Overview
- EPA records document a two-day search at the Roseland facility in mid-November involving EPA Criminal Investigation Division agents with FBI and Louisiana State Police present.
- Cleanup operations were paused for about three hours on Nov. 18 during the search, and federal and state agents departed after two days as EPA oversight of the site continued.
- Officials confirmed a federal criminal investigation related to the August explosion and fire, and no criminal charges have been publicly reported to date.
- The search became public through an EPA emergency response report posted in mid-December, and agencies have not disclosed what investigators sought.
- Civil enforcement remains active through a Nov. 5 federal lawsuit by EPA and Louisiana authorities and an EPA compliance order following an October inspection that cited hazardous waste handling issues and set a 60‑day timetable for fixes.
