the total tons of clinker produced in that kiln during the same 30-day
operating period, using the following equation:
[GRAPHIC] [TIFF OMITTED] TR03SE14.003

Where:

E[D] = 30 kiln operating day average emission rate of
NOX, lb/ton of clinker;
C[i] = Concentration of NOX for hour i, ppm;
Q[i] = Volumetric flow rate of effluent gas for hour i, where C[i]
and Q[i] are on the same basis (either wet or dry), scf/hr;
P[i] = Total kiln clinker produced during production hour i, ton/hr;
k = Conversion factor, 1.194 x 10<-7> for NOX; and

operator shall submit to EPA for review a protocol (``Optimization
Protocol'') for optimizing the ammonia injection system, including
optimization of the operational parameters resulting in the
minimization of emissions of NOX to the greatest extent
practicable without violating any limits. The Protocol shall

optimize the facility processes to minimize emissions from the kiln
and adjust ammonia injection system operating parameters, and shall
include the following:
    a. The following measures to optimize the facility's processes
to reduce NOx emissions in conjunction with the ammonia injection
system:
    i. Adjustment of the balance between fuel supplied to the
existing riser duct burner and the existing calciner burners to
improve overall combustion within the calciner while maintaining
product quality;
    ii. Adjustments to the calciner combustion to ensure complete
fuel burning, which will help to both reduce CO and improve NOx
levels by, at a minimum:
    1. Adjusting fuel fineness to improve the degree of combustion
completed in the calciner; and
    2. Adjusting the proportions of primary, secondary and tertiary
air supplied to the kiln system while maintaining product quality;
and
    iii. Adjustments to the raw mix chemical and physical properties
using onsite raw materials to improve kiln stability and maintain
product quality, including but not limited to, fineness of the raw
mix. As part of this optimization measure, the owner/operator shall
take additional measurements using existing monitoring equipment at
relevant process locations to evaluate the impact of raw mix
refinements.
    b. The range of reagent injection rates (as a molar ratio of the
average pollutant concentration);
    c. Sampling and testing programs that will be undertaken during
the initial reagent injection rate period;
    d. A plan to increase the reagent injection rate to identify the

and associated sampling and testing programs for each increase in
the reagent rate. The owner/operator shall test, at a minimum, for
the ammonia injection system at molar ratios of 0.75, 1.0, and 1.20.
If data collected at the highest molar ratio indicates decreasing
lb/ton emissions, the owner/operator shall continue to test the
ammonia injection system by increasing the molar ratio by increments
of 0.10 until either the lb/ton emission data indicates no
significant decrease from the previous increment, or adverse effects
are observed (e.g., ammonia slip emissions above 10 ppm, presence of
a secondary particulate plume, impaired product, impaired kiln
operations).
    e. The factors that will determine the optimum reagent injection
rates and pollutant emission reductions (including maintenance of
Kiln, productivity, and product quality); and
    f. Evaluation of any observed synergistic effects on Kiln
emissions, Kiln operation, reagent slippage, or product quality from
the ammonia injection system.
    11. As part of the Optimization Protocol, the owner/operator
shall submit to EPA a schedule for optimizing each the ammonia
injection system parameters identified in Item 10 of this appendix.
The schedule shall indicate the total duration of the Optimization
period, and must optimize each identified parameter for the
following minimum amounts of time:

------------------------------------------------------------------------

------------------------------------------------------------------------

    12. Within 60 days following the termination of the Optimization
Period(s), the owner/operator shall submit to EPA for review an
Optimization Report demonstrating conformance with the Optimization
Protocol for the ammonia injection system and establishing the
optimized operating parameters for the facility processes and the
ammonia injection system determined under the Optimization Protocol,
including optimized injection rates for all reagents. The owner/
operator may take into account energy, environmental, and economic
impacts and other costs in proposing the optimized state of the
ammonia injection system, including the injection rates of reagents,
and the operating parameters for the facility processes. The owner/
operator may also include in the Optimization Report a discussion of
any problems encountered during the Optimization Period, and how
that problem may impact the potential emission reductions (e.g. the
quantity of reagent slip at varying injection rates and/or the
possible observance of a detached plume above the Stack).
    13. Optimization Targets: Except as otherwise provided in this
Item and in Item 14 of this appendix, the ammonia injection system
shall be deemed to be optimized if the Optimization Report
demonstrates that the ammonia injection system during periods of
normal operation has achieved emission reductions consistent with
its maximum design stoichiometric rate identified in the Design
Report.
    14. Notwithstanding the provisions of Item 13 of this appendix,
the ammonia injection system may be deemed to be optimized at a
lower rate of emission reductions than that identified in Item 13 of
this appendix if the Optimization Report demonstrates that, during
periods of normal operation, a lower rate of emission reductions
cannot be sustained after all parameters and injection rates are
optimized during the Optimization Period without creating a
meaningful risk of impairing product quality, impairing Kiln system
reliability, impairing compliance with a maximum ammonia slip
emissions limit of 10 ppm or other permitted levels, or forming a
detached plume.
    15. During the Optimization Period, the owner/operator, to the
extent practicable and applicable, shall operate the ammonia
injection system in a manner consistent with good air pollution
control practice consistent with 40 CFR 60.11(d). The owner/operator
will adjust its optimization of the ammonia injection system as may
be necessary to avoid, mitigate or abate an identifiable non-
compliance with an emission limitation or standard for pollutants
other than NOx. In the event the owner/operator determines, prior to
the expiration of the Optimization Period, that its ability to
optimize the ammonia injection system will be affected by potential
impairments to product quality, kiln system reliability or increased
emissions of other pollutants, then the owner/operator shall
promptly advise EPA of this determination, and include these
considerations as part of its recommendation in its Optimization
Report.

V. Demonstration Period

    16. The Demonstration Period shall commence within 7 days after
the owner/operator's receipt of final comments from EPA on the
Optimization Report. During the Demonstration Period, the owner/
operator shall operate the ammonia injection system for a period of
270 Operating Days consistent with the optimized operations of the
Facility and the ammonia injection system as contained in the
Optimization Report. This 270 Operating Day Demonstration Period may
be shortened or lengthened as provided for in Items 17 and 18 of
this appendix.
    17. If Kiln Operation is disrupted by excessive unplanned
outages, or excessive Startups and Shutdowns during the
Demonstration Period, or if the Kiln temporarily ceases operation
for business or technical reasons, the owner/operator may advise EPA
that it is necessary to temporarily extend the Demonstration Period.
Data gathered during periods of disruption may not be used to
determine an emission limitation.
    18. If evidence arises during the Demonstration Period that
product quality, kiln system reliability, or emission compliance
with an emission limitation or standard is impaired by reason of
longer term operation of the ammonia injection system in a manner
consistent with the parameters identified in the Optimization
Report, then the owner/operator may, upon notice to EPA, temporarily
modify the manner of operation of the facility process or the
ammonia injection system to mitigate the effects and, if necessary,
notify EPA that the owner/operator will suspend or extend the

Demonstration Period for further technical evaluation of the effects
of a process optimization or permanently modify the manner of
operation of the ammonia injection system to mitigate the effects.
    19. During the Demonstration Period, the owner/operator shall
collect the same data as required in Item 8 of this appendix. The
Demonstration Report shall include the data collected as required in
this Item.
    20. Within 60 Days following completion of the Demonstration
Period for the ammonia injection system, the owner/operator shall
submit a Demonstration Report to EPA, based upon and including all
of the data collected during the Demonstration Period including data
from Startup, Shutdown and Malfunction events, that identifies a
proposed 30-kiln operating day emission limit for NOX.
The 30-kiln operating day emission limit for NOX shall be
based upon an analysis of CEMS data and clinker production data
collected during the Demonstration Period, while the process and
ammonia injection system parameters were optimized in determining
the proposed final Emission Limit(s) achievable for the Facility.
Total pounds of an affected pollutant emitted during an individual
Operating Day will be calculated from collected CEMS data for that
Day. Hours or Days when there is no Kiln Operation may be excluded
from the analyses. However, the owner/operator shall provide an
explanation in the Demonstration Report(s) for any data excluded
from the analyses. In any event, the owner/operator shall include
all data required to be collected during the Demonstration Period in
the Final Demonstration Report(s).
    21. The owner/operator shall propose a 30-kiln operating day
emission limit for NOx in the Demonstration Report(s) as provided in
Item 20 of this appendix. This 30-kiln operating day emission limit
shall be calculated in accordance with the following formula:

X = [mu] + 1.65[sigma]

Where:

X = 30-Day Rolling Average Emission Limit (lb/Ton of clinker);
[mu] = arithmetic mean of all of the 30-Day rolling averages;
[sigma] = standard deviation of all of the 30-Day rolling averages,
as calculated in the following manner:
[GRAPHIC] [TIFF OMITTED] TR03SE14.004

Where:

N = The total number of rolling 30-kiln operating day emission
rates;

xi = Each rolling 30-kiln operating day emission rate;
x  = The mean value of all of the rolling 30-kiln operating day
emission rates.

    22. Supporting data required to be submitted under this appendix
may contain information relative to kiln operation and production
that the owner/operator may consider to be proprietary. In such a
situation, the owner/operator may submit the information to EPA as
CBI, subject to the provisions of 40 CFR part 2.

    m. An explanation of any gaps in the data or missing data; and
    n. Amount of oxygen generated and introduced into the Kiln (lb/
day).
    9. The owner/operator shall submit the data to EPA in an
electronic format and shall explain the reasons for any data not
collected for each of the parameters. The owner/operator shall
report all data in a format consistent with and able to be
manipulated by Microsoft Excel.
    10. Prior to commencement of the Optimization Period, the owner/
operator shall submit to EPA for review a protocol (``Optimization
Protocol'') for optimizing the ammonia injection system, including
optimization of the operational parameters resulting in the
minimization of emissions of NOX to the greatest extent
practicable without violating any limits. The Protocol shall
describe procedures to be used during the Optimization Period to
optimize the facility processes to minimize emissions from the kiln
and adjust ammonia injection system operating parameters, and shall
include the following:
    a. The range of reagent injection rates (as a molar ratio of the
average pollutant concentration);
    b. Sampling and testing programs that will be undertaken during
the initial reagent injection rate period;
    c. A plan to increase the reagent injection rate to identify the
injection rates with the maximum emission reduction effectiveness
and associated sampling and testing programs for each increase in
the reagent rate. The owner/operator shall test, at a minimum, for
the ammonia injection system at three molar ratios of 0.75, 1.0, and
1.20;
    d. The factors that will determine the optimum reagent injection
rates and pollutant emission reductions (including maintenance of
Kiln, productivity, and product quality); and
    e. Evaluation of any observed synergistic effects on Kiln
emissions, Kiln operation, reagent slippage, or product quality from
the ammonia injection system.
    f. Any additional facility processes that the owner/operator
determines may reduce NOX emissions in conjunction with
the ammonia injection system.
    11. As part of the Optimization Protocol, the owner/operator
shall submit to EPA a schedule for optimizing each of the ammonia
injection system parameters identified in Item 10 of this appendix.
The schedule shall indicate the total duration of the Optimization
period, and must optimize each identified parameter for the
following minimum amounts of time:

------------------------------------------------------------------------
                                                             Minimum
                                                           optimization

                                                            (operating
                                                              days)
------------------------------------------------------------------------
Setup of SNCR, initial operation of reagent injection,               60
 and calibration.......................................
------------------------------------------------------------------------

    12. Within 60 Days following the termination of the Optimization
Period(s), the owner/operator shall submit to EPA for review an
Optimization Report demonstrating conformance with the Optimization
Protocol for the ammonia injection system and establishing the
optimized operating parameters for the facility processes and the
ammonia injection system determined under the Optimization Protocol,
including optimized injection rates for all reagents. The owner/
operator may take into account energy, environmental, and economic
impacts and other costs in proposing the optimized state of the
ammonia injection system, including the injection rates of reagents,
and the operating parameters for the facility processes. The owner/
operator may also include in the Optimization Report a discussion of
any problems encountered during the Optimization Period, and how
that problem may impact the potential emission reductions (e.g. the
quantity of reagent slip at varying injection rates and/or the
possible observance of a detached plume above the Stack).
    13. Optimization Targets: Except as otherwise provided in this
Item and in Item 14 of this appendix, the ammonia injection system
shall be deemed to be optimized if the Optimization Report
demonstrates that the ammonia injection system during periods of
normal operation has achieved emission reductions consistent with
its maximum design stoichiometric rate identified in the Design
Report approved pursuant to Item 3 of this appendix.
    14. Notwithstanding the provisions of Item 13 of this appendix,
the ammonia injection system may be deemed to be optimized at a
lower rate of emission reductions than that identified in Item 13 of
this appendix if the Optimization Report demonstrates that, during
periods of normal operation, a lower rate of emission reductions
cannot be sustained after all parameters and injection rates are
optimized during the Optimization Period without creating a
meaningful risk of impairing product quality, impairing Kiln system
reliability, impairing compliance with a maximum ammonia slip
emissions limit of 10 ppm or other permitted levels, or forming a
detached plume.
    15. During the Optimization Period, the owner/operator, to the
extent practicable and applicable, shall operate the ammonia
injection system in a manner consistent with good air pollution
control practice consistent with 40 CFR 60.11(d). The owner/operator
will adjust its optimization of the ammonia injection system as may
be necessary to avoid, mitigate or abate an identifiable non-
compliance with an emission limitation or standard for pollutants
other than NOX. In the event the owner/operator
determines, prior to the expiration of the Optimization Period, that
its ability to optimize the ammonia injection system will be
affected by potential impairments to product quality, kiln system
reliability or increased emissions of other pollutants, then the
owner/operator shall promptly advise EPA of this determination, and
include these considerations as part of its recommendation in its
Optimization Report.

V. Demonstration Period

    16. The Demonstration Period shall commence within 7 days after
the owner/operator's receipt of the final comments from EPA on the
Optimization Report. During the Demonstration Period, the owner/
operator shall operate the ammonia injection system for a period of
360 Operating Days consistent with the optimized operations of the
Facility and the ammonia injection system as contained in the
Optimization Report. This 360 Operating Day Demonstration Period may
be shortened or lengthened as provided for in Items 17 and 18 of
this appendix.
    17. If Kiln Operation is disrupted by excessive unplanned
outages, or excessive Startups and Shutdowns during the
Demonstration Period, or if the Kiln temporarily ceases operation
for business or technical reasons, the owner/operator may advise EPA
that it is necessary to temporarily extend the Demonstration Period.
Data gathered during periods of disruption may not be used to
determine an emission limitation.
    18. If evidence arises during the Demonstration Period that
product quality, kiln system reliability, or emission compliance
with an emission limitation or standard is impaired by reason of
longer term operation of the ammonia injection system in a manner
consistent with the parameters identified in the Optimization
Report, then the owner/operator may, upon notice to EPA, temporarily
modify the manner of operation of the facility process or the
ammonia injection system to mitigate the effects and, if necessary,
notify EPA that the owner/operator will suspend or extend the
Demonstration Period for further technical evaluation of the effects
of a process optimization or permanently modify the manner of
operation of the ammonia injection system to mitigate the effects.
    19. During the Demonstration Period, the owner/operator shall
collect the same data as required in Item 8 of this appendix. The
Demonstration Report shall include the data collected as required in
this Item.
    20. Within 60 Days following completion of the Demonstration
Period for the ammonia injection system, the owner/operator shall
submit a Demonstration Report to EPA, based upon and including all
of the data collected during the Demonstration Period including data
from Startup, Shutdown and Malfunction events, that identifies a
proposed rolling 12-month emission limit for NOX. The
rolling 12-month emission limit for NOX shall be based
upon an analysis of

CEMS data and lime production data collected during the
Demonstration Period, while the process and ammonia injection system
parameters were optimized in determining the proposed Emission
Limit(s) achievable for the Facility. However, the owner/operator
shall provide an explanation in the Demonstration Report(s) for any
data excluded from the analyses. In any event, the owner/operator
shall include all data required to be collected during the
Demonstration Period in the Final Demonstration Report(s).
    21. The owner/operator shall propose a rolling 12-month emission
limit for NOX in the Demonstration Report(s) as provided
in Item 20 of this appendix. This rolling 12-month limit shall be
calculated in accordance with the following formula:

X = [mu] + 1.65[sigma]

Where:

X = Rolling 12-month Average Emission Limit (lb/Ton of lime
product);
[mu] = arithmetic mean of all of the Rolling 12-month averages;
[sigma] = standard deviation of all of the rolling 12-month
averages, as calculated in the following manner:
[GRAPHIC] [TIFF OMITTED] TR03SE14.005

Where:

N = The total number of rolling 12-month emission rates;
xi = Each rolling 12-month emission rate;
x = The mean value of all of the rolling 12-month emission rates.
    22. Supporting data required to be submitted under this Appendix
may contain information relative to kiln operation and production
that the owner/operator may consider to be proprietary. In such a
situation, the owner/operator may submit the information to EPA as
CBI, subject to the provisions of 40 CFR part 2.
