TransCanada Pipeline USA recently filed a Federal Energy Regulatory Commission (FERC) permit application for the proposed Pathfinder Pipeline Project and for Northern Border Pipeline Co.’s Bison Pipeline Project. A TransCanada subsidiary recently acquired Bison Pipeline LCC from Northern Border.
The proposed Pathfinder project is an approximately 673-mile, 36-inch and
42-inch diameter interstate pipeline that would transport natural gas northeast
from Meeker, Colo., through Montana to the Northern Border pipeline system in
The project would consist of four segments – the construction of 130 miles of
pipeline from an existing hub near Meeker to Wamsutter Wyo., followed by 236 miles
of pipeline from Wamsutter to Dead Horse, Wyo., 297 miles of pipeline from Dead
Horse to Morton County, N.D., and 11 miles of lateral supply pipeline near
Officials say the Pathfinder pipeline would have an initial capacity to move about
1.1 billion cubic feet of natural gas per day, with an ultimate capacity of
about 1.6 billion cubic feet per day. Gas would be delivered through the
pipeline into the Ventura, Calif., and Chicago-area markets, according to
The proposed 289-mile, 24-inch diameter Bison Pipeline system would extend from
natural gas gathering facilities located in the Powder River Basin around Dead
Horse and Fort Union.
The Pipeline also would connect with the Northern Border Pipeline system in North
Dakota. The 1,249-mile Northern Border Pipeline transports natural gas from the
Montana-Canada border to markets in the Midwest.
The initial capacity of the Bison Pipeline project is estimated to be about 400
million cubic feet per day, with a maximum capacity of 600 million cubic feet
FERC officials say the entire route of the Bison Pipeline is identical to that
of the corresponding portion of the Pathfinder Pipeline.
The notice said TransCanada is proposing to build either Pathfinder or Bison,
and once the company determines which of the two projects it will pursue,
TransCanada will file a request with the FERC to discontinue review of the
The proposed pipelines aim to keep pace with drilling in the Rockies, where
natural gas production is pushing against available pipeline export capacity,
keeping the price of the region’s natural gas well below the national average
in recent years.
FERC officials say both projects have an estimated in-service date of late
