Trunkline Gas Co. LLC applied Feb. 23 at the Federal Energy Regulatory Commission for authorization to make system modifications necessary to enable it to provide 750,000 dekatherms per day (Dth/d) of north-to-south firm transportation service within Zones 1B and 1A of its pipeline system.
The proposed facilities will allow the pipeline to meet new demand for north-to-south transportation of production to the Midwest and Gulf Coast markets, while maintaining its existing firm service obligations from south-to-north contract paths. The proposal is referred to as the “Trunkline Backhaul Project.”
The project will utilize certain existing pipelines and compressor stations that are already certificated and in-service, and will only require the specified changes to Trunkline’s system, including: the reconfiguration of certain compressor station piping at the existing Johnsonville, Joppa, Dyersburg and Independence Compressor Stations located in three states (Illinois, Tennessee and Mississippi); and the modification of the existing interconnect with Panhandle Eastern Pipe Line Co. LP located near Bourbon, Illinois.
The requested facility modifications are being designed primarily to meet the demand for additional transportation capacity to transport natural gas supplies from the Marcellus and Utica shale production regions to Midwest and Gulf Coast markets. Trunkline asked that the commission issue the requested certificate of public convenience and necessity by November 2015.
Trunkline’s transmission system extends from its historical sources of supply in the states of Texas and Louisiana, through Arkansas, Mississippi, Tennessee, Kentucky and Illinois, to a principal terminus at the Indiana-Michigan state line near Elkhart, Indiana.
Trunkline has executed a precedent agreement with Rover Pipeline LLC at a rate that is designed to fully recover the cost of service associated with the backhaul project.
