• A unique name or ID number for the vent stack (98.236(c)(9)(iii))
• Annual CO₂ emissions from venting gas directly to the atmosphere (98.236(c)(9)(i))
• Annual CH₄ emissions from venting gas directly to the atmosphere (98.236(c)(9)(i))
• Annual CO₂ emissions from flaring process gas (98.236(c)(9)(ii))
• Annual CH₄ emissions from flaring process gas (98.236(c)(9)(ii))
• Annual N₂O emissions from flaring process gas (98.236(c)(9)(ii))

 

Total Emissions

The total emissions roll-up at the top of the sheet reflects the sum of the CO₂ equivalents of each gas emission reported for the source type.  These summations are reflected and aggregated on the Introduction tab.
