For
(4)
above, calculate the concentration profile downwind
of the facility at 20 minute intervals, calculating the height
of the mixing layer at
20 minute intervals using the rate of
rise given in item

above.
Nine 20—minute average concentra-
tions will be calculated to yield the 3-hour maximum ground-
level concentration.
If the IEPA AQSTM is used to calculate the ground-level
concentration under the fumigation situation, the maximum con-
centration will be that concentration at a distance x
=
14.44
t
where x is equal
to downwind distance in feet, tm is equal to
m

stack height to the height of the plume rise.

centrations.

If appropriate meteorological information speci-
fic to the site of the subject facility is avail-
able,
then such information may be used in
place of the conditions described in paragraphs
(1)
through
(4).
Such meteorological information
must have been collected during a field study
having a minimum duration of
3 years.
(h)
estimates of the frequency, characteristics, probable
time of occurrence, and duration of meteorological

mine background sulfur dioxide concentrations
in the
vicinity of the subject facility for each of the
meteorological conditions required to be examined

conditions considered
in developing the alternative
standard.
