The certificate authorizes Oneok to construct, install and operate approximately 120 miles of pipeline for natural gas transportation with a capacity to transport 537,200 dekatherms per day from Ixonia to Green Bay in Wisconsin.

The 120-mile pipeline extension and expansion is anchored by 15-year agreements with the Wisconsin Public Service Corporation and two subsidiaries of multi-utility We Energies. Construction on the $260 million project is anticipated to begin in the first quarter of 2008 and is projected to be in service in the fourth quarter of 2008.

The Public Service Commission of Wisconsin has given approval to utilities to tie into the pipeline, which will provide additional natural gas transmission capacity in eastern Wisconsin.
