From: Environment and Climate Change Canada

This consultation ran from February 16, 2019 to June 10, 2019.

The Government of Canada sought public comments on proposed amendments to the Metal and Diamond Mining Effluent Regulations for the Sisson Mine Project.

About the Sisson Mine Project

The Sisson Partnership (Proponent) is proposing to develop an open pit tungsten and molybdenum mine located approximately 60 kilometres northwest of Fredericton, New Brunswick. It is expected that the mine will be in operation for an estimated 27 years.

The Proponent intends to use water bodies frequented by fish to dispose of the mine waste (tailings and waste rock) that will be generated by the mining operations. Subsection 36(3) of the Fisheries Act prohibits the deposit of deleterious substances into waters frequented by fish, unless authorized by regulation. The Metal and Diamond Mining Effluent Regulations (MDMER) include provisions to allow the use of waters frequented by fish for the disposal of mine waste. The objective of the amendments is to authorize the storage of tailings and waste rock in two water bodies frequented by fish.
