No specific mitigation measure required
Follow-up required

44. New Champlain Bridge Corridor Project
• Main mitigation measures for the entire work site:
 Use variable-intensity back-up alarms
 Organize traffic to minimize backing up
 Control production of impact noise (truck tailgates)
 Make site supervisors and workers aware of the need to comply with noise
mitigation measures
• Monitor noise levels during construction
 At the beginning of critical activities, for verification purposes
 Once or twice every two weeks
 Check when there are complaints

46. New Champlain Bridge Corridor Project
Air Quality Management
• No expected impact on sensitive zones
• Main mitigation measures for the entire work site:
 Transport of materials in dump trucks with tarp covers
 Appropriate maximum speed for vehicles, to reduce dust emissions on access roads
or jetty
 Spraying water on surfaces
 Regular cleaning of the streets used by vehicles and machinery in order to remove
any accumulation of movable material and other debris
 If necessary, application of dust suppressant
• Monitoring to be done mainly for demolition activities
