On April 17, 2017, during a routine inspection, CNL was made aware of a leak in an underground pipe at the Port Granby Project Long-Term Waste Management Facility site. Upon discovery of the leak, the pipe was isolated to stop the flow of water, which was being pumped from the existing waste management facility for treatment at the Port Granby Project Waste Water Treatment Plant. The leak resulted in untreated water being released on the site. Upon investigation, the source of the leak was identified and repaired, and the pipe was put back in service on April 19, 2017.
