  review of the Standards of Performance for New Stationary Sources and Emissions Guidelines for 
Existing Sources: Other Solid Waste Incineration (OSWI) Units, which includes certain very small 
municipal waste combustion (VSMWC) and institutional waste in cineration (IWI) units. In the same 
action, the EPA proposed to modify the OSWI definition of "municipal waste combustion unit," 
effectively removing pyrolysis/combustion units from the definition. In this action, the EPA is 
withdrawing that proposed modif ication.  
DATES: As of 5 June 2023, EPA withdraws the proposed definition "Municipal waste combustion unit" 
in Sec. 60.2977, published at 85 FR 54178 , on 31 August 2020.  
This withdrawal of proposed provision and the proposed rule notified as G/TBT/N/USA/1645  are 
identified by Docket Number EPA -HQ-OAR-2003-0156. The Docket Folder is availabl e on 
Regulations.gov at https://www.regulations.gov/docket/EPA -HQ-OAR-2003-0156/document  and 
provides access to primary and supporting documents as well as comments received. Documents
