ABSTRACT
The Large Power Plant Effluent Study (LAPPES) was initiated during 1967 in
western Pennsylvania to evaluate the extent and effects of air pollution resulting
from the largest complex of coal-burning generating stations in the United States.
During 1971 two series of LAPPES field experiments were conducted in areas sur-
rounding the Conemaugh and Keystone Generating Stations; these experiments con-
sisted of ground-based and airborne plume measurements supported by extensive
meteorological observations. Part 1 of this volume describes the topography and
climatology of the generating station complex, the sulfur dioxide and meteoro-
logical monitoring equipment, and experimental procedures. Part 2 presents tabu-
lations of plant operational parameters and the air quality and meteorological data
collected during 1971. Part 3 consists of a summary of the entire LAPPES project;
included are series tabulations of air quality and meteorological data collected by
LAPPES personnel from 1967 through 1971 and descriptions of contractor participation
and the LAPPES vegetative study.

AND PROJECT SUMMARY
INTRODUCTION
Cognizant of the need for clean air, the electric power industry in many in-
stances has adopted the tall stack in its endeavor to maintain reasonable air
quality at ground-level surrounding generating stations of ever increasing capacity,
Considerable debate is underway, however, on both the national and international
scene regarding the effectiveness and performance of these stacks in overall pollu-
tion management. Questions raised by health and air pollution control agencies
regarding the potential effects of airborne effluents from these plants cannot be
answered in a definitive way by simply extrapolating experience with existing
smaller-capacity installations. Accordingly, the Environmental Protection Agency
(EPA) has conducted a 5-year comprehensive field study to determine the extent and
effects of power plant emissions from tall stacks. Specifically, three objectives
were pursued at the Western Pennsylvania site:
1. To develop and validate transport and diffusion models with which to
calculate ground-level concentrations of effluents from large power plants with
tall stacks.
2. To measure the magnitude, frequency, and spatial distribution of ground-
level concentrations from large power plants with tall stacks, singly and in
combination, and to compare the observed data with calculated predictions.

-------
3. To evaluate the effects of sulfur compounds and other effluents from a
large power plant complex on vegetation in the region of the installations.

The LAPPES project was sponsored by the Environmental Protection Agency, with
field activities conducted by on-site personnel. Office facilities were maintained
at Jimmy Stewart Airport in Indiana, Pennsylvania. Also cooperating in the study
were the Pennsylvania Electric Company and the Division of Air Pollution Control of
the Pennsylvania State Department of Health. During the 1971 field experiments,
additional contract participation was provided by Brookhaven National Laboratory.

LAPPES consisted of two complementary efforts, the first concerned with meteor-
ological and air quality measurements and the second with agricultural effects
data. The meteorological portion of the study was conducted along three inter-
related lines of investigation: (1) determination of plume rise under a variety of
atmospheric conditions; (2) determination of plume dispersion, both vertical and
horizontal, as a function of downwind distance and atmospheric conditions; and
(3) determination of the magnitude, areal extent, and occurrence frequency of sul-
fur dioxide concentrations at ground level after emission from tall stacks. The
agricultural or vegetative segment of LAPPES attempted to evaluate effects of power
plant emissions on the agricultural economy of the adjacent region, which consists
largely of Christmas tree plantations.
The purpose of this volume is to present the meteorological and air quality
data collected during 1971 in support of the first two LAPPES objectives and to
present a summary of the entire LAPPES project. Specifically, Part 1 describes
the power station complex and the equipment, procedures, and techniques used in
conducting field experiments, in measuring air quality and meteorological parameters,
and in reducing and processing data. Part 2 presents tabulations of the basic
data and pertinent supplementary data collected during 1971. Part 3 summarizes
the various types of air quality and meteorological data collected by LAPPES person-
nel from 1967 through 1971 and describes contractor participation and the LAPPES
vegetative study.
This volume is not intended to present analyses of the data, to evaluate
existing plume rise and dispersion theories, or to develop new diffusion models;
these objectives have been pursued in related papers (Niemeyer et al., 1970; Pooler
and Niemeyer, 1970; Schiermeier, 1971a) and will receive additional treatment in
future work. Previous publications dealing with LAPPES include a general descrip-
tion of the project goals and activities (Niemeyer and Schiermeier, 1969) and three
volumes containing data collected during similar field studies conducted around the
Keystone, Homer City, and Conemaugh Generating Stations from 1967 through 1970
(Schiermeier, 1970; Schiermeier, 1971b; Schiermeier and Niemeyer, 1970).

PART 1 - INSTRUMENTATION AND PROCEDURES
POWER PLANT DESCRIPTION
The largest complex of coal-burning generating stations in the United States
has emerged in the Chestnut Ridge area of Western Pennsylvania shown in Figure 1.
Three new mine-mouth stations, Keystone, Homer City, and Conemaugh, are located
approximately equidistant along a NW-SE line 39 kilometers long about 80 kilometers
ENE of Pittsburgh. These three plants, combined with the nearby Seward and Shaw-
ville Stations, form a complex whose total annual production of 47,380,505 megawatt-
hours exceeds the total yearly electrical output of all but 11 nations of the world.
The five stations, owned by a total of 12 electric utilities, are fed from coal
mines located either directly under or close by the station sites.

The subject of LAPPES was the line of sources formed by the Keystone, Homer
City, and Conemaugh Stations, whose stacks emit a combined daily output approaching
2000 metric tons of sulfur dioxide into the atmosphere. A distinct advantage of
this location for the study is that air quality measurements progressed as each
stack of each station became operational. The 1967 and 1968 LAPPES field studies
were conducted in an area surrounding the Keystone Station. Beginning in 1969, the
project area was expanded to encircle the Homer City Station as it became opera-
tional, with similar expansion effected in 1970 to include the Conemaugh Station.
In the following description of the power station complex, generating capac-
ities are based on design specifications. These optimum plant loads have been
temporarily down rated to allow for necessary equipment modifications but should
be restored to their original levels in the near future. This slight decrease in
plant rating has no effect on the data contained herein because existing hourly
plant loads are included in Table 12 for the periods of plume sampling.
Keystone Station
The Keystone Generating Station, located just west of Shelocta, was the first
of the three new mine-mouth stations to be completed (Figure 2). The station has
an hourly generating capacity of 1.55 x 1012 calories (1800 megawatts) produced by
two identical cross-compound turbine-generator units. The boilers, which hourly
produce 1.81 x 1012 calories, consume 590 metric tons of pulverized coal per hour
supplied by conveyor and truck from nearby mines. Four 99-meter-tall natural-draft
cooling towers are used to provide recirculating water for steam condensation. The
towers are designed to collectively cool 21.2 x 105 liters of water per minute from
48°C to 32°C with a total evaporation rate of 34,000 to 49,000 liters per minute.

-------
Boiler effluent is fed to the twin 244-meter-tall stacks after passing through
two electrostatic precipitators per unit. The precipitators, with an efficiency
rating of 99.5 percent, remove a combined total of 83 metric tons of flyash hourly.
Each stack includes a 9.5-mm-thick steel liner that maintains a constant outside
diameter of 11.0 meters from the base to a height of 27 meters, and a diameter of
8.3 meters from a height of 58 meters to stack top; the taper from 11.0 to 8.3
meters occurs between 27 and 58 meters above the base. Surrounding the liner is a
concrete shell tapering from an outside base diameter of 20.4 meters to ~0.4 meters
at the top. Separation between stack centers is 61.9 meters, and the inside (exit)
diameter at the top is 8.29 meters. Orientation of the stacks is along a line
044°-224° from north.

Unit 1 of the Keystone Station went into commercial operation during August
1967; unit 2 followed in July 1968 (Estrada and Smith, 1964; Penelec, 1971).
Homer City Station
Second in line is the Homer City Station, which is located about 4 kilometers
SSW of the Homer City Borough (Figure 3). The station is capable of generating
1.10 x 1012 calories hourly (1280 megawatts) by means of two tandem-compound
turbine-generator units. The boilers produce 1.28 x 1012 calories an hour while
consuming 420 metric tons of finely ground coal supplied by conveyor from two
nearby mines. Two 119-meter-tall natural-draft cooling towers provide recircu-
lating water to condense steam back into boiler water. Approximately 15.7 x 105
liters of water are cooled from 49°C to 32°C each minute; total evaporation rate is
30,000 to 42,000 liters per minute.

Boiler effluent reaches the two 244-meter-tall stacks after passing through
four electrostatic precipitators that remove a total of 71 metric tons of flyash
hourly. Each chimney includes a 6.35-mm-thick steel liner that tapers from 10.0
meters outside diameter at the base to 7.3 meters at a height of 55 meters; the
top 189 meters of the liner maintains a constant outside diameter of 7.3 meters.
Surrounding the liner is a concrete shell tapering from an outside base diameter
of 19.1 meters to 9.5 meters at the top. Separation between stack centers is
53.0 meters, and the inside (exit) diameter at the top is 7.29 meters. Orientation
of the stacks is along a line 160°-340° from north.
The Homer City Station is so designed that a third unit with associated stack
and cooling tower may be added if required. Unit 1 went into commercial operation
during July 1969; unit 2 followed in December 1969 (Penelec, 1971).
Conemaugh Station
The third new generating station, Conemaugh, is situated at the village of
Huff on the Conemaugh River (Figure 4). The Conemaugh Station is the near twin of
Keystone, with identical boiler production and coal consumption. Also similar is
4

-------
the hourly generating capacity of 1.55 x 1012 calories (1800 megawatts). Because of
their larger size and capacity, however, only two cooling towers, each 113 meters
tall are required. Approximately 21.2 x 105 liters of water are cooled from
48°C to 32°C each minute to provide recirculating water for steam condensation;
total evaporation rate is 34,000 to 49,000 liters per minute.

The Conemaugh Station is similarly equipped with precipitators that will
ensure removal of up to 100 metric tons of flyash hourly from the boiler effluent.
The two 305-meter stacks are constructed of a 22.2-mm-thick steel liner encased in
a tapered concrete shell ranging from an outside base diameter of 25.3 meters to a
top diameter of 10.3 meters. The steel liner maintains a constant diameter of 11.0
meters from the base up to a height of 27 meters, and 8.3 meters from a height of
58 meters to stack top; the taper from 11.0 to 8.3 meters occurs between 27 and 58
meters above the base. Separation between stack centers is 61.9 meters, and the
inside (exit) diameter at the top is 8.29 meters. Orientation of the stacks is
along a line 101°-281° from north.
Unit 1 of the Conemaugh Station went into commercial operation during May 1970;
unit 2 followed in May 1971 (Penelec, 1971).
TOPOGRAPHY AND GENERAL CLIMATOLOGY
As shown by the topographic map in Figure 5, the generating stations are
located in the Chestnut Ridge sector of the Allegheny Mountains. Typical of this
area of Pennsylvania are numerous creeks and rivers, and rolling hills rising 100
to 200 meters above the valley floors. The land, much of which is tree covered,
slopes generally upward to the east to form the foothills of the Allegheny
Mountains. Prominent features include Chestnut Ridge, oriented NE-SW and situated
between the Homer City and Conemaugh Stations, and the considerably higher Laurel
Ridge immediately southeast of the Conemaugh Station.

The Keystone Station is situated in a shallow rural valley with stack base
elevation at 305 meters above mean sea level (MSL). Except for this valley, the
surrounding terrain within 5 kilometers is hilly, with the tallest peaks attaining
approximately mid-stack height. Influences of large-scale topography are not evi-
dent from past ground-level measurements of Keystone emissions, although there may
be some subtle effects that could appear during further analyses of the data.
The Homer City Station is located on a plateau with much of the surrounding
terrain at approximately the same elevation as stack base at 366 meters MSL. To
the east of the plant is a drop of about 100 meters to a valley, on the opposite
side of which is Chestnut Ridge, with peaks ranging slightly higher than mid-stack.
East of the ridge is a plateau that received higher S02 concentrations at ground
level than were found at comparable distances in other dirPL+~Qn~ ~rom the Homer
5

-------
City Station. This appeared to be caused in part by a lee effect and was not
attributable solely to the elevation of the plateau.

The Conemaugh Station is most susceptible to topographic influences. Sepa-
rating this plant from Johnstown is the Laurel Ridge with some peaks within 6
kilometers ranging up to 200 meters above stack top. Stack base elevation at this
plant is 329 meters MSL. During the October 1970 series, and to a lesser extent
during the October 1971 series, helicopter and ground-based measurements confirmed
the unique dispersion characteristics in the area. With moderate to strong flow
from the southeast quadrant, the plume was brought to the surface within a very
short distance; on one occasion, it appeared to descend onto the generating station
itself. The S02 concentrations rapidly diminished with distance to the northwest
but increased slightly on the lee side of Chestnut Ridge, about 12 to 14 kilometers
from the Conemaugh stacks. In addition to ground-level S02 measurements, this down-
wash on the lee side of Laurel Ridge was confirmed by actual subsidence of pilot
balloons in the vicinity of the Conemaugh stacks.
Accompanying this downwash phenomenon was a persistent cloud cover over the
Conemaugh Station, caused by upslope action over Laurel Ridge. Observed cloud
bases varied between 450 and 650 meters above stack base elevation with coverage
ranging from scattered to overcast, although usually broken. This cloud deck fre-
quently extended as far northwest as Chestnut Ridge, with clear skies beyond. The
lee downwash appeared to be associated with neutral ~low because on days when the
cloud cover dispersed sufficiently to allow surface heating, the downwash ceased
and the plume rose in a normal manner.
With winds from the opposite direction, i.e., the northwest quadrant, the plume
rose over Laurel Ridge and apparently mixed through a deep layer in the lee of the
ridge; relatively low concentrations were measured from ground level to the
upper limit of sampling imposed by cloud bases. If a lee-wave phenomenon exists
with northwest winds, it has not been detected by our sampling methods.

During the April 1971 series, the Conemaugh plume was discovered to be inter-
cepting ridges at considerable distances from the plant (11 to 20 kilometers) and
flowing smoothly down the lee side for about 1 or 2 kilometers before rising again.
That this phenomena was not confined to a particular wind direction was evidenced
by the various azimuths of occurrence, 275°, 327°, 353°, and 060°. Two meteoro-
logical characteristics common to all four occurrences were the presence of
strong surface inversions near the Conemaugh Station shortly after sunrise and the
sudden disappearance of the high ground-level S02 concentrations in the lee of the
ridges as surface heating commenced.
The area of study has a humid, continental type of climate modified slightly by
its nearness to the Atlantic Seaboard and the Great Lakes. Summers are mild but
f

-------
frequently humid because of invasions of air from the Gulf of Mexico. Winters are
reasonably brisk with occasional periods of extreme cold; spring and fall months
have moderate to cool temperatures. Precipitation is well distributed throughout
the year, with appreciable snowfall in winter and the maximum frequency of thunder-
storms in early summer.
Surface inversions are relatively frequent during the warmer months of the
year; in winter, however, cloudiness persists because of this area's proximity to
the track of west-east migratory storms and the frequent showery weather associated
with northwest winds across the Great Lakes. Cold air dr.ainage induced by the many
hills leads to frequent formations of early morning fog, which may be quite per-
sistent in the deeper valleys during the colder months. The study area is also
subject to relatively frequent occurrences of stagnating anticyclones, a condition
conducive to high. ambient pollution levels because of the resulting poor ventilation
HELICOPTER INSTRUMENTATION *
The primary source of airborne plume and meteorological measurements was an
instrumented Bell model 47J2 helicopter. The instrument package was designed and
fabricated by Sign X Laboratories of Essex, Connecticut, and provided the observer
with continuous, near-instantaneous measurements of sulfur dioxide and pressure
height on the top recorder, and temperature and wet-bulb depression on the bottom
(Figure 6). A description of the system follows (Sign X, 1970):
1. Sulfur dioxide: electroconductivity method with time constant of 2.0 to
2.5 seconds; four ranges with full scale 1.0, 5.0, 10.0, or 50.0 ppm; flow rate of
air sample, 2500 cc/min; flow rate of reagent, 25 cc/min; temperature compensation
in analytical cell of 2.0 percent per degree C based on 25°C; sulfur dioxide removal
from reagent (distilled water) accomplished by ion exchange resin.
2. Pressure height: double bourdon cell with time constant of 0.1 second;
electrical output linear function of pressure height according to standard atmos-
phere; four overlapping scales with 200 meters = 25.4 mm (1.0 inch) on chart.
3. Temperature: thermistor with time constant of 0.1 to 0.2 second; three
overlapping scales with 4°C = 25.4 mm (1.0 inch) on chart.
4. Wet-bulb depression: thirty-junction thermopile with time constant of
0.1 to 0.2 second; one scale with 4°C = 25.4 mm (1.0 inch) on chart.
5. Sulfur dioxide scrubber: manually operated, water- and resin-activated;
two identical inline tubes provided equivalent pressure drop whether scrubbing or
sampling directly.
*Mention of commercial products or company names does not constitute endorsement by
the Environmental Protection Agency.

-------
6. Recorders: Hewlett Packard Model 7100B; two-channel with plug-in modules;
full scale for each pen equivalent to half chart width with 2.54-mm vertical pen
displacement to prevent collision in the event of overlap; one minute marker and
one event marker on each recorder; chart speed = 25.4 mm (1.0 inch) per minute.

The instrument package was mounted in the left passenger cockpit position,
facing the observer, so that continuous monitoring of all four parameters could be
maintained (Figure 7). Power was supplied by the aircraft 24-volt DC power supply,
subsequently converted to 115 volts AC by means of a Topaz static inverter con-
tained in the baggage compartment.

The pressure-height sensor, attached to the lower right brace of the instru-
ment package, was connected by means of Teflon tubing to the static line of the
helicopter airspeed indicator. The remaining three sensors were externally mounted
on the left skid (Figure 8). The temperature and wet-bulb depression sensors were
located respectively fore and aft in the 75-mm-diameter cylinder with the reservoir
for the wet-bulb occupying approximately one-fourth the inner volume. The air
intake to the S02 analyzer was a 3.17-mm-interior-diameter (10) Teflon tube
inserted into the trailing edge of the 1.8-meter-long, 22.2-mm-ID steel pipe
attached to the skid.

With an airflow of 2500 cc/min into the analyzer and a Teflon'orifice in the
probe of 1.19-mm 10, the isokinetic sampling speed for this unit was calculated as
24.3 mps. Actual flights were conducted at 22.4 mps (50 mph) during 1971. Disturb.
ance of air at the sampling inlets by downwash from the helicopter rotor occurred
only when the craft was hovering and not during forward flight. Communication be-
tween the airborne observer and ground-based sampling teams was accomplished by
means of Motorola Motrac FM two-way radios.
SULFUR DIOXIDE INSTRUMENTATION
Portable Bubblers
The portable bubblers used to measure ground-level S02 concentrations under
the plume were constructed by EPA personnel and designed to obtain six consecutive
30-minute samples (Figure 9). The units were powered by 7.5-volt batteries and
maintained an average flow rate of 150 cc/min. Each of the six sampling tubes per
bubbler contained 20 ml of West-Gaeke solution through which ambient air was drawn
by a 200-cc/min-capacity pump driven by a 6-volt motor. Additional tubes con-
taining glass wool were installed downstream to prevent moisture from entering the
pump assembly.
Switching between sampling tubes was accomplished by means of a synchronous
timing motor and sequential valve. Because the sampling probe was only 15 cm above
ground when operating, Millipore filters were inserted near the inlets to prevent
8

-------
admission of particulate matter.
Technicon AutoAnalyzer.
Analyses of bubbler samples were performed on a
Technicon AutoAnalyzer
The LAPPES office at Jimmy Stewart Airport was equipped with a Technicon Auto-
Analyzer that served the dual purpose of analyzing bubbler samples and monitoring
ambient S02 (Figure 10). The S02 was measured colorimetrically. using West-Gaeke
solution as the absorbing reagent, with sulfamic acid added to depress interference
from nitrogen dioxide. Components of the AutoAnalyzer included a sampler, propor-
tioning pump, heating bath, programmer, and colorimeter-recorder.

When this AutoAnalyzer was used for on-stream monitoring, the flow rates of
air and West-Gaeke solution through the absorbing column were 1 liter/min and 1.5
cc/min respectively. Ambient air was drawn through Teflon tubing from the intake
on the office roof, 12 meters above surface; a Millipore filter was used tQ screen
out airborne particulate matter. When the instrument was used to analyze bubbler
samples, the intake line from the absorbing column was switched to the sampler
turntable where bubbler reagent was contained in individual sample cups.
The transmittance of the colored complex was measured at 572 m~ with a 50-mm
flow cell in the colorimeter. Calibration curves for data reduction were computed
by analyzing standards each time new reagents were prepared (Technicon, 1966).
METEOROLOGICAL INSTRUMENTATION

Fixed Network at Jimmy Stewart Airport
Several meteorological variables were routinely monitored at Jimmy Stewart
Airport to provide supplementary data for LAPPES experiments; these included wind
speed and direction, temperature, relative humidity. hourly precipitation, and
solar radiation (Figure 11). The surface elevation for these observations was 427
meters MSL, which corresponded to mid-height of the Keystone stacks, one-quarter
height of the Homer City stacks, and one-third height of the Conemaugh stacks.
The Aerovane wind transmitter was mounted on a 10-meter tower as shown in
Figure 11. Because of a nearby active runway. the FAA required that the tower be
erected within 25 meters of the two-story office building. Winds from the quadrant
centered on 0900 may have been affected by the obstruction and should be so regarded
in the ensuing data summary.
The Aerovane was equipped with a six-bladed impeller whose starting speed was
about 0.7 mps; wind direction was sensed by the streamlined vane. Values for the
wind speed and direction were electrically transmitted, and recorded continuously on
a two-channel recorder. Range of wind speed was 0 to 44.7 mps (0 to 100 mph) on one
channel; range of wind direction was 540 degrees of azimuth, allowing for crossover,
on the other channel. Speed of chart rotation was 76.2 mm (3.0 inches) per hour.
9

-------
Hourly temperature and relative humidity values were obtained from a standard
National Weather Service hygrothermograph positioned in a louvered "cotton-region
type" shelter. Maximum and minimum thermometers and a sling psychrometer were used
to maintain calibration on the hygrothermograph. Precipitation totals were ob-
tained from a weighing-bucket rain gage with verification provided by a standard
20.32-cm (8-inch) gage.

An Eppley pyranometer provided hourly values of total sun and sky radiation.
Measurements were produced as a result of a voltage difference between two exposed
concentric rings, one painted with lampblack, the other smoked with magnesium
oxide. A continuous record was maintained by means of a Leeds and Northrup Speed-
omax H recorder. Full pen displacement was equivalent to 2.0 Langleys per minute,
while the speed of chart rotation was 50.8 mm (2.0 inches) per hour.
Special Observations
Radiosonde Releases In support of the airborne and ground-based plume and meteor-
ological measurements, free radiosondes were released twice daily during selected
experimental periods from Jimmy Stewart Airport. A 100-gram pilot balloon inflated
to about 1100 grams lift carried the 403-megacycle package aloft at a rate of about
300 meters/min (Figure 12). Transmissions of pressure, temperature, and humidity
were recorded on a 403-megacycle receiver using a manually-operated parabolic

antenna, while visual tracking by theodolite provided winds aloft data (rabal).
Both receiver and theodolite monitoring were terminated at 700 millibars.
Pilot Balloon Ascents Winds aloft were routinely measured during experiments at
the Conemaugh and Keystone Stations by double-theodolite observations of he1ium-
filled pilot balloons. Inflation of 30-gram sounding balloons to about 45 grams
lift provided an ascension rate of approximately 130 meters/minute through the
1500-meter observational layer. The use of a balloon inflated to a specific ascen-
sion rate permitted single-theodolite operation in the event one of the stations
lost the balloon in flight or experienced instrument or communication malfunction.
Observations were obtained by means of standard Warren-Knight Model No. 85
theodolites positioned at the end of baselines ranging in length from 283 to 552
meters. Several baselines were established at each generating station to ensure
adequate angular separation between simultaneous instrument readings and minimum
steam plume interference for a wide range of wind directions. Except when prema-
turely obscured by clouds or steam plumes, the balloons were tracked for 10 minutes,
with azimuth and elevation angles read at 30-second intervals. Communication be-
tween the two theodolite sites was maintained by E. F- Johnson Personal Messenger,
all-transistor, battery-powered transceivers.

OPERATING PROCEDURES FOR LAPPES EXPERIMENTS
Airborne measurements of the Conemaugh and Keystone plumes during 1971 were
obtained during two separate flight periods designated as the April 1971 and October
1971 series respectively. Unless prevented by plant shutdown, helicopter malfunc-
tion, or adverse weather, helicopter flights were conducted every day during these
periods. Adverse weather for this type of experiment included ceilings lower than
the plume, excessive ground fog, or strong turbulence caused by high winds; rain or
snow alone did not curtail the flights. To permit visual observation of the plume,
Pennsylvania Electric Company personnel reduced precipitator efficiency to allow
limited flyash release during periods in which experiments were conducted.

Usually two flights, each lasting about 150 minutes, were made on a series day.
The first commenced at dawn while the plume was normally isolated from the ground
by stable atmospheric layers near the surface. This flight consisted of one to
three cross sections preceded and followed by a 1000-meter vertical temperature
profile just upwind of the Conemaugh or Keystone stacks. The cross sections were
made at 4-, 10-, and 16-kilometer arcs downwind and consisted of successive cross-
wind flights through the plume at 60-meter vertical intervals; occasionally 30-meter
intervals were flown to better define the top and bottom edges. The first traverse
of each cross section was made approximately midway between top and bottom, with
successively higher traverses until the top was reached; then lower from the center
until the bottom was completed. In some cases this procedure was reversed so that
the lower half of the plume was flown first. By maintaining a constant forward
speed of 50 mph and by indicating surface reference points during plume passage,
the geometry of the plume may be reconstructed.
The second flight of a series day began simultaneously with the normal temper-
ature transition during which the layer in which the plume was imbedded was brought
to the ground. In addition to obtaining two or three more temperature profiles,
the helicopter was flown parallel and normal to the plume's longitudinal axis near
the surface to obtain the x and y dimensions of ground-level S02 concentrations.
This treetop-level flight was usually continued as long as fuel permitted unless
the ground-level concentrations originating from the plume terminated sooner. Occa-
sionally a third flight was executed during the afternoon to measure the effects
of a looping plume or the sustained downwash from a limited mixing layer regime.
If no ground-level concentrations occurred on a particular day, the second flight
was sometimes used to repeat one or more cross sections. All plume cross-section
and crosswind ground-level traverses were flown in the shape of arcs centered on
the Conemaugh or Keystone stacks. Helicopter positions during airborne sampling
were monitored and recorded by means of an on-board set of 7.5-minute-quadrangle
topographic maps (USGS, 1971).
11

-------
Helicopter measurements of ground-level concentrations were complemented with
a series of consecutive 3D-minute samples made by ten bubblers on the ground beneath
the plume. Placement of these portable units was dependent on helicopter location
of the plume aloft, and usually spanned the expected lateral projection to the
ground, of the plume aloft, ranging from near the plant to as far out as 28 kilo-
meters. On days of drastic plume shift, as determined from helicopter observation
prior to inversion breakup, the bubblers which had already been set out were not
analyzed when it was obvious that they were not influenced by the plume.

Prior to and after the daily airborne operations, radiosondes were released at
Jimmy Stewart Airport. Although detailed helicopter temperature measurements
revealed the stability through the plume's vertical extent, the radiosondes de-
tected such other pertinent features as subsidence inversions aloft. In addition,
these radiosonde releases will provide a means of comparing the climatology of
Pittsburgh with that of the immediate area. Between these two releases, double-
theodolite pibals were taken every 30 minutes at the Conemaugh or Keystone Station
to provide data on the wind directly affecting plume dispersion.
SELECTED PWME PHOTOGRAPHS
To assist in the physical interpretation of data contained in Part 2 of this
volume, four selected plume photographs are presented in Plates 1 through 4. Verti-
cal stability and wind data for these cases may be found in Tables 8, 9, and 10,
and dimensions of the plumes are depicted in Table 3. In all four photographs, a
visible plume was produced by means of intentional, limited flyash emission.

Plate 1 depicts the Conemaugh plume under very light wind conditions, with
unit 1 operating at full capacity (900 megawatts). The first cross section of the
morning revealed a plume width at 4 kilometers downwind of 129° or 9.0 kilometers.
Two hours later, at the time of this photograph, the plume had backed about 75° and
had narrowed to approximately one-half its former width. The limited vertical
extent of the S02 plume was caused by a stable layer aloft based about 700 meters
above stack base elevation and including a 0.8°C inversion between 735 and 950
meters. Subsequent helicopter flights detected ground-level S02 concentrations on
both sides of Laurel Ridge to 26 kilometers downwind, while portable bubblers pro-
vided coverage of the looping plume close to the generating station.
Dispersion of the Conemaugh plume across Laurel Ridge under near-neutral
stability and moderate-to-high wind speeds is shown in Plate 2, taken from 4 kilo-
meters downwind. Vertical mixing of the S02 plume was confined between the surface
and a stable layer aloft based about 1050 meters above stack base elevation. This
restriction on vertical dispersion was responsible for the fairly high ground-level
S02 concentrations measured by the helicopter on both sides of Laurel Ridge out to
12

-------
16 kilometers. When this photograph was taken. unit 2 at the Conemaugh Station was
operating near 83 percent of rated capacity.

Plate 3 illustrates the behavior of the Conemaugh plume while crossing the
Conemaugh Gorge under moderate wind. stable conditions. The photograph is oriented
so that the viewer is looking NNW. parallel with the gorge; the location of the peak
at upper left is 100°/7.5 kilometers from the Conemaugh stacks. The subsidence of
the S02 plume as it crosses the gorge after traversing Laurel Ridge dramatizes the
lee wave effect described in Part 1 under Topography and General Climatology. On
four separate occasions during the April 1971 series. the stable Conemaugh plume
was discovered to be intercepting distant ridges and flowing smoothly down the lee
side for 1 or 2 kilometers before rising again. On the day depicted in Plate 3.
the bottom of the 10 kilometer cross section was at the surface in the lee of Laurel
Ridge although the S02 concentrations were not as high as in the four above-mentioned
cases. At the time of the photograph. units 1 and 2 of the Conemaugh Station were
operating at 100 and 60 percent capacity respectively.
Plate 4 presents the Conemaugh plume from a vantage point about 10 kilometers
downwind. The plume. emitted from unit 2 operating at 89 percent of rated capacity.
is contained within a surface-based stable layer which extends beyond 1250 meters
above stack base elevation. This limited vertical extent combined with extreme
width (15.2 kilometers at 10 kilometers downwind) are characteristic of a fanning
plume; the horizontal dispersion in this case is further enhanced by light air flow
accompanied by oscillating directions. Four hours after this photograph was taken.
the plume had narrowed to 5.2 kilometers at 10 kilometers downwind. about one-third
its original width. Interestingly. the centerline remained in exactly the same
location; the plume had narrowed 28° and 29° on the right and left sides respec-
tively. Subsequent helicopter flights revealed high ground-level S02 concentrations
out to 34 kilometers during inversion breakup and out to 38 kilometers under a
limited mixing layer which persisted through the entire day.
CONTRACT PARTICIPATION IN LAPPES PROJECT
In addition to observations by EPA personnel. one contractor. Brookhaven
National Laboratory. participated in the LAP PES Project during 1971. During May.
October. and November 1971. Brookhaven personnel used a fixed-wing aircraft to
procure measurements pertaining to plume geometry and plume chemistry. By means
of an on-board densitometer using right-angle scattering with maximum sensitivity
at 0.6 microns. flyash particles in the 0.01- to 10-micron diameter range were
detected during successive crosswind flights downwind. thus providing a means of
defining plume geometry. In support of efforts to determine S02 reactions in the
plume aloft. controlled amounts of sulfur hexaflouride (SF6) were released into
the stack effluent. Evacuated flasks fitted with critical orifices were used for
11

-------
airborne collection. In order to obtain crosswind integrated values of SF6. one
continuous sample was obtained during each horizontal plume traverse. Subsequent
gas chromatograph analyses of the samples will provide data with which simultaneous
airborne S02 measurements can be compared and chemical reactions determined.

PART 2 - DATA TABULATIONS
INTRODUCTION
Part 2 presents in tabulated form the specialized air quality and meteorolog-
ical measurements as well as the plant operational data collected during two 1971
LAP PES series. Supplementary data that may assist in analyzing plume dispersion
are also included. These consist of surface meteorological and S02 measurements
obtained at Jimmy Stewart Airport and surface and 500-millibar charts for each
series day. An introduction to each set of tables describes the data and format
and gives other pertinent information.
The specialized air quality and meteorological measurements and plant opera-
tional data contained in Part 2 of this volume were collected during the following
periods:
April 1971 LAPPES Series
October 1971 LAPPES Series
21 April - 20 May 1971
18 October 17 November 1971
Supplementary data are included in Tables

All data are presented in metric units because the adoption of a single consis-
tent set of units allows more direct utilization of the data. This required con-
version of the following measurements: Aerovane wind speed, surface temperature
and precipitation, and all plant operational data. In performing these conversions,
care was exercised that neither a sacrifice nor an implied gain of accuracy was
effected.
Both polar and rectangular coordinate systems are utilized in this data
summary. With the Conemaugh or Keystone stacks as origin, the polar coordinates
locate specific points such as cross section reference points and bubbler sites.
On the other hand, right-hand rectangular coordinates are primarily used to indi-
cate directions and have no fixed origin. The rectangular system is oriented so
that plus x points downwind, and plus y indicates a counterclockwise direction
around the source.

DAIL Y EXPERIMENT SUMMARY
An experiment summary page is presented in Table 1 for each day during 1971
on which flights were made by the LAPPES helicopter or on which data were collected
by Brookhaven National Laboratory. Although hourly, plant-operational data are
listed in Table 12, the headings in the experiment summary identify the generating
station being sampled and designate the units in operation.
The summary sheets also enumerate the types of air quality and meteorological
measurements collected each day by LAPPES personnel. Although data from Brook-
haven's activities are not included in this volume, their participation is noted on
specific days. Also included is a commentary in which deviations from normal exper-
iment procedures are explained and items of relevant information are presented.
During both 1971 series, the Conemaugh plume occasionally traversed Chestnut Ridge
or laurel Ridge; this fact is mentioned in the commentary on appropriate days to
alert the reader that surface elevations under the plume were considerably higher
than stack base elevation.
The final section of each daily experiment summary consists of a brief descrip-
tion of the existing synoptic situation and the 0700 EST surface and SOO-millibar
charts from the Daily Weather Map (NOAA, 1971). The plume wind included in the
synoptic description is intended only to furnish a general indication of plume
direction and speed; complete wind profiles are presented in Tables 9 and 10 of this
volume.

High S02 background aloft and at surface. Very wide plume. Only 4 and 10 km cross sections attempted. Tops of both
incomplete because of low clouds; bottoms were at the surface. Few moderate wind, neutral GLC measured by helicopter
out to 16 km. Ground-level flights discontinued because of strong low-level turbulence and restricted visibility.
Bubblers were not set out. AutoAnalyzer at airport office measured high background GLC during morning. No afternoon
radiosonde released. Plume heading across Laurel Ridge.
Synoptic Situation

Regional - Cold front from New Jersey through Pittsburgh to western Illinois; N-S ridge from Hudson Bay to Florida
Gulf coast. Surface wind light northwesterly. Eastern U.S. under trailing edge of long-wave 500-mb trough; NW-SE
ridge over central U.S. Wind at 500 mb WNW 35 mps.
Local - Sunrise broken low clouds with fog and haze. Near-neutral to 995 meters. Plume wind W 6 mps. 1030 AM scat-
tered low clouds with haze. Inversion layers 590-700 and 1050-1100 meters; lapse below, between, and above to 1250
meters. Plume wind W 5 mps.

Helicopter takeoff delayed by fog. Three cross sections completed; bottom of 16 km cross section was at the surface.
Nearly all zero GLC measured by helicopter during morning. Ground-level flights discontinued and bubblers were not
set out because plume began to diffuse upward into overcast.
Synoptic Situation

Regional - Weak N-S ridge over eastern third U.S.; cold front from western Illinois through Maryland coast. Tropical
storm Laura over western Cuba. Surface wind light northwesterly. 500-mb high along Gulf coast with ridge northwest-
ward through Minnesota; secondary NE-SW ridge over Quebec. Wind at 500 mb NNW 30 mps.
Local - 9 AM low overcast with fog. Stable layer 100-500 meters; near-neutral below and above to 1070 meters. Plume
wind NNW 7 mps. 1230 PM low overcast. Slight inversion 550-565 meters; near-neutral below and above to 950 meters.
Plume wind NW 3 mps.

Commentary

Extremely wide plume. During first flight, extremely wide 10 km cross section completed; bottom was at the surface.
During second flight, 4 and 10 km cross sections completed; plume had narrowed considerably. Very high S02 concen-
trations in 4 km cross section. S02 from Seward plume included in GLC measurements near Conemaugh during early
morning and within 10 km during remainder of sampling period. Excellent coverage of inversion breakup GLC and limited
mixing layer GLC by helicopter out to 38 km during entire day; partial coverage by bubblers. Release of pilot bal-
loons delayed by dense fog. Area under air stagnation advisory.
Synoptic Situation

Regional - Ridge from eastern Quebec through Virginia to central Gulf coast; low over northern Wisconsin.
storm Laura southwest of Cuba. Surface wind calm. NE-SW 500-mb ridge from Gulf coast through Labrador.

SURFACE WEATHER AND S02 OBSERVATIONS AT JIMMY STEWART AIRPORT
Table 2 presents hourly meteorological and S02 measurements obtained at Jimmy
Stewart Airport for each day during 1971 on which flights were made by the LAPPES
helicopter or on which data were collected by Brookhaven National Laboratory.
Although experimental activities lasted less than 12 hours in most instances, values
for the entire 24 hours are included. Daily resultant winds, precipitation totals,
average and peak S02 concentrations, and total radiation are also presented.

For the majority of days, S02 concentrations are not available for a few hours
during the afternoon. This loss of data occurred while the Technicon AutoAnalyzer
was switched from on-stream monitoring to bubbler analysis.
In relating the surface meteorological measurements obtained at the airport
to plume dispersion at the Conemaugh Generating Station, the topographical effect
of Laurel Ridge, mentioned in Part 1 under Topography and General Climatology, must
be considered. Airport measurements of temperature, relative humidity, precipi-
tation, and total radiation will not be representative of conditions existing at
Conemaugh under the mechanically-induced cloud cover. Similarly. surface wind
directions and speeds in the proximity of Laurel Ridge may not be the same as those
measured at the airport.

PLUME CROSS SECTIONS
Cross sections of the Conemaugh and Keystone plumes obtained by the LAPPE5
helicopter are presented in Table 3. The orientation is such that the reader is
looking downwind with the plume top to his right. The height of each traverse
above the source generating station's stack base elevation is indicated over the
particular column of data with increasing altitude from left to right. The relative
order in which the traverses were flown is shown at the base of each column.
The plume can be physically located by means of radial directions listed in
the second column for each data point. These were determined by computing clock-
wise and/or counterclockwise from the given reference point in increments based on
the arc distance of the particular cross section. For the 4-, 10-, and 16-kilometer
cross sections, the radial increments between each data point are 1.92°,0.96°,
and 0.48°, respectively. Because of missing coordinates, the reference point for
cross section 408 was arbitrarily set at 360°; actual plume position may be derived
from related measurements.
The first column of each cross section lists the cumulative distance across
the plume beginning with zero at the left edge looking downwind. The corresponding
502 concentrations in pphm by volume are instantaneous readings taken at 6-second
intervals; this corresponds to a crosswind distance increment of 134.1 meters
(50 mph). The peak concentration in each traverse is shown at the bottom with the
data point nearest the peak's location indicated by an asterisk in the column
above. All instantaneous and peak 502 concentrations are net plume values, i.e.,
the ambient 502 and C02 backgrounds have been subtracted.
When the data are presented in this manner, the horizontal distance across
the plume is scaled correctly whereas the vertical is not. To achieve a true
physical reproduction of the plume, the distance between the columns would have
to be scaled according to the respective traverse heights. Although completely
zero traverses are shown as terminating at the plume edge, these flights were
normally extended well beyond to confirm the absence of 502. Finally. crosswind
and vertical integrated concentrations are listed at the bottom and side of each
cross section.
where
Crosswind integrated concentrations (CIC) in grams per square meter for each
plume traverse were calculated as follows:

CICj = 2.67 x 10-6 x f Xij dYi

2.67 x 10-6 = conversion factor from ppb to grams/m3 based on a mean temper-
ature aloft of 4°C and a mean altitude of 425 meters M5L.
Xij = 502 concentration in ppb of the i-th data point in the j-th traverse.
dYi = cross-plume interval at which readings were made (134.1 meters).

equation:
concentrations (VIC) in grams per square meter for each
from the properly aligned traverses by means of this
VICi = 2.67 x 10-6 x ! Xij dZj

2.67 x 10-6 = conversion factor defined above.
Xij S02 concentration in ppb of the i-th data point in the j-th traverse.
dZj = one-half the difference between the next higher and the next lower
pass for interior traverses. For the highest (lowest) traverse,
dZj is the height difference between the traverse and the next
lower (higher).
where
The crosswind and vertical integrated concentrations were computed on the
basis of ppb S02 during cross-section reduction and may differ slightly from the
result obtained by using the S02 values rounded to pphm, as presented in Table 3.

GROUND-LEVEL S02 CONCENTRATIONS - HELICOPTER
Table 4 presents the peak ground-level S02 concentrations measured during
lengthwise flights under the plume. Each value is the maximum concentration in
an interval of one kilometer, centered on the designated kilometer. The individual
flights are identified by beginning and ending times and locations, with corre-
sponding S02 concentrations arranged under their respective distances downwind.

Table 5 summarizes the ground-level S02 concentrations obtained during cross-
wind flights under the plume. Although each arc distance from the plant is speci-
fied, most of the traverses were executed at distances corresponding to the cross
sections. Each flight is identified by beginning and ending times and a rectan-
gular origin near the plume center. The data are then listed in the plus y and
negative y directions with the concentration at the origin repeated for both seg-
ments; actual flights, however, were continuous across the plume.
The values shown in Table 5 are instantaneous readings reduced at 6-second
intervals. This corresponds to a crosswind distance increment of 134.1 meters.
Occasionally, only plus y or negative y segments are presented; this occurs if
the origin was established outside the plume or if restrictions prevented a complete
crosswind flight. Incomplete flights are recognizable by the absence of a zero at
the end of one or both segments.

In Tables 4 and 5, the S02 concentrations are net plume values obtained by
subtracting the ambient S02 and C02 background. Completely zero flights are
included in both tables to indicate the absence of ground-level S02 concentrations
at that particular time and location.

GROUND-LEVEL S02 CONCENTRATIONS - BUBBLERS
The ground-level S02 concentrations measured by portable bubblers are summa-
rized in Table 7. Data are arranged by series day with each bubbler heading con-
taining its identification, coordinates, and height above or below the source
generating station's stack-base elevation. Also included in the heading is a
three-letter code describing the terrain, vegetation, and ground cover in the vicin-
ity of the sampling site. Descriptions corresponding to this code are presented in
Table 6.
Due to occasional bubbler malfunctions, some sampling periods may be shorter
or longer than 30 minutes; this was considered in the reduction, and actual sampling
times are listed as such. Caution should be exercised in interpreting the bubbler
concentrations since no compensation was made for background S02 levels.

HELICOPTER TEMPERATURE PROFILES
Table 8 lists the helicopter temperature profiles obtained during spiral
ascents just upwind of the Conemaugh and Keystone Stations. Dry-bulb and wet-bulb
temperatures are listed for 50-meter intervals above the applicable stack base
elevation; additional levels such as bases and tops of inversions are also listed.
Wet-bulb values are occasionally missing because the sensor froze.

On most profiles, surface dry-bulb and wet-bulb values are included. These
temperatures were measured within 1 meter of the surface during 10-mps or greater
forward speeds so that no downwash interfered with the readings. To allow for
changing pressure patterns during an experiment, the helicopter landed before each
profile so the indicated surface height from the pressure transducer could be
recorded. A flight time of approximately 5 to 7 minutes was required to complete
a 1000-meter profile.
During the 1971 series, three helicopter temperature profiles were origi-
nated about 4 kilometers north of the Conemaugh Generating Station because of
ground fog in the valley surrounding the station. The origin for these profiles
(578, 658, and 659) is indicated in the subsequent legend. Also included in the
legend is the origin for profile 636 which was executed 16 kilometers north of
Conemaugh because of low fuel supply.

PILOT BALLOON MEASUREMENTS
Pilot balloon measurements of winds aloft were made at the Conemaugh or
Keystone Station during all LAPPES experiments. Depending on prevailing meteoro-
logical conditions and the length of flights, as few as three and as many as ten
ascensions per series day were made, usually at 30-minute intervals. Most of the
pilot balloons were tracked using the double-theodolite technique; when fog pre-
vented visibility between sites, single-theodolite releases were made. Similarly,
when one observer lost the balloon prematurely, the computer calculated the remain.
ing portion of the run based on observations from a single theodolite, using the
previously determined double-theodolite ascension rate.
Table 9 lists the winds aloft in increments of 50 meters above Conemaugh or
Keystone stack-base elevation, up to a maximum height of 1500 meters. The wind
speed and direction for each level were obtained from the original data by inter-
polating between the 30-second readings.

RADIOSONDE MEASUREMENTS
Radiosonde observations taken at Jimmy Stewart Airport are presented in Table
10. On most experiment days, two releases were effected, one prior to and another
following the airborne activities. In addition, a single early-morning radiosonde
was occasionally released on days during which the weather proved too restrictive
for flying; these observations are also included in this table.
The pressure, temperature, dewpoint, and height above MSL of each mandatory
and significant level up to and including 700 millibars are given for each radio-
sonde observation in Table 10. The accompanying rabal wind speeds and directions
are listed for fixed heights, i.e., surface, 150 and 300 meters above surface, and
500, 1000, 1500, 2000, 2500, and 3000 meters MSL. Elevation of the release site is
428 meters MSL.

POWER PLANT OPERATIONAL PARAMETERS
Analyses of the Conemaugh and Keystone coal supplies are presented in Table 11
Although various mines supplied coal to each of the generating stations, daily
weighted means were calculated for each source and averaged over all experiment
days to obtain a single coal analysis for each station per series. Parameters
include moisture, volatile matter, fixed carbon, ash, sulfur, and heat value. The
sulfur content is a close approximation to the "as burned" basis with allowance
made for rejection of sulfur-containing pyrites. The heat value of the coal is
presented in English as well as metric units because of common usage.

Table 12 contains the hourly operational
Stations. Included are values of plant load,
;ty, temperature difference at stack tQ~, S02
data of the Conemaugh and Keystone
stack-gas exit temperature and veloc-
emission, and heat emission. The
240

-------
nominal period of record extends up to 2 hours before and 1 hour after helicopter
or bubbler S02 measurements on each series day. When both stacks of one station
were emitting. a separate listing is included for each.

The plant load was obtained from the station records and includes total elec-
trical output generated during each hour. Temperature difference at stack top is
the difference between stack exit temperature and the 300-meter SBE ambient temper-
ature at the Conemaugh Station. or the 250-meter SBE ambient temperature at the
Keystone Station. as determined from the helicopter profiles. The stack exit
temperature was not monitored; instead. corrections of 16.7°C (30°F) at Conemaugh
and 13.9°C (25°F) at Keystone were subtracted from the effluent temperatures leaving
the air heaters.
The equations presented below permit calculation of the remaining three param-
eters (Carpenter and Blackwell. 1969). The units of the formulas are British be-
cause all plant data were so supplied; after calculations were performed, conver-
sion was made to metric units.
The hourly stack-gas exit velocity in feet per second was calculated from the
following equation:
v - Tc [H20(359) + C02(359) + N2(359) + S02p59~ + Ae(359)] ts + 460
- 3600 As (-rB) (~) (~) 64 (:29) 32 + 460
where Tc = hourly coal consumption in pounds per hour per unit.
As = stack exit area = 581.42 square feet for Conemaugh and Keystone.
ts = hourly gas temperature leaving stack in degrees Fahrenheit.
32 = standard temperature in degrees Fahrenheit.
460 = conversion to Rankine temperature scale.
3600 seconds per hour.
H20. C02, N2. and 502 - series average in pounds per pound of coal as pro-
ducts of combustion.
Ae = series average excess air in pounds per pound of coal required for
combustion.
Denominators in parentheses are molecular weights of respective gaseous
constituents in whole grams per mole.
359 conversion factor to British units calculated as follows:
22.414 l~ters/mole 453 59 /lb = 359
28.317 1,ters/ftJ x . g
Hourly 502 emission from each unit in tons per hour was calculated by means of
this formula:
SO = Tc x %S x 2

Tc = hourly coal consumption in pounds per hour per unit.
%S = decimal equivalent of series average percent sulfur in fuel.
2 - mass of S02 per unit mass of sulfur.
2000 = pounds per ton.

The final parameter, stack heat emission in British thermal units per second,
was computed from the following equation:

series average heat value of fuel in Btu's per pound.
hourly gas temperature leaving stack in degrees Fahrenheit.
hourly gas temperature leaving air heaters in degrees Fahrenheit.
hourly ambient temperature at stack top in degrees Fahrenheit.
Although hourly coal consumption is not included in this volume, it can be
approximated for the Conemaugh Station using the ratios of 0.734 and 0.746 pounds
of coal per kilowatt hour generated in units 1 and 2 respectively. This amounts
to 3.87 x 10-4 and 3.93 x 10-4 grams per calorie for units 1 and 2. The corre-
sponding ratio for unit 1 at the Keystone Station is 0.757 pounds of coal per
kilowatt hour or 3.99 x 10-4 grams per calorie.

PART 3 - LAPPES PROJECT SUMMARY
INTRODUCTION
Part 3 presents a summary of activities performed during the five-year LAPPES
Project in western Pennsylvania. The three major divisions of effort consisted uf:
(1) procurement by LAPPES personnel of airborne and ground-based S02 measurements
of tall stack plumes, supported by extensive meteorological observations; (2) con-
tract and voluntary participation by private research organizations; (3) evaluation
of effects of sulfur compounds and other effluents from a large generating station
complex on vegetation in the adjoining region.
The specialized air quality and meteorological measurements by LAPPES personnel
were obtained during the following eleven sampling periods:
October 1967 LAPPES series
March 1968 LAPPES series
May 1968 LAPPES series
July 1968 LAPPES series
October 1968 LAPPES series
April 1969 LAPPES series

Most of the participation by private research organizations in the Large Power
Plant Effluent Study was performed under contract to the Division of Meteorology,
Environmental Protection Agency, or its predecessor, the National Air Pollution
Control Administration. In Part 3, activities of the contractors and voluntary
participants are described, accompanied by individual bibliographies which summarize
publications and presentations referring to their participation in the LAPPES
Project.
The third major division of LAPPES, the vegetative study, lasted from 1967
through 1971. Descriptions of the various types of air quality and agricultural
measurements collected as part of the vegetative study are also included in Part 3.

LAPPES SERIES SUMMARY
Table 13 contains an individual summary for each of the eleven series conducted
during the LAPPES Project. Included in each series summary are designations of the
source generating station and unit(s) in operation while plume sampling was in pro-
gress. In addition, daily totals are presented of the various types of S02 and
meteorological measurements which were obtained.

Identification of the source generating station is included only for days on
which plume S02 measurements were procured by LAPPES personnel. Additional dates
are listed in Table 13 for which daily totals of helicopter temperature profiles,
pilot balloons, and/or radiosondes are presented; these meteorological data were
obtained by LAPPES personnel either in support of participating contractor activi-
ties or on days when the weather later proved too restrictive. for plume sampling.

CONTRACT AND VOLUNTARY PARTICIPATION IN LAPPES PROJECT
During the five-year LAPPES Project, contract and voluntary participation by
private research organizations played a significant role. The services of six
contractors were engaged by NAPCA and EPA to collect and analyze data pertaining
to the dispersion, chemistry. and washout of the S02 and/or cooling tower plumes.
Two voluntary participants, while conducting their own research, also provided data
of interest. In the following section, activities of the contractors and voluntary
participants are described, accompanied by individual bibliographies which summarize
publications and presentations referring to their participation in the LAP PES Pro-
ject.
These descriptions are intended to be procedural only; therefore, no attempt is
made to summarize data or results. Such information may be obtained by referring to
the contractors' final reports or related publications.
Stanford Research Institute
During the May and October 1968 LAPPES series, a team of scientists from
Stanford Research Institute (SRI) of Menlo Park, California, used a mobile SRI
Mark V neodymium lidar (laser radar) to measure plume rise, plume geometry, and
plume particulate concentration distributions at various distances from the Keystone
stacks. During the April 1970 series, SRI personnel procured similar measurements
of the Homer City plume by means of a mobile SRI-NAPCA Mark VIII ruby lidar. SRI
participation in all three series was performed under contract with NAPCA.

The lidar cross sections were obtained by means of a vertical scanning tech-
nique with elevation angle increments of 0.3° to 10.0°, depending upon the vertical
extent of the plume. Such scans were accomplished by positioning the lidar van to
the side of the plume and scanning perpendicular to its mean centerline and at 45°
on either side of the perpendicular, thus obtaining three cross sections from a
single location. A complete vertical scan of 20 to 30 lidar shots required about
2 to 5 minutes to complete" and a set of three cross sections was obtained in 10 to
15 minutes.
The lidar was also used to check plume
at fixed distances downwind and at specific
apart) during an entire day, beginning with
with the onset of evening stability.

The lidar data were recorded on both a video magnetic disk recorder and on an
oscilloscope equipped with a 35-millimeter recording camera. A second oscilloscope
used in conjunction with the disk recorder permitted visual monitoring of each lidar
shot. The 35-millimeter film records were used for manual analyses while computer
analyses employed the magnetic disk records.

Sign X Laboratories, Incorporated
Under contract to NAPCA, a meteorologist from Sign X Laboratories, Incorporated,
of Essex, Connecticut, used an instrumented Bell Model 47G helicopter to measure
plume rise at the Keystone Generating Station during the May and October 1968 LAPPES
series. Instrumentation used in the Sign X helicopter was similar to that in the
LAPPES helicopter with one exception: in addition to continuous recordings of sul-
fur dioxide, pressure-height, temperature, and wet-bulb depression, a space charge
derivative unit was operated to detect charged particulates in the plume. This
enabled simultaneous estimates of plume dimensions during each traverse of both
particulates and S02'

The flight pattern used to define plume rise included both slanting and hori-
zontal traverses through the plume. The slanting traverses began about 6 to 8
kilometers downwind and consisted of a series of climbing and descending passes
274

-------
through the densest part of the plume, toward the stacks. The horizontal traveY~es,
constituting a cross section, were made at fixed distances downwind. Beginning at
the top of the plume, successive traverses at 60-meter intervals were made until the
bottom was reached; occasionally, this was followed by a series of ascending hori-
zontal passes through the plume in between the levels of descending traverses.

Supporting meteorological data for these experiments included helicopter temper-
ature profiles by the Sign X helicopter at the Keystone Station. LAPPES personnel
provided double-theodolite pilot balloons at Keystone and radiosondes and surface
observations at Jimmy Stewart Airport.
The following bibliography summarizes Sign X publications and presentations
pertaining to their participation in the LAPPES Project.

Meteorology Research, Incorporated
Also under contract to NAPCA, personnel from Meteorology Research, Incorporated
(MRI), of Altadena, California, flew an instrumented Aztec C to obtain particle
size distribution and turbulence measurements in the Keystone plume during the
October 1968 LAPPES series.
Airborne determination of the flyash concentration and size distribution were
procured for comparison with concurrent lidar observations being conducted by SRI.
Using an MRI moving slide impactor and continuous particle collector, measurements
were made of flyash particle size in both the "dirty" and "clean" plumes at Keystone,
dirty referring to 50 percent passage of flyash out the stack and clean denoting all
precipitators in operation. Airborne measurements with a universal turbulence indi-
cator system were made under various meteorological conditions in the Keystone plume
and in the vicinity of the Homer City and Conemaugh Generating Stations, then under
construction.
The flight pattern used for measurements of both parameters at Keystone con-
sisted of lengthwise flights in the plume from 16 kilometers downwind to the stacks
and of successive horizontal traverses through the plume at 3.2, 8.0, and 16.0
kilometers downwind. Spiral soundings at the plant and 16 kilometers downwind were
executed to provide meteorological conditions and background particle samples.

Besides the aircraft observation, MRI personnel operated a ground-based camera
sequentially photographing the Keystone plume from a position perpendicular to its
275

-------
centerline. The photographs were obtained to provide plots of plume sizes and posi-
tion for comparison with theoretical predictions of plume rise and for comparison of
the usefulness of the photographic technique with the lidar method.

In addition to the temperature profiles by the MRI Aztec, supporting meteoro-
logical data provided by LAPPES personnel included helicopter temperature profiles
and double-theodolite pilot balloons at the Keystone Station and radiosondes and
surface observations at Jimmy Stewart Airport.

Illinois Institute of Technology Research Institute
Personnel from the Illinois Institute of Technology Research Institute (IITRI)
of Chicago, Illinois, conducted a two-phase study of cooling tower plumes at the
Keystone Generating Station during 1969. The purpose of their study was to describe
and evaluate potential effects on the local environment, climate, and nearby gener-
ating station smoke plumes that resulted from cooling tower emissions of water vapor
and heat. IITRI participation was performed under contract with NAPCA.

During September 1969, a ground-based survey was executed in the vicinity of
Keystone to evaluate the heat and water balances through the cooling towers. The
airborne phase of IITRI's study was conducted in November and December 1969 and
involved the use of an instrumented Bell Model 47J2 helicopter. Airborne measure-
ments permitted the determination of ambient and plume temperature and humidity
profiles; background and plume sulfur dioxide concentrations by means of a Davis
S02 monitor; and size and acidity of plume droplet samples collected by Casella
cascade impactors.
The helicopter flight pattern used to collect the data was initiated by a
vertical ascent upwind of the Keystone Station to determine the temperature-humidity
profile and background S02 concentrations. This was followed by successive hori-
zo~tal traverses through the cooling tower plume at various distances downwind of
the visible portion. A low-level flight lengthwise under the plume toward the
towers completed the standard flight pattern. Plume droplet samples were collected
along the edges of the visible plume.

In addition to the temperature profiles by the IITRI helicopter, supporting
meteorological data for these experiments provided by LAPPES personnel consisted
of surface observations at Jimmy Stewart Airport. Additional surface and upper
air wind data and precipitation records were utilized from stations within an
aD-kilometer radius of the Keystone Station.

Battelle Memorial Institute, Pacific Northwest Laboratory
Under contract to NAPCA, a team of scientists from Battelle Memorial Institute,
Pacific Northwest Laboratory, of Richland, Washington, collected and analyzed rain-
fall and snowfall samples under the Keystone plume during three periods, i.e.,
October-November 1969, February 1970, and April-May 1970. The purposes of the
field operations were to determine the scavenging efficiency by natural precipita-
tion of airborne contaminants and to identify the chemical composition of surface-
collected precipitation.
Precipitation samples were obtained by arranging collectors in three arcs under
the plume at approximate distances of 2.0, 4.0, and 6.5 kilometers downwind. To
inhibit the sulfur dioxide loss or chemical reaction, some collectors contained
tetrachloromercurate solution. Immediate analyses of the samples in a field labo-
ratory yielded measurements of acidity, sulfur dioxide, sulfates, nitrates, and
nitrites. Supplementary ground-based measurements obtained during the experiments
included rainfall rate determined by weighing-bucket rain gages; raindrop size and
electric charge spectra by means of spectrometers; adsorption of S02 on flyash col-
lected with an electrostatic precipitator; ground-level sulfates determined from
high-volume air samplers; and photographs of snowflake characteristics.

During the first two sampling periods, an instrumented Cessna 172 was used to
provide background and plume measurements of temperature, humidity. and sulfur

conditions in which sampling was performed, the aircraft was used only intermit-
tently. The standard flight pattern consisted of successive horizontal traverses
through the plume at fixed distances downwind and at vertical intervals of 30 or 60
meters.
Supporting meteorological data obtained by Battelle personnel included single-
and double-theodolite pilot balloons and vertical profiles of temperature and
humidity at the Keystone Station as well as the previously mentioned measurements
pertaining to rate and nature of rainfall and snowfall. LAPPES personnel provided
surface observations at Jimmy Stewart Airport.

Research Laboratories, French Meteorological Services
A voluntary participant in the LAPPES Project during 1970 and 1971 was
Mr. L. Facy, Director of the Research Laboratories of the French Meteorological
Services. Using water tunnel facilities located in his Paris laboratory, Mr. Facy
initiated a model study of Conemaugh plume dispersion.

His first approach was the construction of a model to duplicate the moderate-
to-high wind, neutral-stability case during which the Conemaugh plume traverses
Laurel Ridge and Conemaugh Gorge, with emphasis placed on possible channelling
through the gorge. If successful, the program's scope would be broadened to study
the plume's behavior under gravity-wave action in stably stratified layers over
Laurel Ridge. The objectives of both models were to determine the possibility of
278

-------
"fumigating" the lee slopes of Laurel Ridge and the city of Johnstown during epi-
sodes of northwest winds, and if it did occur, to locate the areas of maximum
ground-level S02 concentrations.

During the October 1970 series, LAPPES personnel cooperated in this venture by
procuring additional S02 and meteorological data. Besides the helicopter temper-
ature profiles flown at the Conemaugh Station, additional profiles were executed
over Johnstown to enable a comparison of stability aloft as affected by the ridge.
Other specialized measurements included the placement of portable bubblers on both
sides of Laurel Ridge and in the Conemaugh Gorge during periods of northwest winds.
Additional supporting meteorological data supplied to Mr. Facy included double-
theodolite pilot balloons at the Conemaugh Station and radiosondes and surface ob-
servations at Jimmy Stewart Airport.
The following bibliography summarizes Mr. Facy's publications pertaining to his
participation in the LAPPES Project.

Brookhaven National Laboratory
Participation in the LAP PES Project by Brookhaven National Laboratory of Long
Island, New York, was of both a voluntary and contract nature. During 1968 and
1969, Brookhaven personnel used a fixed-wing aircraft to collect Keystone plume
samples for isotopic analysis. The S32/S34 ratios in these samples were compared to
the corresponding ratio in the supply coal in an attempt to establish a correlation.
In addition to collecting plume samples, Brookhaven scientists performed an aerial
infrared mapping of vegetation in the local area during 1968.

Under contract to EPA, Brookhaven participated in the LAPPES Project during
October and December 1970 and May, October, and November 1971. During these periods,
Brookhaven personnel used a fixed-wing aircraft to procure airborne measurements
pertaining to plume geometry and plume chemistry.
By means of an on-board densitometer using right-angle scattering with maximum
sensitivity at 0.6 microns, flyash particles in the 0.01 to 10 micron diameter
range were detected during successive crosswind flights downwind, thus providing a
means of defining plume geometry. In support of efforts to determine S02 reactions
in the plume aloft, controlled amounts of sulfur hexaflouride (SF6) were released
into the stack effluent. Evacuated flasks fitted with critical orifices were used
for airborne collection. In order to obtain crosswind integrated values of SF6,
279

-------
one continuous sample was obtained during each horizontal plume traverse. Subse-
quent gas chromatograph analyses of the samples will provide data with which simul-

While the airborne operations were in progress, ground-level SF6 concentrations
and densitometer background information were being simultaneously collected. In
addition to the vertical temperature profiles and pilot balloon data obtained by
Brookhaven, supporting meteorological data provided by LAPPES personnel included
helicopter temperature profiles and pilot balloons at the Keystone Station and
radiosondes and surface observations at Jimmy Stewart Airport.

LAPPES VEGETATIVE STUDY
The third major division of LAPPES, the vegetative study, was operational from
1967 through 1971. The proposed ten-year investigation was intended to evaluate
the effectiveness of tall stacks in preventing injurious effects by sulfur compounds
and other effluents on vegetation in the region surrounding the Keystone, Homer
City, and Conemaugh Generating Stations. This primary objective was to be accom-
plished by analysis of vegetation for acute and chronic injury and by measurements
of ground-level concentrations of sulfur dioxide (S02), nitrogen dioxide (N02),
oxidants (03), hydrocarbons, and aldehydes, supported by a comprehensive meteoro-
logical monitoring program. Because of funding and manpower priorities, however,
the study was prematurely terminated after only partial results were obtained.
The field project was
ing areas consisting of 15
located at distances of 8,
activated in 1967 with the establishment of 22 monitor-
Scotch pine and 7 white pine plots. These areas were
16, 32, 48, 64, and 80 kilometers in the prevailing
280

-------
downwind direction (northeast) of the line connecting the three generating stations.
Sulfation candles and plates were installed at these locations and leaf samples of
both deciduous vegetation and pine trees were collected for sulfate analysis.

A tobacco sensitivity program for determination of air pollution effects was
conducted during the summers of 1968 and 1969 at the same monitoring areas. By
visual observation of damaged leaf areas, moderate to severe foliage injury was
observed in both years as a result of oxidants and/or oxidant mixtures with other
pollutants.
The vegetative study was expanded in 1969 to include eight 4- to 6-acre major
research areas with similar soil, drainage, and slope characteristics. Six of these
sites were located northeast of the Homer City Generating Station at distances of
about 2,11,22,34, 50, and 66 kilometers. The remaining two areas were situated
between the generating stations at 8 and 11 kilometers northeast of the line tra-
versing the three stations. Within each area, irrigated and non-irrigated plots
were developed; irrigated plots were set up to determine effects under conditions
of maximum soil moisture. A random plot design was utilized for conifer and decid-
uous tree species planted in the eight areas. In addition, subplots were estab-
lished in each area for herbaceous crop species of commercial importance. Plans
for data analyses within the research areas included the determination of visible
injury and measurement of growth and yield effects.
To obtain correlation between research areas, air monitoring for oxidant, sul-
fur dioxide, and nitrogen oxides began during the 1969 growing season. Temperature,
humidity, solar radiation, and rainfall instrumentation were added in 1970. Wind
speed, wind direction, soil temperature, and soil moisture devices were also planned,
but were not implemented.

Although the project was never fully operable, vegetational injury from sulfur
dioxide and/or oxidants was observed on various tree and herbaceous species through-
out the study region. A final report of the vegetative study is being prepared and
will be available for additional information.

ACKNOWLEDGMENTS
As the Large Power Plant Effluent Study is terminated, specific mention
be made of the contributions and cooperative efforts of many individuals who
ensure the success of such a comprehensive project.

Permission for EPA to utilize data and facilities at the Keystone, Homer City,
and Conemaugh Generating Stations was granted by the following twelve electric
utility companies comprising ownership of the stations:

Atlantic City Electric Company
Baltimore Gas and Electric Company
Delmarva Power and Light Company
Jersey Central Power and Light Company
Metropolitan Edison Company
New York State Electric and Gas Corporation

Personnel of the Pennsylvania Electric Company, particularly W. Verrochi,
R. Conrad, D. Park, and D. Fyock, provided valuable assistance in the initial and
continued execution of LAPPES. The staffs of the Keystone, Homer City, and Cone-
maugh Stations cooperated in numerous ways, including but not limited to: (1) con-
ducting tours to acquaint EPA personnel with generating station operations; (2)
manipulating electrostatic precipitator efficiency to permit limited flyash release,
thus enabling visual plume tracking; (3) supplying nonroutine plant operational
data during sampling periods; (4) allowing unrestricted access to and publication of
station performance and operations data.
On-site EPA personnel, R. Soller, W. Kemp, E. Tillotson, and T. Therkelsen,
were instrumental in the collection and reduction of LAPPES data. Additional
assistance in the procurement of measurements was provided by several meteorological
technicians from the Division of Meteorology, EPA (formerly Air Resources Cincinnati
Laboratory, NAPCA). Computer manipulation of data was provided by W. Umfleet.
Marianne Proch typed the manuscripts for the four LAP PES data summaries.

In preparing and conducting the LAPPES experiments, the combined experience
of TVA personnel was drawn upon. Specifically, F. Gartrell, F. Thomas, S. Carpenter,
and J. Blackwell assisted in the initial planning of LAP PES and in furnishing
techniques to reduce plant operational data.

Professors P. Prince, M. Stapleton, F. Liegey, and S. Tackett of the Indiana
University of Pennsylvania provided logistical support in establishing the LAP PES
field office and on subsequent occasions.
The conduct of LAP PES was continuously monitored by an advisory committee
composed of J. Fuquay, D. Pack, R. McCormick, F. Gartrell, M. Smith, H. Panofsky,
and D. Lohman. This committee met twice yearly to review current progress and to
suggest future activities.

Finally, the personal advice and assistance offered to the Project Meteoro-
logist by R. McCormick, L. Niemeyer, and F. Pooler proved invaluable.
