California Natural Gas Replacement Project

Project Background

Duke Energy will be replacing an existing natural gas pipeline in the southeast Cincinnati area starting in 2023. This infrastructure has been in service since the 1960s.

Known as the California Replacement Project, this work is required under recent changes to federal regulations titled “Pipeline Safety: Safety of Gas Transmission Pipelines: MAOP Reconfirmation, Expansion of Assessment Requirements, and Other Related Amendments.” This is commonly referred to as the “Mega Rule.”

In total, about 3.9 miles of infrastructure will be installed and one new regulator station will be replaced. The new upgraded infrastructure will start near Coney Island, then travel through California and continue north near Kellogg Avenue and end near Salem Road in Cincinnati. There is also a section along Beechmont Avenue near Lunken Airport that will be replaced as part of this project.
