I. INTRODUCTION
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.

II. SUMMARY AND CONCLUSIONS
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.
