On February 12, 2009, EPA’s Office of Pesticide Programs, Office of
Water, Office of Research and Development, and Office of General Counsel
met with Syngenta Crop Protection, Inc. to discuss the status of
implementation of the eco-monitoring portion of the atrazine DCI. 
Meeting participants discussed the revisions that had been made to the
Community Aquatic Simulation Model (CASM) since the 2007 Scientific
Advisory Panel (SAP), as well as the pros and cons of using CASM for
assessing the ecological level of concern (LOC) for atrazine exposures
in freshwater systems.  The participants also discussed an
“Alternative Approach” to CASM and its potential use for LOC
development.  After discussion of the two approaches, the Environmental
Fate and Effects Division (EFED) outlined the next steps to prepare for
the May 2009 Atrazine Eco-Monitoring SAP, and requested additional data
from Syngenta.
