WebFIRE

WebFIRE is the EPA's online database that contains emissions factors for criteria and hazardous air pollutants (HAP) for industrial and non-industrial processes and multiple reports submitted to the EPA using the Compliance and Emissions Data Reporting Interface (CEDRI) in response to regulatory requirements under Parts 60 and 63 of Title 40 of the U.S. Code of Federal Regulations (CFR). WebFIRE also allows you to prepare batch downloads of WebFIRE emissions and facility information. Please note that the batch downloads includes formula-based emission factors that are not retrieved in the WebFIRE emission factor search.
