25 Pa. Code § 123.24 - Primary zinc smelters
(a) No
person may permit the emission into the outdoor atmosphere of sulfur oxides
from any zinc roasting operation in such a manner that the concentration of
sulfur oxides, expressed as SO2, in the effluent gas
exceeds 500 parts per million by volume, dry basis, calculated as a 2-hour
moving average.
(b) No person may
permit the emission into the outdoor atmosphere of sulfur oxides from any zinc
sintering operation in excess of the rate calculated by the following formula:
Y = 0.054X,
Where:
X = Calcine feed rate to the sinter plant (lbs/hr); and
Y = Allowable sulfur oxide emissions (lbs/hr).
