Technical Workshop on the Potential

for Application of 2,3,7,8–TCDD

Toxicity Equivalency Factors to

Aquatic Life and Wildlife

AGENCY: Environmental Protection

Agency (EPA).

ACTION: Notice of meeting.

SUMMARY: EPA is announcing a

workshop to evaluate the application of

toxicity equivalency factors (TEFs) for

2,3,7,8–TCDD to the assessment of risks

from polychlorinated dioxins, furans,

and biphenyls to terrestrial and aquatic

wildlife. The workshop will be open to

members of the public as observers. The

application of TEFs, which are based on

different experimental systems and

varying amounts of empirical data, will

be studied in the context of

representative case studies.

DATES: The workshop will begin on

Tuesday, January 20, 1998, at 3 p.m. and

end on Thursday, January 22, 1998, at

5 p.m. Members of the public may

attend as observers.

ADDRESSES: The meeting will be held at

the Chicago Hilton and Towers, 720 S.

Michigan Ave., Chicago, IL 60605,

Telephone (312) 922–4400.

FOR FURTHER INFORMATION CONTACT: For

technical inquiries, contact Cynthia

Nolt, U.S. EPA Office of Science Policy

(8104R), 401 M Street SW, Washington,

DC 20460, Telephone (202) 564–6763.

Eastern Research Group, Inc., an EPA

contractor, is convening this workshop.

To attend the workshop as an observer,

contact Eastern Research Group, Inc.,

Telephone (781) 674–7374.

SUPPLEMENTARY INFORMATION: The

purpose of the workshop is to explore

the application of additivity models for

polychlorinated dioxins, furans, and

biphenyls in problem formulations and

effects characterizations of ecological

risk assessments for aquatic life and

avian and mammalian wildlife. In two

previous workshops, convened by the

World Health Organization in August

1996 and June 1997, scientific experts

reached consensus on a scheme for

prioritizing data sets and TEFs for

aquatic life and wildlife. This third

workshop will examine the use of a TEF

approach in effects characterization in

prospective risk assessments, as well as

in retrospective risk assessments, where

it may be applied as a diagnostic tool to

assess relative risk.

The workshop will consist of three

panels that are to address uncertainties,

such as lack of knowledge and

variability, associated with WHO

consensus TEFs (and the data sets for

aquatic, avian, and mammalian wildlife

from which the TEFs were determined),

in the context of two risk assessment

case studies. The prospective case study

involves a risk assessment for a

hypothetical point source requiring a

water quality permit with standards that

will protect aquatic life and wildlife at

the individual and population levels of

biological organization. The

retrospective case study focuses on a

hypothetical freshwater ecosystem in

which scientists have observed

reproductive effects and have measured

exposures in both biota and sediments.

The panels will relate the exposure

levels to a concentration of concern and

a threshold for remediation.

To focus the workshop, the

deliberations will address only

compounds whose mode of action is

elicited through the arylhydrocarbon

receptor (AhR). The workshop will not

address either chemicals with different

modes of action or nonchemical

stressors. In addition, the workshop

deliberations will be restricted to the

direct effects of AhR agonists, and will
