The appellant brought a motion to stay a Director's Order requiring environmental investigation and reporting regarding potential trichloroethylene (TCE) contamination at its site, pending an appeal hearing.
The Tribunal found it had jurisdiction to grant a stay under section 143 of the Environmental Protection Act, as the contamination did not pose an immediate danger to health or safety.
However, applying the RJR-MacDonald test, the Tribunal denied the stay because the appellant failed to demonstrate irreparable harm, noting that potential compliance costs could be pursued in ongoing civil litigation.
Furthermore, the balance of convenience favoured the public interest in identifying the source of the TCE contamination.
