 Preface

	This findings document was prepared to support EPA’s Proposed TSCA
Section 4 Test Rule for Certain High Production Volume Chemicals; Third
Group of Chemicals.  Prior to promulgating a test rule under section 4
of the Toxic Substances Control Act (TSCA), 15 U.S.C. §§2601 et seq,
EPA is required to make certain findings identified in section 4(a) of
TSCA relating to the chemical’s risk and potential exposure, the
sufficiency of data to allow EPA to determine the human health or
environmental effects of the chemical, and the need to conduct testing.

 

	Under TSCA section 4(a)(1)(B), EPA must make the following findings to
support a test rule based on concerns for exposure: (1) that a chemical
substance is or will be produced in substantial quantities and that it
enters or may reasonably be anticipated to enter the environment in
substantial quantities and/or that there is or may be substantial and/or
significant human exposure to such substance; (2) that there are
insufficient data and experience upon which the effects of the
manufacture, distribution in commerce, processing, use or disposal of
such substance or mixture or of any combination of such activities on
health or the environment can reasonably be determined or predicted; and
(3) that testing of the substance or mixture with respect to such
effects is necessary to develop such data.  The criteria and standards
used by EPA for evaluating the terms “substantial production,”
“substantial release,” and “substantial or significant human
exposure” as used in TSCA section 4(a)(1)(B)(i) are explained in
EPA’s Final Statement of Policy; Criteria for Evaluating Substantial
Production, Substantial Release, and Substantial or Significant Human
Exposure set forth at 58 FR 28736 (May 14, 1993) (hereinafter referred
to as the “B Policy”).

	This document provides a detailed discussion of EPA’s evaluation of
each of the chemical substances identified in the proposed test rule to
determine that preliminary TSCA section 4(a)(1)(B) findings concerning
“substantial production,” “substantial release,” and
“substantial or significant human exposure” can be made. Data
Source Descriptions

TSCA Inventory Update Reporting Rule: In 1986, EPA promulgated the
Inventory Update Reporting (IUR) regulations, under TSCA section 8(a),
to facilitate the periodic updating of the TSCA Inventory database and
to otherwise support activities associated with implementing TSCA. As
originally promulgated, the IUR required chemical manufacturers
(including importers) to report to EPA every 4 years the identity of
chemical substances manufactured (including imported) annually in
quantities of 10,000 pounds or more at each plant site they owned or
controlled. In 2003 EPA adjusted the universe of chemicals and plant
sites that are required to report, and the type of information reported.
In 2005, EPA changed the reporting frequency to once every 5 years,
revised the manner in which amounts of a chemical substance manufactured
or imported must be reported, and changed the submission period for
reporting after 2006.

To protect the claims of confidential business information (CBI)
asserted by some IUR submitters on the amount of the chemical substance
manufactured (including imported) at a specific site, all production
volumes reported by IUR submitters (i.e., CBI and non-CBI) for each
chemical are combined by EPA for an aggregate total.  Confidential
business information claims are further protected by using eight ranges
to identify the total for any specific chemical and then making
available to the public the range that corresponds to the aggregate
production volume. Publicly-available information from the 1986, 1990,
1994, 1998, and 2002 (and 2006) IUR reporting cycles are available
on-line at:   HYPERLINK http://www.epa.gov/oppt/iur/index.htm
http://www.epa.gov/oppt/iur/index.htm 

The Toxics Release Inventory (TRI) contains information about releases
of certain chemicals and management of wastes at a wide variety of
sources, including manufacturing operations, certain service businesses,
and federal facilities.  Publicly-available information from the 2005
TRI reporting cycle is available on-line at:   HYPERLINK
http://www.epa.gov/triexplorer/ http://www.epa.gov/triexplorer/ 

The National Institute for Occupational Safety and Health (NIOSH)
conducted the National Occupational Exposure Survey (NOES) that
collected data on potential occupational exposures to chemical,
physical, and biological agents from 1981 to 1983.  The survey involved
on-site visits to 4,490 establishments in 522 industry types employing
approximately 1,800,000 workers in 377 occupational categories. 
Publicly-available information from the NOES is available on-line at:  
HYPERLINK http://www.cdc.gov/noes/default.html
http://www.cdc.gov/noes/default.html 

The National Library of Medicine Household Products Database provides
information on the chemical ingredients and their percentage in specific
brands of household products.  Information in the database is from a
variety of publicly available sources including brand-specific labels
and Material Safety Data Sheets when available from manufacturers and
manufacturers' web sites.  Publicly-available information from the
database is available on-line at:   HYPERLINK

commercial/consumer product category (C20)

65996-82-9	Tar oils, coal	The IUR commercial/consumer product categories
C16-Rubber and plastic products, C19-Wood and wood furniture, and
C20-Other (chemicals contained in commercial and consumer products not
elsewhere classified) were reported for this chemical. Chemicals
reporting in these product categories are contained in tires, footwear,
flooring, bottles, sporting equipment, games, toys, wood products and
wood furniture, along with an unknown number of commercial and consumer
products that may potentially have a high number of exposures.  It is
expected that these products will be widely used by commercial workers
and consumers and hence, may likely exceed 1,000 commercial workers and
10,000 consumers.  Based on this information, this chemical would meet
the exposure based findings criteria of "substantial or significant
human exposure.”  (All stated IUR  commercial/consumer product
categories are non-CBI)

This chemical met exposure based findings criteria based on:

- 2006 IUR Production Volume Range (100 million - 1 billion lb)

- Total workers potentially exceeding 1,000 based on IUR
commercial/consumer product categories (C16, C19, C20)

- Consumers potentially exceeding 10,000 people based on IUR
commercial/consumer product category (C16,C19,C20)

65996-89-6	Tar, coal, high-temp.	The total number of potentially exposed
workers is likely to exceed 1,000 based on reported PAIR data. 
Additionally, the number of potentially exposed consumers is estimated
to be very large based on the reported IUR commercial/consumer product
categories for this chemical: C12-Paints and coatings, and C20-Other
(chemicals contained in commercial and consumer products not elsewhere
classified). Chemicals reporting in these product categories are
commercial and consumer paints (paste or ready-mix) including artists’
paints, varnishes, lacquers, enamels and shellac, paint and varnish
removers and cleaners, along with an unknown number of commercial and
consumer products that may potentially have a high number of exposures. 
It is expected that these products will be widely used by commercial
workers and consumers and hence, may likely exceed 1,000 commercial
workers and 10,000 consumers.  PAIR indicates >1 million lbs of this
chemical is released to the environment.  Based on this information,
this chemical would meet the exposure based findings criteria of
"substantial or significant human exposure" and “significant or
substantial release.”  (All stated IUR  commercial/consumer product
categories are non-CBI)

This chemical met exposure based findings criteria based on:

- 2006 IUR Production Volume Range (> 1 billion lb)
