Pipeline Integrity and Management

As the provider of natural gas to more than 1 million customers in North Carolina, South Carolina and Tennessee, it’s our responsibility to provide safe and reliable energy to the communities we serve. This requires us to transport natural gas through a network of pipelines that may be located near or on property that belongs to natural gas customers as well as non-customers.

If you have any questions about pipeline safety or about Piedmont’s Pipeline Integrity Management Programs, please email us at
