About the Illinois State Plan [Illinois State Plan Website]

On September 1, 2009, the Illinois Public Employee Only (PEO) State Plan was approved as a developmental plan under Section 18 of the Occupational Safety and Health Act of 1970 and 29 CFR 1956.

The Illinois PEO State Plan is administered by the Illinois Department of Labor (IDOL). The department's Public Employee Safety and Education Division is responsible for compliance program administration, conducting enforcement inspections, adoption of standards, and operation of other OSHA related activities in the public sector. Federal OSHA retains full authority for coverage of private sector employees in the State of Illinois as well as for coverage of Federal government employees.
