Final Rule: Mandatory Reporting of Greenhouse Gases
What Must Be Monitored?
If NOT using a CEMS, measure these parameters on a monthly basis...
~	Volume of gaseous feedstock (standard	~ Carbon content of solid feedstock
cubic feet [scf]) (with flow meter) (kg C per kg of feedstock)
~	Carbon content of gaseous feedstock	~ Annual urea production, if applicable
(kilogram [kg] C per kg of feedstock) (metric tons)
~	Molecular weight of the gaseous	~ CO2 from the steam reforming of a
feedstock (kg/kg-mole) hydrocarbon or the gasification of
solid and liquid raw material at the
ammonia manufacturing process unit
used to produce urea
~	Volume of liquid feedstock (gallons)	~ Carbon content of liquid feedstock
(with flow meter) (kg C per gallon of feedstock)
~	Mass of solid feedstock (kg)
(from company records and aggregated
on monthly basis)
If using a CEMS:
In addition to the monitoring requirements under 40 CFR subpart C for the
Tier 4 Calculation Methodology, measure these parameters...
~	Annual quantity of each type of
feedstock consumed for ammonia
manufacturing (scf of gaseous
feedstock, gallons of liquid
feedstock, and kg of solid feedstock)
