July 25^th, 2023 – The Montreal Port Authority (MPA) has determined that the proposed project Repair and optimization of the railway bridge at Pie-IX entrance of the Port of Montreal is not likely to cause significant adverse environmental effects.

The mitigation measures taken into account for this determination are as follows:

• Nuisance management (noise, vibration and dust):
  • Avoid operations during strong winds
  • Use water or dust suppressant on surfaces likely to emit dust
  • Cover soil piles
  • Limit work at night
  • Require dump trucks to be fitted with shock absorbers to prevent rattling
  • Require broadband back-up alarms
  • Create a loop to prevent machinery from reversing
  • Continuous vibration monitoring and measurement
  • Development and implementation of a noise management program
• Installation of a temporary retaining wall, respecting excavation slopes and management of accumulated water;
• Capture and management of surface water
• Management of soils, granular materials and other excavated materials
• Management of residual and hazardous materials
• Air quality management :
  • Frequent machinery inspections
  • Limitation of trucking and idling
• Protection of biodiversity and control of invasive alien species
• Management of environmental emergencies

Therefore, the MPA may perform any duty or function to enable the project to be carried out in whole or in part.
