## 3.0 SOURCE OPERATION 3.1 PROCESS DESCRIPTION The units tested were Caterpillar G3520C N/A, 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 th e 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. Th e horizontal runs measure approximately 18 feet 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 singl e point near the center of each horizontal run.


## 4.0 SAMPLING AND AN ALYTICAL PROCEDURES 4.1 TEST METHODS The emission tests on the Caterpillar G3520C N/A, Units 1-6 at the Covel Gardens Landfill Gas Power Station were performed following United States Environmental Pr otection Agency (EPA) methods described by the Code of Federal Regulations (CFR). Table 4.1 outlines the specific methods performed on June 3, 2008. TABLE 4.1 SUMMARY OF SAMPLING METHODS

Pollutant or Parameter Sampling Method Analysis Method Stack Flow Rate EPA Method 2 S-Type Pitot Tube O 2 

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



## 4.2 INSTRUMENT CONFIGURATION AND OPERATIONS FOR GAS ANALYSIS The sampling and analysis procedures used during these t ests 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 O 2 

## tests. A stainless steel probe was inserted into the sample ports of the stack to extract gas measu rements from the emission stream. The gas sample was continuously pulled through the prob e 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 O 2 

## cells.

## ed-08-sanantonio-tx-ecom#3-rpt 10 Gaseous calibration standards were pr ovided in aluminum cylinders with the concentrations certified by the vendor. EPA Protocol No. 1 was used to determine th e 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 w as recorded using the Advanced DAS EC OM Software. Data records can be found in Appendix A and B of this report. Three test runs of approximately 10 minutes each we re conducted on the Caterpilla r G3520C N/A, Units 1-6 in the "as found" operating condition for NOx, CO, and O 2 

## . Exhaust flow rates were measured on Unit 2 at hi gh load during the May 9, 2006 initial compliance demonstration. The Unit 2 exhaust flow rate determin ed 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 

## , NOx, and CO concentration was performed in accordance with the procedures set forth in EPA CTM-034. The analyzer uses an electrochemical cell. TABLE 4.2 ANALYTICAL INSTRUMENTATION

## QA/QC PROGRAM Air Hygiene ensures the quality and validity of its emission meas urement and reporting procedures through a rigorous quality assurance (QA) program. The program is developed and administer ed by an internal QA team and encompasses five major areas: 1. QA reviews of reports, labo ratory 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 revi ew of each source test report, along with la boratory 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 procedure s, evaluation of interferences or other restrictions that might preclude use of standard test procedures, and evaluation and/or de velopment of alternate procedures. Equipment Calibration and Maintenance The equipment used to conduct the emission measurements is ma intained according to the manufactur er’s instructions to ensure proper operation. In addition to the maintenance program, calibrations ar e 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 recove ry, 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 re ad 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 developm ents. Air Hygiene subscribes to services, which provide updates on EPA reference methods, rules, and regulations. Additionally, source test personn el regularly attend and present papers at testing and emissi on-related seminars and conferences. Air Hygiene personnel maintain memb ership in the Air and Waste Management Association and the American Industrial Hygiene Association.

## COMBUSTION TESTING QUAL ITY ASSURANCE ACTIVITIES A number of quality assurance activities were undertaken before, dur ing, and after this testing project. This section of the r eport 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 an d an upscale calibration gas in the range of the expected concentrations. The instru ment response was then challenged with other calibration gases of known concentratio n and accepted as being linear if the response of the other calibration ga ses agreed within plus or mi nus two percent of the range of predicted values. NO 2 

### to NO conversion was checked via direct connect with an EPA Protocol certified concentration of NO 2 

### in a balance of nitrogen. Conversion was verified to be between 90 and 110 percent. After each test run, the analyzers were chec ked for zero and span drift. This allowe d each test run to be bracketed by calibra tions and documents the precision of the data just co llected. 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 calibrati on checks and zero to span checks pe rformed during the tests. These worksheets (as prepared from the data records of Appendix A) show that no drifts in excess of three percent occurre d in the zero to span check s 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 minu te with a decline of less than one in. Hg. A leak test was conduct ed 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 l eak checks. The absence of leaks in the sampling system was also verified by a sampling system bi as 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 direc tly into the analyzer and the second path via the sample system at the sample probe. An y difference in the instru ment responses by thes e two methods was attributed to sampli ng system bias or leakage. Th e criterion for acceptance is agreem ent within five percent of th e 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, wh ere applicable to assign the co ncentration 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 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.
