                               INTRODUCTION
          Under the Glean Air Act of 1970,  the Environmental  Protection
Agency (EPA) is charged with establishment  of standards  of performance
for new stationary sources in industry categories which  may contribute
significantly to air pollution.

          A performance standard is based on the best  emission reduction
systems which have been shown to be technically and economically feasible.

          In order to set realistic performance standards, accurate  data
on pollutant emissions is normally gathered from the stationary source
category under consideration.

          The gypsum plant of the Flintkote Company at Blue Diamond,  Nevada,
is equipped with a system for particulate emission reduction  and was  selected
for testing as part of the nonmetallic minerals industry study.

          The testing was performed by Midwest Research  Institute (MRI) dur-
ing the period of October 25 to October 29, 1976, at the Flintkote Company
Plant, Blue Diamond, Nevada. The plant manufactures gypsum boards. The gyp-
sum is mined from a nearby gypsum mine, milled, calcined, and recombined
with water to form gypsum boards. Natural gas, No. 2 fuel oil and/or elec-
tricity are used to energize the process. The milling process is the process
of interest. Part of the output flow from each of the five mills is  vented
to the atmosphere through a baghouse. Figure 1 is a schematic illustration
of the gas flow around a typical mill.

          Samples were drawn from two locations:  inlet  and outlet of the
baghouse of Mill No. 2.

          In summary, MRI tests conducted for this project consisted of:

          1.  Three mass particulate (Method 17) runs at the  outlet  of
the baghouse.

          2.  One mass particulate (Method 17 preceded by alundum thimble)
run at the inlet to the baghouse.

          3.  Opacity reading  (Method 9) of the baghouse outlet emission
for the duration of each particulate test.

          4.  Opacity reading  (Method 9) around the mill area, inside
the plant.

          No parallel test for particulate was conducted by  the  plant  per-
sonnel during the testing period.

          Section II of this report is a summary and discussion  of results.
Section III presents the location of sampling points* Section IV presents
the sampling and analytical procedures. The appendices comprise  raw field
data, as well as results of the analysis.
                II.  SUMMARY AND DISCUSSION OF RESULTS
          Several process problems occurred during the testing periods.
These problems forced the cancellation of two tests and the delay and in-
terruption of other tests. Table 1 lists these process problems and the
action taken to alleviate problems during the tests.

          Appendix A contains the analytical data for the particulate sam-
ples. The field log is contained in Appendix B.
A.  Particulate Tests

          Four particulate runs were accomplished:  three outlet runs and
one inlet run. Tables 2 and 3 present a summary of the results for these
runs in metric and English units, respectively. The filterable particulate
data include the catches on the nozzle and filter. The total particulate
data include the filterable particulate, probe and impinger catches (see
Table A-l, Appendix A)«

          Due to the heavy concentration of particulate in the inlet duct,
the probe nozzle was plugged several times during the inlet run. Therefore,
the data from this run are biased toward small particles. The inlet run was
not conducted simultaneously with any of the outlet runs.  Also note that
the flow rate determined at the inlet was less than the outlet average.

          A computer printout of the particulate sampling parameters and
loading is contained in Appendix C. Appendix D contains sample calculations
of particulate emissions. The particulate field data are contained in Ap-
pendix E.

B»  Particulate Sizing

          Dry particulate catches of each of the inlet and outlet  runs were
sized by Battelle Columbus Laboratories. Coulter Counter technique was used
to size the particulate* The aperture size was 140 \im and the sample materials
were dispersed in isopropyl alcohol with 4% Ntfy CNS as the electrolyte.

          The results of the particle size analyses of the inlet and outlet
samples are plotted in Figures 2 and 3, respectively. Appendix F contains
Battelle's write up of these results.
C.  Visible Emissions Measurements

          Opacity readings were recorded from the discharge point of the
tested No. 2 mill for the duration of the particulate tests. Also, visible
emissions observations were conducted around the Mill No. 2 area inside
the plant with each observation point manned by one observer.

          Table 4 presents a summary of the visible emission results taken
from the discharge point of Mill No. 2 baghouse. Opacity readings taken in-
side the plant around Mill No. 2 area are summarized in Table 5. The aver-
age percent opacity was below 7% for the baghouse discharge. The average
percent opacity for the mill area was 0.

          Appendix G contains the field data sheets of the observer loca-
tions and readings.

                     III.  LOCATION OF SAMPLING POINTS
          There were two sampling locations:   the inlet  and outlet  of  the
baghouse (Figure !)•
A*  Inlet to the Baghouse

          A schematic illustration of the sampling location at this inlet
is shown in Figure 4. Two sampling ports, fabricated by MRI and installed
by the plant, are located at a distance of 39 in. (3 duct diameters) down-
stream and more than 26 in. (< 2 duct diameters) upstream from any flow
disturbance in the duct. These two ports are 90 degrees apart and located
in a plane perpendicular to the flow.

          Table 6 gives information on the location of the particulate tra-
verse points. The number of traverse points was determined according to
Method 1 of the Federal Register.
B.  Outlet of the Baghouse

          Figure 5 is a schematic illustration of the outlet duct. The dis-
tance between the roof and the outlet of this duct was too short to comply
with the minimum requirements of Method 1 of the Federal Register. There-
fore, MRI fabricated and installed an extension to this duct (Figures 1
and 5). Two sampling ports are located in the extension part of the duct
and at a distance of more than 8 diameters downstream and 2 diameters up-
stream from any flow disturbance. These two ports were 90 degrees apart
and located in a plane perpendicular to the flow.

          The location of the particulate traverse point and their distances
are given in Table 7. The number of traverse points was determined according
to Method 1 of the Federal Register.

                  IV.  SAMPLING AND ANALYTICAL  PROCEDURES
          Methods 1 through 4 of the Federal Register (Vol.  36, No.  247,
December 23, 1971) and Method 17 of the Federal Register (Vol.  41, No.  187,
September 24, 1976) were followed in the sampling and analysis  of particu-
late runs from the inlet and outlet duct. However,  a alundum thimble was
inserted in front of the filter of Method 17 train for the inlet sampling
run. The back half of each train was analyzed according to Method 5  of  the
Federal Register (Vol. 36, No. 159, August 17, 1971). A schematic illustra-
tion of the train used is given in Figure 6.

          Preliminary velocity and moisture contents of the  flue gas were
determined, according to Methods 2 and 4 of the Federal Register, before
the actual test was started. The data from the preliminary run  were  used
to set the sampling equipment for isokinetic sampling.

          Eight traverse points were used to sample from the outlet  duct.
The sampling time at this outlet was 11 min per traverse point  for  a total
of 88 min. The inlet duct was divided into 28 traverse points.  The  sampling
time at this duct was 3 min per traverse point for a total of 84 min.

          Gas sampling for flue gas compositions was done from  the  partic-
ulate ports. Method 3 of the Federal Register was followed in sampling  and
analyzing for CO, C02, 02, and N2»
