EPA Decision Documents for Emergency Exemption Requests for Use Of Grignard Pure

On Thursday, January 14, 2021, the U.S. Environmental Protection Agency (EPA) issued an emergency exemption for an antiviral air treatment, Grignard Pure, to be used in certain indoor spaces where social distancing can be challenging. This exemption has been granted to Georgia and Tennessee. After carefully reviewing safety and efficacy data, EPA has determined the product will provide another tool to assist Americans during the current public health emergency.

On Thursday, July 1, 2021, EPA issued emergency exemptions to Maryland, Nevada, Pennsylvania, and Texas for Grignard Pure. EPA also revised the terms of use for Grignard Pure for all emergency exemptions. After conducting a comprehensive review of new efficacy data, EPA determined that Grignard Pure is effective in reducing SARS-CoV-2 in the air at a lower use rate than was previously approved.

These documents explain EPA’s decision to approve these Section 18 requests and provide information on the proper use of these products.
