North Corridor Expansion Project Caribou Habitat Restoration and Offset Measures Plan April 2019 1.0 INTRODUCTION NOVA Gas Transmission Ltd. (NGTL), a wholly owned subsidiary of TransCanada PipeLines Limited (TransCanada), is applying to the National Energy Board (NEB) for a Certificate of Public Convenience and Necessity pursuant to Section 52 of the NEB Act to construct, own, and operate new pipeline facilities in Alberta that will form an integral part of the existing NGTL System. These facilities are referred to as North Corridor Expansion Project (the Project) and are described in more detail below. Two of the Project components occur within mapped caribou range. The Project consists of three pipeline sections, totaling approximately 81 km, that will loop the existing NGTL North Central Corridor (NCC) and Northwest Mainline (NWML) natural gas pipelines in Alberta, as well as construction and operations of a compressor station unit addition and associated connectivity piping. Components of the Project are as follows: • NCC Loop (North Star Section 2) consisting of approximately 24 km of 1,219-millimetre (mm) outside diameter (O.D.) (nominal pipe size [NPS] 48) pipe with tie-in points at valves NCCA 90 and NCCA 100 of the existing NCC pipeline. The North Star Section 2 is located approximately 20 km north of the Town of Manning, Alberta. • NCC Loop (Red Earth Section 3) consisting of approximately 32 km of 1,219-mm O.D. (NPS 48) pipe with tie-in points at valves NCCA 30 and NCCA 40 of the existing NCC pipeline. The Red Earth Section 3 is located approximately 45 km north of the Hamlet of Red Earth Creek, Alberta. • NWML Loop No. 2 (Bear Canyon North Extension) consisting of approximately 25 km of 914-mm O.D. (NPS 36) pipe with tie-in points at valves NW35 and NW50 of the existing NWML and the Alces River Compressor Station. The Bear Canyon North Extension is located approximately 50 km southwest of the Hamlet of Worsley, Alberta. • Hidden Lake North Compressor Station Unit Addition (Hidden Lake North Unit Addition) – consisting of a 30 MW compressor unit addition and related components at or near the existing Hidden Lake North Compressor Station. The Hidden Lake North Unit Addition is located approximately 100 km north of the Hamlet of Worsley, Alberta. The proposed pipelines will generally require an approximately 32-m-wide construction right-of-way (ROW) with additional temporary workspace (TWS) of variable widths to accommodate safe pipeline construction activities (e.g., at staging areas, soil storage areas, crossing). Approximately 77 km (95 percent) of the proposed pipeline routes parallel the existing NGTL ROW or other existing linear disturbances, such as pipelines, roads, and electrical power lines. Existing access roads will be used as deemed practical. Temporary infrastructure, such as access roads,
