Final Emissions Factors for AP-42 Chapter 2, Section 2 - Sewage Sludge Incineration
Background
EPA's emission factor development team reviews and, if necessary, revises emissions factors for WebFIRE and AP-42. As part of this effort, EPA drafted new/revised emission factors for AP-42 Chapter 2, Section 2 - Sewage Sludge Incinerators. There was a 60 day public comment period that ended March 10, 2023 and no comments were received. Therefore, EPA is finalizing these emission factors. More information about emission factors that were reviewed but not drafted can be found at the bottom of this page.
