The Lakehead Part~rship is owned by Enbridge Energy Partners, L.P. The Lskehead Partnenth/p has undertaken this depreciation s/udy to d e t e ~ whether the current depreclation rates need to be revised. To asmst in this pmcem, the Lakehead PartDecshlp ensaged Gannett Flemins, Inc. as consultants to assess the composite remaining service lives of the Lakehead Partnership's carrier property and present the company with proposed delxeciafioa r a t ~ A copy of Gannett Flenfing's report is included in this filin8. The resultsofthe depreclafion study dic*ate that changes to previously approved depreciation reds be proposed for each accoem for ratemak/n8 purpoee~ These proposed depreciation rote changes represent an overall decrease in the provision for depreciation expenae of approximately 14%, due to a change in the truncation pe~od used f~,om26 to 30 years, and will not affect the Lakehead PartnemHp's exi~n 8 tariff rates. In the last depreciation study by the l.akehead Partnership (Docket Number DO99-3-000), a truncation period of 26 years was used. However, with the developn~nt of the Western Canadian oil sands and our continued level of maintenance and capital eahanccment of the system, we believe that the Lskehead Pannership's current effective composite rema/nin8 life of 19 years is too conservative. Using a 30-year truncation period will increase the Lakehead Pm'mership's composite remaining life to approximately 24 years. Therefore, we belive that a tnu~ation perlod of 30 years is more reasonable and we r e q ~ ~ ~ proposed depreciation rates be made effective m of January 1, 2003.
