1.1 Summary of Test Program

Exhaust emission testing was performed on one (1) reciprocating internal combustion engine in Tulsa County, OK. Nordon Corporation of Round Rock, Texas, performed the exhaust emission testing on March 5, 2010.

This emission testing was performed to determine the formaldehyde (CH 2 

# O) concentrations from the exhaust of the engine for in

- house data. The testing was performed while the engine was operated at two engine load conditions (94% and 1% O 2 

# and 81% and 2% O 2 

# ) . The concen trations of oxygen (O 2 

# ) were measured to correct the concentration of formaldehyde to 15% O 2 

# . The test methods used followed the principles and procedures set forth in the Code of Federal Regulations , Title 40, Part 60, Appendix A, Method 3A and Code of Fe deral Regulations , Title 40, Part 63, Appendix A, CTM

3.1 Objectives and Test Matrix

The purpose of the test was to measure CH 2 

# O and O 2 

# concentrations from the exhaust of one 380 cubic inch (6.2 Liter) four

- stroke rich b urn engine without post

- combustion controls

Specific objectives:

• Measure the concentrations of CH 2 

# O and O 2 

# from one (1) reciprocating internal combustion engine.

• Two impinger trains (Train A and B) were used to collect samples to be used to measure CH 2 

# O concentrations from the exhaust of the engine. The two samples were collected during each run for duplication purposes.

• Perform emission sampling at 2 different engine load conditions (94% and 1% O 2 

# and 81% and 2% O 2 

# )

3.3 Field Test Changes and Problems

A deviation of CTM

- 323 was performed during formaldehyde sampling by using a critical orifice rather than a dry gas meter to determine sample volume. Nordon followed 4 0CFR60 Method 6 procedures for the orifice sampling. This approach was taken due to the greater sampling accuracy provided by the orifice at the required sample rate of 0.2 to 0.4 liters per minute.

No problems were experienced.

4.1 Test Methods

EPA Method 3A

- Determination of Oxygen Concentrations (Instrumental Analyzer Procedure) . An analyzer equipped with a paramagnetic cell was used to perform this method.

EPA Conditional Test Method 323 from 40CFR63

- Measurement of Formaldehyde Emissions from Natural Gas

- Fired Stationary Sources

— Acetyl Acetone Derivitization Method. The CH 2 

# O concentration is determined by the reaction of the sample to acetyl acetone. A colored derivative is created which is measured colorimetrically. A Thermo Scientific Spectrometer was used to determine the percent transmittance.

4.2 Instrumental Sample System

The instrumental sample system is used to collect samples for the determination of O 2 

# concentrations. A stainless st eel sample probe is used to extract exhaust gas samples continuously throughout each test run. Sample gas enters a sample probe and continues into a stainless steel electronically actuated solenoid 3

- way valve. The 3

- way valve is used to perform leak che cks and sample system bias checks. From the valve, the gas flows through a 3/8" Teflon® heat traced sample line to a stainless steel minimum contact condenser to dry the sample. From the condenser, a 3/8" Teflon sample line brings the exhaust gas to a ma nifold in the mobile analysis unit via a Teflon

- lined diaphragm pump. A manifold partitions the gas through quick

- connects so that each instrument can directly sample exhaust gas. Each instrument is equipped with a rotameter to maintain correct sample pr essure and flow rate. Each instrument is connected to an analog to digital USB converter and connected to a computer to document its response during calibration, quality assurance and control, and testing. Figure 4

- 1 provides an instrumental sample syste m diagram.

4.3 Impinger Sample System

The impinger sample system is used to collect sample for the determination CH 2 

# O concentrations. A sample pump attached to a calibrated orifice is used to draw a sample through an impinger train containing reagent grade deionized water. The impingers are submerged sufficiently in an ice bath to absorb formaldehyde in the reagent water. Figure 4

- 2 provides a schematic of the sample trains A and B.

5.1 QA Continuous Analyzers (Methods 3A)

Calibration Error Check

- Prior to and following each run, each continuous emission monitor's linearity response was checked using calibration gases. The instruments were calibrated at zero (nitrogen), and then calibrated at the high end of the scale. Next, an intermediate calibration standard was introduced to each analyzer to check t he instrument's response. The instruments were considered linear when their responses to the calibration gases were ±2% of the calibration standards as per the EPA Reference Methods.

Sample System Leak Check

- Prior to sampling, a leak check was perform ed on the entire sample system. The sampling system demonstrated the ability to hold at least a 10"Hg vacuum before and after the testing. The sample system held the vacuum for one minute with no vacuum loss for the pre

- test.

Sample System Bias Test

- A sample system bias test was also performed by introducing the zero gas and the calibration gas that closely approximates the stack effluent for each analyte. The sample system meets the bias specification if the difference between the calibration error check and the sample system bias check does not exceed ±5%.

Zero and Calibration Drift Assessment

- A zero and span calibration drift assessment was performed after each test run. The analyzer will be considered valid if the analyzer’s response does not drift more than ±2% of the span for either the zero and calibration gas over the duration of each run.

Calibration Gas Certifications

- The calibration gases used for the O 2 

# checks have been analyzed and certified by the vendor as being ±2% accurate. The O 2 

# Run QA in Appendix D document the calibration checks performed.

5.2 QA Formaldehyde Sampling and Analysis (CTM

- 323)

Sampling QA

- Reagent grade deionized water was used to absorb CH 2 

# O during the sampling. Leak checks were performed on each formaldehyde sampling train prior to and after sampling. A field blank sample was collected during the sampling and analyzed in the same manner as the field samples. A calibrated orifice was used to determine the amount of sample gas volume during each run. A post

- te st orifice check was performed upon completion of the project.

Laboratory Analysis QA

- Reagents were prepared the week of the test. A calibration curve was performed, and a correlation coefficient greater than 0.99 was observed. During CH 2 

# O analysis, sa mples spikes, lab blanks, and lab duplicates were performed and analyzed in the same manner as the field samples.
