MYTH: Compressor stations will be flaring gas into the air, and disrupt the community with bright lights and noise all night long.
FACT: There are no routine gas emissions from the compressor stations.
Any venting at the station would only be done under controlled conditions for pipeline and station maintenance or as a result of a pipeline emergency. There are no flare stacks proposed for our compressor stations and little to no gas emissions.
TransCanada is a recognized leader in greenhouse gas emissions management, with particular emphasis on methane emissions management programs. Noise levels will be at or less than 40 decibels when measured 1.5 km from the compressor station. As a point of comparison, normal conversation at one metre is 60 decibels. Noise levels are routinely monitored to ensure they remain in compliance.
We minimize the noise generated by the stations through the use of engineered noise suppression devices, such as silencers, baffles and sound absorbing liners. The largest source of station noise is from the gas turbines used to power our gas compressors. These units are located within a soundproofed acoustical enclosure which is housed within compressor buildings, and the builds are built to further dampen noise.
Our compressor stations are unmanned and facility lights are off at night (except for safety lights over doorways) unless there are maintenance activities being conducted.
