3. What is a Turn Around Document? (“TAD”) • 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

23. Emission Unit Status Operating–this emission unit operated all or part of the calendar year (Active at anytime during the year). Temporarily Shutdown–thisemission unit did not operate at all during the calendar year, but may restart at sometime in the future (no emissions during the calendar year). Permanently Shutdown–selectthis status if an emission unit has been removed, removed from service, or is permanently shutdown (no emissions during the calendar year). 2012 Emissions Inventory Workshop

35. Multiple ProcessesWithin an Emissions Unit • TANKS: if over 5 tons of emissions – separate breathing, working and flashing losses. Under 5 tons of emissions, losses can be combined using SCC 40400311 • ANY EQUIPMENT that utilizes different process material (coal, wood, natural gas) 2012 Emissions Inventory Workshop

42. Particulate Matter Two Categories – Dependent on Particle Size PM-10 and PM-2.5 2012 Emissions Inventory Workshop

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

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

46. Emission Factors 2012 Emissions Inventory Workshop

47. What Is An Emission Factor? 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. 2012 Emissions Inventory Workshop

50. Is an Emission Factor Needed? • 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
