Special Formula
Section 214
Section 214.184 Special
Formula
a) If the maximum total emissions of sulfur dioxide into the
atmosphere in any one hour period from all fuel combustion emission sources
owned or operated by any person and located within a 1 mile (1.6 km) radius
from the center point of any such fuel combustion emission sources exceed,
during normal cyclical variations in firing rate and fuel, the emissions
allowed under Section 214.183 but, as of April 1, 1978, were in compliance with
either the formula detailed below or a Pollution Control Board (Board) order,
then the owner or operator of the emission sources shall not cause or allow
such emissions to exceed the emissions allowed under Section 214.183 or the
formula detailed below, whichever the owner or operator of the emission sources
determines shall apply.

=
total
emission of sulfur dioxide in lbs/hr or kg/hr into the atmosphere in any one
hour period from all fuel combustion emission sources owned or operated by
such person and located within a 1 mile (1.6 km) radius from the center point
of any such emission source;
P

=
(for i = 1,

as decimal equivalents (e.g., 21% = 0.21); and
H
i
=
(for i = 1,
