US-based Duke Energy has modified its plan for the Central Corridor Pipeline Extension Project and submitted a proposal to the Ohio Power Siting Board (OPSB) to construct a smaller natural gas pipeline that operates with less pressure.
The company submitted two proposed pipeline routes to OPSB for consideration.
In its application, a preferred route has been identified, which will be the eastern route and would terminate in Fairfax.
Duke Energy was also required to submit an alternate route.
The final route will be decided by the OPSB, which will also suggest modifications.
With a 20-inch diameter, the proposed 12-mile to 14-mile pipeline will operate at approximately 400 pounds per square inch and enable Duke Energy to retire aging propane peaking plants.

Duke Energy Ohio and Kentucky president Jim Henning said: "We have been listening to feedback from our customers, neighbours and community leaders.
"The reduction in size and pressure of the proposed natural gas pipeline is a direct result of this feedback.
"This new pipeline is critical for us to continue safely meeting the natural gas needs of nearly two million people in this region, both today and for generations to come."
Duke Energy currently operates more than 14,000 miles of natural gas pipelines and service lines in Ohio and Kentucky.
