Interpolation of the data for the process weight rates up to 60,000 lbs/hr. shall be accomplished by the use of equation:
E=3.59 P0.62 P is less than or equal to 30 tons/hr.
and interpolation or extrapolation of the data for process weight rates in excess of 60,000 lbs/hr. shall be accomplished by use of the equation:
E=17.31 P0.16 P is greater than 30 tons/hr.
Where: E=Emission in pounds per hour.
P=Process weight rate in tons per hour.
