When you notify OHIO811 before you begin your project, utilities registered with OHIO 811 will mark the approximate location of their underground lines in the digging area. It is important to dig with care when excavating near the markings and to respect the “tolerance zone,” which spans the width of the utility line, plus 18 inches on both sides of the line width. Learn more about the “Tolerance Zone” by carefully reviewing the “Duties of an Excavator” in ORC 3781.30 and the definition of Tolerance Zone in ORC 3781.25(E) at www.OHIO811.org/law

Please note that unregistered lines, including some service lines and privately-owned lines, may not be marked. You should contact a private locating company if you believe you have additional lines in your excavation area.
