Who is TransCanada?
• A leading energy company focused on
natural gas transmission and power
services in North America
• More than 59,000 kilometers of steel
pipe ranging in size from 2” to 48” in
diameter, plus interests in 7800 kms
of natural gas pipelines
• Average daily volume of approximately
15 Bcf Natural Gas
• Keystone oil pipeline 1.1 million Bbl/d
• Interests in more than 11,800
megawatts of power – enough to meet
the needs of about 11 million average
households

TransCanada Transports Sweet Natural Gas
• Properties of Natural Gas
• Lighter than air; dissipates into the
atmosphere
• Non-toxic
• Highly flammable
• Colorless and odorless (likely has a
slight hydrocarbon smell from
processing)
6
Pipeline Pressures
• Typical pipelines pressures are
between 800 to 1,400 PSI
• Most of our Canadian Pipeline
System is regulated by the
National Energy Board (NEB)
7
Ground Disturbance
• Any work, operation or activity that results in a disturbance of
the earth including, without limitation, excavating, trenching,
pile driving, drilling, tunnelling, backfilling, blasting, topsoil
stripping, but does not include: disturbance of the earth to a
depth less than 300 mm (1 ft) that does not result in a
reduction of pipe cover less than that provided when the pipe
was installed.
8
Search Area
• This is the area 30m (100ft) from the edge of your proposed
ground disturbance. This area should be searched for all
buried facilities. Watch for visual signs.
11
One Call
As required by the National Energy
Board, a call needs to be placed at
least three full working days before
any ground disturbance (it is a free
service)
1-800-474-6886

Locate
• TransCanada field rep will:
• Call to confirm details of type of
work, location, etc…
• Will respond within one to two
days to provide locates where
required
• Determine a safe method for
heavy equipment to cross the
right-of-way
13
Zones
• Safety Zone or Control Zone – this is an area established by
regulators to provide protection of buried facilities and safety
of the public. Notifications are required prior to performing
any ground disturbance within this area.
• The Safety Zone:
• AUC – extends 30m (100ft) from the edge of the pipeline
• NEB – extends 30m (100ft) from the edge of the right-of-way
• New NEB damage prevention regulations should be same as
Alberta
15
Zones Continued
• Tolerance Zone:
• No mechanical excavation can take place within 15m (50ft) of a
pipeline prior to it being hand exposed or hydrovac’ed to confirm
location
• Hand Exposed Zone:
• Distance of 600mm (2ft) from the edge of pipeline where no
mechanical excavation may take place.
16
What to do if you contact a pipeline
• Immediately shut equipment
down and stop all work
• If there is damage clear the area
and keep public out
• Call the pipeline owner and
report damage
• Call BC One Call and report the
damage
• If there is a leak call 911

QUESTIONS?
Pipelines are the safest method of transporting the huge volumes of
natural gas that must be moved throughout North America every day.
To keep our system safe, we rely on our neighbors and contractors to
be our partners in safety.
