     The National Enforcement Investigations Center (NEIC) conducted an in-
vestigation of  visible  emissions from one stationary  source  at  the A.  B.
Brown Generating  Station  operated  by  the  Southern  Indiana  Gas  and  Electric
Company (SIGECO),  in  West Franklin, Indiana, during the  late  morning  and
early afternoon hours of  June  17,  1980.   Opacities of observed visible
emissions were  measured  remotely with a new instrumentation method* using
the NEIC Omega-1  Lidar.   Figure 1  depicts  the location of  the  lidar during
the observations.

     The A.  B. Brown Station contains one coal-fired generating unit equip-
ped with an electrostatic precipitator (ESP) for particulate emissions con-
trol, and a scrubber  for  S02 control.  This  unit has a generating  capacity
of 250 megawatts.   The emissions from this unit are discharged through  the
Unit No. 1 Stack  which is  600 ft high.  Visible emissions  from this source
are alleged to  have been  in violation of  the New Source Performance Stand-
ard (NSPS).

     On April  21, 1980,  the Enforcement Division of EPA, Region V,  Chicago,
Illinois,  requested assistance   from NEIC  in documenting  the  opacity  of
emissions  from the A.  B.  Brown Station during daytime hours.

     To provide the requested  assistance  to Region V,  NEIC conducted  the
investigation with the following objectives:

     1.    Document the opacity of visible emissions from the Unit No.  1
          Stack.
     2.    Evaluate the compliance of the observed emissions with
          the NSPS.
*  This method has been proposed in the Federal Register,  Vol.  45,  No.  128,
   Tuesday, July 1, 1980,  pages 44329 through 44351,  as an alternate method
   to Reference Method 9.

SUMMARY OF INVESTIGATION

     The opacity of visible emissions from the one stationary source within
the  A.  B.  Brown  Generating Station, Southern  Indiana  Gas and Electric
Company (SIGECO), West  Franklin,  Indiana, was measured  during  late  morning
and  early  afternoon  hours on June 17, 1980.  The  source  investigated was
the  Unit No.  1  Stack.   All measurements were conducted remotely  from off
the plant site.

     Opacities were measured remotely with  the  NEIC Omega-1  Lidar which  is
a new instrumentation method.   This method has been proposed in the Federal
Register as Alternate Method I to Reference Method 9.

     Five sets of opacity measurements  were made, the  total of which was
about 1.25 hours of observation and  about 460 individual  measurement.  The
sets of measurements were 15 minutes in length.   Measurements were made at a
temporal frequency range from once about every 8 to 10 seconds.

     All opacity measurements were  subsequently analyzed and reduced with
the NEIC laboratory computer using the methods  given  in Alternate Method 1
(proposed).

     The results of  the lidar  observations are summarized in Table 1 ac-
cording to the official  designation of the stack.
CONCLUSIONS

     The visible emissions  from  the Unit No.  1 Stack exceeded the maximum
allowable limit of the New Source Performance Standards (20% for a 6-minute

average) during the  fourth  and fifth runs (Table 1).  The opacity of the
emissions exceeded the  limit  for a total of  24.75  minutes  or 83% of the
combined observation times.  The average opacity values were  less than 20%
throughout the first three data runs.

                             III.  METHODS
LIDAR OPACITY MEASUREMENTS

     Alternate Method  1  (proposed)  employs a lidar (lasar radar) which is
an optical  system  installed  in a truck-mounted van enclosure.  This mobile
lidar is  specifically  designed and  fabricated for measuring the  opacity of
visible emissions from a given stationary source during both day and night-
time ambient  lighting  conditions.   The laser transmitter within the lidar
emits a  short pulse of light.  The  lidar receiver collects the laser light
backscattered from the atmospheric  aerosols before and beyond the visible
plume as  well as that from the aerosols (particulates) within the plume.
The lidar receiver converts the backscattered optical  signals to electronic
signals or data.   The  Lidar has an inherent data processing capability that
calculates the opacity values  from  the backscatter data from just before
and beyond the plume.   It subsequently records these opacity values in hard
copy form, and also records the original lidar receiver data (signal  ampli-
tude vs range) on magnetic tape for future reference or use.

     The nominal  data gathering rate of the lidar is an opacity measurement
or determination once  every  10 seconds.  This data rate can be maintained
in continuous operation  for  minutes or even hours.  The  lidar method is
intended for use during nighttime,  as well  as during the day.

     The Omega-1 Lidar is  internally calibrated in the field periodically
over the opacity values of 0, 10,  20, 40,  60, and 80%.
DATA ANALYSIS AND REDUCTION

     The lidar data were analyzed in accordance with Section 2 of Alternate
Method 1 (proposed)  using the  NEIC  POP-11-70 laboratory computer.  The

-------
individual opacity values were  calculated using the backscatter data re-
corded on magnetic tape, with the opacity equation given in Section 2.4.1.
The associated  statistics which includes the standard  deviation,  S  ,  of
each individual opacity value,  were calculated  using the appropriate equa-
tions in  Section 2.4.1.  The running- or  sliding-average, Op, of the indi-
vidual  opacity  values was calculated over the 6-minute  averaging interval,
given in  the New Source Performance Standards (NSPS), according to the re-
quirements of Section 2.4.2.

     The  number of opacity values included in the running-average  is nomi-
nally 36  (six  measurements/minute  for  6 minutes according  to  the  NSPS).
The 6-minute interval remains constant although the number of opacity val-
ues may vary above  or below the nominal.  In accordance with the Opacity
Data Acceptance/Rejection Criterion in  Section 2.4.3,  if the standard devi-
ation,  S  , for  a  given  opacity value is greater than  8% (full  scale) then
that value is  discarded  from the running-average set  decreasing the  total
number by one.  The  number  of opacity  values in the 6-minute interval  may
be greater than 36 which is caused by the lidar data rate being set faster
than six opacity measurements/minute (one opacity measurement every 10 sec-
onds).
DATA PRESENTATION

     The opacity values are presented in two separate formats in Section IV
of this data  analysis  report.   For each data run the values are given  in
tabular form followed by graphic plots.   An identification header is locat-
ed across the top of the tabular form which provides the following informa-
tion:

          EPA-NEIC identification block.
          EPA-NEIC Omega control number (evidentiary parameter).
          Official designation for the stationary source.
          Facility name.
          Facility location.
          Location of the lidar during tests.
          Length of the running average interval.

-------
This tabular presentation provides the applicable data in columns identified
as follows:

          Date of data run.
          Time of the opacity measurement (nearest second).
          Opacity values as calculated in %.
          Standard deviation SO (S  in Alternate Method 1) in %.
          Individual violation flags, not applicable in Indiana.
          Average opacity (%) calculated over the running-average interval.
          Average standard deviation (%) calculated over the running-aver-
          age interval.
          Average opacity violation flag, applicable in Indiana.
          Number of opacity values discarded due to the Opacity Data
          Acceptance/Rejection Criterion (§ 2.4.3 of the Alternate
          Method 1).

In the average opacity violation  column, any violations that occurred over
and above  the  respective  20% (NSPS) average opacity  limit are indicated
with a flag of four asterisks.

     Referring to the  first  sheet of the tabular data output,  Section IV,
or the fifth  data  run,  (Omega-0071), the average  opacity  violation flag
(column 8 in the tabular  format)  does not show up until 6 minutes of data
have been  averaged.   If  the  average opacity is greater than 20%  then the
first violation flag  occurs  at the end of the first 6-minute interval and
continues until the average opacity drops below the regulation limit or the
data run is completed.  This data run began at 12:33:00 and the individual
opacity values were  nearly all  above 20% (column 3).   The average opacity
(column 6) reads zero  until  6 minutes of data have been recorded.  At the
end of the first 6-minute interval (12:33:00 to 12:38:54) the average opac-
ity was calculated  to  be  24% and the first average opacity violation flag
is indicated.

     The running-average permits  one  to easily locate the 6-minute inter-
val(s) which has the highest average opacity.  In  the example of  the  fifth

-------
data run  (Omega-0071),  the  highest average occurred for the 6-minute in-
terval  ending at 12:46:54 (sheet 2).   However, the first violation occurred
for the 6-minute time interval ending at 12:38:54.  The next violation does
not occur  until  6  minutes after 12:38:54 or 12:44:58 which had an average
opacity of 33%.

     A note  of  explanation  is provided for an occasional zero that may oc-
cur in the "Average  Opacity"  and the "Average SO" columns (column 6 and 7
in the tabular form) after the initial 6 minutes'  worth of data required for
the running-average has been recorded.  The computer data analysis software
is programmed so that  the 6-minute interval must be maintained to within
±15 seconds  or  the running-average is not calculated  for that particular
interval.   An example  is  provided  in  the fourth data run (run beginning at
12:02:13).   The  running-average  violation  flag (column 8)  is  missing at
12:13:42,   and the  Average Opacity  = 0 and Average So = 0.  This occurred
because the  temporal spacing  between  successive opacity measurements (12:
07:39 and  12:08:06)  were  27 seconds rather than  15 seconds.  During this
particular run the  lidar's laser was being  manually fired (laser usually is
fired automatically) and  the  operator missed activating the laser at the
proper time.  This can also occur  when,  in accordance with § 2.2.3 of Al-
ternate Method 1, lidar operation is temporarily suspended to obtain anoth-
er reference measurement.   The  computer  software places zero for the two
average parameters rather than performing the running-average with opacity
values  of zero for  the  missing data.

     The computer  graphical plots, located in Section  IV immediately after
each respective tabular data  set,  show the individual opacity values (col-
                                                       \
umn 3 of  the tabular data set) along with their respective standard devia-
tions as error bars (column 4 of the tabular data set).   The standard devi-
ation gives  an  indication of  the magnitude of  the  error  associated with
each opacity value due to atmospheric noise along the  lidar line-of-sight.
The magnitude of the average  opacity established in the NSPS is indicated
on each plot by the  dashed line at the 20% value.  Each graphical  plot is
fixed in time along the horizontal  axis,  being 10 minutes in length.

-------
     The lidar internal  calibration  data are presented in Table 1 of Sec-
tion II for each  respective  observation period as the extreme values that
occurred throughout the  opacity range given above.  A  negative value indi-
cates that the lidar  was determining opacity  low or below the respective
standard while a  positive value indicates a high value with respect to the
standard.
