MEMORANDUM 

SUBJECT: Test Report 85 CHM11 (Carolina Platers) 

FROM: Frank R. Clay^<L _ 

TO: Al Vervaert 

Prior to the recent test work performed in Greenville, SC at Roll 

Technology Corp. (formerly Carolina Platers), I reviewed test report 

85 CHM11 for various stack parameters. During the review, I discovered 

that the contractor performed outlet calculations using an incorrect stack 

diameter. The diameter used was 21.25 Inches and should have been 22.25 

inches. This, of course, means that the hourly emission rates are biased 

low by about 9%. With the exception of gr/dscf on Mg/M3, all emission 

rates pertaining to the outlet are erroneous. 

I have attached two sampling summary sheets that provide correct 

numbers for both inlet and outlet locations. These should probably be 

placed into the Docket with the report so that the correct numbers are 

available. 

Since the original outlet numbers are incorrect, scrubber efficiencies 

based on these numbers are also incorrect. When looking at the chromium 6 

catches and comparing them with total chromium numbers, 1t appears that 

the samples are not truly representative of a plating operation. The 

Cr1"

6 and total chromium valves should be almost identical. In this test, 

the total chromium 1s 2 to 4 times as large as the Cr"*"6. I discussed this 

with J. F. Tucker at Roll Technology Corp., and his opinion was that it 

was not possible to plate successfully using a plating bath with those 

ratios of Cr*6 and total chromium. 

Why the chromium results from the first Greenville test are out of 

proportion is still unexplained. Conversion from Cr**' to Cr*3 with the 

passing of time may be a possibility. While the Cr-*"6 numbers are suspect, 

the total chromium numbers appear to be more accurate. 

If total chromium concentrations are used to calculate the scrubber 

efficiency, the efficiency comes out to be 92.5% for the May 1985 test. 

In our most recent test of the same control device (September 1987), we 

have calculated a scrubber efficiency of 92.55%. This most recent calculation is based upon Crt6 concentrations that were obtained at the site -

the analysis taking place within an hour after sample recovery had been 

completed. 

We do not have total chromium concentrations for the 1987 test. If 

you would like these numbers, I suggest that you request the analysis in 

a memo to George Walsh.

1.0 INTRODUCTION 

During the week of May 13-17, 1985, the Emission Measurement Branch of the 

U. S. Environmental Protectio n Agency conducted an emission measurement program 

a t Carolina Plating Company's plating plant locate d i n Greenville , South 

Carolina . The purpose of this program was t o provide data fo r a screening 

study t o determine the quantit y and fonn of chrcmiun emissions associate d with 

hard chrcmiun plating . 

Comprehensive testing was conducted on a serie s of chrcmiun plating tanks 

a l l of whose emissions ar e controlle d by a singl e packed-bed wet scrubber . 

This fune scrubbe r controlling emissions from hard chrcmiun plating tanks 

No. 1, 2, 3 , and 7 a t the plant was selecte d fo r sourc e testing fo r the 

following reasons: 

Carolina Plating applie s hard chromium plat e t o larg e industria l 

rollers . Typicall y the roller s remain i n the tanks fo r 12 t o 36 

hours, depending on the dimensions of the roller s and the 

chrcmiun plat e thickness required. Although ther e is no 

industr y wide "typical" par t tha t receive s hard chrcmiun plate , 

i t is not unusual fo r job shops t o plat e industria l rollers . 

The advantages of performing a sourc e tes t on a tank used fo r 

plating roller s instea d of othe r type s of metal parts are : 

a) the long plating time accommodates continuous testing , b) the 

amount of chrcmiun deposite d during the tes t can be easil y 

determined, and c) the surfac e area plate d can be easil y 

determined. 

The plating tanks appear t o be typica l of othe r hard chrcmiun 

plating tanks in the electroplating industry , based on operating 

parameters such as current, voltage , plating time , and chromic 

aci d concentration. The tanks ar e situate d with the longest 

dimension in the vertica l direction, which is common fo r tanks 

tha t ar e used t o plat e larg e industria l rollers. There ar e no 

demisting agents used in the plating tanks. The use of 

demisting agents is not common practic e fo r hard chrcmiun 

platers.

This report is organized into several sections addressing various aspects 

of the testing program. Immediately following this introduction is the 

"Process Operation" section which includes a description of the process and 

control device tested. Following this is the "Summary of Results" section 

which presents table summaries of the test data and discusses these results. 

The next section, "Sampling Locations and Test Methods" describes and 

illustrates the sampling locations for emissions testing and grab sampling and 

then explains the sampling strategies used. The final section, "Quality 

Assurance," notes the procedures used to ensure the integrity of the sampling 

program. The Appendices present the complete Test Results and Example 

Calculations (Appendix A) ; Field and Analytical Data (Appendix B) ; Sampling and 

Analytical Procedures (Appendix C) ; Calibration Data (Appendix D) ; MRI Process 

Data (Appendix E) ; and Test Participants and Observers (Appendix F) .

composition of the plating solution remains constant, the operating 

voltage and current vary with each roll that is plated. 

2.2 AIR POLLUTION CONTROL 

All four tanks are equipped with hoods on three sides to capture the 

chromic acid mist generated during the plating process. A plan view of 

the exhaust system 1s shown in Figure 2-2. Emissions that are captured by 

the exhaust system are treated by a fume scrubber located on a mezzanine 

adjacent to the plating area. The scrubber 1s a double packed-bed type 

manufactured by Napco, Incorporated (Model No. MA-101). Each bed contains 

30 cm (l2-1nches) of polypropylene packing. The beds are sprayed 

continuously with water, which drains Into a holding tank and 1s 

recirculated through the scrubber. The holding tank 1s flushed and filled 

with clean water about 3 times a day. The. spent liquid 1s either used as 

make-up solution for the plating tanks or is treated on site in a 

wastewater treatment system. 

The scrubber also contains a mist elimination stage for the removal 

of water droplets entrained in the exhaust gas stream. This stage 

consists of a "Chevron-type" arrangement of baffles that changes the 

direction of gas flow four times at 30°-angles. The entire scrubbing unit 

has a design control efficiency of 96 to 99 percent for the removal of 

chromic acid. 

The exhaust fan, which is located immediately downstream of the 

scrubber, is manufactured by Ouall Industries, Incorporated (Model 

No. NH-66). The fan is rated at 9.4 cubic meters per second (m3/s) 

(20,000 standard cubic feet per minute [scfm]) for air at 21°C (70°F); 

however, a gas flow of 4.7 m3/s (10,000 scfm) was measured during the test 

series. Exhaust gases exit through a short stack located on the roof. 

2.3 PROCESS CONDITIONS DURING TESTING 

Process operating parameters such as plating solution temperature, 

operating voltage, and operating current were monitored and recorded 

during each test run. Copies of the actual data sheets are presented in 

Appendix E. Also recorded were descriptions (dimensions and surface area) 

and plating requirements (current and plating time) of each individual job 

or item being plated during each test run. This information was obtained

from log sheets maintained by plant personnel and 1s also presented in 

Appendix E. No operating parameters were monitored for the scrubber; 

however, there were no indications of any malfunction 1n the system during 

the testing period. 

Test run Nos. 1 and 3 were performed without Interruption. Test run 

No. 2 was suspended at one point because the production rate 1n the tanks 

was significantly lower than normal. Testing was resumed after 1 hour 

when the production rate was increased. 

The total current supplied to the tanks during each test run 1s 

calculated 1n terms of ampere-hours and Included 1n Appendix E. A summary 

of the total current values is presented in Table 2-2.

3.0 SUMMARY OF RESULTS 

Particulat e matte r and experimental "mediun volune?' tests were conducted a t 

t he inle t and the outle t of the packed-bed wet scrubbe r controlling chrcmiun 

plating tanks No. 1, 2, 3 , and 7 . Table 3.1 sunmarizes the testing schedule . 

In brief , from the results of the Method 5 testing , the uncontrolled 

emissions from the tanks averaged 0.2 2 pounds pe r hour of particulat e matter , 

0.025 pounds pe r hour of hexavalent chrcmiun, and 0.05 2 pounds pe r hour of 

tota l chrcmiun. The controlle d emissions averaged 0.11 pounds pe r hour of 

particulat e matter , 0.001 pounds pe r hour of hexavalent chrcmiun, and 0.00 4 

pounds pe r hour of tota l chrcmiun. The resulting collectio n efficienc y of the 

we t scrubbe r was 43.5% fo r particulat e matter , 95.7% fo r hexavalent chrcmiun, 

and 93.0% fo r tota l chrcmiun. The "mediun volune" testing results ar e not 

include d in the sunmary of results sinc e this is a screening technique . These 

results ar e discusse d separatel y in Sectio n 3.4 . 

In the following sections, the results addressed above and additiona l 

results ar e presented and discusse d i n detail according t o the emission type 

and sampling location. The ccmputer printouts of the emission calculations ar e 

can be found in Appendix A. The origina l fiel d data sheets and the analytica l 

data ar e locate d i n Appendix B. 

3.1 PARTICULATE MATTER, HEXAVALENT CHROMIUM, AND TOTAL CHROMIUM 

Particulat e matte r tests (EPA Method 5) along with the determination of the 

associate d flue gas flow rate s were conducted a t both the scrubber inle t and 

outlet . The particulat e matte r samples were initall y analyzed using 

gravimetri c technique s t o determine the mass of particulat e matter . Then the 

3-1 
P.17 

samples were further analyzed for hexavalent and tota l chromium. Complete 

descriptions of each sampling location and the sampling and analytical 

procedures are given in Chapter 4 (and Appendix C). 

3.1.1 Scrubber Inle t 

The scrubber inle t represents the uncontrolled emissions from plating tanks 

No. 1, 2, 3, and 7 . The circular horizontal inle t duct was only traversed in 

one direction during the particulate sampling. The singl e traverse was 

utilized because of the difficult y in gaining access to the duct and because 

the very fine acid mist particle s present in the duct would be expected to 

behave like a gas resulting in a uniform cross-sectional particl e distribution. Prior t o the Method 5 testing at the scrubber inlet, a pito t traverse 

was conducted along two axes. Since the pito t traverse showed flow rates only 

slightl y less (1%) than the Method 5 sampling, the Method 5 test data was used 

in the calculations and is presented in the sunmary tables. 

Flue Gas Conditions and Isokineti c Sampling Rate - A sunmary of the flue 

gas conditions at the scrubber inle t and outle t is presented in Table 3.2. The 

volumetric flow rates were fairl y consistent and averaged 16,500 actual cubic 

meters per hour (582,000 actual cubic fee t per hour). The flow rate at the 

inle t was approximately 13% lower than the outle t flow rate; this was likel y 

due to measurement error in the outle t flow rate measurements which were 

conducted in nonparallel flow. 

The flue gas tenperature averaged 28°C (82°F), with a moisture content 

of 1.5 percent. The oxygen, carbon dioxide, and carbon monoxide content was 

that of ai r at 20.9, 0.0, and 0.0 percent, respectively. The volunetric flow 

rate at standard conditions averaged 15,200 dry standard cubic meters per hour 

3-3 
P.18 

(540,000 dry standard cubic fee t per hour). Standard conditions are 20°C 

(68°F), 760 mm Hg (29.92 in. Hg), and dry. The isokineti c sampling rate was 

within the allowable range for al l three sample runs. 

Particulat e Emissions - The particulate emissions from the plating tanks 

(see Table 3.3) were variable. The particulat e emissions for the inle t runs 

averaged 6.37 milligrams per dry standard cubic meter (0.0028 grains per dry 

standard cubic foot) and 0.097 kilograms per hour (0.22 pounds per hour). 

Hexavalent Chromium Emissions - The hexavalent chrcmiun emissions for each 

test run (see Table 3.3) were consistent with the corresponding particulate 

run. They averaged 119, 95, and 127 milligrams of hexavalent chrcmiun per gram 

of particulat e emissions for runs 1-1, 1-2, and 1-3, respectively. The 

hexavalent chrcmiun emissions for the inle t tests averaged 0.7 36 milligrams per 

dry standard cubic meter (0.00032 grains per dry standard cubic foot) and 

0.0113 kilograms per hour (0.025 pounds per hour). 

Total Chromium Emissions - The total chrcmiun emissions for each test run 

(see Table 3.3) were consistent with the corresponding particulat e run and 

averaged 249, 207, and 260 milligrams of tota l chrcmiun per gram of particulate 

emissions for runs 1-1, 1-2, and 1-3 respectively. The total chrcmiun 

emissions for the inle t tests averaged 1.54 milligrams per dry standard cubic 

meter (0.00067 grains per dry standard cubic foot) and 0.024 kilograms per hour 

(0.052 pounds per hour). 

3.1.2 Scrubber Outlet 

The scrubber outle t represents the controlled emissions frcm plating tanks 

No. 1, 2, 3, and 7. Some nonparallel (cyclonic or swirling) flow was present 

in the scrubber outle t stack. To estimate the effec t of these flow conditions 

3-5 
P.19 

on the sampling data, the angle of misalignment was determined at each sampling 

point during a preliminary pito t traverse. Application of these angles to the 

pito t traverse data resulted in a flow rate about 10% lower than the measured 

inle t values. Thus, the flow rate data for each Method 5 test was used in the 

calculations and is presented in the sunmary tables. 

Flue Gas Conditions and Isokineti c Sampling Rate - A sunmary of flue gas 

conditions at the scrubber outle t is presented in Table 3.2 . The volunetric 

flow rates for the three outle t runs were very consistent. The outle t 

volumetric flow rate averaged 18,900 actual cubic meters per hour (667,000 

actual cubic fee t per hour) with a flue gas temperature of 27°C (81°F) and 

a moisture content of 2.0 percent. The oxygen, carbon dioxide, and carbon 

monoxide concentrations were that of ambient ai r at 20.9, 0.0, and 0.0 percent, 

respectively. The volunetric flow rate at standard conditions averaged 17,600 

dry standard cubic meters per hour (621,000 dry standard cubic fee t per hour). 

Standard conditions are 20°C (68°F), 7 60 mm Hg (29.92 in. Hg), and dry. 

These flow rate measurements are likel y to be biased high due to the 

nonparallel flow conditions. 

The isokineti c sampling rates were well within the allowable range for al l 

runs. 

Particulate Emissions - The particulat e emissions from the control equipment to the atmosphere were variable (see Table 3.3) with al l runs being within 

approximately 20% of the averages. Over al l three runs, the particulat e emissions 

averaged 2.94 milligrams per dry standard cubic meter (0.00128 grains per dry 

standard cubic foot) and 0.052 kilograms per hour (0.114 pounds per hour). 

Hexavalent Chromium Emissions - The hexavalent chrcmiun emissions for each 

test run were fairl y consistent with thei r corresponding particulat e run and 

averaged 10.0, 5.9, and 10.8 milligrams of hexavalent chrcmiun per gram of

Sample preparation methods are as follows: 

1 = For the htethod 5 and thimble filters: Hexavalent chromium was extracted from the filter, acetone rinse, (and water rinse for Mathod 5 filters) 

and the filtrate from this process was analyzed for Cr . The residue from the extraction was analyzed for total chromium. Total chromium 

results reported (mg) are the sum of both measurements (blank corrected). 

2 = For impinger contents: The liquid samples were concentrated; one measured aliquot was taken for hexavalent chromium analysis and one measured 

aliquot taken for total chromium analysis. Chromium concentrations are expressed as mg Cr per g of particulate matter catch.

4.5 PARTICULATE MATTER 

Method 5, as described in the Federal Register,* was used to measure 

particulate grain loading at locations A and B. All tests were conducted 

isokinetically by traversing the cross-sectional area of the stack and 

regulating the sample flow rate relative to the flue gas flow rate as measured 

by the pitot tube attached to the sample probe. A sampling train consisting of 

a heated, glass-lined probe, a heated 7 9 mm (3 inch) diameter glass fiber 

filter (Reeve Angel), and a series of Greenburg-Smith impingers was employed 

for each test. An acetone rinse and a water rinse of the nozzle, probe, and 

filter holder portions of the sample train were made at the end of each test. 

The acetone rinse and the particulate caught on the filter media were dried at 

room temperature, the water rinse was taken to dryness in an oven; all three 

were then desiccated to a constant weight, and weighed on an analytical 

balance. Total filterable particulate matter was determined by adding these 

three values. 

The "mediun volune?' (MV) sampling train was also used to measure 

particulate matter at locations A and B. MV sampling was conducted at a single 

sampling point. See Appendix C for detailed Method 5 and MV sampling 

procedures. 

4.6 HEXAVALENT CHROMIUM CONTENT 

Hexavalent chrcmiun content was determined utilizing procedures described 

in the tentative EPA Method "Determination of Hexavalent Chrcmiun Emissions 

from Stationary Sources" (see Appendix C) . The Method 5 filter catch collected 

and weighed for each Method 5 run was taken and analyzed for hexavalent 

chrcmiun content using this method. It was also used to deteimine the 

hexavalent chrcmiun content of the MV sampling train filter catch and the 

impinger contents.

5.0 QUALITY ASSURANCE 

Because the end product of testing is to produce representative emission 

results, quality assurance is one of the main facets of stack sampling. 

Quality assurance guidelines provide the detailed procedures and actions 

necessary for defining and producing acceptable data. One such document used 

in this test program to ensure the collection of acceptable data and to provide 

a definition of unacceptable data was the EPA Quality Assurance Handbook 

Volume III, EPA-600/4-77-027. 

Relative to this test program, EMB used the following steps to ensure that 

the testing and analytical procedures produce quality data. 

o Calibration of field sampling equipment (Appendix E) . 

o Checks of train configuration and on calculations. 

o Use of designated analytical equipment and sampling reagents. 

In addition, the analytical balance used for filter weighing by Entropy was 

audited with Class "S" weights. 

Audit solutions prepared by the EPA were used to check the analytical 

procedures of the laboratories conducting the hexavalent and total chromium 

analyses. Table 5.1 presents the results of these analytical audits. The 

audit tests show that the analytical techniques were good. 

T he sampling equipment, reagents, and analytical procedures for this test 

series were in compliance with all necessary guidelines set forth for accurate 

test results as described in Volume III of the Quality Assurance Handbook.

P.60 

DETERMINATION OF TOTAL PARTICULATE EMISSIONS 

All particulate samples were collected using an EPA Method 5 sampling 

train, and Method 5 sampling procedures, as described in the Federal Register*. 

SAMPLING APPARATUS 

The particulate sampling train used in these tests met design 

specifications established by the EPA. The sampling apparatus, which was 

assembled by Entropy personnel, consisted of the following: 

Nozzle - Stainless steel (316) with sharp, tapered leading edge and 

accurately measured round opening. 

Probe - Borosilicate glass with a heating system capable of maintaining a 

minimum gas temperature of 121°C (250°F) at the exit end during 

sampling. 

Pitot Tube - A type S pitot tube that met all geometric standards was 

attached to a probe to monitor stack gas velocity pressure. 

Temperature Gauge - A Palmer bimetallic coil thermometer was used to 

monitor stack gas temperature. 

Filter Holder - The filter holder was made of Pyrex glass, with heating 

system capable of maintaining a filter temperature of approximately 121°C 

(250°F). 

Filter - A 79-mm (3-in.) diameter glass fiber filter (Reeve Angel) was 

used. 

Draft Gauge - The draft was measured with an inclined manometer. 

Impingers - Four Greenburg-Smith design impingers were connected in 

series. The first, third, and fourth impingers were modified by removing 

the tip and extending the tube to within 1.3 cm (0.5 in.) of the bottom of 

the flask. 

Metering System - The RAC metering system consisted of a vacuum gauge, a 

leak-free pump, thermometers capable of measuring teraperature to within 

1.5°C (5°F), a calibrated dry gas meter, and related equipment, to 

maintain an isokinetic sampling rate and to determine sample volume.

ANALYTICAL PROCEDURES 

The following procedures were used and followed the methods described in 

the Federal Register*. 

Container No. 1 - The filter and any loose particulate matter from this 

sample container were placed into a tared glass weighing dish, desiccated 

for 24 hours to a constant weight, and weighed to the nearest 0.1 mg. 

Container No. 2 - The acetone washings were transferred to a tared beaker, 

evaporated to dryness at ambient teraperature and pressure, desiccated for 

24 hours to a constant weight, and weighed to the nearest 0.1 mg. 

Container No. 3 - The water washings were transferred to a tared beaker, 

evaporated to dryness in an oven, desiccated for 24 hours to a constant 

weight, and weighed to the nearest 0.1 mg. 

Container No. 4 - The acetone blank was transferred to a tared beaker and 

evaporated to dryness at ambient temperature and pressure. The blank was 

then desiccated for 24 hours to a constant weight and weighed to the 

nearest 0.1 mg. 

Container No. 5 - The impinger contents were marked with the sample run 

number and saved for chromium analysis. 

Container No. 6 - The distilled water blank was saved for chromium 

analysis. 

Container No. 7 - The unused glass fiber filter was treated in an identical 

manner as the filter in Container No. 1. 

The term "constant weight" referred to above means a difference of no more 

than 0.5 mg or 1 percent of total weight less tare weight, whichever is greater 

between two consecutive readings, with no less than 6 hours of desiccation 

between weighings. All analytical data were recorded on the analytical data 

sheets.

type 2 reagent - ASTM Test Method D 1193-77. Solutions were made as follows: 

Digestion Solution - 20.0 g of NaOH and 30.0 g anhydrous Na2C03 were 

dissolved in water in a 1-liter volumetric flask, and this solution diluted 

to the mark. It was stored in a tightly capped polyethylene bottle and was 

prepared fresh monthly. 

Potassium Dichromate Stock Solution - 141.4 mg of analytical reagent grade 

K2 Cr2 07 was dissolved in water, and this solution diluted to 1 liter 

(1 ml - 50 ug Cr + 6 ) . 

Potassium Dichromate Standard Solution - 10.00 ml of K2Cr207 stock solution 

was diluted to 100 ml (1 ml = 5 ug Cr ) with water. 

Sulfuric Acid - A ten percent (v/v) solution was made by diluting 10 ml H2S04 

to 100 ml in water. 

Acetone - Same as Method 5. 

Diphenylcarbazide Solution - 250 mg of 1, 5-diphenylcarbizide was dissolved 

in 50 ml acetone and stored in a brown bottle. The solution was discarded 

whenever it became discolored. 

Sample Preparation 

To prevent the possibility of sample deterioration, all samples were 

protected from extreme heat, were kept dry, and were analyzed within one month 

of collection. Sample preparation involved digestion and filtration. The 

contents of Container No. 2 (the acetone probe rinse) was placed in a 250 ml 

beaker and evaporated to dryness. Following this, the contents of Container 

No. 1 (with the filter cut into small pieces) was added to the beaker; 

digestion solution (40 ml) was added and the beaker covered with a watch 

glass. Using a hot plate, this solution was heated to near boiling with 

constant stirring for 30 minutes; it was not allowed to evaporate to dryness. 

The solution was then cooled and transferred quantitatively to the 

filtration apparatus with water. This apparatus consists of a vacuum unit 

constructed of plastic or glass which accommodates a 47 ram diameter, 3.0 um 

pore size Teflon filter. The solution was filtered and transferred 

quantitatively to a 100 ml volumetric flask which was then filled to the mark 

with water. 

C-9 
P.64 

Two equal volume aiiquots of the same sample solution were taken; each 

+6 contained between 30 and 50 yg of Cr (less if that was not possible). One 

of the aiiquots was spiked with an aliquot of standard solution containing 30 

+6 to 50 (ig of Cr . Then both the spiked and unspiked sample aiiquots were 

readied for measurement as described in the previous section. 

The Cr mass, C , in u? in the aliquot of the unspiked sample solution 

was then calculated using the following equation: 

C = C s a 

A s Equation C-1 

At ~ A s 

Where: 

+6 Ca =• Cr in the standard solution, u g. 

Ag = Absorbance of the unspiked sample solution. 

Afc » Absorbance of the spiked sample solution. 

Volume corrections were not required since the solutions as analyzed were 

made to the same final volume. When the results of the method of additions 

procedure used on the single source sample did not agree within 10 percent of 

the value obtained by the routine spectrophotometric analysis, all samples from 

the source were reanalyzed using the method of additions procedure. 

SPECTROPHOTOMETER CALIBRATION 

Calibration of the spectrophotometer involved two basic sets of operations 

and these are described below. 

Optimum Wavelength Determination 

Every 6 months, the wavelength scale of the spectrophotometer was 

calibrated using an energy source with an intense line emission or a series of 

glass filters spanning the measuring range of the spectrophotometer. The 

spectrophotometer was checked to see that the wavelength scale read within 

+5 nm at all calibration points. After confirming that the wavelength scale of 

C-11 
P.65 

Spectrophotometer Calibration Quality Control 

The absorbance value obtained for each standard was multiplied by the Kc 

factor (least squares slope) to determine the distance each calibration point 

was from the theoretical calibration line. To mai.-itain quality control, it was 

assured that these concentration values did not differ from the actual concentrations (i.e., 5, 10, 25, 50, 75, and 100 Ug Cr ) by more than 7 percent 

(to be determined) for five of the six standards. 

EMISSION CALCULATIONS 

All emission calculations were done retaining at least one extra decimal 

figure beyond that of the acquired data. Figures were rounded off after final 

calculations. 

Total Cr in Sample 

The total u9 Cr in each sample, m, was calculated as follows: 

1 0 0 Kc A F Equation C-3 

m = ^——^— — 

va 

Where: 

100 = Volume in ml of total sample. 

A = Absorbance of sample. 

F = Dilution factor (required only if sample dilution was needed to 

reduce the absorbance into the* range of calibration.) 

v = Volume in ml of aliquot analyzed. 

Average Dry Gas Meter Temperature and Average Orifice Pressure Drop 

The average dry gas meter temperature and average orifice pressure drop was 

calculated as described in Method 5.

DETERMINATION OF TOTAL CHROMIUM CONTENT 

"DRAFT METHOD" 

Particulate samples collected using the EPA Method 5 sampling train and 

Method 5 sampling procedures* or particle sizing equipment (see section on 

Determination of Particle Size Distribution) were prepared and analyzed for 

total chromium content using Neutron Activation Analysis (NAA). This was done 

following the procedures in the "EPA Protocol for Emissions Sampling for Both 

Hexavalent and Total Chromium," dated February 22, 1985.** 

SAMPLING APPARATUS 

The sampling train used in these tests were the same as for the Method 5 

tests. No sample-exposed stainless steel or chrome-plated equipment was used 

with the exception of the sample nozzle. In some cases, paper filters were 

used for particulate testing or particle size testing. These trains met design 

specifications established by the U. S. EPA and were assembled by Entropy 

personnel. 

SAMPLING PROCEDURES 

The sampling procedures were performed according to Method 5 (or according 

to the particle size determination sampling procedures). All sampling data 

were recorded on the field data sheets. 

SAMPLE RECOVERY PROCEDURES 

Following sample recovery, all samples were kept dry, protected from 

extreme heat, and analyzed within one month of collection.

insoluble). All sample identification numbers, volumes, and weights were 

recorded on the Sample Preparation and Analysis Data Forms. 

Preparation and Analysis for Method 5 Samples 

Initially, the entire sample was analyzed for hexavalent chromium by the 

EPA Cr Method described in the previous section. The sample residue 

(particulate filter, filtration filter and insoluble materials) for each run 

was then transferred to a separate cleaned and marked sample vial. For samples 

with 2 to 10 grams of material, multiple 5 ml vials (least possible number) 

were used. For samples with greater than 10 grains of material, a portion of 

the filter catch (approximately 4-5 grams) were taken, weighed to the nearest 

0.1 mg, and transferred to a sample vial. For one sample run at each emission 

test location, a 2.0 ml aliquot of the filtrate from the hexavalent chromium 

analysis was transferred to a cleaned and marked vial. 

T he sample blank consisted of the blank residue, including the acetone 

blank (the volume of the acetone blank being approximately equal to the average 

of the acetone rinse volume); a blank particulate filter; and a solution 

filtration filter that had been prepared in the same manner as the field 

samples. This was transferred to a separate cleaned/marked sample vial. 

A ll samples were analyzed for total chromium in terms of Ug of total 

chromium per sample vial. 

Preparation and Analysis for Liquid Process Samples 

Initially, a representative portion of the liquid process sample was 

+6 analyzed for hexavalent chromium by the EPA Cr method. For total chromium 

analysis, a separate representative sample (2.0 ml aliquot) that contained 

greater than 1 ug/-*-*-1*

 o f total chromium was transferred to a sample vial for 

analysis. When the liquid sample was below 1 ug/ml concentration, a 

C-17 
P.68 

For sludge process samples, the entire sample was thoroughly mixed and then 

a representative portion was taken. 

Procedures to Reduce NAA Time 

For all samples that were placed in sample vials, an estimate of the mass 

of chromium was included on the sample log to provide the NAA facility with the 

information necessary to select the proper sample irradiation time and 

strength. When possible, all samples were added to the sample vials in amounts 

that ensured the mas3 of chromium per sample was between 10 Ug and 5,000 Ug. 

When the total chromium value was not known, samples were prepared so that each 

sample vial contained between 5 ug and 100 ug of hexavalent chromium. These 

procedures were followed to allow all known value samples to be irradiated at 

the same time and strength. 

When the sample concentration was unknown or possibly could have exceeded 

5,000 ug of total chromium, such was noted on the sample log sheet. A 

preliminary run on the material was then made to estimate the sample 

concentration. 

When liquid process sample or the 2.0 ral aliquot of the filtrate from the 

hexavalent analysis were below the 10 ug of total chromium value, total mass of 

chromium was recorded on the data sheet to allow these samples to be irradiated 

separately for a longer time and to allow for the selection of a lower 

concentration standard. 

Quality Assurance Sample Analysis 

With every set of 15 samples submitted for NAA, one audit sample was 

submitted to check the analytical technique. 

SAMPLE ANALYSIS 

Sample analysis for total chromium content was done using Neutron 

Activation Analysis (NAA) and was conducted by the Department of Nuclear

Note: In some cases, the mass of Cr was calculated separately, for the 

filter/rinse sample and impinger contents sample, or the masses of both samples 

and both blanks were added to obtain the total concentration. 

Calculation of Chromium in Solid Process Samples 

The chromium concentration in solid process samples, CQ (ug/9)» was 

calculated as follows: 

C = (m - itO/wt Equation C-6

o Comments 

Data concerning barometric pressure, stack gas temperature, and stack gas 

moisture for each run were taken from Method 5 runs performed at the same 

sampling locations on the same days. 

Sample Train Calibration 

Prior to sampling, an in-stack orifice calibration was performed. This 

type of calibration uses a calibrated dry gas meter placed in the line between 

the orifice meter and the blower. The volume of gas passing through the 

orifice meter is measured at a particular pressure drop (AH) across the orifice 

and a corresponding vacuum at a certain temperature and pressure. This 

inforraation is then used to calculate the orifice meter calibration factor 

(Km) for a representative set of AH's. The AH and orifice meter calibration 

factor (K_) during sampling can then later be used to calculate the flow rate 

and volume of gas passing through the train. The calibration data sheet can be 

found in Appendix E. 

SAMPLE RECOVERY PROCEDURES 

The sampling train was carefully moved from the test site to the cleanup 

area. Sample fractions were recovered as follows: 

Container No. 1 - The thimble filter was removed from its holder and 

placed in a glass jar. Loose particulate and acetone washings from all 

sample-exposed surfaces prior to the filter were added to the filter in 

the glass jar. The jar was sealed, labeled, and the liquid level was 

marked.
