Notify 811 before you dig or move earth in any way. It’s the law! This free service will arrange for Pepco and other 811 member utilities to locate and mark their underground lines so you can dig a safe distance away from them.
Dial 811 or place an online locate request at missutility.net, then wait your state’s required time for facility owners to mark their lines before you dig:
- Maryland and D.C.: Wait two full business days, excluding weekends and legal holidays.
Pre-mark your proposed excavation area with white paint, flags, and/or stakes before you contact 811.
Wait for utilities to be marked before digging. Once utilities are marked, respect the marks, hand expose to verify location, and dig with care.
Always contact your state 811 center before digging and for the most current requirements
Notify 811 well ahead of digging, so underground utilities can be marked and you can work safely.
