Underground Asset Protection/Damage Prevention
ComEd is committed to preventing serious accidents and fatalities that can result when excavators, contractors and others do not use proper care to avoid contact with underground and above ground electrical facilities. Our primary concern is safety.
Call Before You Dig
Before you dig or drive equipment into the ground, by Illinois law you must call the appropriate one-call system (numbers listed below) at least 48 hours before working. The one-call center will then notify ComEd and other utilities of the project. The utilities will mark their facilities.

- Outside the Chicago city limits call: "J.U.L.I.E." (Joint Utility Locating for Excavators) 1-800-892-0123 or visit their website
