{"abstract":"The Environmental Protection Agency (the EPA or the Agency) seeks public comment on its pending approval of a 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 subject to certain conditions. The EPA is soliciting public comments on the pending approval.","action":"Notice of availability.","agencies":[{"raw_name":"ENVIRONMENTAL PROTECTION AGENCY","name":"Environmental Protection
