Supplementary Information

This notice extends the public comment period established in the Federal Register of November 9, 2011 (76 FR 69726) (FRL-8888-9). In that notice, the Agency announced the availability of EPA's cumulative risk assessment for the pyrethroids. Based on this assessment, the EPA concluded that the cumulative risks from existing pyrethroid uses are below the Agency's level of concern. Because this cumulative risk assessment uses a number of very conservative assumptions, EPA provided an opportunity, through that notice, for interested parties to provide comments and input on any additional information that may be used to refine the very conservative nature of the pyrethroid cumulative risk assessment.

The Agency has received two requests to extend the comment period based on the complexity of the issue. The submitters are Beyond Pesticides and a member of the public. EPA is hereby extending the comment period, which was set to end on January 9, 2012, to February 8, 2012.

To submit comments, or access the docket, please follow the detailed instructions as provided under ADDRESSES in the November 9, 2011 Federal Register document. If you have questions, consult the person listed under FOR FURTHER INFORMATION CONTACT.
