EPA Revised Human Health Assessment Published for Comments

01/13/2015 -

Today EPA published in the Federal Register (Federal Register Volume 80, Number 9 (Wednesday, January 14, 2015), the notice of availability of the revised human health assessment for chlorpyrifos and the opening of the docket for a 60-day public comment period (EPA-HQ-OPP-2008-0850 at http://www.regulations.gov). The deadline for comments was announced as March 16 [EPA has recently extended this to April 30, 2015]. EPA made these materials public on December 29, 2014, and this notice announces the official opening of the comment period. This assessment is another step in the registration process for chlorpyrifos. Dow AgroSciences is closely reviewing the assessment, and expects to share more information as we progress.

While Dow AgroSciences believes that some of the conclusions of EPA’s draft assessment can be improved with further evaluation, we consider the use of state-of-the-art chlorpyrifos pharmacokinetic (PBPK) modeling to be a major step forward in regulatory evaluations. We believe that the same rigorous approach and process could be used to address other outstanding regulatory issues (e.g., Food Quality Protection Act safety factors, worker exposures, exposures from drinking water, epidemiology studies, etc...), and that many of these issues could be resolved with such assessments.
