Documentation Supporting Proposed and Final Emissions Factors
Supporting Documents for Proposed and Final Actions
As performance data is collected in WebFIRE, emissions factors might be created or revised and proposed. If an emissions factor is proposed, there will be a 60 day public comment period. After the public comment period, and comments are reviewed, the proposed or reviewed/revised emissions factor might be finalized and posted in WebFIRE. The supporting documentation for the emissions factor will be available through this page.
