Trans Mountain Pipeline – 60 Years of History
TRANS MOUNTAIN PIPELINE TODAY
Trans Mountain Pipeline • In operation since 1953 • 1,150 km from Edmonton to Burnaby • Transports refined products and crude oils: conventional, synthetic and dilbit • Regulated by the NEB • Last expansion completed in 2008 – Anchor Loop • Current capacity: 300,000 bpd Existing relationships along the Right-of-Way

TRANS MOUNTAIN EXPANSION PROJECT OVERVIEW
Proposed Scope of Expansion Project • Jan. 10, 2013: Scope update announced • Based on revised 15- and 20-year commitments from shippers to use the line • The proposed expansion to increase capacity to 890,000 barrels per day • Projected capital cost is approximately $5.4 billion
Proposed Scope of Expansion Project • Result: a dual-line operation – twinned pipeline (approximately 980 km of new pipeline) with: – Existing line for lighter products – The proposed new line for heavier oils • 36-inch pipeline diameter • 11 new pump stations for a total of 35 pump stations along the route
Proposed Scope of Expansion project • Estimated 21 new storage tanks at existing facilities in Edmonton, Sumas and Burnaby for a total of 61 tanks along the route • Three loading berths at the Westridge Marine Terminal

MARINE
Marine Traffic Current traffic in Port Metro Vancouver related to Westridge Marine Terminal operations Current Estimated with Proposed Trans Mountain Expansion Project 8 vessels per month 37 vessels per month • Jet fuel barges: 1 • Jet fuel barges: 1 • Tankers: 5 • Tankers: 34 • Crude oil barges: 2 • Crude oil barges: 2 • Currently: less than 3% of marine traffic in Port Metro Vancouver Should the proposed expansion be approved, the number of vessels, including tankers and barges, being loaded at the Westridge Marine Terminal could increase to approximately 37 per month (34 of which could be tankers) in 2017, or about 14% of today’s total Port Metro Vancouver vessel traffic.
TECHNICAL CHALLENGES
ROUTING, CONSTRUCTION AND GEOTECHNICAL
Routing • Key criteria in route selection – Follow existing 24” TMPL – Parallel other linear disturbances e.g. road, rail and power lines – Avoid environmentally/geotechnically sensitive areas where possible – Minimize number of major rivers that have to be crossed • Issues faced during routing – Hwy. 16, 5 and 1 were not there when pipeline was built in 1952/53 • Previous road expansions have left many pinch points between existing RoW, road, rail, mountainsides and rivers – Property development between Langley and Burnaby
Routing • For example…
Routing • Show map from Chilliwack to Burnaby • Close up map of Burnaby
Routing • Show map from Chilliwack to Burnaby • Close up map of Burnaby
Routing Outcome • TMEP study corridor (Facilities Application will be submitted to NEB late 2013) – 70% adjacent to or in existing TMPL easement (typically 18 m wide) – 20% adjacent to other linear disturbances – 10% greenfield • Uncertainty about 10% of the route, assessing alternative routes due to: – Landowner concerns – Aboriginal or Stakeholder concerns – Environmental reasons
Construction • Rural vs. urban pipelining • Mountainous terrain – Blasting, backfill and pipe protection procedures, remediation – Will draw extensively on Anchor Loop experience

Stream Restoration
Geotechnical • Avoid areas prone to ground movement – Detailed seismic study underway – Complete geohazard inventory developed – Leverage 60 year operating history and detailed natural hazard database • River crossing design – HDD or micro-tunneling vs. conventional “open cut”
SYSTEM HYDRAULICS
System Hydraulics • New 36” pipeline loop (Line 2) – Sustainable annual average pipeline capacity of 540,000 bpd • Based on an assumed slate of heavy crude oils • Existing 24”/30” pipeline (Line 1) – Sustainable average annual pipeline capacity of 350,000 bpd • Based on an assumed slate of light crude oils and refined products • Burnaby to Westridge – Two new 30” pipelines 700,000 bpd – Existing 24” pipeline 500,000 – 700,000 bpd
System Hydraulics • Steady state hydraulic studies completed to verify preliminary results • Pressure surge or transient studies needed to ensure adequate overpressure protection – Pressure surges must be < 110% of the MOP
Liquid Pipeline Operations • Product quality – Depends on flow regime – laminar vs. turbulent – Batches used to be physically separated • Slack flow – Static pressure = Dynamic pressure – Formation of vapour space

INTEGRITY MANAGEMENT
Integrity Management • Facilities and pipeline undergo hazard identification process and incorporate safeguards into design • If design fails, spills are prevented and/or mitigated by procedures, inspection and detection
Design features • Facilities – Materials, site selection, earthworks, containment • Pipeline – Pipe grade and wall thickness, depth of cover, routing and valve spacing/automation
