WebFIRE News

WebFIRE is EPA’s online emissions factor repository, retrieval, and development tool. The WebFIRE database contains EPA’s recommended emissions factors for criteria and hazardous air pollutants (HAP) for industrial and non-industrial processes. In addition, WebFIRE contains the individual data values used to develop the recommended factors and other data submitted to EPA by federal, state, tribal, and local agencies; consultants; and industries. For each recommended emissions factor and individual data value, WebFIRE contains descriptive information such as industry and source category type, control device information, the pollutants emitted, and supporting documentation.

WebFIRE includes data submitted to EPA from the Electronic Reporting Tool (ERT). Beginning January 1, 2012, industries are required to submit their source test data to EPA using the ERT application or the ERT approved spreadsheet. This information is shared with WebFIRE and is available to the public. More information about the ERT data is available on the Search WebFIRE page.

Information about updates, changes or enhancements to the system, and Frequently Asked Questions (FAQs) will be posted on this page.

If you are looking for a current list of Source Classification Codes (SCC), use the Emission Inventory System table found in the Appendix 6: Reporting Code database (MDB 7.75MB) on the Emission Inventory Information web site. This table was most recently updated in May 2012 and should not be used with the factor information found in WebFIRE at this time.

SCCs used with WebFIRE can be found on the Search WebFIRE page.
