21. 4/14/04 NEW COMMENT VI S19 Condition 1240, PartI.16a

Condition 1240, Part I.16.a shouldbe modified as shown below todelete language referring to sourcetesting to demonstrate compliancewith the NOx and CO limits ofRegulation 9, Rule 10 and toincrease the source test reportingperiod from 30 to 45 days:

16a. The permit holder shallperform a source test at S19,Vacuum Heater, every 6 months todetermine compliance with the NOxand CO standards in Regulation 9,Rule 10 the NOx limit in part I.8 ofthis condition, and the CO limit inparts I.5b and I.5c of this condition.The source test shall be performed ata minimum of 85% of the maximumcapacity of 40 MMBtu/hr (34 to 40MMBtu/hr). All source testing shallbe done in accordance with theDistrict's Manual of Procedures. Thefacility shall receive approval fromthe District's Source Test Managerfor installation of test ports andsource testing procedures. Theresults shall be delivered to theDistrict no later than 30 45 daysfrom the date of the source test.(Regulation 9-10-301, 9-10-305,Cumulative Increase, BACT)

This permit condition language isredundant with Condition 20617, Part7.a.2. The source test submittalrequirement of 30 days for Condition1240, Part I.16a conflicts with the 45-day submittal period for Condition20617, Part 7.a.2.

In addition, the 45-day period allowsthe source test contractor one month toprepare the report and two weeks forValero to review the report.



Line#




22. 4/14/04 NEW COMMENT VI S19 Condition 1240, PartI.16b

Modify Condition 1240, Part I.16bto increase the source test reportingperiod from 30 to 45 days.

Part I.16b conflicts with the 45-daysubmittal period for Condition 20617,Part 7.a.2. The 45-day period allowsthe source test contractor one month toprepare the report and two weeks forValero to review the report.

23. 4/14/04

8/11/03

No. VI S19 1240.I.16a Delete “a minimum of 85% of themaximum capacity of 40 MMBtu/hr(34 to 40 MMBtu/hr)”; and replacewith “highest duty possible for theprevailing process conditions”

It is very difficult to run this source atthe upper end of its limit. The normaloperating duty for S19 is approximately30 MMBTU/hr. It will be difficult toadjust the operating parameters for thisdevice to reach the upper duty range forfrequent (semi-annual) source tests.

24. 4/14/04

NEW VI

IV-P, AP

S24A31

Condition 1240.II.58b Modify the permit to include aprovision to allow for an averagingperiod for the temperature limit.Add the following language asCondition 1240, Part II.58b:

“For S-24, the minimum combustionzone temperature shall be 1,100 F,averaged over any consecutive 2.2hour period. For A-31, theminimum combustion zonetemperature shall be 1,400 F,averaged over any consecutive 3.4hour period.

S24 and A31 abate organic emissionsfrom wastewater equipment subject to40 CFR 61 Subpart FF, an existingapplicable requirement in the Title Vpermit. Per 40 CFR 61.355(i)(3),compliance of a control device andparameter to be monitored (i.e.,temperature) is based on an averagingperiod determined by source test.

Condition1240.II.58b

Modify Basis for Condition No.1240.II.58b, in order to clarify thatthe basis for the Condition is tomonitor compliance throughperformance testing and notengineering calculations, to read asfollows: “Basis: 40 CFR60.113b(c)(1)(ii) and 60.113b(c)(2);40 CFR 60.473(c); 40 CFR61.354(c)(1) and 61.354(c)(4);Regulation 2-6-409.2.2, 2-6-414).”

Condition No. 1240.II.58b, applicableto S24 and A31, should reference in the“basis” for the condition citations to theperformance test compliance measuresinstead of to the engineeringcalculations.

29. 12/1/03 No IV-P S24 40 CFR 61 Subpart FF Modify Table IV-P to deletereferences to:40 CFR § 61.356(f)(2)40 CFR § 61.356(f)(2)(i)40 CFR § 61.356(f)(2)(i)(A)40 CFR § 61.356(f)(2)(i)(C)

S24 is not subject to § 61.356(f)(2)recordkeeping for engineeringcalculations because it is monitored byperformance tests prescribed by§ 61.349(c)(2) rather than theengineering calculations described in§ 61.349(c)(1). 40 CFR Part 61 SubpartFF § 61.349(c) allows the facility todemonstrate compliance either byperformance tests or throughengineering calculations. The AsphaltPlant has elected to comply throughperformance tests for S24. Indeed,specific Permit conditions for thissource require the Plant to demonstratecompliance by performance tests.

30. 12/1/03 No IV-P S24 40 CFR 61 Subpart FF Modify Table IV-P to deletereferences to:40 CFR § 61.356(j)(4)40 CFR § 61.357(d)(7)(iv)(A)Modify Table IV-P to add referencesto:40 CFR § 61.356(j)(3)(i)40 CFR § 61.356(j)(6)40 CFR § 61.357(d)(7)(iv)(C)

S24 is a process heater, subject to§§ 61.356(j)(6), 61.356(j)(3)(i) and61.356(d)(7)(iv)(C). Sections61.356(j)(4) and 61.356(d)(7)(iv)(A),applicable to a thermal oxidizer, are notapplicable to a process heater.

31. 12/1/03 No IV-AH S66 40 CFR 61 Subpart FF Modify Table IV-AH to deletereference to 40 CFR § 61.349(c)(1)(engineering calculations) and addreference to § 61.349(c)(2)(performance test).

S66 is an oil-water separator, controlledby S24 and A31. S66 is not subject to61.349(c)(1) (recordkeeping forengineering calculations) because itscontrol devices are monitored byperformance tests prescribed by§ 61.349(c)(2). 40 CFR Part 61 SubpartFF § 61.349(c) allows the facility todemonstrate compliance either byperformance tests or throughengineering calculations. The AsphaltPlant has elected to comply throughperformance tests for S24 and A31.Indeed, specific Permit conditions forthese sources require the Plant todemonstrate compliance byperformance tests.

32. 12/1/03 No IV-AN Components

40 CFR 61 Subpart FF Modify Table IV-AN to deletereferences to 40 CFR § 61.347(b)and§ 61.349(f)

The bases cited for these requirementsare neither factually nor legally correct.

The Permit erroneously includes therequirements for quarterly visualequipment inspections for oil-waterseparators and closed vent systems andcontrol devices as part of the fugitivemonitoring program.

Visual equipment inspections arerequired for these sources, but theseinspections have no reasonablerelationship to detecting fugitiveemissions and, more importantly, theDistrict has no legal basis for includingfugitive emissions limits as the basis forthe visual equipment inspections.

33. 12/1/03 No IV-AP A31 40 CFR 61 Subpart FF Modify Table IV-AP to deletereference to 40 CFR§ 61.356(f)(2)(A) (recordkeeping forengineering calculations).

A31 is not subject to §§ 61.356(f)(2)(recordkeeping for engineeringcalculations) because its control devicesare monitored by performance testsprescribed by § 61.349(c)(2).

In accordance with Application No.7471, revise Condition No. 20278 inthe Permit as follows:For Part 1, increase asphaltthroughput for S70 from 17,591 to400,000 tpy.

For Part 2, increase additivethroughput for S69 from 2,650 to20,000 tpy.For Part 5, delete operating hourslimit for S70.

For Part 6b, delete recordkeepingrequirements for S70 operatinghours.See Attachment 4, pages 36-38, forthe requested modification.

The District approved Application No.7471 on October 11, 2003, whichallowed the Plant to increase throughputlimits for Polymer Modified Asphaltproduction at S69 and S70.These permit conditions fail toincorporate the throughput changesapproved by Application No. 7471.

35. 12/1/03 No VIII NA 40 CFR 61.349(a)(2)(i) Change acceptable test method to“40 CFR Part 61 Subpart FF,§ 61.355 Test Methods, Procedures,and Compliance Provisions” asrequired under § 61.349(a)(2)(i) (A).

40 CFR Part 61 Subpart FF§ 61.349(a)(2)(i) allows the facility todemonstrate compliance with thatsection either by § 61.349(a)(2)(i)(A)(>95% reduction) or § 61.349(a)(2)(i)(B) (< 20 ppm VOC outlet). The Planthas elected to comply in accordancewith the standard to achieve >95%reduction.

1. 4/14/04 NEW COMMENT VII-E S9 VOC BAAQMD 8-5-322.1

Make the following changesin this monitoringrequirement for the IFRsemiannual visual inspectionthrough the viewports:

Citation of Limit:BAAQMD 8-5-305.2, 8-5-305.3, 8-5-320.3.2, 8-5-322.1

Limit: No visual gaps inoutermost seal, orinaccessible tank fittings, orviewports. No holes, tears oropenings in outermost sealfabric.

Monitoring Type: Visualinspection

Because this is an internal floatingroof tank, the outermost seal which isthe secondary seal, as well as anyinaccessible tank fittings are to beinspected semi-annually by a visualinspection in accordance with 8-5-402.2. There is no semiannualrequirement for a “secondary sealinspection” as stated in the Permit forthis monitoring requirement.

2. 4/14/04 NEW COMMENT VII-E S9 VOC BAAQMD 8-5-320.4.3

Make the following changesin this monitoringrequirement for adding tankfitting gaps to the secondaryseal gaps:

Monitoring RequirementCitation: 8-5-402.1

Monitoring Frequency:P/every 10 years

Monitoring Type: Secondaryseal inspection

Secondary seal gaps are onlymeasured every 10 years, so thisrequirement to add fitting gaps is onlydone every 10 years.

Change Citation of Limit to:“40 CFR 61.349(f)”

Change Limit to “No looseconnections or visible holesin ductwork or piping.”

The bases cited for these requirementsare neither factually nor legallycorrect.

The Permit erroneously cites toinapplicable federal regulatory limitsfor monitoring fugitive emissionsfrom oil water separators and closedvent systems and control devices.

The methods for measuring fugitiveemissions are explicitly described inthe legally applicable federalregulations (which cite to EPAMethod 21 annual inspections).Visual equipment inspections arerequired for these sources, but theseinspections have no reasonablerelationship to detecting fugitiveemissions and, more importantly, theDistrict has no legal basis forincluding fugitive emissions limits asthe basis for the visual equipmentinspections.

In accordance withApplication No. 7471, reviseCondition No. 20278 in thePermit as follows:For Part 1, increase asphaltthroughput for S70 from17,591 to 400,000 tpy.

For Part 2, increase additivethroughput for S69 from2,650 to 20,000 tpy.

For Part 5, delete operatinghours limit for S70.

The District approved Application No.7471 on October 11, 2003, whichallowed the Plant to increasethroughput limits for PolymerModified Asphalt production at S69and S70.

These permit conditions fail toincorporate the throughput changesapproved by Application No. 7471.The Tables in Section VII, whichshould incorporate the condition,should be updated to incorporate thenew throughput levels and theelimination of the Hours of OperationLimit, Parts 5 and 6 of the condition inthe December 1, 2003 Major FacilityReview Permit.

Method 21Inspection

Footnotes to Table VII-AL above: a Valves are inspected pursuant to BAAQMD-approved Alternative Inspection Schedule that satisfies therequirements of 8-18-404. Valves that have not been found to be leaking for the five prior quarters are placed on theannual inspection schedule. b Connectors are inspected pursuant to a BAAQMD-approved Connector Inspection Program that satisfies therequirements of 8-18-401.6. Under this program, 20% of all of the refinery’s connectors are inspected each year. c The 40 CFR 60.483-2 (Subpart VV) alternative screening schedule for valves is analogous to the ValeroAlternative Inspection Schedule (see footnote “a”) with two exceptions: 40 CFR 60.483-2 uses a leak definition of10,000 ppm VOC rather than 100 ppm TOC, and 40 CFR 60.483-2 requires that the percentage of valves leakingfacility-wide (at 10,000 ppm) must have been less than 2% for the five-quarter time period. For process unitscovered by refinery MACT, 63.648(a)(2) allows the percentage leaking to be determined on a refinery-wide basis.This applies to all process units except NSPS process units except Dimersol, which is not subject to MACT. Finally,any valve subject to Subpart VV must individually comply with BAAQMD Rule 8-18-404 (5 quarters with no leaksat 100 ppm) in order to be allowed to be screened less frequently than quarterly. As a practical matter, Subpart VVis effectively less stringent than the Valero Alternative Inspection Schedule.

Modify condition language torequire O2 monitors only onsources with maximum firingrate greater than 25 MM Btu/hr.

Delete Part 2 from Tables IV-Nand O for S20 and S21 (< 25MM Btu/hr).


The requirement to install O2 monitors onsmall (<25 MM Btu/hr) sources is notnecessary since there is no minimum ormaximum O2 requirement for these sources perCondition 20617, Part 3.b.


Condition 20617,Part 3.b

Delete language that specifieslow fire is at 20% of themaximum rated capacity.


Emissions from small sources are insignificant.This requirement is not discussed in theStatement of Basis.

6. 4/14/04 NEW COMMENT VI S7S20S34S24S26S35S173


Delete “at all times ofoperation.” and replace with“This operational range shall bemaintained within a tolerance ofequal to or less than 10% formeasurement uncertainty.”


An allowable tolerance should be established toaccount for natural source testing variability.

See Attachment C.2 for supporting rationale.


Condition 20617,Part 5.a

Extend table to include refineryNOx Box sources.




Condition 20617,Part 5.b

Modify the condition languageby adding two commas asshown.See Attachment C.1 forproposed revisions to Condition20617.

Editorial comments clarify condition language,based on discussions with District staff.

Condition 20617,Part 6.a

Add a statement clarifying thatsource testing required after aNOx Box deviation shallreasonably represent thedeviation conditions.

Modify the sentence specifyingthe time frame for the sourcetest to delete “no later than thenext regularly scheduled sourcetest period, or within 8 months,whichever is sooner.” andreplace it with “within 8months of the event.”

Add “application” after “permitamendment”.


To exactly replicate an “out of the box”condition over three runs can take a significantamount of time without actually obtaining amore accurate test result.

See Attachment C.2 for supporting rationale forproposed tolerance level.

While it is advantageous to conduct “out of thebox” testing as soon as possible, there may beoperational reasons to test at a later date

For more details see WSPA commentssubmitted to the District on 4/9/04.


Condition 20617,Part 6.a.1

Change “lower than” to “lessthan or equal to” in the firstsentence of Case 1.

Modify the condition languageto specify “by more than 5%” asthe maximum allowableexceedance of the higher NOxemission factor or the CO limit.

Modify the last sentence fromthe negative “will not beconsidered to be in violation” tothe positive “will be consideredto be in compliance”


Clarifies the range of conditions that apply toCase 1 where source test results are less than“or equal to” the Emission Factor.


Semi-annual source tests should have atolerance of 5% because the emissions involvedare miniscule in relation to the calculationsinvolved, the paperwork for both the Districtand facility is extensive and provides noenvironmental benefit. This provision willoperate in both directions, since the facilitywould not be submitting for REDUCTIONS ifa single source test result showed it 5%, oreven 10% lower.

Condition 20617,Parts 6.A.2 and7.B

Modify the condition languageto specify “Part 5A” as thesource of permitted emissionconcentrations or emission rates.

Modify the condition languageto specify “by more than 5%”exceedances as the trigger pointfor further action.


Clarifies Condition 20617, Part 5.A as thesource of the permitted emission concentrationsor emission rates.

Semi-annual source tests should have atolerance of 5% because the emissions involvedare miniscule in relation to the calculationsinvolved, the paperwork for both the Districtand facility is extensive and provides noenvironmental benefit. This provision willoperate in both directions, since the facilitywould not be submitting for REDUCTIONS ifa single source test result showed it 5%, oreven 10% lower.


Condition 20617,Parts 6.a.2.A;6.a.2.A.1; and6.a.2.A.2

Modify the condition languageto clarify the basis fordetermining the period that NOxIERCs need to be retroactivelyapplied to maintain compliancewith the refinery-wide NOxlimit for the two differentconditions that can occur.


Part 1 allows NOX IERC usage. However,additional language is proposed in Part6.a.2.A to clarify that the facility will be incompliance with 9-10-301 unless there areinsufficient NOX IERCs provided.

*2. The owner/operator of each source with a maximum firing rate greater than 25 MMBtu/hr listed in Part 1shall properly install, properly maintain, and properly operate an O2 monitor and recorder. This Part shall beeffective September 1, 2004. (Basis: Regulation 9-10-502)

*3. The owner/operator shall operate each source listed in Part 1 that does not have a NOx CEM withinspecified ranges of operating conditions (firing rate and oxygen content) as detailed in Part 5. The ranges shallbe established by utilizing data from district-approved source tests. (Basis: Regulation 9-10-502)

a. The NOx Box for units with a maximum firing rate of 25 MMBH or more shall be established using theprocedures in Part 4.

b. The NOx Box for units with a maximum firing rate less than 25MMBH shall be established as follows:High-fire shall be the maximum rated capacity. There shall be no maximum or minimum O2.

*4. The owner/operator shall establish the initial NOx box for each source subject to Part 3 by June 1, 2004.The NOx Box may consist of two operating ranges in order to allow for operating flexibility and to encourageemission minimization during standard operation. (Basis: Regulation 9-10-502) The procedure for establishingthe NOx box is

a. Conduct district approved source tests for NOx and CO, while varying the oxygen concentration and firingrate over the desired operating ranges for the furnace;

b. Determine the minimum and maximum oxygen concentrations and firing rates for the desired operatingranges (Note that the minimum O2 at low-fire may be different than the minimum O2 at high-fire. Thesame is true for the maximum O2). The owner/operator shall also verify the accuracy of the O2 monitor onan annual basis.

c. Determine the highest NOx emission factor (lb/Mmbtu) over the preferred operating ranges whilemaintaining CO concentration below 200 ppm; the owner/operator may choose to use a higher NOxemission factor than tested.

d. Plot the points representing the desired operating ranges on a graph. The resulting polygon(s) are the NOxBox, which represents the allowable operating range(s) for the furnace under which the NOx emissionfactor from part 5a is deemed to be valid.

1. The NOx Box can represent/utilize either one or two emission factors.2. The NOx Box for each emission factor can be represented either as a 4- or 5-sided polygon

The NOx box is the area within the 4- or 5-sided polygon formed by connecting the sourcetest parameters that lie about the perimeter of successful approved source tests. The sourcetest parameters forming the corners of the NOx box are listed in Part 5.

e. Upon establishment of each NOx Box, the owner/operator shall prepare a graphical representation of thebox. The representation shall be made available on-site for APCO review upon request. The box shall alsobe submitted to the BAAQMD with permit amendments.

During these conditions the means fordetermining compliance with the refinery wide limit shall be accomplished using the method describedin 9-10-301.2 (i.e. units out of service & 30-day averaging data).

c. Part 5a does not apply during any source test required or permitted by this condition. See Part 7 for theconsequences of source test results that exceed the emission factors in Part 5.

*6. NOx Box Deviations (Basis: Regulation 9-10-502)

a. The owner/operator may deviate from the NOx Box (either the firing rate or oxygen limit) providedthat the owner/operator conducts a district approved source test which reasonably represents the pastoperation outside of the established ranges. The source test representing the new conditions shall beconducted within eight months of the event . The source test results will establish whether the sourcewas operating outside of the emission factor utilized for the source. The source test results shall besubmitted to the district source test manager within 45 days of the test. As necessary, a permitamendment application shall be submitted.

1. Case 1: Source Test result is less than or equal to Emission FactorIf the results of this source test do not exceed the higher NOx emission factor in Part 5 bymore than 5%, or the CO limit in Part 9, the unit will be considered to be in complianceduring this period for operating out of the "box."The facility may submit an accelerated permit program permit application to request anadministrative change of the permit condition to adjust the NOx Box operating range(s),based on the new test data.

2. Case 2: Source Test result is higher than Emission FactorIf the results of this source test exceed the permitted emission concentrations or emission ratesin Part 5a by more than 5% then the actions described below must be followed:


(continued)

Submitted 4/14/04 4

A. Utilizing the measurement, the owner/operator shall perform an assessment of compliancewith Section 9-10-301 as described below.

1. “Out of Box” Condition – for the day(s) in which the “out of box “condition(s) occurred ensure sufficient NOx IERCs will be provided thatday (or those days) to ensure the facility is in compliance with therefinery wide limit.

2. Within the Box but Higher Emission Factor Only – The higher emissionfactor must be retroactively applied back to the date of the previoussource test and sufficient NOx IERCs provided for that time period toensure the facility is in compliance with the refinery wide limit specifiedin 9-10-301. The unit will be considered in violation of Regulation 9-10-301 for each day there are insufficient NOx IERCs provided to bring therefinery wide average into compliance with 9-10-301.

B. The facility may submit a permit application to request an alteration of the permitcondition to change the NOx emission factor and/or adjust the operating range, based onthe new test data.

b. Reporting: The owner/operator must report conditions outside of box within 96 hours of occurrence.

*7. For each source subject to Part 3, the owner/operator shall conduct source tests at the schedule listedbelow. The source tests are performed in order to measure NOx, CO, and O2 at the as-found firing rate, orat conditions reasonably specified by the APCO. The source test results shall be submitted to the districtsource test manager within 45 days of the test. (Basis: Regulation 9-10-502)

a. Source Testing Schedule

1. Heater < 25 MMBtu/hr

One source test per consecutive 12-month period. The time interval between source testsshall not exceed 16 months.

2. Heaters ≥ 25 MMBtu/hr

Two source tests per consecutive 12-month period. The time interval between sourcetests shall not exceed 8 months and not be less than 5 months apart. The source testresults shall be submitted to the district source test manager within 45 days of the test.

b. Source Test Results > NOx Box Emission Factor

If the results of any source test under this part exceed the permitted concentrations oremission rates in Part 5a by more than 5%, the owner/operator shall follow therequirements of Part 6.a.2. If the owner/operator chooses not to submit an application torevise the emission factor, the owner/operator shall conduct another Part 7 source test, atthe same conditions, within 90 days of the initial test.

c. If a source is shutdown during the period when a source test is scheduled (i.e., outside of normalroutine maintenance turnaround schedule), then the owner/operator shall conduct the source testwithin 30 days of start up of the source.


(continued)

Submitted 4/14/04 5

*8. For each source listed in Part 1 with a NOx CEM installed, the Owner/Operator shall conduct semi-annual District approved CO source tests at as-found conditions. The time interval between source testsshall not exceed 8 months. District-conducted CO emission tests associated with District-conducted NOxCEM field accuracy tests may be substituted for the CO semi-annual source tests. (Basis: Regulation 9-10-502)

*9. For any source with a maximum firing rate greater than 25 MMBtu/hr listed in Part 1 for which anytwo source test results over any consecutive five year period are greater than or equal to 200 ppmv CO at3% O2, the owner/operator shall properly install, properly maintain, and properly operate a CEM tocontinuously measure CO and O2. The owner/operator shall install the CEM within the time periodallowed in the District's Manual of Procedures. (Basis: Regulation 9-10-502, 1-522)

*10.In addition to records required by Regulation 9-10-504, the owner/operator must maintain records ofall source tests conducted to demonstrate compliance with Parts 1 and 5. These records shall be kept onsite for at least five years from the date of entry in a District approved log and be made available to Districtstaff upon request. (Basis: Regulation 9-10-504)

Attachment C.2Rationale for Proposed NOx Box Source Testing Tolerance - Permit Condition 20617, Part 5 - Facility A0901

Therefore, there is a large margin for error introduced in the ACP calculation requirements themselves which directionally increases the likelihood of exceeding the emissions estimates that would have been yielded had CEMs been installed.

Thus, this requested amendment does nothing to harm the demonstration of alternative compliance assurance. Source tests are logistically and operationally burdensome, andreturning to identical and previous operating conditions is even more costly, with the potential to increase emissions of NOx and other pollutants.

WSPA believes it to be within the District’s authority to continue a 10 to 20% tolerance for measurement uncertainty.

The permit conditions in question establish equivalency for those heaters and boilers regulated by Regulation 9-10 using an Alternative Compliance Plan (ACP) under the provisions of that rule. Based on a direct equivalency, the District previously allowed a tolerance of 20% for source testing in its “District guidance on Equivalent Verification” issued June 2000 for the ACP.

There is inherent variability in all test methods and this is well documented in scientific and regulatory literature. This is the basis for tolerances established in regulations and regulatory reference test methods. Tolerances for systemic and random errors of 20% have been established for CEMs. EPA and CARB Reference Test Methods verify CEMsresults based on source testing results. An analysis of measurement uncertainty in source testing can be verified by a review of the various measurements required for source testing, the potential for random error, and the potential for systemic errors such as occur in data handling and collection. Based on a review of scientific literature and various federal, state, and local reference test methods, this measurement uncertainty is between 10 to 20% based on the specific source testing configuration, measurement devices, the data collection protocol, and the data handling techniques.

In addition, calculation of emissions using the method specified in the June 2000 guidance result in extremely conservative estimates. WSPA members report that emissions calculated according to the ACP may be overstated by as much as 30%. This finding is intuitive because all operating conditions are calculated at the highest emission factor (worst operating case scenario), when most operating conditions are lower than the highest firing and O2 rates.
