In 1954, when our refinery was being built, the Metropolitan Boulevard was just a dirt road. Only pasturing cows were watching the workers busy at work constructing our facility.
Today, we are at the heart of a densely populated area – pumps, compressors, air coolers, vents and pump trucks generate what is called the refinery rumble. Our noise studies in 2007 and 2013 have shown that this rumbling was maintained on average at 58 decibels (dB), despite increasing operations.
During the day, the noise we generate is lost amongst the background noise from the city, but at night, there remains only ours and this is why we remain very vigilant when it comes to noise.
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 dB.
Another example is the installation of silencers for some steam vents. When it is required to reduce noise impacts, we change the working schedule or method in the execution of our maintenance work.
In the summer of 2015, we conducted noise tests to help us identify which were the largest contributors to the 58 dB rumble coming from our refinery and temporary operations. We are actively working to reduce their noise impacts and the results look promising.
