Noise prevention is a sound investment

							Sound levels at the Suncor Montreal Refinery are monitored regularly.
Environment advisor, Emmanuelle Bécaert, regularly monitors sound levels coming from the different units at the Suncor Montreal Refinery. Based on these results, noise levels are monitored, anomalies identified and actions taken to reduce sound level coming from our Montreal installations.

Suncor staff are vigilant when it comes to ensuring legal compliance for noise at the Montreal Refinery – at both night and day. 

In 1954, when the refinery was being built, the Metropolitan Boulevard was just a dirt road. Only pasturing cows were watching the workers busy with the construction of our facility. Today, we are at the heart of a densely populated area. Sound from the industrial activity taking place at the refinery is referred to as the ‘refinery rumble’ and is generated from:

  • pumps
  • compressors 
  • air coolers 
  • vents 
  • pump trucks

Our noise studies in 2007 and 2013 have shown that this rumbling was maintained within compliance, despite increasing operations. During the day, the noise we generate is lost amongst the background noise from the city. But at night, the  noise continues which is why we are vigilant about noise reduction to ensure we are legally compliant.

Keeping quiet measures

Various departments of the refinery have invested time and energy in noise prevention initiatives. For example, following the addition of new crude oil and distillate transfer pumps in our south terminal, we have been busy installing a sound barrier and an acoustic cover on the pipes that will reduce the noise by 18 decibels. Another example is the installation of silencers for some steam vents. Whenever possible, we change the working schedule or approach to our maintenance work to reduce noise impact.

In the summer of 2015, we completely remodelled the noise mapping of the refinery to help us identify the largest contributors to the industrial rumble coming from our refinery or temporary operations. We are actively working to reduce noise impacts and the results look very promising.
