Science Advisory Board Creates Modeling
Study Qroup
by Kathleen Conway (FTS 382-2552)
The Science Advisory Board (SAB) has formed a
Modeling Study Group to look into the Agency's
implementation of its Resolution on Use of Mathematical
Models by EPA for Regulatory Assessment and
Decision-making and related issues. The SAB is a group
of non-government scientists and engineers who advise
the Administrator and Congress on how EPA conducts
and uses science. Its meetings and reports are public.
Single copies of the Resolution are available free of
charge by calling FTS 382-2552 and requesting Report
Number EPA-SAB-EEC-89-012.
The Resolution makes recommendations critical to
improving the use of models by EPA. These issues
include:
•	the use of state-of-the-art models
•	needs for
-	a better balance between data collection and
modeling,
model confirmation and sensitivity/uncertainty
analysis,
-	a central coordinating group to provide
oversight and guidance on model use within the
Agency,
-	more scientists and engineers with modeling
skills,
review of new modeling technologies, and
-	peer review of model development and
application.
The Resolution was prepared by the SAB's
Environmental Engineering Committee, which has
considerable experience in ground- and surface-water
models and has recently reviewed a number of models
relating to the land disposal of wastes.

Regional Operations Staff - ORD Facilitator
by David S. Klauder (FTS 382-7667)
This article is the first in a series to describe the risk-
related activities of the Regional Operations Staff (ROS),
in the Office of Regulatory Support and Technology
Transfer (OTTRS), ORD. Subsequent Risk Assessment
Review articles will profile ROS risk-related activities on
a region-by-region basis.
The principal function of the ROS is to .work with
regional staff to identify research and technical
assistance needs in regional program offices and to
facilitate resolution of these needs within ORD. A major
component of the ROS program to address this
objective is the Regional Scientist Program (RSP). .The
goal of the RSP is to locate one ORD scientist or
engineer in each region on a one- to two-year detail to
serve as an on-site liaison between ORD and the region.
The Regional Scientist is to work directly with senior
regional management and staff to resolve high priority
scientific issues of concern to the region using ORD
expertise and resources.
Currently, Norm Kulujian from CERI/OTTRS/ORD is in
the Environmental Services Division (ESD), Region 3;
Dick Moraski from OHEA/ORD is in ESD, Region 8; and
Spencer Peterson from the ORD Corvallis Laboratory is
in ESD, Region 10. An additional five ORD
scientists/engineers are being located in Regions 1, 4, 5,
6, and 7 this summer. Each Regional Scientist will bring
individual scientific and technical expertise which may
be applied to problems within each region. Each
scientist or engineer has resources, contracts, and
information to accomplish the objective of getting the
regional high priority research and technical assistance
needs addressed. I encourage regional staff to get to
know its Regional Scientist.
ROS also prepares a monthly report, the "ORD Regional
Highlights," which is circulated to the RA, DRA, and all
Division Directors within each region. This is a one- to
three-page region-specific report of ORD activities
ongoing or planned in the region. The report is divided
into three sections. The first contains a listing of all ORD
grants and cooperative agreements awarded to
government and academic institutions in the region. The
second contains a list of all ORD-sponsored workshops
and conferences in the region. The third contains short
abstracts and ORD contacts for ORD research and
technical assistance projects ongoing in the region.
Division directors have copies of "ORD Regional
Highlights."

SAB (Continued from p. 1)
The newly-formed six-member Modeling Study Group
has expertise in other modeling areas as well. For the
April 6 - 7, 1989, public meeting, each member
prepared a brief paper on the state of the art of
environmental modeling in his or her field.
Presentation of these papers, discussion of the tasks the
study group should undertake, and presentations by
Agency staff made up the bulk of the meeting. There
was considerable discussion over whether to begin the
study group's work by assessing the state of the art of
environmental modeling generally, followed by an
assessment of the state of the art of modeling at EPA, or
to begin the work with tasks of more immediate utility to
the Agency. The majority of the study group and
attendees favored the latter approach.
The study group's first major task will be the
development of a unified protocol for the development,
validation, and release of models for public use. The
protocol will address:
1.	Identification of problems/issues,
2.	Proper level of complexity and aggregation (possi-
bly including model structure and components,
assumptions and defaults),
3.	Time and space scales,
4.	Sensitivity and uncertainty analyses, and
5.	Peer review.
The study group believes two tasks must be undertaken
first to support the unified protocol development:
1.	Identification of terms and drafting of definitions.
Each member will identify terms for which
definitions would be important (or perhaps only
helpful). Members will each attempt to define the
following terms: model, protocol, calibration,
verification, validation, sensitivity, uncertainty, and
complexity. The Agency is invited to make the
study group aware of definitions it uses and any
Agency efforts currently underway to define terms. I
will be consolidating the terms and definitions which
are sent to me by putting one term on each sheet
of paper, followed by the various definitions.
2.	Generic comments by media on structure and
components of models.
Each member will write a brief (perhaps ten-page)
paper on structure and components of models in his
or her area of expertise. These papers will also
address typical assumptions and defaults. The
Agency is invited to comment on these issues. I
would appreciate receiving submission of these
papers as soon as possible so that they can be
circulated to the study group.
The study group will hold a conference call on Tuesday,
July 11, from 1:30 - 3:30 p.m. (EDT) to discuss the
definitions and generic structure papers and to prepare
for the next task identified by the study group - the
development of a unified protocol for the development,
validation, and release of models for public use.
Besides the three tasks above (definitions, structure
paper, and unified protocol) which will be addressed this
summer, the study group is also concerned with:
1.	The historical development of models in the
Agency, including their legislative mandates and the
original intent of the models,
2.	Calibration, verification, and validation procedures,
and
3.	Establishment of criteria to determine the
applicability or utility of models. ,
For further information on the study group or to submit
materials for consideration, please contact Kathleen
Conway at FTS 382-2552.
ROS (Continued from p.1)
Lastly, ROS has several cooperative agreements with
associations representing state and local governments to
identify and respond to research and technical
assistance needs at these levels of government.
Currently, we have cooperative agreements with the
National Governors' Association, the Association of State
and Territorial Health Officials, and Public Technology,
Incorporated, the nonprofit research and technology arm
of the National League of Cities and the International
City Management Association. Any one of these
mechanisms could be made available to the regions for
projects appropriately addressed by these associations.
The next article, on ROS activities in Region 3, will be
presented in the Risk Assessment Review by Norm
Kulujian.
II. Headquarters
IRIS Service Codes Aid Chemical Research
Jacqueline Patterson (FTS 684-7574)
The Integrated Risk Information System (IRIS) includes
several features that are not known to many users.
Service Code 3 of IRIS contains revision history
information that is useful for determining what has
changed in a chemical file since it was loaded. Service
Code 8 contains a list of the chemicals that the
Reference Dose (RfD) and Carcinogen Risk Assessment
Verification Endeavor (CRAVE) Work Groups will be
reviewing in the next six months.
The revision history provides a brief explanation of each
change made to an IRIS file. The date of the change is
given, along with the section affected and the
explanation. For example, for the chemical file Isoxaben
the IRIS revision history looks like this:
Isoxaben; CASRN 82558-50-7

-------
To view a chemical's revision history, one simply uses
the same search and read sequence as with Service
Code 1; however, since there is only one entry for each
chemical, the user does not need to scan the titles. No
entry for a chemical means that no changes have been
made to the IRIS file since its loading on the system. In
addition to reviewing Service Code 3, users should be
aware that the date of last revision for each section is
listed in the table at the beginning of each chemical file.
Service Code 8 is the newest feature of IRIS and was
added to the system last year. This service code
provides a list of chemicals that will be reviewed by the
RfD and CRAVE Work Groups. Users can refer to this
list if the chemical of interest is not found in Service
Code 1. Some of these chemicals are currently under
review by one or both work groups, others are planned
for review. For more information on the status of a
particular chemical's review, contact IRIS User Support
at FTS 684-7254.
Risk Workshop Featured at 21st Annual
Conference of Radiation Control Program
Directors
by Raymond Brandwein (FTS 475-8388)
and Fred Hodge (FTS 475-9640)
The twenty-first annual meeting of the Conference of
Radiation Control Program Directors (CRCPD) in Baton
Rouge, LA, featured a risk workshop, with concurrent
sessions on risk assessment, management, and
communication. Participants in the Risk Assessment
Workshop were introduced to the four-step process
developed by the National Academy of Science (NAS).
In the Risk Management Workshop, one of the case
studies required participants to assume the role of EPA
Administrator in making a decision on four source
categories of radionuclide emitters considered for
regulation under Section 112 of the Clean Air Act. Bill
Gunter, Director of the Office of Radiation Programs
(ORP) Criteria and Standards Division, provided a mock
briefing on the elements of the rulemaking. The
participants were then divided into small groups to make
their decisions on each category. In his report to the
General assembly of the CRCPD, the rapporteur for this
workshop noted how useful the experience was, by
"putting the shoe on the other foot," so that states had
the experience of dealing with the many factors which
must be considered in rulemaking at EPA.
The Risk Communication Workshop used a specially
modified one-day version of the course developed by
the Office of Policy, Planning and Evaluation (OPPE).
Concurrent sessions were held for almost 100
participants at the CRCPD annual meeting. Facilitators
who had completed the recent prototype course in
Annapolis (last issue of the Risk Assessment Review)
were Ray Brandwein, Jon Broadway, Doreen Hill, Peyton
Lewis, and Tony Wolbarst, all of ORP, and Andy
Schwarz, from OPPE's contractor, Temple, Barker and
Sloane, Inc. Because this workshop was considered so
useful, the Executive Director of CRCPD is exploring
making it available to other members who did not have
the opportunity to participate during the annual meeting.
Risk Assessment Forum Workshops Generate
Ideas
by Shirley G. Thomas (FTS 475-6743)
Review of Cancer Risk Assessment Guidelines
EPA's review of the 1986 cancer guidelines will utilize
information developed during two recent workshops to
help make decisions regarding changes in the
guidelines. The first workshop was held in January and
the second in June.
Workshop Report Available
The Risk Assessment Forum announced the availability
of the workshop report on "EPA Guidelines for Carcin-
ogen Risk Assessment" in the Federal Register, Vol. 54,
No. 77, Monday, April 24, 1989. The workshop report
highlights the major scientific issues discussed at a
meeting held on January 11-13, 1989, in Virginia Beach,
Virginia, where EPA assembled experts in various
aspects of carcinogen risk assessment to examine the
scientific foundation for certain aspects of the EPA's
1986 Carcinogen Risk Assessment Guidelines (51 FR
33992-34054, September 24, 1986).
Anyone interested in obtaining a single copy may

National Technical Information Service (NTIS), 5285 Port
Royal Road, Springfield, VA 22161. Please refer to EPA
No. EPA/625/3-89/015 when placing your order through
NTIS.
Workshop on Use of Human Evidence
A workshop on "The Use of Human Evidence in
Carcinogen Risk Assessment" was held at the
Georgetown Omni Hotel in Washington DC, June 26 -
27. Members of the public were invited to attend as
observers.
The workshop is part of a three-stage process for
reviewing and, if appropriate, revising EPA's Cancer
Risk Assessment Guidelines. The forum is now
completing the first stage of this review, which includes
several information-gathering activities for identifying
and defining scientific issues regarding the 1986
guidelines. In the second stage of the review, EPA
scientists will use information collected from workshop
panelists and others to develop and formally propose
changes in this risk assessment guidance. In the third
stage, any proposed changes would be submitted to
individual scientists for preliminary peer review and then
3

-------
to the general public, other federal agencies, and EPA's
Science Advisory Board for comment.
Information from the workshop and other sources will be
used to decide when and how the guidelines should be
revised.
Developmental Toxicants Guidelines
Amendments to EPA's 1986 Guidelines for
Developmental Toxicants were proposed in the Federal
Register on March 6, 1989. The notice, which proposes
the first set of amendments to any of the risk
assessment guidelines issued in 1986, announced a 90-
day public comment period that closed on June 5. Some
of the areas proposed for amendment include additional
guidance on maternal toxicity, dose response assess-
ment, and classification according to a weight-of-
evidence system.
Happenings at the Science Advisory Board
by Don Barnes (FTS 382-4126)
On a monthly basis, the Science Advisory Board is
developing a summary report of activities titled
"Happenings at the SAB." "Happenings" includes a list
of the meetings held in the past month, schedule for
meetings in the coming month, and status of reports and
other activities at the SAB (e.g., staff news, tentative
calendar of events for the next 3 months, etc.). To
receive copies of "Happenings," please contact Ms.
Joanna Foellmer at FTS 382-4126.
Geostatistical Environmental Assessment
Software
by Evan Englund (FTS 545-2248)
EPA's Environmental Monitoring Systems Laboratory
announced the availability of the Geostatistical
Environmental Assessment Software (Geo-EAS) at the
recent Risk Assessment Meeting in Seattle. Geo-EAS is
a collection of interactive software tools for performing
two-dimensional geostatistical analysis of spatially
distributed data. The programs provide for data file
management, data transformations, univariate statistics,
variogram analysis, cross validation, kriging, contour
mapping, post plots, and line/scatter graphs. Features
such as hierarchical menus, informative messages, full-
screen data entry, parameter files, and graphical
displays are used to provide a high degree of
interactivity, allowing users to easily alter parameters
and recalculate results.
Geostatistical methods are useful for site assessment
and monitoring situations where data are collected on a
spatial network of sampling locations, and are
particularly suited to cases where contour maps of
pollutant concentrations, or other variables, are desired.
Examples of environmental applications include lead and
cadmium concentrations in soils surrounding smelter
sites, outdoor atmospheric N02 concentrations in
metropolitan areas, and regional sulfate deposition in
rainfall. Kriging is a weighted moving average method
used to interpolate values from a sample data set onto a
grid of points for contouring. The kriging weights are
computed from a variogram, which measures the degree
of correlation among sample values in the area as a
function of the distance and direction between samples.
All Geo-EAS programs are controlled interactively
through menu screens which permit the user to select
options and enter control parameters. While default
choices for many parameters and options make the
program easier to use, the programs are structured to
avoid a "black box" approach to data analysis. Several
of the more complex programs permit the user to save
and read "parameter files." making it easy to quickly
rerun a program at a later date.
The system was designed to run under DOS (Disk
Operating System) on an IBM PC, XT, AT, PS2, or
compatible computer. Graphics capability is not required
but is highly recommended," as most programs will
produce graphics output. Graphics support is provided
for the Hercules monochrome graphics card, the Color
Graphics Adapter (CGA), and the Enhanced Graphics
Adapter (EGA). Six hundred forty kilobytes (Kbytes) of
random access memory (RAM) is required. An
arithmetic coprocessor chip is strongly recommended,
owing to the computationally intensive nature of the
programs, but is not required for use. Programs may be
run from the floppy diskette; however, a fixed disk is
required to use the programs from the system menu.
The system storage requirement is approximately three
megabytes. For hardcopy of results, a graphics printer
(IBM graphics compatible) is required. Support is
provided for plotters which accept HPGL plotting
commands.
EPA employees (and other government agencies or
academic institutions) may obtain a copy of the program
by sending the appropriate number of diskettes (PRE-
FORMATTED, PLEASE!) to the following address:
Evan J. Englund (Geo-EAS)
USEPA - EMSL-LV, EAD

III. Around the Regions
Region III
On June 15, 1989, Region III conducted a one-day
version of the Risk Communications course developed
by the Office of Policy, Planning and Evaluation, which
builds on the Workshop on Risk and Decision-making.
The course was attended by twenty supervisory and
technical staff from the regional office. Based on the
reaction and evaluation sheets, the course was well
received and very informative.
The course focuses on the perceptions of risk and the
seven cardinal rules of risk communication. The course
includes lectures intermixed with video tapes and
overhead slide presentations. Examples of EPA
communication, including the EDB, Dioxin and Marjol
Battery Superfund Site in Region III, reinforce the seven
cardinal rules and perceptions of risk.
The second offering of the course will be on July 13,
1989, following a one-day rendition of the Basic Risk
Assessment Workshop on July 12.
Contact: Jeff Burke, FTS 597-1177
Region VIII
The Region VIII Institute, in conjunction with the Office of
Research and Development, is sponsoring a series of
seminars on emerging environmental and health effects
research programs within the Agency.
These seminars will provide the opportunity for Office of
Research and Development (ORD) scientists to share
their research on risk reduction with regional and state
staff and public and private researchers. Through this
series, ORD researchers will gain valuable insights into
how these programs can be applied in the field.
Seminar topics include:
•' EPA's biomarkers of exposure research program -
Dr. Charles Nauman
•	New exposure assessment tools (such as RISK
ASSISTANT) - Dr~Seong Hwang and John Segna
•	Biomass combustion and utilization - Office of
Technology Transfer and Regulatory Support
More seminar topics will be added throughout the year.

Region V to Host Fifth Regional Risk
Assessment Meeting
At the Fourth Regional Risk Assessors meeting held in
Seattle, Washington, May 9 - 12, 1989, the following
poem was presented to Milt Clark and Region V, who
have agreed to host the next Regional Risk Assessment
meeting. The poem was written by Mike Watson, Region
X's toxicologist.
Onward to Region V: The Magic Continues ...
Q1 Star and LD50,
Mystic words so vague and shifty;
Work your risk assessment magic.
Modeling away the tragic.
Eye of newt! And non-stochastic!
How can science be so drastic?
Puzzles worthy of Houdini
Lie within the sliced linguini!
Time to pass the torch, we're thinkin',
Over to the Land of Lincoln.
There, beside the Great Lake silt;
Next year's hero - Look, it's Milt!
Wear this "MAGIC MERLIN CLOTHING!"
It will guard your from the loathing
Critics of our risk technique.
(20-20 wants a peek!)
Aristotle, Nostradamus -
(None of these an ignoramus),
Ancient heroes of our muse.
How could anyone refuse?
Gaping chasms bar the path.
Is it real or is it math?
Monte Carlo, co-promotion,
Paper boats upon the ocean.
May the prime-time ugly rumors
Say the rats have fewer tumors.
Peace and love from that attorney!
Hope and wisdom for your journey!
Wear them proudly, new convener!
May our world be safer, cleaner.
In a year, the time is fleeting,
Region Five will host this meeting.
Please watch future issues of the Risk Assessment
Review for further details on the plans for the meeting.
IV. Announcements
Modeling Workshops
The Office of Research and Development's Center for
Exposure Assessment Modeling (CEAM) located in
Athens, Georgia, will present two modeling workshops in
July. On July 10 - 14, 1989, CEAM will offer training on
the Stream Water Quality Model QUAL2EU and on July
24 - 27, 1989, they will offer training on the Exposure
and Bioaccumulation of Toxicants in Surface Waters.
The QUAL2EU Modeling Workshop is intended for
engineers and scientists who perform water quality
modeling. The workshop is designed for persons already
familiar with the basic concepts of water quality
modeling. Participants will review the theory used in the
model, but the primary objective of the workshop is to
5

-------
teach the use of the QUAL2EU and QUAL2EU-UNCAS
computer programs. The model is designed to evaluate
the effects on water quality of nutrients, BOD, DO,
coliforms, temperature and conservative materials.
QUAL2EU can also be used to evaluate the effects of
point sources of pollution and perform wasteload
allocations for NPDES dischargers. Included throughout
the workshop will be hands-on sessions using the
Athen's Environmental Research Laboratory's
computers. Uncertainty analysis, using the integrated
sensitivity, first order error analysis, and Monte Carlo
analysis capabilities of QUAL2EU-UNCAS will be
emphasized.
The workshop "Models on Exposure and
Bioaccumulation of Toxicants in Surface Waters" will
cover a variety of environmental models designed to aid
scientists and engineers in the management of pollution
control to achieve water quality goals. The purpose of
the workshop is to provide participants with the
knowledge and the tools to evaluate problems
associated with toxicants in surface waters. Lectures will
address the theory and principles that control chemical
transport, transformation, fate and biological impact of
pollutants in surface waters. The course will also provide
experience in the actual applications and operation of
the following models:
SARAH2: A steady state hazardous waste mixing
zone model.
EXAMSII: A steady state and quasi-dynamic model
for rapid evaluation of the behavior of
synthetic organic chemicals in surface
waters.
WASP4: A dynamic model for site-specific
evaluation of transport, transformation and
the fate of contaminants in surface waters.
WASTQX A WASP4 associated program that predicts
FOOD uptake and distribution throughout a user-
CHAIN described aquatic food chain.
Model
FGETS2: A toxicokinetic model that stimulates
bioaccumulation of non-polar organic
chemicals by fish.
There is no registration fee for the workshop(s). For
further information, please contact Ms. Joyce A. Wool,
ASci c/o USEPA ERL, College Station Road, Athens,
Georgia 30613-7799. Ms. Wool can be reached at (404)
546-3549.
Environmental Risk Assessment of Chemicals
On August 7 - 9, 1989, the Center for Professional
Advancement, located in East Brunswick, New Jersey,
will host a practical course on Environmental Risk
Assessment of Chemicals. This course covers a
practical approach to the principles of hazard
assessment and risk assessment that is necessary in the
permit application procedures, insurability of firms and
real estate "Due Diligence" transactions. The use of
practical data, rather than sophisticated toxicology and
pharmacokinetics, to assist the reviewer in applying
acceptable state-of-the-art standards to making these
determinations will be discussed in detail with
illustrations and examples. The emphasis is on the "how
to - hands-on" approach rather than on theoretical
considerations in arriving at conclusions.
The fee for the course is $895.00. For further
information, please contact the Center of Professional
Advancement, P. 0. Box 964, East Bri/nswick, New
Jersey 08816-0964. The center can be reached at (201)
613-4500.
Harvard School of Public Health - Risk Analysis
in Occupational and Environmental Health
Course • September 6-8, 1989
On September 6 - 8. 1989, Harvard University's School
of Public Health will provide a workshop on Risk
Analysis in Occupational and Environmental Health. The
three-day course will provide participants with detailed
information on the processes involved in risk analysis
and on handling uncertainties in risk assessment.
Participants will also gain practical experience in
defining control methods for health risks associated with
toxic agents. The course will build from a fundamental
knowledge of occupational health concerns and will
include:
•	The epidemiology of environmental and
occupational hazards,
•	The development of data through toxicological
studies,
•	The use of animal and other data as predictors of
human risk,
•	Benefit/cost analyses in the regulation of toxic
chemicals,
•	Federal specific and generic approaches to risk
assessment,
•	Sampling indoor and outdoor environments, and
•	Risk analysis within the context of the law.
To provide participants with direct experience in risk
management, the course emphasis will develop from
case studies of two toxic chemicals currently under
public health investigation: benzene, recognized as a
major occupational health concern, and daminozide
(ALAR), now undergoing close scrutiny as a concern for
environmental and public health.
The fee for the course is $695.00. For additional
information concerning the course and housing, please
contact the Harvard School of Public Health, Office of
Continuing Education, Department A, 677 Huntington
Avenue, L-23, Boston, Massachusetts 02115 or (617)
