Preliminary Assessment Information and Health and Safety Data 
Reporting; Addition of Chemicals

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: The Interagency Testing Committee (ITC) in its 37th Report to 
EPA revised the Toxic Substances Control Act (TSCA) Section 4(e) 
Priority List by recommending for testing 28 chemical substances. The 
ITC recommendations must be given priority consideration by EPA in 
promulgating test rules. EPA is adding these chemical substances to two 
model information-gathering rules: the TSCA Section 8(a) Preliminary 
Assessment Information Rule (PAIR) and the TSCA Section 8(d) Health and 
Safety Data Reporting Rule. These model rules will require 
manufacturers and importers of the substances identified herein to 
report certain production, use, and exposure-related information, and 
manufacturers, importers, and processors of the listed substances to 
report unpublished health and safety data to EPA. This rule also makes 
certain modifications to a final 

[[Page 7422]]
rule published in the Federal Register of February 9, 1994; the TSCA 
section 8(d) Health and Safety Data Reporting rule.

EFFECTIVE DATE: March 29, 1996.

FOR FURTHER INFORMATION CONTACT:
Susan B. Hazen, Director, TSCA Environmental Assistance Division 
(7408), Office of Pollution Prevention and Toxics, Environmental 
Protection Agency, 401 M St., SW., Rm. E-543, Washington, DC 20460, 
Telephone: (202) 554-1404, TDD: (202) 554-0551, e-mail: TSCA-
H[email protected].

SUPPLEMENTARY INFORMATION: This rule adds 28 chemical substances to the 
PAIR and the section 8(d) Health and Safety Data Reporting Rule. 
Manufacturers, importers, and processors of these chemicals will be 
required to report unpublished health and safety data, and 
manufacturers and importers will be required to report end use, 
exposure, and production volume data to EPA.
    This document also modifies TSCA section 8(d) of a final rule 
published in the Federal Register of February 9, 1994 (59 FR 5956), to 
require submission of ecological effects data for o-sec-butylphenol 
(CAS No. 89-72-5).

I. Background

    Section 4(e) of TSCA established the ITC and authorized it to 
recommend to EPA chemical substances and mixtures (chemicals) to be 
given priority consideration in proposing test rules under section 4. 
For some of these chemicals, the ITC may designate that EPA must 
respond to its recommendations within 12 months. In this time, EPA must 
either initiate a rulemaking to test the chemical or publish in the 
Federal Register its reasons for not doing so.
    On November 22, 1995, EPA announced the receipt of the 37th Report 
of the ITC, and it was then published in the Federal Register of 
February 2, 1996 (61 FR 4188). The 37th Report revises the Committee's 
priority list of chemicals by recommending the addition of 28 chemical 
substances for testing to the section 4(e) priority list.
    This rule adds 28 substances to the section 8(a) Preliminary 
Assessment Information Reporting Rule PAIR and the section 8(d) Health 
and Safety Data Reporting Rule. These two rules are model information 
gathering rules which assist the ITC in making testing recommendations 
and aid EPA in responding to the ITC recommendations.
    EPA issued the PAIR under section 8(a) of TSCA (15 U.S.C. 2607(a)), 
and it is codified at 40 CFR part 712. This model section 8(a) rule 
establishes standard reporting requirements for manufacturers and 
importers of the chemicals listed in the rule at 40 CFR 712.30. These 
manufacturers and importers are required to submit a one-time report on 
general volume, end use, and exposure-related information using the 
Preliminary Assessment Information Manufacturer's Report (EPA Form 
7710-35). EPA uses this model section 8(a) rule to gather current 
information on chemicals of concern quickly.
    EPA issued the model Health and Safety Data Reporting Rule under 
section 8(d) of TSCA (15 U.S.C. 2607(d)), and it is codified at 40 CFR 
part 716. The section 8(d) model rule requires past, current, and 
prospective manufacturers, importers, and processors of listed 
chemicals to submit to EPA copies and lists of unpublished health and 
safety studies on the listed chemicals that they manufacture, import, 
or process. These studies provide EPA with useful information and have 
provided significant support for EPA's decisionmaking under TSCA 
sections 4, 5, 6, 8, and 9.
    These model rules provide for the automatic addition of ITC 
priority list chemicals. Whenever EPA announces the receipt of an ITC 
report, EPA may, at the same time without further notice and comment, 
amend the two model information-gathering rules by adding the 
recommended chemicals. The amendment adding these chemicals to the PAIR 
and the Health and Safety Data Reporting Rule becomes effective 30 days 
after publication in the Federal Register.

II. Chemicals To Be Added

    In its 37th Report to EPA, the ITC recommended adding 28 
alkylphenols and alkylphenol ethoxylates to the section 8(a) PAIR and 
the section 8(d) Health and Safety Data Reporting Rule. While 28 
chemical substances are identified in the regulatory text, 34 CAS 
numbers are listed. Two chemical substances, branched 4-nonyphenol 
(mixed isomers) and (1,1,3,3-tetramethylbutyl)phenol (mixed isomers) 
are characterized with multiple CAS numbers.
    For a complete listing of the substances being added to the section 
8(d) model rule and the PAIR, see the regulatory text of this document.
    In response to the data needs of EPA and the Department of 
Interior, TSCA section 8(d) reporting requirements for o-sec-
buytlphenol (CAS No. 89-72-5) are being amended to require submission 
of ecological effects data (59 FR 5956, February 9, 1994).

III. Reporting Requirements

A. Preliminary Assessment Information Rule

    All persons who manufactured or imported the chemical substances 
named in this rule during their latest complete corporate fiscal year 
must submit a Preliminary Assessment Information Manufacturer's Report 
(EPA Form No. 7710-35) for each manufacturing or importing site at 
which they manufactured or imported a named substance. A separate form 
must be completed for each substance and submitted to the Agency no 
later than May 28, 1996. Persons who have previously and voluntarily 
submitted a Manufacturer's Report to the ITC or EPA may be able to 
submit a copy of the original Report to EPA or to notify EPA by letter 
of their desire to have this voluntary submission accepted in lieu of a 
current data submission. See Sec. 712.30(a)(3).
    Details of the reporting requirements, the basis for exemptions, 
and a facsimile of the reporting form, are provided in 40 CFR part 712. 
Copies of the form are available from the TSCA Environmental Assistance 
Division at the address listed under FOR FURTHER INFORMATION CONTACT.

B. Health and Safety Data Reporting Rule

    Listed below are the general reporting requirements of the section 
8(d) model rule.
    1. Persons who, in the 10 years preceding the date a substance is 
listed, either have proposed to manufacture, import, or process, or 
have manufactured, imported, or processed, the listed substance must 
submit to EPA; A copy of each health and safety study which is in their 
possession at the time the substance is listed.
    2. Persons who, at the time the substance is listed, propose to 
manufacture, import, or process; or are manufacturing, importing, or 
processing the listed substance must submit to EPA:
    a. A copy of each health and safety study which is in their 
possession at the time the substance is listed.
    b. A list of health and safety studies known to them but not in 
their possession at the time the substance is listed.
    c. A list of health and safety studies that are ongoing at the time 
the substance is listed and are being conducted by or for them.
    d. A list of each health and safety study that is initiated after 
the date the substance is listed and is conducted by or for them.

[[Page 7423]]

    e. A copy of each health and safety study that was previously 
listed as ongoing or subsequently initiated and is now complete--
regardless of completion date.
    3. Persons who, after the time the substance is listed, propose to 
manufacture, import, or process the listed substance must submit to 
EPA:
    a. A copy of each health and safety study which is in their 
possession at the time they propose to manufacture, import, or process 
the listed substance.
    b. A list of health and safety studies known to them but not in 
their possession at the time they propose to manufacture, import, or 
process the listed substance.
    c. A list of health and safety studies that are ongoing at the time 
they propose to manufacture, import, or process the listed substance, 
and are being conducted by or for them.
    d. A list of each health and safety study that is initiated after 
the time they propose to manufacture, import, or process the listed 
substance, and is conducted by or for them.
    e. A copy of each health and safety study that was previously 
listed as ongoing or subsequently initiated and is now complete--
regardless of the completion date.
    The bulk of reporting is required at the time the substance is 
listed. Persons described in categories 1 and 2 do all or most of their 
health and safety data reporting at the start of the reporting period. 
The remaining reporting requirements, specifically categories 2(d), 
2(e), and 3, continue prospectively.
    Detailed guidance for reporting unpublished health and safety data 
is provided in the Federal Register of September 15, 1986 (51 FR 
32720). Also found there are explanations of the reporting exemptions.

C. Submission of PAIR Reports and Section 8(d) Studies

    PAIR reports and section 8(d) health and safety studies must be 
sent to: TSCA Document Processing Center (7407), Office of Pollution 
Prevention and Toxics, Environmental Protection Agency, 401 M St., SW., 
Washington, DC 20460, ATTN: (insert either PAIR or 8(d) Reporting).

D. Removal of Chemical Substances from the Rules

    Any person who believes that section 8(a) or 8(d) reporting 
required by this rule is unwarranted, should promptly submit to EPA in 
detail the reasons for that belief. EPA, in its discretion, may remove 
the substance from this rule for good cause (40 CFR 712.30 and 
716.105). When withdrawing a substance from the rule, EPA will issue a 
rule amendment for publication in the Federal Register.

IV. Economic Analysis

A. Preliminary Assessment Information Rule

    The economic analysis for the addition of the 28 chemicals to the 
TSCA Section 4(e) Priority List will be based largely on the methods 
and data sources developed for the analyses of the original Section 
8(a) Preliminary Assessment Information Rule (PAIR). These analyses 
are:
    1. Economic Impact and Small Business Definition Analysis for TSCA 
Section 8(a) Preliminary Assessment Information Rule. Office of 
Regulatory Analysis, OTS, U.S. EPA. February 1980.
    2. Economic Analysis of the Final Section 8(a) Preliminary 
Assessment Information Rule. R.A. Horner, Regulatory Impacts Branch, 
OTS, U.S. EPA. November 12, 1981.
    The Chemical Update System (CUS) was searched to determine the 
manufacturers and importers of the 28 chemicals. This search identified 
17 firms manufacturing or importing the 28 chemicals at a total of 14 
sites.
Reporting Costs (dollars)
(a) 26 reports estimated at $1,483.73 per report=$38,576.98
(b) 17 sites at $465.99 per site=$7,921.83
Total Cost=$46,498.81
Mean cost per site=$46,499/14 sites=$3,321.36
Mean cost per firm=$46,499/17 firms=$2,735.24
Reporting Burden (hours)
(a) Rule familiarization: 7 hrs/site x 14 sites=98
(b) Reporting: 22 hrs/report x 26 reports=572
Total burden hours=707
Average burden per site=707 hours/14 sites=50.5
Average burden per firm=707 hours/17 firms=41.6
EPA Costs (dollars)
    It is estimated that the annual cost to the Federal Government will 
be 1.36 FTEs (or 2,828.8 hours annually). At an estimated $69,370 per 
FTE, the total of 1.36 FTEs will cost EPA $94,343.

B. Health and Safety Data Reporting Rule

    EPA estimates the total reporting costs for establishing section 
8(d) reporting requirements for the 11 chemicals will be $84,954. The 
methodology used in this economic analysis was derived from the 
approach used in the analysis of the original 8(d) reporting: Impact 
Analysis for the Health and Safety Data Reporting Rule (Office of Toxic 
Substances, U.S. EPA, September 1982). Although EPA has used the best 
available data to make its economic projections, much of the 
information is based upon the 1986 TSCA Inventory Update and secondary 
information from industry sources.
    The estimated reporting costs are broken down as follows:

Initial corporate review.........................................$8,382
Site identification..............................................12,573
File searches at site............................................28,329
Photocopying existing studies.....................................3,208
Title listing.....................................................1,277
Managerial review for CBI........................................18,549
Reporting on newly-initiated studies................................491
Submissions after initial reporting period.......................11,653
Additional costs....................................................492
      Total......................................................84,954
Reporting Burden (hours)
(a) Initial review: 108 hrs
(b) Reporting: 953 hrs
Total reporting burden hours=1,061 hrs

V. Rulemaking Record

    The following documents constitute the record for this rule (docket 
control number OPPTS-82048). All of these documents are available to 
the public in the TSCA Nonconfidential Information Center (NCIC), 
formerly the TSCA Public Docket Office, from 12 noon to 4 p.m., Monday

VI. Regulatory Assessment Requirements

A. Executive Order 12866

    Pursuant to Executive Order 12866 (58 FR 51735, October 4, 1993), 
it has been determined that this rule is not ``significant'' because 
the Office of Management and Budget (OMB) has waived review of these 
types of actions, and is therefore not subject to OMB review.

B. Paperwork Reduction Act

    OMB has approved the information collection requirements contained 
in this rule under the provisions of the Paperwork Reduction Act of 
1980, 44 U.S.C. 3501 et seq. and has assigned OMB control number 2070-
0054 for PAIR reporting and 2070-0004 for TSCA section 8(d) reporting. 
Information concerning the collection of 

[[Page 7424]]
this information, its use, and estimated costs may be found in Units I. 
and IV. of this preamble.

C. Regulatory Flexibility Act

    Pursuant to the Regulatory Flexibility Act (5 U.S.C. 601 et seq.), 
the Agency must consider whether a regulatory action will have an 
adverse economic impact on small entities. Section 605(b) requires the 
Agency to either certify that the regulatory action will not have a 
significant economic impact on a substantial number of small entities, 
or prepare a regulatory flexibility analysis. EPA has determined that 
this regulatory action does not impose any adverse economic impacts on 
small entities.

D. Unfunded Mandates Reform Act and Executive Order 12875

    Pursuant to Title II of the Unfunded Mandates Reform Act of 1995 
(Pub. L. 104-4), EPA has determined that this regulatory action does 
not contain any ``unfunded mandates,'' as described by the Act, for 
State, local, or tribal governments or the private sector. In addition, 
EPA has determined that this action does not result in the expenditure 
of $100 million or more by any State, local or tribal governments, or 
by anyone in the private sector. The costs associated with this action 
are described in the Executive Order 12966 section above.

E. Executive Order 19898

    Due to the nature of this action which is confined to information-
gathering activities, it was not necessary for the Agency to consider 
environmental justice related issues pursuant to Executive Order 19898 
(59 FR 7629, February 16, 1994).
