How Long is a Ticket Valid?
The ticket life on a standard excavation ticket shall be 17 calendar days after the start date and time on the ticket. Refresh tickets should be requested anytime marks are destroyed or become unusable, but a refresh will be required if work will continue beyond the expiration date.
The proposed excavation area on a ticket should be limited to that which can reasonably be completed within the 17 days. If the excavation is not completed by day 14, a refresh ticket should be placed with the center.
The ticket life shall not supersede the requirement that markings shall be done in a manner that will last for a minimum of five business days on any nonpermanent surface and a minimum of ten business days on any permanent surface.
