Project Information

NOVA Gas Transmission Ltd (NGTL) has applied, pursuant to section 58 of the National Energy Board Act (NEB Act), to construct 21.5 kilometres of new pipeline, two compressor station unit additions, and related facilities. The proposed pipeline (known as the Rocky View Section) requires 21.5 km of new permanent right-of-way and temporary workspace, which would be located on privately held and Provincial Crown land, as well as on lands owned by a mixture of industry, and the municipalities of Rocky View County and the Town of Cochrane.

The proposed pipeline begins at NGTL’s existing WAS110 Valve Site, located approximately 0.8 km north of the Town of Cochrane, AB, and ends at NGTL’s existing WAS100 Valve Site located approximately 16.6 km west of the city of Calgary, AB within Rocky View County.

The Turner Valley Compressor Station Unit Addition will be located at NGTL’s existing Turner Valley Compressor Station located approximately 3 km northwest of Turner Valley, AB.

The Burton Creek Compressor Station Unit Addition will be located at NGTL’s existing Burton Creek Compressor Station approximately 39 km west of Claresholm, AB.
