2060-AW94 202510 The Regulatory Plan and the Unified Agenda of Federal Regulatory and Deregulatory Actions 2060 Office of Air and Radiation OAR 2000 Environmental Protection Agency EPA Federal Plan Requirements for Other Solid Waste Incineration Units Constructed on or Before August 31, 2020, and Have Not Been Modified or Reconstructed After August 29, 2025

On June 30, 2025, the EPA promulgated the final Standards of Performance for New Stationary Sources and Emission Guidelines for Existing Sources: Other Solid Waste Incineration (OSWI) Units Review (90 FR 27910). The Clean Air Act (CAA) directs states with OSWI units subject to the Emission Guidelines to submit plans to the EPA that implement and enforce the Emission Guidelines. The Emission Guidelines contain model rule language that states can use for implementation. If a state with existing OSWI units does not submit an approvable plan by June 30, 2026, the EPA has a statutory requirement to develop, implement, and enforce a Federal plan for OSWI units in the state. This action will propose and promulgate a Federal plan to implement Emission Guidelines for OSWI units located in states and Indian country without effective state or Tribal plans.
