Proposed rule.


EPA is proposing to revoke a significant new use rule (SNUR) promulgated under section 5(a)(2) of the Toxic Substances Control Act (TSCA) for a chemical substance identified generically as substituted ethoxyethylamine phosphonate, which was the subject of premanufacture notice (PMN) P-95-1950. EPA issued a “non-5(e)” SNUR (i.e. SNUR on a substance that is not subject to a TSCA section 5(e) consent order), designating certain activities as significant new uses based on the concern criteria. EPA has received and reviewed new information and test data for the chemical substance and proposes to revoke the SNUR.

I. General Information

A. Does this action apply to me?

You may be potentially affected by this action if you manufacture, import, process, or use the chemical substance contained in this proposed rule. Potentially affected entities may include, but are not limited to:

  • Manufacturers, importers, or processors of the subject chemical substance (NAICS codes 325 and 324110), e.g., chemical manufacturers and petroleum refineries. This listing is not intended to be exhaustive, but rather provides a guide for readers regarding entities likely to be affected by this action. Other types of entities not listed in this unit could also be affected. The North American Industrial Classification System (NAICS) codes have been provided to assist you and others in determining whether this action might apply to certain entities. To determine whether you or your business may be affected by this action, you should carefully examine the applicability provisions in § 721.5. If you have any questions regarding the applicability of this action to a particular entity, consult the technical person listed under FOR FURTHER INFORMATION CONTACT.

This action may also affect certain entities because of import certification and export notification requirements under TSCA. Chemical importers are subject to the TSCA section 13 (15 U.S.C. 2612) import certification requirements promulgated at 19 CFR 12.118 through 12.127; see also 19 CFR 127.28. Chemical importers must certify that the shipment of the chemical substance complies with all applicable rules and orders under TSCA. The EPA policy in support of import certification appears at 40 CFR part 707, subpart B. Importers of the chemical, the subject of this action, would no longer be required to certify compliance with the SNUR requirements if the revocation becomes effective. In addition, if this proposed SNUR revocation becomes effective, persons who export or intend to export the chemical that is the subject of this action would no longer be subject to the TSCA section 12(b) (15 U.S.C. 2611(b)) export notification requirements at 40 CFR part 707, that are currently triggered by the SNUR.

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

1. Submitting CBI. Do not submit this information to EPA through or e-mail. 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 submitting comments, remember to:

i. Identify the document by docket ID number and other identifying information (subject heading, Federal Register date and page number).

ii. Follow directions. The Agency may ask you to respond to specific questions or organize comments by referencing a Code of Federal Regulations (CFR) part or section number.

iii. Explain why you agree or disagree; suggest alternatives and substitute language for your requested changes.

iv. Describe any assumptions and provide any technical information and/or data that you used.

v. If you estimate potential costs or burdens, explain how you arrived at your estimate in sufficient detail to allow for it to be reproduced.

vi. Provide specific examples to illustrate your concerns and suggest alternatives.

vii. Explain your views as clearly as possible, avoiding the use of profanity or personal threats.

viii. Make sure to submit your comments by the comment period deadline identified.

II. Background

A. What action is the agency taking?

In the Federal Register of January 22, 1998 (63 FR 3393) (FRL-5720-3), EPA promulgated a SNUR at 40 CFR 721.6078 for the chemical substance identified generically as substituted ethoxyethylamine phosphonate (PMN P-95-1950). This SNUR designated certain activities as significant new uses based on the environmental effect criteria identified in § 721.170(b)(4)(ii) for analogous polyanionic monomers. EPA has received and reviewed aquatic toxicity test data for the chemical substance and based on its review of these data, EPA now proposes to revoke the SNUR pursuant to § 721.185. In this unit, EPA provides a brief description of this chemical substance, including the PMN number, generic chemical name, the Federal Register publication date and reference, the docket number, the basis for revoking the SNUR under § 721.185, and the CFR citation of the SNUR.

PMN Number P-95-1950

Chemical name: Substituted ethoxyethylamine phosphonate (generic).

CAS number: Not available.

Federal Register publication date and reference: January 22, 1998 (63 FR 3393).

Docket number: OPPTS-50628.

Basis for revocation of SNUR: EPA issued a SNUR for this substance based on the environmental effect criteria at § 721.170(b)(4)(ii) for analogous polyanionic monomers. Subsequently, the PMN submitter petitioned EPA to revoke the SNUR based on the results of submitted aquatic toxicity testing in fish, daphnids, and algae. The aquatic toxicity testing demonstrated that the substance has inherently low toxicity, mitigating EPA's concern for toxicity to aquatic organisms. Therefore, EPA rescinds its finding that releases to water resulting in stream concentrations that exceed 30 parts per billion (ppb) may cause significant adverse environmental effects. Based on available information, the substance no longer meets the concern criteria at § 721.170(b)(4)(ii). Therefore, EPA proposes that the SNUR for this Start Printed Page 27296chemical substance be revoked pursuant to § 721.185(a)(4).

CFR citation: 40 CFR 721.6078.

B. What is the agency's authority for taking this action?

Section 5(a)(2) of TSCA (15 U.S.C. 2604(a)(2)) authorizes EPA to determine that a use of a chemical substance is a “significant new use.” EPA must make this determination by rule after considering all relevant factors, including those listed in TSCA section 5(a)(2). Once EPA determines that a use of a chemical substance is a significant new use, TSCA section 5(a)(1)(B) requires persons to submit a significant new use notice (SNUN) to EPA at least 90 days before they manufacture, import, or process the chemical substance for that use. The mechanism for reporting under this requirement is established under § 721.5.

Upon conclusion of the review for P-95-1950, based on the concern criteria in § 721.170(b)(4)(ii) discussed in Unit II.A., EPA determined that there was a concern for potential environmental effects of the substance at a concentration as low as 30 ppb of the PMN substance in surface waters and promulgated a non-5(e) SNUR for this chemical substance.

Under § 721.185, EPA may at any time revoke a SNUR for a chemical substance which has been added to subpart E of 40 CFR part 721 if EPA makes one of the determinations set forth in § 721.185(a)(1) through (a)(6). Revocation may occur on EPA's initiative or in response to a written request. Under § 721.185(b)(3), if EPA concludes that a SNUR should be revoked, the Agency will propose the changes in the Federal Register, briefly describe the grounds for the action, and provide interested parties an opportunity to comment.

EPA has determined that the criteria set forth in § 721.185(a)(4) have been satisfied for the chemical substance; therefore, EPA is proposing to revoke the SNUR for this chemical substance. The significant new use notification and the recordkeeping requirements at 40 CFR 721.6078 would terminate if and when this proposed revocation becomes effective. In addition, export notification under TSCA section 12(b) and 40 CFR part 707, subpart D triggered by the SNUR would no longer be required.

III. Statutory and Executive Order Reviews

This proposed rule would revoke or eliminate an existing regulatory requirement and does not contain any new or amended requirements. As such, the Agency has determined that this proposed SNUR revocation would not have any adverse impacts, economic or otherwise.

The Office of Management and Budget (OMB) has exempted these types of regulatory actions from review under Executive Order 12866, entitled Regulatory Planning and Review (58 FR 51735, October 4, 1993). This proposed rule does not contain any information collections subject to approval under the Paperwork Reduction Act (PRA), (44 U.S.C. 3501 et seq.). Since this proposed rule eliminates a reporting requirement, the Agency certifies pursuant to section 605(b) of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et seq.), that this SNUR revocation would not have a significant economic impact on a substantial number of small entities.

For the same reasons, this action does not require any action under Title II of the Unfunded Mandates Reform Act of 1995 (UMRA) (Pub. L. 104-4). This proposed rule has neither Federalism implications, because it would not have substantial direct effects 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), nor Tribal implications, because it would not have substantial direct effects on one or more Indian Tribes, on the relationship between the Federal Government and Indian Tribes, or on the distribution of power and responsibilities between the Federal Government and Indian Tribes, as specified in Executive Order 13175, entitled Consultation and Coordination with Indian Tribal Governments (65 FR 67249, November 9, 2000).

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 under Executive Order 12866, and it does not address environmental health or safety risks disproportionately affecting children. It 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. Because 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 involve special considerations of environmental justice related issues as required by Executive Order 12898, entitled Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations (59 FR 7629, February 16, 1994).
