It's not safe to demolish a structure until the natural gas service line is disconnected from the mainline. The owner or contractor may be liable for damages if a structure is demolished before Columbia Gas of Ohio completes this work.
- Call us at least 30 days in advance to make an "abandonment" request (1-800-344-4077).
- Not sure whether the service line has been abandoned? Call us.
- Also, be sure to call 811 to have all underground utilities located before demolition or any excavation.
