Dear Panel Members:

Attached are some additional background materials for the January 9-12,
2007 FIFRA SAP Meeting to review and consider worker exposure assessment
methods.

The Office of Pesticide Programs (OPP)  provided to the Panel material
prepared by the Agricultural Handler  Exposure Task Force (AHETF).  This
material includes a document entitled:  Procedures for Determining the
Required Number of Clusters and Monitoring Units per Cluster to Achieve
Benchmark Adequacy.   This document was provided to the Panel on the
CD-ROM  as III.F.  Sample Size Report.   

In reviewing this document and its associated tables and simulations, 
it became apparent to the Agency that some Panelists may wish to receive
additional background material on how these simulations were performed. 
Specifically, Panelists may wish to review and comment on  the SAS code
used by the AHETF to generate these simulation results.  As such, the
Task Force was asked to provide this code to OPP so that it could be
distributed to the Panel and placed in the docket.  Please find this
code attached (in both *.sas and *.doc formats).     

In addition, OPP has prepared a spreadsheet providing the hand
measurement data in a format that may facilitate the Panel's review
(note:  these data were already provided in the original submission to
the panel; this spreadsheet is just a re-formatting of that data). 
Please find this spreadsheet attached in Microsoft Excel format.

Please let us know if you have any difficulty opening or reading these
files or would otherwise like to receive this information in a different
format.

Thank you.
