SUBPART A: GENERAL PROVISIONS
Section 101.100 Applicability
a) This Part sets forth the rules generally applicable to proceedings before the Illinois Pollution Control Board (Board), and should be read in conjunction with procedural rules for the Board's specific proceedings, found at 35 Ill. Adm. Code 102 through 130, and the Board's Administrative Rules, found at 2 Ill. Adm. Code 2175. If the rules of this Part and those found in subsequent Parts conflict, the more specific requirement applies.
b) Except when the Board's procedural rules provide otherwise, the Code of Civil Procedure [735 ILCS 5] and the Supreme Court Rules [Ill. S. Ct. Rules] do not apply to proceedings before the Board. However, the Board may look to the Code of Civil Procedure and the Supreme Court Rules for guidance when the Board's procedural rules are silent.
