On September 5th, there was a chlorine gas leak at the City of Corner Brook’s Water Treatment Plant. The Corner Brook Fire Department was called in for a HAZMAT response. At Monday night’s public meeting, Deputy Mayor Linda Chaisson says the leak was found to be from the vacuum regulator on tonner #2. It occurred because of an improperly sealed threaded connection on the regulator. The leak was determined to be small, and the concentration of Chlorine gas was low, with maximum readings of 4-6ppm. In accordance with the WTP Chlorine Gas Leak Response Plan, it was determined it would be safe for WTP staff to enter the room in a level B suit, less than 25 ppm. The regulator was removed and replaced with the spare unit and sent out for inspection. On September 26 the plant was shut down overnight (approx. 3.5hrs.) to replace the Raw Water Flow Control Valve.
