Terra International (Canada) Inc., was recently was convicted of one offence under the Ontario Environmental Protection Act (EPA) and was fined $90,000 plus a victim fine surcharge of $22,500. The conviction stems from an incident that occurred on August 11, 2016 when the company reported an ammonia gas release to the Ontario Environment Ministry’s Spills Action Centre. It was subsequently determined that approximately 8.57 tonnes of liquid ammonia was released and contained, which resulted in a release of 997 kilograms of ammonia gas to the air over a two-hour period.
The ammonia release resulted in various adverse effects including the closure of nearby roads for approximately one hour. In addition, two reports were received alleging odours, with one of those alleging irritation; a third report alleged irritation, nausea and difficulty breathing; and employees at one neighbouring company reported evacuating for approximately two hours.
Upon discovery of the ammonia gas release, personnel from Terra conducted a root cause analysis which concluded that a previously unknown mechanical deficiency in an ammonia pump resulted in the failure of a vent pipe containing liquid ammonia.
