There are 500,000 kilometers of natural gas transmission pipelines across North America with approximately 45,000 kilometres running through Canada in both urban and rural areas. More than 5 million homes and business across Canada safely use natural gas for heating and other needs. Natural gas is the source of heating for 48% of Canadian homes, 51% of industry and 39% of commercial businesses.
The design and construction of the Brunswick Pipeline and all transmission pipelines in Canada are guided by regulations set by the National Energy Board-Office national de l’énergie/ (NEB) and the Canada Standards Association/Normes CSA (CSA). These standards regulate operating pressures, pipe wall thickness, protective pipe coatings, depth of burial, public safety and system integrity management, and are considered among the highest industry standards in the world.
Emera New Brunswick, owner of the Brunswick Pipeline, prides itself on safety measures in construction and operations that meet or exceed federal regulations, which are considered among the highest industry standards in the world. For example:
- All steel was manufactured to CSA standards.
- The outside of the steel pipe is coated with a protective epoxy coating to protect against rust before being installed.
- The inside of the pipe is also coated to protect it against rust.
- Each weld was tested by non-destructive methods – x-ray or ultrasonic – to ensure pipe joints met required specifications.
- The entire pipeline underwent and passed a strength and integrity pressure-test before being passed for operation. This hydrostatic testing was done by filling the pipeline with water and raising its pressure above the intended operating pressure.
- In service, the computerized control systems are monitored to measure pressures and gas flow 24 hours each day, 7 days a week.
- Gas Control staff have the ability to open and close system valves remotely, to isolate gas flow from a pipeline section if it is required.
- We actively conduct a “Call Before You Dig” program for contractors.
- We regularly meet and train with local emergency respnders.
- We conduct regular aerial and foot patrols of the Brunswick Pipeline easement.
