What Must Be Monitored for Each Soda Ash Manufacturing Line?

              If NOT using a CEMS, measure these parameters...

Site-specific emission factor method:
  D   Process vent flow rate from mine water
      stripper/evaporator during annual
      performance test (pounds/hour)

  D   Stack gas volumetric flow rate per minute
      (dscfm)
    Hourly carbon dioxide (CO2)
    concentration (percent CO2)
     CO2 mass emission rate
     (metric tons/hour)
Alternative calculation method:
  D   Monthly inorganic carbon content in trona
      input by daily measurement
      (percent by weight)

  D   Monthly inorganic carbon content in soda
      ash output by daily measurement
      (percent by weight)


Other parameters:
D    Monthly mass of trona input (tons)
D    Monthly mass of soda ash output (tons)
 D   Monthly consumption of trona or liquid
      alkaline feedstock (metric tons)
D    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...
D
Monthly consumption of trona or liquid
alkaline feedstock (metric tons)

D
Monthly production of soda ash (tons)
