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 Pipelines BC System

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.

9

Marked Crossing

• Pipeline ROW crossings are clearly marked

10

Other Markers

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

12

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

14

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

17

How to contact TransCanada

Non Emergency -

Contact TransCanada

through the Regional

Offices or directly to our

Head Offices in Calgary

18

We need your assistance to...

• Remember to call the BC 1

Call - it is a free service

• Remember to contact the

pipeline company

• Remember to always put

safety first!

• Remember to watch for the

visual clues that indicate

you are near an

underground facility

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.
