ITEM 8.01         OTHER MATERIAL EVENTS.

         We are providing updated information regarding (1) the sale of two of
our general partners and a service provider to us, (2) updated information
related to the Enron Corp. Cash Balance Plan (the "Cash Balance Plan"), and (3)
Northern Border Pipeline Company's ("Northern Border Pipeline") announcement of
an expansion project and its recontracting efforts.

Sale of General Partners and Service Provider

         In June 2004, Enron Corp. ("Enron") announced that it had reached an
agreement with CCE Holdings, LLC ("CCE Holdings"), a joint venture of Southern
Union Company and GE Commercial Finance's Energy Financial Services, for the
sale of CrossCountry Energy, LLC ("CrossCountry"). CrossCountry owns Northern
Plains Natural Gas Company and Pan Border Gas Company, two of our general
partners. CrossCountry also owns NBP Services Corporation, which provides
administrative services to us.

         On September 1, 2004, Enron announced that it reached an amended
agreement for the sale of CrossCountry to CCE Holdings ("CCE Holdings
Agreement"). On September 10, 2004, the Bankruptcy Court issued an order (the
"Order") approving the CCE Holding Agreement, between CCE Holdings and Enron.
The acquisition is subject to satisfaction of certain approvals and other
closing conditions and is expected to close no later than mid-December 2004.

         On September 16, Southern Union Company and ONEOK, Inc. each announced
that ONEOK has entered into an agreement ("ONEOK Agreement") to purchase
Northern Plains Natural Gas Company, Pan Border Gas Company and NBP Services
Corporation (collectively, the "Transfer Group Companies") from CCE Holdings.
This acquisition, which is subject to satisfaction of certain approvals and
other closing conditions, is expected to close concurrently with the CCE
Holdings purchase of CrossCountry.

         Under the CCE Holdings Agreement, Enron has agreed to extend certain of
the terms of the transition services agreement and transition services
supplemental agreement between CrossCountry and Enron (together the "TSA") for a
period of six months from the closing date. Under the ONEOK Agreement, CCE
Holdings and ONEOK have agreed to use reasonable commercial efforts to
memorialize a transition services agreement referred to as the "Northern Border
Transition Services Agreement" covering certain transition services by and among
ONEOK, the Transfer Group Companies, CCE Holdings and Enron. There is no
obligation on the part of Enron to enter into such arrangement, and there can be
no assurance that any such agreement will be entered into by Enron. In the event
the Northern Border Transition Services Agreement is not entered into, then the
ONEOK Agreement provides that certain transition services will be provided to
the parties on substantially the same basis as provided prior to closing. We
have not been advised of nor evaluated the impacts of the transition on us. Once
Northern Plains and NBP Services advises us of the extent of the transition
services required, we can assess any impacts to our resources, systems and
operations.



Additionally, since we do not know which systems or services of Enron,
CrossCountry, CCE Holdings, or ONEOK will be utilized for us, assessment and
implementation of controls, as well as documentation and testing, of any new
processes or systems that require conversion before year-end may not be possible
and may affect management's report on internal controls and procedures required
pursuant to Section 404 of the Sarbanes-Oxley Act of 2002.

Cash Balance Plan

         In the Order, Enron was authorized to enter into an escrow agreement
with CCE Holdings and Pension Benefit Guaranty Corporation ("PBGC"). Upon
closing, Enron will deposit the amount of $321.8 million to an escrow account,
which is intended to ensure that none of CCE Holdings or its affiliates are
exposed to liability to the PBGC under Title IV of the Employee Retirement
Income Security Act of 1974, as amended, for which CCE Holdings may otherwise be
indemnified pursuant to the CCE Holdings Agreement. In addition, the form of
escrow agreement approved pursuant to the Order provides that, under certain
circumstances and upon approval by or notice to the parties to the escrow
agreement, some or all of the funds placed in escrow may be paid directly in
respect of the Cash Balance Plan or to the PBGC. However, the Order also
provides that PBGC retains any rights or claims it may have against Northern
Plains and Pan Border.

         Under both the CCE Holdings Agreement and the ONEOK Agreement, none of
Northern Plains, NBP Services or us will be required to contribute to or
otherwise be liable for any contributions to Enron in connection with the Cash
Balance Plan. The purchase price under the agreements will be deemed to include
all contributions which otherwise would have been allocable to Northern Plains
and NBP Services from Enron.

      While the final amounts chargeable to us under the operating agreements
and administrative services agreement for the termination of the Cash Balance
Plan cannot be determined at this time, we continue to believe the ultimate
settlement of this matter will not have a material adverse effect on our results
of operations.

Northern Border Pipeline Expansion Project and Sale of Capacity

Attached as Exhibit 99.1 is a copy of Northern Border Pipeline's press release,
dated September 23, 2004, which announced that sufficient customer support was
received to proceed with a proposed expansion of its pipeline system into the
Chicago market area. The "Chicago Expansion III Project" would expand capacity
of Northern Border Pipeline from Harper, Iowa to Chicago by approximately 130
million cubic feet per day or approximately 15 percent and is being done to help
meet additional demand on this segment of the pipeline system. The project would
add a 16,000 horsepower compressor in Iowa and make minor modifications to
existing facilities. Capital costs are estimated to be approximately $20 million
and the target in-service date



is Spring 2006. Construction is subject to approval by the Federal Energy
Regulatory Commission.

Northern Border Pipeline also announced that additional capacity on its upstream
segments from Port of Morgan, Montana to Harper available November 1, 2004 had
been recontracted. The capacity commitments are at the maximum transportation
rates with terms of five to six months.

This current report 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 believes that these
expectations are based on reasonable assumptions, there is 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
include developments in Enron's voluntary petition for bankruptcy, the closing
of the sale of CrossCountry Energy to CCE Holdings and the latter's subsequent
sale to ONEOK, and the receipt of necessary regulatory and governmental
approvals for the Chicago III Project.
