ENVIRONMENTAL PROTECTION AGENCY
[FRL-6479-1]
Science Advisory Board; Notification of Public Advisory Committee
Meeting
Pursuant to the Federal Advisory Committee Act, Public Law 92-463,
notice is hereby given that the Environmental Models Subcommittee (EMS)
of the Science Advisory Board's (SAB) Executive Committee, will meet
Monday and Tuesday December 13 and 14, 1999 in the Environmental
Research Center (ERC) Classroom No. 2, Highway 54 & Alexander Drive, at
the U.S. Environmental Protection Agency, Research Triangle Park, North
Carolina 27711. The meeting will begin at 9:00 am on December 13 and
adjourn no later than 5:00 pm on December 14th (Eastern Time). This
meeting is open to the public, however, seating is limited and
available on a first come basis. Documents that are the subject of SAB
reviews are normally available from the originating U.S. Environmental
Protection Agency (EPA) office and are not available from the SAB
Office. Public drafts of SAB reports are available to the Agency and
the public from the SAB office. Details on availability are noted
below.
Purpose
The purpose of this meeting is to: (a) Conduct an advisory on the
Agency's Total Risk Integrated Methodology (TRIM) as part of a
continuing review of this modeling system which is being developed by
the Office of Air and Radiation (OAR), Office of Air Quality Planning
and Standards (OAQPS) to support the Agency's regulatory decision
making for air pollutants; (b) receive an update and briefing on the
workplan for implementation of activities of the Council for Regulatory
Environmental Modeling (CREM); and (c) conduct planning for the Fiscal
Year 2000 activities of the Environmental Models Subcommittee (EMS) of
the Science Advisory Board (SAB), such as a possible future review of
the MINTEQA2 model.
SAB Advisory on TRIM
The Agency's OAR is developing TRIM which is intended to support
the Agency's regulatory decision making for air pollutants. The intent
in creating TRIM with a flexible framework using open architecture is
that it will provide the Agency with essential multi-media, multi-
pathway air pollutant modeling capabilities in the short term, as well
as allow the Agency to take advantage of future advances made over the
longer term modeling and monitoring research. The basic charge
questions the Agency is raising to the SAB's EMS deal with the overall
TRIM system, as well as the three individual modules. The charge
questions on the overall TRIM system deal with the TRIM's current
design, modular approach, and open architecture, as well as the
scientific reasonableness of plans for addressing uncertainty and
variability. Questions are being asked by the Agency to the SAB's EMS
regarding improvements in the ability of TRIM.FaTE to incorporate
outputs from external models, to model chemical transformation and
metals, and to incorporate seasonal processes. An additional question
is focused on issues associated with the incorporation of both
horizontal and vertical atmospheric dispersion and diffusion
algorithms, as well as what alternate methods might be recommended to
incorporate these algorithms. The SAB's EMS will also be asked to
critique an evaluation plan for TRIM.FaTE. In addition, questions are
being raised with regard to the adequacy of the TRIM.Expo proposed
conceptual design and specific algorithms chosen in the modeling
framework, as well as the adequacy of the conceptual plan for the
TRIM.Risk module.
The SAB's EMS will also be updated on the activities and work plan
for implementation of the Committee for Environmental Regulatory
Modeling (CREM).
For Further Information
Copies of the review documents and any background materials for the
review are not available from the SAB. The TRIM review documents are
available from the program office by contacting Dr. Deirdre Murphy by
telephone at (919) 541-0729; by fax at (919) 541-0237, or by E-mail at
<[email protected]>. The documents that are being provided to the
SAB's EMS include the following: (1) TRIM Status Report, (2) TRIM.FaTE
Technical Support Document, Vol. I, (3) TRIM.FaTE Technical Support
Document, Vol. II, and (4) TRIM.EXPO Technical Support Document. The
CREM update will be available to the Subcommittee as well as to members
of the public at the meeting. You may call, fax or E-mail the program
office for information regarding the status of

Any member of the public wishing further information concerning the
meeting should contact Dr. K. Jack Kooyoomjian, Designated Federal
Officer for the Environmental Models Subcommittee, Science Advisory
Board (1400A), U.S. Environmental Protection Agency, 401 M Street, SW.,

mail at <[email protected]>. Anyone wishing to make an oral
presentation at the meeting must contact Dr. Kooyoomjian in writing no
later than close of business Tuesday, December 7, 1999, at the above
address, fax or e-mail. The request should identify the name of the
individual who will make the presentation and an outline of the issues
to be addressed. Copies of the draft meeting agenda are available from
Ms. Dorothy Clark, Management Assistant, Committee Operations Staff at
(202) 564-4537; by fax at (202) 501-0582; or by E-mail at
<[email protected]>.
Providing Oral or Written Comments at SAB Meetings
The Science Advisory Board expects that public statements presented
at its meetings will not repeat previously submitted oral or written
statements. In general, each individual or group making an oral
presentation will be limited to a total time of ten minutes. This time
may be reduced at the discretion of the SAB, depending on meeting
circumstances. Oral presentations at teleconferences will normally be
limited to three minutes per speaker or organization. Written comments
(at least 35 copies) received in the SAB Staff Office sufficiently
prior to a meeting date, may be mailed to the relevant SAB committee or
subcommittee prior to its meeting; comments received too close to the
meeting date will normally be provided to the committee at its meeting.
Written comments, which may be of any length, may be provided to the
relevant committee or subcommittee up until the time of the meeting.
Information concerning the Science Advisory Board, its structure,
function, and composition, may be found in The Annual Report of the
Staff Director which is available from the SAB Committee Evaluation and
Support Staff (CESS) by contacting US EPA, Science Advisory Board
(1400A), Attention: CESS, 401 M Street, SW, Washington, DC 20460 or via
fax (202) 501-0256. Additional information concerning the SAB can be
