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.
