625 ILCS 5/18a-407
All dispatcher's employment permits shall expire 2 years from the date of issuance by the Commission. The Commission may temporarily extend the duration of an employment permit for the pendency of a renewal application until formally approved or denied. Upon filing, no earlier than 90 nor later than 45 days prior to such expiration, of written application for renewal, acknowledged before a notary public, in such form and containing such information as the Commission shall by regulation require, and accompanied by the required fee, the Commission shall, unless it has received information of cause not to do so, renew the applicant's dispatcher's employment permit. If the Commission does not renew such employment permit, it shall issue an order setting forth the grounds for denial. The Commission may at any time during the term of the employment permit make inquiry into the conduct of the permittee to determine that the provisions of this Chapter 18A and the regulations of the Commission promulgated thereunder are being observed.
