PONCA CITY, Okla. (AP) -- A Canadian company plans to spend $2.1-billion to build an oil pipeline that would run from the Canadian province of Alberta to the north-central Oklahoma town of Cushing.


An official from TransCanada's Keystone Project Team said Tuesday that the proposed 30-inch pipeline would be buried a minimum of four feet underground. It would enter Oklahoma in Kay County, on the state's border with Kansas.


The pipeline would go through a pump station to be located near Newkirk and into Ponca City and a terminal there owned by ConocoPhillips.


The pipeline then would travel into Noble and Payne counties before ending at a terminal in Cushing.


The company hopes to have the project approved and licensed by the end of 2007 and to construct the pipeline in 2008 and 2009.
