Air Quality Management
• No expected impact on sensitive areas
• Monitoring, mainly for demolition activities • Dust blanketing using water cannons • Use of dust control liquid.

Light Management
39
• Problem essentially limited to site trailers and parking on western jetty: largest worksite facilities for the project are near the Pointe-Nord on Nun’s Island
• Two areas impacted: Evolo 2: adjustments made René Lévesque Blvd. (toward Pointe-Nord): new challenge
• Human health and safety imperative and operational
security.
New Champlain Bridge Corridor Project
Vibration Management
40
• Continuous seismographic monitoring: an alert is received if the 25mm/s criterion is exceeded; adjustments are then made to work methods in order to remain within the criterion.
• The 25 mm/s criterion is based on a low probability of cosmetic damage (e.g., cracks in gypsum) and is recognized by the MTQ for residential buildings.
• Protective cushions are used to dampen debris impact shocks during
demolition.
• Visual assessment prior to construction and re-assessment afterwards.

Follow-up of actions from Last Meeting
New Champlain Bridge Corridor Project
Action follow up
42
SSL • West jetty site luminosity: adjustments made. • Possibility of having a noise abatement wall between Sud-Ouest and the railroad: acoustic
analysis is ongoing. • Removal of buildings from May St. and the effect on neighbourhood tranquility, plus
concerns expressed with regard to bringing the A15 closer to the Poudrière sector: Temporary noise abatement walls will be installed between LaSalle and Wellington Permanent noise abatement walls to be erected later.
INFC • Environmental compensation for the project as a whole (i.e. GGs: discussions ongoing • Possibility of a 4th lane on the Nun’s Island Bridge linking Nun’s Island to Verdun:
discussions ongoing. • Conversion of temporary Nun’s Island Bridge into park: under review.
Ville de Montréal • Access to Nun’s Island channel for Pointe-Saint-Charles: under review.
