-------
1. Welcome, Roll Call, and Opening Remarks

The DFO took roll, introduced herself, and opened the meeting by saying that EPI Suite Review
Panel was begins its review of the EPI Suite Model on today's call.

The DFO explained that the EPI Suite Review Panel is a panel of the Science Advisory Board,
which is a chartered committee under the Federal Advisory Committee Act ( FACA). The
chartered board will consider the Panel's report before it is transmitted to the Administrator.

Such reviews almost always require editorial improvements before the report can be finalized
and transmitted. It is possible, but rare, for the Board to return a report to a Panel for further
work.

This Panel was formed according to the process detailed in the draft booklet "Overview of the
Panel Formation Process at the EPA Science Advisory Board" available on the SAB website. A
widecast Federal Register notice was published on January 31, 2005 allowing individuals and
institutions to nominate candidates for consideration for service on the Panel, a short list of
candidates was posted for comment on September 21, 2005, and the final panel formed after the
SAB Staff completed its review of information regarding conflicts of interest, appearance of lack
of impartiality, and appropriate balance and breadth of expertise, knowledge and experience
needed to address the charge.

All members of this panel have provided information, including confidential financial statements
protected under the Privacy Act ands information about points of view on the matter to be
discussed. The SAB's Ethics and FACA Policy Officer, who is also an Alternate Deputy Ethics
Official, has re viewed all these materials. This official, together with the SAB Staff Office
Director, who is the Deputy Ethics Official for the SAB, in consultation with the SAB Ethics and
FACA Policy Officer, who is the Alternate Deputy Ethics Official for the SAB, have determined
that there are no outstanding ethics issues concerning any of the panelists. No waivers, were
needed or considered for any of the panelists. In addition, the panelists have completed a one
hour on-line ethics course specifically designed for the SAB.

All discussions and deliberations of the panel, its interactions as a body or as individual panelists
with the public, including the Agency, as they relate to this review, are to be conducted in my
presence. As the Designated Federal Officer I am required to ensure that the requirements of
FACA are met. In essence, I act as a chaperone for the process.

We have received one written public comment which has been posted at our website. The slides
for the Agency's presentation have been posted there and emailed to those individuals who
contacted us to say they would be present on this call. There have been no requests from the
public for oral comment on the agenda for today's call.

She then turned the meeting over to the SAB 's Associated Director for Science, Tony
Maciorowksi, for a brief welcome and then to the Chair, Dr. Michael McFarland .

2. Briefings by OPPT

At 1:20 Neil Patel introduced the Panel to the structure of the Office. The attached handout from
OPPT, entitled, Overview ofEPI Suite™: Software for Chemical Property and Fate Estimation,
(pages 1-4) capture his major points. OPPT is responsible for assuring that industrial chemicals
for sale and use in the U.S. do not pose unacceptable risks to human health or the environment
This is accomplished through pollution prevention, safer chemicals, risk reduction, risk
management and public understanding. OPPT is responsible for: Pre-manufacture review of
new industrial chemicals; Testing, assessment, and risk reduction of existing industrial
chemicals; Management of "national chemicals" (e.g. PCBs); International chemical issues;
Pollution prevention advocacy; Partnership programs, e.g. HPVC Challenge, Green Suppliers
Network, DfE, and Green Chemistry. His remarks concerning the partnership programs were
more descriptive than the handout; partnerships include the High Production Volume Challenge,
Green Suppliers Network, Design for the Environment, and Green Chemistry. In all of these,
physical-chemical properties are important. They use data where available. Where not are not
available OPPT needs to estimate the properties. There were no questions for Patel.

At 1:20 Bob Boethling began a briefing on EPI Suite using slides (5 - 36). He described EPI
Suite, which estimates physical/chemical properties and environmental fate and transport and
Estimates physical/chemical properties and environmental fate and transport and runs estimation
programs sequentially with chemical structure as only input. Again, his presentation followed
the attached slides very closely and he was careful to state which slide he was speaking from at
any particular time.

Boethling addressed components ofEPI Suite using Slides 8-1. Dzombak asked for a little more
information on Biowin (Slide 11). Boethling said the full literature is available through the EPI
Suite program. Biowin 1 and 2 were the oldest, originally called the biodegradability probability
program. The summary of the mostly qualitative weight of evidence evaluations is captured in
the environmental fate data base. The next two are Biowin 3 and 4 which is the result of a
survey of biodegradation experts asked for their advice on the biodegradability of 200
compounds. Biowin 5 and 6 are the most recent. They model the famous Midi date of 800 -
1000 chemicals.

Biowin 1 and 2 provide a binary classification to predict speed of biodegradation. Biowin 2 and
4 provide a semi-quantitative estimate of biodegradation in days, weeks, months or longer.
Biowin 5 and 6 give a fast but based on the Midi 301C data

Slide 13 shows the opening screen as it appears to users and Slide 14 provides an extensive list
of caveats. The next slides addressed method details, accuracy and validation. At slide 18,
Miriam Diamond, who had looked at the statistics in the help file, asked if there was a policy
direction as to what was acceptable. Boethling responded that he knew of none and observed it
was a good SAB type issue. Fehrenbacher also thought there was no standard policy on what
would be an acceptable level of accuracy. She thinks it is a case by case determination.

-------
Slide 23 describes the users of OPPT models, not just EPI Suite. Many different kinds of people
and organizations use the models (industry, research consultants, federal employees, state and
local governments, EPA offices other than OPPT, and others).

Slide 24 provides information about the use of EPI Suite in OPPT programs. Dzombak, who
gathered EPI Suite is not especially useful for metals or their compounds, asked about the kind
of data required for the PMN programs, especially data that EPA might prefer to use instead of
these tools. Boethling responded that the submitter is only required to submit what data is in its
possession, but there is no up-front requirement for testing. OPPT would like to receive
measured data for everything EPI Suite estimates and more. Only 5% of the submissions
include any basic physical-chemical data. That's why EPI Suite is used in PMN assessments and
other programs where they do not have measured values.

Bob Chinery asked if there were actionable regulatory criteria for physical-chemical values.
Boethling thought there were criteria for the persistent, bioaccumulative, and toxic substances.
He's concerned about Chinery's use of the word "actionable" as he doubts any action under
TSCA has every been taken on a KOW alone. EPI Suite is also used to provide inputs to ECO
SAR. ECOSAR (Ecological Structure Activity Relationships) is a personal computer software
program that estimates the toxicity of chemicals used in industry and discharged into water. The
program predicts the toxicity of industrial chemicals to aquatic organisms such as fish,
invertebrates, and algae by using Structure Activity Relationships (SARs). The program
estimates a chemical's acute (short-term) toxicity and, when available, chronic (long-term or
delayed) toxicity. EPI Suite (and other programs) can be used to estimate the octanol/water
partitioning coefficient (Kow) when measured values are not available. The coefficient is an
input to ECOSAR. ECOSAR is not included in this review; another office is responsible for
ECOSAR.

Diamond asked whether ions as well as protonated compounds were addressed by EPI Suite;
Boething agreed that was the case and discussed the difficulties (and expenses) of programs that
would estimate the relevant values, including the freely available SPARC. SPARC is a general
purpose calculator for situations where suitable measured values are not available. Examples
include newly-developed chemicals, those that have had little environmentally related data
collection, or where chemical parameters are not available at an environmentally relevant
temperature or pH. SPARC Performs Automated Reasoning in Chemistry (SPARC) was jointly
developed by US EPA and the University of Georgia.

When Parkerton asked if OPPT uses SPARC as a check against EPIWIN, Boethling reponded,
"occassionally". Parkerton then asked whether there was a process by which OPPT regularly
and systematically reviews new data on model predictions. Boethling said it is done as funding
permits, which it doesn't very much. Salvito spoke about altering the SMILES notation to
change the prediction. A member of the public, Scrivener, said they have some correction
factors for ionizable compounds if you know the pH of the environment in which they will find
themselves. Boethling isn't familiar with it, but it sounds like the kind of technology that
should get more attention.

5

-------
Using slide 26, Boethling spoke to the High Production Volume Chemicals, a data intensive
program.

Slide 27 illustrates the combination of user-friendly software with a policy that allows some
estimates. Sometimes applicants submit estimated values instead of measured values even where
the measured values exist. The combination could make EPI Suite harder to use. Right now
OPPT is adding information, as illustrated on slides 28 - 29. They would welcome suggestions.

The remaining slides provide information on recent and ongoing changes in EPI Suite. Slides 30
-35 describes the last major changes in the version of November 04 which, in its technical
aspects, is the same as what the Panel is reviewing. Slide 36 describes additional changes that
are planned. Deborah Bennett asked about how to get more information on how to get more
information on these changes. Boethling gave an example. It is an ongoing work assignment.
The SAB has not been asked to review these plans. Fehrenbacher said this is outside the scope
of the review, panelist noted that the last charge question addresses improvements to EPI Suite.

Cowan- Ellsberry asked about how estimates in one module affected others. In response to a
question on multiple values in the literature, Boethling noted that the physical property data base
displays selected values, not all values. Slide 29, under data quality considerations, provides a
description of how these decisions are made. Boethling thinks this is an area where EPA is
making improvements and can do more.

Parkerton asked about experimental values, observing that sometimes a short description of the
reference, not a full citation is provided. HELP talks about the experimental data base, but that
isn't so useful. Even recognizing that not all the data are included, how do you get the full
reference for the selected value used? Boethling responded that some modules list the full
references for all the data. PhysProp, however, is not so smooth. You have to go to the Syracuse
Data Base linked files to get the full reference.

3. Charge to the Panel and Discussion

At 2:15 McFarland thanked Patel and Boethling and began discussion of the charge. OPPT had
officially transmitted the charge after the preliminary assignments had been made. The chair and
DFO asked the Agency to point out any substantive changes to the charge as they are discussed.
Addressing the preliminary charge question-by-question, he asked the Panel what additional
information was needed to provide a basis for responding. Panel members also sought guidance
on the depth of the response desired.

The difficulties were question specific. Some are easily addressed now. The more difficult ones
are about validation and appropriate use. While the Panelists can do something now, they cannot
complete their responses until they have more information. Therefore, they hope to have more
material from EPA, especially on uses, before the weekend. Fehrenbacher said OPPT can
provide references to the panel before the weekend, but thinks uses will best be addressed by
presentation.

Deborah H. Bennett, Ph.D. is Assistant Professor of Environmental and
Occupational Health in the Department of Public Health Sciences at the University of
California Davis. She received an M.S. and Ph.D. in Mechanical Engineering from the
University of California, Berkely and a B.S. in Mechanical Engineering from the
University of California, Los Angeles.Her research focuses on the fate, transport, and
exposure to chemicals in a multimedia environment within the context of environmental
risk assessment. Current research interests fall into three areas: development of an
indoor fugacity model to assess exposures resulting from indoor releases of pesticides
and other organic compounds; exposure to Hazardous Air Pollutants (HAPs) in various
indoor microenvironments through modeling and monitoring; and methods for
quantifying, and uses for, the Intake Fraction of compounds. The Intake Fraction is the
integrated incremental intake of a pollutant released from a source or source category
and summed over all exposed individual per unit of emitted pollutant. She has also
developed methods for quantifying the spatial range and temporal persistence of
organic pollutants in a multimedia environment, a classification system for persistent
pollutants and evaluated the use of long range transport models in the context of
regulatory decisions through a model comparison. A list of Dr. Bennett's publications
may be found at http://phs.ucdavis.edu/Facultv/Bennett.php.

Preliminary Draft Charge Distributed to EPI Suite Review Panel January 13, 2006

General charge to the Science Advisory Board

The Agency is primarily interested in the SAB's review of the supporting science,
functionality, and appropriate use of EPI Suite. While SAB should feel free to comment
broadly, specific responses to the following technical questions would be welcomed.

1. Supporting Science

A. Comprehensiveness

i.	Are there additional properties which should be included in
upgrades to EPI Suite for its various specified uses (PMN,
P2, ???)? (An example might be Characteristic Travel
Distance.) Can any be dropped?

ii.	Are there additional sets of existing measured data which
should be included in upgrades to EPI Suite? Are there
specific measurements with the potential to improve EPI
Suite estimates so much that an effort should be made to
collect them?

iii.	Are there other capabilities that should be included in
upgrades to EPI Suite? The Agency is especially interested
in the SAB's views on uncertainty analysis and if/how
information on how good the estimates are can be conveyed
to users.

B. Method accuracy and validation

i.	Is the accuracy of the modules in the EPI Suite sufficient for
its various specified uses?

ii.	Have the modules been adequately validated, and have they
been published in the peer-reviewed technical literature or
elsewhere?

iii.	Are some modules more accurate/better validated than
others, and if so, which need more work?

iv.	To the extent that modules work together to generate
estimates, do they do so correctly?

20

-------
C. Estimation Methods and Alternates

i.	Are the estimation methods in EPI Suite up-to-date and
generally accepted by the scientific community for its various
specified uses?

ii.	Are there other estimation methods which should be
considered in upgrading EPI Suite?

2.	Functionality (Program documentation; user interface; convenience

features)

A.	How convenient is the software and does it have all the necessary
features?

B.	Are there places where EPI Suite user's guide (and other program
documentation) does not clearly explain EPI's design and use?
How can these be improved?

C.	Are there aspects of the user interface (i.e., the initial,
structure/data entry screen; and the results screens) that need to
be corrected, redesigned, or otherwise improved? Do the results
screens display all the desired information?

D.	Currently one enters EPI Suite using SMILES and CAS; are there
other ways to describe the structure (e.g., ability to input a structure
by drawing it), that should be added?

E.	The EPI Suite has many convenience features, such as the ability
to accept batchwise entry of chemical structures, and automatic
display of measured values for some (but not all) properties. Are
there other features that could enhance convenience and overall
utility for users?

F.	Are property estimates expressed in units that are easily
understood by a broad cross section of potential users, not just
scientists and engineers with advanced technical training?

G.	Is adequate information on accuracy/validation conveyed to the
user by the program documentation and/or the program itself?

3.	Appropriate Use

21

-------
A.	Currently Identified Uses: review of PMNs, P2 decisions, predicting
physical/chemical properties and environmental fate and transport
properties for HPV Challenge chemicals, to begin the assessment
of exposure, and other routine OPPT uses. It is important to
understand that EPI Suite is intended to be used in the absence of
measured data and not take their place.

i.	Is the science incorporated into EPI Suite adequate for each
of these current uses?

ii.	If not, what improvements are needed to make EPI Suite
adequate and what alternate approach could be used in the
interim?

B.	Potential Additional Uses

I'm not sure whether you responded to these or not, but they've gotten
lost in the shuffle one way or another. Can you look them over and let
me know?
