ONEOK Partners Accepts FERC Certificate for Guardian Pipeline Expansion and Extension Project

TULSA, Okla., Jan. 3 /PRNewswire-FirstCall/ — ONEOK Partners, L.P. (NYSE:OKS) announced today that one of its subsidiaries, Guardian Pipeline, L.L.C., accepted the certificate of public convenience and necessity issued by the Federal Energy Regulatory Commission (FERC) on Dec. 14, 2007, for its Guardian Pipeline expansion and extension project. The certificate authorizes ONEOK Partners to construct, install and operate approximately 120 miles of a 30- and 20-inch natural gas transportation pipeline with a capacity to transport 537,200 dekatherms per day (Dth/d) of natural gas north from Ixonia, Wis., to near Green Bay, Wis.


“This expansion will meet the needs for additional natural gas supplies that are important to eastern Wisconsin’s economic health and long-term competitiveness,” said Pierce Norton, ONEOK Partners executive vice president of natural gas. “The Guardian project expands our existing natural gas pipeline footprint and is a part of the partnership’s overall growth strategy to invest more than $1.6 billion in internally generated growth projects through 2009, creating additional value for our customers and unitholders.”


The project is an extension and expansion of Guardian Pipeline, a 143-mile interstate pipeline system between Chicago and Ixonia, Wis. The 120-mile pipeline extension and expansion is anchored by 15-year agreements with Wisconsin Public Service Corporation and two subsidiaries of We Energies.


The Public Service Commission of Wisconsin has given approval to the utilities to tie into the pipeline, which will provide needed additional natural gas transmission capacity in eastern Wisconsin. In addition, the FERC record indicates that the project has the support of at least 85 separate entities, including trade unions, Realtor associations, hospitals and health care groups, colleges and universities, businesses and chambers of commerce and utilities.


Construction on the $260 million extension and expansion project, the cost of which excludes allowance for funds used during construction (AFUDC), is anticipated to begin in the first quarter of 2008 and is projected to be in service in the fourth quarter of 2008.
