Public Hearing on EPA's proposed amendments to the Standards for Air Curtain Incinerators That Only Burn Wood Wastes, Yard Wastes and Clean Lumber; Provision for Commercial and Industrial Solid Waste Incineration Units: Temporary Use Incinerators and Air Curtain Incinerators Used in Disaster Recovery

The U.S. Environmental Protection Agency (EPA) will hold a virtual public hearing on April 6, 2026, to provide the public the opportunity to present comments and information regarding the Agency’s proposed amendments to the Standards for Air Curtain Incinerators That Only Burn Wood Wastes, Yard Wastes and Clean Lumber; Provision for Commercial and Industrial Solid Waste Incineration Units: Temporary Use Incinerators and Air Curtain Incinerators Used in Disaster Recovery.

On March 17, 2026, U.S. Environmental Protection Agency (EPA) issued a proposal to harmonize existing Clean Air Act (CAA) regulations and cut red tape for incinerators to help state, local, and Tribal governments prevent and respond to natural disasters.
EPA is proposing to consolidate the air curtain incinerator (ACI) requirements spread out across four CAA section 129 rules.
- EPA’s proposal, if finalized, will end decades of confusion surrounding CAA regulations and permits for incinerators, especially regarding when and how they can be utilized for debris cleanup following natural disasters.
- EPA is also proposing to make permanent the temporary-use provision for Commercial and Industrial Solid Waste Incineration (CISWI) during disaster response. EPA is responding directly to states’ request for more incinerators for emergency and disaster debris cleanup, including the request for the temporary use of CISWI units.
- EPA is taking public comment on revising the Other Solid Waste Incinerators (OSWI) definition of “municipal waste combustion unit” to remove the reference to “pyrolysis/combustion units.” Revising the definition would clarify that the OSWI rule does not regulate pyrolysis units used in advanced recycling operations.
  - Public comments received will help inform the development of a proposed rule on advanced recycling
