Additionally, if the Board, after adopting an "identical in substance" rule, determines that a technical correction to that rule is needed, the Board may initiate an application for certification of correction under Section 5-85 of the Illinois Administrative Procedure Act.
The one-year period may be extended by the Board for an additional period of time if necessary to complete the rulemaking proceeding. In order to extend the one-year period, the Board must make a finding, based upon the record in the rulemaking proceeding, that the one-year period is insufficient for completion of the rulemaking, and such finding shall specifically state the reasons for the extension. Except as otherwise provided above, the Board must make the finding that an extension of time is necessary prior to the expiration of the initial one-year period, and must also publish a notice of extension in the Illinois Register as expeditiously as practicable following its decision, stating the specific reasons for the Board's decision to extend. The notice of extension need not appear in the Illinois Register prior to the expiration of the initial one year period and shall specify a date certain by which the Board anticipates completion of the rulemaking, except that if a date certain cannot be specified because of a need to delay adoption pending occurrence of an event beyond the Board's control, the notice shall specify the event, explain its circumstances, and contain an estimate of the amount of time needed to complete the rulemaking after the occurrence of the specified event.
