                           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.

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.
