Always notify 811 well in advance of digging.
If you plan to dig, blast, bore, trench, drill, grade, excavate, or move earth in any way, state law requires you to notify 811 prior to the start of any digging. This service will arrange the marking of underground natural gas lines and other buried utilities in the area of your planned work so you can dig a safe distance away from them. Dial 811 or enter an online locate request, then wait the required time for lines to be marked: three business days in Pennsylvania and two business days in West Virginia. Before you call, pre-mark your excavation area with white paint, flags, and/or stakes so locators can easily identify and mark affected utilities.
Watch out for pipeline markers that indicate the need for extra care around a natural gas transmission line.
Keep in mind that, for security purposes, these markers do not indicate the depth of pipelines or their exact locations. In addition, not all pipelines follow a straight path between markers.
The markers provide a toll-free number for reporting problems 24 hours a day, 7 days a week.
Call this number if you notice any unusual or suspicious activities nearby, or if you see construction-related activity and no utility personnel are on-site.
Like pipeline markers, online maps indicate the approximate locations of major natural gas pipelines.
To view these maps, visit the National Pipeline Mapping System website.
Pipeline markers and maps indicate only a general location of pipelines.
They should never be used as a substitute for calling 811 well in advance of digging.
Always contact your state 811 center before digging and for the most current requirements.
Dial 811 or use the online ticket-entry system before you dig so underground utilities can be marked for your safety.
