b Interpolation of the data in this table for process weight rates up to 60,000 lb/hr shall be accomplished by use of the equation:
E = 4.10P0.67
 and interpolation and extrapolation of the data for process weight rates in excess of 60,000 lb/hr shall be accomplished by the use of the equation:
E = 55.op0.11 - 40
Where:
   E = rate of emission in lb/hr and
   P = process weight rate in tons/hr
