Forty-Fourth Report of the TSCA Interagency Testing Committee to
the Administrator; Receipt of Report and Request for Comments

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

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

SUMMARY: The Toxic Substances Control Act (TSCA) Interagency Testing
Committee (ITC) transmitted its Forty-Fourth Report to the
Administrator of the EPA on May 27, 1999. In the 44\th\ Report, which
is included with this notice, the ITC initiated a process to identify
chemicals with production volumes greater than 10,000 pounds per year
that are predicted to bioconcentrate, persist, and cause ecological or
human health effects. To date the process has identified more than 400
chemicals.
At this time, the ITC is implementing the process and has no
revisions to its TSCA section 4(e) Priority Testing List. EPA invites
interested persons to submit written comments on the Report.

DATES: Comments, identified by docket control number OPPTS-41052, must
be received on or before December 15, 2000.

ADDRESSES: Comments may be submitted by mail, electronically, or in
person. Please follow the detailed instructions for each method as
provided in Unit I. of the SUPPLEMENTARY INFORMATION. To ensure proper
receipt by EPA, it is imperative that you identify docket control
number OPPTS-41052 in the subject line on the first page of your
response.

II. Background

The Toxic Substances Control Act (TSCA) (15 U.S.C. 260l et seq.)
authorizes the Administrator of the EPA to promulgate regulations under
section 4(a) requiring testing of chemicals and chemical groups in
order to develop data relevant to determining the risks that such
chemicals and chemical groups may present to health or the environment.
Section 4(e) of TSCA established the ITC to recommend chemicals and
chemical groups to the Administrator of the EPA for priority testing
consideration. Section 4(e) of TSCA directs the ITC to revise the TSCA
section 4(e) Priority Testing List at least every 6 months.

A. The ITC's 44\th\ Report

The 44\th\ Report was received by the EPA Administrator on May 27,
1999, and is included in this notice. In the 44\th\ Report, the ITC
stated that it had initiated a process to identify chemicals with
production/importation volumes greater than 10,000 pounds per year that
are predicted to bioconcentrate, persist, and cause ecological or human
health effects. According to the ITC report, more than 400 chemicals
have been identified.

B. Status of the Priority Testing List

At this time, the ITC is implementing the process and has no
revisions to its TSCA section 4(e) Priority Testing List. The current
TSCA section 4(e) Priority Testing List as of May 1999 can be found in
Table 1 of the 44\th\ ITC Report which is included in this notice.

Forty-Fourth Report of the TSCA Interagency Testing Committee to the
Administrator, U.S. Environmental Protection Agency

This is the 44th Report of the TSCA Interagency
Testing Committee (ITC) to the Administrator of the U.S.
Environmental Protection Agency (EPA). The ITC was established by
section 4(e) of the Toxic Substances Control Act (TSCA) ``to make
recommendations to the Administrator respecting the chemical
substances and mixtures to which the Administrator should give
priority consideration for the promulgation of a rule for testing
under section 4(a).... At least every six months..., the Committee
shall make such revisions to the Priority Testing List as it
determines to be necessary and transmit them to the Administrator
together with the Committee's reasons for the revisions'' (Public
Law 94-469, 90 Stat. 2003 et seq. (15 U.S.C. 2601 et seq.)). Since
its creation in 1976, the ITC has submitted 43 semi-annual (May and
November) Reports to the EPA Administrator transmitting the Priority
Testing List and its revisions. In 1989, the ITC began recommending
chemical substances for information reporting, screening, and
testing to meet the data needs of its member U.S. Government
organizations. ITC Reports are available from http://www.epa.gov/
opptintr/itc within a few days of submission to the Administrator
and from http://www.epa.gov/fedrgstr after publication in the
Federal Register. The ITC meets monthly and produces its revisions
to the Priority Testing List with administrative and technical
support from the ITC staff and contract support provided by EPA. ITC
members and staff are listed at the end of this Report.
During this reporting period (November 1998 to May 1999), the
ITC began developing a process to identify chemicals with production
or importation volumes >10,000 lb/year that are predicted to
bioconcentrate, persist, and cause ecological or human health
effects. To date, the process has been used to identify more than
400 chemicals with production or importation volumes >10,000 lb/year
with log octanol-water partition coefficients and aerobic
biodegradation removal rates that suggest bioconcentration and
persistence potential. In addition, the process is being used to:
1. Organize chemicals into structurally related chemical classes
for the purpose of developing structure activity relationships
(SARs).
2. Characterize the type, quantity, and quality of ecological or
human health effects data associated with each chemical.
3. Determine uses.
4. Estimate potential environmental releases and human
exposures.
5. Evaluate existing regulations.
6. Identify U.S. Government data needs.
This process supports EPA's current High Production Volume (HPV)
Chemical Challenge program (http://www.epa.gov/opptintr/chemrtk/
volchall.htm) and Persistent Bioaccumulative Toxics (PBT) project
(http://www.epa.gov/opptintr/chemrtk/persbioa.htm). At this time,
the ITC is implementing this process and has no revisions to its
TSCA section 4(e) Priority Testing List which follows as Table 1.
