### 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 February 16, 2008. 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 extractgas 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-08-sanantonio-tx-ecom#1-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.

### App. B COMBUSTION TESTING QUAL ITY ASSURANCE ACTIVITIES A number of quality assurance activities were undertaken before, during, and after this testing project. This section of the r eport combined with the documentation in Appendix B and 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 ambient air and an upscale calibration gas in th e range of the expected concentrations. The instrument response was then challenged with other calib ration gases of known concentratio n and accepted as being linear if the response of the other calibration ga ses agreed within plus or minus two percent of the range of predicted values. At the end of the test day, the analyzers were checked for zero a nd span drift. This allowed each test run to be bracketed by calibrations and documents the precision of the data just collect ed. The criterion for acceptable data is that the instrument drift is no more than three of the full-scale response. These worksheets (as prepared from the data records of Appendix B) show that no dr ifts in excess of three percent occurred in the zero to span checks following each test run / period. The sampling systems were leak checked by demonstrating the zero fl ow was detected in the instrument rotameter. A leak test wa s conducted after the sample system was set up and before the system was dismantled. This test wa s conducted to ensure that ambi ent air had not diluted the sample. Any leakage detected prior to the tests would be repaired and another leak check conducted bef ore testing commenced. No leaks were found during the pre or post-test leak checks. The control gases used to calibrate the in struments were analyzed and certified by th e compressed gas vendors to plus or minus one percent accuracy for all gases. EPA Protocol No. 1 was used, wh ere applicable to assign the concentration values traceable to the National Institute of Standards and Technol ogy (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 de scribed in this test report. Air Hygiene makes no warranty as to the suitability of the test methods. Air Hygiene also assumes no lia bility relating to the interpretation and use of the test data.
