The purpose of this project is to construct and operate a permanent soil treatment facility in Yellowknife, NT. The proposed permanent facility will include ongoing operation and maintenance of the cell as a biotreatment pad, as well as construction of an engineered cell to receive petroleum hydrocarbon-contaminated snow and water. Water will be treated on site by a package treatment plant. Treated water will be stored in a tank until it is confirmed that the water meets discharge criteria, after which it will be reused on site or released to the surrounding environment. Following bioremediation, treated soil meeting licence criteria will beneficially reused off site. Soil and water not meeting discharge/reuse criteria will be transported off site for disposal at a suitable facility.
The permanent facility will include: one engineered cell 50 m x 70 m for receipt, storage and treatment of petroleum hydrocarbon-contaminated soil (existing cell); one engineered cell designed for storage of up to 275 m3 of petroleum hydrocarbon-contaminated snow and water; one small package treatment plant to treat petroleum hydrocarbon-contaminated water; one or two above ground storage tank(s) for treated water storage; one small shed for storage of supplies, documentation and health and safety equipment.
