Notice of permit

Regional or Local Number: DFO-17-HCAA-00702

Notice is hereby given that pursuant to the provisions of section 73 of the Species at Risk Act permit no. DFO-17-HCAA-00702 is issued.

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

Description:
The replacement of a clear span bridge with a wider clear span bridge at Sixteen Mile Creek, where Redside Dace is known to be present, is required. These works require site isolation, dewatering activities, and relocation of fishes.

Start Date: 2017-07-01   End Date: 2017-09-15

Issuing Authority: Department of Fisheries and Oceans

Authority Used:

  • Species at Risk Act

Location of Activity (province, territory or ocean):

  • Ontario

Affected Species:

Pre-Conditions:
a) Alternatives: Alternative 1, to do nothing, and Alternative 2, to improve local roads and transit, do not meet MTO’s obligation to construct the project in the study area in order to meet transportation needs. Alternative 3, to rehabilitate the existing culvert based on the condition of the structure, would require frequent and costly future rehabilitation, resulting in long-term disturbance of the creek, the regulated area, and the species inhabiting it, including Redside Dace. In Alternative 4, a single, 31.5 m span bridge, the temporary impact footprint to regulated habitat will be larger. Ultimately, the structure will still be located within the meander belt width, and the difference between this option and the preferred option is 6.5 m. In Alternative 5, a single 25.0 m span bridge, impacts to regulated habitat will occur due to construction and the structure will be located within the meander belt width. However, impacts associated with this design alternative will occur only once and could be offset with appropriate restoration of the creek and implementation of appropriate mitigation measures. The increased span also provides the potential for natural riparian vegetation to establish under the structure and dry passage for wildlife. b) Measures to minimize impact: Timing windows for in-water works for the period from July 1 to September 15 where in-water work is permitted, will be implemented, to protect sensitive life stages and processes of fishes, particularly Redside Dace. An isolation and containment plan to delineate temporary in-water work zones to allow work in the dry and maintain clean flow downstream and around the work zone at all times will be designed and implemented. The limit of any area to be disturbed shall be clearly marked prior to the commencement of work. Any fishes trapped within an isolated or enclosed area at the work site will be captured and safely relocated to an appropriate location in the same waters. Fishes may need to be relocated again, should flooding occur on the site. When using a pump, the intake shall be controlled to prevent entry of fishes and other aquatic wildlife, and any water intakes or outlet pipes shall be screened to prevent entrainment or impingement of fishes. A qualified fisheries specialist shall monitor construction activities in and around watercourses to ensure all related mitigation measures are properly installed, maintained, and are functioning effectively. Fish rescue and relocation of isolated areas within the watercourses will be undertaken by a Species at Risk Specialist using appropriate capture, handling, and release techniques to prevent harm and stress to fishes. Fishes will be released in suitable habitat downstream of the work area and in accordance the requirements of the Licence to Collect Fish for Scientific Purposes obtained from MNRF. An MTO Registry, Appraisal and Qualification System (RAQS) qualified Fisheries Contracts Specialist will be on site to monitor all in-water work construction within Redside Dace habitat, as defined by MNRF. Additional measures include standard Best Management Practices for contaminant and spill management, erosion and sediment control, bank stabilization and operation of machinery. c) Effects on survival and recovery: Impacts are temporary, and mitigation will reduce or eliminate most risks to Redside Dace. There will be a potential short-term reduction in fitness, increased stress, and mortality due to entrapment, capture, and relocation of fishes. Relocation of fishes will be carried out by qualified fisheries professionals using appropriate capture and handling techniques. As such, there is little likelihood of mortality. The activities have a low risk of negatively impacting the population in the area, and it is expected that there will be little impact, if any, to Redside Dace.
