Pesticide Drift in Human Health and Ecological Risk Assessments

We evaluate the potential for pesticide drift as a routine part of our human health and ecological risk assessments. We are proposing improvements to our current methods for

estimating off-site drift in these assessments, and
making decisions for use restrictions on pesticide labels.

These proposed improved pesticide drift methods are available in "Consideration of Spray Drift in Pesticide Risk Assessment" (Docket #EPA-HQ-OPP-2013-0676 at www.regulations.gov). The public comment period for these draft documents closed on March 31, 2014.
