SUMMARY:

EPA is announcing a public technical briefing for August 22, 2001, to provide background information on cumulative risk assessment methods, in general, and the current status of the work on the organophosphate (OP) cumulative risk assessment. Particular attention will be given to the hazard portion of the OP assessment. For cumulative assessments, before a risk assessment can be done, the chemicals must be ranked according to their ability to produce the toxic effect of concern. This ability is quantified by a “potency” value. After the potency of each chemical is calculated, an index chemical is selected. This method to estimate the relative potency has been termed the “relative potency factor” method. The result of the method is the determination of a relative potency factor (RPF) for each chemical. The briefing will focus on the recently released paper, “Preliminary Cumulative Hazard and Dose-Response Assessment for Organophosphorus Pesticides and Points of Departure for Cholinesterase Inhibition,” which explains the method that has been used to determine the relative potency factors for the OPs and the selection of the index chemical. This paper will also be the subject of a meeting of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) Scientific Advisory Panel (SAP) on September 5-6, 2001. At the technical briefing, the hazard methodology will be explained in some detail and in terms appropriate for a non-scientific audience.

DATES:

The meeting will be held on Wednesday, August 22, 2001, from 9 a.m. to 5 p.m.

ADDRESSES:

The meeting will be held at the Hilton Alexandria Old Town, 1767 King Street, Alexandria, VA (directly across from the King Street Metro Station).
