What Must Be Monitored for Each Soda Ash Manufacturing Line?
If NOT using a CEMS, measure these parameters...
Site-specific emission factor method:
l_l Hourly carbon dioxide (CO2)
concentration (percent CO2)
Trona Input method (Eq. CC-1):
Monthly inorganic carbon content in trona input by
weekly composite analysis (percent by weight)
Monthly mass of trona input
(tons)
Soda Ash Output method (Eq. CC-2):
Monthly inorganic carbon content in soda ash
~ output by weekly composite analysis
(percent by weight)
Other parameters:
Monthly mass of soda ash
output (tons)
Monthly consumption of trona or liquid alkaline
feedstock (metric tons)
Monthly production of soda ash
(tons)
If using a CEMS:
In addition to the monitoring requirements under 40 CFR subpart C for the
Tier 4 Calculation Methodology, measure these parameters...
Monthly consumption of trona or liquid
alkaline feedstock (metric tons)
~ Monthly production of soda ash (tons)
