B. Except as provided in subsections C and D of this section, interpretation of the emission standard in subsection A of this section shall be in accordance with 9VAC5-40-22.
C. Interpolation of the data in Table 4-4A for process weight rates up to 60,000 lb/hr shall be accomplished by use of the following equation:
E = 4.10 P0.67
where:
E = emission rate in lb/hr.
P = process weight rate in tons/hr.
D. Interpolation and extrapolation of the data for process weight rates in excess of 60,000 lb/hr shall be accomplished by use of the following equation:
E = 55.0 P0.11 - 40
where:
E = emission rate in lb/hr.
P = process weight rate in tons/hr.
