digExcavation damage is the leading cause of serious natural gas pipeline incidents. Careless digging can damage underground utilities, causing disruption of vital services, property damage and even possible injury. Taking the proper steps to avoid damage can prevent expensive repairs, project delays and costly fines.

Join us at our 3rd Annual Dig Safely Fairs and learn how to safely dig around natural gas facilities, identify a natural gas leak and keep your property safe. Click here for locations and dates for our Dig Safe Fairs. And remember ...

At least three business days, prior to outdoor construction or digging, contractors and property owners – whoever is excavating – must call New Jersey One Call at 811 or 800-272-1000 and take the following steps:

  • Wait for the site to be marked with paint, flags or stakes. Yellow indicates the presence of underground natural gas lines.
  • Respect the marks and dig with care.
  • Hand dig within two feet of buried piping and facilities.
  • Be mindful inclement weather may wash away the painted markings.

Don’t make assumptions about whether or not you should have your utility lines marked. Every digging job requires a call to 811 – even small projects like planting trees and shrubs.
