What are gas line maintenance requirements?

MGU 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 MGU 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 MGU 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?

MGU 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 MGU) should be repaired or replaced if any leaks or unsafe conditions are discovered.

The portion of buried piping that you own is generally the portion of gas line on your side of the meter. Many customers do not own any buried gas piping.

Signs of a natural gas leak include:

• Areas of dead vegetation directly above the buried piping

• Distinct natural gas odor

If you think you may have a gas leak, leave the house immediately and call MGU at 800-401-6451.

How do I locate buried piping?

When excavating near buried gas piping, the piping must be located in advance, and the excavation done by hand. Call MISS DIG at least three working days prior to digging for assistance in locating underground utilities in the area.
