RIN 2070-AB27


1,3-Propanediamine, N, N'-1,2-ethanediylbis-, Polymer with 2,4,6-
Trichloro-1,3,5-triazine, Reaction Products with N-Butyl-2,2,6,6-
tetramethyl-4-piperidinamine; Modification of Significant New Use Rules

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: EPA is modifying the significant new use rule (SNUR) 
promulgated under section 5(a)(2) of the Toxic Substances Control Act 
(TSCA) for 1,3-propanediamine, N, N'-1,2-ethanediylbis-, polymer with 
2,4,6-trichloro-1,3,5-triazine, reaction products with N-butyl-2,2,6,6-
tetramethyl-4-piperidinamine based on a modification to the TSCA 5(e) 
consent order regulating the substance. EPA is modifying this rule 
based on receipt of toxicity data.

 EFFECTIVE DATE: The effective date of this rule is January 19, 1996.

Assistance Office (7408), Office of Pollution Prevention and Toxics, 
Environmental Protection Agency, Rm. E-543B, 401 M St., SW.,

SUPPLEMENTARY INFORMATION: In the Federal Register of August 15, 1990 
(55 FR 33296), EPA issued a SNUR (FRL-3741-8) establishing significant 
new uses for 1,3-propanediamine, N, N'-1,2-ethanediylbis-, polymer with 
2,4,6-trichloro-1,3,5-triazine, reaction products with N-butyl-2,2,6,6-
tetramethyl-4-piperidinamine based on the section 5(e) consent order 
for the substance. Because of additional data EPA has received for this 
substance, EPA is modifying the SNUR.

I. Background

    The Agency proposed the modification of the SNUR (FRL-4919-6) for 
this substance in the Federal Register of May 30, 1995 (60 FR 28075). 
The background and reasons for the modification of the SNUR are set 
forth in the preamble to the proposed modification. The Agency received 
no public comment concerning the proposed modification. As a result EPA 
is modifying this SNUR.

II. Objectives and Rationale of Modification of the Rule

    During review of the premanufacture notice (PMN) submitted for the 
chemical substance that is the subject of this modification, EPA 
concluded that regulation was warranted under section 5(e) of TSCA 
pending the development of information sufficient to make a reasoned 
evaluation of the health and environmental effects of the substances. 
EPA identified the tests considered necessary to evaluate the risks of 
the substances and identified the protective equipment necessary to 
protect any workers who may be exposed to the substances. The basis for 
such findings is in the rulemaking record referenced in Unit III of 
this preamble. Based on these findings, a section 5(e) consent order 
modification was negotiated with the PMN submitter.

    In light of the petition to modify the consent order and SNUR, the 
90-day subchronic test, the data on structurally similar polycationic 
polymers, and the recalculation of the risk assessment of the PMN 
substances based on information provided by the petitioner, the Agency 
determined that it could no longer support a finding that the PMN 
substance may present an unreasonable risk to human health or the 
environment for the hazard communication and respiratory protection 
requirements in this modification. The modification of SNUR provisions 
for the substances designated herein is consistent with the provisions 
of the section 5(e) order.

III. Rulemaking Record

    The record for the rule which EPA is modifying was established at 
OPPTS-50582. This record includes information considered by the Agency 
in developing this rule and includes the modification to consent orders 
to which the Agency has responded with this modification.
    A public version of the record, without any Confidential Business 
Information, is available in the OPPT Non-Confidential Information 
Center (NCIC) from 12 p.m. to 4 p.m., Monday through Friday, except 
legal holidays. The TSCA NCIC is located in the Northeast Mall Basement 
Rm. B-607, 401 M St., SW., Washington, DC.

IV. Regulatory Assessment Requirements

    EPA is modifying the requirements of this rule by eliminating 
several requirements. Any costs or burdens associated with this rule 
will be reduced when the rule is modified. Therefore, EPA finds that no 
additional assessments of costs or burdens are necessary under 
Executive Order 12866, the Regulatory Flexibility Act (5 U.S.C. 
605(b)), or the Paperwork Reduction Act (44 U.S.C. 3501 et seq.).
