40 CFR Parts 766 and 799

[OPPTS0940028; FRL094956093]


Technical Amendments to Test Rules and Consent Orders

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: EPA has approved by letter certain modifications to test 
standards and schedules for chemical testing programs under section 4 
of the Toxic Substances Control Act (TSCA). These modifications, 
requested by test sponsors, will be incorporated and codified in the 
respective test regulation or consent order. Because these 
modifications do not significantly alter the scope of a test or 
significantly change the schedule for its completion, EPA approved 
these requests without seeking notice and comment. EPA annually 
publishes a notice describing all of the modifications granted by 
letter for the previous year.
EFFECTIVE DATE: This rule is effective on September 29, 1995.

FOR FURTHER INFORMATION CONTACT: Susan B. Hazen, Director, 
Environmental Assistance Division (7408), Office of Pollution 
Prevention and Toxics, Rm. E09543B, 401 M St., SW., Washington, DC 
20460, (202) 554091404, TDD (202) 554090551, Internet: TSCA-

SUPPLEMENTARY INFORMATION:  EPA issued a rule published in the Federal 
Register of September 1, 1989 (54 FR 36311), amending procedures for 
modifying test standards and schedules for test rules and testing 
consent orders under section 4 of TSCA. The amended procedures allow 
EPA to approve requested modifications which do not alter the scope of 
a test or significantly change the schedule for its completion. These 
modifications are approved by letter without public comment. The rule 
also requires immediate placement of these letters in EPA's public 
files and publication of these modifications in the Federal Register. 
This document includes modifications approved from January 1, 1994, 
through December 31, 1994. For a detailed description of the rationale 
for these modifications, refer to the submitters' letters and EPA's 
responses in the public record for this rulemaking.

I. Discussion of Modifications

    Each chemical discussed in this rule is identified by a specific 
CAS number and docket number. Copies of correspondence relating to 
specific chemical modifications may be found in docket number 
(OPPTS0940028) established for this rule. The following table lists all 
chemical-specific modifications approved from January 1, 1994, through 
December 31, 1994.

    Modifications
    1. Modify sampling schedule.
    2. Change to test substance (form/purity).
    3. Change in non-critical test procedure or condition.
    4. Add satellite group for further testing.
    5. Extend test or protocol deadline, delete test initiation 
date.
    6. Clarify and/or add specific guideline requirement.
    7. Alternate specific guideline requirement approved for certain 
test(s).
    8. CAS No. correction.
    9. Test standard amendment.
    Note: In Sec. 1A766.35(b)(4)(i) changes have been made to four 
existing chemicals and one new submitter is added to the table; 
however, for the convenience of the user, the entire table is being 
revised.

II. Public Record

    EPA has established a public record for this rulemaking (Docket 
number OPPTS0940028). The record includes the information considered by 
EPA in evaluating the requested modifications.
    The record is available for inspection from 12:00 noon to 4 p.m., 
Monday through Friday, except legal holidays, in Rm. NEB09607, 401 M 
St., SW., Washington, DC 20460.

III. Regulatory Assessment Requirements

A. Analyses Under E.O. 12866, and the Unfunded Mandates Act of 1995

    Because the modifications to the subject testing actions do not 
impose any additional requirements, this action is not ``significant'' 
within the meaning of Executive Order 12866 (58 FR 51735, October 4, 
1993), and does not impose any Federal mandate on any State, local, or 
tribal governments or the private sector within the meaning of the 
Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4).

B. Regulatory Flexibility Act

    Pursuant to the Regulatory Flexibility Act (5 U.S.C. 605(b)), it 
has been determined that this action will not have a significant 
economic impact on a significant number of small entities.

C. Paperwork Reduction Act

    The information collection requirements associated with this rule 
have been approved by OMB under the provisions of the Paperwork 
Reduction Act, 44 U.S.C 3501, and have been assigned OMB control number 
2070-0033. EPA has determined that this rule does not change existing 
recordkeeping or reporting requirements nor does it impose any 
additional recordkeeping or reporting requirements.
