TULSA, Okla., April 7, 2014 /PRNewswire/ -- ONEOK Partners, L.P. (NYSE: OKS) announced today that its subsidiary, Midwestern Gas Transmission Company, has filed an application with the Federal Energy Regulatory Commission (FERC) to enter into the pre-filing process for the proposed development of an approximately 15-mile natural gas pipeline lateral in Ohio and Muhlenberg Counties in Kentucky.

The proposed natural gas pipeline lateral would connect Midwestern Gas Transmission's existing natural gas transmission pipeline to a new, high-efficiency, natural gas-fired electric-power generation plant being constructed by the Tennessee Valley Authority (TVA) at its Paradise plant site in Muhlenberg County, Ky., that has an estimated maximum natural gas flow of 227,000 dekatherms per day.

Subject to FERC approval of the pre-filing application, ONEOK Partners will conduct stakeholder outreach for the proposed natural gas pipeline lateral, including a public open house in Ohio County, Ky., in May 2014. The construction schedule for the proposed natural gas pipeline lateral could include:


    --  Filing applicable permits with regulatory agencies in October 2014;
    --  Beginning construction in September 2015, pending regulatory approvals;
        and
    --  Placing the lateral in service September 2016.

The proposed natural gas pipeline lateral is subject to the execution of a precedent agreement with the TVA. Construction of the natural gas pipeline lateral is subject to FERC jurisdiction and would require the completion of an environmental assessment.

Midwestern Gas Transmission is an approximately 400-mile natural gas pipeline that provides bidirectional natural gas services to markets in Tennessee, Kentucky, Indiana, southern Illinois and the Chicago market hub.
