On July 19, the Environmental Protection Agency denied a request by 27 individuals and groups to immediately suspend registrations for the insecticide chlothianidin.
The agency has since published an announcement in the Federal Register seeking public comment on its actions to deny the request.
Clothianidin is a neonicotinoid marketed under the names Clutch and Belay by Valent U.S.A. Corp., Walnut Creek, Calif.
Chlothianidin also is an ingredient in a handful of seed treatments, including Innovate and NipsIt Suite from Valent and Prosper and PonchoNotivo from Bayer CropScience, Research Triangle Park, N.C.
The EPA's actions stem from an "emergency citizen petition" submitted on March 20 by the Center for Food Safety and International Center for Technology Assessment on behalf of the individuals and non-governmental organizations.
They claimed that the insecticide received an unlawful conditional registration, according to the Federal Register notice.
The petition also cited the insecticide's "imminent hazard to pollinating insects."
In addition, the petition sought to stop the sale of misbranded chlothianidin products and to address Endangered Species Act consultation obligations over the insecticide.
The EPA addressed the initial request, since it was on an emergency basis.
The agency said it denied the emergency registration suspension because the evidence submitted did not demonstrate that continuing the insecticide's registration would cause an imminent, serious harm, according to the notice.
The EPA plans to address the remaining three issues after reviewing the public comments that are submitted.
Deadline to submit comments is Sept. 25.
