### This section contains a briefdescription ofthe brick kiln, the control devices and an air flow schematic. 

### 2.1 Discussion Triangle Brick operates three natural gas fired kilns (Kiln Nos. I, 2, and 3) at its facility in Merry Oaks, North Carolina. Kiln Nos. I and 2 vented emissions through a common scrubber CD-KIK2 control device. A twenty-four car shuttle was conveyed through Kilns I and 2 yielding approximately 24.69 tons/hr of bricks fired for the August I0, 2006 test. This production weight information was provided by Kathy Wheeler ofTriangle Brick. The flue gases were withdrawn from the gas-fired tunnel(s) through a scrubber, !.D. fan, and stack to the atmosphere. Figure I details the air flow schematic. Production datawas recorded by Triangle Brickpersonnel and is presented in Appendix D.

### 3.0 SAMPLING METHODS September I, 2006 Trigon Project No. 046-06-076

This section describes the sampling strategy, sampling and analytical methods, and qualityassurance/quality control procedures implemented during this project. 

### 3.1 Sampling Strategy The sampling and analytical procedures used during this test program were those established by the US EPA. The sampling runs were conducted in triplicate to validate the sampling. Tests were conducted during normal operatingconditions. 

### 3.2 Sampling and Analytical Procedures The US EPA methods used in this sampling program were Method I for the location ofsampling ports and points, and determination ofcyclonic flow, Method 2 for volumetric flow rate determination, Method 3 for the determination ofdry molecular weight ofthe stack gas, Method 4 for the determination ofmoisture in the stack gas. Methods 5 and 26A were used for the determination ofparticulate, hydrogen chloride and hydrogen fluoride emissions. A sampling and analysis synopsis for these methods is discussed brieflyin the following subsections. These test methods are available in the Code ofFederal Regulations Volume 40, Part 60 orbyrequest from Trigon. 

### 3.3 Sampling Ports, Traverse Points and Cyclonic Flow Determination The sampling location wasprepared according to the criteriain Method 1. Theduct diameters upstream and downstream from the samplingports were determined priorto sampling. Thenumber oftraverse points was chosen withrespect to samplingport location. Forparticulate traverses Method 1 specifies a minimum of8 traverse points for sampling ports located >8/>2 downstream/upstream stack diameters from flow disturbances and 24 traverse points when located >2/>0.5. The amount ofcyclonic flow was determined according to the criteria detailed in Method I. 

### 3.4 Stack Gas Velocity and Volumetric Flow Rate Determination Method 2 is used for determining the average gas velocity in a stack from measurements ofgas density and the average velocityhead with a TypeS (Stausscheibe orreverse type) pitot tube. Thismethod is applicable for quantifYing gas flows whichmeet the criteria ofMethod I. In principle, measurements ofvelocity head and temperature are performed at the traverse points specified by Method I. A properly scaled differential

### pressure gauge was selected for the range ofi.\p values encountered during the traverse. A 0 to I 0 inches of water inclined manometer was used as the differential pressure gauge. During this project, the sampling locations met the criteria detailed in Method I. Gas stream density was determined by Method 3. Moisture determination was performed by Method 4. The principal components ofthe gas velocity measurement systemwere sequentially: • A calibrated stainless steel TypeSpilot tube and Type K thermocouple; • Leak-free interface tubing between pitot tube and differential pressure gauge; • A 0 to I 0 inch inclined manometer; and • An

### NIST traceable pyrometer. The apparatus was set-up according to manufacturer and reference method recommendations. Pre-test and post-test leak checks were conducted using procedures outlined in Method 2, Section 3.1. Velocityhead and temperature measurements were performed at the traverse points specified by Method 1. The atmospheric and static pressure ofthe stack was also determined for the velocity head readings. The volumetric flow rate calculations used were those specified in Method 2, Section 5. A more comprehensive explanation of the reference method is detailed in the Quality Assurance Handbook for Air Pollution Measurement Systems: Volume Ill, EPA/600/R-94/038c, (QA Handbook) FieldProcedure 2. 

### 3.5 Dry Molecular Weight Determination Method 3 is applicable for determining carbon dioxide and oxygen concentrations and dry molecularweight ofa sample from a gas stream ofa fossil-fuel combustion process. This method may also be applicable to other processes where it has been determined that compounds other than carbon dioxide, oxygen, carbon monoxide, and nitrogen are not present in concentrations sufficient to affect the results. In

### principle, a gas sample was withdrawn from the emission source by multi-point, integrated sampling. The collected sample was then analyzed for percent carbon dioxide, percent oxygen, and percent carbon monoxide. The drymolecular weight determination was performed by an Orsat analyzer. During this project, the gaseous components were collected using a Method 3 sampling system following the analytical procedures outlined in the reference method. The principal components of the sampling system were sequentially:

### • A stainless steel probe; 

### • A one-way squeezebulb, to transport the sample to the Tedlarbag; 

### • A saturatortube to remove particulatematter and excess moisture; and September I, 2006 Trigon Projecl No. 046-06-076



### • Aleak-free Tedlarbag equipped with a double-end shut-offquick connect. The analysis was performed with an Orsat type combustion gas analyzer within 

### 8 hours of sample collection. The dry molecular weight was calculated using Equation 3-1, 

### Section 7 

### ofMethod 3. 

### The analyzer was maintained and operated according to the instructions recommended by the manufacturer and in accordance with Method 3 criteria. The analyzer was leak-checked according to Section 6 ofMethod 3. The oxygen reagent was validated by analyzing a sample ofambient air which must meet the specifications of20.9%

## ±0.3%. 

### 3.6 MoistureDetermination Method 4 involves the determination of stack gas moisture. The moisture content is used to correct the emission concentration or mass emission rate to a dry basis. EPA Method 4 and 

### FieldProcedure 4 ofthe QA Handbook was used to measure stack gas moisture content. 

### Field Procedure 4 provides detailed information on the application ofMethod4. Preliminary flue gas moisture content (for purposes ofsetting the isokinetic flow rate) was determined using wet bulb/dry bulb thermometers and partial pressure, vapor and saturated vapor pressure equations. This technique is described in Method 4 and is summarizedbelow: • Moisten the wet bulbthermometer wickwithdeionizedwater; • Insert both thermometers into the flue gas stream and monitor the wet bulb temperature; • When the wet bulb temperature has stabilized, record both the wet bulb and dry bulb thermometer temperatures; and • Calculate the flue gas moisture content (PMV) using the appropriate equations. The moisture content for emission rate calculations was determined in conjunction with the Method 5/26A isokinetic sampling train. The reference method involves the withdrawal of gaseous and particulate pollutants from the emission source at an isokinetic rate using a Method 5 sampling system. The sampling and analytical procedure for reference Method 4 will be discussed in detail in the following sections with the isok:inetic sampling procedures.

### 3.7 ParticulateMatter, Hydrogen Chloride, andHydrogen FluorideSampling Testing for particulate matter, hydrogen chloride, and hydrogen fluoride was performed according to Method 26A procedures. Gaseous and particulate pollutants were withdrawn isokinetically from the emission source and collected in a multi-component sampling train. Inprinciple, particulate matterthat was condensed at orabove the filtration temperature ofapproximately 248 degrees Fahrenheit was collected on a tared quartz fiber filter. The gaseous components were then bubbled through a measured volume ofO.IN sulfuric acid and 0.1N sodium hydroxide to determine the moisture, hydrogen chloride, and hydrogen fluoride content of the emission source. The principal components of the sampling system were sequentially: • A borosilicate glass sample nozzle and probe liner; • A heated (248°F ±25°F)probe and filter assembly withtared quartz fiber filter; • An impinger train consisting offive sequential impingers. Impingers one and two containing 100 

### m1 each of an absorbing solution consisting of dilute sulfuric acid (0.1N H2S04). Impingers three and four contained 100 

### m1 ofdilute sodium hydroxide (O.lN NaOH) followed by a final impinger containing 200 grams ofsilica gel; and • A metering system capable of maintaining an isokinetic sampling rate and accurately determiningthe sample volume according to specifications in APTD-0581. Sample clean up began immediately after each test run. The filter, which collected the sample, was carefully removed from the Teflon filter support and sealed in a Petri dish. The nozzle, probe liner, and front filter-half ofthe filter assembly were rinsed with acetone into a glass storage container, which was sealed, and the liquid level marked. The sample containers were transported to Trigon's Air Quality Laboratory in Charlotte, North Carolina for particulatematter analysis. Hydrogen chloride and hydrogen fluoride were collected in the O.lN sulfuric acid solution in impingers one and two. The liquid in the first two impingers was measured to the nearest milliliter and recorded in order to determine the moisture content. 1be collected sample was placed in a high-density polyethylene (HOPE) storage container along with the deionized water rinse of impingers one, two, three and connecting glassware. The containerwas sealed and the liquid level was marked.
The moisture collected by the silica gel in the sixth impinger was determined to the nearest 0.1 gram. Collected condensate measurements were recorded on the "moisture determination and sample recovery

### data analysis" form. The samples were then shipped to Element One Laboratories ofWilmington, North Carolina with chain-of-custody documentation where they were analyzed by ion chromatography. Results ofthe hydrogen chloride and hydrogen fluoride analysis along with Element One's quality assurance data package can be found inAppendix C. The particulate matter analyses began by transferring the acetone samples to tared beakers. These samples were taken to dryness, and then placed in a desiccator along with the filters for an initial drying period of24 hours. The particulate mass was determined gravimetrically. The tare weights ofthe filters and beakers were subtracted from the final weights to determine the gross particulateweight.
An 

### aliquot ofthe reagent grade acetone was analyzed to determine the blankcorrection factor. The acetone rinse (corrected for the blank) was added to the filter catch to obtain the total particulate weight. The particulate samples and method blanks were analyzed by Trigon Engineering Consultants, Inc. personnel. The laboratory analyses and chainofcustody documentation can be found inAppendix C. 

### 3.9 SamplingPorts and Points The dimensions of the stacks and the location of the sampling ports and points are detailed in Figure 2. Method I sampling criteria was maintained. The stack cross section for Kiln Nos. I and 2 was divided into 12 equal areas. The ports for each stack were labeled A and B. During the test runs onKiln Nos. I and 2, the traverse points were sampled for 7.5 minutes per pointwhich yielded a total test time of90minutes.

3.6 QualityAssurance and Quality Control September l, 2006 Tngon Project No. 046-06-076
Trigon has established quality assurance and quality control 

### (QNQC) guidelines for providing quality sampling and analytical data from source tests. These 

### QNQCprocedures were implemented to ensure the acceptability andreliabilityofthe data generated. In summary, an appropriate degree ofdata quality was maintained throughout this project. Leakchecks and isokinetic QA criteria were met. The sampling trains were leak checked prior to and immediately after sampling. Leakrates for the isokinetic sampling trains were less than the maximum criterion of0.02 cubic feet perminute. The sampling rates were also within the 100% ± 10% criterion. Qualitycontrol procedures for the particulatematter determinations have included the analysis ofan acetone rinse blank, which mustbe less than 0.00I% for the acetone residue. Spike and recoveries were performed for the sampling methodologies used. An analyte spike was added to a portion ofa prepared sample andrecovered to within 70 and 130 percent of the known concentration. The results of the QA criteria for this project are summarized in the following tables and can be. Detailed results of the method blanks are reported in Appendix C withthe laboratory data.
