1. Integrated Risk Project Steering Committee
The Integrated Risk Project (IRP) Steering Committee, an ad hoc
committee established by the Executive Committee of the Science
Advisory Board, will meet on July 16-17, 1996, at the Morrison House,
116 South Alfred Street, Alexandria, VA 22314, telephone (703) 838-
8000. The meeting will begin at 8:30 a.m. on July 16, and at 8:00 a.m.
on July 17, and end no later than 5:30 p.m. on both days. Seating will
be limited and available on a first-come, first-served basis. The
purpose of the meeting is to receive reports from the Subcommittees of
the IRP and to begin discussion of an integrated model for decision-
making that incorporates information on risks to ecosystems and humans,
risk reduction options, and their economic implications.
Background on the Integrated Risk Project
In a letter dated October 25, 1995, to Dr. Matanoski, Chair of the
SAB Executive Committee, Deputy Administrator Fred Hansen charged the
SAB to: (a) develop an updated ranking of the relative risk of
different environmental problems based upon explicit scientific
criteria; (b) provide an assessment of techniques and criteria that
could be used to discriminate among emerging environmental risks and
identify those that merit serious, near-term Agency attention; (c)
assess the potential for risk reduction and propose alternative
technical risk reduction strategies for the environmental problems
identified; and (d) identify the uncertainties and data quality issues
associated with the relative rankings. The project will be conducted by
several SAB panels, working at the direction of an ad hoc Steering
Committee established by the Executive Committee.
Single copies of Reducing Risk, the report of the previous relative
risk ranking effort of the SAB, can be obtained by contacting the SAB's
Committee Evaluation and Support Staff (1400), 401 M Street, SW,
Washington, DC 20460, telephone (202) 260-8414, or fax (202) 260-1889.

2. Ecological Processes and Effects Committee
The Ecological Processes and Effects Committee (EPEC) of the
Science Advisory Board (SAB) will meet on July 18-19, 1996, at the
Environmental Protection Agency's Washington Information Center (WIC),
Conference Room 17, 401 M Street, SW, Washington, DC 20460. The meeting
will begin at 8:30 a.m. on July 18 and at 8:00 a.m. on July 19, and end
no later than 5:00 p.m. on each day.
The main purpose of the meeting is to: a) review the planning and
problem formulation for several watershed-level ecological risk
assessment case studies; b) discuss a process for identifying and
ranking ecological risks as part of the SAB's Integrated Risk Project;
and c) discuss EPEC Subcommittee reports, possibly including reports
from the Marsh Management Subcommittee and the Lakes Biocriteria
Subcommittee.
Background on the Watershed-Level Ecological Risk Assessment Case
Studies
The Office of Water and the Office of Research and Development have
asked the Committee to conduct a two-stage review of the five case
studies being prepared to illustrate ecological risk assessment for
watersheds experiencing multiple stressors. In 1993, watershed teams
began the development of risk assessments for five watersheds: Big
Darby Creek, OH; Clinch River, VA; Middle Platt River Wetlands, NE;
Snake River, ID; and Waquoit Bay Estuary, MA. The initial review
(termed an SAB Advisory) will focus on the approach to planning and
problem formulation, illustrated primarily by the draft case study for
Waquoit Bay, with additional examples being drawn from the other case
studies where appropriate. The Charge to the Committee is to evaluate
the process for: framing the risk assessment to respond to management
goals; selecting relevant assessment endpoints and measures; developing
conceptual models that represent the interactions among multiple
stressors, exposure pathways, ecological effects, and ecosystem
processes; and developing an analysis plan.
Single copies of the materials supplied to the Committee, including
the draft case studies, can be obtained by contacting Ms. Crystal
Robinson, EPA Risk Assessment Forum (W635), 401 M Street, SW,
Washington, DC 20460, telephone (202) 260-6743.

3. Environmental Health Committee
The Environmental Health Committee (EHC) of the Science Advisory
Board (SAB) will meet on July 18-19, 1996 at the Holiday Inn
Georgetown, 2101 Wisconsin Avenue NW, Washington D.C. 20007, telephone
(202) 338-4600. The meeting will start at 9:00 a.m. and end no later
that 5:00 p.m. (Eastern Daylight Time) each day. Due to limited space,
seating at the meeting will be on a first-come basis. The main purpose
of the meeting is to discuss and review two documents: the EPA's
Proposed Guidelines for Neurotoxicity Risk Assessment and the revised
Thyroid Cancer Risk Assessment Policy Document.
Background on the Reviews
The Committee's review of the Neurotoxicity Risk Assessment
Guidelines will include the following issues: (a) combining hazard
identification and dose-response evaluation to reflect more accurately
the process used for noncancer health; (b) compensation and recovery of
function in neurotoxicological studies and how to account for
compensation in neurotoxicology risk assessment; (c) the use of blood
and/or brain acetylcholinesterase activity as an indication of
neurotoxicity for risk assessment; (d) endpoints indicative of
neurotoxicity that may not be covered by these proposed Guidelines,
e.g., endocrine disruption or neuroendocrine-mediated neurotoxicity;
(e) the completeness of the description of the endpoints used in human
and animal neurotoxicological assessments; (f). the possibility of no
threshold for some neurotoxic agents; (g) the treatment of susceptible
populations and individuals by the proposed Guidelines; and (h) the use
of the Benchmark Dose in Neurotoxicity Risk Assessment.
The review of the Thyroid Cancer Risk Assessment Policy Document
will include the following issues: (a) the relevant science and its
support of the proposed science policy position; (b) the summary of the
state of knowledge regarding potential susceptibility for thyroid
cancer development and the proposed science policy position; (c) the
reasonableness of the science policy position that disruption in
thyroid-pituitary status may be associated with increases in thyroid
cancer risk; (d) the seven factors for assessing whether or not a
chemical has antithyroid activity and the minimal criteria for making
such a determination; (e) the proposed default assumption that the
significance of human exposure to antithyroid carcinogens should be
evaluated by margin-of-exposure considerations unless biologically
based models and data are available; and (f) the nature, adequacy and
completeness of the provided case studies and of the guidance for using
the information.

Guidelines may have on the assessment of waterborne cancer hazards;
and, e) finish drafting the DWC's report on the Agency's Five Year
Research Plan for Microbes and Disinfectant By-Products.
Background on the Statistical Evaluation of Pathogenic Parasites
The Agency has conducted an Information Collection Rule (ICR) which
among other things provided data about the occurrence of the pathogenic
parasites Cryptosporidium and Giardia in several hundred water
supplies. Information about pathogen occurrence and the treatment
options is needed for a Regulatory Impact Analysis of the
[[Page 32798]]
Enhanced Surface Water Treatment Rule (ESWTR). While the Office of
Water (OW) does not believe that current statistical methods are
appropriate for evaluating occurrence and treatment efficacy at
individual sites, it does think it has developed an appropriate
approach for conducting a National Impact Analysis. The charge to the
Committee is to evaluate: (a) the factual and conceptual soundness of
the approach and methods used, and the soundness of the results and
conclusions of the report; (b) the suitability of the assumptions and
conditions tested in the report; (c) the suitability of the report as a
basis for making a decision on the use of protozoan monitoring data for
a national impact assessment; and, (d) whether the degree of accuracy
and precision of the protozoan method is acceptable for an impact
analysis.
For Further Information--Single copies of the Statistical Methods
can be obtained by contacting Mr. John Fox, Office of Water (4304), US
EPA, 401 M Street, SW, Washington, DC 20460, telephone (202) 260-9889
