3.  The owner or operator of any facility that is a source of air contaminants shall submit a complete emission inventory annually on forms obtained from the Division. The TAD is the form used to report the Emissions Inventory data to Oklahoma DEQ  DEQ Form #100-730 (TAD) contains the annual emissions inventory for a particular facility, as well as other relevant information such as the facility location and address, ownership details, operating hours and process rates, etc.  Redbud is the preferred method to report emissions inventories and provides a complete printed Turn Around Document for records 2012 Emissions Inventory Workshop 3

43. 2012 Emissions Inventory Workshop 43 "PM-10" means all particulate matter with an aerodynamic diameter of 10 micrometers or less (fine & coarse particle fractions combined)

44. 2012 Emissions Inventory Workshop 44 "PM-2.5" means particulate having an aerodynamic diameter equal to or less than 2.5 micrometers (i.e., the fine particle fraction)

47. 2012 Emissions Inventory Workshop 47 An emission factor is a representative value that attempts to relate the quantity of a pollutant released to the atmosphere with an activity associated with the release of that pollutant. Emissions = EF x Process Rate These factors are usually expressed as the weight of pollutant divided by a unit weight, volume, distance, or duration of the activity emitting the pollutant.

50.  Storage Tanks - use the Software TANKS  Landfills - use LANDGEM, a gas emissions model  Tank Flashing - Vasquez-Beggs equation  Glycol Dehydrator Reboiler - GRI-GLYCalc These are models with formulas using multiple variables. There is no single emission factor. 2012 Emissions Inventory Workshop 50
