Always Call Before You Dig
National One-Call Number is 811

Dig-in (excavation) damage is a leading cause of gas system damage.  To minimize this hazard, the most important thing you can do is Call Before You Dig.  Minnesota offers a free statewide service that allows utilities to locate any buried facilities they own before you start digging.  Just call 3 business days before digging and provide the requested information to the operator.
