USDA Update: USDA Conference Call for Carbaryl

April 25, 2003

The USDA conference call to discuss the revised risk assessment for Carbaryl is scheduled for Wednesday, May 7 at 1:00 p.m. to 3:00 p.m.. Both EPA and the Registrant will be participating.

The Call-in Numbers are (800) 867-6144 or (202) 554-1742 Access Code: 5746

Since the public comment period for the revised risk assessment closes June 2, and the list of registered crops are extensive, we would like to identify the critical uses for carbaryl before the call. For these crops, we would like to look at the use assumptions considered in the risk assessment and the resulting changes to the REIs.

The first question: Is carbaryl important/valuable for your crop?

If the answer is yes, we need to make sure the labeled application rates and maximum number of applications per season reflect your actual use. The application rates and number of applications considered in the revised risk assessment can be found in Table 4 (page 24) of the Revised Phase 5 Occupational and Residential Exposure Assessment.

Attached is a summary of the REIs proposed in the assessment. These REIs are derived without the benefit of the most recent transfer coefficients from the Agricultural Re-Entry Task Force (ARTF) data submitted to the Agency in November 2001.

Are these REIs acceptable for your crop?

If you have any questions, let me know. Also, the Chemical Review Manager at EPA, Tony Britten (britten.anthony@epa.gov (703) 308-8179) is available to answer any of your specific questions.
