MNG Excess Flow Valves (EFV)
In rare cases, careless excavation work can damage the gas lines that serve you. For added protection, installing an Excess Flow Valve (EFV) can shut off the flow of natural gas automatically if the line is damaged or broken. EFVs are not designed to shut off the flow of natural gas for low volume leaks or a faulty appliance. Click Here for more information.
Dig Safe is a not-for-profit clearinghouse that notifies participating utility companies of your plans to dig. In turn, these utilities (or their contract locating companies) respond to mark out the location of their underground facilities. Dig Safe is a free service, funded entirely by its member utility companies. (Note: Dig Safe does not mark utility lines.)
Many of the pipeline leaks and emergencies we respond to each year happen when homeowners and businesses dig on their property without knowing the location of underground utility lines. These types of accidents are called third-party damages, and they are easily avoided by calling 811 before you dig – anywhere on your property.
Maine Natural Gas is a sponsor of M.U.S.T. which is an organization that promotes underground facility safety through training efforts in cooperation with Dig Safe, underground facility owners, private locating companies, municipalities, excavators and regulatory agencies, and to continually evaluate the New England one-call laws and underground safety best practices.

Calling 811 is FREE.
When you call 811, the utility lines on your property will be marked, preventing you from damaging them when you dig. Project examples that warrant a call to 811 include the installation of:
- Septic tanks and sewer lines
- Swimming pools
- Sprinkler systems and water lines
- Basketball goal posts or mailbox posts
- Fence and deck posts
- Trees and shrubs
It’s a risk to make faulty assumptions about when to notify Dig Safe. That’s why state law requires you to notify Dig Safe for even small projects, like installing a mailbox or planting shrubs. The depth of utility lines vary, and there may be multiple utility lines in a common area.
It’s important to know what’s below. Call 811 to avoid utility service disruption to an entire neighborhood, harm to you and those around you, as well as fines and repair costs.
Not all owners of underground facilities are required to be members of the Dig Safe system. Please refer to the Maine Public Utilities Commission’s “OK-TO-DIG” directory, provides contact information for the non-member, underground facility operators.
