British Columbia Hydro and Power Authority at Site C was served a non-compliance order regarding requirements to minimize sulphide mineral exposure to air and water.
The order was from the Environmental Assessment Office (EAO) dated April 21st, 2022.
From August 15th to 19th, 2021, EAO Compliance and Enforcement inspected the project and discovered they were not compliant with ‘Condition 3.’
This condition requires B.C. Hydro to reduce the exposure time of excavated surfaces and fill areas that contain acid generating and potentially acid-generating material.
They must do this by covering the material with natural material that is porous and absorbant to minimize leakage.
They must also capture and, if required, treat any surface runoff from exposed or excavated surfaces that contain acid generating or potentially acid-generating material before discharge.
This order requires them to do this to the satisfaction of EAO compliance and enforcement unless authorized by the EAO.
