On November 7, 2024, the Board adopted amendments to keep Illinois’ hazardous waste regulations “identical in substance” to the federal regulations. The amendments reflect actions taken by the United States Environmental Protection Agency (USEPA) during the second half of calendar year 2023. During this timeframe, USEPA made technical revisions to correct or clarify provisions in the Generator Improvements, Pharmaceuticals, and Definition of Solid Waste rules under Subtitle C of the Resource Conservation and Recovery Act (RCRA). USEPA also made other minor corrections, clarifications, and updates to its hazardous waste regulations.
