        ^a all factors are based on the higher heating value of the fuel.
        ^b equivalent to 43 ppmv (15 percent O₂, dry basis) with an F factor of 8710 dscf/MMBtu.


    2.  Any electric power generating system boiler that operates with a combination of fuels shall comply with an adjusted emission factor calculated as follows:
        a.  if a combination of fuels is used normally, the emission factor from Paragraph D.1 of this Section shall be adjusted by the weighted average heat input of the fuels based on the ozone season average usage in 2000 and 2001, or another period if approved by the department;

        b.  if the boiler is normally fired with a primary fuel and a secondary fuel is available for back-up, the unit shall comply with the emission factor for the primary fuel while firing the primary fuel and with the emission factor for the secondary fuel while firing the secondary fuel.  In addition, the usage of the secondary fuel shall be limited to the ozone season average usage of the secondary fuel in 2000 and 2001, or another period if approved by the department; and

        c.  in either case, if the secondary fuel is less than 10 percent of the weighted average, the owner or operator may choose to comply with the unadjusted limit for the primary fuel.

    3.  For affected point sources in an electric power generating system, the emission factors from Subsection D of this Section shall apply as the mass of NOx emitted per unit of heat input (pound NOx per MMBtu), on a 30-day rolling average basis.  Alternatively, a facility may choose to comply with a ton per day or a pound per hour cap provided that monitoring is installed, calibrated, maintained, and operated to demonstrate compliance with the cap.  The cap for a facility or for multiple facilities under common control is calculated by adding the products of the factor from Paragraph D.1 of this Section and the average hourly heat input in MMBtu/hour (not to exceed any applicable permit limitations) based on the highest consecutive 30-day period during the ozone seasons of 2000 and 2001 for each affected point source as follows:

                           Equation D-1

     Cap (tpd) = 0.012  x  (Sum from i=1 to N of {(R_Ii  x  HI_i)})

where:

     HI_i  = the average hourly heat input based on the highest consecutive 30-day period during the ozone seasons of 2000 and 2001 of each point source (MMBtu/hour)

     i  = each point source included in the cap

     N  = the total number of point sources included in the cap

     R_Ii  = the limit for each point source from Subsection D of this Section (pound NOx/MMBtu)

      4. For all other affected point sources, the emission 
factors from Subsection D ofthis Section shall apply as the 
mass of NOx emitted per unit of heat input (pounds NOx per 
MMBtu or grams NOx per Hp-hour), on a 30-day rolling 
average basis. Alternatively, a facility may choose to comply 
with a cap as detailed in Paragraph D.3 of this Section, 
provided that a system, approved by the department, is 
installed, calibrated, maintained, and operated to 
demonstrate compliance.

    5.  If one affected point source discharges in part or in whole to another affected point source, the portion discharging into the second point source shall be treated as emanating from the second point source and shall be controlled to the same limit as that specified for the second point source, while the portion discharging directly to the atmosphere from the first point source shall be controlled to the limit of the first point source.  This term shall not include a combined cycle unit that discharges into a supplemental firing unit or other type of combustion equipment.  For this type of point source, the emissions shall be controlled as follows: 

        a.  for the turbines and/or engines, at the appropriate limits for the turbines and/or engines alone; and 

        b.  for the supplemental firing unit or other type of combustion equipment, at the appropriate limit for the supplemental firing or combustion equipment with the measured emission values adjusted for the emissions coming from the turbines and/or engines.

    6.  Where a common stack is used to collect vents from affected point sources or affected point sources and exempt point sources and monitoring and/or testing of individual units is not feasible, the department, upon application from the owner or operator, shall specify alternative methods to demonstrate compliance with the emission factors of this Subsection.
    
    7.  Any affected point source firing gaseous fuel that contains hydrogen and/or carbon monoxide may apply a multiplier, as calculated below, to the appropriate emission factor given in Paragraph D.1 of this Section.  The total hydrogen and/or carbon monoxide volume in the gaseous fuel stream is divided by the total gaseous fuel flow volume to determine the volume percent of hydrogen and/or carbon monoxide in the fuel supply.  In order to apply this multiplier, the owner or operator of the affected point source shall sample and analyze the fuel gas composition for hydrogen and/or carbon monoxide in accordance with Paragraph G.5 of this Section.

                             Equation D-2

              If (Vol. % H₂  +  Vol. % CO)  =  or  <  50

                                  Then 

                                   0.5  x  (Vol. % H₂  +  Vol. % CO)
        fuel multiplier  =  1  +  ----------------------------------
                                                 100

                                Otherwise

                         fuel multiplier  =  1.25

 
    8.  The owner or operator of a stationary gas turbine using a fuel that has an F factor different than 8710 dscf/MMBtu may adjust the allowable emission factor shown in Paragraph D.1 of this Section.  The adjustment is made by dividing the actual F factor (dscf/MMBtu) of the fuel by 8710 and multiplying the result by 0.16 to get the adjusted allowable emission factor.   The use of this option shall be detailed in the permit application or in the optional compliance plan described in Paragraph F.7 of this Section.

AQ305    §2201.D.9;LAd38;LA033.09;AQ305;LR36:0061(1/20/2010)
      9. On a day that is designated as on Ozone Action Day 
By the department, a facility shall not fire an affected point
Source with Number 6 fuel oil or perform testing of 
Emergency and training combustion units without prior 
approval of the administrative authority.  If a facility has 
received approval from the administrative authority for a 
plan to use Number 6 fuel oil, this is considered prior 
approval for purposes of this Paragraph.

E.  Alternative Plans

    1.  Facility-Wide Averaging Plan.  A facility-wide averaging plan is established in this Chapter for single affected facilities and multiple affected facilities that are owned or operated by the same entity.  For sources located within the Baton Rouge Nonattainment Area or the Region of Influence, an owner or operator of one or more affected facilities may use the facility-wide averaging plan as an alternative means of compliance with the emission factors from Subsection D of this Section.  A request for approval to use a facility-wide averaging plan, that includes the details of the plan, shall be submitted to the department either separately or with the permit application or in the optional compliance plan described in Paragraph F.7 of this Section.  A facility-wide averaging plan submitted under this provision shall be approved if the department determines that it will provide emission reductions equivalent to or more than that required by the emission factors in Subsection D of this Section and the plan establishes satisfactory means for determining initial and continuous compliance, including appropriate monitoring and recordkeeping requirements.  Approval of the alternative plans by the administrative authority does not necessarily indicate automatic approval by the administrator.

        a.  An owner or operator who elects to use a facility-wide averaging plan for compliance shall establish an emission factor for each applicable affected point source such that if each affected point source was operated at its averaging capacity, the cumulative emission factor in pounds NOx/MMBtu from all point sources in the averaging group would not exceed the facility-wide emission factor, as shown in Equation E-3. The equations below shall be used to calculate the cumulative emission rate and the facility-wide emission factor.

                    Equation E-1

     FL  =  Sum from i=1 to N of {(R_Ii  x  f_i)}


where:

                    Equation E-2


     f_i  =  (HI_i) /(Sum from i=1 to N of {HI_i})

 
                     Equation E-3


     (Sum from i=1 to N of {(R_ai x f_i)})  <=  FL 

where:

     f_i  = fraction of total system averaging capacity for point source i

     HI_i  = the averaging capacity of each point source (MMBtu/hour)

     i  = each point source in the averaging group

     N  = the total number of point sources in the averaging group

     R_ai  = the limit assigned by the owner to each point source in the averaging plan (pound NOx/MMBtu)

     R_Ii  = the limit for each point source from Subsection D of this Section (pound NOx/MMBtu)

     FL  = facility-wide emission factor (pound NOx/MMBtu) of all point sources included in the averaging plan


        b.  An owner or operator of an electric power generating system that chooses to use an averaging plan shall demonstrate compliance by either of the following methods:
            i.  operating such that each affected point source does not exceed its assigned individual limit in pound NOx/MMBtu on a 30-day rolling average basis; or
            ii.  complying with a cap as described in Paragraph D.3 of this Section, provided that a monitoring system is installed, calibrated, maintained, and operated to demonstrate compliance with the cap.

        c.  Owners or operators of all other affected point sources that choose to use an averaging plan shall demonstrate compliance by either of the following methods:
            i.  operating such that each affected point source does not exceed its assigned individual limit in pound NOx/MMBtu on a 30-day rolling average basis; or
            ii.  complying with a cap as described in Paragraph D.3 of this Section, provided a system, approved by the department, is installed, calibrated, maintained, and operated to demonstrate compliance with the cap.

AQ305    §2201.E.1.d;LAd38;LA033.09;AQ305;LR36:0061(1/20/2010)
         d. An owner or operator that chooses to use the 
provisions of Clause E.l.b.i or E.l.c.i of this Section to 
demonstrate compliance in an averaging plan shall include 
in the submitted plan a description of the actions that will be 
taken if any under-controlled unit is operated at more than 
10 percent above its averaging capacity (HI_i in Subparagraph 
E.l.a of this Section). Such actions may include a 
comparison of the total current emissions from all units in 
the averaging plan to the total emissions that would result if 
the units in the plan were operated in accordance with 
Subsection D of this Section, other reviews, reporting, 
and/or mitigation actions. If the department determines that 
the actions are not adequate to prevent an increase of 
emissions over the total emissions that would result if the 
units were operated in accordance with Subsection D of this 
Section, the department shall require that the averaging plan 
and/or the action plan be revised or shall disallow the use of 
the averaging plan.

        e.  The owner or operator of affected point sources complying with the requirements of this Subsection can include in the plan either all of the affected point sources at the facility or select only certain sources to be included.

AQ305    §2201.E.1.f;LAd38;LA033.09;AQ305;LR36:0061(1/20/2010)
         f. NOx reductions accomplished after 1997 through 
curtailments in capacity of a point source with a permit 
revision or by permanently shutting down the point source 
may be included in the averaging plan. In order to include a 
unit with curtailed capacity or that has been permanently 
shut down in the averaging plan, the old averaging capacity, 
determined from the average of the two ozone seasons prior 
to the capacity curtailment or shutdown, or such other two-year 
period as the department may approve, shall be used to 
calculate the unit's contribution to the term FL. The new 
averaging capacity, determined from the enforceable permit 
revision, shall be multiplied by the owner-assigned limit to 
calculate the contribution of the curtailed unit to the 
cumulative emission factor for the averaging group. For  
shut down source, the contribution to the cumulative 
emission factor shall be zero.

AQ305    §2201.E.1.g;LAd38;LA033.09;AQ305;LR36:0061(1/20/2010)
         g. NOx reductions from post 1997 modifications to 
exempted point sources, as defined in Subsection C of this 
Section, may be used in a facility-wide averaging plan. If a 
unit exempted in Subsection C of this Section is included in 
an averaging plan, the term R_Ii in Equation E-1 shall be 
established, in accordance with Subsection G of this Section, 
from a stack test or other determination of emissions 
approved by the department that was performed before the 
NOx reduction project was implemented, and the term R_ai 
shall be established from the owner-assigned emission factor 
in accordance with Subparagraph E.l.a of this Section. For 
the case of a point source exempted by Paragraph C.l5 of 
this Section, if the permit limits were established after 1997 
and were not required by a state or federal regulation, the 
source may be included in an averaging plan, with the term 
R_1i taken from Table D-1A or D-lB in Paragraph D.1 of this
Section.

        h.  Solely for the purpose of calculating the facility-wide emission factor, the allowable emission factor (pound NOx/MMBtu) for each affected stationary internal combustion engine is the applicable NOx emission factor from Subsection D of this Section (g/Hp-hour) divided by the product of the engine manufacturer's rated heat rate (expressed in Btu/Hp-hour) at the engine's Hp rating and 454 x 10^-6.

        i.  The owner or operator of affected point sources complying with the requirements of this Subsection in accordance with an emissions averaging plan shall carry out recordkeeping that includes, but is not limited to, a record of the data on which the determination of each point source's hourly, daily, or 30-day, as appropriate, compliance with the facility-wide averaging plan is based.

    2.  Trading Plan.  Trading is established in this Chapter as an alternate means of compliance with the emission factors from Subsection D of this Section.  Within the Baton Rouge Nonattainment Area and the Region of Influence, trading allowances, as defined in Subsection B of this Section, may be traded between affected facilities owned by different companies in a manner consistent with LAC 33:III.617.C.3.  The approval to use trading shall be requested in the permit application or in the optional compliance plan described in Paragraph F.7 of this Section.  A trading plan submitted under this provision shall be approved if the department determines that it will provide NOx emission reductions equivalent to or more than that required by the emission factors of Subsection D of this Section and the plan establishes satisfactory means for determining ongoing compliance, including appropriate monitoring and recordkeeping requirements.  Approval of trading plans by the administrative authority does not necessarily indicate automatic approval of the administrator.
