1.0 INTRODUCTION 

Air Hygiene International, Inc. (Air Hygiene) has completed the stack sampling survey for nitrogen 

oxides (NOx), carbon monoxide (CO), and oxygen (O2) from the exhausts of the Caterpillar G3520C, 

Units 1 - 6 at Energy Developments’ Covel Gardens Landfill Gas Power Station near San Antonio, 

Texas. This report details the background information, test results, process description, 

sampling/analysis methodology, and quality control/assurance activities of the stack sampling survey 

conducted on January 4, 2007. 

1.1 TEST PURPOSE AND OBJECTIVES

The purpose of the test was to conduct the quarterly emission test to document emission levels of 

selected pollutants at normal operation levels of the designated engines. The information will be used 

to confirm compliance with the air quality permit requirements. The specific objective was to 

determine the emission concentration of NOx, CO, and O2 from the exhausts of Energy Developments’ 

Caterpillar G3520C, Units 1 - 6 during normal operating conditions.

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 engines emissions are vented to the atmosphere through an exhaust system extending from the 

engine. The sample ports were located on the exhaust stacks. All exhaust samples were continuously 

drawn from the exhaust stacks at the sample ports. 

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 was performed following EPA methods described by the Code of Federal Regulations (CFR), 

Title 40, Part 60, Appendix A and Title 40, Part 63, Appendix A, Conditional Test Method (CTM)-

034. Table 4.1 below outlines the specific methods performed on January 4, 2007.

4.2 INSTRUMENT CONFIGURATION AND OPERATIONS FOR GAS ANALYSIS

The sampling and analysis procedures used during these tests conform in principle with the methods 

outlined in the Code of Federal Regulations (CFR), Title 40, Part 60, Appendix A, Methods 2, and 

CFR, Title 40, Part 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 port 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 the ECOM-AC portable gas analyzer. 

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). 
ed-07-sanantonio-tx-ecom#1.doc Page 10 

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 of this report. 

Three test runs of approximately 10 minutes each were conducted on the engines in the “as found” 

operating condition of the Caterpillar G3520C, Units 1 - 6 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 concentrations was performed in accordance with the 

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

Quality Assurance Activities 
App. B 

QUALITY ASSURANCE PROGRAM SUMMARY 

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.
