2017 NGTL System Expansion Project

About the Proposal

NOVA Gas Transmission Ltd. (NGTL) filed its regulatory application for the 2017 NGTL System Expansion Project (Project) on 31 March 2015. NGTL, a wholly owned subsidiary of TransCanada PipeLines Limited (TransCanada), proposes to construct and operate new pipeline facilities in Alberta to receive and deliver sweet natural gas as part of the existing NGTL System.

The Project as proposed would include:

1.  230 km of pipeline ranging from 610 mm (Nominal Pipe Size (NPS) 24) to 1219 mm (NPS 48) outside diameter (OD) in five separate sections in Northern Alberta:

  • Northwest Mainline Loop – Boundary Lake Section
  • Northwest Mainline Loop – Bear Canyon Section
  • Grande Prairie Mainline Loop No. 2 – McLeod River Section
  • Liege Lateral Loop No. 2 – Pelican Lake Section
  • Kettle River Lateral Loop – Christina River Sectio

2.  Two compression stations:

  • Alces River Compressor Station Unit Addition
  • Otter Lake Compressor Station Unit Addition

3.  Additions and related components, including valve sites, auxiliary buildings and yard piping.

4.  Temporary infrastructure such as access roads, stockpile sites, construction camps and contractor yards during construction.

If regulatory approval is obtained, construction is proposed to start in late 2016, with an anticipated in-service date in 2017.

The Project Description includes designated physical activities listed in the Regulations Designating Physical Activities (Regulations) under the Canadian Environmental Assessment Act, 2012 (CEAA 2012), specifically the construction of over 40 km of new pipeline. As a result, the Project is a designated project for the purposes of CEAA 2012 for which the NEB will be the responsible authority.
