(b) In determining an alternative allowable emission rate for sulfur dioxide, the formula established in paragraph (a) of this subsection shall utilize values for allowable emissions rates for an affected facility stated in terms of total rated heat input capacity based on the use of the same fuel category (solid, liquid, or gaseous fuel), which shall be determined by utilizing the formulas established in Section 5 of this administrative regulation.
