### Stack Emissions Study from the Caterpillar G3520C, Units 1 - 6 prepared for Energy Developments

San Antonio, Texas May 23, 2007 1.0 INTRODUCTION Air Hygiene International, Inc. (Air Hygiene) has completed the stack sampling survey for nitrogen oxides (NOx), carbon monoxide (CO), and oxygen (O 2 

### ) from the exhausts of the Caterpillar G3520C, Units 1 - 6 at Energy Developments’ Covel Gardens Landfill Gas Powe r Station near San Antonio, Texas. This report details the background information, test results, pr ocess description, sampling/ analysis methodology, and quality control/assurance activities of the stack sampling survey conducted on May 23, 2007. 

### 1.1 TEST PURPOSE AND OBJECTIVES The purpose of the test was to conduct the quarterly emission tests 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 O 2 

### from the exhausts of Energy De velopments’ Caterpillar G3520C, Units 1 - 6 during normal operating conditions. 

### 1.2 SUMMARY OF TEST PROGRAM The following list details pertinent inform ation related to this specific project: 1.2.1 Participating Organizations: 3⁄4 Energy Developments 3⁄4 Air Hygiene 1.2.2 Industry: 3⁄4 Electric Utility 1.2.3 Plant Location: 3⁄4 Covel Gardens Landfill Gas Power Station near San Antonio, Texas 1.2.4 Equipment Tested: 3⁄4 Caterpillar G3520C, Units 1 - 6, Emission Point Numbers E1 - E6 1.2.5 Emission Points: 3⁄4 Exhausts of the Caterpillar G3520C, Units 1 - 6 1.2.6 Pollutants Measured: 3⁄4 NOx 3⁄4 CO 3⁄4 O 2

### 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 th rough an exhaust system extending from the engine. The sample ports were located on the exhaust stack. All exhaust samples were continuously drawn from the exhaust stack 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 th e 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 May 23, 2007. TABLE 4.1 SUMMARY OF SAMPLING METHODS

### , NOx, CO EPA CTM-034 Electrochemical Cell



### 4.2 INSTRUMENT CONFIGURATION AND OPERATIONS FOR GAS ANALYSIS The sampling and analysis procedures used during th ese 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, C onditional Test Method (CTM)-034. Figure 4.1 depicts the sample system used for the NOx, CO, and O 2 

### 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 tr ansported via heat-traced Teflon® tubing to the ECOM-AC portable gas analyzer. Gaseous calibration standards were pr ovided in aluminum cylinders with the concentrations certified by the vendor. EPA Protocol No. 1 was used to determin e the cylinder concentrations where applicable (i.e. NOx calibration gases).

### ed-07-sanantonio-tx-ecom#2-Rpt Page 10 Table 4.2 provides a description of the analyzer used fo r 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 G 3520C, Units 1 - 6 for NOx, CO, and O 2 

### . 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 O 2

# APPENDIX B 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 de veloped 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 te st 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 include s selection of appropriate test procedure s, evaluation of interferences or other restri ctions 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 m easurements is maintained according to the manufacturer’s instructions to ensure proper operation. In addition to the maintenance program, ca librations are carried out on each measurement device according to the schedule outlined by the Environmental Protection Agency. Qua lity 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 sheet s. In addition to normal documentation of changes between field sample custodians, laboratory personnel, and field test personne l, Air Hygiene documents every individual who handles any test component in the field (e.g., probe wash, impi nger 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 of fices upon return from the field. 

### Training Personnel’s training is essential to ensure quality testing. Air Hygiene has formal and informal training programs, which incl ude: 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 devel opments. Air Hygiene subscribes to serv ices, which provide updates on EPA reference methods, rules, and regulations. Additionally, source test pers onnel regularly attend and present papers at testing and emissi onrelated seminars and conferences. Air Hygi ene personnel maintain membership in the Air and Waste Manageme nt Association and the American Industrial Hygiene Association.Facility
