Supporting Energy Transition in the Thetford Mines Region

Since fuel oil is the key source of energy used by industrial businesses in Thetford Mines, the region was seeking a solution to switch to cleaner, more efficient energy. Natural gas was chosen as an ideal transitional source of energy to help with regional economic development. BBA’s mandate was to assist Énergir with routing 52 km of natural gas pipelines and with measures to reduce environmental impacts.

OUR EXPERTS’ SOLUTIONS

​Installing natural gas pipelines posed an environmental challenge because sensitive areas had to be protected: over 60 streams and wetlands, as well as farmland. The presence of asbestos tailings in existing infrastructures was also a significant health, safety and environmental challenge.

When asked to advise Énergir about the best practices to adopt, BBA leveraged its vast environmental expertise to assess the impacts on the receiving environment and propose effective solutions to reflect the needs of local communities.

Special attention was given to protecting over 30 plant and animal species that make up the ecosystems affected by the work. The best solution was to avoid sensitive and high-value areas, including land where ferns are grown to feed dairy cows.

When crossing streams and wetlands was unavoidable, a directional drilling method helped avoid excavating in these areas of high ecological value. Mitigation measures were implemented to ensure water, soil and air quality was maintained. 

IN THE WORDS OF OUR CLIENT…

“BBA has proven to be a valuable ally in the field, ensuring that best environmental practices are applied.​”
