USA: Chlorpyrifos

The US Environmental Protection Agency (EPA) published an Order denying a petition of revocation of all tolerances for the pesticide chlorpyrifos and cancellation of all chlorpyrifos registrations.EPA has concluded that “despite several years of study, the science addressing neurodevelopmental effects remains unresolved and that further evaluation of the science during the remaining time for completion of registration review is warranted to achieve greater certainty as to whether the potential exists for adverse neurodevelopmental effects to occur from current human exposures to chlorpyrifos”. EPA shall complete the registration review by October 1, 2022.This Order was effective on April 5, 2017. Objection and request should be submitted on or before June 5, 2017.Federal Register Vol. 82, No. 64. Wednesday, April 5, 2017. Pages 16581-16592
