If such requirements are less stringent than the requirements contained herein, the conditions of this certification which are referred to by reference to the Florida Administrative Code shall be automatically modified consistent with such rule. In the application of such later adopted rule, this paragraph shall not be construed to mean that the R.F. Ellis, Jr. plant is a new source if a distinction between new and existing sources is made within the later adopted rule.

      b.   On its own motion or on petition of the applicant and, after review of such information as the Department deems appropriate, the Department may, by order of the Secretary or his designee, modify the conditions of this certification as it deems necessary to attain the objectives of Chapter 403, Florida statutes. The Department shall provide notice and an opportunity for hearing in accordance with Chapter 403 and Chapter 120, Florida Statutes, and rules and regulations adopted thereto.
