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
• peration – 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

Application Preparation 1.5 years

Commercial (Tolling) Approvals

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

• Jet fuel barges: 1
• Tankers: 5
• Crude oil barges: 2
• Currently: less than 3% of marine

traffic in Port Metro Vancouver 37 vessels per month

• Jet fuel barges: 1
• Tankers: 34
• Crude oil barges: 2

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,

• r 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

FACILITIES

Burnaby Terminal Overview

Existing Planned

• 13 tanks
• 14 new tanks
• 1.6 million bbl capacity
• 3.9 million bbl incremental

capacity

• 24-inch pipeline entering from

southeast

• New 36 inch pipeline entering

Burnaby Terminal – Existing & Planned

Westridge Marine Terminal Overview

Existing Planned

• Dock capable of loading 1

Aframax-sizing or smaller vessel

• One new dock complex (2 docks

with 3 berths) each capable of loading vessels the same size we load today

• Berth to be deactivated +

demolished after new berths enter service.

• Aframax vessels subject to same

restrictions, including being loaded at 85% capacity, 550,00 bbls.

• 4 PMV designated anchorage

locations

• No plans for additional anchorage

locations

• One 24-inch pipe from Burnaby

Terminal to remain in service

• Two new 30-inch delivery lines

from Burnaby Terminal

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
• f cover, routing and valve spacing/automation

Integrity Management

• Misinformation regarding properties of diluted

bitumen (“dilbit”)

• Similar to conventional heavy crude oils
• Must meet NEB approved TMPL tariff

specifications:

– Maximum temperature of 38 C – Maximum density of 940 kg/m3 – Maximum viscosity of 350 cSt at Reference Temperature – Maximum impurities (basic sediment and water) of 0.5% of volume – Maximum Reid Vapour Pressure of 103 kPa

Integrity Management

• Multiple studies on dilbit characteristics

– National Research Council – Effects of Diluted Bitumen on Crude Oil Transmission Pipelines – CEPA – Report on Dilbit Corrosivity – Natural Resources Canada (NRCan) – Bitumen-Derived Crude and Corrosivity – Alberta Innovates – Comparison of the Corrosivity of Dilbit and Conventional Crude – All are linked at http://www.transmountain.com/diluted-bitumen- info

AUTOMATION, MEASUREMENT AND LEAK DETECTION

Automation and Measurement

• SCADA (supervisory control and data

acquisition) is used to monitor pipeline process variables

– Pressure – Flow – Temperature – Density – Viscosity – Colour

Automation and Measurement

• SCADA system will be upgraded with satellite

communications from every remote site

• Pressure, temperature and flow rate

instrumentation is needed for computer-based leak detection systems

Leak Detection

• Current computer-based models

– Real Time Transient Models – Mass Balance Systems

• External leak detection systems
• Cable-based technologies

– Distributed Temperature Sensing – Hydrocarbon Sensing Cables – Vapour Sensing Tubes – Distributed Acoustic Systems

• Aerial-based technologies
