For

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

 to downwind distance in feet, tm is equal to

m

stack height to the height of the plume rise.

 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).

must have been collected during a field study

having a minimum duration of

 3 years.

(h)

mine background sulfur dioxide concentrations

standard.
