Request From: Steve Toth
Date Requested: Aug 09, 2006
Request: Please note the following request for comments on the formetanate HCl IRED. If you or someone in your state wishes to comment on the Formetanate HCl IRED, please see the instructions below. Also please copy any comments to me and Teung Chin so that we can document them and Teung can follow up with EPA. Note the August 28, 2006 deadline from EPA for comments. Thanks. Steve Toth ----------------------------------------- EPA issued the formetanate HCl IRED for public comment on June 28, 2006. Public comments must be received by August 28, 2006. If you have comments, please send them to the EPA Docket and cc: myself so we can follow-up on your behalf with EPA. - 6/28/06 FR Notice Announcement of Publication of the Formetanate HCl IRED http://www.epa.gov/fedrgstr/EPA-PEST/2006/June/Day-28/p5837.htm To review all the EPA documents and risk assessments and to file comments, go to www.regulations.gov.

Most of the estimated acute exposure from food was determined to result from late season uses of formetanate HCl on apples. Deletion of the late season apple use results in an acute dietary (food + water) risk within an acceptable range of the level of concern. Drinking water is the largest contributor to acute dietary exposure when late season uses are excluded - Risk Mitigation The following risk mitigation measures are required for formetanate HCl to address risks of concern. - To mitigate dietary risks: - Amend labels to prohibit late season applications to apples. - To mitigate occupational risks to handlers: - Revise labels to prohibit aerial application for orchard crops. - Revise labels to require closed cabs for applicators using airblast sprayers on orchard fruit. - Revise labels to require closed cabs for human flaggers for aerial application - Revise labels by reducing the PPE to a single layer with a PF5 respirator for applicators using groundboom equipment for alfalfa for seed. Although the Agency is concerned with the MOE for the mixing/loading scenario for aerial application on alfalfa grown for seed, EPA recognizes that the use provides high benefits to the grower community. In addition, EPA recognizes that the inputs used to calculate the inhalation assessment were based on conservative assumptions. The Agency is requiring additional data which will provide a more refined estimate of the inhalation risks for workers handling formetanate HCl. EPA believes these data will confirm the conclusion that no mitigation is appropriate for the mixer/loader scenario for aerial applications to alfalfa. - To mitigate occupational risks to post-application agricultural workers: - Revise labels to require a 10 day REI for citrus, an 8 day REI for pome fruit and stone fruits, and a 6 day REI for alfalfa. - To mitigate ecological risk: - No ecological specific mitigation is required. Some of the human health mitigation will result in lower non-target organism exposures. Regulatory Conclusion EPA has determined that all supported uses of formetanate HCl are eligible for reregistration (except for late season uses on apples) provided that registrants implement risk mitigation measures described in the IRED and that cumulative risks of the N-methyl carbamates do not exceed EPA’s level of concern.
