No owner or other person shall cause or permit to be discharged into the atmosphere from any primary metal operation any sulfur oxide emissions in excess of the following limits:
Copper Smelters: Y = 0.2X
Zinc Smelters: Y = 0.564X0.85
Lead Smelters: Y = 0.98X0.77
where:
X = total sulfur fed to the smelter in lb/hr.
Y = allowable sulfur oxide emissions in lb/hr.
Note: This provision in effect requires removal of about 90% of the input-sulfur to the smelter.
