        (c)      Upon detecting an excursion, the permittee shall restore operation of the pollutant-specific emission
                 unit to its normal or usual manner of operation as expeditiously as practicable in accordance with
                 good air pollution control practices. The response shall include minimizing the period of any start-up,
                 shutdown or malfunction and taking any corrective actions to restore normal operation and prevent
                 the likely recurrence of the cause of an excursion.
        (d)      If the permittee identifies a failure to achieve compliance with an emission limit for which the
                 monitoring did not provide an indication of an excursion while providing valid data, or the results of
                 compliance or performance testing documents a need to modify the existing indicator ranges, the
                 permittee shall promptly notify the Division and, if necessary, submit a proposed modification to this
                 permit to address the necessary monitoring changes.

               KKK.
       (c)     The permittee shall meet all reporting and recordkeeping requirements as specified in Subpart HH
               $63.774 and 63.775.

(P63-HH2)     OPERATION & MAINTENANCE REQUIREMENTS
       [40 CFR 63 Subpart HH $60.762 and WAQSR Ch 5, Sec 3(h)(ivXA)(II)]
       (a)    The provisions set forth in Subpart HH shall apply at all times except during startups or shutdowns,
               during malfunctions, and during periods of non-operation of the affected sources (or specific portion
              thereof) resulting in cessation of the emissions to whlch Subpart HH applies. However, during the
               startup, shutdown, malfunction, or period of non-operation of one portion of an affected source, all
              emission points which can comply with the specific provisions to which they are subject must do so
              during the startup, shutdown, malfunction, or period of non-operation.
       (b)     The permittee shall not shut down items of equipment that are required or utilized for compliance
               with the provisions of Subpart HH during times when emissions are being routed to such items of
               equipment, if the shutdown would contravene requirements of Subpart HH applicable to such items
               of equipment. This paragraph does not apply if the item of equipment is malfunctioning, or if the
              permittee must shut down the equipment to avoid damage due to a contemporaneous startup,
               shutdown, or malfunction of the affected source or a portion thereof.
       (c)     During startups, shutdowns, and malfunctions when the requirements of Subpart HH do not apply
              pursuant to paragraphs (a) and (b) of this section, the permittee shall implement, to the extent
               reasonably available, measures to prevent or minimize excess emissions to the maximum extent
               practical. For purposes of thls paragraph, the term "excess emissions" means emissions in excess of
               those that would have occurred if there were no startup, shutdown, or malfunction, and the permittee
               complied with the relevant provisions of Subpart HH. The measures to be taken shall be identified
               in the applicable startup, shutdown, and malfunction plan required in condition P63-HH3 of this
              permit.
       (d)     Malfunctions shall be corrected as soon as practicable after their occurrence in accordance with the
               startup, shutdown, and malfunction plan required in condition P63-HH3 of this permit

(P63-HH3)        STARTUP, SHUTDOWN, & MALFUNCTION PLAN [WAQSR Ch 5, Sec 3(h)(iv)(C)]
       (a)       The permittee shall develop and implement a written startup, shutdown, and malfunction plan that
                 describes, in detail, procedures for operating and maintaining the source during periods of startup,
                 shutdown, and malfunction and a program of corrective action for malfunctioning process and air
                 pollution control equipment used to comply with Subpart HH. This plan shall be developed by the
                 permittee by the source's compliance date for Subpart HH.
         (b)     During periods of startup, shutdown, and malfunction, the permittee shall operate and maintain the
                 affected sources (including associated air pollution control equipment) in accordance with the

Permit No. 3 1-039                                                                                          Page 13
                procedures specified in the startup, shutdown, and malfunction plan developed under paragraph (a)
                of this condition.
                When actions taken by the permittee during a startup, shutdown, or malfunction (including actions
                taken to correct a malfunction) are consistent with the procedures specified in the startup, shutdown,
                and malfunction plan, the permittee shall keep records for that event that demonstrate the procedures
                specified in the plan were followed. These records may take the form of a "checklist," or other
                effective form of recordkeeping, that confirms conformance with the startup, shutdown, and
                malfunction plan for that event.
                If an action taken by the permittee during a startup, shutdown, or malfunction (including an action
                taken to correct a malfunction) is not consistent with the procedures specified in the startup,
                shutdown, and malfunction plan, the permittee shall record the actions taken for that event.
                The permittee shall keep the written startup, shutdown, and malfunction plan on record after it is
                developed to be made available for inspection, upon request, by the Admistrator for the life of each
                affected source or until the affected source is no longer subject to the provisions of Chapter 5, Section
                3. In addition, if the startup, shutdown, and malfunction plan is revised, the permittee shall keep
                previous (i.e., superseded) versions of the startup, shutdown, and malfunction plan on record, to be
                made available for inspection, upon request, by the Admistrator, for a period of 5 years after each
                revision to the plan.
                To satisfy the requirements of this condition to develop a startup, shutdown, and malfunction plan,
                the permittee may use the affected source's standard operating procedures (SOP) manual, or an
                Occupational Safety and Health Administration (OSHA) or other plan, provided the alternative plans
                meet all the requirements of Chapter 5, Section 3 and are made available for inspection when
                requested by the Administrator.
                If the startup, shutdown, and malfunction plan fails to address or inadequately addresses an event that
                meets the characteristics of a malfunction but was not included in the startup, shutdown, and
                malfunction plan at the time the permittee developed the plan, the permittee shall revise the startup,
                shutdown, and malfunction plan within 45 days after the event to include detailed procedures for
                operating and maintaining the source during similar malfunction events and a program of corrective
                action for similar malfunctions of process or air pollution control equipment.

                GENERAL RECORDKEEPING REQUIREMENTS [WAQSR Ch 5, Sec 3(l)(ii)(A) and (B)]
                The permittee shall maintain files of all information (including all reports and notifications) required
                by Chapter 5, Section 3 recorded in a form suitable and readily available for expeditious inspection
                and review. The files shall be retained for at least 5 years following the date of each occurrence,
                measurement, maintenance, corrective action, report, or record. At a minimum, the most recent
                2 years of data shall be retained on site at the facility. The remaining 3 years of data may be retained
                off site. Such files may be maintained on microfilm, on a computer, on computer floppy disks, on
                magnetic tape disks, or on microfiche.

Hydrogen Sulfide: [WAQSR Ch 3, Sec 71

(S2)    Any exit process gas stream containing hydrogen sulfide whlch is discharged to the atmosphere from any
        source shall be vented, incinerated, flared or otherwise disposed of in such a manner that ambient sulfur
        dioxide and hydrogen sulfide standards are not exceeded.

Odors: [WAQSR Ch 2, Sec 111

(S3)    (a)     The ambient air standard for odors from any source shall be limited to an odor emission at the
                property line which is undetectable at seven dilutions with odor free air as determined by a
                scentometer as manufactured by the Barnebey-Cheney Company or any other instrument, device,
                or techmque designated by the Division as producing equivalent results. The occurrence of odors
                shall be measured so that at least two measurements can be made within a period of one hour,
                these determinations being separated by at least 15 minutes.
        (b)     Odor producing materials shall be stored, transported, and handled in a manner that odors
                produced from such materials are confined and that accumulation of such materials resulting from
                spillage or other escape is prevented.

**BACTW "Bestavailable control technology" means an emission limitation (including a visible emission standard)
          or
based on the maximum degree of reduction of each pollutant subject to regulation under the WAQSR or regulation
under the Federal Clean Air Act, which would be emitted from or which results for any proposed major emitting facility
or major modification which the Administrator, on a case-by-case basis, taking into account energy, environmental, and
economic impacts and other costs, determines is achievable for such source or m ~ ~ c a t i through application or
                                                                                                 on
production processes and available methods, systems, and techniques, including fuel cleaning or treatment or innovative
fuel combustion techniques for control of such pollutant. If the Administratordetermines that technologicalor economic
limitations on the application of measurement methodology to a particular class of sources would make the imposition
of an emission standard infeasible, he may instead prescribe a design, equipment, work practice or operational standard
or combination thereof to satisfy the requirement of Best Available Control Technology. Such standard shall, to the
degree possible, set forth the emission reduction achievable by implementation of such design, equipment, work
practice, or operation and shall provide for compliance by means which achieve equivalent results. Application of
BACT shall not result in emissions in excess of those allowed under Chapter 5, Section 2 of the WAQSR and any other
new source performance standard or national emission standards for hazardous air pollutants promulgated by EPA but
not yet adopted by the state.

"Department" means the Wyoming Department of Environmental Quality or its Director.

"Director" means the Director of the Wyoming Department of Environmental Quality.

"Division" means the Air Quality Division of the Wyoming Department of Environmental Quality or its Administrator.

"Emergency" means any situation arising from sudden and reasonably unforeseeable events beyond the control of the
source, including acts of God,which situation requires immediatecorrectiveaction to restore nonnal operation, and that
causes the source to exceed a technology-based emission limitation under the permit, due to unavoidable increases in
emissions attributable to the emergency. An emergency shall not include noncompliance to the extent caused by
improperly designed equipment, lack of preventative maintenance, careless or improper operation, or operator error.

"EPA" means the Administrator of the U.S. Environmental Protection Agency or the Administrator's designee.

'*Fuel-burningequipment" means any furnace, boiler apparatus, stack, or appurtenances thereto used in the process
of burning fuel or other combustible material for the purpose of producing heat or power by indirect heat transfer.

"Fugitive emissions" means those emissions which could not reasonably pass through a stack chimney, vent, or other
functionally equivalent opening.

"Insignificant activities" means those activities which are incidental to the facility's primary business activity and
which result in emissions of less than one ton per year of a regulated pollutant not included in the Section 112 (b) list
of hazardous air pollutants or emissions less than 1000pounds per year of a pollutant regulated pursuant to listing under
Section 112 (b) of the Act provided, however, suchemissionlevels of hazardous air pollutants do not exceed exemptions
based on insignificant emission levels established by EPA through rulemaking for modification under Section 112 (g)
of the Act.

"MACT" or "Maximum achievable control technology" means the maximum degree of reduction in emissions that
is deemed achievable for new sources in a category or subcategory that shall not be less stringent than the emission
control that is achieved in practice by the best controlled similar source, as determined by the Administrator. Emission
standards promulgated for existing sources in a category or subcategory may be less stringent than standards for new
sources in the same category or subcategory but shall not be less stringent, and may be more stringent than:

         (a)      the average emission limitation achieved by the best performing 12 percent of the existing sources
                  (for which the A d d s t r a t o r has emission information), excluding those sources that have, within 18
                  months before the emission standard is proposed or within 30 months before such standard is
                  promulgated, whichever is later, first achieved a level of emission rate or emission reduction which
                  complies, or would comply if the source is not subject to such standard, with the lowest achievable
                  emission rate applicable to the source category and prevailing at the time, in the category or
                  subcategory for categories and subcategories with 30 or more sources, or

         (b)      the average emission limitation achieved by the best performing five sources (for which the
                  Administrator has or could reasonably obtain emissions information) in the category or subcategory
                  for categories or subcategories with fewer than 30 sources.

"Modification" means any physical change in, or change in the method of operation of, an affected facility which
increases the amount of any air pollutant (to which any state standards applies) emitted by such facility or which results
in the emission of any such air pollutant not previously emitted.

"Permittee" means the person or entity to whom a Chapter 6, Section 3 permit is issued.

 "Potentialto emit" means the maximum capacity of a stationary source to emit any air pollutant under its physical and
operational design. Any physical or operational limitation on the capacity of a source to emit an air pollutant, including
air pollution control equipment and restrictions on hours of operation or on the type or amount of material combusted,
stored or processed, shall be treated as part of its design if the limitation is enforceable by EPA and the Division. This
term does not alter or affect the use of this term for any other purposes under the Act, or the term "capacity factor" as
used in title IV of the Act or the regulations promulgated thereunder.

"Regulated air pollutant" means the following:

         (a)      Nitrogen oxides (NO,) or any volatile organic compound;

                            promulgate a standard by the date established pursuant to Section 112(e) of the Act, any
                            pollutant for which a subject source would be major shall be considered to be regulated on
                            the date I8 months after the applicable date established pursuant to Section 112(e) of the
                            Act; and

                   (ii)     Any pollutant for which the requirements of Section 112(g)(2) of the Act have been met, but
                            only with respect to the individual source subject to Section 112(g)(2) requirement.

         (         Pollutants regulated solely under Section 112(r)of the Act are to be regulated only with respect to the
                   requirements of Section 112(r) for pernlits issued under this Chapter 6, Section 3 of the WAQSR.

Re:    Changes to Renewal Operating Permit Application
       Douglas Gas Plant
       Kinder Morgan Operating L.P. "A"


Dear Mr. Stoll:

Kinder Morgan Operating L.P. "A"(KM0LPA) hereby submits the following change for
consideration regarding renewal of Operating Permit Application for the Douglas Gas Plant.



CAM Plan Table 1, Indicator No. 2; "Recommend changing minimum temperature rise across
the catalyst to 10 degrees F". KMOLPA was allowed to complete field-testing to establish
actual differential temperature data, to be used in the CAM Plan for an indicator of catalyst
efficiency. The above temperature rise number is recommended based on actual test data
obtained from testing and recommendations from manufactures.


Manufactures stated that, observed rise may only be a few degrees to as much as 100 degrees,
depending on load and RPM of the engine. The lowest temperature rise number obtained during
testing at Douglas Gas Plant was 1 1 degrees. Note that Douglas Gas Plant engines bum only
pipeline quality natural gas and not field gas like booster station engines. A spreadsheet showing
the actual field test data and letters from catalyst manufactures are included for reference.


Attached is a revised Table 1 and YPM sheet reflecting recommended changes to the approved
CAM Plan.

State of Wyomine Portable Analvzer Monitoring Protocol

1. APPLICABILITY AND PRINCIPLE


1.1 Applicability. This method is applicable to the determination of nitrogen oxides (NO and
NO,), carbon monoxide (CO), and oxygen (0,) concentrations in controlled and uncontrolled
emissions from natural gas-fired reciprocating engines, combustion turbines, boilers, and
process heaters using portable analyzers with electrochemical cells. The use of reference
method equivalent analyzers is acceptable provided the appropriate reference method
procedures in 40 CFR 60, Appendix A are used. Due to the inherent cross sensitivities of the
electrochemical cells, this method is not applicable to other pollutants.


1.2 Principle. A gas sample is continuously extracted from a stack and conveyed to a
portable analyzer for determination of NO, NO,, CO, and 0, gas concentrations using
electrochemical cells. Analyzer design specifications, performance specifications, and test
procedures are provided to ensure reliable data. Additions to or modifications of vendor-
supplied analyzers (e.g. heated sample line, flow meters, etc.) may be required to meet the
design specifications of this test method.


2. RANGE AND SENSITIVITY


2.1 Analytical Range. The analytical range for each gas component is determined by the
electrochemical cell design. A portion of the analytical range is selected to be the nominal
range by choosing a span gas concentration near the flue gas concentrations or permitted
emission level in accordance with Sections 2.1.1, 2.1 -2 and 2.1.3.


2.1.1 CO and NO Span Gases. Choose a span gas concentration such that the average stack
gas reading for each test is greater than 25 percent of the span gas concentration.

reading for each test is greater than 25 percent of the span gas concentration. Alternatively,
choose the span gas concentration such that it is not greater than the ppm concentration value
of the NO span gas. The tester should be aware N.0, cells are generally designed to measure
much lower concentrations than NO cells and the span gas should be chosen accordingly. If
concentration results exceed 125 percent of the span gas at any tirne during the test, then the      -

test for that pollutant is invalid.

State of W~ornine

6.2 Linearity Check. Conduct the following procedure once for each nominal range to be
used on each electrochemical cell (NO, NO,, CO, and 0,). After a linearity check is
completed, it remains valid for five consecutive calendar days. After the five calendar day
period has elapsed, the linearity check must be reaccomplished. Additionally, .reaccomplish
the linearity check if the cell is replaced. (If the stack NO, concentration is less than 5 % of
the stack NO concentration as determined using the emission test procedures under Section 7,
the NO, linearity check is not required. However, the NO, cell shall be calibrated in
accordance with the manufacturer's instructions, the pretest calibration error check and post
test calibration calibration error check shall be conducted in accordance with Section 7, and
the test results shall be added to the NO test values to obtain a total NOx concentration.)


6.2.1 Linearity Check Gases. For each cell obtain the following gases: zero (0-0.25 percent
of nominal range), mid-level (40-60 percent of span gas concentration), and span gas (selected
according to Section 2.1).


6.2.2 Linearity Check Procedure. If the analyzer uses an external interference gas scrubber
with a color indicator, using the analyzer manufacturer's recommended procedure, verify the
scrubbing agent is not depleted. After calibrating the analyzer with zero and span gases, inject
the zero, mid-level, and span gases appropriate for each nominal range to be used on each cell.
Gases need not be injected through the entire sample handling system. Purge the analyzer
briefly with ambient air between gas injections. For each gas injection, verify the flow rate is
constant and the analyzer responses have stabilized before recording the responses on Form A.


6.3 Interference Check. A CO cell response to the NO and NO, span gases or an NO cell
response to the NO, span gas during the linearity check may indicate interferences. If these
cell responses are observed during the linearity check, it may be desirable to quantify the CO
cell response to the NO and NO, span gases and the NO cell response to the NO, span gas
during the linearity check and use estimated stack gas CO, NO and NO, concentrations to

evaluate whether or not the portable analyzer will meet the post test interferen,~
requirements of Section 7.7. This evaluation using the linearity check data is optional.
However, the interference checks under Section 7.7 are manditory for each test.


6.4 Stability Check. Conduct the following procedure once for the maximum nominal range
to be used on each electrochemical cell (NO, NO, and CO). After a stability check is
completed, it remains valid for five consecutive calendar days. After the five calendar day
period has elapsed, the stability check must be reaccomplished. Additionally, reaccomplish
the stability check if the cell is replaced or if a cell is exposed to gas concentrations greater
than 125 percent of the highest span gas concentration. (If the stack NO, concentration is less
than 5% of the stack NO concentration as determined using the emission test procedures under
Section 7, the NO, stability check is not required. However, the NO, cell shall be calibrated
in accordance with the manufacturer's instructions, the pretest calibration error check and post
test calibration calibration error check shall be conducted in accordance with Section 7, and
the test results shall be added to the NO test values to obtain a total NOx concentration.)


6.4.1 Stability Check Procedure. Inject the span gas for the maximum nonimal range to be
used during the emission testing into the analyzer and record the analyzer response at least
once per minute until the conclusion of the stability check. One-minute average values may be
used instead of instantaneous readings. After the analyzer response has stabilized, continue to
flow the span gas for at least a 30-minute stability check period. Make no adjustments to the
analyzer during the stability check except to maintain constant flow. Record the stability time
as the number of minutes elapsed between the start of the gas injection and the start of the 30-
minute stability check period. As an alternative, if the concentration reaches a peak value
within five minutes, you may choose to record the data for at least a 15-minute stability check
period following the peak.


6.4.2 Stability Check Calculations. Determine the highest and lowest concentrations
April 2 1, 1999                                                                               Page 13
State of Wvoming Portable Analvzer Monitoring Protocol

recorded during the 30-minute period and record the results on Form B. The absolute value of
the difference between the maximum and minimum values recorded during the 30-minute
period must be less than 3.0 percent of the span gas concentration. Alternatively, record
stability check data in the same manner for the 15-minute period following the peak
concentration. The difference between the maximum and minimum values for the 15-minute
period must be less than 2.0 percent of the span gas concentration.


7. EMISSION TEST PROCEDURES. Prior to performing the following emission test
procedures, calibratelchallenge all electrochemical cells in the analyzer in accordance with the
manufacturer's instructions.


7.1 Selection of Sampling Site and Sampling Points.


7.1.1 Reciprocating Engines. Select a sampling site located at least two stack diameters
downstream of any disturbance (e-g., turbocharger exhaust, crossover junction, or
recirculation take-offs) and one half stack diameter upstream of the gas discharge to the
atmosphere. Use a sampling location at a single point near the center of the duct.


7.1.2 Combustion Turbines. Select a sampling site and sample points according to the
procedures in 40 CFR 60, Appendix A, Method 20. Alternatively, the tester may choose an
alternative sampling location andlor sample from a single point in the center of the duct if
previous test data demonstrate the stack gas concentrations of CO, NO,, and 0, do not vary
significantly across the duct diameter.


7.1.3 BoilersIProcess Heaters. Select a sampling site located at least two stack diameters
downstream of any disturbance and one half stack diameter upstream of the gas discharge to
the atmosphere. Use a sampling location at a single point near the center of the duct.


April 21, 1999                                                                              Page 14

     am
7.2 W r Up Period. Assemble the sampling system and allow the analyzer and sample
interface to warm up and adjust to ambient temperature at the location where the stack
measurements will take place.


7.3 Pretest Calibration Error Check. Conduct a zero and span calibration error check
before testing each new source. Conduct the calibration error check near the sampling
location just prior to the start of an emissions test. Keep the analyzer in the same location
until the post test calibration error check is conducted.


7.3.1 Scrubber Inspection. For analyzers that use an external interference gas scrubber
tube, inspect the condition of the scrubbing agent and ensure it will not be exhausted during
sampling. If scrubbing agents are recommended by the manufacturer, they should be in place
during all sampling, calibration and performance checks.


7.3.2 Zero and Span Procedures. Inject the zero and span gases using the calibration
assembly. Ensure the calibration gases flow through all parts of the sample interface. During
this check, make no adjustments to the system except those necessary to achieve the correct
calibration gas flow rate at the analyzer. Set the analyzer flow rate to the value recommended
by the analyzer manufacturer. Allow each reading to stabilize before recording the result on
Form C. The time allowed for the span gas to stabilize shall be no'less than the stability time
noted during the stability check. After achieving a stable response, disconnect the gas and
briefly purge with ambient air.


7.3.3 Response Time Determination. Determine the NO and CO response times by
observing the time required to respond to 95 percent of a step change in the analyzer response
for both the zero and span gases, Note the longer of the two times as the response time. For
the NO, span gas record the time required to respond to 90 percent of a step change.


April 21, 1999                                                                             Page 15
State of Wyominp: Portable Analyzer Monitoring Protocol

7.3.4 Failed Pretest Calibration Error Check. If the zero and span calibration error check
results are not within the specifications in Section 4, take corrective action and repeat the
calibration error check until acceptable performance is achieved.


7.4 NO Cell Temperature Monitoring. Record the initial NO cell temperature during the
pretest calibration error check on Form C and monitor and record the temperature regularly (at
least once each 7 minutes) during the sample collection period on Form D. If at any time
during sampling, the NO cell temperature is 85 degrees F or greater and has increased or
decreased by more than 5 degrees F since the pretest calibration, stop sampling immediately
and conduct a post test calibration error check per Section 7.6, re-zero the analyzer, and then
conduct another pretest calibration error check per Section 7.3 before continuing. (It is
recommended that testing be discontinued if the NO cell exceeds 85 degrees F since the design
characteristics of the NO cell indicate a significant measurement error can occur as the
temperature of the NO cell increases above this temperature. From a review of available data,
these errors appear to result in a positive bias of the test results.)


Alternatively, manufacturer's documentation may be submitted showing the analyzer is
configured with an automatic temperature control system to maintain the cell temperature
below 85 degrees F (30 degrees centigrade) and provides automatic temperature reporting any
time this temperature is exceeded. If automatic temperature control/exceedance reporting is
used, test data collected when the NO cell temperature exceeds 85 degrees F is invalid.


7.5 Sample Collection. Position the sampling probe at the first sample point and begin
sampling at the same rate used during the calibration error check. Maintain constant rate
sampling (& 10 percent of the analyzer flow rate value used in Section 7.3.2) during the entire
test. Sample for an equal period of time at each sample point. Sample the stack gas for at
least twice the response time or the period of the stability time, whichever is greater, before
collecting test data at each sample point. A 21 minute period shall be considered a test for
April 21, 1999                                                                              Page 16
State of Wvominp Portable A n a l m Monitoring Protocol

each source. When sampling combustion turbines per Section 7.1.2, collect test data as
required to meet the requirements of 40 CFR 60, Appendix A, Method 20. Data collection
should be performed for an equal amount of time at each sample point and for a minimum of
21 minutes total. The concentration data must be recorded either (1) at least once each
minute, or (2) as a block average for the test using values sampled at least once each minute.
Do not break any .seals in the sample handling system until after the post test calibration error
check (this includes opening the moisture removal system to drain condensate).


7.6 Post Test Calibration Error Check. Immediately after the test, conduct a zero and span
calibration error check using the procedure in Section 7.3. Conduct the calibration error
check at the sampling location. Make no changes to the sampling system or analyzer
calibration until all of the calibration error check results have been recorded. If the zero or
span calibration error exceeds the specifications in Section 4, then all test data collected since
the previous calibration error check are invalid. If the sampling system is disassembled or the
analyzer calibration is adjusted, repkt the pretest calibration error check before conducting the
next test.


7.7 Interference Check. Use the post test calibration error check results and average
emission concentrations for the test to calculate interference responses (I,, and ko)for the CO
and NO cells. If an interference response exceeds 5 percent, all emission test results since the
last successful interference test for that compound are invalid.

7.8 Re-Zero. At least once every three hours, recalibrate the analyzer at the zero level
according to the manufacturer's instructions and conduct a pretest calibration error check
before resuming sampling. If the analyzer is capable of reporting negative concentration data
(at least 5 percent of the span gas below zero), then the tester is not required to re-zero the
analyzer.

protocol.

ppm CO to the NO and NO, span gases and the analyzer response in ppm NO to the NO, span
gas. Calculate the CO and NO interference responses using the equations under Sections 7.7.1
and 7.7.2, respectively, and estimated stack gas CO, NO and NO, concentrations.


8.2 Stability Check Data. Record the analyzer response at least once per minute during the
stability check under Section 6.4.1. Use Form B for each pollutant (NO, NO,, and CO).
One-minute average values may be used instead of instantaneous readings. Record the
stability time as the number of minutes elapsed between the start of the gas injection and the
start of the 30-minute stability check period. If the concentration reaches a peak value within
five minutes of the gas injection, you may choose to record the data for at least a 15-minute
stability check period following the peak. Use the information recorded to determine the
analyzer stability under Section 6.4.2.


8.3 Pretest Calibration Error Check Data. On Form C, record the analyzer responses to
the zero and span gases for NO, NO,, CO, and 0, injected prior to testing each new source.
Record the calibration zero and span gas concentrations for NO, NO,, CO, and 0,. Record
the absolute difference between the analyzer response and the calibration gas concentration,
divide by the span gas concentration, and multiply by 100 to obtain the percent of span.
Record whether the calibration is valid by comparing the percent of span with the
specifications under Section 4.1 for the zero calibrations and Section 4.2 for the span
calibrations. Record the response times for the NO, CO, and NO, zero and span gases as
described under Section 7.3.3. Select the longer of the two times for each pollutant as the
response time for that pollutant. Record the NO cell temperature during the pretest
calibration.

8.4 Test Data. On Form D-1, D-2, or D-3, record the source operating parameters during
the test. Record the test start and end times. Record the NO cell temperature after one third
of the test (e.g., after seven minutes) and after two thirds of the test (e.g., after 14 minutes).
From the analyzer responses recorded each minute during -the test, obtain the average flue gas
concentration of each pollutant. These are the uncorrected test results.


8.5 Post Test Calibration Error Check Data. On Form C, record the analyzer responses to
the zero and span gases for NO, NO,, CO, and 0, injected immediately after the test. To
evaluate any interferences, record the analyzer responses in ppm CO to the NO and NO, span
gases and the analyzer response in ppm NO to the NO, span gas. Record the calibration zero
and span gas concentrations for NO, NO,, CO, and 0,. Record the absolute difference
between the analyzer response and the calibration gas concentration, divide by the span gas
concentration, and multiply by 100 to obtain the percent of span. Record whether the
calibration is valid by comparing the percent of span with the specifications under Section 4.1
for the zero calibrations and Section 4.2 for the span calibrations. (If the pretest and post test
calibration error check results are not within the limits specified in Sections 4.1 and 4.2, data
collected during the test is invalid and the test must be repeated.) Record the NO cell
temperature during the post test calibration. Calculate the average of the monitor readings
during the pretest and post test calibration error checks for the zero and span gases for NO,
NO,, CO, and 0,. The pretest and post test calibration error check results are used to make
the calibration corrections under Section 9.1. Calculate the CO and NO interference responses
using the equations under Sections 7.7.1 and 7.7.2, respectively and measured stack gas CO,
NO and NO, concentrations.


8.6 Corrected Test Results. Correct the test results using the equation under Section 9.1.
Add the corrected NO and NO, concentrations together to obtain the corrected NOx
concentration. Calculate the emission rates using the equations under Section 10 for
comparison with the emission limits. Record the results on Form D-1, D-2, or D-3. Sign the
