What are gas line maintenance requirements?
Minnesota Energy Resources complies with the United States Department of Transportation (DOT) order that requires us to notify customers who may own buried natural gas piping not maintained by Minnesota Energy Resources that the customers is responsible for maintaining the buried piping (an example would be the piping that connects the gas meter to a customer's natural gas line).

"Maintain" means to monitor buried piping for corrosion and survey for leaks, and if an unsafe condition is found, shut off the flow of gas. If Minnesota Energy Resources becomes aware of an unsafe condition we will advise the customer of the need to repair the unsafe condition, or assist in repairing the unsafe condition.

What are customers' responsibilities regarding buried piping?
Minnesota Energy Resources does not maintain customer-owned buried piping. All customers should have a qualified professional periodically inspect the buried piping for leaks and/or corrosion. If the buried piping is not maintained, it may be subject to potential hazards of corrosion and leakage.

Customers' buried gas piping (not owned by Minnesota Energy Resources) should be repaired or replaced if any leaks or unsafe conditions are discovered.
