In a letter dated July 16, 2012, EPA partially denied NGO petitions to regarding the insecticide chlorpyrifos. This September 12, 2007 petition was submitted jointly by the Natural Resources Defense Council and the Pesticide Action Network North America.  The petition requested that EPA revoke all tolerances and cancel all registrations for chlorpyrifos, pursuant to 21 U.S.C. section 346a(d) (section 408(d)) of the Federal Food Drug and Cosmetic Act. EPA states in the conclusion to its July 16th letter that

The Agency has carefully considered the six petition claims addressed in this response and has determined that none of these claims warrants revoking tolerances or canceling registrations for chlorpyrifos at this time.  This response does not constitute a final Agency action to petitioners’ request to revoke all tolerances for chlorpyrifos.

This response does, however, constitute EPA’s final action on the petition’s sole FIFRA issue, exporting hazard.
