3.0 SOURCE OPERATION

3.1 PROCESS DESCRIPTION

The units tested were Caterpillar G3520C, Units 1-6. The engines are rated at 2,172 horsepower. The engine 

emissions are vented to the atmosphere through an exhaust system extending from the engine. The sample ports 

were located on a horizontal run connecting to the exhaust stack. All exhaust samples were continuously drawn 

from the exhaust stack at the sample ports. 

3.2 SAMPLING LOCATION 

The sample ports were located approximately nine feet above grade level on the exhaust system in a horizontal 

run connected to the exhaust stack. The horizontal runs measure approximately 18 inches in diameter. The ports 

are at least 2.0 duct diameters downstream from the last point of interference and 0.5 duct diameters upstream 

from the next point of interference. All exhaust samples for gaseous emissions were continuously drawn from the 

exhaust system at the sample ports from a single point near the center of each horizontal run. 

4.0 SAMPLING AND ANALYTICAL PROCEDURES

4.1 TEST METHODS 

The emission tests on the Caterpillar G3520C, Units 1-6 at the Covel Gardens Landfill Gas Power Station were 

performed following the United States Environmental Protection Agency (EPA) methods described by the Code 

of Federal Regulations (CFR). Table 4.1 outlines the specific methods performed on August 27, 2009. 

TABLE 4.1 

SUMMARY OF SAMPLING METHODS

Pollutant or Parameter Sampling 

Method Analysis Method 

Stack Flow Rate EPA Method 2 S-Type Pitot Tube 

O2, NOx, CO EPA CTM-034 Electrochemical Cell 

 

4.2 INSTRUMENT CONFIGURATION AND OPERATIONS FOR GAS ANALYSIS

The sampling and analysis procedures used during these tests conform with the methods outlined in the Code of 

Federal Regulations (CFR), Title 40, Part 60, Appendix A, Method 2; and 40 CFR 63, Appendix A, Conditional 

Test Method (CTM)-034. 

Figure 4.1 depicts the sample system used for the NOx, CO, and O2 tests. A stainless steel probe was inserted 

into the sample ports of the stack to extract gas measurements from the emission stream. The gas sample was 

continuously pulled through the probe and transported, via heat-traced Teflon® tubing, to a stainless steel 

minimum-contact condenser designed to dry the sample. Transportation of the sample, through Teflon® tubing, 

continued into the sample manifold within the portable analyzer via a stainless steel/Teflon® diaphragm pump. 

From the manifold, the sample was partitioned to the NOx, CO, and O2 cells. 
ed-09-sanantonio.tx-ecom#3-rpt 10 

 

Gaseous calibration standards were provided in aluminum cylinders with the concentrations certified by the 

vendor. EPA Protocol No. 1 was used to determine the cylinder concentrations where applicable (i.e. NOx 

calibration gases). 

Table 4.2 provides a description of the analyzer used for the instrument portion of the tests. All data from the 

continuous monitoring instrument was recorded using the Advanced DAS ECOM Software. Data records can be 

found in Appendix A and B of this report. 

Three test runs of approximately 10 minutes each were conducted on the Caterpillar G3520C, Units 1-6 

in the "as found" operating condition for NOx, CO, and O2. 

Exhaust flow rates were measured on Unit 2 at high load during the May 9, 2006 initial compliance 

demonstration. The Unit 2 exhaust flow rate determined in accordance with EPA Method 2 is representative of 

all units and is used to calculate emission rates. 

The stack gas analysis for O2, NOx, and CO concentration was performed in accordance with the procedures set 

forth in EPA CTM-034. The analyzer uses an electrochemical cell.

QUALITY ASSURANCE AND QUALITY CONTROL DATA 
ed-09-sanantonio.tx-ecom#3-rpt

 

QA/QC PROGRAM 

Air Hygiene ensures the quality and validity of its emission measurement and reporting procedures through a rigorous quality 

assurance (QA) program. The program is developed and administered by an internal QA team and encompasses five major areas: 

1. QA reviews of reports, laboratory work, and field testing 

2. Equipment calibration and maintenance 

3. Chain-of-custody 

4. Training 

5. Knowledge of current test methods 

Each of these areas is discussed individually below. 

QA Reviews 

Air Hygiene’s review procedure includes review of each source test report, along with laboratory and fieldwork, by the QA Team. 

The most important review is the one that takes place before a test program begins. The QA Team works closely with technical 

division personnel to prepare and review test protocols. Test protocol review includes selection of appropriate test procedures, 

evaluation of interferences or other restrictions that might preclude use of standard test procedures, and evaluation and/or development 

of alternate procedures. 

Equipment Calibration and Maintenance 

The equipment used to conduct the emission measurements is maintained according to the manufacturer’s instructions to ensure 

proper operation. In addition to the maintenance program, calibrations are carried out on each measurement device according to the 

schedule outlined by the Environmental Protection Agency. Quality control checks are also conducted in the field for each test

program. 

Chain-of-Custody 

Air Hygiene maintains full chain-of-custody documentation on all samples and data sheets. In addition to normal documentation of 

changes between field sample custodians, laboratory personnel, and field test personnel, Air Hygiene documents every individual who 

handles any test component in the field (e.g., probe wash, impinger loading and recovery, filter loading and recovery, etc.). Samples 

are stored in a locked area to which only Air Hygiene personnel have access. Field data sheets are secured at Air Hygiene’s offices 

upon return from the field. 

Training 

Personnel’s training is essential to ensure quality testing. Air Hygiene has formal and informal training programs, which include: 

1. Attendance at EPA-sponsored training courses 

2. Enrollment in EPA correspondence courses 

3 A requirement for all technicians to read and understand Air Hygiene’s QA manual 

4. In-house training and QA meetings on a regular basis 

5. Maintenance of training records 

Knowledge of Current Test Methods 

With the constant updating of standard test methods and the wide variety of emerging test procedures, it is essential that any qualified 

source tester keep abreast of new developments. Air Hygiene subscribes to services, which provide updates on EPA reference 

methods, rules, and regulations. Additionally, source test personnel regularly attend and present papers at testing and emission-related 

seminars and conferences. Air Hygiene personnel maintain membership in the Air and Waste Management Association and the 

American Industrial Hygiene Association.

COMBUSTION TESTING QUALITY ASSURANCE ACTIVITIES 

A number of quality assurance activities were undertaken before, during, and after this testing project. This section of the report 

combined with the documentation in Appendix C describe each of those activities. 

Each instrument’s response was checked and adjusted in the field prior to the collection of data via multi-point calibration. The 

instrument’s linearity was checked by adjusting its zero and span responses to zero nitrogen and an upscale calibration gas in the range 

of the expected concentrations. The instrument response was then challenged with other calibration gases of known concentration and 

accepted as being linear if the response of the other calibration gases agreed within plus or minus two percent of the range of predicted 

values. NO2 to NO conversion was checked via direct connect with an EPA Protocol certified concentration of NO2 in a balance of 

nitrogen. Conversion was verified to be between 90 and 110 percent. 

After each test run, the analyzers were checked for zero and span drift. This allowed each test run to be bracketed by calibrations and 

documents the precision of the data just collected. The criterion for acceptable data is that the instrument drift is no more than three 

percent of the full-scale response. The quality assurance worksheets in the following pages summarize all multipoint calibration 

checks and zero to span checks performed during the tests. These worksheets (as prepared from the data records of Appendix A) 

show that no drifts in excess of three percent occurred in the zero to span checks following each test run. 

The sampling systems were leak checked by demonstrating that a vacuum greater than 10 in Hg could be held for at least one minute 

with a decline of less than one in. Hg. A leak test was conducted after the sample system was set up and before the system was

dismantled. This test was conducted to ensure that ambient air had not diluted the sample. Any leakage detected prior to the tests 

would be repaired and another leak check conducted before testing commenced. No leaks were found during the pre or post-test leak 

checks. 

The absence of leaks in the sampling system was also verified by a sampling system bias check. The sampling system’s integrity was 

tested by comparing the responses of the analyzers to the calibration gases introduced via two paths. The first path was directly into 

the analyzer and the second path via the sample system at the sample probe. Any difference in the instrument responses by these two 

methods was attributed to sampling system bias or leakage. The criterion for acceptance is agreement within five percent of the span 

of the analyzer. 

The control gases used to calibrate the instruments were analyzed and certified by the compressed gas vendors to plus or minus one 

percent accuracy for all gases. EPA Protocol No. 1 was used, where applicable to assign the concentration values traceable to the 

National Institute of Standards and Technology (NIST), Standard Reference Materials (SRM’s). The gas calibration sheets as 

prepared by the vendor are contained in Appendix C. 

Air Hygiene collected and reported the enclosed test data in accordance with the procedures and quality assurance activities described 

in this test report. Air Hygiene makes no warranty as to the suitability of the test methods. Air Hygiene also assumes no liability 

relating to the interpretation and use of the test data.
