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.
