EPA is rescinding the interim final rule (IFR) titled "Commercial and Industrial Solid Waste Incineration Units: Temporary-Use Incinerators and Air Curtain Incinerators Used in Disaster Recovery." The IFR added temporary-use provisions that excluded certain commercial and industrial solid waste incineration (CISWI) units from otherwise applicable requirements when used on a temporary basis to combust non-hazardous debris in specified emergency or disaster circumstances. The EPA is rescinding those provisions and intends to address the same subject matter through notice-and-comment rulemaking culminating in a final rule. This rule is effective on 19 March 2026.
