Piedmont is working hard to deliver safe and reliable natural gas throughout our Tennessee region. As part of this commitment, we are working diligently every day on the safe operation, design and installation of our natural gas transmission system and local distribution networks.

Project Overview

In response to the increased demand for natural gas in the east Nashville area near downtown, Piedmont Natural Gas plans to upgrade and replace our distribution infrastructure from Trinity Lane to Cowan Street. Parts of this infrastructure have been in service since the 1950s.

We will replace approximately 2.4 miles of existing infrastructure and build a new pressure-regulating station to maintain compliance with federal pipeline regulations, address increased demand and continue providing safe, affordable and reliable natural gas service to the area.

We have met with local officials, landowners and other stakeholders to hear viewpoints from across our community. Our goal is to take our neighbors’ concerns into consideration while meeting our customers’ needs.

Our goal is to minimize the impact of our construction activities on property owners, the community and the environment. We take all factors into consideration, including environmentally sensitive areas, impacts on rare plant and animal species and landowner concerns and requests.

We realize construction can be disruptive and challenging for the community, but we are committed to making the process as smooth as possible. Here’s what we have been doing:

  • Communicating with property owners to negotiate easements and discuss expectations during construction and restoration.
  • Being mindful of pedestrian and traffic safety during construction.
  • As we near the completion of construction, any disturbed right of way will be stabilized then restored as closely as possible to their preexisting condition.

We will notify property owners in the replacement area of upcoming field survey work via postcard or letter.

Key Benefits

  • Replacing/Upgrading existing natural gas infrastructure
    Current natural gas infrastructure will be replaced with a modern distribution system.

  • Serving our customers
    The upgraded infrastructure will allow us to continue to provide safe and reliable natural gas service to Nashville customers for decades to come.

Safety and Environmental Protection

Piedmont’s No. 1 priority is the safety of our natural gas infrastructure, our communities and our employees. We build multiple and redundant safety systems into all aspects of our natural gas infrastructure.

Piedmont is committed to protecting significant cultural sites, environmentally sensitive areas and endangered species. We work with appropriate federal and state agencies and comply with applicable laws and regulations. Beyond that, Piedmont has its own standards designed to minimize the impact of our construction activities on surrounding areas.
