The public input session is scheduled for 3 November 2009 and is a component of the Public Utilities Commission hearing on the Keystone pipeline permit application.

The proposed pipeline route in South Dakota has an estimated length of 505 km and will cross through the counties of Harding, Butte, Perkins, Meade, Pennington, Haakon, Jones, Lyman and Tripp.

The Keystone Pipeline project combines both the new construction of pipeline and the conversion of an existing pipeline from natural gas to oil service.

The 3,456 km Keystone Pipeline will provide a secure and reliable supply of Canadian crude oil to meet the growing demand by United States refineries and markets. Approximately 2,219 km of new pipeline is to be constructed in the US. The Canadian portion of the project includes the construction of approximately 373 km of new pipeline and the conversion of approximately 864 km of existing TransCanada pipeline from natural gas to crude oil transmission.
