**Pre-Audit Preparation Checklist**

> **1. Electronic Data Review**
>
> a\. [Quarterly Feedback Reports]{.underline}
>
> Review ETS feedback report. Download from the EPA mainframe (if you
> have access rights) or you can request a copy of the feedback from
> your CAMD contact. Also obtain a copy of the MDC feedback report
> available from your CAMD contact.
>
> b\. [Using MDC Software]{.underline}

1.  Print out a copy of Monitoring Plan from the MDC software to bring
    with you to the plant.

2.  Generate and review MDC QA test evaluation reports. Also look for
    repeated QA tests during a quarter.

3.  Print out a copy of electronic RATA and linearity reports for
    comparison with on-site hard copy data.

4.  Review exemption and grace period reports.

5.  Review reports of recertification events and, if submitted, of
    missing data events.

6.  Use MDC Hourly to check hourly calculations and missing data
    periods.

7.  Use MDC Hourly graphing functions to chart emission trends for
    comparison to monitor spans, and for unusual data trends (abrupt
    changes or constant emission rate).

> **2. Hard Copy File Review**

a.  Review correspondence, petitions, and previous audit/inspection
    reports.

b.  If available, compare hard copy linearity test and RATA reports to
    the electronic reports in MDC. Also review the hard copy RATA test
    report with a focus on reference method documentation that can not
    be checked electronically with MDC.

c.  Check that the unit has the required Acid Rain or operating permit.

| Displays will vary by       |                                        |
| analyzer, so ask the source |                                        |
| what the displays are and   |                                        |
| what they mean.             |                                        |

| and compare to the          |                                        |
| monitoring plan. Has the    |                                        |
| source done the annual      |                                        |
| span/range check required   |                                        |

+-----------------------------+----------------------------------------+

**4. Dilution Air Systems (Including Air Cleaning Subsystem)**

  -----------------------------------------------------------------------
  **What to Check**              **Observations**
  ------------------------------ ----------------------------------------
  Has the **dilution probe       
  orifice** been changed? If the 
  orifice has been changed, ask  
  if there is a procedure for    
  changing the orifice in the    
  QA/QC Plan, what prompts a     
  change, and how the dilution   
  ratio is verified.             

  Is the **dilution probe        
  ejector pump vacuum** at or    
  below the certification value? 
  How often is it checked?       

  What is the **dilution         
  ratio**? Check the **dilution  
  air and analyzer flow          
  settings**. How are these set  
  and verified? These should all 
  be described in the QA/QC      
  plan.                          

  Are **correction factors**     
  applied to the dilution ratio  
  for changes in pressure,       
  temperature, or molecular      
  weight? Have these been        
  changed since the last RATA?   
  Changes to correction factors  
  should be recorded in the      
  maintenance log,. QA testing   
  may also be required . (Also   
  see Table 8 - DAHS).           

  Check the **inlet and outlet   
  pressures of CO~2~ air cleaner 
  filter**. Compare levels to    
  the QA/QC Plan.                

  How often are the **air        
  cleaning filters and drying    
  agents replaced**? Compare to  
  the QA/QC plan.                
  -----------------------------------------------------------------------

**5. Source Level Extractive Systems**

  -----------------------------------------------------------------------
  **What to Check**              **Observations**
  ------------------------------ ----------------------------------------
  Check the **umbilical lines**  
  entering the CEMS shelter for  
  condensation (visible water    
  drops).                        

  For a dry system using         
  chillers check the **chiller   
  temperature**. What is the     
  proper temperature range, and  
  how often is it verified?      
  Compare against the QA/QC      
  Plan.                          
  -----------------------------------------------------------------------

**6. Analyzers**

  ------------------------------------- ---------------------------------
  **What to Check**                     **Observations**

  Ask the source if there have been any 
  changes since the last audit or       
  **certification/recertification.**    
  Document the serial numbers and       
  compare to those in the monitoring    
  plan.                                 

  What is the status of the **control   
  panel lights, indicators and          
  alarms**? Displays will vary by       
  analyzer, so ask the source what the  
  displays are and what they mean.      

  Check **range settings**, and compare 
  to the monitoring plan. Has the       
  source done the annual span/range     
  check required by App. A?             

  Compare the **sample flow rate,** if  
  displayed by a rotameter (or a        
  digital reading), to the QA/QC Plan.  

  Have there been any changes to        
  **correction factors** (NO~x~         
  quenching and moisture monitors)      
  since the last RATA? Changes to       
  correction factors should be recorded 
  in the maintenance log, and the QA/QC 
  Plan should outline the procedures    
  for changing the correction factors   
  (Appendix B, Section 1.1.3). QA       
  testing may also be required (See     
  \'75.20(b), and Recertification and   
  Diagnostic Testing Policy).

| to verify that hard copy and        |                                |
| electronic data match. Check that   |                                |

**9**. **Optional Control Equipment Parameter Monitoring (\' 75.34)**

  -----------------------------------------------------------------------
  **What to Check**                     **Observations**
  ------------------------------------- ---------------------------------
  Check the QA/QC Plan which will       
  identify add-on **SO~2~ or NO~x~      
  control equipment parameters and      
  acceptable ranges** if the source is  
  using add-on control equipment        
  missing data options. Parameters and  
  acceptable ranges are required by App 
  B, \' 1.1.1.                          

  Review **control equipment parameter  
  monitoring records** for a number of  
  missing data periods. Compare the     
  parameter data to the acceptable      
  ranges in the QA/QC Plan. Identify    
  any periods when the range is         
  exceeded and how the missing data     
  period was flagged in the DAHS        
  (control operating properly or not    
  operating properly).                  

  Ask the source how it enters proper   
  control equipment operation for       
  missing data periods into the         
  **DAHS**. Manual entry of missing     
  data period information is allowed by 
  Part 75.                              
  -----------------------------------------------------------------------

**10. Maintenance Log Review**

  -----------------------------------------------------------------------
  **What to Check**                     **Observation**
  ------------------------------------- ---------------------------------
  Do the **log entries** sufficiently   
  describe the action taken? Are the    
  entries understandable?               

  Does the log show **maintenance       
  checks** at the frequency identified  
  in the QA/QC Plan? Are all records    
  available (see Table C)?              

  Identify **recurring failures or      
  malfunctions** recorded in the log.   

  Are **malfunctions resolved** as      
  specified in the QA/QC Plan?          

  Do events in the maintenance log      
  correspond to reported **missing data 
  periods** in the quarterly reports?   

  Are there **repeated adjustments** to 
  the zero or span?                     

  Have system parts or components been  
  replaced? If so has the proper        
  **recertification or diagnostic       
  testing** been performed?             

  Does the log show any **pre-RATA      
  adjustments?**                        
  -----------------------------------------------------------------------

**Table C:**

**Maintenance Record Requirements (Appendix B \' 1.1.3)**

  -----------------------------------------------------------------------
  **The following records are required by the QA/QC Plan provisions of
  Part 75:**

  ! date, time, and description of any testing, adjustment, repair,
  replacement, or preventive maintenance action performed on any
  monitoring system.

  ! records of any corrective actions associated with a monitor=s outage
  period.

  ! any adjustment that changes a system=s ability to record and report
  emissions data (e.g., changing of flow monitor or moisture monitoring
  system polynomial coefficients, K factors or mathematical algorithms,
  changing of temperature and pressure coefficients and dilution ratio
  settings)**.**

  ! a written explanation of the procedures used to make the
  adjustment(s) shall be kept.

| performance test? A NO~x~ converter       |                          |
| efficiency test is required if the NO~2~  |                          |
| concentration is greater than 5 ppm. The  |                          |

| Check the results of the **pretest        |                          |
| linearity check** of the reference method |                          |

| Difference between the calibration gas    |                          |
| value and response should be within 2% of |                          |
| the span for the linearity test.          |                          |
| Otherwise the test is repeated until      |                          |
| passed. No adjustments can be made to the |                          |
| analyzer after the linearity check.       |                          |
+-------------------------------------------+--------------------------+
| Record and check the **span** of the      |                          |
| reference method analyzers. A test run is |                          |
| invalid if a measured concentration       |                          |
| exceeds the span. (Method 6C, Sec. 2.1)   |                          |

| and after each run that you observe (Use  |                          |
| Table in 4). The response should be       |                          |
| stable before it is recorded. For         |                          |
| bias/drift checks the sampling system     |                          |
| bias must be within 5% of the span, and   |                          |
| the calibration drift must be within 3%   |                          |
| of span.                                  |                          |

**5. Reference Method Calculations**

  -----------------------------------------------------------------------
  For sampling run durations of less than 1 hour, measurements at
  1-minute intervals or a minimum of 30 measurements, whichever is less
  restrictive, shall be used.

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

**a. Percent by volume**

  -----------------------------------------------------------------------------------------------------
  Use equation 6C-1 from Method 6C to calculate the run percent by volume (ppm or %)

  $$C_{\text{gas}}\text{ = }(\overline{C}\text{ - }C_{o})\frac{C_{\text{ma}}}{C_{m}\text{ - }C_{o}}$$

  C~gas~ = Effluent gas concentration, dry basis, ppm.

  C~avg~ = Average gas concentration indicated by gas analyzer, dry basis, ppm or %.

  C~o~ = Average of initial and final system calibration bias check responses for the zero gas, ppm, or
  %

  C~m~ = Average of initial and final system calibration bias check responses for the upscale
  calibration gas, ppm or %.

  C~ma~ = Actual concentration of the upscale calibration gas, ppm or %.
  -----------------------------------------------------------------------------------------------------

**b. Percent by volume (O~2~ with low-level calibration gas)**

+-----------------------------------------------------------------------+
| For O~2~ analyzers that use a low-level calibration gas in place of a |
| zero gas, calculate the effluent gas concentration using Equation     |
| 3A-1.                                                                 |
+-----------------------------------------------------------------------+
| C~ma~ - C~oa~                                                         |
|                                                                       |
| C~gas~ = CCCCCCCCC (¯ - C~m~) + C~ma~ Eq. 3A-1                        |
|                                                                       |
| C~m~ - C~o~                                                           |
+-----------------------------------------------------------------------+
| C~ma~ = Actual concentration of the upscale calibration gas, percent  |
+-----------------------------------------------------------------------+
| C~oa~ = Actual concentration of the low-level calibration gas,        |
| percent.                                                              |
+-----------------------------------------------------------------------+
| C~m~ = Average of initial and final system calibration bias check     |
| responses for the upscale calibration gas, percent.                   |
+-----------------------------------------------------------------------+
| C~o~ = Average of initial and final system calibration bias check     |
| responses for the low level gas, percent.                             |
+-----------------------------------------------------------------------+
| ¯ = Average gas concentration indicated by the gas analyzer, dry      |
| basis, percent.                                                       |

**c. NOx lbs/mmBtu Calculation**

  ------------------------------------------------------------------------------------------------
  **O~2~ Diluent -** When the NO~x~ continuous emission monitoring system uses O~2~ as the
  diluent, and measurements are performed on a dry basis, use the following conversion procedure

  $$\text{E = K }C_{h}\text{ F }\frac{\text{20}\text{.}9}{\text{20}\text{.}\text{9 - \%}O_{2}}$$

  When measurements are performed on a wet basis, use the equations in method 19 in appendix A of
  part 60.

  **CO~2~ Diluent** - When the NO~x~ continuous emission monitoring system uses CO~2~ as the
  diluent, use the following conversion procedure:

  $$\text{E = K }C_{h}F_{c}\frac{\text{100}}{\text{\%}\text{CO}_{2}}$$

  When CO~2~ and NO~x~ measurements are performed on a different moisture basis, use the equations
  in method 19 in appendix A of part 60.

  **Where:**

  E = Pollutant emissions during unit operation, lb/mmBtu

  K = 1.194  10^‑7^ (lb/dscf)/ppm NO~x~.

  C~h~ = Hourly average pollutant concentration during unit operation, ppm.

  %O~2~, %CO~2~ = Oxygen or carbon dioxide volume during unit operation (expressed as percent O~2~
  or CO~2~).

  F, F~c~ = a factor representing a ratio of the volume of dry flue gases generated to the caloric
  value of the fuel combusted (F), and a factor representing a ratio of the volume of CO~2~
  generated to the calorific value of the fuel combusted (F~c~), respectively.

| fuel flow meters to those           |                                |
| identified in the monitoring plan.  |                                |
| Replaced fuel flow meters require   |                                |
| recertification.                    |                                |

**4. DAHS Checks**

  -------------------------------------- --------------------------------
  **Fuel Flowmeter Checks**              **Observations**

  Check the **current DAHS version**     
  against the monitoring plan, and check 
  records confirming that DAHS           
  verification tests were conducted for  
  the missing data routines. The latest  
  test should have occurred no earlier   
  than when the unit began using EDR     
  v2.1 (or v2.2, when applicable).       

  How are **missing data period data**   
  entered into the DAHS? If entered by   
  hand, spot check the data with         
  supporting hardcopy information.

**2. QA/QC Operating Parameters**

  ----------------------------------------------------------- ------------------
  **What to Check**                                           **Observations**

  Check and record the recommended **range of QA/QC           
  parameters** in the QA/QC plan. There should be at least 4  
  parameters for turbines or reciprocating engines, and       
  oxygen for boilers. (Appendix E, \' 2.3.2).                 

  Spot check the **hourly parameter records** to identify any 
  parameter deviation periods. Ask that the electronic data   
  for that period be brought up on the DAHS to verify that    
  the electronic data correctly identified a missing data     
  period.                                                     

  Also request that the source identify any parameter         
  deviations, and ensure that proper **missing data           
  procedures** are used for those hours. The source is        
  required to redetermine the Appendix E correlation if a     
  single deviation period exceeds 16 operating hours          
  ----------------------------------------------------------- ------------------

**3. NO~x~ Emission Rate Testing**

  ----------------------------------------------------------- ------------------
  **What to Check**                                           **Observations**

  Check that the **test procedures** are described in the     
  QA/QC plan. This is a required component of the QA/QC plan. 
  The procedures should match the test requirements in        
  Appendix E, \' 2.1.                                         

  If not done prior to the visit, check hardcopy test results 
  to **verify that fuels, loads, and NO~x~ rates** match      
  those reported electronically in the EDR monitoring plan.   
  (Use MDC to print out a copy of the monitoring plan prior   
  to your visit.)

**Sample Standard Operating Procedure**

> **Planning and Performing a Part 75 Linearity Test\***
>
> **[Pre- Audit Survey]{.underline}**:
>
> In preparation for the performance of a linearity test, it is
> important that the following information be obtained through a phone
> call to the facility\'s environmental coordinator:
>
> 1\. How close (in feet) is it possible to back the test trailer to a
> point that can be used to introduce the test gases to the CEMS?
> \[Usually a point near the daily calibration gases for the unit.\]
>
> 2\. Can connection to the CEMS calibration sample injection point be
> made through the use of 1/4@ swagelock nut fitting? If not what type
> of connector is required?
>
> 3\. What is the normal sample flow rate to the analyzers at the sample
> point? \[That is, what are the flow rates used to perform the daily
> calibrations? What sample flow rates are used to perform the quarterly
> linearities?\] OR, what is the usual sample delivery pressure used in
> conducting the quarterly linearities or daily calibrations?
>
> 4\. What are the span values for the NO~x~, SO~2~, and CO~2~ monitors
> to be evaluated?
>
> 5\. Is the CEMS a dilution or source level extractive system? Are
> single or multiblend gases typically used for daily calibrations?
>
> 6\. What is the normal response time experienced when the facility
> runs its quarterly linearities?
>
> 7\. What additional safety requirements might be of concern in the

>
> **[Pre-Audit Preparation]{.underline}**:
>
> 10\. Select the proper gases to perform the audit based on the span
> values for the monitors to be evaluated. Gas values for each pollutant
> must be selected such that a low range gas of 20% - 30% of the span
> value, a mid range gas of 50% - 60% of the span value, and a high
> range gas of greater than 80% of span are selected.
>
> 11\. Make sure that each of the cylinders have not expired, and obtain
> a copy of each of the certification sheets.
>
> 12\. Check that the cylinder cap is not stuck and that it will be
> possible to remove it easily in the field.
>
> 13\. For each gas loaded into the audit trailer keep the cylinder
> certification sheets in a folder to be placed in the cab of the truck
> and a log sheet summarizing the contents and concentrations of each
> cylinder.
>
> 14\. Select the proper regulator for each of the cylinders to be used.
>
> 14.a Identify the regulator. Check the label and the inlet and outlet
> gauges. Ascertain that the high-pressure gauge is suitable for the
> pressure of the cylinder value outlet.
>
> 14.b Inspect the regulator. Check the regulator for evidence of damage
> or contamination. If there is any evidence of physical damage, or
> foreign material inside the regulator, contact the customer service
> representative for return or repair information.
>
> 15\. Gather all equipment needed for performing the audit.
>
> 16\. Check the condition of the tires on the audit trailer and inspect
> the tow vehicle prior to departure. Check for tire pressures,
> condition, oil level, belt conditions, etc.
>
> 17\. At the appropriate facility (such as a calibration test equipment
> center), attach the regulators to each cylinder to check the cylinder
> tank pressures. If any tank has a pressure less than 700 psi it should
> not be used for the linearity test audit.
>
> **[Pre-Inspection Meeting]{.underline}**:
>
> During the pre-inspection meeting, review the test procedure and
> address any special circumstances of safety issues for working in the
> designated area for that day.
>
> **[Setup]{.underline}**:
>
> 18\. Back the trailer into position.
>
> 19\. Open the tail gate.
>
> 20\. Uncap the cylinder gases.
>
> 21\. Attach the regulators.
>
> 21.a. Inspect the regulator. Check the regulator for evidence of
> damage or contamination. If there is any evidence of physical damage,
> or foreign material inside the regulator, do not use the regulator for
> the test.
>
> 21.b. Inspect the cylinder valve. Check the cylinder valve for
> evidence of damage or contamination. Remove any foreign material
> before attaching the regulator.
>
> 21.c. Attach the regulator. Fasten the regulator to the cylinder and
> tighten the inlet nut securely. (Do not over tighten the inlet nut or
> damage to the threads may occur)
>
> 21.d. Close the regulator. To close the regulator turn the adjusting
> knob to the full counter-clockwise position. The regulator must be
> closed before opening the cylinder valve.
>
> 21.e. With the regulator adjusting knob turned fully
> counter-clockwise, place both hands on the cylinder valve and open it
> slowly, allowing the pressure to rise gradually in the regulator.
> Stand as shown (see figure) with the cylinder valve between you and
> the regulator. Never stand in front of the adjusting knob.
>
> 21.f. When the high-pressure gauge indicates maximum pressure, open
> the cylinder valve fully.

22\. Connect each regulator to the gas delivery manifold.

> 23\. Connect the gas delivery manifold to the gas delivery line and
> have plant personnel attach the line to the CEMS system at the proper
> injection point. The injection point should direct the cylinder gases
> through all components of the sampling system and conditioning
> systems.
>
> **[Linearity Test Procedure]{.underline}**:
>
> 24\. Start the flow of the low range gas to the system at a rate equal
> to the rate normally used to perform linearities and daily
> calibration.
>
> 25\. Wait for the readings on the analyzer(s) to become stable.
>
> 26\. Record the concentration displayed by the analyzer.
>
> 27\. Repeat Steps 24 - 26 for the mid range gas.
>
> 28\. Repeat Steps 24 - 26 for the high range gas.
>
> 29\. Repeat Steps 24 - 28 for Run 2
>
> 30\. Repeat Steps 24 - 28 for Run 3
>
> 31\. Repeat Steps 24-30 for each gas monitor to be evaluated.
>
> 32\. Using the Linearity Test Audit spreadsheet calculate the average
> percentage error at each gas concentration level for each gas tested.
>
> 32.a. The error in linearity for each calibration gas concentration
> (low-, mid-, and high-levels) shall not exceed or deviate from the
> reference value by more than 5.0 percent as calculated by the
> equation:
>
> LE=(\|R-A\|/R)\*100% , or
>
> 32.b. The absolute value of the difference between the average of the
> monitor response values and the average of the reference values,
> \|R-A\| shall be less than or equal to 0.5 percent CO~2~ or O~2~,
> whichever is less restrictive.
>
> 33\. The linearity requirements are located in 40 CFR 75, Appendix A.
>
> **[Packing up]{.underline}**:
>
> 34\. Have the plant personnel detach the line from the CEMS injection
> point. Disconnect the gas delivery manifold from the gas delivery line
> and pack the delivery line.

35\. Detach the regulators as follows:

> 35.a Close the cylinder valve.
>
> 35.b. Vent the gas in the regulator by turning the adjusting knob
> clockwise so that no pressure is trapped inside the regulator.
>
> 35.c Close the regulator. After relieving all the gas pressure, turn
> the adjusting knob counterclockwise as far as it will go.
>
> 35.d Disconnect each regulator from the gas delivery manifold.
>
> 35.e. Disconnect the regulator.
>
> 35.f. Protect the regulator by packing it so that the fittings will
> not be exposed to dirt, contamination, or mechanical damage.
>
> 35.g. Replace the cylinder valve cap.

**[Post-Inspection Meeting]{.underline}**:

During the post-inspection meeting, review the test result and make a
printout of the data and results obtained from the linearity to give to
the source.
