Managing EIA with the challenge of a watercourse diversion for the proposed Picadilly Mine


Picadilly Mine and Brine Pipeline, Environmental Impact Assessment


Amec Foster Wheeler was retained to manage the environmental studies in addition to geotechnical work for the proposed Picadilly mine site and brine pipeline in Penobsquis, NB.

Project highlights included: assessment and monitoring of almost fifty watercourse and wetland crossings; significant archaeological surveys including almost three thousand  test pits; and significant social challenges in the routing of the brine pipeline resulted in the necessity to adapt the project design while remaining within the initial timeline and budget.

Amec Foster Wheeler’s extensive experience with linear projects and our focus on understanding client needs were key factors in achieving this while remaining within budget and keeping the project on schedule. For the brine pipeline an application to the NB Energy and Utilities Board was also required. Separate public consultation and a public hearing process were required to complete this application. Our personnel provided expert witness testimony and hearing support for the public hearings.

"Specific constraints encountered during the project included the need for a several hundred metre (m) watercourse diversion on the proposed Picadilly mine site. Our aquatic biologists in conjunction with our hydrology and hydrogeology team were able to design a diversion that satisfied the requirements of DFO. Amec Foster Wheeler personnel oversaw the installation of the watercourse diversion to ensure that the diversion was installed in keeping with all SSEPP requirements."
