Brossard Air Quality Report - August 2018

Note: The results for August 2018 show that on 10 days during the month, the level of particle pollution exceeded the acceptable levels established by the Government of Canada. It has been confirmed that though not entirely related to the construction activities for the new Champlain Bridge, a pollution levels were due in part to preparatory and construction work on permanent noise barriers to protect residents located along access road 132, which are part of the project. The close proximity of the air quality monitoring station to the work zone account for some of these exceedances. This is despite mitigation measures put in place by the private partner at the construction site in Brossard to minimize dust emissions. The non-exhaustive list of mitigation measures put in place by the private partner at the site are : watering of exposed surfaces, hydraulic seeding/stabilization of stockpiles, frequent passage of dedicated sweeping trucks, wheel washing areas for the trucks as well as the regular application of dust suppressant.
