Repeat notification owed when work outruns the ticket, scope expands, or a temporary excavator is added

The excavator must repeat the § 12-124 notification if they have not completed or will not complete the work within the time period authorized by the ticket, expand beyond the location in the original notice, or add a temporary excavator to the ticket. Repeat notice is required regardless of owner-member marking delays or any private agreement on marking time.

Re-marking request when marks are obliterated or a facility shows unmarked

If a mark is obliterated, destroyed, or removed, or a visible indication shows an underground facility is not marked as required, the excavator must notify the one-call system to request that all or part of the current scope of work of a valid ticket be re-marked. Re-marking is a defined statutory step, distinct from filing a new ticket.

No digging until all notified owner-members have given a positive response

Digging may not begin until all notified utility owner-members have provided a positive response through the Ticket Check system. Every company on a Maryland job must have a separate one-call ticket number or be listed and acknowledged as a valid temporary excavator before excavating; contractors working for a homeowner may not dig on the homeowner's ticket.
