Lime Manufacturing Monitoring Checklist
Final Rule: Mandatory Reporting of Greenhouse Gases

What Must Be Monitored for Kilns?

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

For determining the monthly emission factor for each type of lime produced:
                               United States
                               Environmental Protection
                               Agency
       Calcium oxide content for each lime
       type (metric tons CaO/metric ton lime),
       analyzed monthly.
Magnesium oxide content for each lime
type (metric tons MgO/metric ton lime),
analyzed monthly.
For determining the monthly emission factor for each type of byproduct/waste sold (including lime
kiln dust):
       Calcium oxide content for each solid
       lime byproduct/waste type
       (metric tons CaO/metric ton lime),
       analyzed monthly.
Magnesium oxide content for each solid
lime byproduct/waste type
(metric tons MgO/metric ton lime),
analyzed monthly.
For determining annual CO2 emissions from each type of byproduct/waste that is not sold
(including lime kiln dust and scrubber sludge):
       Calcium oxide content for each unsold
       lime byproduct/waste type
       (metric tons CaO/metric ton lime),
       analyzed annually.

       Magnesium oxide content for each
       unsold lime byproduct/waste type
       (metric tons MgO/metric ton lime),
       analyzed annually.
For determining annual CO2 process emissions for all kilns:
Annual weight or mass of unsold
byproducts/wastes for each lime type
(tons).
       Monthly weight or mass of each lime
       type produced (tons)
Monthly weight or mass of
byproducts/waste sold (such as lime kiln
dust) for each lime type (tons)

-------
For all kilns combined (i.e., for the whole facility):
       Monthly amount of lime product sold,
       by type (tons)

       Monthly amount of lime
       byproduct/waste sold, by type (tons)

       Annual amount of CO2 captured for use
       in the onsite process (if applicable)

                                  IfusingaCEMS:
 In addition to the monitoring requirements under 40 CFR subpart C for the
  Tier 4 Calculation Methodology, measure these parameters for each kiln...
       Annual amount of lime product sold, by
       type (tons)

       Annual amount of lime byproduct/waste
       sold, by type (tons)

       Annual amount of lime byproduct/waste
       not sold, by type (tons)
Annual amount of lime product not sold,
by type (tons)

Beginning and end of year inventories
for each lime product

Beginning and end of year inventories
for lime byproducts/wastes
