NORTHERN BORDER PARTNERS ANNOUNCES AMENDMENT TO PROJECT 2000 APPLICATION TO MEET FERC POLICY

OMAHA – Northern Border Partners, L.P. announced today that Northern Border Pipeline Company has amended the application filed on Oct. 16, 1998 with the Federal Energy Regulatory Commission (FERC) for its Project 2000 facilities. The amendment conforms to the FERC’s Sept. 15, 1999 Statement of Policy in that the revised project requires no subsidy from existing customers. The project’s capacity is fully subscribed on a long-term basis under binding precedent agreements.

“Project 2000 is designed to strategically position Northern Border Pipeline to move natural gas east of Chicago and place our shippers in direct contact with the northern Indiana industrial zone, including providing an interconnect with Northern Indiana Public Service Company,” said Larry DeRoin, chairman, Partnership Policy Committee and CEO, Northern Border Partners, L.P. “This project continues Northern Border’s planned growth into new and diversified markets, including the United States’ largest steel mills in northern Indiana. We are eager to provide transportation services for low-cost and reliable natural gas to this industry.”

In the amended application, Northern Border Pipeline proposes to install approximately 35 miles of 30-inch pipe; uprate the horsepower at existing Iowa compressor facilities; and install a new compressor facility in Bureau County, Illinois. Revised capital expenditures are estimated to be nearly $95 million. Northern Border Pipeline is seeking FERC approval by March 15, 2000.

Northern Border Pipeline Company is a general partnership which owns and operates a 1, 214-mile large diameter pipeline that transports about 24 percent of all Canadian gas imported into the United States. Northern Border Partners, L.P. owns a 70 percent general partner interest in Northern Border Pipeline. The remaining 30 percent interest in Northern Border Pipeline is owned by TC PipeLines, LP. Northern Border Partners, L.P. common units are listed on the New York Stock Exchange under the symbol “NBP.”

This press release includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Although Northern Border Partners, L.P. believes that its expectations are based on reasonable assumptions, it can give no assurance that such expectations will be achieved. Important factors that could cause actual results to differ materially from those in the forward looking statements herein include, but are not limited to, political and regulatory developments that impact Federal Energy Regulatory Commission, Northern Border Pipeline’s success in sustaining its positions in such proceedings or the success of intervenors in opposing Northern Border Pipeline’s positions, political and regulatory developments in Canada and conditions of the capital markets during the periods covered by the forward looking statements.
