1.0 INTRODUCTION
In recent studies of several source categories of chlorinated
organic compound emissionst the U.S. Environmental Protection Agency
(EPA) identified several sources that may pose high human health risks.
These compounds are ethylene dichloridet carbon tetrachloridet
chloroformt perchloroethylenet trichloroethylenet and methylene chloride.
This report examines (1) certain inputs used in dispersion modeling
and (2) the likelihood that locations immediately surrounding
facilities that emit the compounds identified above could be
habitable.
Radian confirmed the existing model inputs or provided corrected
information for each of the point sources of concern. The information
evaluated for the point sources is documented in the source summary
sheets. This information includes:
.
the latitude and longitude of the sourcet
the most appropriate STAR meteorological station for
the sourcet
a description of the topography and habitability of the
area of maximum modeled concentrations rfor each chemicalt
in the case of multiple pollutants from one source)t and
a description of the topography and population density
of the area within 50 kilometers of the source.
.
.
.
Section 2.0 is a summary of the results of the verification work.
Section 3.0 is a description of the verification methodology. Section
4.0 contains a list of the references used in verifying all the point
sources of concern in this project. The summary sheets containing the
source information described abovet photocopies of the maps containing
source locationst and concentration grid overlays for use with the
maps are included in the Appendices by source category. A list of the
sources of the current modeling information and a list of references
used to verify the latitudes and longitudes is also included in each
Appendix.
-------
2.0 RESULTS
A summary of the suggested changes in the modeling information is
presented in Table 1. Changes in the modeling inputs were suggested
for 14 of the 62 sources verified in this project. Changes in
latitude and longitude only were recommended for ten sources, changes
in the STAR site selection were recommended for two sources, and
changes in both latitude and longitude and STAR site selection were
recommended for two sources. Radian recommended that the dispersion
modeling be repeated, with the suggested changes, for the 14 sources
listed in Table 1. Sources for which differences in reported and
verified coordinates were different by more than 1.5 minutes were
highlighted. The reported coordinates are those that were being used
to model risk at the time that the source data were being verified.
The topographic analysis indicates that 38 of the sources
studied, or 61%, are located 'within 0.5 kilometers of a nonhabitable
area. In addition, the predicted maximum concentrations of pollutants
from six of the sources studied, or 10%, occur within 0.1 kilometers
of a nonhabitable area. Nonhabitable areas are usually bodies of water,
such as bays, rivers, streams, and settling and disposal ponds. A
review of the population density within 50 kilometers of each source
has shown that 13 of the sources studied, or 21%, are located in urban
areas. An urban area is one in which the population density is
greater than or equal to 200 persons per square kilometer. This is
the population density at which 50% of the area within 50 kilometers
of the source is indicated to be urban on the topographic map.

aThe verified latitude and longitude for these sources differs by less
than 1.5 minutes from the current coordinates. But because it was
estimated that habitability of the area of predicted maximum
concentration would change significantly if the verified coordinates
were used, it was recommended that the coordinates be changed.

- 3.0 VERIFICATION PROCEDURE
This section contains a summary of the procedure used to select
sources to be verified, verify source information, gather information
on population and topography, and determine the habitability of the
area of predicted maximum concentrations. The procedure for verifying
the coordinates of colocated sources is also described in this
section.
SelectinQ Sources to be Validated
For some pollutants or source categories, model inputs for all of
the source locations can be evaluated. However, the level of effort
for this project prohibited verifying all sources in a category
because there were too many locations. Higher risk sources were
selected from computer printouts of the Human Exposure Model
previously run by EPA that were provided to Radian. The sources to be
evaluated in this study include those resulting in a maximum
individual lifetime risk of caricer of 1 x 10-4 or greater (when the
maximum individual risks for all the pollutants emitted from a source
are summed). (This will likely provide an overestimate of the maximum
individual risk because different pollutants may have different points
of maximum concentrations.) Unless otherwise directed by the EPA
Technical Project Officer, Radian identified sources that (1) have an
aggregate risk of ten percent of the aggregate risk for that chemical
(across all sources categories) and (2) meet the 1 x 10-4 maximum
individual (combined chemical) risk cutoff.
Verifvina Latitude and Lonaitude
The locations of the sources were identified on U. S. Geological
Survey maps using the existing latitude and longitude information. If
the location indicated by the latitude and longitude did not appear to
be the location of the plant, the coordinates were evaluated using one
or all of the following sources of information. First, latitude and
longitude were obtained from the Section 114 responses, when available.
Second~ state agencies were asked to provide the latitude and
longitude supplied by the facility in state air permit applications.
Third,: summaries of the National Emission Data System (NEDS), when
-4-
-------
available, were examined for their latitude and longitude information.
Fourth, if the location of a facility was still uncertain, then the
plant address and latitude and longitude was obtained directly from
the plant personnel. The Technical Project Officer was notified when
plant personnel were contacted.
If the verified latitude and longitude of a facility differed from
the existing information by more than one and one-half minutes.
(approximately 2 kilometers), Radian recommended that the model inputs
be updated to reflect the verified coordinates. Radian also recommended
changing the latitude and longitude if habitability of the area of
predicted maximum concentrations was significantly different at the
current and the verified locations. Based upon sensitivity analyses
of the HEM, it was recommended that the dispersion modeling should be
repeated when changes in the verified latitude or longitude were
different by 1.5 minutes or more. [Note: 1 minute = 1.5 kilometers.]
The verified source location was marked on the photocopied map with a
large cross (+).
STAR Site Selection
The HEM uses meteorological data for air dispersion modeling near
a source. The HEM chooses meteorological data from the STAR
(STability ARray) site closest to the facility being modeled.
However, meteorological information from the STAR site nearest to the
facility may not provide the best basis for dispersion modeling of
that source. Wind patterns at the source location may differ
significantly from those at the nearest STAR site if the source is
located in complex terrain or near a coastal region. For sources
located in these topographically complex regions, further analysis of
the STAR site selected by the HEM is necessary to ensure that the
meteorological conditions at the STAR site selected are truly
representative of those at the facility.
The following is a description of the procedure followed by
Radian's staff meteorologist to evaluate the appropriateness of the
STAR site chosen by the HEM for each facility. The STAR sites
selected for each facility were obtained from the HEM printouts
provided by the Technical Project Officer.

A four-step procedure ' was used ,to verify that the HEM selected an
appropriate STAR site for each source. First, the location of the
STAR site was identified on a U. S. Geological Survey topographical
map. Second, the coordinates of nearby STAR site locations were
identified from STAR site selection maps in SAI's "Human Exposure to
Atmosp~eric Concentrations of Selected Chemicals, Volume 1.,,1
Third, the topography around the source was examined to identify
any significant features, such as river valleys, mountains, or coastal
areas that may affect wind flow near the source. The topography of the
area around the current STAR site was examined in the same way. If the
topography of the source location causes severe wind flow distortions
not found at the current STAR site, an alternate STAR site was
considered.
Fourth, the annual surface wind rose patterns in the area near the
source:were examined. Climatological wind rose patterns were obtained
from the U. S. Department of Commerce Climatic Atlas of the United
States;2 If wind rose patterns at the source location were significantly
different from those at the STAR site selected by the model, then the
wind rOse patterns at other nearby STAR sites were examined to
identify a more appropriate STAR site. The possible influence of
topography on wind flow at the STAR site was also considered.
Alternate STAR sites were selected from the STAR Tabulations
Master'Lists.3,4 Only STAR sites within 200 kilometers of the point
source'were considered as alternates. If an alternate STAR site was
suggested, Radian recommended that the dispersion modeling be repeated
with t~e new STAR site. The choice of STAR site has been found to
significantly affect the results of the dispersion modeling.
GatherinQ PODulation and GeoQraDhical Data
I
Population density was estimated using the latest available U. S.
census'data.5 The population density in the area within 50 kilometers
of a sQurce was estimated by summing the populations of all census
, . .
tracts:within a 50~kilometer radius of the facility and dividing by
the ar~a (7,850 km2). Geographical and terrain descriptions were
prepared by studyingU. S. Geological Survey maps and an atlas of the
United ,States.
-6-
-------
Determinina the Habitability of the Area Within 0.5 Kilometer of a
Source
The HEM generates a single point estimate for the point of maximum
concentration. In order to assess the reasonableness of the maximum
individual risk estimate, the point of predicted maximum concentration
has been examined to determine if that point was likely to be habitable.
Although the HEM provides a single point estimate as the point of
maximum concentration, there are several reasons that the point of
maximum concentration should be examined as an area of maximum
concentration when interpreting HEM results. First, there is
uncertainty associated with input parameters used in the HEM (e.g.,
emission rates, stack gas velocity). Second, even when a particular
model input may be well defined, such as in cases where years of
meteorological data are available, the input parameters may be better
characterized statistically (e.g., a mean with some variance) than by
a single point estimate. Third, the information on population
distributions near facilities and the assumptions employed in the HEM
are only intended to provide reasonable estimates of the re)ationship
between population distribution and modeled concentrations.
The HEM models emissions as though they originate with a single
point when actually individual emission points can be widely
separated. Because of the uncertainty in dispersion parameters, as
well as the uncertainty in dispersion modeling techniques, the maximum
concentration can reasonably be characterized as an area that reflects
the distribution of the probable points of maximum concentration.
Therefore, the area that surrounds the point of maximum concentrations
I
has also been examined. Following discussions with individuals
familiar with the HEM, meteorology, and dispersion modeling in
general, it has been decided, with EPA agreement, to examine the area
within a 0.5 kilometer radius of the point of maximum impact.
There is one additional reason for providing descriptive
information about the area surrounding the point of maximum modeled
concentration. If better or different information characterizing the
source to be modeled becomes available, the area predicted to experience
the maximum concentration may shift to a nearby point. In this case, it
-7-
-------
would be useful to know whether the new predicted point of concentration
was habitable.
U~ S. Geological Survey maps were examined to identify any
nonhabitable areas within a 0.5-kilometer radius of a source. The
distance and bearing of nonhabitable areas in relation to the source
and to the point of predicted maximum concentration were described.
Photocopies of the sections of the topographic maps containing the
source locations were made and the area within 0.5 kilometers of the
, . ,
source 'were delineated on them. The point of predicted maximum
concen~ration was .marked on the map with a small "x". The location of
the point of predicted maximum concentration relative to the location
of the 'source is described in the source summary sheet. When more
than one compound is emitted from a source and the points of predicted
maximum concentration of these compounds occur in different locations,
then the location of each point of predicted maximum concentration is
described. The Technical Project Officer provided overlays of
concentration grids, for each scale of map, for use in locating the
area within 0.5 kilometers of a source and the points of predicted
maximum concentrations. The photocopied maps and overlays are
included in Appendices A through F.
Verifvina Latitude and Lonaitude of Colocated Sources
Some emission sources, such as chemical plants, contain more than
one process unit that emit pollutants of concern. Often, these plants
submit 'a separate Section 114 response for each chemical. In these
cases, ,it maybe difficult to determine whether the chemicals are emitted
from t~e same process unit or are emitted from different (colocated)
process units, having different latitudes and longitudes, within the
same plant. Such differences in location may cause significant
differences in modeling results, particularly in some of the v~ry
large chemical plants, where process units may be located at considerable
distances from each other~ When this situation occurred, the Section
114 responses, when available, were examined to determine whether a
unique latitude and longitude were submitted for each process unit. If
-8-
-------
it remained unclear as to the colocation of process emission points, .
then ESED or SASD personnel who were working on the chemical or source
category were consulted.
. If these two steps failed to identify a reasonable latitude and
longitude, then the latitude and longitude of the process units or
directions to the process units were obtained from plant personnel.
If directions to the process unit~ were obtained, the latitude and
longitude were estimated from the topographic map. This procedure was
used to make a best estimate regarding the colocation of process
units.

DISCUSSION OF VERIFICATION RESULTS
The current latitude and longitude are identical to the coordinates

The Philadelphia STAR site is not the most representative site for
Delaware City. Delaware City is in a relatively open area along the Bay.
The Dover STAR site will be more representative of wind channeling in the
Bay area than the Philadelphia site would. It is recommended that the STAR
site be updated to Dover.

The current latitude and longitude differ from the coordinates
provided by the Illinois Environmental Protection Agency. The coordinates
provided by Illinois identify a point much closer to a plant in Danvi11e.
The verified latitude is the latitude provided by Illinois while the
verified longitude is the same as the current longitude.
The Rantou1 STAR site is the most representative site for this source.
Rantou1 and Danvi11e have similar. topography and are not subject to
micrometeoro10gica1 effects.

DISCUSSION OF VERIFICATION RESULTS
" Neither the current latitude and longitude nor the coordinates
provided by the South Coast Air Quality Management District identify a
plant. They identify points in a residential area of El Segundo. The
latitude and longitude were verified on "the U.S.G.S. map using directions
provided by plant personnel. The verified coordinates are very close to
the current ones.
The Los Angeles STAR site is the most representative site for this
source. Los Angeles and El Segundo are both near the ~oast and are
approximately 5 km apart.

III. DESCRIPTION OF AREA WITHIN 50 KILOMETERS OF SOURCE
Topography: Flat lowland to hills in coastal plain region of
California. Source is about 0.8 km S of the San Joaquin River and
3.5 km E of the city of Antioch. Montezuma Hills are about 9 km N of

-------
Location of nonhabitable areas relative to source: Ponds are 0.4 km
NNE, 0.5 km NNE, and 0.4 km NE of source.
Location of nonhabitable areas relative to predicted"maximum
concentration: Ponds are 0.25 km NNW, 0.25 km N, and 0.15 km NE of
predicted maximum concentration.
VI. DISCUSSION OF VERIFICATION RESULTS
The current latitude and longitude were verified on the U.S.G.S. map
as being reasonable. The coordinates provided by the Bay Area Air Quality
Management District differ by more than three minutes from the current
coordinates and do not appear to be reasonable.
The Fairfield STAR site is the most representative site for this
source because Fairfield and Antioch are on the same side of the coastal
range. Antioch does experience some local land and sea-breeze effects that
an inland site such as Fairfield does not experience. However, Fairfield
is more representative than the coastal STAR sites, San Francisco and.
Oakland, because these coastal STAR sites are on the other side of the
coastal range.

VI. DISCUSSION OF VERIFICATION RESULTS
The current latitude and longitude are very close to the coordinates
provided by the New Jersey Bureau of Air Pollution Control. The.
coordinates provided by New Jersey were verified on the U.S.G.S. map as
. being more reasonable, even though they are only one minute different from
the current coordinates.
The Philadelphia STAR site is the most representative of conditions in
Deepwater because both sites are located on the Delaware River. Wind flow
in Deepwater is not significantly influenced by the Delaware Bay.

VI. DISCUSSION OF VERIFICATION RESULTS
The current latitude and longitude differ slig~tly from the
coordinates provided by the Louisiana Department of Environmental Quality.
The coordinates provided by Louisiana were verified on the U.S.G.S. map as
being more reasonable.
The New Orleans STAR site is more representative of conditions in
Gramercy than the Baton Rouge STAR site because Baton Rouge is further
inland than New Orleans. Gramercy is located midway between New Orleans
and Baton Rouge.

The current latitude and longitude are very close to the coordinates
provided by the Kentucky Department of Environmental Protection. The
current coordinates verified on the U.S.G.S.map as being more reasonable.
The Paducah STAR site is the most representative site for Calvert
City. Paducah is located along the Ohio River and Calvert City is near the
Tennessee River. Some channelling of wind flow is expected in both river
valleys, but no significant difference is expected between the two sites.

DISCUSSION OF VERIFICATION RESULTS
The coordinates currently used and those provided by the New Jersey
Bureau of Air Pollution Control agree closely (within 4 seconds longitude).
The latitude and longitude provided by New Jersey, however, agree more
closely with the location of the closest industrial plant on the U.S.G.S.
map, and were therefore chosen as the verified coordinates.
. The STAR site selected by the HEM is considered the most appropriate
STAR site for this source. The Teterboro site, which is located north of
Elizabeth, is more representative of conditions in Elizabeth than the next
closest STAR site, #94789, located at JFK Airport. Elizabeth is more exposed
to ocean breezes than JFK Airport is.

DISCUSSION OF VERIFICATION RESULTS
The latitude and longitude provided in the Section 114 response from
this plant differed significantly from the current information. The current
modeling information located the plant near Akron rather than Cleveland. The
coordinates provided in the Section 114 response w~re verified on the
U.S.G.S. map as being more reasonable.
The verified coordinates locate the source near Cleveland, but within
the corporate boundary of Avon Lake, Ohio. The STAR site corresponding to
the verified source location is #14820 in Cleveland, Ohio. It is recommended
that the HEM be re-run with .the verified city, latitude and longitude, and
STAR site information.

DISCUSSION OF VERIFICATION RESULTS
The latitude and longitude currently being used to model carbon
tetrachloride emissions from this facility differs significantly from the
current information. The carbon tetrachloride modeling information was
verified on the U.S.G.S. map as being more reasonable. The current
information did not locate the source near Beaumont. It is recommended that
the HEM inputs be checked and updated to reflect the verified latitude and
longitude, if necessary.

DISCUSSION OF VERIFICATION RESULTS
The latitude and longitude provided by the Kentucky Department of
Environmental Protection agree closely with the current information. However,
the coordinates provided by Kentucky agree more closely with the location of
the nearest industrial plant on the U.S.G.S. map, and therefore they were
selected as the verified coordinates. The STAR site shown by the HEM is
located in Louisville and is considered the most representative site for this
source.

DISCUSSION OF VERIFICATION RESULTS
VI.
The current longitude is incorrect. It does not identify a plant
near Belle, West Virginia. The longitude submitted on the Section 114
questionnaire for carbon tetrachloride was incorrect. The longitude
currently used to model methylene chloride emissions from this source
was verified on the U.S.G.S. map as being the correct longitude for
this source.
The STAR site chosen by the HEM corresponds to the incorrect
latitude and longitude. The verified latitude and longitude will make
the Charleston STAR site the closest and most representative site.
The location of the predicted maximum concentration is expected
to change when the HEM is re-run with the verified longitude to 0.2 km
SW of source. This new location is in a nonhabitable area -- the
Kanawha River.

coordinates of this source verified for carbon tetrachloride and
methylene chloride emissions. The verified latitude is only 9 seconds
different and therefore it is not recommended that the HEM be re-run.
The current STAR site is the appropriate site for this location.
The predicted maximum concentration is currently located in a
nonhabitable area -- the Kanawha River, 0.2 km SW of the source.

VI. DISCUSSION OF VERIFICATION RESULTS
The current latitude and longitude identify a building in a large
industrial complex as the location of this plant. These coordinates
are reasonable~ They also agree with the coordinates provided by the
Texas Air Control Board.
The current STAR site is more representative of regional
meteorology than the Galveston or Houston sites, the two next closest
STAR sites. . However, Ingleside is located on the coast near Corpus
Christi and would be better represented by a Corpus Christi STAR site,
if it was included in the STAR data set. Corpus Christi should be
added to the HEM STAR data set. -

VI. DISCUSSION OF VERIFICATION RESULTS
The current latitude and longitude identified an area very close
to a chemical plant on the U.S.G.S. map. The latitude differed by 20
seconds from the latitude of the chemical plant. This difference is
so small that it is not recommended that the HEM inputs be changed.
The current STAR site is the most representative station for this
source. Although the hills surrounding this source may cause slight
variations in wind movement, the Morgantown STAR site is still more
representative than the next closest STAR site in Pittsburgh.

Location of nonhabitable areas relative to predicted maximum

predicted maximum concentration; 1 pond located 0.5 km NNE of
predicted maximum concentration. The predicted maximum
concentration is very near or in a nonhabitable area (pond 0.5 km
NNE).
VI. DISCUSSION OF VERIFICATION RESULTS
The current latitude and longitude identifies a small complex of
buildings 4-5 km north of Axis as the location of this plant. These
coordinates appear reasonable on the U~S.G.S map.
The STAR site chosen by the HEM, however, is not considered the
most appropriate site for Axis. Axis is located approximately 25 km
inland from Mobile Bay, while the current STAR site, at Pensacola, is
located on the coast. Although wind flow in Axis is influenced by the
Bay, Axis is not a true coastal site. The Milton/Whiting STAR site is
located about 50 km NE of the Pensacola STAR site, at the northern end
of East Pensacola Bay. The Milton STAR site is considered more
representative of wind flow patterns in Axis. Therefore, it is
recommended that the HEM be re-run with the Milton STAR site.
The predicted maximum concentration is currently very near or in
a nonhabitable area (pond). When the STAR site is changed, the
predicted maximum concentration may be .located in a nonhabitable area.

VI. DISCUSSION OF VERIFICATION RESULTS
The current latitude and longitude differ significantly from the
coordinates verified for carbon tetrachloride, perchloroethylene,
trichloroethylene, and methylene chloride emissions from this source.
It is recommended that the HEM be re-run with the verified latitude
and longitude. The current STAR site is the most appropriate site for
this location.

-------
Location of nonhabitable areas relative to predicted maximum
concentration: Large settling pond is <0.1 km N and small
settling pond is 0.1 km SW of predicted maximum concentration.
The predicted maximum concentration, therefore, is very near or
in a nonhabitable area (large settling pond).
VI. DISCUSSION OF VERIFICATION RESULTS
The current latitude and longitude identify a small complex of
buildings north of the Greens Bayou as the location of this plant.
These coordinates appear reasonable. Greens Bayou is not a
census-designated town. The closest census-designated town is
Cloverleaf, which is located 1-2 km north of the plant. The Houston
STAR site is the closest and most representative meteorological
station for Cloverleaf.
The predicted maximum concentration is very near or in a
nonhabitable area.

DESCRIPTION OF THE AREA OF PREDICTED MAXIMUM CONCENTRATION
Predicted maximum individual lifetime risk: 2.3 X 10-3 for EDC,
5.9 X 10-5 for carbon tetrachloride, 4.1 X 10-6 for chloroform, and
2.8 X 10-8 for trichloroethylene.
Predicted ~aximum concentration of compound: 86.607 ug/m3 of EDC,
3.9448 ug/m3 of carbon tetrachloride, 0.17749 ug/m3 of chloroform,
and 0.021524 ug/m3 of trichloroethylene.
Location of predicted maximum concentration: 0.2 km NNE of source for
EDC and carbon tetrachloride; 0.5 km NNE for chloroform and
trichloroethylene.

HABITABILITY OF AREA WITHIN 0.5 KILOMETERS OF SOURCE
Percent nonhabit~ble area: 5%
Description of nonhabitable areas: River
Location of nonhabitable areas relative to source: River is 0.4 km NNE
of source.
Location of nonhabitable areas relative to predicted maximum
concentration: The predicted maximum concentrations of EDC and carbon
tetrachloride are 0.2 km S of river. The predicted maximum
concentrations of chloroform and trichloroethylene are located in the
river.
VI. DISCUSSION OF VERIFICATION RESULTS
The current latitude and longitude differ slightly from the
coordinates provided by the Kentucky Department of Environmental
Protection. The coordinates provided by Kentucky were verified on the
U.S.G.S. map as being more reasonable. The predicted maximum
concentrations of chloroform and trichloroethylene (0.5 km NNE of source)
will be located in the river when the verified source location is modeled.
Because the verified latitude and longitude will affect habitability of the
area within 0.5 km of the source, it is recommended that the latitude and
longitude should be updated to reflect the verified coordinates.
The STAR site chosen by the HEM is the most appropriate site for this
source location. The STAR site will not change when the verified latitude
and longitude are used.

Location of nonhabitable areas relative to predicted maximum
concentration: Small pond is 0.3 km SSE of predicted maximum
concentrations of EDC and carbon tetrachloride and 0.6 km SSE of
predicted maximum concentrations of chloroform and trichloroethylene.
VI. DISCUSSION OF VERIFICATION RESULTS
The current latitude and longitude are unreasonable because they do
not identify a plant in La Porte. The coordinates provided by the Texas
Air Control Board are similar to the coordinates of the nearest chemical
plant. The verified latitude and longitude were estimated from the
U.S.G.S. map using the coordinates provided by Texas. It is recommended
that the latitude and longitude by updated to the verified coordinates;
The STAR site selected by the model is the most appropriate STAR site
for La Porte. The STAR site will not change when the latitude and
longitude are updated.

DISCUSSION OF VERIFICATION RESULTS
The current latitude and longitude are within severat seconds of the
coordinates provided by plant personnel. Latitude and longitude were not
available from the Louisiana Department of Environmental Quality or the
National Emissions Data System. No structures are apparent on the U.S.G.S.
map at the location identified by the current coordinates,because,
according to plant personnel, the plant was built in 1981, after this map
was last published. The current coordinates were therefore verified by
consulting plant personnel. The STAR site selected by the model is the
most representative site for Convent.

VI. DISCUSSION OF VERIFICATION RESULTS
The current latitude and longitude identify structures in a plant near
Freeport, Texas. This location is approximately 0.5 km north of the large
chemical plant containing other chlorinated organics production units.
Dow's Freeport plant is extremely large and spread out and therefore the
current coordinates appear reasonable.
The STAR site selected by the HEM is the most representative site for
Freeport. This STAR site has been verified in previous validation tasks.

DISCUSSION OF VERIFICATION RESULTS
The current latitude and longitude do not identify a plant in Oyster
Creek. The coordinates provided by the Texas Air Control Board identify a
plant in Oyster Creek and they were verified on the U.S.G.S. map as being
more reasonable. Although the verified coordinates differ from the current
coordinates by less than one minute thirty seconds, habitability of the
area within 0.5 km of the source will change significantly if the verified
coord i nates are used. Therefore it is recommended that the 1 at i tude 'and
longitude be updated to the verified coordinates.
The STAR site selected by the model is the most representative site
for this source. The STAR site will not change when the latitude and
longitude are updated.

DISCUSSION OF VERIFICATION RESULTS
The current latitude and longitude are not reasonable because they do
not identify a plant in or near Point Comfort. The coordinates provided bY
the Texas Air Control Board are near a large plant in Point Comfort. The
verified coordinates were estimated from the U.S.G.S. map by using the
coordinates provided by Texas. These coordinates differ by more than. one
minute thirty seconds from the current latitude and longitude. Therefore,
it is recommended that the latitude and longitude be updated and the model
re-run for this source.
The STAR site selected by the model is the most appropriate site for
this source. The next nearest STAR site is Galveston, which is
approximately 190 km northeast of Point Comfort. The Beeville site is more
representative than Galveston because Beeville is nearer to the source.
The STAR site will not change when the latitude and longitude are updated.

VI. DISCUSSION OF VERIFICATION RESULTS
The current latitude and longitude differed slightly from the
coordinates provided by the Louisiana Department of Environmental Quality.
The latitude and longitude provided by Louisiana were verified on the
U.S.G.S. map as being reasonable. Since these coordinates differ by,less
than one minute thirty seconds from the current coordinates and
habitability is not affected by the difference in coordinates, no change in'
the model inputs is recommended. .
The STAR site selected by the model is the most representative s'ite
for this source. This STAR site has been verified in a previous validation
task.
