where:
n = number of carcinogenic metals
AFR = actual feed rate to the device for metal "i"
FRSL = feed rate screening limit provided by appendix XVI of 33-24-05 for metal "i".
TESH = Ha+H1-Tr
where:
Ha = Actual physical stack height
H1 = Plume rise as determined from appendix XXI of 33-24-05 as a function of stack flow rate and stack gas exhaust temperature.
Tr = Terrain rise within five kilometers of the stack.
K = HVT
where:
K = a parameter accounting for relative influence of stack height and plume rise;
H = physical stack height (meters);
V = stack gas flow rate (m3/second); and
T = exhaust temperature (°Kelvin).
The stack with the lowest value of K is the worst-case stack.
where:
n = number of carcinogenic metals
AER = actual emission rate for metal "i"
ERSL = emission rate screening limit provided by appendix XVI for metal "i".
Where:
(n = number of carcinogenic metals)
