DECISION AND RATE ORDER
Union Gas Limited (“Union”) filed an Application dated September 15, 2010 with the
Ontario Energy Board (the “Board”) under section 36 of the Ontario Energy Board Act,
1998, S.O. c.15, Sched. B, as amended, for an order of the Board approving or fixing rates for the distribution, transmission, and storage of natural gas, effective January 1,
2011. The Board assigned docket number EB-2010-0148 to the Application and issued a Notice of Application on September 22, 2010. Union’s Application was pursuant to the annual rate setting incentive regulation mechanism approved by the Board in the EB-
2007-0606 proceeding.

- 2 Ontario Energy Board
On September 23, 2010 Union filed evidence and a draft rate order in support of its
Application. On October 20, 2010 the Board issued Procedural Order No.1 which included the timeline for the filing of interrogatories and interrogatory responses, the convening of a Settlement Conference on November 8, 2010, and the hearing of any
Settlement Proposal filed by the parties on November 18, 2010.
Following the Settlement Conference held on November 8, 2010, a Settlement
Agreement was filed with the Board on November 11, 2010. The Settlement Agreement indicated that a complete settlement was reached on all issues by all parties who took part in the Settlement Conference with the exception of TransCanada Energy who took no position on all issues.
By Procedural Order No. 2 dated November 15, 2010, the Board cancelled the
November 18, 2010 oral hearing to review the Settlement Agreement. The Board in its
Decision and Order, dated November 16, 2010, accepted the Settlement Agreement and ordered Union to file a Draft Rate Order reflecting the Settlement Agreement.
Parties were given five working days to make comments on the Draft Rate Order. One letter of comment was received from London Property Management Association indicating that the Draft Rate Order accurately reflected the Settlement Agreement. No other submissions were filed pertaining to the Draft Rate Order.
This Rate Order represents the implementation in rates of the amounts that were approved by the Board in its November 16, 2010 Decision and Order. The Board accepts the rates as filed based on the supporting working papers and schedules.
THE BOARD THEREFORE ORDERS THAT:
1. The rate changes set out in Appendix “A” and the rate schedules set out in
Appendix “B” are approved effective January 1, 2011. Union shall implement these rates on the first billing cycle on or after January 1, 2011.
2. The Monthly Charge in Rate M1 and Rate 01 shall increase from $19 to $20 effective January 1, 2011.

- 3 Ontario Energy Board
3. In accordance with the EB-2007-0606 Decision dated July 31, 2008, Union will pass on to ratepayers through a "Z factor" adjustment 50% of the tax reductions that will be applicable to Union during the Incentive Regulation term.
4. The rates pursuant to all contracts for interruptible service under Rates 25, M5A,
M7, and T1 shall be adjusted by the amounts set out in Appendix "C". Union shall implement 2010 changes in rates on the first billing cycle after January 1, 2011.
5. Union shall charge the fees as set out in Appendix "E” for non-energy charges.

Dear Mr. Sondergard:
TransCanada PipeLines Limited (TransCanada) - Union Dawn Receipt Point
Surcharge Application
On 13 August 2010, TransCanada filed an application with the National Energy Board requesting approval of:
• the methodology for establishing the recovery of the cost of the Union Gas Service Contract and the associated fuel requirement;
• the creation of the Union Dawn Receipt Point Surcharge Deferral Account;
• the resulting amendments to the Tariff; and
• the resulting amendments to the Mainline Toll Design Schedules, including the level of the
Union Dawn Receipt Point Surcharge, effective 1 November 2010.
The Board notes the application was supported by unopposed Tolls Task Force Resolution
01.2010: Dawn to Dawn (TCPL) Service (User Pay).
The Board has examined TransCanada’s application and approves the application as filed.
TransCanada is directed to serve a copy of this letter on its Tolls Task Force Members, its
Mainline shippers, and other interested persons.
Yours truly,
Anne-Marie Erickson
Secretary of the Board
