If excavation does not start within sixteen calendar days from the time of the OHIO811 excavation notification being submitted (811 ticket), or if a utility marking is destroyed or removed at any time, the excavator must stop working and notify OHIO811 again.

To be clear, Ohio law states the following:

“(A) Except as otherwise provided in divisions (C), (D), (E), and (F) of this section, at least two working days, not including the day of the notification, but not more than sixteen calendar days before commencing excavation, the excavator shall notify the protection service of the location of the excavation site and the date on which excavation is planned to commence.” — ORC 3781.28(A)

“(B) If the markings of underground utility facilities made under section 3781.29 of the Revised Code are destroyed or removed before excavation is completed, the excavator shall notify the utility through the protection service that the markings have been destroyed or removed, and the utility shall remark the facilities in accordance with section 3781.29 of the Revised Code.” — ORC 3781.31(B)
