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 32nd Report to 
EPA revised the Toxic Substances Control Act (TSCA) Section 4(e) 
Priority List by designating for testing 34 chemical substances. The 
ITC recommendations must be given priority consideration by EPA in 
promulgating test rules. EPA is adding certain of 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substances to report unpublished health and safety data to EPA.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 
document also makes certain modifications to a final rule published in 
the Federal Register of May 14, 1993, and a technical amendment to that 
rule published in the Federal Register of September 10, 1993.

Effective DATE: This rule will become effective on March 11, 1994.

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.

SUPPLEMENTARY INFORMATION: This rule adds 34 chemical substances to the 
PAIR and 28 chemical substances to 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chemicals will be required to report unpublished health and safety 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. Because the ITC has 
expressed no need for ecological effects information for the substances 
being added to the section 8(d) rule via this action, EPA is not 
requiring the reporting of these data for the subject substances under 
the section 8(d) rule.
    This rule also provides CAS Registry Numbers for seven chemicals 
listed under the siloxanes category in a final rule published in the 
Federal Register of May 14, 1993 (58 FR 28511). These CAS numbers did 
not exist at the time of publication of that rule, but they have since 
been assigned and are now included for both the PAIR and section 8(d) 
rule. The seven chemicals are: Octacosamethylcyclotetradecasiloxane 
(CAS No. 149050-40-8); dotriacontamethylcyclohexadecasiloxane (CAS No. 
150026-95-2); tetratriacontamethylcycloheptadecasiloxane (CAS No. 
150026-96-3); octatriacontamethylcyclononadecasiloxane (CAS No. 150026-
97-4); tetracontamethylcycloeicosasiloxane (CAS No. 150026-98-5); 
tetracontamethylnonadecasiloxane (CAS No. 150026-99-6); and 
dotetracontamethyleicosasiloxane (CAS No. 150027-00-2). Finally, in a 
technical amendment published in the Federal Register of September 10, 
1993 (58 FR 47647), the chemical polydimethylsiloxane (CAS No. 9016-00-
6), was inadvertently left in the regulatory text portion of 712.30(x); 
this document removes the chemical from 712.30(x).
    Additionally, this notice corrects two chemical names added to 40 
CFR parts 712 and 716 in the Federal Register of May 14, 1993. In 
712.30(x) and 716.120(d), non-endblocked siloxanes (CAS No. 70131-67-
8), is being revised to read siloxanes and silicones, di-Me, hydroxy-
terminated, and dimethylmethyl 3,3,3-trifluoropropyl (CAS No. 115361-
68-7), is being revised to read dimethylmethyl 3,3,3-trifluoropropyl 
siloxane.

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 June 2, 1993, EPA announced the receipt of the 32nd Report of 
the ITC, and it was then published in the Federal Register of July 16, 
1993 (58 FR 38490). The 32nd Report revises the Committee's priority 
list of chemicals by designating 34 chemical substances to the section 
4(e) priority list.
    At the request of the Occupational Safety and Health Agency (OSHA), 
the ITC designated, via its 32nd Report, a group of 34 chemical 
substances which may cause harm to exposed workers by absorption 
through the skin. OSHA nominated these substances (and 24 previously 
via the ITC's 31st Report (58 FR 26898, May 5, 1993)) for testing to 
support the assignment of Permissible Exposure Limits (PELS) ``skin 
designations.''
    This rule adds 34 chemical substances to the PAIR and 28 substances 
to the section 8(d) Health and Safety Data Reporting Rule (6 substances 
are currently listed on the 8(d) rule, as described in Unit II of this 
preamble). These two rules are model information gathering rules which 
assist 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.
    For the chemicals listed under Sec. 716.120(d) of the section 8(d) 
rule which are being added under the category ``OSHA Chemicals in Need 
of Dermal Absorption Testing,'' the reporting of ecological effects 
data will not be required. Because no member of the ITC has expressed a 
need for these data, EPA believes there is no need to collect this 
information at this time.

II. Chemicals To Be Added

    In its 32nd Report to EPA, the ITC designated 34 chemical 
substances for dermal absorption testing. EPA is adding 34 chemical 
substances to the PAIR and 28 substances to the section 8(d) Health and 
Safety Data Reporting Rule; these substances are listed in the 
regulatory text section of this document. EPA is not adding to the 
section 8(d) six of the substances listed in the ITC report because the 
substances were previously listed on the section 8(d) rule and are 
currently subject to reporting. These six substances are: Bromoform 
(CAS No. 75-25-2), (52 FR 16022, May 1, 1987); 1,1-dichloroethane (CAS 
No. 75-34-3), (52 FR 16022, May 1, 1987); methyl methacrylate (CAS No. 
80-62-6), (54 FR 8484, February 28, 1989); p-toluidine (CAS No. 106-49-
0), (51 FR 2890, January 22, 1986); beta-chloroprene (CAS No. 126-99-
8), (49 FR 46741, November 28, 1984); and m-phthalodinitrile (CAS No. 
626-17-5), (56 FR 42688, August 30, 1991).
    Manufacturers, importers, and processors of the 28 substances being 
listed on the 8(d) rule by this action will not be required to report 
ecological effects data under the 8(d) rule for those substances.
    For a complete listing of the substances being added to the section 
8(d) rule and the PAIR, see the regulatory text section of this 
document.

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 10, 1994. 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.
    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. Release of Aggregate Data

    EPA will follow procedures for the release of aggregate statistics 
as prescribed in the Federal Register notice of June 13, 1983 (48 FR 
27041). Included in the notice are procedures for requesting exemptions 
from the release of aggregate data. Exemption requests concerning the 
release of aggregate data on any chemical substance must be received by 
EPA no later than May 10, 1994.

V. Economic Analysis

A. Preliminary Assessment Information Rule

    EPA estimates the PAIR reporting cost of this rule is $258,405. To 
calculate this figure, EPA used information from a variety of published 
sources as well as information from OPPTS's Risk Management 1 (RM1) 
reports on similar chemicals to generate a list of 107 firms that 
manufacture and/or import the 34 chemicals at a total of 161 sites. The 
published sources used include: SRI International's Directory of 
Chemical Producers, Chemical Economics Handbook, and Specialty 
Chemicals; other multi-client studies; the U.S. International Trade 
Commission's Synthetic Organic Chemicals; and company product 
literature. An unknown number of the businesses affected by the 
addition of the chemicals to the Priority List may qualify as a small 
business as defined in 40 CFR 712.25(c). However, for this analysis it 
is assumed that all firms identified will report. Therefore, EPA 
expects 107 firms to generate a total of 161 reports (some sites 
produce more than 1 of the 34 chemicals).
                    Reporting Costs (dollars)
(a) 161 reports estimated at $843 per report = $135,723
(b) 234 sites at $762 per site = $122,682
Total Cost = $258,405
Mean cost per site = $258,405/161 sites = $1,605
Mean cost per firm = $258,405/107 firms = $2,415
                    Reporting Burden (hours)
(a) Rule familiarization: 18 hrs/site x 161 sites = 2,898
(b) Reporting: 16 hrs/report x 161 reports = 2,576
Total burden hours = 5,474
Average burden per site = 5,474 hours/161 sites = 34
Average burden per firm = 5,474 hours/107 firms = 51
                    EPA Costs (dollars)
Processing cost = 161 reports x $95/report = $15,295

B. Health and Safety Data Reporting Rule

    EPA estimates the total reporting costs for establishing section 
8(d) reporting requirements for 28 chemicals will be $111,939. This 
cost estimate is high because the Agency is uncertain about the likely 
number of respondents to the rule. 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. Therefore, EPA tends to overestimate 
rather than underestimate reporting burden.
    The estimated reporting costs are broken down as follows: 

Initial corporate review                                        $ 26,811
Site identification                                               13,250
File searches at site                                             27,242
Photocopying existing studies                                      4,585
Title listing                                                      1,380
Managerial review for CBI                                         26,707
Reporting on newly-initiated studies                                 580
Submission of newly-initiated studies                              1,035
Submissions after initial reporting period                        10,349
                                                ------------------------
                                                                        
Total                                                         $ 111,939 
------------------------------------------------------------------------

                Reporting Burden (hours)
(a) Initial review: 2 hours/firm x 258 firms = 516 hrs
(b) Reporting: 6.2 hours/firm x 258 firms = 2,174 hrs
Total reporting burden hours = 2,690 hrs

VI. Rulemaking Record

    The following documents constitute the record for this rule (docket 
control number OPPTS-82042). 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 
through Friday, excluding legal holidays. The NCIC is located at EPA 
Headquarters, Rm. E-G102, 401 M St., SW., Washington, DC 20460.

VII. Regulatory Assessment Requirements

A. Executive Order 12866

    Under Executive Order l2866 (58 FR 51735, October 4, 1993), the 
Agency must determine whether the regulatory action is ``significant'' 
and therefore subject to review by the Office of Management and Budget 
(OMB) and the requirements of the Executive Order. Under section 3(f), 
the order defines a``significant regulatory action'' as an action that 
is likely to result in a rule (1) having an annual effect on the 
economy of $100 million or more, or adversely and materially affecting 
a sector of the economy, productivity, competition, jobs, the 
environment, public health or safety, or State, local or tribal 
governments of communities (also referred to as ``economically 
significant''); (2) creating serious inconsistency or otherwise 
interfering with an action taken or planned by another agency; (3) 
materially altering the budgetary impacts of entitlement, grants, user 
fees, or loan programs or the rights and obligations of recipients 
thereof; or (4) raising novel legal or policy issues arising out of 
legal mandates, the President's priorities, or the principles set forth 
in this Executive Order.
    Pursuant to the terms of this Executive Order, it has been 
determined that this rule is not ``significant'' and is therefore not 
subject to OMB review.

B. Paperwork Reduction Act

    The information collection requirements contained in this rule have 
been approved by OMB under the provisions of the Paperwork Reduction 
Act of 1980, 44 U.S.C. 3501 et seq. and have been assigned OMB control 
numbers 2070-0054 for PAIR reporting and 2070-0004 for TSCA section 
8(d) reporting.
    Public reporting burden for this collection of information is 
estimated to average 34 hours for PAIR per response and 8.2 hours for 
section 8(d), including time for reviewing instructions, searching 
existing data sources, gathering and maintaining the data needed, and 
completing and reviewing the collection of information.
    Send comments regarding the burden estimate or any other aspect of 
this collection of information, including suggestions for reducing this 
burden, to Chief, Information Policy Branch, 2131, U.S. Environmental 
Protection Agency, 401 M St., SW., Washington, DC 20460; and to the 
Office of Information and Regulatory Affairs, Office of Management and 
Budget, Washington, DC 20503, marked ``Attention: Desk Officer for 
EPA.''
