Other - Blowdown Vent Stacks
- Q555. Is 98.233.i blowdown vent stacks applicable to pipeline blowdowns (if occuring at a subpart W facility such as a wellpad)?
- Q556. There is an error in the calculation methodology for blowdown vent stacks (Eq. W-14) because volumetric emissions of natural gas at standard conditions cannot be converted directly to GHG mass emissions using the method in 98.233(v).
- Q557. For blowdown vent stacks, does the 40 CFR 98.233(i) reference to a volume of less than 50 cubic feet refer to a gas volume or a physical container volume?
- Q558. May average blowdown volumes be used when reporting the blowdown vent stacks emission source?
- Q559. If the blowdown gas from a facility or compressor at an onshore petroleum and natural gas production facility is routed to a flare, do the emissions to the flare have to be reported?
