EFED Exposure Modeling Work Group; Notice of Public Meeting

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.


[[Page 16817]]

SUMMARY: This notice announces an April meeting of the Exposure 
Modeling Work Group (EMWG). The EMWG meetings are sponsored by the 
Office of Pesticide Programs' Environmental Fate and Effects Division 
(EFED). The theme for this meeting is ``pesticides in air'' and will 
include presentations on pesticide volatilization from soil, pesticide 
spray drift and pesticide in rain water. The purpose of the meetings is 
to update those in the pesticide regulatory community on advances in 
estimating pesticide concentrations in media of concern through 
computer simulation. Improvements in estimation of pesticide exposure 
lead directly to improvements in estimation of risk both to the 
environment and to human health.

DATES: The meeting will be held on April 11, 2005 from 9 a.m. to 3 p.m.

ADDRESSES: The meeting will be held at 1126 Crystal Mall 2, 
1801 S. Bell St., Arlington, VA 22202.

FOR FURTHER INFORMATION CONTACT: Ronald Parker, Environmental Fate and 
Effects Division (7507C), Office of Pesticide Programs, Environmental 
Protection Agency, 1200 Pennsylvania Ave., NW., Washington, DC 20460-
0001; telephone number: (703) 305-5505, fax number: (703) 305-6309; e-

II. Background

    Exposure Modeling Work Group Meetings are sponsored by EFED, and 
are held quarterly. The purpose of the meetings is to stimulate 
discussion on the subject of pesticide environmental fate and transport 
computer modeling, with the objective of improving the science and 
practice of estimating exposure to pesticides. Media of concern include 
surface water, ground water, soil, air, items that may serve as food 
for wildlife and items that may be food for human consumption. 
Presentations are sometimes focused around a theme.
    The agenda for the meeting follows:
    1. Welcome and Introductions - (9 a.m. - 9:05 a.m.)
    2. Old Action Items - (9:05 a.m. - 9:15 a.m.)
    3. Brief Updates (9:15 a.m. - 9:45 a.m.)
     PRZM3.12.2 Evaluation (J. Hetrick)
     EXPRESS (R. Parker)
     Carbamate Cumulative Assessment (N. Thurman)
