2. SOURCE DESCRIPTION AND PROCESS OPERATING DATA

This section provides descriptions of the process and 

emissions control equipment, as well as process 

operating conditions during the compliance testing.

2.1 PROCESS DESCRIPTION

The ALCOA Massena Operations East Plant primary 

aluminum reduction operation is located on the St. 

Lawrence Plant just east of Massena, NY. This 

operation is comprised of three horizontal stud 

soderberg (HSS) potlines. The potline operation 

manufactures metallic aluminum by the electrolytic 

reduction of alumina (Al2O3) in HSS reduction cells 

(or pots). Direct electrical current passing through a 

molten cryolite bath (the electrolyte) between a large 

carbon anode and the cathode electrolytically reduces 

the alumina added to the bath to aluminum and 

oxygen. The oxygen produced oxidizes and consumes 

the carbon anode. Molten aluminum is deposited and 

accumulates over time on the cathode beneath the 

layer bath. Periodically the molten aluminum is 

siphoned from beneath the bath and cast into foundry 

pig. 

Massena Operations East Plant is comprised of 504 

HSS pots with 168 pots in each of the three potlines. 

Each potline has two rooms with 84 pots each. 

Emissions from the potlines are captured by the 

hooding around each pot which are controlled 

through the primary emissions control system. The 

potline primary emissions control system is 

comprised of three dry scrubber devices and two wet 

scrubbers. The emissions not captured by the hooding 

are emitted through the roof vents in each room.

2.2 PROCESS OPERATING CONDITIONS DURING 

TESTING

Testing of each potline was conducted during a single 

operating condition that represented typical process 

operating conditions. During each test run facility 

personnel monitored and recorded the following 

process data:

» aluminum production (lb)

» potroom flow rates (dscf/min)

A summary of the aluminum production and potroom 

flow rate information are included in Appendix A.

3. TEST PROGRAM SUMMARY AND SAMPLE PROCEDURES

This section provides a summary of the test program 

conducted and a description of the test methods that 

were utilized as part of the field testing program. 

Source emission testing was conducted on the 

exhaust of the Method 14 Downcomer and the North 

and South FTC Scrubbers. A summary of the test 

parameters for each location can be found in Table 3.1 

below. Source testing was conducted in triplicate 

during normal process operating conditions as 

maintained by facility operators. Test run durations 

were approximately 240 minutes. 

3.1 SAMPLING SITE DESCRIPTION AND SAMPLING 

LOCATIONS

Test ports in the 14-inch inside diameter (ID) Line 1 

and 3 Potline Downcomer exhausts are located 

approximately 57 inches (4.1 diameters) downstream

of a bend in the ductwork and approximately 57 

inches (4.1 diameters) upstream of another bend. In 

accordance with USEPA Reference Method (RM) 1, a 

12-point traverse was conducted during each test run. 

A schematic of the test location can be found in 

Appendix B.

Test ports in the identical 240-inch ID FTC scrubber 

exhausts are located approximately 590 inches (2.0 

diameters) downstream of a bend in the ductwork 

and approximately 148 inches (0.5 diameters) 

upstream of the stack exhaust In accordance with 

USEPA RM 1, a 24-point traverse was conducted 

during each test run. A schematic of this test location 

can be found in Appendix B.

3.2 GAS VELOCITY AND VOLUMETRIC FLOW RATE

Exhaust gas velocities were calculated from 

differential pressure, measured using a stainless steel 

Type-S pitot tube and an inclined oil manometer, and 

exhaust gas temperatures, measured using a Type-K 

thermocouple attached to the pitot tube. USEPA RM 1 

was followed to establish equal areas across the 

cross-sectional diameter of the stacks at which 

differential pressure and temperature were 

measured.

the South FTC Scrubber 

3.3 GAS ANALYSIS AND DRY MOLECULAR WEIGHT

The molecular weight of the stack gas was measured 

using a Fyrite® apparatus in accordance with USEPA 

RM 3. These data, along with the moisture content 

and velocity data, were used to relate pollutant

concentrations to mass emission rates (lb/hr).

3.4 MOISTURE CONTENT

Moisture content during each test run was quantified 

utilizing procedures identified in USEPA RM 4 in 

conjunction with each isokinetic test run. A sample of 

gas was continuously collected using a dry gas meter 

stack sampling system and condensed in a series of 

impingers. The moisture content of the gas was 

measured as a change in the volume of the water 

collected in each impinger and the increased weight 

of the dessicant during each test run.

3.5 METAL AND PM EMISSIONS

Metal/PM emissions were conducted in accordance 

with USEPA RM 29 procedures. Metals measured 

included antimony, arsenic, beryllium, cadmium, 

chromium, cobalt, lead, manganese, nickel, selenium, 

and mercury. A detailed description of this train is 

provided in Method 29 of 40CFR Part 60. The sample 

train consisted of a glass nozzle, a heated glass-lined 

probe, five chilled impingers, and a metering console. 

Sample gas was drawn through the nozzle and probe 

isokinetically and then passed through a heated, glass 

fiber filter (248 oF ± 25 oF). Note that the probe and 

filter temperature were maintained at stack 

conditions for the downcomer testing. Upon exiting 

the filter, the gas was drawn through a series of six 

impingers containing the reagents prescribed by the 

method. The first and second impingers each 

contained 100 mls of 5% HNO3/10% H2O2 solution to 

enhance the collection of metals of interest. The third 

impinger was empty to catch any overflow from the 

first two impingers. The fourth and fifth impingers 

each contained 100 mls of a 10% H2O4/4% potassium 

permanganate solution for the removal of mercury. 

The sixth impinger contained a pre-weighed amount 

of silica gel to remove any residual moisture present 

in the gas stream. Following the impinger system, the 

gas was drawn through a dry gas meter, a calibrated 

orifice, and a leak-free pump.

Recovery procedures for the multiple metals train at 

the conclusion of the run were:

1. Remove the sampling train to the recovery site.

2. Note the condition of the train (i.e. filter 

condition, impinger contents' color, silica gel 

color, etc.). 

3. Disassemble the filter housing and transfer the 

filter to its original petri dish (Container #1). 

Transfer any particulate matter and filter fibers

which adhere to the filter holder and gasket to the 

petri dish also. Seal the container with Teflon tape 

and label it with the appropriate sample 

information.

4. Brush and rinse three times with acetone the 

front-half of the train (nozzle, probe, and fronthalf filter housing) into a precleaned container. 

Repeat the rinse procedure three times. Seal and 

label the container (Container #2).

5. Rinse the front-half of the train three times with a 

0.1N HNO3 solution (nozzle, probe and front-half 

filter housing) into a precleaned container. Seal 

and label the container (Container #3).

6. Measure the volume of or weigh the first, second, 

and third impingers to the nearest +/- 0.5 ml/g. 

Transfer the combined liquid to a precleaned 

sample container (Container #4). Rinse the 

connecting glassware, back half of filter housing 

and impingers with 0.1N HNO3 water and transfer 

the rinsate to Container #4. Seal and label the 

sample bottle with the appropriate information.

7. Measure or weigh the volume in the fourth and 

fifth impinger to the nearest +/- 0.5 ml/g. 

Transfer the combined liquid to a precleaned 

sample container (Container #5). Rinse the 

impingers with permanganate solution and again 

with water and placed in Container #5

8. Rinse fourth and fifth impingers with 8N HCl and 

transfer the rinsate to another container 

(Container #6). Seal and label the sample bottle 

with the appropriate information.

9. Return the silica gel in the last impinger to its 

original container (Container #7) and weigh to 

obtain a final weight the nearest +/- 0.5g. 

10. All containers were checked to ensure they are 

sealed, labeled, and all liquid levels are marked. 

All samples were logged onto the chain-ofcustody form. The samples remained chilled until 

analysis. Metals samples were delivered to 

Maxxam Analytics of Burlington, Ontario for 

analysis.

3.5.1 Metal and PM Emissions QA/QC Procedures

Field Blank Train - Field bias blanks and reagent 

blanks were collected at the end of the sampling 

program. The field bias blank consisted of preparing 

a metals train identical to the one used to conduct the 

sampling. 

Laboratory Method Blank – A method blank was 

prepared by the analytical laboratory, Maxxam 

Analytics, and analyzed in the same manner as the 

field samples.

3.6 PCDD/DF, PCB, AND PAH TEST METHOD

PCDD/DF, PCB, and PAH emissions testing was 

conducted following procedures outlined in California 

Air Resources Board (CARB) Methods 428 and 429 

using a single sample train and XAD resin trap. The 

sample train consisted of a heat-traced probe with a 

borosilicate buttonhook nozzle, and an attached 

thermocouple and Type-S pitot tube. The glass probe 

was maintained at a temperature of 250oF ± 25oF. 

After the probe, the gas passed through a heated glass 

fiber filter. Downstream of the heated filter, the 

sample gas passed through a water-cooled module, 
EAST PLANT 14 DOWNCOMER AND FTC SCRUBBER EXHAUSTS

I:\Alcoa.11423\50471.Source-Testing\Docs\Reports\Alcoa ICR East Plant_Final Report.docx

then through a sorbent module containing the XAD-2 

sorbent resin. The XAD module, which was kept at a 

temperature below 20oC, was followed by a series of 

four impingers. The XAD inlet temperature was 

monitored to ensure that the proper temperature was 

maintained. 

The first impinger, which acted as a condensate 

reservoir, was connected to the outlet of the XAD 

module and was modified with a short stem so that 

the sample gas will not bubble through the collected 

condensate. The first and third impingers were each 

empty. The second impinger contained 100 mls of 

HPLC Grade or better water and the fourth impinger 

contained a pre-weighed amount of silica gel. All 

connections within the sample train were either glass 

or Teflon; no sealant greases were used. The 

impingers were followed by a pump, dry gas meter, 

and a calibrated orifice meter.

Sampling was conducted isokinetically with readings 

of the flue gas parameters recorded at every sampling 

point during the traverse. Sampling was conducted at 

twenty-four sampling points (twelve points on each 

diameter) for at least 15 minutes per point to ensure 

that a minimum of 3 cubic meters (106 ft3) was 

collected during each test run. Each test run was a 

240 minutes in duration. 

Prior to sampling all sample train glassware was

prepared in accordance with Section 3A of the Manual 

of Analytical Methods for Analysis of Pesticide 

Residues in Human and Environmental Samples. Prior 

to use all glassware was rinsed with acetone, hexane 

and methylene chloride.

Leak checks on the sampling train were conducted 

before and after each test run. A mid test leak check 

was also conducted upon moving the sample train to 

each sample port. The sample train leak checks and 

leakage rates were documented on the field test data 

sheet for each respective run. 

Sample Recovery

Following completion of each test run the Method 

428/429 sample train was transported to a recovery 

area on-site. The recovery procedures for the sample 

train were as follows:

1. At the end of sampling, remove probe from the 

stack and cap the nozzle. Allow the train to cool 

briefly.

2. Conduct a leak check to ensure a leakage rate of 

<0.02 cfm.

3. The sample probe, nozzle and front-half of the 

filter holder was brushed and rinsed three times 

each with acetone (Container #1). Following the 

acetone rinse all components were rinsed three 

times with toluene and placed in Container #1.

4. Disassemble the filter housing and transfer the 

filter to its original glass petri dish with hexane 

rinsed forceps (Container #2). Transfer any 

particulate matter and filter fibers, which adhere 

to the filter holder and gasket to the petri dish 

also. Seal the container with Teflon® tape and 

label it with the appropriate sample information.

5. The XAD module was removed from the train and 

was sealed immediately (Container #3). The trap 

was covered in aluminum foil to minimize the 

exposure to light and was kept cold until the time 

of analysis

6. Measure the contents of the first impinger. Rinse 

the back-half filter housing, connecting line 

between filter holder and XAD condenser and the 

first impinger itself three times with acetone, 

followed by three rinses with toluene into the 

same container (#4). Note the XAD condenser 

was soaked a minimum of 5 minutes with toluene 

as part of the recovery process.

7. Measure the volume of water in the first and 

second impinger for moisture determinations and 

place in Container #5. Rinse the impingers and 

connecting glassware three times each with 

acetone and toluene and place in Container #5.

8. Place the contents of the fourth impinger into its 

original container and reweigh to obtain net 

moisture weight gain (Container #7) to the 

nearest ± 0.5 g.

9. All containers were checked to ensure they are 

sealed, labeled and all liquid levels are marked. 

All samples were logged onto the chain-ofcustody form. The samples remained chilled until 

analysis. Analysis were conducted using high 

resolution mass spectrometry (HR/MS).

PCDD/DF, PCB, and PAH samples were delivered 

to SGS Analytical Perspectives of Wilmington, 

North Carolina for analysis. 

3.6.1 PCCD/DF, PCB, and PAH QA/QC Procedures

Field Blank Train – Field bias blanks and reagent 

blanks were collected at the conclusion of the 

sampling program. The field bias blank consisted of 

preparing a Method 428/429 train identical to the 

ones to be used for sampling. The train was leak 

checked on the stack and then was recovered 

following Steps 1 through 9 above.

6 | FINAL: JULY 18, 2013 

I:\Alcoa.11423\50471.Source-Testing\Docs\Reports\Alcoa ICR East Plant_Final Report.docx

Spiked Sampling Trains – Each XAD module was 

spiked with known amounts of labeled internal 

standards in accordance with specified method 

procedures . Acceptable recovery of these standards 

is between 60 percent and 120 percent of the known 

value.

Laboratory Method Blank – A sample of the resin used 

to charge the XAD module was analyzed in the same 

manner as the field samples. The laboratory method 

blank was also spiked with known amounts of labeled 

internal standards. The laboratory method blank 

must not exceed the practical quantitation limit (PQL) 

or contain more than 5 percent of the analyte 

concentrations found in the field samples.

Laboratory Control Sample – The laboratory prepared 

spiking solutions from stock standards independent 

from the standards used for instrument calibration. 

Resin samples were spiked with these solutions and 

analyzed in the same manner as the samples to 

demonstrate the ability to generate acceptable test 

data. Acceptable accuracy of the laboratory control

samples is 50 percent to 150 percent recovery. Note 

that no USEPA audit sample or analysis were collected 

or analyzed as part of this testing. 

3.7 HEXAVALENT CHROMIUM TEST METHOD

Hexavalent chromium emissions were evaluated in 

accordance with SW-846 Method 0061 procedures 

(recirculation method). The sample train consisted of 

a borosilicate glass nozzle, an unheated borosilicate 

glass-lined probe, a recirculatory pump assembly 

consisting of Teflon® recirulationline and connectors, 

five chilled impingers, and a metering console. To 

eliminate the possibility of hexavalent chromium 

reduction between the nozzle and impinger the KOH 

absorbing solution was recirculated from the first 

impinger through the center of the probe to the 

nozzle at a rate of 50 ml/min. Sample gas was drawn 

through the nozzle and probe isokinetically through a 

series of five impingers containing the reagents 

prescribed by the method. The first impinger was

constructed of Teflon® and contained 140 mls of 0.1M 

KOH solution. The second and third impingers were

constructed of Teflon® andcontained approximately 

80 mls each of 0.1M KOH. The fourth impinger was

constructed of Teflon® and was empty to catch any 

overflow from the first three impingers. The fifth

impinger was constructed of borosilicate glass and 

contain a pre-weighed amount of silica gel to remove 

any residual moisture present in the gas stream. 

Following the impinger system, the gas was drawn 

through a dry gas meter, a calibrated orifice, and a 

leak-free pump. 

Sample Recovery

Recovery procedures for the hexavalent chromium

train at the conclusion of the run were:

1. At the end of sampling, remove probe from the 

stack and cap the nozzle. Allow the train to cool 

briefly.

2. Conduct a leak check to ensure a leakage rate of 

<0.02 cfm.

3. Evaluate the pH of the reagent in the first 

impinger utilizing a pH indicator strip. If the pH 

of the first impinger is <8.5, the test run was

voided and the use of 0.5 M KOH as the absorbing 

reagent was substituted for the 0.1M KOH 

solution in the impingers for the subsequent test 

runs. If the pH is >8.5 the sample train was

transported to a recovery area on-site. Note that 

the post test pH of all sample trains were >8.5.

4. A post test nitrogen purge of the sample train was

conducted for one-half hour period at a flow rate 

of 10L/min as a means of SO2 removal from the 

impinger contents.

5. Measure the volume of or weigh the first, second, 

third and fourth impingers to the nearest +/- 0.5 

ml/g. Rinse four times with deionized water the 

glass nozzle, probe, recirculationlines, connecting 

tubing and impingers. Transfer the combined 

liquid to a precleaned polyethylene container 

(Container #1). Immediately after recovery the 

sample was filtered to remove any insoluble 

matter. The sample was filtered utilizing a 

nitrogen gas pressure assisted filtration process 

in a Teflon® reservoir through a 0.45 micromteter 

acetate filter (or equivalent) and collected into a 

1000 mL graduate cylinder. Additionally, 

Container #1 and the Teflon® reservoir were

rinsed three times separately with deionized 

water and passed through the filtration system. 

The final volume of the filtrate and rinses was

recorded and the combined liquid was

transferred back to Container #1. Seal the 

container with Teflon tape and label it with the 

appropriate sample information. The Teflon®

reservoir was then rinsed once with 0.1M HNO3 

followed by a deionized water rinse. Please note 

that total chromium was not analyzed and these 

rinses along with the acetate filter were

discarded.

6. Return the silica gel in the last impinger to its 

original container (Container #2) and weigh to 

obtain a final weight the nearest +/- 0.5g. 

7. At this point, all containers were checked to 

ensure they are sealed, labeled and all liquid 

levels are marked. All samples were logged onto 

the chain-of-custody form. The samples remained

chilled until analysis. Hexavalent chromium

samples were delivered to Maxxam Analytics of 

Burlington, Ontario for analysis.

3.7.1 Hexavalent Chromium Emissions QA/QC 

Procedures

Field Blank Train – Field bias blanks and reagent 

blanks were collected at the end of the sampling 

program. The field bias blank consisted of preparing 

a metals train identical to the one used to conduct the

4. RESULTS, DISCUSSIONS AND CONCLUSIONS

The results of the test program are presented in 

Tables 1 through 10. The following section briefly 

discusses the results. Field data sheets and emission 

calculations are presented in Appendix C. Laboratory 

data is presented in Appendix D.

4.1 PCCD/DF EMISSION TEST RESULTS (TABLES 1 

AND 6)

Tables 1 and 6 contain the results of the PCDD/DF 

testing on the FTC scrubbers and the Line 3 Potline, 

respectively. A review of Table 1 indicates that the 

total PCDD/DF emissions normalized to aluminum 

production rate averaged < 1.34E-09 lb/ton of 

aluminum (lb/ton Al) for both scrubbers combined 

(TEQ Equivalent). Note that this average result was 

obtained by averaging the first two test runs that 

were conducted on the South FTC scrubber and 

adding it to the third test run which was conducted on 

the North FTC scrubber. Note also that any PCDD/DF 

cogeners that were below analytical detection limits 

were included in the totals with the detection limit 

used for the sample result. A less than sign “<” was 

then included in the overall sample total. 

PCDD/DF emission results from the Line 3 Potline are 

summarized in Table 6. As can be seen in Table 6 the 

PCDD/DF emissions normalized to production rate 

ranged from <1.06E-08 lb/ton Al to <2.52E-08 lb/ton 

Al (TEQ Equivalent) and averaged <1. 75E-08 lb/ton 

Al. Note that these mass emission rates were 

obtained by using the total Line 3 Potline volumetric 

flow rate. 

4.2 PAH EMISSION TEST RESULTS (TABLES 2 AND 7)

Tables 2 and 7 contain the results of the PAH testing 

on the FTC scrubbers and the Line 3 Potline, 

respectively. A review of Table 2 indicates that the 

total PAH emissions normalized to aluminum 

production rate averaged 1.21E-01 lb/ton of 

aluminum (lb/ton Al) for both scrubbers combined. 

Note that this average result was obtained using the 

procedures outlined above in Section 4.1. 

PAH emission results from the Line 3 Potline are 

summarized in Table 7. As can be seen in Table 7 the 

PAH emissions normalized to production rate ranged 

from 2.53E-01 lb/ton Al to 2.97E-01 lb/ton Al and 

averaged 2.79E-01 lb/ton Al. Note that these mass 

emission rates were obtained by using the total Line 3 

Potline volumetric flow rate. 

4.3 PCB EMISSION TEST RESULTS (TABLES 3 AND 8)

Tables 3 and 8 contain the results of the PCB testing 

on the FTC scrubbers and the Line 3 Potline, 

respectively. A review of Table 3 indicates that the 

total PCB emissions normalized to aluminum 

production rate and using WHO toxic equivalency

factors averaged 1.54E-10 lb/ton of aluminum (lb/ton 

Al) for both scrubbers combined. Note that this 

average result was obtained using the procedures 

outlined above in Section 4.1. 

PCB emission results from the Line 3 Potline are 

summarized in Table 8. As can be seen in Table 7 the 

PCB emissions normalized to production rate ranged 

from 1.95E-09 lb/ton Al to 2.62E-09 lb/ton Al and 

averaged 2.36E-09 lb/ton Al. Note that these mass 

emission rates were obtained by using the total Line 3 

Potline volumetric flow rate. 

4.4 METAL AND PM EMISSION TEST RESULTS 

(TABLES 4 AND 9)

PM emissions from the FTC Scrubber exhaust are 

summarized in Table 4A. FTC Scrubber total PM 

emissions were very low with a total mass emissions 

rate of 1.70 lb/ton Al during the three test runs 

conducted. 

As can be seen in Table 4B, the metal with the most 

significant emission rate from the scrubber exhaust 

was nickel. Normalized mass emission rate of nickel 

was 1.59E-03 lb/ton Al for the three test runs 

conducted. Concentrations of antimony, beryllium, 

cadmium, and selenium were all below analytical 

detection limits. The same procedure used to 

determine total PCDD/DF scrubber emissions were 

used to determine metal emission rates.

PM emissions from the Line 1 Potline exhaust are 

summarized in Table 9A. PM emissions from the 

potline exhaust, prorated to the total potline flow rate

averaged approximately 11.3 lb/ton Al during the 

three test runs conducted. 

Metal emissions from the Line 1 Potline are included 

in Table 9B. The metals with the most significant 

emissions from the Line 1 Potline were nickel and 

chromium which averaged 4.83E-02 and 1.34E-02

lb/ton Al, respectively for the three test runs 

conducted (prorated for total potroom flow rate).

4.5 HEXAVALENT CHROMIUM EMISSION TEST 

RESULTS (TABLES 5 AND 10)

As can be seen in Table 5, hexavalent chromium 

normalized emissions from the FTC scrubbers 

averaged <4.57E-05 lb/ton Al. The same procedure 

used to determine total PCDD/DF scrubber emissions 

were used for determining total hexavalent chromium 

emissions. Similar to the PCDD/DF calculations, the 

detection limit was used as the sample values when 

totaling process emission rates.

Hexavalent chromium emissions from the Line 1 

Potline are included in Table 10. Hexavalent 

chromium normalized emissions from the Line 1 

Potline averaged <2.32 E-04 lb/ton Al for the three 

test runs conducted (prorated for total potroom flow 

rate).

4.6 CONCLUSIONS 

All testing proceeded smoothly with no process 

operating or sampling problems encountered. Sample 

train leak checks were within specified parameters 

and isokinetic sampling rates were within specified 

criteria (90 to 110 percent) during all three test runs

for each pollutant tested.

5. QUALITY ASSURANCE/QUALITY CONTROL

QA/QC was based on the recommended QA/QC 

procedures of the various sampling and analytical 

methods that were used for the compliance test. 

The sampling equipment calibration documentation 

are provided in Appendix E. This section 

summarizes the pertinent QA/QC procedures that 

were employed during the emissions testing 

program.

5.1 EQUIPMENT CALIBRATION

Calibration of equipment was conducted in 

accordance with the procedures outlined in the 

USEPA document entitled "Quality Assurance 

Handbook for Air Pollution Measurement Systems; 

Volume III—Stationary Source Specific Methods" 

(EPA-600/4-77-027b). Equipment calibration was 

performed in accordance with USEPA guidelines 

and/or manufacturer’s recommendations. 

Documentation of all calibrations is presented in 

Appendix D. Examples of field equipment used and 

typical calibration requirements follows:

» Probe nozzles (QA Handbook Section 3.4.2, pg. 

19) - make three measurements of the nozzle ID 

(to the nearest 0.001 in.) using different 

diameters with a micrometer. Difference 

between the high and low values should not 

exceed 0.004 in. Post-test check - inspect for 

damage.

» Pitot tubes (QA Handbook Section 3.1.2, pp. 1-

13) - measured for appropriate spacing and 

dimensions or calibrate in a wind tunnel. 

Rejection criteria given on the calibration sheet. 

Post-test check - inspect for damage.

» Thermocouples (QA Handbook Section 3.4.2, 

pp. 15-18) - verify against a mercury-in-glass 

thermometer at two or more points including 

the anticipated measurement range. Acceptance 

limits - impinger ±2°F; DGM ±5.4°F; stack ±1.5 

percent of stack temperature

» Dry gas meters (QA Handbook Section 3.4.2, pp. 

1-12) - Dry gas meters are calibrated using 

critical orifices. The procedure entails four runs 

using four separate critical orifices running at 

an actual vacuum 1-2 in. greater than the 

theoretical critical vacuum. The minimum 

sample volume required per orifice is 5 ft3. 

Meter boxes are calibrated annually and then 

verified by use of the alternative Method 5 posttest calibration procedure. This procedure is 

referenced as Approved Alternate Method ALT009 (June 21, 1994) by EPA’s Emission 

Measurement Center. The average Y-value 

obtained by this method must be within 5% of 

the initial Y-value.

» Field barometer (QA Handbook Section 3.4.2, 

pp. 18-19) - compare against a mercury-in-glass 

barometer or use Airport Station BP and correct 

for elevation. Acceptance criteria - ± 0.02 in. Hg; 

post-test check - same.

5.2 LABORATORY QA/QC PROCEDURES 

Laboratory analysis utilizes a number of different 

types of QA/QC checks to document the validity of 

the generated data. Internal QA/QC procedures 

were conducted by the laboratory in accordance 

with individual method requirements. These 

specifications include the types of QA/QC checks 

required, the frequency of each check, and the 

QA/QC acceptance criteria for these checks.

The laboratory documents that both initial and 

ongoing instrument and analytical functions have 

been met. Sample analyses did not proceed unless 

these calibration requirements were met.

5.3 LEAK CHECKS

Pitot tube leak checks were conducted in 

accordance with USEPA RM 2. Leak checks were 

conducted on the isokinetic sampling train prior to 

and following each test run in accordance with 

procedures specified in each test method.

5.4 CHAIN OF CUSTODY DOCUMENTATION

Chain of custody forms were completed for samples 

delivered to the laboratory. Copies of the completed 

chain-of-custody forms are included with the 

laboratory reports (Appendix D).

5.5 BLANK SAMPLES

Field blanks were collected for each sample train in 

accordance with specified method procedures. A 

field blank of the acetone used to recover the USEPA 

RM 5 sample train was analyzed to determine 

sample contamination. The results of the blank 

were used to adjust field sample results in 

accordance with the method. The blank correction 

weight for the acetone used does not exceed 0.001 

percent of the weight of the acetone blank, as 

described in Section 12.8 of USEPA RM 5.
