Notice of other simliar documents

Regional or Local Number: DFO-17-HCAA-00303

Notice is hereby given that pursuant to the provisions of section 74 of the Species at Risk Act other simliar documents no. DFO-17-HCAA-00303 is issued.

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

Canadian Pacific (CP) has requested an emergency authorization to complete immediate placement of a 140m long, 600mm thick riprap blanket extending up to 10m below the annual high water mark along the right bank of the Assiniboine River in Brandon, Manitoba. The work is to prevent ongoing shoreline erosion of the riverbank adjacent to a dike along the CP rail yard site. CP believes that further erosion will increase the likelihood of accelerated movement of the riverbank and subsequent movement of the dike, placing the CP Brandon yard and its infrastructure at a risk.

Start Date: 2017-04-14   End Date: 2017-05-15

Issuing Authority: Department of Fisheries and Oceans

Authority Used:

  • Species at Risk Act
  • Fisheries Act

Location of Activity (province, territory or ocean):

  • Manitoba

Affected Species:

a) Alternatives: Failure to stabilize the dike will result in its failure. The option to allow it to fail was considered and rejected as not feasible. b) Measures to minimize impact: Placement of riprap will be done in a controlled fashion by an excavator to minimize disturbance. Efforts will be made to isolate the area to the extent possible given the site conditions. Disturbance of riparian vegetation shall be minimized during equipment access and construction activities. Restored slopes shall be re-vegetated with native plantings (e.g. willow and native grasses). Instream footprint will be minimized to the extent possible to reduce disturbance to Mapleleaf and its habitat. Appropriate precautions will be taken to ensure that deleterious substances, including sediment, will not enter the water. c) Effects on survival and recovery: In Manitoba, the Mapleleaf COSEWIC Assessment and Status Report (2016) reports that the major threat to recovery is related to decreasing water quality resulting from agricultural activities. The proposed mitigation will minimize the impacts of proposed activity to Mapleleaf individuals, its residences, and habitat, and minimize the impacts to water quality. The proposed activity is outside the proposed critical habitat for the species. Mitigation proposed for this activity is standard for construction practices of this type.
