Subject: Aldicarb - EPA Request for Benefits Information

Attachment 1
Attachment 2

Dear Colleagues:

On May 17, EPA released its health effects risk assessment for aldicarb and related documents for a 60-day public comment period. Public comments on the risk assessment must be received by the EPA Public Docket by July 17, 2006 as part of its Reregistration Eligibility Decision (RED) for the pesticide.

All the EPA risk assessment documents may be reviewed in the EPA docket under Docket Identification Number "EPA-HQ-OPP-2005-0163" at http://www.regulations.gov . Enter the Docket identification Number into the appropriate space in the "Advanced Search" tab and in the "Docket ID" space.

EPA considered the use or proposed use of aldicarb on the following crops: Bananas (proposed imported tolerance) Citrus, Other (includes kumquats, limes, tangelos and tangerines), Grapefruit, Lemons, Oranges, Pecans, Potatoes, Sweet Potatoes, Yams, Beans/Peas, Dry, Beans/Peas, Green, Sorghum, Alfalfa, Peanuts, Soybeans, Sunflower, Cotton, Sugar Beets, Sugarcane, Coffee (imported), and Tobacco.

The following benefits information is needed:

In what regions (state/county, etc.) of the U.S. is aldicarb use occurring? What is the percent crop treated in the states where aldicarb is used? (this is especially important information for potatoes)

What are the pests that aldicarb is critical for controlling?

What are the details of typical usage patterns (e.g., number of applications per season, use rate per application, acres treated, and time of application in the season?)

What worker activities typically occur when aldicarb is applied?

What alternatives, if any, are available to replace aldicarb?

Please provide as much detail and documentation in your comments as possible so that the Agency is fully informed in its decision-making.

The EPA May 17 Federal Register provides additional information including how to submit your comments to the docket: http://a257.g.akamaitech.net/7/257/2422/01jan20061800/edocket.access.gpo.gov/2006/E6-7496.htm

Besides submitting your comments directly to the EPA public docket, please also send a copy to teung.f.chin@usda.gov and sherrie.kinard@epa.gov so USDA and EPA may better coordinate.

For your information, EPA is also requesting interested parties:

1. To provide comments and input on the Agency's risk assessments for aldicarb. Such comments and input could address, for example, the availability of additional data to further refine the risk assessments, such as, additional toxicological data, worker exposure data, and usage information, or could address the Agency's risk assessment methodologies and assumptions as applied to this specific pesticide.

2. To provide risk management proposals for aldicarb. Risks of concern associated with the use of aldicarb are: acute dietary risk estimates for the general U.S. population and all population subgroups at the 99.9th percentile of exposure; acute aggregate food and water risk estimates for adults and children; and worker risk estimates for most mixers, loaders and applicators.

3. To submit risk management proposals for ecological risks of concern including those to birds, mammals, fresh water and marine fish and invertebrates. In targeting these risks of concern, the Agency solicits information on effective and practical risk reduction measures."
