On April 16, 2026, for public comment, the Board proposed amendments to keep Illinois’ hazardous waste regulations “identical in substance” to the federal regulations. The proposal reflects actions taken by the United States Environmental Protection Agency (USEPA) during the second half of calendar year 2024. During this timeframe, among other things, USEPA (1) amended the hazardous waste manifest regulations to increase utility of the electronic manifest or “e-Manifest” system, (2) established alternative standards for specified ignitable spent refrigerants being recycled for reuse, and (3) adopted technical corrections to its 2016 Hazardous Waste Generator Improvements Rule and 2019 Hazardous Waste Pharmaceuticals Rule.
