Federal Guidelines

State Utility Regulation

  • JULIE: Illinois law requires all persons digging, regardless of the depth of the project, to call JULIE at 1-800-892-0123 at least 48 hours (two working days) prior to the start of excavation and to begin that excavation project within 14 calendar days from calling JULIE. (The 48 hour notice does not include Saturdays, Sundays, or holidays.) Failure to contact JULIE prior to excavation in accordance with the law can carry penalties from $200 up to $5,000 for each separate offense. The Illinois Commerce Commission is the enforcement body for the law, not JULIE.
  • JULIE Enforcement: On July 27, 2001 , Governor Ryan signed House Bill 2138 (Public Act 92-0179) revising the Illinois Underground Utility Facilities Damage Prevention Act. The Act outlines the responsibilities of underground of utility facility operators and excavators with regard to notifying the State-Wide One-Call Notice System (otherwise known as "JULIE"), marking the underground utility facilities, and excavating near utility facilities. One of the revisions to the Act was to make the ICC responsible for enforcement of violations of the Act.

These statewide map show those state routes where a lane closure on the roadway is expected to cause sustained work zone impacts that are not considered tolerable based on the goals and objectives of this policy or public opinion and, thus, are considered Significant Routes. Roadways marked in red are considered as Significant Routes. Roadways marked in yellow are approaching Significant Route designation and should be evaluated for potential impacts.
