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.

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 44th Report

The 44th Report was received by the EPA Administrator on May 27, 1999, and is included in this notice. In the 44th 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 44th 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.
