Newfoundland and Labrador Hydro Line Modifications in Gros Morne National Park

Newfoundland and Labrador Hydro (NL Hydro) is proposing to widen the Right of Way (ROW) corridors of five transmission lines that run through Gros Morne National Park. These lines are critical infrastructure, delivering electricity to national park facilities, enclave communities, and destinations north of the national park (i.e., over 9,000 customers). The transmission lines currently have higher service disruption rates than lines outside the park. During this five-year project, NL Hydro will work during the fall and winter to increase the five ROW corridors within the park from 9-15m to 19-29m in width, depending on the terrain. A two-zone approach will be used to reduce the impact of the widened ROW. With this two-zone approach, the existing ROWs (‘wire zones') will continue to be cleared of all trees and shrubs. The new ROW expansion areas (‘border zones') will be selectively cleared of trees tall enough to be in the wire security zone, while shorter trees and shrubs will be retained.

Scope: The Detailed Impact Assessment will assess the impacts of  a transmission line modification project on the Park's ecological integrity, visitor experience and cultural heritage values. The valued components to be assessed include vegetation – communities and species,  visitor experience – viewscapes, and World Heritage Site – Outstanding Universal Values.
