I. INTRODUCTION
The National Enforcement Investigations Center (NEIC) conducted an
investigation of visible emissions from two stationary sources at the Gib-
son Generating Station operated by Public Service of Indiana (PSI), in
Princeton, Indiana, during the afternoon hours of June 16, 1980. Opacities
of observed visible emissions were measured remotely with a new instrumen-
tation method* using the NEIC Omega-1 Lidar. Figure 1 depicts the location
of the Lidar during the observations.
The Gibson Station contains four coal-fired generating units (Units 1
through 4) with each being equipped with an electrostatic precipitator
(ESP). Each of the units has a generating capacity of 650 megawatts. The
emissions from Units 1 and 2 are discharged through Stack A while the emis-
sions from Units 3 and 4 and discharged through Stack B. The height of
each stack is 500 ft. Visible emissions from these sources are alleged to
be in violation of the applicable opacity limits of the Indiana State Im-
plementation Plan (SIP).
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 Gibson Station.
To provide the requested assistance to Region V, NEIC conducted the
investigation with the following objectives:
1. Document the opacity of visible emissions from Stacks A and B.
2. Evaluate the compliance of the observed emissions with the
Indiana SIP.
* 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 two stationary sources with-
in the Gibson Generating Station, Public Service of Indiana (PSI), Prince-
ton, Indiana, were measured during the afternoon hours of June 16, 1980.
The sources investigated were Stacks A and B. All measurements were con-
ducted remotely from off the plant site.
Opacities were measured remotely with the NEIC Omega-1 Lidar which is
a new instrumentation method. The method has been proposed in the Federal
Register as Alternate Method 1 to Reference Method 9.
Four sets of opacity measurements were made, the total of which was
about 1 hour of observation and about 350 individual measurements. The
sets of measurements were 15 minutes in length. Measurements were made at
a temporal frequency range from once about every 8 to 9 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 each stationary source.
CONCLUSIONS
The visible emissions from Stacks A and B did not exceed the allowable
limit of the Indiana State Implementation Plan (40% for a 6-minute average)
at any time during the lidar observations.

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 PDP-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 Indiana State Implementation Plan (SIP), 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 SIP). The
6-minute interval remains constant although the number of opacity values
may vary above or below the nominal. In accordance with the Opacity Data
Acceptance/Rejection Criterion in Section 2.4.3, if the standard deviation,
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 40% (SIP) average opacity limit are indicated with a flag of
four asterisks.
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 SIP is indicated on
each plot by the dashed line at the 40% 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.
