I. INTRODUCTION
The National Enforcement Investigations Center (NEIC) conducted an
investigation of visible (particulate) emissions from various stationary
sources at the El Paso Smelting Works operated by ASARCO, Inc. in El Paso,
Texas, during the period from December 3 to 6, 1979. Opacities of observed
visible emissions were measured remotely with a new instrumentation method
using the NEIC Omega-1 Lidar. EPA Region VI representatives collected
in-plant data during the last two days of this investigations.
The El Paso Smelting Works is a copper smelter and associated faci-
lities for recovery of lead, zinc and by-product sulfuric acid. Visible
emissions from this facility are alleged to be in violation of the appli-
cable opacity limits of Texas Regulation Rule 103 and the State Implementati
Plan (SIP). The excessive emissions are alleged to occur more frequently
at night.
On October 25, 1979 the Enforcement Division of EPA Region VI, Dallas,
Texas, requested assistance from NEIC in documenting the opacity of emis-
sions from the ASARCO facility during both day- and night-time hours.
Specifically the Enforcement Director requested that the Omega-1 Lidar be
available in El Paso during the week of December 3 to assist a Region VI
inspection team.
To provide the requested assistance to Region VI, NEIC conducted the
investigation with the following objectives:
1. Document the opacity of visible emissions from specific sources
designated by Region VI inspection team.
2. Evaluate the compliance of the observed emissions with the
applicable regulation.
3. Evaluate if emissions from the ASARCO facility do increase at
night above levels observed during the day.
-------
II. SUMMARY AND CONCLUSIONS
SUMMARY OF THE INVESTIGATION
The opacity of visible emissions from six stationary sources within
the ASARCO, El Paso Smelting Works, El Paso, Texas, were measured during
the period from December 3 through December 6, 1979. The sources investi-
gated were the copper, No. 2 acid, lead and zinc stacks, the blast furnace
bag house, and the converter building roof monitor.
Opacities were measured remotely with the NEIC Omega-1 Lidar which is
a new instrumentation method. This method is in the EPA review process and
will be proposed soon as Alternate Method 1 to Reference Method 9.
Nineteen sets of opacity measurements were made, the total of which
was about ten hours of observation and about 4,200 individual measurements.
The sets of measurements ranged in length from 10 to 61 minutes. Measure-
ments were made at a temporal frequency range from once every four seconds
to once every ten seconds.
Opacity measurements were made at night on December 3 and 4, and dur-
ing the day on December 4, 5 and 6. The copper, lead and zinc stacks were
observed during both day-and nighttime hours. The No. 2 acid stack, the
blast furnace bag house and the converter building roof monitor were
observed only during the day. All measurements were conducted remotely
from off the plant site.
The Region VI inspection team conducted an in-plant inspection on
December 5 and 6, 1979. The plant data collected are not included in this
data analysis report.
-------
All opacity measurements were subsequently analyzed and reduced with
the NEIC laboratory computer using the methods prescribed in Alternate
Method 1.
The results of each lidar observation are summarized in Table II-1
according to the official designation of each stationary source.
CONCLUSIONS
The visible emissions from the copper stack exceeded the maximum
allowable limit of Texas Regulation Rule 103 and the State Implementation
Plan (30% for a 5-minute average) each time the stack was observed. For
the nine observation periods ranging in length from 15 to 61 minutes,
totaling 341 minutes, the emissions exceeded the limit for 317 minutes or
93% of the observation time.
The emissions from the No. 2 acid stack exceeded the 20% limit of the
SIP 99% of the observation time (three observation periods, 111 minutes out
of a total of 112).
The emissions from the lead stack were observed through three obser-
vation periods extending from 15 to 31 minutes. The emissions exceeded the
20% limit of the SIP during the first observation (Table II-l). The total
observation time was 61 minutes and the source emissions exceeded the limit
29 minutes, 48% of the test time.
The emissions from the zinc stack exceeded the 30% limit of the SIP
for 30 out of 45 minutes or 67% of the observation time (two observation
periods).
The converter building roof monitor emissions were observed for a
10-minute period with the peak opacity (5 minute average) being 24%. The
limit of the emissions have not been established in the SIP and no

determination was made for excess times during lidar data processing/
reducti on.
From the data analysis summary presented in Table II-l, it appears
that the opacity of the copper stack's visible emissions were greater at
night than during the day based on six observations at night as opposed to
three during daylight hours. The emissions from the No. 2 acid stack were
observed only during the day. The opacity of the lead stack's emissions
were much greater at night than for the daytime observations. The same
conclusions holds true for the zinc stack's emissions. The emissions from
the blast furnace bag house and the converter building roof monitor were
observed only during daylight hours.
-------
III. METHODS
LIDAR OPACITY MEASUREMENTS
Alternate Method 1 (to be 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. From the data (just before and
beyond the plume) the plume opacity is subsequently calculated and printed
in hard copy format along with the date and time to the nearest second.
The nominal data gathering rate of the lidar is an opacity measurement or
determination once every ten seconds.
This rate can be maintained in continuous operation for minutes or
even hours. The lidar has an inherent data processing capability that
calculates the opacity values, subsequently records these opacity values in
hard copy form, and also records the original lidar receiver data (signal
amplitude vs range) on magnetic tape for future reference or use. This
method is intended for use during night-time hours as it is during the day.
This is a most important capability in the measurement of stationary source
emissions opacity.
Data Analysis, Reduction and Presentation
The lidar data were analyzed in accordance with Alternate Method 1 (to
be proposed), and reduced according to NEIC's standard methods.
-------
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. The tabular form provides the
following information:
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.
Date of data run.
Time of the opacity measurement (nearest second).
Opacity value as calculated in %.
Standard deviation SO (S in Alternate Method 1) in %.
o
Individual violation flags not applicable in Texas.
Average opacity (%) calculated over the 5-minute interval.
Average standard deviation (%) calculated over the 5-minute
i nterval.
Average opacity violation flag, applicable in Texas.
Number of opacity values discarded due to the Opacity Data
Acceptance/Rejection Criterion (§ 2.5.3 of the Alternate
Method 1).
Although the lidar computer calculates plume opacity for each measure-
ment at the time it was made, the lidar data (recorded on magnetic tape)
was subjected to the data analysis/reduction at EPA-NEIC on the laboratory
computer. In addition, this computer calculates the running or sliding
average of the individual opacity values over the 5-minute interval, in the
case of Texas Regulation Rule 103 and the State Implementation Plan (SIP),
and flags any violations that occurred over and above the respective 20 or
30% average opacity limits.
The number of opacity values included in the running average are
nominally 30 (six measurement per minute for five minutes according to
-------
the SIP. The 5-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 mentioned above, if the
standard deviation, Sq, 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 5-minute
interval may be greater than 30 which is caused by the lidar data rate being
set faster than six opacity measurements per minute (one opacity measure-
ment every ten seconds).
Referring to the first sheet of the tabular data output, Section IV,
for the first data run, (Omega-0023), the average opacity violation flag
(column 8 in the tabular format) does not show up until five minutes of
data has been averaged. If the average opacity is greater than 30% (or 20%
whichever is applicable) then the first violation flag occurs at the end of
the first 5-minute interval and continues until the average opacity drops
below the regulation limit or the data run is completed. This data run began
at 17:24:00 and the individual opacity values were all above 30% (column
three). The average opacity (column six) reads zero until five minutes of
data has been recorded. At the end of the first 5-minute interval
(17.24:00 to 17:28:50) the average opacity was calculated to be 51% and the
first average opacity violation flag is indicated.
The running average permits one to easily locate the 5-minute
interval(s) which has the highest average opacity. In the examples of the
first data run (0mega-0023), the highest average occurred for the 5-minute
interval ending at 17:32:20 (sheet two) and again at 17:54:09 (sheet four).
However, the first violation occurred for the 5-minute time interval ending
at 17:28:50. The next violation does not occur until five minutes after
17:28:50 or 17:33:50 which had an average opacity of 52%. The third consec-
utive violation occurred at 17:38:51 with an average opacity of 51%, and so
forth.
A note of explanation is provided for an occasional zero that may
occur in the "Average Opacity" and the "Average SO" columns (columns six
-------
and seven in the tabular form) after the initial five minutes worth of data
required for the running average has been recorded. The computer data
analysis software is programmed so that the 5-minute interval must be
maintained to within ±10 seconds or the running average is not calculated
for that particular interval. An example is provided in the third data run
for the Copper Stack (12-3-79, run beginning at 18:44:00). The running
average violation flag (column eight) is missing from 18:49:51, and the
Average Opacity = 0 and Average SO = 0. This occurred because the temporal
spacing between 18:44:50 and 18:45:05 was 15 seconds rather than ten. The
latest opacity measurement should have occurred at 18:45:00, five seconds
earlier. During this particular run the lidar's laser was being manually
fired (laser usually is fired automatically) and the operator missed acti-
vating the laser at the proper time. This can also occur when, in accord-
ance with § 2.2.3 of Alternate Method 1, lidar operation is temporarily
suspended to obtain another reference measurement. An example of this
effect is seen on page three of the above mentioned data run. Five
consecutive values of "Average Opacity" and "Average SO" were zero. During
the applicable 5-minute time interval the lidar operation was suspended
from 19:02:30 to 19:03:41, i.e., one minute, 11 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
(column three of the tabular data set) along with their respective standard
deviations as error bars (column four of the tabular data set). The standard
deviation gives an indication of the magnitude of the error associated with
each opacity value due to atmospheric noise along the lidar 1ine-of-sight.
The magnitude of the average opacity established in the SIP is indicated on
each plot by the dashed line at the 20 or 30% value. Each graphical plot
is fixed in time along the horizontal axis, being ten minutes in length.
The 0mega-l Lidar is internally calibrated in the field periodically
over the opacity values of 0, 10, 20, 40, 50, and 80%. These calibration
-------
data are presented in Table II-1 for each respective observation period as
the extreme values that occurred throughout the opacity range given above.
A negative value indicates 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
