NKY Gate Enhancement Project

PROPOSED PROJECT SCOPE

The proposed Project scope includes replacing and upgrading 51.5 miles of existing 20-, 24- and 26-inch pipeline installed in the 1950’s with 29.2 miles of new 30- and 36-inch pipeline, in addition to modifying and upgrading existing meter stations across Campbell, Pendleton, Bracken and Nicholas Counties. Once completed, the Project will increase reliability and improve deliveries to facilitate the growing demand for natural gas in the Northern Kentucky and Southern Ohio regions.

The Project consists of:

• Installation of approximately 24.2 miles of new 36-inch steel coated pipeline in Campbell, Pendleton and Bracken Counties in Kentucky.
• Installation of new 36-inch launcher/receivers at each end at Foster Station and near the Ohio River.
• Installation of four new 36-inch mainline valves.
• Installation of a five mile, 30-inch pipeline to connect two existing segments of the EM-7 pipeline between Carlisle Station and VS-215 Station in Nicholas County, Kentucky, effectively bridging a gap in the current EM-7 system. The Lift and Lay method of construction will be utilized within Columbia’s existing easements, where possible.
• Multiple existing meter stations will be modified and upgraded in Campbell, Menifee, Bracken and Pendleton Counties in Kentucky.
• A majority of the existing 51.5-miles of 20-, 24- and 26-inch KOT pipeline is to be abandoned-in-place. The removal of approximately five miles of existing 14-inch EKY pipeline between Carlisle Station and VS-215 will be abandoned and removed via Lift and Lay construction. To ensure continued natural gas deliveries and avoid service disruptions, all existing pipelines will remain in service until after the new 36- and 30-inch pipelines are installed and in-service.
