  5. Q: I'm only digging a couple of inches; do I still need to call Miss Utility?
    A: YES, you do! Anytime you alter the surface of the ground, it is considered excavation; this includes but is not limited to: driving pins, rods, and fence posts in the ground.
  6. Q: When can I dig?
    A: Each state has its own set of laws that identify the time by which the underground facilities should be marked. You should never dig unless you see evidence that the owner-members have marked or cleared your ticket.

    DELAWARE: Everyone in Delaware must give notice two (2) full working days prior to the day they plan to start work and have contacted the Delaware Ticket Check System.  The day of the call is not counted as one of these days.

    MARYLAND: Everyone in Maryland must give two (2) full business days prior to the day they plan to work and have contacted the Maryland Ticket Check System.

    WASHINGTON D.C.: 2 Business Days from the time the locate markings are requested.
  7. Q: How will I know where the underground facilities are located at my excavation site?
    A: If there are underground utilities near your excavation site, they will be marked on the ground with paint and/or flags. In the states of Delaware or Maryland, call the Ticket Check System to retrieve the status of your locate request at (866) 821.4226 or click here to search your locate request.
    • In Washington D.C., some owner-members use the Ticket Check System and others provide their own positive response. Owner-members not using Ticket Check will notify you if the area is clear/no conflict or the marked utility lines will serve as the owner-member’s response.

These maps are available at your local convenience store or by contacting ADC directly at www.adcmaps.com . For Somerset County , the center uses the Somerset County Roads Map (produced by ADC). This map is available by visiting the Somerset County Visitors Center or calling Somerset County at (410) 651-0320.

    A: Depending on the state where you operate, you could receive any one of the following tickets unless it is noted as state specific.
    STANDARD (does not appear on the ticket as a header)
    UPDATE (does not appear on the ticket as a header)
    MEETING (DE only)
    DESIGNER (DE & MD only)
  15. Q: Why don’t owner-members and locators provide the depth of the underground facilities?
    A: Owner-members have no control over depth variations caused by human interference, weather, or other circumstances after the original installation. As a result, locators will only mark the path of the underground utility lines, not the depth of them.
  16. Q: What will be different about the Delmarva calls now that mapping is in place?
    A: In order for us to digitally map an excavation site, the Call Center CSR's may be asking the excavator a few additional questions. For instance, how far from the intersection and in what direction is your excavation site? Or, are you digging on the north, south, east or west side of the road? Or, how far off the street is your excavation? These types of questions will enable our CSR's to better identify your dig site, so we can notify the utility members of your excavation. We appreciate your time and effort in providing the best possible information to our CSR's in order to minimize your time on the telephone, while improving efficiency in the call taking process.
