                             SUMMARY
The Emission Measurement Branch of the U.S. Environmental Pro-
tection Agency contracted Roy F. Weston, Inc. (WESTON)  to con-
duct a source testing and analysis program at United States
Gypsum Company's Shoals, Indiana plant.

The program was designed to quantify selected process emissions
and to determine collector performance.  The locations tested,
plus the number and types of tests performed at each site, are
indicated below:

See Appendix C, Sample Calculations, for estimate workup.  Note
that the board end sawing baghouse inlet duct was not sampled
due to the presence of large particulate (up to 6" long by 1/2"
wide)  which could not be collected representatively using a
standard Method 5 train.

                PROCESS DESCRIPTION AND OPERATION
PLANT DESCRIPTION

The United States Gypsum, Shoals, Indiana plant produces wall-
board and plaster products from gypsum ore mined about one mile
from the plant.  A simplified flow diagram for the process used
at the Shoals plant is shown in Figure 1.  Ore stockpiled at the
plant is crushed to about minus 5 cm (2 inches) and then dried
to remove surface moisture.  The dry ore is further ground to
about 90 percent minus 100 mesh in a grinding mill.  The ground
crude gypsum, primarily calcium sulfate dihydrate  (CaS04 •
2H20), is heated to around 571K (300°F) to remove  75 percent
of its water of hydration and thus form calcium sulfate hemihy-
drate (CaS04«l/2H20).  This process is known as calcining.
The calcined gypsum or stucco is mixed with starch, water, and
other additives to form a slurry.  The slurry is spread between
two paper sheets and formed into wet wallboard.  The wallboard
is subsequently dried in a multi-deck kiln, trimmed to the cor-
rect size, and shipped to distributors.

PROCESS EQUIPMENT TESTED

The emission tests conducted at the Shoals plant are shown in
Table 1.  A brief description of the major processing equipment
tested at the plant is provided in the following sections.

Rock Dryer

The rock dryer employed at the Shoals plant is a direct-fired,
co-current rotary dryer.  As crushed wet gypsum is passed
through the dryer, surface moisture is evaporated by hot combus-
tion gases.  A schematic diagram of this type of dryer is shown
in Figure 2.

Kettle Calciner

The calciner used at the Shoals plant is a continuous kettle
calciner.  As finely ground gypsum is fed to the kettle, hot
combustion gases are passed through flues inside the kettle to
provide an indirect transfer of heat to the ore.  The heating of
the ore causes the chemical reaction which produces stucco.  A
schematic diagram of the calcining kettle is shown in Figure 3.

Stucco Storage and Transfer

The stucco storage and transfer system tested at the plant em-
ploys an air conveyor to transfer stucco from a conveyor belt to
a 27.2 Mg (30 ton) surge bin and conventional screw conveyors to
transfer the stucco from the bin to the board forming line.

Board Forming Line

The two boardlines tested at the Shoals plant are of average
size and together are capable of producing about 51 million
square meters (550 million square feet) of wallboard per year on
a half-inch basis.  The process operations tested on the board-
lines, which include board end sawing, paper scoring, and pin
mixing, are typical of those used throughout the gypsum indus-
try.

Plaster Mixing and Bagging

The plaster mixing and bagging unit at the Shoals plant is typi-
cal of those used throughout the gypsum industry.

EMISSION CONTROLS

Fabric filter dust collectors are used at the Shoals plant to
control gypsum particulate emissions.  Dust-laden gases exiting
the rock dryer and the kettle calciner are vented to separate
baghouses.  The dryer has four Buell cyclones upstream of the
baghouse.  Emissions from conveyors, bucket elevators, and stor-
age bins are vented to fabric filter dust collectors.  Boardline
emissions from dry mixing, and board end sawing, are also con-
trolled by baghouses.  Paper scoring and pin mixing emissions
from one of the boardlines are controlled by a cyclone only.
Pin mixing on the other boardline is vented to a baghouse. Emis-
sions from the plaster mixing and bagging operation are vented
to a separate baghouse.

Design and operating parameters for the baghouses tested at the
Shoals plant are given in Table 2.  Estimated operating capaci-
ties for the process units vented to the stucco storage and
transfer baghouse are given in Table 3.

Normal replacement frequencies and most recent replacement dates
for bags in the dust collectors tested are shown in Table 4.

PROCESS CONDITIONS DURING TESTING

In order to ensure that the ore dryer, calciner, boardline, and
plaster operations were operating at representative steady-state
conditions during the testing, various process parameters were
monitored.

All processes operated normally during the emission testing.
The operating condition of each of the processes is discussed in
the following sections.

Continuous Kettle Calciner

During the emission testing of the continuous kettle calciner,
the calciner was operating at full capacity, producing 11.5 tons
of calcined gypsum or stucco per hour.  The average heat usage
of the unit during the testing was 0.85 KJ/g (0.73 million Btu/
ton)  of product.  The unit was burning natural gas.  The stucco
product from the kettle contained combined moisture of 5.7 per-
cent during the testing.  Process data collected during each of
the three EPA Method 5 test runs on the continuous kettle are
shown in Tables 5, 6, and 7, respectively.  The kettle operated
normally during all three test runs.

Rock Dryer

During the emission testing, the rock dryer was operating at 92
percent of design capacity, producing 70 tons of dry rock per
hour.   Process data collected during the EPA Method 5 test runs
is shown in Tables 8, 9, and 10, respectively.   The average heat
usage of the dryer during the testing was 0.08 KJ/g (0.07 mil-
lion Btu/ton)  of dried rock.  The dryer was burning natural
gas.  The free moisture content of the ore entering the dryer
was 1 to 1.5 percent, and the free moisture content of the
exiting rock was less than 0.5 percent.

Some fluctuation in the dryer temperature was observed through-
out the testing of the dryer.  These fluctuations were due to
the fact that the automatic controller on the dryer was out of
service and the fuel firing rate was under manual control.
Changes in the free moisture content of the gypsum feed would
require a different firing rate.  Manual changes in the firing
rate were made whenever the dryer operating temperature varied
significantly from a desired value.   The length of time required
for restabilization of the temperature, which ranged from 10 to
30 minutes, was dependent on the extent of the  deviation from
the desired temperature at the time  the firing  rate was reset.

-------
Estimates of the effect of the temperature fluctuations on the
air flow rate through the dryer show that the maximum variation
in the flow rate during all three test runs should be no greater
than two percent.

The dryer at the Shoals plant has a small heater downstream of
the four small Buell cyclones which are at the outlet of the
dryer.  The emission tests performed on the inlet to the collec-
tor were performed downstream of the heater.  The purpose of the
heater is to heat the process gases entering the baghouse.
Heating these gases reduces the risk that wet particulate matter
will enter the baghouse and blind the filter bags. The burner on
the heater is rated at 440 KJ/sec (1.5 million Btu/hour). The
instrumentation used to measure the natural gas usage of the
rock dryer measured the sum of the main dryer burner and the
heater.  Between the first and second test runs, the heater was
inadvertently left off.  Some difference in the temperature of
the gas stream entering the baghouse may be observed between the
first and second test runs because the temperature set-point on
the heater controller was moved by maintenance and operation
personnel.

Stucco Storage and Transfer

Tne storage and transfer system was operating at normal capacity
during the emission testing.

Board End Sawing

During the board end sawing testing, the No. 2 boardline was
running regular, one half inch board, 12 feet in length.  The
line was operating at a rate of 47.9 meters per minute (157 feet
per minute).

Mixing and Bagging

The plaster mixing and bagging operation was operated by a
single operator during the testing.   Generally, the process is
operated by two operators, one person working the batch mixer
and a second working the bagging machine.  During the testing,
the operator would mix a single batch of plaster, about 1,453
Kg (3,200 pounds), and then return to the bagging machine.  Al-
though operation with a single operator is somewhat abnormal for
this plant, the test data should still be representative since
both emission sources, mixing and bagging, were in continuous
operation.  During most of the testing, the plant was bagging
normal plaster which is about 99-percent stucco; during the re-
mainder of the testing, the plant was bagging a special plaster


                               -23-

-------
containing 13-percent perlite.  The plaster was being put in
50-lb bags at the rate of 500 bags per hour.

Other Process Operations

The remaining processes tested, which include paper scoring and
pin mixing, were tested under normal operating conditions.

                 DESCRIPTION OF  SAMPLING  TRAINS
PARTICULATE SAMPLING TRAINS

The test train utilized for particulate sampling at the Board
End Sawing Baghouse Discharge Stack was the standard EPA Method
5 train (see Figure 9) .

A stainless steel nozzle was attached to a heated (•—250°F)
borosilicate glass probe which was connected directly to a boro-
silicate filter holder containing a 9-cm Reeve Angel 900 AF
glass fiber filter.  The filter holder was maintained at approx-
imately 250 F in a heated chamber, and was connected by
vacuum tubing to the first of four Greenburg-Smith impingers
which were included in the train to condense the moisture in the
gas stream.  Each of the first two impingers contained 100 ml of
distilled water, the third was dry and the final impinger con-
tained 200 grams of dry pre-weighed silica gel.  The first,
third, and fourth impingers were modified Greenburg-Smith types;
the second was a standard Greenburg-Smith impinger.   All
impingers were maintained in a crushed ice bath.  A RAC control
console with vacuum pump, dry gas meter, a calibrated orifice,
and inclined manometers completed the sampling train.

Flue gas temperature was measured by means of a calibrated Type
K thermocouple which was connected to a direct readout pyrom-
eter.  The thermocouple sensor was positioned adjacent to the
sampling nozzle.

Gas velocity was measured using a calibrated S-type pitot tube
provided with extensions and fastened alongside the sampling
probe.  Gas stream composition (carbon dioxide, oxygen, and car-
bon monoxide content)  was determined utilizing Orsat apparatus
to analyze stack gas samples.  Gas stream composition proved to
be ambient air with the exception of the Rock Dryer inlet and
outlet test sites which contained products of combustion.

Figure 10 shows the EPA Method 5 train utilized at the No. 4
Kettle Calciner Baghouse and at the Rock Dryer Baghouse loca-
tions.  The test train shown is identical to the one described
above, except a rigid glass connection is used between the back
half of the filter holder and the first impinger, rather than
the flexible vacuum tubing.

PARTICLE SIZE DISTRIBUTION SAMPLING APPARATUS

A stainless steel nozzle was connected directly to an 8-stage
Andersen cascade impaction device which separated the particles
according to their effective aerodynamic particle diameters.  A
solid glass fiber filter was used to capture any particles that
passed through the impactor substrates to permit the measure-
ment of total particulate.  The filter holder was maintained at
stack temperature and was connected by vacuum tubing to the
first of four Greenburg-Smith impingers which were included in
the train to condense the moisture in the gas stream.  All
impingers were maintained in a crushed ice bath.  A RAC control
console with vacuum pump, dry gas meter, calibrated orifice, and
inclined manometers completed the sampling train (Figure 11).

                         TEST PROCEDURES
PRELIMINARY TESTS

Preliminary test data was obtained at each sampling location-
Stack geometry measurements were recorded and sampling point
distances calculated.  A preliminary velocity traverse was
performed at each test location utilizing a calibrated S-type
pitot tube and a Dwyer inclined manometer to determine velocity
profiles.  A check for the presence or absence of cyclonic flow
was conducted at each test location prior to formal testing.
Stack gas temperatures were observed with a direct readout
pyrometer equipped with a chromel-alumel thermocouple.

Preliminary test data was used for nozzle sizing and nomagraph
set-up for isokinetic sampling procedures.

Calibration of the probe nozzles, pitot tubes, metering systems,
probe heaters, temperature gauges and barometer were performed
as specified in Section 5 of EPA Method 5 test procedures.  See
Appendix D for calibration data.

FORMAL TESTS

No. 4 Kettle Calciner Baghouse Inlet Duct

A series of three tests were conducted at the No. 4 Kettle Cal-
ciner Baghouse Inlet Duct to measure the concentration and mass
rate of particulate matter emissions.  Nine traverse points (3
per port axis) were sampled for 3 minutes each resulting in a
total test time of 27 minutes.  The Technical Manager approved
the reduced sampling interval due to the high grain loading
(—110 gr/DSCF) encountered.

During particulate sampling, gas stream velocities were measured
by inserting a calibrated S-type pitot tube into the stream
adjacent to the sampling nozzle.  The velocity pressure
differential was observed immediately after positioning the noz-
zle at each point, and sampling rates were adjusted to maintain
isokinetic sampling.  Stack gas temperatures were also monitored
at each point with the pyrometer and thermocouple.  Additional
temperature measurements were made at the final impinger and at
the inlet and outlet of the dry gas meter.

Test data were recorded at each traverse point during all test
periods.  Leak checks were performed according to EPA Method 5
                              -39-

instructions prior to and after each run and/or component
change.  Tables 11 and 12 present a summary of test data for
each of the three runs.  Test result summarization appears in
Tables 21 and 22.

Condensation problems precluded the use of the cascade impactor
for particle sizing.  Particle size distribution analyses were
conducted on the combined filter and cyclone particulate
catches.  See Appendix B for results.

No. 4 Kettle Calciner Baghouse Discharge Stack

Three Method 5 tests were performed on the No. 4 Kettle Calciner
Baghouse Discharge Stack.  Eight points were traversed (4 per
port)  for 12 minutes, each yielding a test period of 96 minutes.

Procedures for isokinetic sampling were identical to those
described for the No. 4 Kettle Calciner Baghouse Inlet Duct.

See Tables 13 and 14 for test data and Tables 23 and 24 for
test result summaries, respectively.

Visual determinations of plume opacity were performed by a cer-
tified observer according to Method 9 procedures during all
three test runs.  A summary of results is presented in Table 36.
No particle size distribution tests were conducted at this test
point due to moisture condensation problems.

                                                    *
Three 64 minute Method 5 test runs were performed at the Rock
Dryer Inlet Duct.  A total of 32 points were sampled for two
minutes each per test.

Isokinetic sampling procedures were identical to those previ-
ously described.  Tables 15 and 16 show test data summarization
and Tables 25 and 26 present test results.

One sampling point located at a site of average velocity was
selected from particulate traverse data for particle size dis-
tribution testing.  The gas stream was sampled isokinetically at
that point for 4 minutes for Test Runs 1 and 2f and for 3 min-
utes for Test Run 3.  This permitted collection of sufficient
sample for analysis without overloading the filter substrates.
Sample volume, temperature, and pressure data were recorded.
See Tables 31 through 33 for distribution results.

-------
Rock Dryer Baghouse Discharge Stack

Three Method 5 test runs were conducted on the Rock Dryer Dis-
charge Stack.  Eight sampling points (4 per axis) were sampled
for eight minutes each, yielding a test period of 64 minutes.

Sampling procedures were identical to those previously
described.  See Tables 17 and 18 for test data and Tables 27 and
28 for test result summaries, respectively.

One particle size distribution test was completed at an average
point of velocity.  Total test time was 120 minutes with read-
ings taken every 5 minutes.  See Table 34 for particle size dis-
tribution results.

Visual determinations of plume opacity were performed by a cer-
tified observer according to Method 9 procedures during all
three particulate test runs.  A summary of results is presented
in Table 37.

Board End Sawing Baghouse Discharge Stack

Three 64 minute Method 5 test runs were conducted at the Board
End Sawing Baghouse Discharge Stack.  A total of eight points
(4 per port) were sampled for eight minutes each per test.

Isokinetic sampling procedures were identical to these previ-
ously described.  Tables 19 and 20 show test data summarization
and Tables 29 and 30 present test results.

One particle size distribution test was completed at an average
point of velocity.  Total test time was 120 minutes with
readings taken every 5 minutes.  See Table 35 for particle size
distribution plot.

Three Method 9 plume opacity determinations were performed by a
certified observer during the three particulate test runs.  A
summary of results is presented in Table 38.

Other Test Points

The visible and fugitive emission tests conducted at the remain-
ing test points were 1 hour in duration each.

                      ANALYTICAL PROCEDURES
PARTICIPATE SAMPLE RECOVERY

At the conclusion of each test, the sampling trains were dis-
mantled, openings sealed, and the components transported to the
field laboratory.  Sample integrity was assured by maintaining
chain-of-custody records, which will be supplied upon request.

A consistent procedure was employed for sample recovery.

    Tne glass fiber filter(s) was removed from its holder with
    tweezers and placed in its original container (petri dish),
    along with any loose particulate and filter fragments
    (Sample Type 1) .

    The probe and nozzle were separated, and the internal
    particulate rinsed with acetone into a borosilicate
    container while brushing a minimum of three times until no
    visiole particles remained.  Particulate adhering to the
    brush was rinsed with acetone into the same container.  The
    front half of the filter holder was rinsed with acetone
    while brushing a minimum of three times.  The rinses were
    combined (Sample Type 2)  and the container sealed with a
    Teflon-lined closure.  Fluid levels were marked to deter-
    mine whether or not leakage occurred during transport.  The
    container was labeled to clearly identify its contents.
    The total liquid in impingers one, two and three was
    measured, the value recorded, and the liquid discarded.

    The silica gel was removed from the last impinger and
    immediately weighed.

    An acetone sample was retained for blank analysis.

PARTICULATE ANALYSES

The filters (Sample Type 1)  and any loose fragments were desic-
cated for 24 hours and weighed to the nearest 0.1 milligram to a
constant weight.

The acetone wash samples (Sample Type 2) were evaporated at
ambient temperature and pressure in tared beakers, and desic-
cated to constant weight.  All sample residue weights were
adjusted by the acetone blank value.
                               -43-

-------
The weight of the material collected on the glass fiber fil-
ter (s) plus the weight of the residue of the acetone
nozzle/probe/front-half filter holder washes represents the
total EPA Method 5 catch.  Complete laboratory results are pre-
sented in Appendix B of this report.

PARTICLE SIZE SAMPLE RECOVERY AND ANALYSES

The cascade impactor substrates and any loose fragments were
carefully removed from their support plates with tweezers and
placed in individual containers (petri dishes)  for shipment to
WESTON's laboratory.

Each cascade impactor filter was fired at 525°C and pre-
weighed to the nearest 0.1 milligram to constant weight at
WESTON's laboratory prior to on-site application.  Subsequent to
emissions exposure, the cascade impactor substrates, back-up
filters, and any loose fragments were desiccated for 24 hours
in the laboratory, and weighed to the nearest 0.1 milligram to
constant weight.
                               -44-

-------
                   TEST RESULTS AND DISCUSSION
Particulate test data and test result summaries are presented in
Tables 11 through 30 of this section.  Tables 31 through 35 list
the particle size distribution of the particulate matter for
all locations.  Visible emission test data summaries are shown
in Tables 36 through 41.  See Tables 42 and 43 for fugitive
emission test result summaries.

No unusual process operating problems were encountered during
the test periods.  However, a visible plume of 20 percent
opacity emanating from the Surge Bin Baghouse (indicating leak-
ing bags) prohibited the conduct of Method 9 tests on the source
until repairs were effected.  A WESTON observer returned to the
plant site on 10 June 1980 to perform the visible emission
tests following the completion of collector maintenance.

The following sampling difficulties occurred during the survey:

    1.  No Andersen particle size distribution tests were
        performed at the No. 4 Kettle Calciner Baghouse test
        points.  Gas stream moisture content of ~70 percent
        caused condensation problems on the filter substrates
        precluding the use of this technique.  At the inlet test
        point, the dry filter and cyclone catches were combined
        and the resultant sample submitted for sedigraph
        particle size distribution analysis.  No particle
        sizing was conducted at the outlet test point.

    2.  Test period length for the particulate tests performed
        at No. 4 Kettle Calciner Baghouse Inlet Duct was reduced
        for practical sampling considerations (particulate
        loadings of ~110 grains/DSCF) to 27 minutes as approved
        by the EPA Technical Manager.

The quantity of particulate matter discharged to the atmosphere
from the No. 4 Kettle Calciner Baghouse Discharge Stack was
  s^O.020 grains/DSCF and ^0.093 pounds/hour.  The certified
visible emission observer recorded plume opacities of  ^5 per-
cent for this source.

The particulate matter discharged from the Rock Dryer Discharge
Duct was ^0.005 grains/DSCF and  ^0.341 pounds/hour.  The
opacity readings recorded by the certified observer were ^5
percent.
                               -45-

-------
The particulate matter discharged from the Board End Sawing Bag-
house Discharge Duct was < 0.010 grains/DSCF and <0.307
pounds/hour.  The opacity readings recorded by the certified
observer were  < 5 percent.

The particulate removal efficiency of the No. 4 Kettle Calciner
Baghouse averaged 99.99 percent for the three tests; the effi-
ciency of the Rock Dryer Dust Collector averaged 99.87 percent;
the efficiency of the Board End Sawing Baghouse averaged 99.91
percent.

Note that the collection efficiency of the Board End Sawing Bag-
house was calculated based on an estimate of uncontrolled emis-
sions (see Appendix C for estimate workup).  The inlet duct was
not sampled due to the presence of large particulate (up to 6"
long by 1/2" wide)  which could not be collected representatively
using a standard Method 5 train.
