Notice of permit
Regional or Local Number: DFO-17-HQUE-00202
Notice is hereby given that pursuant to the provisions of section 73 of the Species at Risk Act permit no. DFO-17-HQUE-00202 is issued.
Activity affecting the species is incidental to the carrying out of the activity
The proponent wishes to perform four geotechnical drilling operations around Prince Shoal, in the St. Lawrence Estuary, near Tadoussac. These drilling operations will be divided up among the north, south, east and west ends of the perimeter of the lighthouse pillar. The drilling must be completed as soon as possible because the Prince Shoal lighthouse is deteriorating. Lighthouse repair work is scheduled for 2018. The geotechnical drilling stage must be completed prior to the lighthouse repair work in order to identify the type of substrate in the work area, which will allow possible work methods to be determined.

Location of Activity (province, territory or ocean):
a) All the alternatives were analyzed. The proponent tried to complete the geotechnical drilling before the restricted period imposed by DFO, i.e., before June 1. However, due to poor weather conditions and to ensure the safety of workers, the work had to be stopped. Given the lighthouse’s location, work cannot be done in the fall. The drilling must take place during the calmest period, which is the summer. b) Measures to minimize impact: Drilling is authorized considering the brief duration of the drilling work (six days), the use of a subaquatic noise containment method combining insulating sleeves and bubble curtains, and the monitoring of belugas and blue whales by an observer with sufficient experience to detect marine mammals in different weather conditions. If a beluga or a blue whale comes within 600 m of the work area, the drilling activities will have to be stopped until the animal has moved more than 600 m away. In addition, there must be a recovery period of 8 continuous hours overnight, with no additional noise in the aquatic environment. Subaquatic sound levels will be monitored to measure the noise generated by the drilling activities in the aquatic environment. c) Effects on survival and recovery: The activity could adversely affect the summer feeding (weight gain period) of the beluga and blue whale, as well as the rearing of some individual beluga calves. Considering the brief duration of the work and the implementation of mitigation measures, no impact on the survival or recovery of these species is expected.
