1. (a) Where the process weight rate is not explicitly listed in Table 2102-1, the maximum allowable particulate matter emission rate shall be calculated using the applicable equation in (b) or (c), below, where:

   1. (1) “E” means the maximum allowable particulate matter emission rate in pounds per hour (lb/hr); and
   2. (2) “P” means the process weight rate in tons per hour (tons/hr).

2. (b) For a stationary source or device installed prior to or on February 18, 1972, if the process weight rate is:

   1. (1) Up to 30 tons/hr, P shall be raised to the 0.67 power and multiplied by 5.05, as shown in the formula below:

      E = 5.05 P^0.67

   2. (2) In excess of 30 tons/hr, P shall be raised to the 0.11 power and multiplied by 66.0, and then 48 shall be subtracted from that result, as shown in the formula below:

      E = 66.0 P^0.11 - 48

3. (c) For a stationary source or device installed after February 18, 1972, if the process weight rate is:

   1. (1) Up to 30 tons/hr, P shall be raised to the 0.67 power and multiplied by 4.10, as in the formula below:

      E = 4.10 P^0.67

   2. (2) In excess of 30 tons/hr, P shall be raised to the 0.11 power and multiplied by 55.0, and then 40 shall be subtracted from that result, as in the formula below:

      E = 55.0 P^0.11 - 40
