The Board may consolidate into a single rulemaking under this Section all such federal regulations adopted within a period of time not to exceed 6 months.
     The provisions and requirements of Title VII of this Act shall not apply to rules adopted under this subsection (a). Section 5-35 of the Illinois Administrative Procedure Act relating to the procedures for rulemaking shall not apply to regulations adopted under this subsection (a).
     (b) The Board may adopt regulations relating to a State municipal solid waste landfill program that are not inconsistent with the Resource Conservation and Recovery Act of 1976 (P.L. 94-580), or regulations adopted thereunder.
