Review of Abandonment Cost Estimates (ACE) for Group 2 Pipeline Companies (Group 2 ACE Review)

On 8 June 2018, the National Energy Board (NEB or Board) issued a letter to all Group 2 pipeline companies informing them that the Board would commence its review of their ACE. The Board directed all Group 2 pipeline companies to file for approval by noon, 20 July 2018:

• a copy of the last approved ACE (blacklined to show changes) and a clean copy of the updated ACE for approval, using the tables and instructions provided in the attached Appendix III;

or

• the information found in Appendix II of the 8 June 2018 letter which the Board would use to determine the ACE amounts.

On 6 November 2018, the Board issued a letter to Group 2 Pipeline Companies that had not filed an updated ACE. The companies identified in the letter were to file their ACE by 20 November 2018.

Late submissions in response to the 6 November 2018 letter

For those Group 2 pipeline companies that filed their updated ACE late in accordance with the Board’s 6 November 2018, the Board is presently reviewing these filings and therefore, the Board’s decisions regarding to those Group 2 pipeline companies’ ACE filings are not included in this letter.
