We support specific electronic data reporting formats and you are required to report your data in a format consistent with these. Because electronic reporting technology continually changes, contact the Emission Factor and Inventory Group (EFIG) for the latest specific formats. You can find information on the current formats at the following Internet address: http:// [[Page 134]] www.epa.gov/ttn/chief.
