                            1.0  INTRODUCTION




          Source sampling tests were performed at the Keystone, West




Virginia plant of Eastern Associated Coal Company on February  23 and




24,  1972.  The company operates a coal preparation operation at this




site.  In order to control the emissions to the atmosphere  from this




operation, the exhaust gases pass through a Fangborn Baghouse  collector




before entering the atmosphere.




          It was the purpose of the test program to determine  the




quantity of particulate matter being emitted to the atmosphere from the




collector.  Triplicate tests were performed, running one  test  the  first




day and two tests the next day.  Figure 1 shows the location of the




sampling points.

          A summary of test results is presented in Table  1.  Table  2




presents a summary of the particulate weights.  All of the particulate




results are included in Appendix A and the raw data sheets are  included




as Appendix B.




          In observing Table 2 it is seen that there is no weight  included




for Container 5 during Run 1.  This was due to the fact that  it was




discovered that the hydrocarbon stopcock grease used was attacked  by




acetone.  An acceptable type of stopcock grease was obtained  and used




for the remaining two runs.

                  3.0  PROCESS DESCRIPTION AND OPERATION




          The Keystone Preparation Plant of Eastern Associated Coal




 cleans No. 3 Pocahantas coal for metallurgical use by both wet and dry




 methods.  Minus 3/8 in. coal is processed through air tables with the




 middlings recombined with plus 3/8 in. raw coal for wet processing.




 Six  R & S Super Airflo tables are used at approximately 30,000 cfm air




 flow, 40  tons/hr. coal being cleaned per table.




          Six Pangborn baghouses clean exhaust air, using 110 bags per




 baghouse.  Dynel  bags are currently used in five baghouses.  Cotton bags




 were formerly used, but are gradually being phased out.  The unit




 tested had dynel  bags.  The bags are cleaned by shakers activated by




 manual control at 2-3 hour intervals.  There was no manual shaking of




 the  bags  during any of the test runs.




          The only process variables monitored were the coal moisture




content to the tables and the table feeder arm speed.   The former was




measured with a probe developed by Consolidation Coal Company which




operates on a flow resistance principle.   Assuming the charts were




calibrated properly, the moisture content of raw coal feed varied




from 3.2 percent to 6.5 percent during the tests.  Table feed had been




set so that the six tables were fed coal at identical rates.




          Loadout of cleaned coal was effected at the same rate as




production during the tests.   This indicated a cleaned coal rate of




38 tons/hr.  per table.

                     4.0  LOCATION OF SAMPLING POINTS




          From the baghouse collector the exhaust gases were emitted to




the atmosphere through a 42 in. by 42 in. stack.  The sample ports were




all located on one side of the stack as shown in Figure 1.  There were




three ports which were located at the distances shown in Figures 1 and 2,




These ports were located approximately 6 feet downstream from a fan and




approximately 6 to 12 inches upstream from the outlet of the stack (the




tope of the stack being inclined rather than flat).




          Figure 2 shows the exact location of each sample point in the




cross section.  Six points were sampled in each port giving a total of




eighteen points for the test.  The three ports were labeled A, B, and C




starting at the east side of the stack and moving to the right.  The




traverse points were numbered from 1 to 6 starting with 1 being nearest




to the port.  The distance from the port to the first point was 3*5 in.




while the distances between the remaining points were each 7 in.




          The testing was conducted from the roof of the building.




There was no requirement for any special scaffolding or platforms.

                 5.0  SAMPLING AND ANALYTICAL PROCEDURES




          The sampling procedure used was the same as that specified by




Method 5 - "Determination of Particulate Emissions From Stationary




Sources" and published in the Federal Register, Volume 36, No. 247,




Thursday, December, 1971.  This method is attached as Appendix E.  In




addition, the impinger catch was analyzed.




          Briefly, the method consists of withdrawing a sample iso-




kinetically from the stack through a heated glass probe into  a filter




and impinger train.  The sample volume is measured with a dry gas meter




and isokinetic conditions maintained by monitoring the stack  gas velocity




with an "S" type pitot tube.




          After testing, the train was thoroughly washed including the




probe.  The washings were evaporated, dried and weighed along with the




filter in order to come up with a total weight of particulate matter




collected.




          The stack gas velocity and flow rate was measured using




Method 2 - "Determination of Stack Gas Velocity and Volumetric Flow




Rate (Type S Pitot Tube)", and published in the Federal Register.




Using both the weight of sample collected and the flow rate determined,




a total particulate emission rate was calculated.

 method (s)  prescribed by the manufac-
 turer(s) of such instrument, the instru-
 ment shall be subject to manufacturers
 recommended zero adjustment calibra-
 tion procedures at least once per 24-hour
 operating  period unless the  manufac-
 turer (s) specified or recommends cali-
 bration  at shorter intervals, in  which
 case such specifications or recommenda-
 tions shall be followed.  The  applicable
 method specified in the appendix of this
 part shall be the reference method.
   (c) Production rate and hours of op-
 eration shall be recorded daily.
   (d) The owner or operator of any sul-
 furlc acid production unit subject to the
 provisions  of this subpart shall maintain
 a  file of all measurements required by
 this subpart. Appropriate measurements
 shall be reduced to the units of the ap-
 plicable standard daily and summarized
 monthly. The record of any such  meas-
 urement and summary shall be retained
 for at least 2 years following the date
 of such measurements and summaries.
 § 60.85  Test methods and procedures.
   (a) The provisions of this section are
 applicable to performance tests for deter-
 mining emissions of acid mist and sulfur
 dioxide from sulfuric acid  production
 units.
   (b) All performance tests shall be con-
 ducted while the affected facility is oper-
 ating at or above  the  maximum acid
 production  rate  at which  such facility
 will  be  operated and under such other
 relevant conditions as the Administrator
 shall specify based on representative per-
formance of the affected facility.
   (c) Test methods set forth in the ap-
 pendix to this part or equivalent methods
 as approved by the .Administrator shall
 be used as follows:
   (1) For  each repetition the acid mist
and  SO, concentrations shall be deter-
mined by using Method 8 and traversing
according  to  Method 1.  The  minimum
sampling time shall be 2 hours, and mini-
mum sampling  volume shall  be 40 ft.'
corrected to standard conditions.
   (2) The volumetric flow rate  of  the
total effluent shall be determined by using
Method  2  and  traversing  according to
Method 1.  Gas  analysis  shall be per-
formed by  using the Integrated sample
technique of Method 3. Moisture content
can be considered to be zero.
   (d) Acid produced, expressed in tons
per  hour of  100 percent sulfuric acid
shall be determined during each 2-hour
testing period by suitable flow meters and
shall be confirmed by a material balance
over the production system.
   (e) For each repetition acid mist and
sulfur dioxide emissions, expressed  in lb./
ton of 100 percent sulfuric acid shall be
determined by dividing the emission rate
in lb:/hr.  by the  acid produced. The
emission  rate shall  be determined  by
the   equation,   lb./hr.<=QsXc,    where
Qa=volumetric flow rate of the effluent
in ft.'/hr. at standard conditions, dry
basis as determined in accordance with
paragraph  (c) (2)  of this section, and
c=acid mist and SO, concentrations in
lb./ft.8 as determined in accordance with
paragraph  (c)(l)  of this  section, cor-
rected to standard conditions, dry  basis.
        APPENDIX—TEST METHODS
METHOD  1—SAMPLE AND VELOCITY TRAVERSES
         FOR STATIONARY SOURCES
  1. Principle and Applicability.
  1.1  Principle. A sampling site and the
number  of traverse points are selected to aid
in the extraction of a representative sample.
  1.2  Applicability.  This  method   should
be applied only when specified by the test
procedures for determining compliance with
the New Source Performance Standards. Un-
less otherwise specified, this method  Is not
Intended to apply  to gas streams other than
those emitted directly  to the atmosphere
without  further processing.
  2. Procedure.
  2.1  Selection of a sampling site and mini-
mum number of traverse points.
  2.1.1  Select a sampling site that Is at least
eight stack or duct diameters  downstream
and two diameters upstream from any flow
disturbance such as a bend, expansion, con-
traction,  or  visible flame. For rectangular
cross section, determine an equivalent diam-
eter from the following equation:
                      2.1.2  When  the  above  sampling  site
                    criteria can be  met, the minimum number
                    of traverse points Is twelve (12).
                      2.1.3  Some sampling situations render the
                    above  sampling site  criteria  Impractical.
                    When this Is  the case, choose a convenient
                    sampling location and use Figure 1-1 to de-
                    termine the minimum  number of traverse
                    points. Under no conditions should a sam-
                    pling point be selected within 1 Inch of the
                    stack wall. To obtain the number of traverse
                    points for stacks or ducts with a diameter
                    less  than 2  feet, multiply the number of
                    points obtained from Figure 1-1 by 0.67.
                      2.1.4  To use  Figure 1-1 first measure the
                    distance from the chosen sampling location
to the nearest upstream and downstream dis-
turbances.  Determine  the  corresponding
number of traverse points for each distance
from Figure 1-1.  Select  the higher of the
two numbers of traverse points, or a greater
value, such that for circular stacks the num-
ber Is a multiple  of 4, and for rectangular
stacks  the  number follows the criteria of
section 2.2.2.
  2.2  Cross-sectional layout and location of
traverse points.
  2.2.1   For circular stacks locate  the  tra-
verse points on at least  two  diameters ac-
cording to Figure 1-2 and Table 1-1.  The
traverse axes shall divide the stack cross
section Into equal  parts.

METHOD  2	DETERMINATION  OF  STACK  OAS
  VELOCITY AND VOLUMETRIC PLOW BATE (TYPE
  S PTTOT TUBE)

  1. Principle and applicability.

  1.1  Principle. Stack gas velocity is deter-
mined from the gas density and from meas-
urement of the velocity head using a Type S
(Stauschelbe or reverse type) pltot tube.
  1.2  Applicability. This method should be
applied only when  specified by the test  pro-
cedures for determining compliance with the
New Source Performance Standards.
  2. Apparatus.
  2.1 Pttot tube—Type 8  (Figure 2-1), or
equivalent,  with a coefficient  within ±5%
over the working range.
  2.2 Differential pressure gauge—Inclined
manometer, or equivalent, to measure velo-
city head to within  10%  of  the minimum
value.
  2.3 Temperature gauge—Thermocouple or
equivalent  attached  to the pltot tube to
measure stack temperature to within 1.6% of
the  minimum  absolute stack temperature.
  2.4 Pressure gauge—Mercury-filled U-tube
manometer, or equivalent, to measure stack
pressure to within 0.1 in. Hg.
  2.5 Barometer—To measure atmospheric
pressure to within 0.1 In. Hg.
  2.6 Gas analyzer—To analyze gas composi-
tion for determining molecular weight.
  2.7 Pilot  tube—Standard  type, to cali-
brate Type S pltot tube.
  3. Procedure.
  3.1 Set up the apparatus as  shown In Fig-
ure 2-1. Make sure all connections are tight
and leak free. Measure the velocity head and
temperature at the traverse points specified
by Method L
  3.2 Measure  the static  pressure  In  the
stack.
  3.3 Determine  the stack gas molecular
weight  by gas analysis and appropriate  cal-
culations as Indicated In Method 3.
  4.  Calibration.

  4.1 To calibrate the pltot tube, measure
the velocity head at some point In a flowing
gas stream with both a Type 8 pltot tube and
a standard type pltot tube with known co-
efficient. Calibration should  be done In the
laboratory and the velocity of the flowing gas
stream  should be  varied  over the normal
working range. It Is recommended that the
calibration be repeated after use at each field
site.
  4.2 Calculate  the pltot tube  coefficient
using equation 2-1.
                              equation 2-1
where:
  c"telt — Pltot  tube coefficient  of  Type  S
            pltot tube.
   Cp,,a=Pltot  tube coefficient of standard
            type pltot tube (If unknown, use
            0.99).
   Ap.tdzr Velocity head measured by stand-
            ard  type pltot tube.
  Apt..t = Velocity head measured by Type S
            pltot tube.
  4.3 Compare the coefficients of the Type S
pitot tube determined first with  one leg and
then the other pointed downstream. Use the
pltot tube only If the two coefficients differ by
no more than 0.01.
  5.  Calculations.   ~
  Use equation 2-2 to calculate the stack gas
velocity.

 METHOD  6—DETERMINATION  or PABTTCULATE
    EMISSIONS FROM STATIONARY SOURCES

   1. Principle and applicability.
   1.1   Principle. Partlculate matter is with-
 drawn  Isokinetioally from  the source and its
 weight is determined gravimetrically after re-
 moval  of uncomtolned water.
   1.2   Applicability. This method Is applica-
 ble for the determination of partlculate emis-
 sions  from  stationary  sources  only when
 specified by the test procedures for determin-
 ing compliance  with  New Source  Perform-
 ance Standards.
   2. Apparatus.
   2.1   Sampling train. The design specifica-
 tions of the partlculate sampling train used
 by EPA (Figure 6-1)  are described In APTD-
 0581. Commercial  models  of this train are
 available.
   2.1.1 Nozzle—Stainless  steel  (316)  with
 sharp,  tapered  leading edge.
   2.1.2 Probe—Pyrex1 glass with a heating
 system capable of maintaining a minimum
 gas temperature of 250' F.  at  the exit end
 during sampling  to  prevent condensation
 from  occurring.  When length limitations
 (greater than about 8 ft.)  are encountered at
 temperatures less than 600* F., Incoloy 825 ',

               4. Procedure.
               4.1  Sampling
               4.1.1  After selecting the sampling site and
             the minimum number of sampling .points,
             determine the. stack pressure, temperature,
             moisture, and range  of velocity head.
               4.1.2  Preparation   of   collection  train.
             Weigh to the nearest gram approximately 200
             g. of silica gel. Label  a filter  of proper diam-
             eter, desiccate'  for at least 24 hours  and
             weigh to the nearest 0.5 mg. In a room where
             the relative humidity is less than 50%. Place
             100 ml. of water in each of  the  first  two
             Implngers, leave the third impinger empty,
             and place approximately 200 g.  of preweighed
             silica  gel in the fourth Impinger. Set up the
             train  without the probe as in Figure  5-1.
             Leak check the sampling train at  the sam-
             pling site by plugging up the Inlet to the fil-
             ter holder and pulling a 15 In. Hg vacuum. A
             leakage rate not in excess of 0.02 c.f.m.  at a
             vacuum of 15 in. Hg is acceptable. Attach
             the probe and adjust the heater to  provide a
             gas temperature oT about 250° F. at the probe
             outlet. Turn  on the  filter heating system.
             Place  crushed Ice around the Implngers.  Add

                                            more ice during the run to keep the temper-
                                            ature of the gases leaving the last Impinger
                                            as low as  possible and preferably at 70° F..
                                            or less. Temperatures above 70° F. may result
                                            in damage to the dry gas meter from either
                                            moisture condensation or excessive heat.
                                              4.1.3  Partlculate train operation. For each
                                            run, record the data required on the example
                                            sheet shown In Figure 5-2. Take readings at
                                            each sampling point, at least every 5 minutes,
                                            and when significant  changes in stack con-
                                            ditions  necessitate additional  adjustments
                                            in flow rate. To begin .sampling, position the
                                            nozzle at  the first traverse point with the
                                            tip pointing directly into the  gas  stream.
                                            Immediately start the pump and adjust the
                                            now to  isokiiietic  conditions. Sample for at
                                            least 5 minutes at each  traverse  point; sam-
                                            pling time must be the  same for each point.
                                            Maintain isolUnetlc sampling throughout the
                                            sampling  period. Nomographs are available
                                            which aid In  the rapid adjustment of the
                                            sampling  rate without  other computations.
                                            APTD-0576 details the  procedure  for using
                                            thesa nomographs. Turn off the pump at the
                                            conclusion of each run  and  record the final
                                            readings. Remove the probe  and nozzle from
                                            the stack and handle  in accordance with the
                                            sample recovery process described in section
                                            4.2.

METHOD 6	DETERMINATION OP SULFUR DIOXIDE
    EMISSIONS FROM STATIONARY SOURCES

   1. Principle and  applicability.
   1.1  Principle. A gas sample is extracted
from the sampling point In  the stack. The
acid mist, including  sulfur trtoxlde, is sepa-
rated from the sulfur dioxide.  The  sulfur
dioxide fraction Is  measured by the barium-
thorin titration method.
   1.2 Applicability.  This  method  Is  appli-
cable for the determination of sulfur dioxide
emissions from stationary sources only when
specified by the  test procedures for determin-
ing compliance with New Source Performance
Standards.

                       STANDARD SAMPLING PROCEDURES




           The sampling procedures used during the test are  the  same




 as those published in the Federal Register, Volume 36, Number 24,




 Thursday, December 23, 1971.  These methods are as follows  (Methods




 1, 2,  5).  Additionally,  the impinger catch was analyzed for




 particulate content.

                            LABORATORY REPORT




1.  On Site Handling and Transfer




          After the completion of a test run, the probe and nozzle were




disconnected from the impinger train and all open ends sealed immediately




to avoid any possible contamination.  At the laboratory facility, the




nozzle was disconnected from the probe and very carefully washed with




acetone, using a fine bristled brush.  All acetone washings were collected




in a clean glass jar, the jar itself being placed on a large piece of




clean aluminum foil.  The probe was then washed with acetone, using a




long-handled brush.  The brush was rotated slowly and pushed through the




probe while a continuous stream of acetone was run through it.  The brush




was also carefully cleaned and all washings collected in the glass jar.




The probe was finally eye-ball checked for transfer efficiency.




          The impinger train was Initially wiped clean on the outside




and all glassware connectors, including the filter, removed carefully




and all exposed surfaces wiped clean.  All the connectors were placed




on a piece of aluminum foil, ready for washing.  The first three impingers




were then analyzed for water collection by transferring the water through




the outlet port into a graduated cylinder and noting the volume.  The




impingers were not dismantled and all transfers and washings were performed




through the inlet and outlet ports.  All of the glassware in the back half




of the filter, up to the fourth impinger was then carefully washed with




distilled water and the washings collected.  This was followed by an




acetone wash which was again collected in a separate jar.

SRL 1281 0372









          Acetone washings from the glassware in the front half of the




filter were collected in the same jar as the probe and nozzle wash.




The filter was carefully removed from the holder and placed in a plastic




dish which was then sealed with tape.  Silica gel in the fourth impinger




was weighed in a previously tared glass jar using a triple-beam balance.




          All acetone jars had  aluminum lined lids., or aluminum foil




was used before screwing on the lids.  The following designations were




used for labeling the containers:




          Container //I:  Filter




          Container #2:  Acetone wash front half from filter




          Container #3:  Water wash back half from filter




          Container #4:  Silica gel




          Container #5:  Acetone wash back half from filter






2.  Laboratory Handling and Analysis




    a.  Filter Transfer




          Clean plastic dishes were desiccated for 24 hours, labeled and




tared on an electronic balance.  The filter containers were unsealed




and desiccated for 24 hours before carefully transferring the filters




to the tared dishes using a fine pair of tweezers.  Care was taken to




place a piece of aluminum foil under the transfer operation.  A "static-




master" brush was used to brush any fine particles adhering to the




container or foil.  All transfers were performed near the balance and




the weight reported to the nearest 0.1 mg.  The plastic dishes were




then sealed for shipment.

     b.   Acetone Washes




          250 ml. beakers were used for acetone wash transfers.  These




beakers  were leached for 24 hours in 50% nitric acid, washed thoroughly




and oven dried overnight.  These were then desiccated for 24 hours and




tared.  Once tared, the beakers were sealed with "parafilm".  Handling




of beakers was done as far as possible with tongs and "Kimwipes".




          All acetone glass jars were left loosely covered in a hood




until the acetone was evaporated.  This was found to be safer than




transferring the acetone into the tared beaker and evaporating.  Once




the acetone was evaporated, the glass jar was rinsed with acetone,




using a rubber policeman, and the washings collected in the tared beaker.




          Once the acetone evaporated in the beakers, the beakers were




desiccated for 24 hours and weighed to a constant weight.




          In some cases where water was present in the acetone wash, the




water was evaporated in an oven at 90 C after the acetone had all evaporated.




     c.   Water Wash Extraction




          Beakers tared as described before were used for collecting




the organic extract and the water wash after extraction.  The amount of




water collected was marked and the volume later measured and reported.




The water wash was transferred into a 2000 ml. extraction flask and




three 25 cc portions of chloroform used for the initial extraction.




Often when a large volume of water was collected (above 500 cc), a




fourth portion was used.  The extraction flask was shaken thoroughly,




and once the chloroform extract settled at the bottom, it was collected




directly in the tared beaker.

SRL 1281 15 0372







          Due to the large volume of water usually collected, three 50 ml.




portions of ether were used.  The ether extract separated at the top




and the water portion was collected in the original jars.  The ether




extract was then collected along with the chloroform extract.  Once all




the ether extract was collected, the extract portion was transferred




back into the extraction flask and the funnel and sides of the flask




rinsed with distilled water.  The chloroform and ether extract separating




at the bottom was then drained into the tared beaker and allowed to




evaporate in the hood before desiccating and weighing.




          The water portion was transferred to tared beakers, oven dried



at 90°C, desiccated and weighed.  All beakers were "parafilm" sealed for




shipment.




          The Project Officer requested that particle size analysis not




be performed.  Table D-l presents a summary of the measurements and




weight analysis for particulates.

                                TEST LOG




          The Eastern Associates Coal Company plant was located on the




north side of the railroad tracks in Keystone, West Virginia.  Figure 1




gives a rough schematic of the stack locations, the approximate dimensions




and the sampling setup used.  The main building was approximately 70 feet




to the top of the flat roof where the ports were located.  The sample




setup and transfer facilities were done in a relatively clean room




located in a single storied building about 100 feet east of the main




building.






Wednesday. February 23, 1972




          All the necessary equipment was hauled up and set up for the




initial flow traverse by about 1300 hours.  There was some shower activity




at this time, which increased in intensity by late afternoon.




          Some electrical grounding problems were encountered, possibly




due to the rain.  Grounding the meter box overcame this difficulty.  A




leak test was performed after the initial traverse and the first run




started at 1435.  Six points were sampled at each of three ports with




a time period of 7 minutes at each point.  The first run ended at 1648.




No problems were encountered in port transfer.




          The sample box configuration was modified for this site due




to the low height of the sample port from the flat roof (approximately 6").




The sample box had a special inlet on the backside and the impinger train




was placed facing away from the ports.

          The complete impinger train and the probe were carried to the




laboratory facilities where the sample transfer was accomplished.  Very




low particulate collection was noticed in this and the other two runs




performed at this site.  The halocarbon grease used for glassware




sealing was found to be attacked by acetone and hence it was advised




by the Project Officer not to collect a container #5 (acetone wash back




half)  for this run.  All glass ware cleanup and setup for the following




day were done at the Keystone laboratory facilities.




          The Project Officer also advised that it would be satisfactory




to collect a minimum 60 cubic foot sample rather than a minimum 90 cubic




foot sample.






Thursday, February 24, 1972




          Very heavy rain was encountered throughout most of the day.




Stopcock grease was obtained from the Bluefield State College and no




problems were encountered during sample transfer and glassware work.




Two runs were accomplished, the first one starting at 1155 and ending




at 1410, the second one from 1520 to 1735.  All sample transfer and




glassware wash were done at the laboratory facility.






Friday. February 25. 1972




          All equipment was unloaded, cleaned and packed for transfer




to next site by 1300 hours.
