{"abstract":"The Environmental Protection Agency (the EPA or the Agency) has approved, subject to certain conditions, the request for a \"Small- scale Road Pilot Project on Private Land in Florida\" submitted by Mosaic Fertilizer, LLC in March 2022, and updated by the \"Revised Request for Approval of Use of Phosphogypsum in Small-scale Pilot Project\", submitted in August 2023. The Agency's review found that Mosaic's request is complete per the requirements of EPA's National Emissions Standards for Hazardous Air Pollutants under the Clean Air Act, and that the potential radiological risks from conducting the pilot project meet the regulatory requirement that the project is at least as protective of public health as maintaining the phosphogypsum in a stack. On October 9, 2024, the EPA issued a pending approval of the request and solicited public comments on the pending approval. While EPA received comments raising questions about the project, no comments were received which led EPA to change the results of its risk analyses for this proposed pilot project. This approval is only for the proposed pilot project, and EPA has placed conditions on the approval to make sure that the project remains within the scope of the application.","action":"Notice.","agencies":[{"raw_name":"ENVIRONMENTAL PROTECTION AGENCY","name":"Environmental Protection
