EPA is Removing 72 Inert Ingredients Previously Approved for Use in Pesticide Products
On October 22, 2014, EPA published for comment a proposal to remove from EPA’s list of inert ingredients approved for use in pesticide products 72 chemical substances that are no longer being used as inert ingredients in pesticide products. (79 FR 63120) In response to EPA’s request for comments, no specific information regarding those 72 chemical substances or any products that may include them was provided to EPA, indicating that these chemical substances are not being used in currently approved pesticide product formulations. Therefore, as of December 14, 2016, (81 FR 90356) EPA decided to remove all 72 from the inert ingredient list. A list of the 72 inert ingredients can be found here.
Removal of a chemical substance from the approved inert ingredient listing does not, in and of itself, restrict the use of the chemical substance in a pesticide product, instead it changes the way an application is processed. Once removed, the chemical substance would be considered a “new” inert ingredient. Any inert ingredient that is not on the approved list must be approved by EPA before registration for a formulation containing that chemical substance as an inert ingredient. EPA approval can be obtained by submitting a request, along with relevant data including, among other things, studies to evaluate potential carcinogenicity, adverse reproductive effects, developmental toxicity, genotoxicity, as well as environmental effects associated with any chemical substance that is persistent or bioaccumulative. Further, adding the chemical substance to the list of approved inert ingredients would also require payment of a fee in accordance with FIFRA Section 33, 7 U.S.C. 136w-8.
