I. INTRODUCTION
The National Enforcement Investigations Center (NEIC) conducted an
investigation of visible emissions from two stationary sources at the Ed-
wards Generating Station operated by Central Illinois Light Company
(CILCO), in Bartonville, Illinois, during the period from June 3 through 4,
1980. Opacities of observed visible emissions were measured remotely with
a new instrumentation method* using the NEIC Omega-1 Lidar. Figure 1 de-
picts the location of the Lidar during the observations.
The Edwards Station contains three boilers each being equipped with an
electrostatic precipitator. The participate emissions from boilers 1 and
2, generating capacities of 130 and 268 megawatts, respectively, are dis-
charged through Stack 1 which is 503 ft in height and the diameter is about
10.5 ft. The emissions from boiler 3, generating capacity of 350 mega-
watts, are discharged through Stack 2 being 503 ft high and about 12.5 ft
in diameter. Visible emissions from these sources are alleged to be in
violation of the applicable opacity limits of the Illinois State Implemen-
tation Plan (SIP) during the peak-power demand periods occurring in early
morning and late afternoon.
On April 21, 1980, the Enforcement Division of EPA, Region V, Chicago,
Illinois, requested assistance from NEIC in documenting the opacity of the
emissions from the Edwards Station during early morning and late afternoon
time periods.
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 1 and 2.
2. Evaluate the compliance of the observed emissions with the Illin-
ois SIP.
3. Evaluate if emissions from the Edwards Station were greater in
early morning hours than during the late afternoon period.
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 Edwards Generating Station, Central Illinois Light Company (CILCO),
Bartonville, Illinois, were measured during the period from June 3 through
June 4, 1980. The sources investigated were Stacks 1 and 2. Stack 1 was
observed during late afternoon and early morning hours. Stack 2 was ob-
served during early morning hours. All measurements were conducted remote-
ly 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.
All opacity measurements were subsequently analyzed and reduced with
the NEIC laboratory computer using the methods given in Alternate Method 1
(proposed).
Five sets of opacity measurements were made, the total of which was
about 1.75 hrs of observation and about 600 individual measurements. The
set of measurements ranged in length from 14 to 30 minutes. Measurements
were made at a temporal frequency range from once about every 9 to 10 sec-
onds.
The results of the lidar observation are summarized in Table 1 accord-
ing to the official designation of each stationary source.

CONCLUSIONS
The visible emissions from Stack 1 exceeded the maximum allowable
limit of the Illinois State Implementation Plan (30% for a 6-minute
average) each time the stack was observed. For three observation periods
ranging in length from 16 to 30 minutes, totaling 76 minutes, the emissions
exceeded the limit for 71 minutes or 93% of the observation time. The data
revealed that the emissions in late afternoon were significantly greater
than during the early morning hours.
The emissions from Stack 2 were observed through two observation
periods extending from 14 to 15 minutes. The emissions did not exceed the
SIP opacity limit (30% for a 6-minute average) during these times.

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 siiding-average, Op, of the indi-
vidual opacity values was calculated over the 6-minute averaging interval,
given in the Illinois State Implementation Plan (SIP), according to the
requirements 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 Illinois.
Average opacity (%) calculated over the running-average interval.
Average standard deviation (%) calculated over the running-aver-
age interval.
Average opacity violation flag, applicable in Illinois.
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 30% (SIP) average opacity limit are indicated with a flag of
four asterisks.
Referring to the first sheet of the tabular data output, Section IV,
for the first data run, (Omega-0044), the average opacity violation flag
(column 8 in the tabular format) does not show up until 6 minutes of data
has been averaged. If the average opacity is greater than 30% 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 18:46:38 and the individual
opacity values were all above 30% (column 3). The average opacity (column
6) reads zero until 6 minutes of data has been recorded. At the end of the
first 6-minute interval (18:46:38 to 18:52:19) the average opacity was cal-
culated to be 79% and the first average opacity violation flag is indicat-
ed.
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 first
-------
data run (Omega-0044), the highest average occurred for the 6-minute inter-
val ending at 18:56:27 (sheet 2) and continued until 19:00:43 (sheet 2).
However, the first violation occurred for the 6-minute time interval ending
at 18:52:19. The next violation does not occur until 6 minutes after
18:52:19 or 18:58:19 which had an average opacity of 80%. The third con-
secutive violation occurred at 19:04:23 with an average opacity of 78%, and
so forth.
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 par-
ticular interval. An example is provided in the first data run for Stack
1. The running-average violation flag (column 8) is missing from 18:52:39,
and the Average Opacity = 0 and Average SO = 0. This occurred because the
temporal spacing between successive (one or several) opacity measurements
were greater 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 Alternate Method 1, lidar opera-
tion is temporarily suspended to obtain another reference measurement. An
example of this effect is seen on page 1 of fourth data run (Stack 1).
Seven consecutive values of "Average Opacity" and "Average SO" were zero.
During the applicable 6-minute time interval the lidar operation was sus-
pended from 07:45:38 to 07:47:11; i.e., 1 minute, 33 seconds. 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 SIP is indicated on
each plot by the dashed line at the 30% 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.
