Notice of permit

Regional or Local Number: DFO-17-HQUE-00116

Notice is hereby given that pursuant to the provisions of section 73 of the Species at Risk Act permit no. DFO-17-HQUE-00116 is issued.

Purpose:
Activity affecting the species is incidental to the carrying out of the activity

Description:
The Department of National Defence will remove and dispose of 150 UXO (unexploded ordnance) within the former firing range (CYR 606) near Landroche Channel at Baie-du-Febvre in Lake St. Pierre. The 150 UXOs cannot be safely moved and will be detonated on site, in the aquatic environment. Notwithstanding mitigation measures, the explosions could cause fish to die, including some species at risk near the explosion sites.

Start Date: 2017-08-01   End Date: 2017-12-31

Issuing Authority: Department of Fisheries and Oceans

Authority Used:

  • Species at Risk Act

Location of Activity (province, territory or ocean):

  • Quebec

Affected Species:

Pre-Conditions:
a) Alternatives were considered and the best solution was adopted. For safety reasons, unexploded ordnance (UXO) equipped with a rocket cannot be moved and must be detonated in place. b) Measures will be taken to mitigate the negative impacts of the activity on the species and their habitat. The work will be completed outside the sensitive period. Use of sandbags will reduce explosion shock waves, and measures will be taken to haze the fish before each detonation to reduce mortality risks to a minimum. c) Effects on survival and recovery: The proponent plans to use a detonating cord or a cofferdam to create a fish exclusion area, as well as sandbags to contain the explosion and reduce the lethal range. In addition, given the time of year when the project will take place, incubating eggs and fish larvae are unlikely to experience sub-lethal effects from vibration (particle velocity) and pressure waves caused by the detonations, as the spawning activity is over and the rearing period is well underway so juveniles are mobile. These measures make it possible to manage the issue of the mortality risk for individuals. Given that there are approximately 150 objects to be detonated in situ and little likelihood that species at risk will be present at these sites at the time of year when the work will take place, there are still mortality risks but they can be characterized as low. Also, the work will have little impact on the habitat itself. For these reasons, the project is unlikely to threaten the survival or recovery of the Copper Redhorse, Eastern Sand Darter, Channel Darter, Bridle Shiner, River Redhorse or Striped Bass (St. Lawrence River population).
