1973.
The summary shall include
annual averages; maximum and second—highest one—
37—82
—3—

month.
(d)
A summary of any and all meteorological data col-

which were used to develop the site—specific
emission limitation including all model equations.
(f)
A description of and justification for the use of
all data which were inputs to the dispersion and

specific emission standard.
The description and
justification shall cover,
as a minimum,
the
following input data:
1.
Stack diameters,
stack heights, exit gas
temperatures, and exit gas velocities for all
stacks and vents emitting sulfur dioxide at
the subject facility as well as for any other
sources of sulfur dioxide which were modeled;
2.
All SO2 emission sources which were modeled;
3.
All meteorological data.
(g)
Calculated maximum ground—level concentrations
using the following method, or such other method
(or modification of the hereinafter stated method)
which the petitioner proves to the satisfaction of
the Pollution Control Board to be acceptable.
1.
Selection of simulation model:
(i)
Gaussian models which allow the input of
hourly meteorological data shall be used
which are appropriate
for the specific
location and type of source(s)
in ques-
tion.
(ii)
Dispersion models presented in “Guide-
lines on Air Quality Models”
(EPA—450/2—
78—027),
as amended from time to time,
or those deemed by the Board
to be
equivalent to these models shall be
used
for detailed air quality studies.
37.—~:3
—4—
2.
Selection of meteorological data and stack
parameters:
(i)
The most recent five years of hour-by—
hour meteorological data reasonably
available,
including wind speed, wind
direction,
atmospheric stability, mixing
height and surface temperature shall
he
used, unless the petitioner demonstrates
that one of the five years causes sub-
stantially higher concentrations than
the other
four, in which case detailed
analyses conducted for only that “worst
case” year would be acceptable.
Notwith-
standing the previous sentence, one year
of on-site data may be used in lieu of
the 5—year data requirement.
(ii)
Data shall be from the nearest, repres-
entative, quality controlled meteorologi-
cal collecting site.
(iii)
Stack parameters (including emission
rate,
stack height,
stack diameter, exit
velocity,
and exit temperature)
shall
reflect the maximum operating rate for
comparison with the 24-hour and 3-hour
SO2 standards.
3.
Receptors:
(i)
Receptors shall be located so as to en-
sure that the source’s maximum impact is
detected.
(ii)
The determination of
the
receptor grid
shall be
fully documented in the model-
ing study.
4.
Special conditions:
(i)
All special conditions which may affect
the dispersion of the effluent plume,
including local terrain effects and
aerodynamic downwash, shall
be consid-
ered in the modeling study.
(ii)
If terrain is
a factor
in the vicinity
of the source,
a model capable of hand-
ling variable—height receptors shall be
used.
37—84
—5—
(iii)
If the computed height of the effluent
plume is
less than 2.5 times the height
of nearby buildings or local obstruc-
tions, aerodynamic downwash shall
be
studied and considered as
a possible
factor in the dispersion of that
effluent.
5.
Determination of violation:
The determination of whether an applicable
air quality increment or standard is being
violated shall be based on the second highest
predicted concentration over the receptor
grid for short—term averaging times and on
the highest predicted concentration for
annual averaging times.
However,
if only one
year of meteorological data is used in the
short—term analysis, then the highest predic-
ted concentration may be compared to the
applicable standard to determine whether a
violation has occured.
6.
Other sources:
Effects of other sources of SO
shall
be
taken into account in the mode~ingstudy.
(i)
An acceptable method is to estimate the
“background” from monitoring data which
has been subjected to adequate quality
control where available.
When monitored
data is used, the background shall
he
estimated using monitoring days with
meteorological conditions similar to
those identified as
“worst case” for the
source in question.
(ii)
If monitoring data is not available,
then all sources of SO2 having
a signifi—
cant impact in the area of the source’s
impact area shall he used in the simula-
tion model.
These sources of SO2 shall
also he modeled at their maximum allow-
able emission rate for any studies
addressing 24—hour or 3—hour averaging
times.
(h)
Estimates of the
frequency, characteristics, prob-
able time of occurrence,
and duration of the
meteorological conditions associated with the
maximum ground—level concentration of sulfur diox—
ide to which the facility under study contributes.
37—85
—6—
A description of the techniques used in arriving
at the above estimates shall be included.
(i)
Background concentrations which were determined
for all meteorological conditions required to be
examined under Rule 622(g) and for any other
meteorological conditions considered in the devel-
opment of the alternative standard;
(j)
A description of the method that was used to deter-
mine background sulfur dioxide concentrations in
the vicinity of the subject facility for each of
the meteorological conditions required to be
examined under Rule 622(g)
and for any additional
meteorological conditions considered in developing
the alternative standard.
(k)
An evaluation and calibration of the dispersion
model
if air quality monitoring data were avail-
able to perform such evaluation and calibration.
623
Parties
The Agency shall he a party to any hearing held pur-
suant to this Part.
624
