their activities, these persons would have to comply with all applicable SNUR notice requirements and wait until the notice review period, including all extensions, expires.
EPA has promulgated provisions to allow persons to comply with this SNUR before the effective date. If a person were to meet the conditions of advance compliance under § 721.45(h), the person would be considered to have met the requirements of the final SNUR for those activities.
VI. Test Data and Other Information
EPA recognizes that TSCA section 5 does not require the development of any particular test data before submission of a SNUN. There are two exceptions:
1. Development of test data is required where the chemical substance subject to the SNUR is also subject to a test rule under TSCA section 4 (see TSCA section 5(b)(1)).
2. Development of test data may be necessary where the chemical substance has been listed under TSCA section 5(b)(4) (see TSCA section 5(b)(2)).
In the absence of a TSCA section 4 test rule or a TSCA section 5(b)(4) listing covering the chemical substance, persons are required only to submit test data in their possession or control and to describe any other data known to or reasonably ascertainable by them (see § 720.50). However, upon review of PMNs and SNUNs, the Agency has the authority to require appropriate testing. In this case, EPA recommends persons, before performing any testing, to consult with the Agency pertaining to protocol selection. To access the Harmonized Test Guidelines referenced in this document electronically, please go to http://www.epa.gov/ocspp and select “Test Methods and Guidelines.”
The modified TSCA section 5(e) consent order for the chemical substance that would be regulated under this proposed rule does not require submission of the test at any specified time or volume. However, the restrictions on manufacture, import, processing, distribution in commerce, use, and disposal of the PMN substance would remain in effect until the consent order is modified or revoked by EPA based on submission of that or other relevant information. These restricted activities cannot be commenced unless the PMN submitter first submits the results of toxicity tests that would permit a reasoned evaluation of the potential risks posed by this chemical substance. The test specified in the modified TSCA section 5(e) consent order is included in Unit II. The proposed SNUR would contain the same restrictions as the modified TSCA section 5(e) consent order. Persons who intend to commence non-exempt commercial manufacture, import, or processing for those activities proposed as significant new uses would be required to notify the Agency by submitting a SNUN at least 90 days in advance of commencement of those activities.
The recommended testing specified in Unit II. of this document may not be the Start Printed Page 5764only means of addressing the potential risks of the chemical substance. However, SNUNs submitted without any test data may increase the likelihood that EPA will take action under TSCA section 5(e), particularly if satisfactory test results have not been obtained from a prior PMN or SNUN submitter. EPA recommends that potential SNUN submitters contact EPA early enough so that they will be able to conduct the appropriate tests.
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 substance.
- Potential benefits of the chemical substance.
- Information on risks posed by the chemical substance compared to risks posed by potential substitutes.
VII. SNUN Submissions
According to 40 CFR 721.1(c), persons submitting a SNUN must comply with the same notice requirements and EPA regulatory procedures as persons submitting a PMN, including submission of test data on health and environmental effects as described in § 720.50. SNUNs must be on EPA Form No. 7710-25, generated using e-PMN software, and submitted to the Agency in accordance with the procedures set forth in §§ 721.25 and 720.40. E-PMN software is available electronically at http://www.epa.gov/opptintr/newchems.
VIII. Economic Analysis
EPA evaluated the potential costs of establishing SNUN requirements for potential manufacturers, importers, and processors of the chemical substances during the development of the direct final rule. The Agency's complete economic analysis is available in the docket under docket ID number EPA-HQ-OPPT-2012-0864.
IX. Statutory and Executive Order Reviews
A. Executive Order 12866
This proposed rule would modify a SNUR for a chemical substance that is the subject of a PMN and TSCA section 5(e) consent order. The Office of Management and Budget (OMB) has exempted these types of actions from review under Executive Order 12866, entitled Regulatory Planning and Review (58 FR 51735, October 4, 1993).
B. Paperwork Reduction Act
According to the Paperwork Reduction Act (PRA), 44 U.S.C. 3501 et seq., an Agency may not conduct or sponsor, and a person is not required to respond to a collection of information that requires OMB approval under the PRA, unless it has been approved by OMB and displays a currently valid OMB control number. The OMB control numbers for EPA's regulations in title 40 of the CFR, after appearing in the Federal Register, are listed in 40 CFR part 9, and included on the related collection instrument or form, if applicable. EPA has amended the table in 40 CFR part 9 to list the OMB approval number for the information collection requirements contained in this proposed rule. This listing of the OMB control numbers and their subsequent codification in the CFR satisfies the display requirements of PRA and OMB's implementing regulations at 5 CFR part 1320. This Information Collection Request (ICR) was previously subject to public notice and comment prior to OMB approval, and given the technical nature of the table, EPA finds that further notice and comment to amend it is unnecessary.
The information collection requirements related to this action have already been approved by OMB pursuant to PRA under OMB control number 2070-0012 (EPA ICR No. 574). This action would not impose any burden requiring additional OMB approval. If an entity were to submit a SNUN to the Agency, the annual burden is estimated to average between 30 and 170 hours per response. This burden estimate includes the time needed to review instructions, search existing data sources, gather and maintain the data needed, and complete, review, and submit the required SNUN.
Send any comments about the accuracy of the burden estimate, and any suggested methods for minimizing respondent burden, including through the use of automated collection techniques, to the Director, Collection Strategies Division, Office of Environmental Information (2822T), Environmental Protection Agency, 1200 Pennsylvania Ave., NW., Washington, DC 20460-0001. Please remember to include the OMB control number in any correspondence, but do not submit any completed forms to this address.
C. Regulatory Flexibility Act
On February 18, 2012, EPA certified pursuant to section 605(b) of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et seq.), that promulgation of a SNUR does not have a significant economic impact on a substantial number of small entities where the following are true:
1. A significant number of SNUNs would not be submitted by small entities in response to the SNUR.
2. The SNUN submitted by any small entity would not cost significantly more than $8,300.
A copy of that certification is available in the docket for this proposed rule.
This proposed rule is within the scope of the February 18, 2012 certification. Based on the economic analysis discussed in Unit VIII. and EPA's experience promulgating SNURs (discussed in the certification), EPA believes that the following are true:
- A significant number of SNUNs would not be submitted by small entities in response to the SNUR.
- Submission of the SNUN would not cost any small entity significantly more than $8,300. Therefore, the promulgation of the SNUR would not have a significant economic impact on a substantial number of small entities.
D. Unfunded Mandates Reform Act
Based on EPA's experience with proposing and finalizing SNURs, State, local, and Tribal governments have not been impacted by these rulemakings, and EPA does not have any reason to believe that any State, local, or Tribal government would be impacted by this proposed rule. As such, EPA has determined that this proposed rule would not impose any enforceable duty, contain any unfunded mandate, or otherwise have any effect on small governments subject to the requirements of sections 202, 203, 204, or 205 of the Unfunded Mandates Reform Act of 1995 (UMRA) (Pub. L. 104-4).
This action would not have a substantial direct effect on States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132, entitled Federalism (64 FR 43255, August 10, 1999).
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 Start Printed Page 576567249, November 9, 2000), do not apply to this proposed rule.
This action is not subject to Executive Order 13045, entitled Protection of Children from Environmental Health Risks and Safety Risks (62 FR 19885, April 23, 1997), because this is not an economically significant regulatory action as defined by Executive Order 12866, and this action does not address environmental health or safety risks disproportionately affecting children.
This proposed rule is not subject to Executive Order 13211, entitled Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use (66 FR 28355, May 22, 2001), because this action is not expected to affect energy supply, distribution, or use and because this action is not a significant regulatory action under Executive Order 12866.
I. National Technology Transfer and Advancement Act
In addition, since this action does not involve any technical standards, section 12(d) of the National Technology Transfer and Advancement Act of 1995 (NTTAA), Public Law 104-113, section 12(d) (15 U.S.C. 272 note), does not apply to this action.
This action does not entail special considerations of environmental justice related issues as delineated by Executive Order 12898, entitled Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations (59 FR7629, February 16, 1994).Start List of Subjects
