Safety in the numbers Working Safely Around Pipelines

1. Safety in the numbersWorking Safely Around Pipelines Dig Safe BC! Workshop: March 2010

2. 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

4. TransCanada Pipelines BC System

5. 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

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

19. 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. Remember Work Safely Around Pipelines “It's Your Call” Be aware, take care, call for safety
