1.0 INTRODUCTION 

1.1 OVERVIEW 

TRC Environmental Corporation (TRC) of Lowell, Massachusetts was retained by Dominion to 

perform EPA Utility MACT ICR testing at the Chesterfield Power Station located at 500 

Coxendale Road in Chester, Virginia. 

Testing was conducted for Unit 6 at the Chester Power Station for Dioxin/Furan HAPs. 

Triplicate test runs were performed. Volumetric flow rate, the moisture content of the stack gas, 

and oxygen and carbon dioxide concentrations were also measured during each test run. All 

testing was conducted while the unit was operating at “normal” load under steady state 

conditions. 

Sampling and analysis procedures described in this document were conducted using procedures 

deemed acceptable by the United States Environmental Protection Agency (USEPA). TRC was 

responsible for the collection and analysis of all flue gas samples. 

Sampling and analysis was performed under the direction of Mr. Tom Lundin of TRC’s Lowell, 

Massachusetts office. Mr. Sean Warden and Mr. John Bowry of Dominion EMSG provided 

process and testing coordination at the facility. 

1.2 SCOPE OF WORK 

This section of the test protocol presents an overview of the scope of work and schedule 

associated with the testing of Unit 6 at the Chesterfield Power Station. The sample and 

analytical test matrix is presented in Table 1-1. The test program approach involved conducting 

a series of three test runs at the Unit 6 stack outlet for various pollutants, while the unit was 

operated at normal load under steady-state conditions. 

Testing was conducted for Dioxin/Furan HAPs. The results have been reported in lb/MMBtu, 
L2010-264 2

using Method 19 procedures, and ng/dscm corrected to 7% O2. 

1.3 TEST METHODS AND PARAMETERS 

The sampling methods utilized to complete the test program are presented below: 

40 CFR Part 60, Appendix A, EPA Methods 

 Method 1 and 2 Volumetric Flow Rate Determination

during the test program. Plant operating data collected by Dominion plant personnel have been 

included in the Final Report. The following data were recorded for the unit and averaged on an 

hourly and on a daily basis. 

 Coal Firing Rate (tons/hr) 

 Average Heat Input (MMBtu/hr) 

 Steam Output (k-lb steam-hr) 

 Facility CEMS data for O2 and CO2 (percent) 

 Stack Flow (DSCFM) 

 Flue Gas Temperature (degrees F) 

 Net Electrical Generation (MWh) 

 Gross Electrical Generation (MWe) 

 Pressure Drop Across FGD (inches H2O) 

 Sorbent Injection Rate (lb/hr) 
L2010-264 3

1.5 FUEL SAMPLING 

As-fired coal samples were collected by facility personnel during each dioxin/furan test run. At 

least three samples of the fuel combusted during each test run were collected, composited, and 

submitted for analyses. The samples were prepared for analyses in accordance with ASTM 

D2013-04. Analyses of the samples are detailed in Table 1-2.

2.0 SUMMARY OF RESULTS 

Testing for the U.S. EPA Utility MACT ICR was conducted at Chesterfield Unit 6 between April 

13, 2010 and April 15, 2010. As presented in Table 1-1, sampling for dioxin/furans was 

performed. 

2.1 TEST RESULTS FOR DIOXIN/FURANS 

Sampling for dioxin/furan organics emissions from Unit 6 was performed. The emission 

summary for dioxin/furan is presented in Table 2-1a. The emission summary for PCBs is 

presented in Table 2-1b. 

The Method 23 samples were received at the laboratory at a temperature of 11°C which is 5 

degrees above the upper limit of the recommended storage temperature of 4  2°C. TRC has 

concluded that this temperature excursion has had little or no adverse effect on the PCDD/PCDF 

and PCB sample results. This conclusion has been based on the fact that all of the PCDD/PCDF 

field spike recoveries for all of the effected samples were within the 70 to 130% recovery 

objectives. The field spikes are labeled dioxin and furan isomers that are spiked onto the XAD 

trap by the laboratory prior to shipping the traps to TRC for sampling. The acceptable field spike 

recoveries provide evidence that the samples have not exhibited any significant loss of the 

compounds of interest during shipping and handling as well as the exposure to the exhaust gas 

matrix during sampling.

3.0 FACILITY DESCRIPTION AND SAMPLING LOCATIONS 

3.1 FACILITY DESCRIPTION 

The Dominion Generation, Chesterfield Power Station consists of six units designated as Unit 3, 

Unit 4, Unit 5, Unit 6, Unit 7, and Unit 8. This test will focus on testing of Unit 6 only. The 

primary fuel for Unit 6 is coal. 

3.2 SAMPLING LOCATIONS 

The exhaust effluent from the Unit 6 Stack has an internal diameter of 29 ft. (348.0 inches). 

Four ports, located on the same plane, are present on the stack. Each sample port has a depth of 

5.0 inches. The sample ports are located 75.9 feet (equivalent to 3.74 stack diameters) upstream; 

and 234.5 feet (equivalent to 11.55 stack diameters) downstream from any disturbance. A 

diagram of the stack test location is presented in Figure 3-1. 

TRC conducted 24-point traverses for the dioxin/furan sampling. Table 3-1 presents the traverse 

points for the Unit 6 Exhaust Stack. Each port was sampled at 6 points to achieve the total of 24 

points.

program. 

 
L2010-264 13

4.3.1 Equipment Calibration 

Inspection and calibration of the equipment is a crucial step in ensuring the successful 

completion of the field effort. All equipment was inspected for proper operation and durability 

prior to calibration. Calibration of the following equipment was conducted in accordance with 

the procedures outlined in EPA documents entitled "Quality Assurance Handbook for Air 

Pollution Measurement Systems; Volume III - Stationary Source Specific Methods" and 40 CFR 

Part 60 Appendix A. Copies of the equipment calibration forms can be found in Appendix E. 

All calibrations were performed prior to the test program and included in the final report. 

 Probe Nozzles (QA Handbook, Vol III, Section 3.4.2, pp. 19) - averaged three 

internal diameter measurements of the nozzle; difference between high and low 

0.1 mm. Recalibrate, reshape and sharpen when nozzle becomes nicked, dented 

or corroded. 

 Pitot tubes (QA Handbook Vol III, Section 3.1.2, pp. 1-13) - measured for 

appropriate spacing and dimensions or calibrated in a wind tunnel. Rejection 

criteria is given on the calibration sheet. A post-test check inspected for damage. 

 Thermocouples (QA Handbook, Vol III, Section 3.4.2, pp. 12-18) – verified 

 against a mercury-in-glass thermometer at three points including the anticipated 

 measurement range. Acceptance limits - impinger + 2oF; DGM + 5.4oF; stack +

1.5 percent of stack temperature. 

 Dry gas meters (EPA 40 CFR Part 60, Method 5, Section 5.3) - calibrated against 

 a critical orifice. Acceptance criteria - pretest Yi = Y = + 0.02; post test Y = + 

 0.05 Yi. 

 Field barometer (QA Handbook, Vol III, Section 3.4.2, pp. 18-19) – compared 

 against a mercury-in-glass barometer or use Airport Station BP and correct for 

 elevation. Acceptance criteria -  0.02 in. Hg; post-test check will be the same. 

 Analytical balances (QA Handbook, Vol III, Section 3.4.2, pp. 19) – Acceptance 

 criteria - calibrate with Standard Class-S weights within  0.5 mg of stated value. 

 Corrective action: Have manufacturer recalibrate or adjust. 

4.3.2 Glassware Preparation 

The sample train glassware necessary for the EPA Method 23 sampling train was precleaned in 
L2010-264 14

accordance with the method. Special care was given to the removal of residual silicone grease 

sealants on ground glass connections of used glassware. 

4.3.3 Sample Media Preparation 

All reagents were checked in accordance with the TRC’s existing QC Program to minimize the 

probability of using contaminated solvents. This included the use of spectro-grade solvents from 

the same lot and the collection and analysis of the appropriate blanks. All filters were desiccated 

and weighed to the nearest 0.5 mg constant weight. 

XAD-2® resin used in the Method 23 sampling trains was packed by the Field Sampling 

Subcontractor laboratory(s) in specially designed sorbent traps. The XAD-2® resin was 

purchased pre-cleaned or prepared by the laboratory(s) to meet or exceed all quality control 

requirements specified in EPA Method 23, as applicable. 

4.4 ONSITE SAMPLING ACTIVITIES 

Onsite sampling activities included conducting velocity traverses, moisture measurements, and 

sampling for dioxin/furans. Oxygen and carbon dioxide measurements were also made. 

4.4.1 EPA Methods 1 and 2 for Velocity Measurements/Cyclonic Flow 

Velocity traverses were conducted on the outlet stack with an S-type pitot assembly in 

accordance with EPA Reference Methods 1 and 2. An S-type pitot tube with an attached 

inclined manometer was used to measure the exhaust velocities at the sampling location. An 

attached Type-K thermocouple with remote digital display was used to determine the flue gas 

temperature. During the test program, velocity measurements were conducted during each test 

run while operating the EPA Method 23, sampling trains. The required number of velocity 

measurements points for each sampling location was determined following EPA Method 1. 

Cyclonic flow checks were conducted in accordance with Section 2.4 of EPA Method 1. This 
L2010-264 15

procedure is referred to as the nulling technique. An S-type Pitot tube connected to an inclined 

manometer was used in this method. The Pitot tube was positioned at each traverse point so that 

the face openings of the Pitot tube were perpendicular to the stack cross-sectional plane. This 

position is called the “0 reference”. The velocity pressure (P) measurement is noted. If the P 

reading was zero, the cyclonic angle was recorded as 0. If the P reading was not zero, the 

Pitot tube was rotated clockwise or counter-clockwise until the P reading became zero. This 

angle was then measured with a leveled protractor and reported to the nearest degree. After this 

null technique was applied at each traverse point, the average of the cyclonic angles was 

calculated. If this average was less than 20, the flow condition was acceptable to test. 

4.4.2 EPA Method 3A/3B for O2/CO2 

Oxygen and carbon dioxide concentrations were determined at the sampling location for each 

test run in conjunction with a designated sampling train in accordance with either EPA Method 

3B “Gas Analysis for the Determination of Emission Rate Correction Factor or Excess Air.” 

An integrated sample was collected in a Tedlar bag during each test run. The sample gas was 

drawn through a stainless steel probe and through Teflon sampling line followed by a glass 

condenser unit to remove excess moisture which would interfere with the operation of the pump 

and flow meter. Approximately 20 liters of sample gas were collected during each test run. 

Following completion of the test run, the samples were given to Dominion plant personnel, for 

analyses. A sample from the Tedlar bag was drawn into O2 and CO2 analyzers and immediately 

analyzed for percent CO2 and percent O2. The analyzers had been calibrated in accordance with 

EPA Method 3A. 

The O2/CO2 concentrations were needed to calculate the flue gas molecular weight for 

determining volumetric flow rate as well as providing the oxygen concentration for correcting 

applicable emission rates to 7% O2. 
L2010-264 16

4.4.3 EPA Method 4 for Moisture Determination 

Moisture was determined for each test run according to EPA Reference Method 4, 

"Determination of Moisture Content in Stack Gases". The principle of this method is to remove 

the moisture from the sample stream and determine moisture either volumetrically or 

gravimetrically. Method 4 was used in conjunction with the acid gas sampling trains, semivolatile and formaldehyde tests, and the metals and particulate matter sampling trains. 

4.4.4 EPA Method 23 for Dioxin/Furan 

A sampling train was used to measure and determine the emission rate of select dioxins, furans, 

and PCBs during each test run in accordance with EPA Method 23, “Determination of 

Polychlorinated Dibenzo-p-Dioxins and Polychlorinated Dibenzofurans from Municipal Waste 

Combustors.” The sampling train consisted of a heated, glass-lined probe, with a glass buttonhook nozzle. A thermocouple and S-type Pitot tube attached to an inclined manometer were 

attached to the probe for measurement of gas temperature and velocity. The sample gas passed 

through the probe assembly to a heated glass fiber filter. The heated, glass-lined probe and filter 

holder were maintained at 248°F ±25°F throughout each test period. (Note: A heated transfer 

line of appropriate length was used between the sampling probe and the heated glass fiber filter 

holder. This heated transfer line was maintained within the same temperature range as the probe 

and filter holder.) Downstream of the heated filter, the gas passed through a water-cooled 

condenser module, then through a sorbent module containing 20 to 40 grams of XAD-2® resin. 

The XAD-2® module was kept at a temperature below 68°F. The gas then passed through a 

series of five ice-cooled impingers kept below 68°F to enable condensation of entrained 

moisture. The first impinger, acting as a condensate reservoir connected to the outlet of the 

XAD-2® module, was modified with a short stem so that the sample gas did not bubble through 

the collected condensate. The next two impingers each contained 100 milliliters of deionized 

water. The fourth impinger was empty and the fifth impinger contained a preweighed amount of 

silica gel. All connections within the train were glass or Teflon®. No sealant greases were used. 

The impingers were followed by a dry gas meter, pump, and calibrated orifice meter. 
L2010-264 17

One sample was collected for each test run. Each sample was collected over an eight-hour 

period. Sampling was isokinetic (±10 percent) with readings of exhaust gas parameters recorded 

at every sampling point during the traverse. These readings included the time, velocity, pressure, 

the target orifice pressure, the actual orifice pressure, stack gas temperature, probe temperature, 

filter temperature, heated transfer line temperature, sorbent trap temperature, silica gel impinger 

temperature, dry gas meter inlet and outlet temperatures, dry gas meter volume, and sample 

vacuum. 

Leak checks of the entire EPA Method 23 sampling train were performed before and after 

sampling in each port. In the event any portion of the train was disassembled and reassembled, 

leak checks were performed prior to disassembling, and following reassembly of the train. All 

leak checks and leakage rates were documented on the relevant field test data sheet. The 

acceptance criteria for the EPA Method 23 train was a leak rate of 0.02 cubic feet per minute at 

a vacuum equal to or greater than the maximum value reached during the sampling run. 

Following the completion of each test run, the sampling train was leak checked and then 

transported to a recovery area on-site. The sample recovery sequence was as follows: 

 Noted the condition of the train (i.e., filter condition, color of impinger contents, color of 

silica gel, etc.). 

 Filter - The filter was removed carefully from the filter holder and placed in its original 

glass petri dish. Cleaned tweezers were used to handle the filter. The filter was folded, if 

necessary, with the particulate cake inside the fold. Any particulate matter and filter 

fibers that adhered to the filter holder gasket were transferred to the container by using a 

dry inert bristle brush and a sharp-edged blade. The container was sealed with Teflon®

tape and labeled with the appropriate sample information. 

 Sorbent module - The XAD-2® resin sorbent module was removed from the train, tightly 

capped at both ends with Teflon® tape and aluminum foil, labeled and stored on-site on 

ice, or equivalent, for transport to the laboratory. Care was taken to ensure that no ice 

water leaked into the stored traps or any other train component. 

 Front-half rinse - Material deposited in the nozzle, probe liner, heated transfer line, and 

the front half of the filter holder was quantitatively recovered. To prevent contamination 

of the sample, all openings were sealed with Teflon tape just after sample train 

disassembly and until recovery was about to begin. In addition, nitrile gloves were worn 

during all recovery procedures and all recovery solvents were stored in appropriate 
L2010-264 18

containers. The train components were brushed while rinsing three times each with 

acetone. The outside of the probe, the Pitot tube, and the nozzle were cleaned to prevent 

particulates from being brushed into the sample bottle. The probe liner was tilted and 

rotated while squirting acetone into the upper end to assure complete wetting of the inside 

surface. Acetone was then squirted into the upper end while pushing the probe brush 

through the liner with a twisting motion, with the drainage caught in the sample bottle. 

The brushing procedure was repeated two more times or until no particles were visible in 

the drainage and a visual inspection of the liner revealed no particles remaining inside. 

The heated transfer line was rinsed and brushed through the entire length of the line with 

acetone. All rinsate was collected into the same container. The brush was rinsed into the 

sample bottle to collect any particulates that may have been retained within the bristles. 

 Back-half rinse - The back half of the filter holder, the connecting line between the filter 

holder and the condenser, and the condenser itself (if separate from the trap) were rinsed 

three times with acetone. These rinses were added to the same container as the front-half 

rinses. 

 Front-half and Back-half rinses with toluene – Repeated the acetone rinses described 

above using toluene as the rinse solvent. These rinses were collected in a separate 

container. After all the rinses had been collected, the lid on the sample containers was 

tightened securely. As a precaution in case of leakage, the liquid level was marked on the 

sample container and the cap sealed with Teflon® tape. 

 Impinger water (first four impingers) - Any color or film in the impinger water was noted 

on the sample recovery form. The entrained moisture in the first four impingers was 

measured to within ±1 milliliter by using a graduated cylinder or by weighing to within 

0.5 grams, and the data recorded appropriately. This information was used to calculate 

the moisture content of the effluent gas. The impinger liquid from the second, third and 

fourth impingers was discarded after the volume or weight is recorded. 

 The condensate from the first impinger was placed in a sample container. More than one 

container was used, if necessary. The condensate knockout was then rinsed three times 

each with acetone and methylene chloride into the same container used to collect the 

condensate. [Note: The condensate rinse should not be collected into the same container 

as the back-half rinses to preclude introduction of condensate fractions, which were to be 

analyzed for PCBs only, to the back-half fraction, which was to be analyzed for dioxins 

and furans in addition to PCBs. In addition, the use of toluene was not indicated for 

rinsing of the condensate impinger as methylene chloride is an effective solvent for 

capturing any PCBs present and to preclude the introduction of toluene into this sample 

fraction as it could unnecessarily complicate the extraction of this sample fraction.] 

 Silica gel (fifth impinger) - The color of the indicating silica gel was noted on the 

recovery form to determine if it had been completely spent. The impinger was weighed 

to within ±0.5 grams using a triple beam balance, or equivalent. The gain in weight was 

used for moisture calculations. Analysis was not required. 
L2010-264 19

 All containers were checked to ensure proper sealing, proper labeling and that all liquid 

levels were marked. All samples were then logged onto a chain-of-custody record. 

The EPA Method 23 train yielded the following samples: 

 Filter, 

 XAD-2® module, 

 Front-half and Back-half Acetone solvent rinse, and 

 Front-half and Back-half Toluene solvent rinse 

For the purpose of PCB analysis of this combined sampling train, the filter and front-half solvent 

rinse were combined to form a sample fraction for analysis (i.e., the front-half fraction). The 

XAD-2® module and back-half solvent rinse fractions were extracted to form a sample fraction 

for analysis (i.e., the back-half fraction). 
L2010-264 20

5.0 ANALYTICAL PROCEDURES AND CALCULATIONS 

This section delineates the analytical procedures and calculations, which were used to analyze 

and report the sample results for this test program. 

5.1 ANALYTICAL PROCEDURES 

Analyses of the Method 23 Dioxin/Furan sample trains were performed by TRC’s subcontract 

laboratory. Samples were extracted in accordance with Method 23. Samples were analyzed 

using a high resolution gas chromatography/high resolution mass spectrometry (HRGC/HRMS) 

with isotopic dilution, such as described in EPA Method 1668 or 1668A. 

5.2 CALCULATIONS

6.0 QUALITY ASSURANCE 

6.1 OVERVIEW 

TRC Environmental Corporation management is fully committed to an effective Quality 

Assurance/Quality Control Program whose objective is the delivery of a quality product. For 

much of TRC's work, that product is data resulting from field measurements, sampling and 

analysis activities, engineering assessments, and the analysis of gathered data for planning 

purposes. The Quality Assurance Program works to provide complete, precise, accurate, 

representative data in a timely manner for each project, considering both the project's needs and 

budget constraints. 

This section highlights the specific QA/QC procedures that were followed for this Test Program. 

6.2 FIELD QUALITY CONTROL SUMMARY 

6.2.1 Calibration Procedures 

Calibration of the field sampling equipment was performed prior to the field sampling effort. 

Copies of the calibration sheets were submitted to the field team leader to take onsite and placed 

into the project file. Calibrations were performed as described in the EPA publications "Quality 

Assurance Handbook for Air Pollution Measurement Systems; Volume III - Stationary Source 

Specific Methods" and EPA 40 CFR Part 60 Appendix A. Equipment to be calibrated included 

the sample metering system, nozzles, barometers, thermocouples, and Pitot tubes. All 

calibrations were available for review during the test program. Copies of the example equipment 

calibration forms are presented found in Appendix E. 
L2010-264 24

6.2.2 Equipment Leak Checks 

Prior to sampling, each sampling train was leak checked according to the procedures outlined in 

EPA Reference Method 23. Final leak checks were performed to ensure that no leaks develop in 

the train during the course of each test run. All leakage rates, if any found, were recorded on the 

appropriate field data sheet. 

6.2.3 Cyclonic Flow Check 

The absence of cyclonic flow at the stack was established prior to sampling, in accordance with 

Section 2.4 of EPA Method 1. 

6.2.4 Method Blanks 

One Method blank for the Methods 23 sampling train was collected during the field-sampling 

program to ensure sample quality. 

6.3 SAMPLE CHAIN OF CUSTODY 

Chain-of-custody of the samples were initiated and maintained as follows: 

• Each sample that was collected was labeled, sealed, and the liquid level marked on 

appropriate samples. 

• Each sample was recorded on the chain-of-custody form. 

• Custody of the samples were retained by TRC until delivery to the analytical laboratory 

for analysis. 

6.4 DATA REDUCTION, VALIDATION, AND REPORTING 

 

Specific QC measures were used to ensure the generation of reliable data from sampling and 

analysis activities. Proper collection and organization of accurate information followed by clear 

and concise reporting of the data is a primary goal in all projects. 
L2010-264 25

6.4.1 Field Data Reduction 

The Field Team Leader and at least one other field crewmember reviewed the data collected in 

the field. Any recording errors or discrepancies were noted on the field data sheet. The field 

sampling data sheets are presented in Appendix A. 

6.4.2 Laboratory Analysis Data Reduction 

Analytical results were reduced to concentration units specified by the analytical procedures, 

using the equations provided in the analytical procedures. 

6.4.3 Data Validation 

TRC supervisory and QC personnel use validation methods and criteria appropriate to the type of 

data and the purpose of the measurement. Records of all data were maintained, including any 

judged to be an "outlying" or spurious value. The persons who validated the data have sufficient 

knowledge of the technical work to identify questionable values. 

The Field Team Leader and/or the Field QC Coordinator based on their review of the adherence 

to an approved sampling protocol and written sample collection procedure validated fieldsampling data. 

Analytical data were validated using criteria outlined below. TRC utilized results from the field 

method blank to further validate analytical results. Furthermore, TRC reviewed all laboratory 

raw analytical data to verify the calculated results presented. 

The following criteria were used to evaluate the field sampling data: 

 • Use of approved test procedures; 

 • Proper operation of the process being tested; 

 • Use of properly operating and calibrated equipment; 

 • Leak checks conducted before and after tests; 

 • Use of reagents conforming to QC specified criteria;
