Notice of permit
Regional or Local Number: DFO-17-HCAA-00700
Notice is hereby given that pursuant to the provisions of section 73 of the Species at Risk Act permit no. DFO-17-HCAA-00700 is issued.
Activity affecting the species is incidental to the carrying out of the activity
Culvert maintenance over Fourteen Mile Creek, where Redside Dace is known to be present, is required. Structural improvements include the removal of the deteriorated concrete from the walls and soffits, and patching with new material. These works require site isolation, dewatering activities, and relocation of fishes.

Location of Activity (province, territory or ocean):
a) Alternatives: The do-nothing alternative does not meet MTO’s health and safety obligation to the travelling public. Rehabilitation of the current culvert structure is the preferred alternative based on a survey of the culvert’s condition, meeting the goal of maintaining the health and safety of the highway, and for economic and biological reasons. This alternative requires less time in the regulated habitat to perform patch and repair work than a full replacement, and is the most cost effective alternative associated with the works. Replacement of the culvert is not preferred as it has the greatest costs associated with the works. Biologically, the temporary impact footprint (i.e., construction limit and vegetation removal) to regulated habitat would be larger, as it would require a longer time period working within the creek. b) Measures to minimize impact: Environmental Protection for Construction in Waterbodies and Waterbody Banks will be conducted in accordance with established best management practices (e.g., OPSS 182). Erosion and Sediment Control (ESC) best management practices are to be used for the duration of the work. All ESC measures will be inspected and maintained to ensure they are functioning as intended throughout construction, until such time that disturbed areas have been stabilized. The control of water from dewatering operations is to be conducted in accordance with best management practices (e.g., OPSS 518). Fish rescue and relocation in isolated areas within the watercourses will be undertaken by a fisheries biologist 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 with the requirements of the License to Collect Fish for Scientific Purposes obtained from the MNRF. A qualified Fisheries Contracts Specialist, approved under the Fisheries Compliance During Contracts Speciality in MTO’s Registry, Appraisal and Qualification System (RAQS) will be on-site to monitor all in-water construction work within Redside Dace habitat, as defined by the MNRF. Fish screens will be used on all pumps to avoid fish entrainment during dewatering operations. A relocation of fishes would be required for this project regardless of mitigation measures. c) Effects on survival and recovery: The fish relocation has the potential for short-term reduction in fitness due to stress from handling. There may be potential mortality during fish relocation. Relocation of fishes will be carried out by a 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. The culvert rehabilitation may result in a decrease in suitable water quality needed by the species, and therefore a decrease in population. There may be potential mortality during construction works. Appropriate mitigation measures will be put in place to prevent negative impacts during construction. It is expected that there will be little impact if any to any species at risk.
