§ 90.025  INDUSTRIAL PROCESS EQUIPMENT.
   (A)   (1)   The maximum allowable emission of particulate matter from any source whatever, except fuel burning and refuse burning equipment, shall be determined from the table as set forth below.
      (2)   When using the table, the process weight per hour shall be found in the table and the allowable rate of emissions in pounds per hour next to the process weight per hour shall be found.
   (B)   For those processes whose process weight exceeds 200 tons per hour, the maximum allowable emission may exceed that shown in the table; provided that, the concentration of particulate matter in the discharge gases is less than 0.05 grains per standard cubic foot of gas.

   (C)   Interpolation of the data in the table above for process weight rates up to 60,000 pounds per hour shall be accomplished by use of the equation E equals 4.10 P 0.67, and interpolation and extrapolation of the data for process weight rates in excess of 60,000 pounds per hour shall be accomplished by use of the equation E equals 55.0 P 0.11-40, where E equals rate of emission in pounds per hour and P equals process weight in tons per hour.
