Parkland Corp. has released a review into an unplanned shutdown of its Burnaby, B.C., refinery in January that blanketed parts of Metro Vancouver with a foul stench.

The review released last week says unusually cold weather triggered a series of events leading to the release of a noxious odour that generated more than 100 complaints from residents.

It says the cold weather resulted in a shutdown on Jan. 12, but as crews spent days trying to get the facility back online, they detected a 香蕉视频直播渟trong odour香蕉视频直播� on the morning of Jan. 21, followed by a 香蕉视频直播渓oud pop香蕉视频直播� and a 香蕉视频直播済reen-black香蕉视频直播� plume being emitted from the refinery香蕉视频直播檚 stacks.

It says the problems 香蕉视频直播渕ay have been caused by improper closing, valve leakage, or foulant in the system.香蕉视频直播�

The site was evacuated of non-essential personnel, emergency responders were notified and public advisories were issued soon after, the report says, but 香蕉视频直播渂roader stakeholder consideration would have improved communications.香蕉视频直播�

In a written statement, the City of Burnaby says it it香蕉视频直播檚 pleased to see Parkland taking steps to address the release of emissions, and to improve communications with the public and other stakeholders.

香蕉视频直播淲e look forward to seeing these recommendations put into action,香蕉视频直播� the statement said.

Parkland香蕉视频直播檚 report says it wasn香蕉视频直播檛 until March 29 that normal operations at the refinery resumed.

The report also says the length of the January cold snap caused problems with instruments at the refinery, hampering sensors that 香蕉视频直播渄id not have a history of being susceptible to freezing.香蕉视频直播�

As the odour blanketed parts of Metro Vancouver, the regional federation of municipalities said the air contained elevated contaminant levels but didn香蕉视频直播檛 breach pollution standards.
