- 1 2.0 Summary of Results
AST conducted emission testing on two ( 2 ) 4

- stroke lean burn compressor engines at a PTC facility in Mississippi

. Testing was conducted February 25

– 26
, 20 10

. Table s 2

- 1 and 2

- 2 provide a summary of the testing results

. Any difference between the summary results listed in the following table s and the detailed results contained in the appendices is due to rounding for presentation.

Ent halpy Analytical provided the Method 320 formaldehyde concentration as measured, which is the standard reporting method, and adjusted based on the spike recovery for each unit. Tables 2

- 1 and 2

- 2 contain concentrations and emission rates using both report ed values.

After reviewing analytical data for Unit 1, there was an apparent sampling or sample recovery issue with the Run 1 primary train. The Run 1 results listed in Table 2

- 1 were calculated using data collected with the duplicate train. Two (2) set s of duplicates were analyzed for each Unit and data for the other three (3) runs is listed below.

 Unit 1, Run 2 18.8% difference

 Unit 2, Run 1 3.3% difference

 Unit 2, Run 2 6.6% difference

Stack gas moisture content s w ere measured in the field using the Method 323 sampling train s . Due to the small volume of gas that was sampled, the analyses produced a significant positive bias. F or converting Method 320 formaldehyde concentrations from a wet to dry basis , the gas moisture contents were calculated u sing stoichiometric combustion equations and adjusting for the ambient humidity

3.8 Quality Assurance/Quality Control

– U. S. EPA Ref erence Test Methods 3A, 7E and 10
EPA Protocol 1 Calibration Gases

– Cylinder calibration gases were supplied by NexAir which meet EPA Protocol 1 (+/

- 2%) standards.

Calibration/Bias/Drift

– Each instrument was calibrated directly with zero nitrogen, mid

- level and high

- level (span) gases prior to initiating testing each day and additional calibrations performed as needed. Pretest Bias checks were also performed prior to initiating testing by introducing zero and mid level gases through the sampling system

. Posttest Bias and Drift checks were performed after each test run by introducing zero and mid level gases through the sampling system.Pipeline Transmission Company Emissions Test Report Testing Methodology

Page 3

- 3 A calibration gas dilution system field check was conducted in accordance with EPA Method 205 by diluting a high

conc entration Protocol 1 gas with Zero Nitrogen to 50%, 30%, and 10% of the cylinder gas concentration. The three (3) ranges of diluted calibration gases were sent directly to the analyzer, and the analyzer response was recorded in
an electronic field data sh eet. The analyzer response agreed within 2% of the actual diluted gas concentration. A second Protocol 1 calibration gas, with a cylinder concentration within 10% of one of the gas divider settings described above, was introduced directly to the analyzer , and the analyzer response was recorded in an electronic field data sheet. The cylinder concentration and the analyzer response agreed within 2%. These steps were repeated three (3) times. Copies of the Method 205 data can be found in the Quality Assur ance/Quality Control Appendix.

An NO 2 – NO converter check was performed on the CAI Model 400CLD NOx analyzer prior to initiating emission testing. An approximately 50 ppm nitrogen dioxide cylinder gas was introduced directly to the NOx analyzer and
the instrument response was recorded on an electronic data sheet. The instrument response was within +/

- 10 percent of the cylinder concentration.

Data Collection

– PM Plus Data Acquisition System (Dutech Analog Signal Modules) with battery backup was used to record the instrument response (analog 0

- 10 volt signal) in one (1) minute averages. The data was continuously stored as a *.CSV file in Excel format on the hard drive of a desktop computer. At the completion of the emission testing the data was also saved to disk.

# FTIR Narrative Summary

# Enthalpy Analytical Narrative Summary

Introduction

Jordan Laster of Enthalpy Analytical, Inc. and Alliance Source Testing staff performed Fourier Transform Infrared (FTIR) Spectroscopy testing on Thursday, February 25 through Friday February 26

. at the Columbia Gulf Tran smission facility in Corinth, Mississippi. Four one-hour test runs for formaldehyde (HCHO) were conducted at the outlet of Unit 01, and three one-hour test runs were conducted at the outlet of Unit 02. Alliance Source Testing (Alliance) of Decatur, Alabama retained Enthal py Analytical, Inc. of Durham, North Carolina (Enthalpy) to operate the FTIR instrument and analyze the data. Testing was based on the procedures outlined in EPA Method 320.



## Results

Formaldehyde was detected at an average con centration of approximately 24.5 ppm (wet) at Unit 01, and 29.1 ppm (wet) at Unit 02. Alt hough Method 320 does not address adjustment of results based on spike recoveries, a second summary has been included which takes the spike bias on each unit into account. These results may be more representative of the actual matrix within the sources. (See Quality Assurance Section Matrix Spikes for additional information.)


## FTIR Extractive Sampling System

Sample gas was extracted through probe assembly and heat-traced lines and into the absorption cell of the FTIR spectrometer. Th e heat-traced lines were maintained at approximately 250o F. A pump connected to the FTIR cell outlet drew sample gas through the cell at a flow rate of approximately ten liters per minute. The absorption cell was maintained at 121o C to prevent condensation in the cell and minimize analyte adhe sion to the walls and mirrors of the cell. The absorption cell path length was determined using a certified cylinder of ethylene sent directly to the FTIR spectrometer. Results of the path length calculations are presented in the “FTIR QA” Section of this report.



## FTIR Instruments

The FTIR instrument used for this test wa s MIDAC Series I medium-resolution Michelson interferometer spectrometer, designated “T1.” Th e interferometer and detector were assembled by MIDAC Corporation (Costa Mesa, California). Th e nominal spectral resolution of the system was one half wavenumber (0.5 cm -1 

### ). The instrument was equipped with a nominal 10-meter path length White cell, and zinc selenide (ZnSe) beamsplitter and windows. Instrument T1 was equipped and an indium antimonide (InSb) liquid n itrogen-cooled detector. The inside walls of the cell were polished stainless steel to minimize interaction of the sample with the cell walls, and the cell mirrors were of bare gold. The gas pr essure in the FTIR sample cell was monitored with a pressure transducer connected directly to the sample cell. The heated sample cell was wrapped in an insulating blanket and the temper ature was controlled with type J thermocouples. All connections in the sampling system were wrappe d with electric heat tape and/or insulated to eliminate “cold spots.” All components were constr ucted of Type 316 stainless steel, SilcoSteel

coated stainless steel, or Teflon. The absorption cell volume was approximately 1.9 liters.

The FTIR system was operated via portable comput er; a data archive storage system (USB Mass Storage Drive, 80 GB) was used for data backup. All interferograms, single beams, absorbance spectra, and background single beams are stored and archived at Enthalpy Analytical, Inc.

## Gas Sample Collection

Nitrogen served as the background gas. For each day, sample gas was continuously purged through the sampling systems and absorption ce lls. On Unit 01, Spectra consisting of 32 coadded scans were recorded approximately once every 35 seconds; on Unit 02 Spectra consisting of 50 co-added scans were recorder approximately once every minute. Before, during, and after each test run, a certified calibration transfer sta ndard (CTS) gas of ethylene was introduced to the FTIR spectrometers and allowed to reach st eady state. The absorption path length results from these measurements are included in the “FTIR QA” section of this report.



## Data Collection

All spectra were recorded at a nominal resolution of 0.5 cm -1 

### . The absorption cell was configured to allow many passes of the infrared beam to traverse the cells between the entrance and exit windows. This provided for a path lengt h of approximately 10 meters. Sample spectra were divided point-by-point by 128-scan background spectra recorded using N 2 

### . The single

## Enthalpy Analytical Narrative Summary (continued)

beam spectrum was constantly monitored and a new background was generated when residual and absorbance spectra indicated component bu ild-up on the optical surfaces or alignmentrelated baseline shifts.


## Spectral Analyses

Enthalpy staff used the program AutoquantPro  (hereafter “AQ,” version 4.0.0.136,  Midac Corporation, 2007) to collect and analyze all the infrared field data. The program allows the development and storage of analytical “methods” for analysis of spectral data (absorbance) files; we developed three “methods” for the tasks of de termining the 1) absorption path length, 2) the concentration of the target compound HCHO, and 3) the concentrations of the surrogate spike compound methanol (MeOH) and the spike tracer compound (ethylene). All the information required to reproduce these analytical techniques is contained in the “Method Map” section of this report.

The concentration uncertainty reported by Autoqua ntPro is called the Standard Error of the Estimated Concentration, or SEC; it is also known as the Marginal Standard Deviation. The uncertainties in the concentration are proportiona l to the square root of the sums of the squares of the residual. After the residual spectrum is obtained, which we will call R

, 

### the error variance for the case of a single reference spectrum is calculated as:

where: n is the number of observations. The SEC is given by:

where: A is the spectrum and C is the known concentration of the reference.

The 95% confidence interval is 1.96 times the SEC.


## Spectra

The reference spectra used for these analyses were developed by Enthalpy Analytical, Inc., by the EPA, by the MIDAC Corporation, and by the Department of Energy / Pacific Northwest National Laboratory (DOE/PNNL). All spectra used in the analysis and the corresponding analytical regions are documented in the “Method Map” section of this report. For all data analysis, the apodization was triangular and the baseline correction was linear. All spectra were analyzed using temperature and pressure corrections.

Calibration Transfer Standards and Absorption Path Lengths



### Before and after each test run, a calibration tran sfer standard (CTS) gas (Custom Gas Solutions CC67207, 100 ppm Ethylene, balance N 2 

### ) was introduced to the FTIR system to determine the effective absorption path length. This determination was based on comparisons of the “field” CTS spectra to a laboratory CTS spectrum reco rded by MIDAC. Over the test period, all calculated absorption path lengths determined for the instrument varied by less than 3% of the mean path lengths.

Matrix Spikes



### Matrix spiking was performed at each source. Fo r all spikes, the spike gases consisted of a certified standard of formaldehyde (Spectra CC279093, 21.0 ppm formaldehyde, balance N 2 

### ) and a high-level ethylene cylinder (Custo m Gas Solutions XL001588B, 1000 ppm ethylene, balance N 2 

### ) was used as the tracer gas. A blended cylinder containing both the spike gas (Formaldehyde) and an appropriate tracer gas wa s not available for this test. We have a standard approach to spiking from two cylinders that is designed to meet the QA requirements of EPA Method 320. The spiking cylinder and the tracer gas cylinder are connected to the two unique ports of a three-way valve. The comm on port is connected to the inlet of a needle valve, the outlet of which is connected to the sp ike line. The gas cylinder regulators are set so that both are at the same pressure. The three- way valve is turned to allow the tracer gas to enter the system. The needle valve is then adju sted until the tracer returns at less than 10% of the tag value (Section 9.2.1 of EPA Method 320 specifies ≤ 10% of the flow rate, which equates to a 90% or greater dilution factor). Once the tracer is stable, the three-way valve is turned to the spike gas. The pressures and the n eedle valve ensure that the flow is identical to that of the tracer.

A complication in this case was that the tracer gas (1000ppm Ethylene cylinder, <100ppm with sample dilution) was not able to be clearly identified from the estimated 1,400-1,600 ppm methane in the sample stream, and an alternate appropriate tracer gas was not available on-site. The methane was causing near maximu m absorption in the wavelength range used for ethylene determination. The high erro r values as shown for the spike on the 25 th 

### show the low confidence in the calculation of the tracer for this spike. The ambient air spike performed on the 26 th 

### show good error values (low error) which helps to provide confidence in the spike calculation. This spike shows that the sampling system is properly delivering Formaldehyde.

Minimum Detectable Concentration (MDC)



### EPA Method 320 and the equivalent ASTM Standard D6348-03 specify a number of analytical uncertainty parameters that the an alyst may calculate to characterize the FTIR system performance. The reported MDC wa s calculated as three times the calculated concentration of formaldehyde when it was known that no formaldehyde was present.

## Enthalpy Analytical Narrative Summary (continued)

Spectral Interferences



### Enthalpy staff performed careful visual examinati ons of the sample spectra and the “residual” spectra generated by spectrally subtracting known compounds from the sample spectra. The goals of these examinations are 1) to confirm the accuracy of the reported analyte concentrations and 2) to detect any additional compounds that might have been present in the sample streams.

Data Storage


### A dedicated desktop computer controlled the FTIR spectrometer; the hard drive of the computer served as the primary data storage media. Duri ng testing, Enthalpy staff created and maintained backup and archive copies of the spectral data (interferograms, single beam spectra, and absorbance spectra) on USB memory devices.

Data Reviews


### Enthalpy subjects all the spectroscopic data and anal ytical results to several levels of review. First, the field instrument operator inspect s the instruments’ outputs to ensure their appropriate performance during the sampling runs . Second, an additional analyst who did not perform the analyses examines the sample spect ra and the quantitative analytical results, and also spot-checks the analysis results by hand; these examinations include visual comparisons of the sample and reference spectra such as those illustrated below in the “Selected Spectra” section. Finally, an independent reviewer checks the final report for consistency.

Custody Heather Tarjeft received the samples on 3/1/10 after being relinquished by Alliance Source Testing. The samp les were received at 6.0 oC in good condition. Prior to, during, and af ter analysis, the samples were kept under lock with access only to authorized personnel by Enthalpy Analytical, Inc.

Analysis The samples were analyzed for formaldehyde using the analytical procedures in EPA Method 323, Measurement of Formaldehyde Emissions from Natural Gas-Fired Stationary Sources—Acetyl Acetone Derivitization Method (40 CFR Part 63, Appendix A). The acetylacetone reagent was made following the procedures in Section 7.2.1 and used within two weeks of preparation. Samples and standards are analyzed following th e procedures in Section 11.1. As specified in the method, any sample dilutions were performed on an aliquot of the original sample prior to the addition of acetyl acetone reagent.

The Hewlett Packard Model 8452A, Diode Array Spectrophotometer ("Larry" S/N 2610A 00705) was operated at 412 nm.

Calibration The calibration curve is located in the Calibration Curve Spectra section of this report. QC Notes The following Quality Control Samp les (8.4) were analyzed: field duplicate (8.4.1), spiked sample ( 8.4.2), and field blank. Additionally, Analytical Quality Control (11.2) sa mples include laboratory duplicates (11.2.1) and analytical blanks (11.1.2).
All sample preparation and analytical holding times specified in the method were met. In Section 13.4, Sample Stability, the specified analytical holding time is 14 days.

Reporting Notes The results presented in this report are representative of the samples as provided to the laboratory.

# General Reporting Notes

The following are general reporting notes that are a pplicable to all Enthalpy Analytical, Inc. data reports, unless specifically noted otherwise.

 The acronym MDL represents the Minimum Detection Limit. Below this value the laboratory cannot determine the presence of the analyte of interest reliably.

 The acronym LOQ represents the Limit of Quantification. Below this value the laboratory cannot quantitate the analyte of interest within the criteria of the method.

 The acronym ND following a value indicates a non-detect or analytical result below the MDL.

 The letter J following a value indicates an analytical r esult between the MDL and the LOQ. A J flag indicates that the laboratory can positively identify th e analyte of interest as present, but the value should be considered an estimate.

 The letter E following a value indicates an analytical r esult exceeding 100% of the highest calibration point. The associated value should be considered as an estimate.

 The acronym DF represents Dilution Factor. This number represents dilution of the sample during the preparation and/or analysis process. The analyti cal result taken from a laboratory instrument is multiplied by the DF to determine the final undiluted sample results.

 The addition of MS to the Sample ID represents a Matrix Sp ike. An aliquot of an actual sample is spiked with a known amount of analyte so that a per cent recovery value can be determined. This shows what effect the sample matrix may have on the target analyte, i.e. whether or not anything in the sample matrix interferes with the analysis of the analyte(s).

 The addition of MSD to the Sample ID represents a Matrix Spike Duplicate. Prepared in the same manner as an MS, the use of duplicate matrix spikes allows further confirmation of laboratory quality by showing the consistency of results gained by performing the same steps multiple times.

 The addition of LD to the Sample ID represents a Laborat ory Duplicate. The analyst prepares an additional aliquot of sample for testing and the resu lts of the duplicate analysis are compared to the initial result. The result should have a difference value of within 10% of the initial result (if the results of the original analysis are greater than the LOQ).

 The addition of AD to the Sample ID represents an Alte rnate Dilution. The analyst prepares an additional aliquot at a different dilution factor (usu ally double the initial factor). This analysis helps confirm that no additional compound is present and coel uting or sharing absorbance with the analyte of interest, as they would have a different res ponse/absorbance than the analyte of interest.

 The Sample ID LCS represents a Laboratory Control Sample. Clean matrix, similar to the client sample matrix, prepared and analyzed by the laborator y using the same reagents, spiking standards and procedures used for the client samples. The LCS is used to assess the control of the laboratory’s analytical system. Whenever spikes are prepared for our client projects, two extra spikes are prepared. The extras (randomly chosen) are labeled with the asso ciated project number and kept in-house at the appropriate temperature conditions. When the project samples are received for analysis, the LCSs are analyzed to confirm that the analyte could be recovered from the media, separate from the samples which were used on the project and which may have been affected by source matrix, sample collection and/or sample transport.

# General Reporting Notes
(continued)

 Significant Figures : Where the reported value is much greater than unity (1.00) in the units expressed, the number is rounded to a whole number of units, rather than to 3 significant figures. For example, a value of 10,456.45 ug catch is rounded to 10,456 ug. Ther e are five significant digits displayed, but no confidence should be placed on more than two significant digits.

 Manual Integration : The data systems used for processing w ill flag manually integrated peaks with an “M”. There are several reasons a peak may be manually integrated. These reasons will be identified by the following two letter designations. The peak was not integrated by the software “NI” , the peak

was integrated incorrectly by the software “II” or the wrong peak was integrated by the software “WP” . These codes will accompany the analyst’s ma nual integration stamp placed next to the compound name.
