MAJOR FORMETANATE HCL IRED REGULATORY CONCLUSIONS
- Acute Dietary Risk
The resulting acute dietary exposure and risk estimates for food and water
exceed EPA’s level of concern for the U.S. population and all reported
population subgroups. 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.
