Detailed Emission Factor Search

Enter one or more search criteria then "Submit Search." Source Classification Codes should be entered without dashes. Description levels 1 through 4 should be selected in order. Be careful about limiting your search too much with descriptions, control codes and pollutants. Keep your search criteria broad to begin with and narrow it as you review the results. The information links will explain the specifics for each search attribute. For more information about the Detailed Search, see the Help Information.
