        Proposed Modification of Significant New Uses of Certain Chemical Substances

          AGENCY:
          Environmental Protection Agency (EPA).

          ACTION:
          Proposed rule.

          SUMMARY:
          Under section 5(a)(2) of the Toxic Substances Control Act (TSCA) and 40 CFR 721.185, EPA is proposing to amend three significant new use rules (SNURs) to allow certain uses without requiring a significant new use notice (SNUN).  EPA is proposing these amendments based on review of new toxicity test data on one chemical and review of SNUNs for the other two chemicals.  The proposed amended SNURs would continue to require a SNUN for new uses that may involve significant changes in human or environmental exposure.

        II. Background
        A. What Action is the Agency Taking?
        In the Federal Register of January 22, 1998, OPPTS-50628 (63 FR 3393) (FRL-5720-3) EPA issued a SNUR for P-95-1411.  In the Federal Register of August 20, 1998, OPPTS-50632 (63 FR 44562) (FRL-5788-7) EPA issued SNURs for P-97-520 and P-97-21.  On January 7, 2000, EPA received SNUNs for P-97-520 and P-97-521. Because of additional data EPA has received for these substances, EPA is proposing to modify the significant new use and recordkeeping requirements under 40 CFR part 721, subpart E.  In this unit, EPA provides a brief description for each substance, including its premanufacture notice (PMN) number, chemical name (generic name if the specific name is claimed as CBI), CAS number (if assigned), basis for the modification of the TSCA section 5(e) consent order for the substance, and the CFR citation. Further background information for the substance is contained in Unit I.B.2 of this document.

          PMN Number P-95-1411

          Chemical name: Propanedioic acid, [(4-methoxyphenyl)methylene]-, bis(1,2,2,6,6-pentamethyl-4-piperdinyl) ester (9CI).

          CAS number: 147783-69-5.

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

          Docket number: OPPTS-50628.

          Basis for revocation of section 5(e) consent order/SNUR modification: Based on the results of a 90-day subchronic oral toxicity study in rats and expected worker exposures,  EPA no longer concludes that the PMN substance may present an unreasonable risk of injury to human health, and consequently revoked the consent order.  EPA is eliminating the SNUR provisions for worker protection, hazard communication, and industrial, commercial, and consumer activities as it no longer finds these provisions necessary to prevent significant changes in human exposure.  The SNUR provisions for release to water will remain as EPA still finds that releases to water could result in significant changes in environmental exposure.

          CFR citation: 40 CFR 721.4589.

          PMN Numbers P-97-520/521 and S-00-397/398

          Chemical name: 2-Piperdinone, 1,3-dimethyl-, (P-97-520/S-00-397); 2-Piperdinone, 1,5-dimethyl-, (P-97-521/S-00-398).

          CAS number: 1690-76-2 (P-97-520/S-00-397); 86917-58-0 (P-97-521/S-00-398).

          Federal Register
          publication date and reference: August 20, 1998 (63 FR 44562).

          Docket number: OPPTS-50632.

          Basis for section 5(e) consent order/SNUR modification: In response to the original two PMNs for these substances, EPA issued a TSCA section 5(e) consent order based on a finding that  these substances would be produced in substantial quantities and there may be significant or substantial human exposure to the substances.  Based on information from the two SNUNs for these same chemicals from the original PMN submitter, EPA issued a modified TSCA section 5(e) consent order to allow the new uses with certain precautionary restrictions under section 5(e)(1)(A)(i), 5(e)(1)(A)(ii)(I), and 5(e)(1)(A)(ii)(II) of TSCA, based on a finding that these substances may present an unreasonable risk of injury to human health, that the PMN substances will be produced in substantial quantities, and there may be significant or substantial environmental and human exposure to the substances.  EPA is hereby proposing to modify these two SNURs to allow other manufacturers and processors to engage in those new uses provided the protective restrictions are observed.

          Toxicity concerns: Based on structural activity analogy to 2-piperdinone, N-methylpyrrolidone, and other similarly analogous substances, there is concern for neurotoxicity, developmental toxicity, and reproductive toxicity.  Additionally, based on chemical-specific toxicity data, there is concern for systemic toxicity and developmental toxicity.

          Recommended testing: EPA has determined that a chronic toxicity study (40 CFR 798.3260 or OPPTS 870.4100 test guideline) and a reproduction/fertility effects study (40 CFR 798.4700 or OPPTS 870.3800 test guideline) would help to characterize the health effects of the substances.  EPA has also determined that an inherent biodegradability study in soil (OPPTS 835.3300 test guideline), anerobic biodegradation of organic chemicals (OPPTS 835.3400 test guideline),  fish acute toxicity study (40 CFR 797.1400 or OPPTS 850.1075 test guideline (public draft)), and a daphnid acute toxicity study (40 CFR 797.1300 or OPPTS 850.1010 test guideline (public draft)) would help characterize the environmental effects of the PMN substance. The PMN submitter has agreed to conduct the environmental effects test before exceeding the production volume limit.

          CFR citations: 40 CFR 721.6175 (P-97-520/S-00-397);  40 CFR 721.6176 (P-97-521/S-00-398).
        B. What is the Agency's Authority for Taking this Action?
        TSCA section 5(a)(2) and 40 CFR part 721 authorize 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 section 5(a)(2) of TSCA. Once EPA promulgates a rule designating “significant new uses” for a given chemical substance, section 5(a)(1)(B) of TSCA requires persons to submit a notice to EPA at least 90 days before they manufacture, import, or process the substance for that use. The mechanism for reporting under this requirement is established under 40 CFR 721.5.
        Section 5(a)(1) of TSCA (15 U.S.C. 2604(a)(1)) and its implementing regulations at 40 CFR parts 720 and 721 require that any person intending to manufacture a new chemical substance, or to manufacture or process any chemical substance for a significant new use, must give EPA 90-days advance written notice in the form of a PMN or SNUN, respectively.
        Upon reviewing those notices, if EPA makes certain determinations regarding potential exposures and risks that may be presented by the activities associated with the chemical, EPA may regulate the chemical by issuing an order under TSCA section 5(e) and/or a SNUR under TSCA section 5(a)(2) and 40 CFR part 721.  The TSCA section 5(e) order governs only the entity who submitted the PMN, whereas the section 5(a)(2) SNUR applies to all manufacturers and processors of the same chemical.
        EPA may respond to SNUNs by issuing or modifying a TSCA section 5(e) consent order and/or amending the SNUR promulgated under TSCA section 5(a)(2).  Amendment of the SNUR will often be necessary to allow companies other than the SNUN submitter to engage in the newly authorized use(s), because even after a manufacturer submits a SNUN and the review period expires, processors of the same substance still must submit a SNUN before engaging in the significant new use.  Provisions regarding EPA's authority to modify or revoke SNUR requirements appear at 40 CFR 721.185.
        EPA responded to PMN P-95-1411 by issuing a TSCA section 5(e) consent order and TSCA section 5(a)(2) SNUR to address concerns for both human health and the environment.  Based on data from a 90-subchronic oral toxicity study in rats, submitted pursuant to the terms of the 5(e) consent order,  EPA however,  no longer concludes that the PMN substance may present an unreasonable risk to human health.  Therefore, EPA has revoked the section 5(e) consent order entirely and, pursuant to TSCA section 5(a)(2) and 40 CFR 721.185, is proposing to amend the SNUR to remove the human health related notice requirements, leaving only the notification requirements related to environmental releases.
        EPA responded to PMNs P-97-520/521 by issuing a TSCA section 5(e) consent order requiring certain testing based on expected substantial human and environmental exposures and  promulgating a TSCA section 5(a)(2) SNUR to address concerns for human health.  In response to SNUNs S-00-397/398 by the same manufacturer proposing new uses for the same chemicals, EPA modified the section 5(e) consent order to allow certain new uses, but with restrictions to mitigate potential risks to human health.  Accordingly, pursuant to TSCA section 5(a)(2) and 40 CFR 721.185, EPA is hereby proposing to amend the corresponding SNURs to modify the significant new uses consistent with the terms of the modified section 5(e) consent order and to provide EPA an opportunity to assess the potential for significant changes in human or environmental exposure.
        C. Applicability of General Provisions

        General provisions for SNURs appear under subpart A of 40 CFR part 721. These provisions describe persons subject to the proposed rule, recordkeeping requirements, exemptions to reporting requirements, and applicability of the proposed rule to uses occurring before the effective date of the final rule. Provisions relating to user fees appear at 40 CFR part 700. Persons subject to this SNUR must comply with the same notice requirements and EPA regulatory procedures as submitters of PMNs under section 5(a)(1)(A) of TSCA. 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 SNUR notice, EPA may take regulatory action under TSCA section 5(e), 5(f), 6, or 7 to control the activities on which it has received the SNUR notice. If EPA does not take action, EPA is required under TSCA section 5(g) to explain in the Federal Register its reasons for not taking action.
        Persons who intend to export a substance identified in a proposed or final SNUR are subject to the export notification provisions of TSCA section 12(b). The regulations that interpret TSCA section 12(b) appear at 40 CFR part 707. Persons who intend to import a chemical substance identified in a final SNUR are subject to the TSCA section 13 import certification requirements, which are codified at 19 CFR 12.118 through 12.127 and 127.28. Such persons must certify that they are in compliance with SNUR requirements. The EPA policy in support of the import certification appears at 40 CFR part 707.
        III. Regulatory Assessment Requirements
        Under Executive Order 12866, entitled Regulatory Planning and Review (58 FR 51735, October 4, 1993), the Office of Management and Budget (OMB) has determined that proposed or final SNURs are not a “significant regulatory action” subject to review by OMB, because they do not meet the criteria in section 3(f) of the Executive Order.
        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 rulemaking. As such, EPA has determined that this regulatory action does not impose any enforceable duty, contain any unfunded mandate, or otherwise have any affect 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 proposed rule does not have tribal implications because it is not expected to have substantial direct effects on Indian Tribes. This  does not significantly or uniquely affect the communities of Indian tribal governments, nor does it involve or impose any requirements that affect Indian Tribes. Accordingly, the requirements of section 3(b) of Executive Order 13084, entitled Consultation and Coordination with Indian Tribal Governments (63 FR 276755, May 19, 1998), do not apply to this proposed rule. Executive Order 13175, entitled Consultation and Coordination with Indian Tribal Governments (65 FR 67249, November 6,  2000), which took effect on January 6, 2001, revokes Executive Order 13084 as of that date. EPA developed this rulemaking, however, during the period when Executive Order 13084 was in effect; thus, EPA addressed tribal considerations under Executive Order 13084. For the same reasons stated for Executive Order 13084, the requirements of  Executive Order 10175 do not apply to this proposed rule either. Nor will this action 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).

        In issuing this proposed rule, EPA has taken the necessary steps to eliminate drafting errors and ambiguity, minimize potential litigation, and provide a clear legal standard for affected conduct, as required by section 3 of Executive Order 12988, entitled Civil Justice Reform (61 FR 4729, February 7, 1996).
        EPA has complied with Executive Order 12630, entitled Governmental Actions and Interference with Constitutionally Protected Property Rights (53 FR 8859, March 15, 1988), by examining the takings implications of this proposed rule in accordance with the “Attorney General's Supplemental Guidelines for the Evaluation of Risk and Avoidance of Unanticipated Takings” issued under the Executive Order.

        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 FR 7629, February 16, 1994).

        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.
        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) Pub. L. 104-113 section 12(d) (15 U.S.C. 272 note), does not apply to this action.

        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 SNUR will not have a significant adverse economic impact on a substantial number of small entities.  The rationale supporting this conclusion is as follows.  A SNUR applies to any person (including small or large entities) who intends to engage in any activity described in the proposed rule as a “significant new use.”  By definition of the word “new,” and based on all information currently available to EPA, it appears that no small or large entities presently engage in such activity.  Since a SNUR only requires that any person who intends to engage in such activity in the future must first notify EPA by submitting a SNUN, no economic impact will even occur until someone decides to engage in those activities.  Although some small entities may decide to conduct such activities in the future, EPA cannot presently determine how many, if any, there may be.  However, EPA's experience to date is that, in response to the promulgation of over 530 SNURs, the Agency has received fewer than 15 SNUNs.  Of those SNUNs submitted, none appear to be from small entities in response to any SNUR.  In addition, the estimated reporting cost for submission of a SNUN is minimal regardless of the size of the firm.  Therefore, EPA believes that the potential economic impact of complying with this SNUR are not expected to be significant or adversely impact a substantial number of small entities.  In a SNUR that published on June 2, 1997 (62 FR 29684) (FRL-5597-1), the Agency presented it's general determination that proposed and final SNURs are not expected to have a significant economic impact on a substantial number of small entities, which was provided to the Chief Counsel for Advocacy of the Small Business Administration.

        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, after initial display in the preamble of the final rule and in addition to its display on any related collection instrument, are listed in 40 CFR part 9.

        The information collection requirements related to this action have already been approved by OMB pursuant to the 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 significant new use notice.
        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, OP Regulatory Information Division (2137), Environmental Protection Agency, 1200 Pennsylvania Ave., NW., Washington, DC 20460. Please remember to include the OMB control number in any correspondence, but do not submit any completed forms to this address.

        This proposed rule is not subject to Executive Order 13211, “Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use” (66 FR 28355, May 22, 2001) because it is not a significant regulatory action under Executive Order 12866.
