          "Based on information developed by Radian Corporation during
Phase I and II studies, the Industrial  Studies Branch recommends not to
develop new source performance standards for the potash industry.  The
Standards Development Branch concurs with this recommendation."

              Testing  to  determine  participate emissions  from  a  potash  plant  was
    conducted  by Scott Environmental  Technology,  Inc.  for the  U.  S.  Environmental
    Protection Agency  under  Contract  No.  68-02-2813, Work Assignment No.  31.   The
    testing was conducted on April  18 and 19, 1979  at  the Kerr-McGee Chemical
    Corporation plant  located in  Trona,  California.
              Total  particulates  were measured at the  inlet  and  outlet  of
    control equipment  serving a potassium chloride  drier.  The control  equipment
    consists of two  cyclones in parallel  followed by a venturi scrubber.   Total
    particulates were  also measured at the outlet of a baghouse  controlling
    emissions  from a potassium sulfate drier.  Total particulates were  determined
    by EPA Method #5.   The mass flow  rate of particulate  at  the  baghouse  inlet
    was estimated during  the testing  by  weighing  the particulate collected by the
    baghouse.   The particle  size  distribution was determined at  the  cyclone  inlet
    and scrubber outlet of the potassium chloride drier and  the  baghouse  outlet
    of the potassium sulfate drier  using an Andersen cascade impactor.  Samples
    of the baghouse  catch were analyzed  for particle size by Bahco analysis.
    Opacity of the gas emitted to the atmosphere  from  the scrubber and  from
    the baghouse was monitored during each test by  a smoke reader.
              The test arrangements were made through  Mr.  Leonard Harris  and
    Mr. Stan Clift of  Kerr-McGee.  Mr. Dennis Holzschuh of the EPA was  present
    during the tests,  as  was Mr.  Pat  Murin of Radian Corporation, who monitored
    the plant  processes.

                        2.0 SUMMARY OF RESULTS
          Results of the total  participate tests conducted on the cyclone
inlet and scrubber outlet of the potassium chloride drier are shown below
in Table 2.1.  Only two tests were completed at the scrubber outlet, and
Test No. 3 at the cyclone inlet was shortened because the plant personnel
reduced the pressure drop across the scrubber on April  19, 1979.   The
high pressure drop was causing excessive leakage in the duct leading to the
scrubber.

          Complete participate results are presented in Appendix A.  Field
data sheets are included in Appendix B.
          Results of the three particle size analyses at the cyclone inlet of
the potassium chloride drier are shown in tabular form in Tables 2.3 through
2.7, and graphically in Figures 2.1, 2.2 and 2.3.  The particle size test run
at the scrubber outlet was run after the pressure drop across the scrubber
had been reduced and therefore, the results may not be representative of the
particle size with the high pressure drop.  Field data sheets are included in
Appendix B.
          Results of the Bahco particle size analysis of the three samples of
the baghouse catch collected during the total particulate tests are summarized
in Tables 2.8 through 2.10, and Figure 2.4.  Complete results are included in
Appendix C.
          Results of the opacity readings taken at the scrubber outlet and
baghouse outlet are summarized in Tables 2.11 through 2.15.   The overall
average opacity at the scrubber outlet was 20% for Test No.  1 and 5% for
Test No. 2.  These readings were complicated by the presence of a steam plume
and shifting winds.  An improved observation point was found for Test No. 2.
The overall average opacity at the baghouse outlet was 5, 5  and 9% for Tests
No. 1, No. 2 and No. 3 respectively.  Opacity observation sheets are included
in Appendix D.

                        3.0  PROCESS DESCRIPTION
          The two processes tested involve the production of potassium
chloride and potassium sulfate.   Potassium chloride is dried in a rotary
gas-fired drier as the final  step of production before being sent to storage
for packaging.  Exhaust gases from the drier pass through two cyclones in
parallel and a venturi scrubber  with a moisture dropout chamber before being
released to the atmosphere.  Testing of the exhaust gases was conducted
before the cyclones and after the scrubber.  Figure 3.1 shows the relative
location of the plant equipment  and the sampling locations.
          Potassium sulfate is also dried in a rotary gas-fired drier.  The
exhaust gases from this drier pass through a baghouse before venting to the
atmosphere.  Sampling of the gases was conducted at the baghouse outlet.
Figure 3.2 shows the arrangement of equipment.

                4.0 SAMPLING AND ANALYTICAL PROCEDURES
          Gas sampling for total participate content was conducted at the
cyclone inlet, scrubber outlet, and baghouse outlet in accordance with EPA
Reference Method #5.  This method involves the isokinetic extraction of a
sample from the gas stream and collection of the particulate on a heated
out-of-stack filter.  A dry gas meter measures the volume of the gas sample.
The gas velocity in the duct is measured during the sampling with a Pi tot
tube and inclined manometer.  The stack gas temperature is measured with a
chromel-alumel thermocouple.  The quantity of particulate collected is
determined gravimetrically with results reported as grains of particulate
per standard cubic foot of gas and grams per cubic meter.
          The mass flow rate of particulate at the baghouse inlet was estimated
by weighing the particulate dropped out of the baghouse in a container.  Since
a considerable quantity of particulate was retained by the fan suction in the
baghouse, the fan was shut down to empty the baghouse before the particulate
was collected at the end of the sampling period.
          The samples for particle size distribution at the cyclone inlet,
scrubber outlet and baghouse outlet were collected using an Andersen 2000
in-stack cascade impactor.  The particules are collected by impaction on a
series of plates.  The plates have increasingly smaller holes so that the
velocity of the particles is increased from plate to plate and smaller and
smaller particles are impacted.  The particulate weight collected on each
plate is determine gravimetrically.  The particle size distribution is based
on the equivalent aerodynamic size of the particles based on spherical
particles of 1 gram/cc density.  A cyclone preseparator was used on the
Andersen sampler at the cyclone inlet due to the large amount of particulate.
          The particle size distribution at the baghouse inlet was determined
by Bahco analysis of particulate samples of the baghouse catch in accordance
with ASME Power Test Code #28.  The Bahco procedure separates the particles
into nine size fractions based on terminal settling velocity.  The particles
are separated by subjecting them to centrifugal force on a spinning plate
with a progressively larger opposing air current.  The analysis was performed
by Western Precipitation Division, Joy Manufacturing Company.
          Opacity readings of the scrubber outlet and baghouse outlet gases
were made in accordance with EPA Method #9 by a certified smoke reader.
