Summary
This rulemaking is filed pursuant to Section 5-15 of the Illinois Administrative Procedure Act and is only changing the address of the Department's Springfield Office to reflect the fact that the office is moving on September 23, 2026. Section 5-15 of the Illinois Administrative Procedure Act requires agencies to include a statement of how the proposed rule made under this Section satisfies the criteria established by subsections (a) and (b). The Department's address is used by the public to obtain information from the Department and/or make submissions or requests of the Department. These members of the public may include insurance companies, persons licensed by the Department, and Illinois insurance consumers. The address provided in the rules should be accurate, otherwise such persons may go to or send correspondence to the wrong address. The decision to relocate the Springfield office was an internal management decision. The private rights of individuals are not affected by Department rules containing the accurate address, although having the incorrect address in rule will cause unnecessary confusion and delay for people seeking information from and/or making submissions to the Department in person or via mail. It is in the public interest to have the Department's office address published in the Illinois Administrative Code be correct.
